Technical Field

The present invention relates to the field of sludge crushing, in particular to a vertical sludge crusher, and more particularly to a vertical sludge crusher having a linearly moving wall scraping and sludge removing device, and also to a method for sludge crushing using the vertical sludge crusher according to the present invention.

Background

The current deep dehydration treatment of sludge generally adopts a mechanical filter-pressing dehydration mode to carry out solid-liquid separation on the sludge. Compared with other solid-liquid separation modes, the mud cake after mechanical filter pressing dehydration has high solid content. The treated sludge cake is in a block shape, generally has the water content of 40-75%, has high hardness, is not easy to break, and has partial viscosity. In order to facilitate the subsequent sludge transportation and treatment, the sludge cake is usually subjected to a crushing treatment.

Mechanical crushing of sludge is a common crushing treatment, and the used equipment is mainly a sludge crusher, including but not limited to jaw crushers, gyratory crushers, cone crushers, hammer crushers, roller crushers and vibratory crushers. Recently, vertical sludge crushers, which employ a rotating crushing member and a vertical installation manner, are increasingly employed due to their small footprint, convenient operation and maintenance characteristics, and low cost. However, in the vertical sludge crusher, when the sludge block is crushed by the crushing member rotating at a high speed, the sludge is easily adhered to the inner wall of the crusher housing due to the viscosity of the sludge. If not in time clear up, the mud on the shells inner wall will be amasss the more thick more, not only is difficult to clear up, leads to the inner space of breaker to diminish gradually moreover to easily lead to broken part to damage.

One conventional way is to shut down the sludge adhered to the inner wall of the vertical sludge crusher in order to clean it, but doing so affects production, reduces efficiency, and increases labor and maintenance costs. Another way to solve the problem of sludge sticking to the inner wall is to provide a sludge removal device. It is known to provide a rotary type wall scraping and mud removing device in a vertical sludge crusher, wherein a scraper of the rotary type wall scraping and mud removing device is fixedly connected with a rotating shaft of the vertical sludge crusher and rotates at a high speed together with the rotating shaft when in operation, so that sludge adhered to the inner wall of a housing is scraped by the scraper. However, since the sludge has a characteristic of being more viscous and more viscous with stirring, when the scraper of the rotary type wall scraping and sludge removing device scrapes the sludge with high-speed rotation, a side effect of stirring the sludge adhered to the inner wall is rather played to a certain extent, so that the sludge is more viscous and more solid with more scraping, the sludge or dust is more viscous and more viscous, and the sludge adhered to the inner wall forms lumps and is difficult to clean. Furthermore, the blades of the rotary type wall scraping and silt removing apparatus rotate at high speed together with the rotating shaft of the crusher when in operation, which also makes the blades thereof highly vulnerable to damage or wear.

Referring to fig. 1 and 2, a vertical sludge crusher 1 according to an embodiment of the present invention is shown in longitudinal and perspective cutaway views, respectively. The vertical sludge crusher 1 includes a housing 2, the housing 2 being generally vertically arranged and may include a barrel 201, a base 202, and an upper cover 203. It should be noted here that the descriptions referred to in this application as referring to the orientation such as "upper", "lower", "upper" and "lower" are made with reference to the mounting arrangement of the vertical sludge crusher 1 during normal use, for example, the mounting arrangement of the vertical sludge crusher 1 shown in fig. 1. That is, the housing 2 of the vertical sludge crusher 1 includes, in order from top to bottom, an upper cover 203, a barrel 201, and a base 202. The barrel 201 is formed in a cylindrical shape with both ends open, and the upper cover 203 covers the upper end opening of the barrel 201 and is rotatably or fixedly connected thereto in any known suitable manner; base 202 is also rotatably or fixedly attached to the lower end opening of barrel 201 in any known suitable manner. Such suitable means include, but are not limited to, for example, welding, riveting, screwing, bearing (e.g., thrust bearing, etc.) connection, and the like. Further, the upper cover 203 and the barrel 201, or the base 202 and the barrel 201, or the upper cover 203 and the base 202 and the barrel 201 may be integrally formed by a suitable means, such as casting.

