referring to fig. 1 to 5, the fertilizer-storing ceramsite preparation apparatus in the preferred embodiment of the present invention includes a preparation cylinder 1, a bearing table 2, and a first motor 3 and a second motor 4, which are correspondingly disposed at two ends of the preparation cylinder 1. The preparation cylinder 1 is designed horizontally, namely, the axis of the preparation cylinder is horizontal, the preparation cylinder 1 comprises a first cylinder 101 and a second cylinder 102 which are coaxially arranged, and the second cylinder 102 is embedded in the first cylinder 101 and can rotate relatively in the first cylinder 101.

Specifically, the first cylinder 101 in the preferred embodiment is a cylindrical structure with both closed ends, and is horizontally arranged (the term "horizontal" means that the axis of the first cylinder 101 is horizontal or approximately horizontal), and a through groove with a certain width is axially formed in the outer circumferential wall surface, and a filter screen 106 is arranged in the through groove for filtering the fertilizer solution and the fertilizer particles. In order to avoid interference caused by rotation of the filter 106 between the first cylinder 101 and the second cylinder 102, the filter in the preferred embodiment preferably does not protrude from the inner and outer circumferential walls of the first cylinder 101, i.e. the filter 106 can be obtained by forming a plurality of through holes at intervals on the cylinder of the first cylinder 101.

It can be understood that the filter screen 106 is provided with a plurality of through holes, and the inner diameters of the through holes are smaller than the outer diameter of the light ceramsite, in the actual preparation process, the outer diameter of the light ceramsite is usually 20-30 mm, and therefore, when the filter screen 106 is actually arranged, the inner diameters of the through holes are controlled to be 1-5 mm, so that the light ceramsite is prevented from being embedded and clamped in the through holes, and the damage of the light ceramsite is reduced.

Further, a first feeding hole 103 is formed in the side, opposite to the filter screen 106, of the first cylinder 101, and is used for feeding the light ceramsite; preferably, a liquid inlet 104 and a second inlet 105 are also provided on the first barrel 101, the former is used for feeding water and fertilizer solution, and the latter is used for feeding dry fertilizer. In practice, the first inlet 103 is preferably disposed in the middle of the first cylinder 101, and the second inlet 105 and the inlet 104 are disposed on both axial sides of the first inlet 103, as shown in FIG. 2.

Further, the second cylinder 102 is embedded in the first cylinder 101, is coaxial with the first cylinder 101, and has a side opening, and has a "semi-cylindrical" structure as a whole, as shown in fig. 4 and 5. Meanwhile, the two ends of the first cylinder 101 and the second cylinder 102 are respectively provided with an end plate, so that the two ends of the two cylinders can be respectively sealed by the end plates, and the arrangement of the end plates is also convenient for the arrangement of the rotating shafts at the two ends of the two cylinders.

Specifically, in the preferred embodiment, the first motor 3 is disposed on one side thereof corresponding to the rotation of the first cylinder 101, and an output shaft (i.e., the first rotating shaft 301) thereof is disposed horizontally and fixedly connected to an end plate on one side of the first cylinder 101 at an end portion thereof. Meanwhile, the end of the first rotating shaft 301 passes through the end plate of the first cylinder 101 and is rotationally matched with the end plate of the second cylinder 102, as shown in fig. 8. In actual arrangement, the first rotating shaft 301 is rotatably matched with the end plate of the second cylinder 102 by the first bearing 303, so that the second cylinder 102 can rotate around the first cylinder 101.

Further, a second rotating shaft 302 is coaxially arranged on the other end plate of the first cylinder 101, one end of the second rotating shaft 302 is fixedly connected to the end plate of the first cylinder 101, and the other end is rotatably matched with the supporting column 9 on one side. Specifically, the second rotating shaft 302 is matched with the supporting column 9 through the second bearing 304, so that the first barrel 101 can rotate around the shaft under the driving of the first motor 3. Meanwhile, in order to facilitate the arrangement of the third rotating shaft 401, the second rotating shaft 302 in the preferred embodiment is an internal hollow structure, and a through hole communicated with the hollow structure is formed on an end plate of the first cylinder 101.

