As shown in fig. 1 to 5, the present invention provides a mobile flow conductor oxidation treatment line, in particular to a mobile flow conductor oxidation treatment line for treating oxidized pipes by using flow conductors, and further relates to a mobile flow conductor oxidation treatment line for treating oxidized pipes by using flowing liquid. The movable type flowing conductor oxidation treatment production line comprises a feeding device and a treatment device, wherein the feeding device is used for feeding the treatment device, the treatment device comprises a treatment cabin 1, the bottom of the treatment cabin 1 is provided with a movable type footing 2, the side wall of an inner cavity of the treatment cabin 1 is provided with two parallel limiting rollers 3 through a bearing, the side wall of the inner cavity of the treatment cabin 1 is provided with two parallel bearing rollers 4 through a bearing, the two bearing rollers 4 are positioned below the area between the two parallel limiting rollers 3, a liquid cabin 5 is fixed on the outer side wall of the treatment cabin 1, a rust removing liquid 6 is arranged in the liquid cabin 5, two ends of the liquid cabin 5 are connected with flow guide intervention pipes 7 which penetrate into the treatment cabin 1 from two ends of the treatment cabin 1, each flow guide intervention pipe 7 is slidably sleeved with a clamping seat 8 positioned in the treatment cabin 1, for example, the flow guide intervention pipes 7 are used for supporting and guiding the clamping seats 8, and a circulating pump 9 is fixed in the liquid cabin 5, the inlet and outlet of the circulating pump 9 are respectively connected to the two flow guide intervening pipes 7, the two ends of the limiting roller 3 are respectively provided with a driving wheel 10, and the two driving wheels 10 are respectively adjacent to the two clamping seats 8.

For example, the peripheral surface of the drive wheel 10 is slidably abutted against the peripheral surface of the holder 8. The circumferential surface of the driving wheel 10 is provided with a wedge seat 11 capable of rotating along with the driving wheel, the end surface of the clamping seat 8 is provided with a wedge block 12 matched with the wedge seat 11, the driving wheel 10 drives the wedge seat 11 to rotate to be in contact with the wedge block 12, the clamping seat 8 is driven by the wedge block 12 to drive the pipe fitting to move along the axial direction of the bearing roller 4, a tension spring 13 is connected between each clamping seat 8 and the end surface of the inner cavity of the treatment cabin 1, when the driving wheel 10 drives the wedge seat 11 to be separated from the wedge block 12, the clamping seat 8 is pulled by the tension spring 13 to return along the axial direction of the flow guide intervention pipe 7, and therefore the pipe fitting is driven to move back and forth. For example, the treatment tank 1 and the liquid tank 5 located on the side wall of the treatment tank are both provided with a rust removing liquid.

For example, the two carrier rollers 4 are parallel to the two stopper rollers 3, respectively. For example, in one embodiment, rollers (not shown) are provided in the movable foot 2, and the rollers can be folded therein. The tail end of each flow guide intervention pipe 7 is provided with a flushing outlet, the flushing outlets of the two flow guide intervention pipes 7 are arranged oppositely, and the two clamping seats 8 are used for blocking the two opposite ends of the pipe fitting respectively so that the end parts of the two flow guide intervention pipes 7 are inserted into the two opposite ends of the inner cavity of the pipe fitting respectively. The two bearing rollers 4 are used for supporting two sides of the bottom of the pipe fitting, and the two limiting rollers 3 are respectively used for abutting against two opposite side walls of the pipe fitting so that the pipe fitting is parallel to the bearing rollers 4. The circumferential surface of the limiting roller 3 is provided with a spiral propelling structure 14. The spiral propelling mechanism 14 is used for rotating the peripheral surface of the friction pipe fitting, and the arrangement of the spiral propelling mechanism 14 can ensure that when the spiral propelling mechanism rotates along with the limiting roller 3, the derusting liquid in the treatment cabin 1 is turned to generate a wave making effect, and the rust on the peripheral surface of the pipe fitting is scraped, so that the scale of a rust layer removed from the outer wall surface of the pipe fitting after the pipe fitting is soaked in the treatment cabin 1 falls downwards.

In the present embodiment: the treatment cabin 1 is filled with rust removing liquid (capable of conducting electricity), opposite ends of the oxidized and rusted pipe fitting are respectively clamped between the two clamping seats 8, two bearing rollers 4 are used for bearing two sides of the bottom of the pipe fitting, and two limiting rollers 3 are used for limiting.

Then, after the circulating pump 9 is powered on and started, the rust removing liquid in the treatment cabin 1 and the rust removing liquid in the liquid cabin 5 form a liquid supply circulation (namely a liquid flow loop is formed) by utilizing the two flow guide intervening pipes 7, wherein the rust removing liquid flowing through the flow guide intervening pipes 7 flows in the pipe cavity of the pipe fitting, if the inner wall of the pipe cavity of the pipe fitting is corroded, the rust removing liquid can soak the corrosion in the pipe cavity, and when the rust removing liquid flows in the pipe cavity, the impact speed of the rust removing liquid can bring the fallen corrosion into the liquid cabin 5 through the flow guide intervening pipes 7, and the pipe fitting is filtered by a filter on the circulating pump 9, so that when the pipe fitting is soaked in the treatment cabin 1, the corrosion in the pipe cavity can be cleaned except that the corrosion on the outer wall of the pipe fitting is soaked and fallen, and the rust removing efficiency of the pipe fitting is high.