In the embodiment shown in fig. 1 and 2, the barrel 201 has a cylindrical shape. However, the barrel 201 may have any other suitable shape, including, but not limited to, a cylindrical shape having a rectangular, triangular, square, or polygonal cross-section, and when the barrel 201 takes other shapes, the shapes of the upper cover 203 and the base 202 are changed accordingly to fit the upper end opening and the lower end opening of the barrel 201, respectively. The barrel 201 is provided with slots, such as slots 201a, 201b, 201c seen in fig. 1 and 2, near its upper end opening. In the embodiment shown in fig. 1 and 2, the barrel 201 is provided with four slots near its upper end opening. However, other numbers of slots may be provided as desired.

the upper cover 203 has a shaft hole 203a at the center thereof to receive and support the rotating shaft 501 of the vertical sludge crusher 1. In the illustrated embodiment, the upper cover 203 is further provided with a feed inlet 3 for receiving sludge. However, it is easily understood that the feed port 3 may be provided on the barrel 201, for example, at a suitable position in the upper portion of the barrel 201.

With continuing reference to fig. 1 and 2, and in particular to fig. 4, there is schematically shown in perspective view a base 202 in the vertical sludge crusher 1. The base 202 has a cylindrical table 202a at the center thereof, and the cylindrical table 202a includes a shaft hole 202b at the center thereof so as to receive and support the rotating shaft 501 of the vertical sludge crusher 1. In the illustrated embodiment, the base 202 further includes a circular outer frame 202c and a plurality of support rods 202 d. In the embodiment shown in fig. 4, the base 202 has four support rods 202 d. It will be readily appreciated that the base 202 may have any other suitable number of support rods 202 d. The outer frame 202c is used to connect the base 202 to the barrel 201. The support rod 202d is used to connect the outer frame 202c and the cylindrical table 202a at the center of the base 202 to each other, so as to support the cylindrical table 202a and the rotation shaft 501 received in the shaft hole 202b of the cylindrical table 202 a. The support rods 202d are uniformly distributed in the circumferential direction, so that discharge ports 4 for discharging the crushed sludge are formed between the adjacent support rods 202 d. It will be appreciated that the base 202 may take other forms as well, including, but not limited to, for example, a circular plate provided with a spout.

as shown in fig. 1 and 2, when the upper cover 203, the base 202, and the barrel 201 are assembled to form the housing 2 of the vertical sludge crusher 1, the center of the shaft hole 203a of the upper cover 203 and the center of the shaft hole 202b of the cylindrical table 202a are both located on the longitudinal center axis of the barrel 201.

the vertical sludge crusher 1 includes a rotating shaft 501. The rotation shaft 501 is arranged in the vertical direction such that the longitudinal center axis thereof coincides with the longitudinal center axis of the barrel 201, the lower end of the rotation shaft 501 passes through the shaft hole 202b of the cylindrical table 202a of the base 202 and is rotatably supported in the shaft hole 202b, and the upper end of the rotation shaft 501 passes through the shaft hole 203a of the upper cover 203 and is rotatably supported in the shaft hole 203 a. The rotating shaft 501 includes a bottom flange 503, and the bottom flange 503 is adapted to abut against the upper surface of the cylindrical table 202a when assembled, thereby enabling the rotating shaft 501 to be supported on the cylindrical table 202 a. The rotating shaft 501 further comprises a number of flanges 504 distributed along its longitudinal length, which flanges 504 are used for connecting and fixing respective crushing members. It will be readily appreciated that bottom flange 503 and/or flanges 504 distributed along the longitudinal length of rotating shaft 501 may be integrally formed with rotating shaft 501, but may also be a separate component fixedly attached to rotating shaft 501 by any suitable means (e.g., welding, threading, riveting, etc.). In fig. 1 and 2, it is shown that four flanges 504 are provided on the longitudinal length of the rotary shaft 501. It will be readily appreciated that this is merely an example. Any suitable number of flanges 504 may be provided at any suitable spacing, as desired. The upper end of the rotary shaft 501 may be connected to a suitable power means via any suitable means so as to be driven to rotate.

The vertical sludge crusher 1 further comprises at least one crushing member for crushing a sludge mass fed into the vertical sludge crusher via the feed opening 3. In the embodiment shown in fig. 1 and 2, the crushing member is a crushing chain 502, one end of which is connected to a flange 504 of the rotating shaft 501 and the other end of which is a free end, whereby when the rotating shaft 501 rotates, the crushing chain 502 is brought to rotate together. When the sludge block enters through the feed port 3, the crushing chain 502 rotates at a high speed, so that the sludge block can be effectively beaten or impacted into fragments or granules or powder to realize sludge crushing. As shown, each crushing chain 502 is formed by four looped links that are interlocked. Each link has the same shape, wherein the link connected to the flange 504 has an opening so as to be fixedly connected to the flange 504 by bolts. It will be appreciated that other suitable means of fixedly connecting the crushing chain 502 to the flange 504 may be employed, including but not limited to welding, hinging, riveting, and the like. The length of the crushing chain 502 may be set according to the size of the inner space of the housing 2 of the vertical sludge crusher 1. That is, the horizontally extending length of the crushing chain 502 should be smaller than the inner radius of the housing 2 to avoid interference during operation. When the mud removing device 6 is provided on the inner wall of the housing 2 of the vertical sludge crusher 1, the length of the crushing chain 502 extending horizontally outward with the rotation shaft 501 as the center should be smaller than the distance from the radial inner surface of the wall scraper in the mud removing device 6 to the rotation shaft 501 to avoid interference during operation.