Accordingly, a second motor 4 is disposed at one side of the supporting column 9, and an output shaft (i.e., the third rotating shaft 401) thereof is disposed coaxially with the second rotating shaft 302 and is connected to an end plate of the second cylinder 102 after coaxially passing through a through hole at the middle of the second rotating shaft 302, as shown in fig. 9, so that the second cylinder 102 can be driven by the second motor 4 to rotate around the shaft. In the preferred embodiment, the first motor 3, the second motor 4 are both fixed to the ground by a base, as shown in fig. 2.

In order to ensure the stability of the setting and operation of the preparation cylinder 1, a bearing platform 2, preferably a cement concrete structure, is arranged corresponding to the preparation cylinder 1, and the top of the bearing platform is provided with a semi-cylindrical accommodating groove along the length direction of the preparation cylinder 1 for embedding the bottom of the first cylinder 101, as shown in fig. 4. The inner diameter of the receiving groove is preferably the same as the outer diameter of the first cylinder 101 so that the first cylinder 101 can be accurately placed in the receiving groove. Of course, in order to assist the rotation and support of the first cylinder 101, in a preferred embodiment, a plurality of rollers or balls (not shown) may be disposed at intervals on the inner circumferential wall surface of the accommodating recess, so that the first cylinder 101 may be supported on the rollers or balls, the friction between the outer circumferential wall surface of the first cylinder 101 and the inner circumferential wall surface of the accommodating recess is reduced, and the driving force of the first motor 101 is reduced.

Furthermore, a leakage groove 107 is formed in the bottom of the accommodating groove and is used for aligning with the filter screen 106 or the first feed port 103, and then discharging of corresponding materials is achieved. During actual setting, the inner wall of the leakage groove 107 is arc-shaped, so that rapid blanking of corresponding materials is realized, and accumulation of the materials is avoided. Meanwhile, the middle part of the leakage groove 107 is provided with a leakage opening with a certain depth, and the height of the inner wall surface of the leakage groove 107 is sequentially increased from the leakage opening to the periphery, so that corresponding materials can automatically move towards the leakage opening under the action of gravity.

Meanwhile, the bottom of the material leakage opening is provided with at least two discharge openings, namely a first discharge opening 108 and a second discharge opening 109, which are respectively used for discharging the fertilizer storage ceramsite and the liquid fertilizer solution. In order to ensure the independent discharge of the two discharge ports, the end parts of the two discharge ports connected with the material leakage port are respectively provided with a valve 110 for realizing the open-close control of the corresponding discharge port. Preferably, in order to avoid the accumulation of the fertilizer-storing ceramsite at the bottom of the discharge opening, the bottom surface of the discharge opening is preferably arranged in an inclined manner in the preferred embodiment, so that the horizontal height of the part of the discharge opening connected with the first discharge opening 108 is ensured to be the lowest, and the automatic discharge of the fertilizer-storing ceramsite in the discharge opening is realized. Of course, it is understood that the arrangement heights of the first discharge hole 108 and the second discharge hole 109 are sequentially decreased from one end to the other end of the drain hole, as shown in fig. 4. In addition, in order to avoid accumulation of water and fertilizer in the material leakage port, a plurality of liquid discharge pipes 111 are obliquely downwards arranged on the bottom surface of one side of the port of the second material outlet 108, and the other ends of the liquid discharge pipes 111 departing from the second material outlet 108 are preferably communicated with the second material outlet 109 for accumulation of water and fertilizer caused by inclined arrangement of the bottom of the material leakage port.

In order to realize the automatic feeding of the materials in the preparation cylinder 1, a ceramsite feeding component 5, a fertilizer feeding component 6 and an aqueous liquid feeding component 7 are further arranged corresponding to the preparation cylinder 1 in the preferred embodiment, as shown in fig. 1. Wherein, haydite loading component 5 passes through haydite feeder 501 and communicates first feed inlet 103 for light haydite in the haydite loading component 5 can be through first feed inlet 103 accurate feeding to in preparation section of thick bamboo 1, and in the actual setting, haydite feeder 501 preferably sets up to the telescopic form, and its tip preferably sets up to the arc structure, makes this haydite feeder 501 extend after can just butt the periphery wall of first barrel 101 and seal first feed inlet 103. Meanwhile, a feeding pipe 601 is arranged on the fertilizer feeding assembly 6, and the end of the feeding pipe 601 is provided with a telescopic port, so that the end of the feeding pipe 601 can extend into the first cylinder 101 by extension after being aligned with the second feeding hole 105, thereby realizing the feeding of fertilizer. In addition, a liquid inlet pipe 701 is arranged on the liquid feeding assembly 7, and the liquid inlet pipe 701 can correspondingly extend into the liquid inlet 104 and fill the preparation cylinder 1 with a fertilizer saturated solution.