For example, optionally, flow guide eduction tubes are further disposed at two opposite ends of the liquid tank 5, and the flow guide eduction tubes are flexible tubes and used for leading out the flowing conductive rust removing liquid and directly injecting the flowing conductive rust removing liquid into an inner cavity of a pipe fitting of the high-power radio-frequency signal transmitter, so that the high-power radio-frequency signal transmitter can also perform rust removing operation in a working state without dismantling/shutting down.

For example, two flow conduits 7, the tank 5 and the treatment tank 1 form a liquid flow circuit. The outer wall of one end of the processing cabin 1 is provided with a gear box 15 which is in transmission connection with the bearing roller 4 and the limiting roller 3, the gear box 15 is provided with a motor 16 which is in transmission connection with a gear mechanism in the gear box 15, and the motor 16 is used for driving the limiting roller 3 and the bearing roller 4 to rotate through the gear box 15. Bearing blocks 17 are arranged on one opposite sides of the two clamping seats 8, a circle of spring pieces 18 are arranged on the circumferential surface of each bearing block 17, a fixing hole 27 is formed in each spring piece 18, a brush rod 28 is fixedly mounted on each spring piece 18 through the fixing holes 27 and screws, the brush rods 28 are parallel to the limiting rollers 3, and the brush rods 28 are used for being inserted into the pipe fitting and abutting against the circumferential surface of the inner wall of the pipe fitting, so that the pipe fitting is positioned by the aid of the two clamping seats 8.

For example, in one embodiment, optionally, only one wedge block 11 is provided on each drive wheel 10 adjacent the gear box 15 and only one wedge block 12 is provided on each clamp seat 8 adjacent the gear box 15 so as not to interfere with the reciprocating movement of the tubulars.

For example, the wedge seat 11 and the wedge 12 may be engaged with each other in a manner that drives the holder 8 to move along the axial direction of the bearing shaft 4, for example, a first inclined surface is formed on the wedge seat 11, a second inclined surface is formed on the wedge 12, and the first inclined surface is in sliding fit with the second inclined surface until the wedge seat 11 passes over the wedge 12 from an end of the wedge 12 away from the holder 8, so that the xixing arm 11 and the wedge 12 are disengaged from each other.

For example, in actual use, the motor 16 can be started to make the bearing roller 4 and the limiting roller 3 which are connected together by the transmission of the gear box 15 rotate synchronously, the two bearing rollers 4 rotate, because the inner wall surface of the clamping seat 8 is provided with the bearing seat 17, and the outer wall surface of the bearing seat 17 is provided with the circle of spring pieces 18, when the pipe fitting is installed, the bearing seat 17 can allow the pipe fitting to rotate, and after the pipe fitting is installed, the outer wall of the pipe fitting can be in contact with and supported on the bearing roller 4, so the bearing roller 4 and the limiting roller 3 rotate, the pipe fitting can be driven to rotate, the pipe fitting can be soaked in the treatment cabin 1 for cleaning, the rust layer on the outer wall surface of the pipe fitting can be ground downwards when the pipe fitting rotates, when the limiting roller 3 rotates, the wedge seat 11 on the driving wheel 10 can be frequently in contact with and separated from the wedge 12 on the clamping seat 8, so that the wedge 12 pushes the clamping seat 8 to move back and forth on the flow guide pipe 7, therefore, the pipe fitting clamped between the two clamping seats 8 can move back and forth on the outer wall surfaces of the two bearing rollers 4, and the purposes of polishing in a self-rotating mode and polishing in a displacement mode are achieved.

Specifically, the spring plate 18 is provided with the fixing hole 27, the spring plate 18 is provided with the brush rod 28 extending towards the length direction of the treatment cabin 1 through the fixing hole 27 and the screw, so that after the pipe is clamped between the two clamping seats 8, the brush rod 28 just extends into the pipe cavity of the pipe, and the pipe can rotate to a certain extent under the rotation action of the bearing roller 4, so that the rust layer in the inner cavity of the pipe can be cleaned by the brush rod 28 when the pipe rotates, and the rust layer in the pipe cavity of the pipe can be cleaned by the flowing rust removing liquid in a soaking manner, and can also be cleaned by the brush rod 28 directly in a grinding manner, so that the working efficiency is improved.

For example, a plurality of liquid inlet holes 19 are formed in the circumferential surface of one end of each flow guide intervening pipe 7, which is adjacent to the clamp base 8, the liquid inlet holes 19 are positioned in the treatment chamber 1, so that the rust removing liquid in the treatment chamber 1 can enter the flow guide intervening pipe 7 through the liquid inlet holes 19, and can also circulate into the liquid chamber 5 through the flow guide intervening pipe 7 to form circulation operation, and as the circulating pump 9 in the liquid chamber 5 is provided with a filtering structure such as a filter screen or a filter, the scale impurities in the rust removing liquid are filtered and then recycled into the treatment chamber 1, and the structure is reasonable.