In the illustrated embodiment, three crushing chains 502 are attached to each flange 504. It will be appreciated that this is merely an example. More or fewer crushing chains 502 may be provided on each flange 504, as desired. For example, different crushing chains 502, for example, different numbers and/or lengths of crushing chains, may be selected according to the size of the crusher, the application, the properties of the sludge (e.g., the current sludge state, the sludge cohesiveness, the water content, etc.), the requirements for sludge particles (e.g., the size of the final sludge particles after crushing), and the throughput. Furthermore, each link of the crushing chain 502 may also have a different shape and/or size, e.g. the individual links may also have different lengths and/or widths in order to achieve the desired crushing effect.

additionally, it will be further appreciated that the crushing members may take other forms including, but not limited to, for example, rods, bars, tubes, square tubes, blades, cutters, blades, etc. fixedly attached at one end to the rotating shaft 501 and extending radially outward therefrom. Further, it is easily understood that these crushing members may be used in combination, for example, a rod or a bar may be provided with a cutter or a blade, or a crushing chain may be used together with a rod, a bar, a tube, a square tube, a blade, a cutter or a blade.

The vertical sludge crusher 1 further comprises a sludge removing device 6 for scraping or cleaning sludge adhered to the inner wall of the barrel 201. Referring to fig. 3, the mud removing device 6 includes a wall scraper 601, an actuating rod 602, and a transmission 603. The wall scraper 601 is used for scraping sludge adhered to the inner wall of the barrel 201, the actuating rod 602 is used for actuating the wall scraper 601 to perform linear reciprocating motion, and the transmission device 603 is used for driving the actuating rod 602 to rotate.

The wall scraper 601 has an outer edge profile corresponding to the profile of the inner wall of the barrel 201 and at least one threaded hole 601 a. In the illustrated embodiment, the mud removing device 6 has five wall scrapers 601, each wall scraper 601 having a circular ring shape and four threaded holes 601a, wherein the four threaded holes 601a are evenly distributed in the circumferential direction. The five wall scrapers 601 are arranged in a sequential distribution along the longitudinal central axis of the cylinder 201, spaced at equal intervals from each other. However, it is readily appreciated that in other embodiments, the wall scraper 601 may not be a unitary circular ring, but may take the shape of a segmented plurality of circular segments. In fact, the wall scraper 601 may have any suitable shape as long as its outer edge contour conforms to the inner wall contour of the barrel 201. For example, for a shaft having a rectangular, square or polygonal cross-section, the outer edge profile of each scraper may also be rectilinear so as to correspond to the planar profile of the respective side of the inner wall of the shaft. Furthermore, the number of wall scrapers 601 can be selected according to the actual need.

The actuating rod 602 is provided with threads for threaded engagement with a threaded hole 601a in the wall scraper 601, and the upper portion of the actuating rod 602 is provided with a power input member for receiving power to rotate the actuating rod 602. In the embodiment shown in fig. 1, 2, 3 of the present application, the power input member is a worm gear 602 a. The worm wheel 602a is engaged with a corresponding member provided outside the cylinder 201 through a groove 201a formed on the cylinder 201 to receive power. However, it will be appreciated that the power input member may take other forms as well, including, but not limited to, for example, sprockets, friction wheels, gears, etc., as desired. Further, a power input member may also be provided at a lower portion of the actuating lever 602 or at any other suitable position as long as it can receive a power input from a corresponding member outside the barrel 201, as required. The upper and lower ends of the actuation rod 602 are supported in upper and lower bearings 605 and 606, respectively. The upper bearing 605 and the lower bearing 606 can be fixed to the upper cover 203 and the base 202, respectively, in any suitable manner such that the actuation rod 602 is arranged parallel to the longitudinal central axis of the barrel 201. The upper bearing 605 and the lower bearing 606 may be any suitable type of bearing including, but not limited to, for example, sliding bearings, rolling bearings, and the like. When the actuator rod 602 is driven in rotation, it can bring the threadedly engaged wiper 601 in linear reciprocating motion along the actuator rod 602.