For the fertilizer storage ceramsite preparation device in the preferred embodiment, the process for preparing the fertilizer storage ceramsite preferably comprises the following steps:

(1) the preparation device is controlled to be in an initial state, at this time, the second cylinder 102 is located at the bottom of the first cylinder 101, and the first feed port 103 of the first cylinder 101 faces upward, that is, the filter screen 106 is located at the bottom of the second cylinder 102. Meanwhile, a fertilizer saturated solution is prepared in the water liquid feeding assembly 7 and is injected into the second cylinder 102 through the liquid inlet pipe 701.

In a preferred embodiment, the fertilizer in the saturated solution of fertilizer includes, but is not limited to, a nitrogenous fertilizer, a phosphate fertilizer, or a potash fertilizer.

(2) The ceramsite feeder 501 is controlled to match the first feeding hole 103, so that the lightweight ceramsite in the ceramsite feeding assembly 5 can be continuously conveyed into the second cylinder 102. Because the fertilizer saturated solution is injected into the second cylinder 102 in advance, the feeding of the light ceramsite can be buffered, and the collision damage of the light ceramsite is avoided.

In the actual feeding process, the feeding height of the light ceramsite in the second cylinder 102 does not exceed the height of the two side edges of the second cylinder 102, i.e. the light ceramsite does not contact the wall surface of the first cylinder 101 when being fed. Meanwhile, the liquid level height of the fertilizer saturated solution is not lower than the top surface height of the light ceramsite, namely all the light ceramsite is soaked in the fertilizer saturated solution.

(3) Standing for a certain time to enable the light ceramsite to fully absorb the fertilizer saturated solution, wherein at the initial stage of the soaking process, the liquid level in the second cylinder 102 is continuously reduced along with the progress of the soaking process, and at this time, the water liquid feeding assembly 7 is controlled to continuously feed the fertilizer saturated solution until the liquid level in the second cylinder 102 is not reduced any more within a certain time (usually 5-10 min). And then, continuously soaking for a certain time (at least 1 h) to ensure that each light ceramsite can fully absorb the fertilizer.

(4) After soaking, the first motor 3 is controlled to continue to maintain the locked state, the second motor 4 is controlled to work, the valve 110 on the first discharge port 108 is closed, and the valve 110 on the second discharge port 109 is opened. Afterwards, the third rotating shaft 401 drives the second cylinder 102 to rotate to the top of the first cylinder 101, as shown in fig. 6, at this time, both the light ceramsite and the fertilizer saturated solution in the second cylinder 102 enter the bottom of the first cylinder 101, and the fertilizer saturated solution is filtered by the filter screen 106.

The fertilizer saturated solution passing through the filter screen 106 enters the recovery tank through the leak tank 107 and the second discharge port 109, and can enter the water liquid feeding assembly 7 for recovery and reuse after being filtered again. Preferably, in the actual operation process, in order to improve the filtering efficiency of the light ceramsite, the first motor 3 may be controlled to swing the first cylinder 101 in a forward and reverse direction at a certain angle, so as to sufficiently improve the filtering efficiency and quality of the fertilizer saturated solution.

(5) The position of the first cylinder 101 is locked by the first motor 3, and then the second motor 4 is controlled to work, so that the second cylinder 102 can be rotated back to the bottom of the first cylinder 101 under the driving of the third rotating shaft 401, and the filtered light ceramsite can enter the second cylinder 102 again.

(6) The first motor 3 and the second motor 4 are locked respectively, so that the second barrel 102 is just at the bottom of the first barrel 101, and the second feeding hole 105 on the first barrel 101 is just aligned with the end of the feeding pipe of the fertilizer feeding assembly 6. Dry fertilizer is fed into the second barrel 102 through the feed pipe 601. In order to ensure the accuracy of the dry fertilizer in the introduction, the second feed opening 105 in the preferred embodiment may be a plurality of openings spaced axially apart, and accordingly, the dry fertilizer may be fed simultaneously from the plurality of second feed openings 105.