For example, the carrier roller 4 includes a grinding wheel roller body 21 and support shafts 20 formed at opposite ends of the grinding wheel roller body 21, the diameter of each support shaft 20 is smaller than that of the grinding wheel roller body 21, ends of the two support shafts 20 are rotatably mounted on wall surfaces at two ends of an inner cavity of the processing chamber 1, a grinding wheel surface is formed on the circumferential surface of the grinding wheel roller body 21, and the grinding wheel surface 21 forms a grinding contact surface of a rust layer on the outer wall surface of the pipe fitting, so that the structure is reasonable.

For example, a cavity structure is formed on one side of each of the two opposite holders 8, each bearing seat 17 is located in the corresponding cavity structure of the holder 8, arc-shaped concave surfaces 26 are respectively disposed on two sides of the bottom of the holder 8, the two arc-shaped concave surfaces 26 of each of the holders 8 respectively slidably abut against the support shafts 20 of the two carrier rollers 4, balls 28 are mounted on outer wall surfaces of the arc-shaped concave surfaces 26, the balls 28 rollingly abut against the circumferential surfaces of the support shafts 20, and the holder 8 which is displaced back and forth along the carrier rollers 4 can be stably guided by the support shafts 20 and the balls 28, wherein the balls 28 are arranged to prevent the carrier rollers 4 from being obstructed when the carrier rollers 4 rotate, that is, when the holder 8 is displaced on the carrier rollers 4, the balls 28 can rotate universally, and smooth guiding of the holder 8 through displacement of the carrier rollers 4 is ensured.

Furthermore, the clamping seat 8 is circular, a plurality of through holes are formed in the clamping seat 8, and a retaining ring is formed on the circumferential surface of the clamping seat 8 and used for retaining the end face periphery of the pipe fitting.

For example, to facilitate the reciprocating movement of the tubular, in one embodiment, optionally, a slip-off prevention ring is provided in the cavity structure of the holder 8 adjacent to one end of the gear housing 15 for rotatably mounting the end of the tubular and preventing the tubular from axially slipping off the slip-off prevention ring. The end surface of the pipe fitting is provided with a ring groove, and the anti-release ring is clamped in the ring groove in a sliding manner. The distance between the two holders 8 is greater than the length of the pipe. The wedge blocks 12 on the holder 8 at the end far from the gear box 15 are smaller than the wedge blocks 12 on the holder 8 at the end near the gear box 15, and the wedge blocks 12 on the driving wheel 10 at the end far from the gear box 15 are smaller than the wedge blocks 11 on the driving wheel 10 at the end near the gear box 15, so that when the holder 8 near the gear box 15 drives the pipe to move integrally, the other holder 8 drives the brush rod 28 to move axially relative to the pipe, so as to shorten the distance between the two holders 8. When the two clamping seats 8 are respectively about to abut against the two opposite ends of the pipe fitting, the wedge block 12 is released by the wedge seat 11, and the two clamping seats 8 are far away from each other. Namely, one of the clamping seats 8 drives the pipe fitting to move back and forth integrally, while the other clamping seat 8 is driven by the brush rods 28 to move axially relative to the pipe fitting synchronously, and the brush rods 28 are utilized to clean the structure on the inner side of the pipe fitting.

For example, referring to fig. 6, oxidation is more likely to occur in the end of the pipe far from the gear box 15 due to structural reasons, in order to improve the cleaning effect, a ferrule 101 is fixedly mounted at the end of the brush rods 28 on the holder 8 far from one end of the gear box 15, a plurality of extension rods 102 are protruded from the periphery of the ferrule 101, a spiral ferrule 103 is fixedly disposed in the region surrounded by the extension rods 102, a spiral pipe 105 is coaxially fixed at the end of the diversion intervention pipe 7 on the holder 8, a flushing outlet is communicated with the inner cavity of the spiral pipe 105, a spiral guide rib is formed on the outer peripheral surface of the spiral pipe 105, a spiral groove is formed in the spiral ferrule 103, and the spiral ferrule 103 is sleeved on the spiral pipe 105 so that the spiral guide rib is slidably fitted in the spiral groove. Since the bearing seat 17 allows the plurality of brush rods 28 to rotate relative to the holder 8, that is, the rotation of the holder 8 may not drive the brush rods 28 to rotate, in the present case, in the process that the holder 8 drives the plurality of brush rods 28 to move forward relative to the diversion intervention tube 7, the spiral tube 105 drives the spiral ring 103 to rotate so as to drive the plurality of extension rods 102 and the plurality of vertical rods 18 to rotate relative to the tube, the rotation direction of the extension rods 102 is opposite to the rotation direction of the tube, and the extension rods 102 circumferentially rub the inner cavity of the tube while axially moving relative to the tube, thereby improving the cleaning effect.

The above-described embodiments further explain the object, technical means, and advantageous effects of the present invention in detail. It should be understood that the above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. It should be understood that any modifications, equivalents, improvements and the like, which come within the spirit and principle of the invention, may occur to those skilled in the art and are intended to be included within the scope of the invention.