The transmission 603 in the de-mud apparatus 6 is adapted to receive power input from a suitable external power source and to transmit the input power via a suitable power output member to the power input member of the actuating lever 602, thereby driving the actuating lever 602 to rotate. It will be readily appreciated that the power take off part of the transmission 603 is complementary to the power input part on the actuating lever 602. For example, if the power input member on the actuation lever 602 is a sprocket or friction wheel, then the power output member of the transmission 603 is a chain or friction belt, respectively. For the embodiment shown in figures 1, 2, 3 of the present application, the power input on the actuation lever 602 is a worm gear, and thus the power output of the transmission 603 is correspondingly a worm. As shown in fig. 3, the transmission 603 may include at least one drive rod 603b having worm segments 603c, the number of which matches the number of the actuation rods 602. In addition, the transmission 603 also includes a power source coupling member for coupling the transmission 603 to a suitable external power source.

with continued reference to fig. 3, there is shown an assembled de-sliming device 6 for use in the embodiment shown in fig. 1 and 2. In this embodiment, the mud removing device 6 includes five wall scrapers 601, each of the wall scrapers 601 has a circular ring shape and four threaded holes 601a, wherein the four threaded holes 601a are evenly distributed in the circumferential direction, and the five wall scrapers 601 are arranged to be sequentially distributed in sequence along the longitudinal central axis of the cylinder 201 at equal intervals from each other. The four screw holes 601a of each of the wall scrapers 601 are aligned one by one in the vertical direction, thereby forming four groups of five screw holes which are aligned one by one in the vertical direction. Four actuating rods 602 are inserted through the four vertically aligned screw holes and threadedly engaged with each of the screw holes, respectively, to thereby arrange five wall scrapers 601 in sequence in the vertical direction. The worm wheel 602a on the actuating lever 602 is engaged through a corresponding slot 201a in the barrel 201 with a corresponding worm section 603c on a drive rod 603b in the transmission 603 for driving by the worm section 603 c. In the embodiment shown in fig. 3, the transmission 603 comprises four transmission rods 603b, each transmission rod 603b having a worm segment 603c and two bevel gears 603d arranged at both ends of said transmission rod 603b, the bevel gears 603d arranged at the ends of each transmission rod 603b being interconnected with the bevel gears of the corresponding other transmission rod to form a square configuration as shown in the figure. One of the four drive rods 603b also comprises a gear 603a as a power source coupling part for driving the gear 603a by a suitable external power source, thereby operating the de-sludge device 6. Each drive rod 603b is fixedly secured to the barrel 201 by two fasteners 604. When an external power source drives the four drive rods 603b to rotate via the gears 603a, the worm section 603c of each drive rod 603b drives the worm gear 602a of the corresponding actuator 602 to rotate, causing the corresponding actuator 602 to rotate. Since the actuating rod 602 is threadedly engaged with the threaded hole 601a of the wall scraper 601, the wall scraper 601 is linearly reciprocated along the longitudinal central axis of the barrel 201 by the rotation of the actuating rod 602, thereby achieving the purpose of scraping off sludge adhered to the inner wall of the barrel 201.

Referring now to fig. 5, there is shown another embodiment 601' of the wall scraper, which wall scraper 601' overall also has the shape of a circular ring and has four threaded holes 601a ' evenly spaced in the axial direction. Fig. 6 shows a cross-sectional view of the wall scraper 601 'shown in fig. 5 cut in a section containing its longitudinal center axis, wherein the height of the radially outer edge 6011' of the wall scraper 601 'close to the cylinder 201 is greater than the height of the radially inner edge 6012' away from the cylinder 201, so that the upper surface of the wall scraper 601 'forms an inclined angle with respect to the bottom surface thereof, so that the upper surface of the wall scraper 601' is configured to be downwardly concave and generally in the shape of a truncated cone as a whole. Thus, when the sludge on the inner wall of the barrel 201 is scraped by the wall scraper 601', the scraped sludge can fall into the barrel 201 along the inclined upper surface of the wall scraper 601' and then be discharged from the discharge port 4 without accumulating at the upper surface of the wall scraper 601 '.