In addition, in order to ensure the effective dispersion of the introduced dry fertilizer, the third rotating shaft 401 of the second motor 4 is controlled to rotate during and after the fertilizer is injected, so that the second cylinder 102 swings within a certain angle in the positive and negative directions, and the light ceramsite can be ensured to be fully contacted with the dry fertilizer. When the swing control of the second cylinder 102 is performed, the first cylinder 101 may be controlled to swing synchronously. Through the existence of the hydraulic pressure difference inside and outside the light ceramsite, the moisture in the light ceramsite can be sucked out by the dry fertilizer on the surface of the light ceramsite, and the fertilizer in the saturated solution sucked by the light ceramsite is separated out in the internal gap of the light ceramsite, so that the preparation of the fertilizer storage ceramsite is realized; meanwhile, the dry fertilizer absorbs water on the surface of the light ceramsite, so that the dry fertilizer can be tightly attached to the surface of the light ceramsite to block holes of the light ceramsite, prevent the fertilizer in the light ceramsite from running out, and increase the fertilizer carrying capacity of the fertilizer storage ceramsite. In practice, the above process lasts no less than 30 min.

(7) After the fertilizer storage ceramsite is fully contacted with the dry fertilizer, the moisture in the fertilizer storage ceramsite is fully absorbed, at the moment, the third rotating shaft 401 is controlled to rotate, the second cylinder 102 is rotated to the top of the first cylinder 101, and the fertilizer storage ceramsite falls into the upper part of the filter screen 106. Thereafter, the position of the second barrel 102 is locked, the first barrel 101 is controlled to swing within a certain angle, so that fertilizer particles in the first barrel 101 are screened, the fertilizer is screened into the leakage groove 107, and the fertilizer storage ceramsite is separated from the fertilizer.

In order to avoid the fertilizer from accumulating in the leaking groove 107, in a preferred embodiment, a plurality of flushing holes (not shown in the figure) communicated with the leaking groove 107 are formed in the outer peripheral wall surface of the bearing platform 2, so that the fertilizer in the leaking groove 107 can be flushed away by high-pressure water flow, and enters the recovery tank through the second discharge port 109, and then is recovered and reused for preparing the fertilizer saturated solution. Certainly, in order to perform the inside of the first cylinder 101 in the water body when the wall surface is flushed by the high-pressure water flow, the third rotating shaft 401 may be controlled to rotate the second cylinder 102 to the bottom of the first cylinder 101, so that the dried fertilizer-storing ceramsite may be stored in the second cylinder 102, and the filter screen 106 is blocked by the second cylinder 102.

(8) Closing the valve 110 on the second discharge port 109, opening the valve 110 on the first discharge port 108, controlling the first cylinder 101 and the second cylinder 102 to rotate synchronously, so that the second cylinder 102 rotates to the top of the first cylinder 101, and the first feed port 103 is aligned with the leakage groove 107, so that the dried fertilizer-storing ceramsite in the first cylinder 101 sequentially falls into the leakage groove 107, and the discharge is completed through the first discharge port 108.

In order to avoid the fertilizer-storing ceramsite from being retained in the first cylinder 101, in a preferred embodiment, a wedge-shaped groove is formed on the inner circumferential wall surface of the cylinder near the first feeding hole 103, as shown in fig. 4 and 5, so that the inner circumferential surface of the first cylinder 101 obliquely extends to the first feeding hole 103, and the fertilizer-storing ceramsite can automatically fall into the leakage groove 107 under the action of self weight. In addition, in order to improve the efficiency of discharging the fertilizer storage ceramsite, the first cylinder 101 can be controlled by the first motor 3 to swing at a small angle during discharging until all the fertilizer storage ceramsite is discharged.

The preparation device for the fertilizer-storing ceramsite, provided by the invention, has the advantages of simple structure, simplicity and convenience in arrangement, capability of continuously realizing batch preparation of the fertilizer-storing ceramsite, high automation degree, capability of greatly improving the preparation efficiency of the fertilizer-storing ceramsite, reduction in the breakage rate in the preparation process of the fertilizer-storing ceramsite, increase in the fertilizer-carrying capacity of the fertilizer-storing ceramsite, improvement in the service performance of the fertilizer-storing ceramsite, reduction in the use cost of the fertilizer-storing ceramsite, and good application prospect and popularization prospect.

It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