in a not shown embodiment of the invention, the scraper can be arranged obliquely with respect to the actuating rod, i.e. the scraper is arranged non-perpendicularly to the actuating rod, i.e. the angle between the scraper and the actuating rod is not 90 degrees. This inclined arrangement of the wall scraper with respect to the actuating rod further facilitates scraping off of sludge sticking to the inner wall of the barrel 201 by the wall scraper. In another embodiment of the invention, not shown, the shaft 201 can also rotate relative to the upper cover 203 and/or the base 202, so that the wall scraper has not only a linear movement along the longitudinal central axis of the shaft 201 but also a rotational movement along the circumferential direction of the shaft 201 relative to the shaft 201, thereby enabling the sludge removing device to more effectively scrape off the sludge. In yet another embodiment of the present invention, not shown, the barrel of the vertical sludge crusher may have a polygonal cross-section such that the barrel has the shape of a hollow polygonal barrel, and at least one actuating rod and at least one wall scraper are provided corresponding to each side wall of the hollow polygonal barrel shape. In a further embodiment of the invention, not shown, the power input members on each actuating lever of the silt removing apparatus may have different gear ratios with the corresponding power output members of the transmission, thereby allowing each actuating lever to have different rotational speeds. This is particularly useful in the case of wall scrapers consisting of a plurality of segments, so that scraping can be carried out with different displacement speeds set for different segments depending on the sludge adhesion situation in the cylinder. In addition, in order to provide different sections of the wall scraper with different moving speeds, it is also possible to provide each actuating rod (and the corresponding threaded hole in the corresponding section) with a different thread configuration (for example thread pitch, etc.).

In a further embodiment of the invention, which is not shown, at least one opening or passage for the admission of high-pressure gas into the interior of the shaft can also be provided in the housing of the vertical sludge crusher, either along the inner wall edge of the shaft or in the vicinity of the inner wall of the shaft at the edge of the upper cover, said opening or passage being connected to the compressed gas device by means of a corresponding line. When the compressed gas device is activated, high-pressure gas is introduced into the shaft through the at least one opening or passage via the line, so that sludge adhering to the inner wall of the housing can be blown away by the high-pressure gas and can also contribute to preventing sludge from adhering to the inner wall of the housing.

FIG. 7 illustrates a flow diagram of one embodiment of a method of performing sludge mass fragmentation using the vertical sludge crusher shown in FIG. 1. As shown, a method 700 for sludge crushing using a vertical sludge crusher 1 according to the present invention may comprise the steps of: in step 701, the rotating shaft 501 of the vertical sludge crusher 1 is driven to rotate via a suitable power device, thereby rotating the crushing chain 502 connected to the rotating shaft 501; in step 702, the sludge block is input into the vertical sludge crusher 1 from the feed port 3 so as to be crushed by the crushing chain 502; in step 703, the sludge removing device 6 is activated to scrape off sludge adhering to the inner wall of the barrel 201 according to a certain setting (e.g., at certain time intervals), for example, during the sludge crushing process by the vertical sludge crusher 1; in step 704, when the sludge crushing is completed, the feeding of the sludge block from the feeding port 3 is stopped, and then the rotation shaft 501 is stopped; in step 705, the desliming device 6 is stopped.

It should be noted that the above steps of the method 700 do not necessarily have to be executed in the above order, and the steps are not necessarily executed only once. Also, the operation of scraping off the sludge adhered to the inner wall of the barrel 201 (e.g., the above-described step 703) does not necessarily have to be performed during the crushing of the sludge by the vertical sludge crusher 1. It is easily recognized that the scraping operation of the sludge adhered to the inner wall of the barrel 201 can be performed when the vertical sludge crusher 1 does not crush the sludge, as needed.

When the vertical sludge crusher and the operation method are adopted, the independent power device is adopted by the sludge removing device, and the power device is not shared with the rotating shaft of the vertical sludge crusher, so that the vertical sliding of the wall scraper along the straight line can be independently controlled, the abrasion or the damage caused by the high-speed rotation of the wall scraper of the sludge removing device can be effectively avoided, and the vertical sliding speed of the wall scraper along the straight line is low, so that the sludge adhered to the inner wall of the shell can be slowly scraped at a single time, the side effect of stirring the sludge is avoided, the condition that the sludge is more stirred and more adhered is avoided, and the adhesion of the sludge on the inner wall of the shell is reduced. Meanwhile, the gap between the wall scraper and the inner wall of the shell of the sludge removing device is small, so that the thickness of sludge adhered to the wall of the shell is reduced, and the sludge is prevented from being agglomerated in the gap.

The vertical sludge crusher is suitable for crushing dewatered sludge cakes or dried sludge blocks or hard blocks. Due to the characteristic property that the sludge is more viscous when being stirred or more viscous when being scraped, the sludge removing device can effectively prevent the sludge from being stirred in the crushing process in the crusher, thereby overcoming the characteristic that the sludge is more viscous when being stirred and preventing the sludge or dust from being more viscous. Of course, the skilled person can also apply the solution according to the invention to the crushing of sludges of different sludge qualities or different water contents.
