Description

Technical Field

[0001] The present invention relates to the technical field of lead-acid battery recycling, and in particular to a lead-acid battery recycling sorting device. Background Art

[0002] Lead-acid battery recycling is a rigorous and vital environmental protection task, which aims to safely handle harmful substances (mainly lead and sulfuric acid) in waste batteries and maximize the recovery of valuable materials (lead, plastic, sodium sulfate, etc.). After the discharge and crushing process, the product is immediately transported to the hydraulic sorting process, and the density difference of different components is used for separation. Lead and lead paste have the largest density and sink to the bottom, while plastic (polypropylene shell, partition) has a smaller density and floats on the water surface. The waste acid (sulfuric acid electrolyte) dissolves in the water or forms a dilute acid solution.

[0003] Chinese patent CN111716593B discloses a waste lead-acid battery plastic shell recycling system, including a sorting tank, a water pump for replenishing water in the sorting tank, a stirring mechanism and an impurity separation device arranged in the sorting tank; the impurity separation device includes a threaded rod spanning opposite sides of the sorting tank and a power unit driving the threaded rod to rotate, the two sides of the threaded rod are provided with threads of different rotation directions, and the threaded rod is threadedly connected with two push plates that can fit each other, and the push plates are used to push out impurities floating in the sorting tank; the upper side of the push plate is located above the sorting tank, and the lower side of the push plate is located in the upper part of the sorting tank and can slide along the sorting tank; the opposite side walls of the sorting tank are provided with collection frames opposite to the threaded rod.

[0004] However, this technical solution usually sets a rotating toggle plate on the water surface when collecting plastic fragments, and uses downward pressure and patting to make the lead paste attached to the plastic fragments fall off, and drive the plastic fragments to gradually move and output. However, after the used batteries are broken, the lead paste is highly adhered to the surface of the plastic shell, and the patting method is not enough to separate it. In addition, the patting force is large, which makes the water surface fluctuate greatly, which easily leads to the situation that some lead paste should have settled but is suspended and unable to settle due to the fluctuation of water flow, which leads to the output of plastic fragments carrying more lead paste. Summary of the invention

[0005] The purpose of the present invention is to provide a sorting device for lead-acid battery recovery in view of the shortcomings of the prior art. The device can fully separate plastic fragments from attached lead paste by means of a separation mechanism in cooperation with an auxiliary mechanism, thereby solving the technical problems in the prior art of poor lead paste sedimentation effect caused by only beating on the water surface and the plastic fragments easily adhering to a large amount of lead paste output.

[0006] To achieve the above object, the present invention provides the following technical solution: A sorting device for lead-acid battery recycling, comprising a sorting tank, and a separation mechanism arranged above the water surface in the sorting tank; The separation mechanism includes a conveying component arranged corresponding to the inlet position of the sorting tank, a fishing component arranged on the conveying component and on one side of the inlet position of the sorting tank, a rubbing component arranged in the sorting tank and above the conveying component, a centrifugal component arranged in the sorting tank along the conveying direction of the conveying component, and a cleaning component arranged at the outlet position of the centrifugal component; A large number of fragments after the lead-acid battery is broken enter the conical part of the sorting tank from the inlet together with the water flow.

[0012] Further, an auxiliary mechanism is further included and is disposed below the separation mechanism; The auxiliary mechanism is used to collect the paste that floats and cannot settle autonomously, and includes a drainage assembly disposed in the sorting tank and used to drive the floating paste away from the area with large fluctuations, a dredging assembly disposed on the drainage assembly and used to prevent the drainage assembly from being blocked, and a collection assembly disposed on the drainage assembly and used to collect and discharge the paste concentratedly.

[0013] Further, the drainage assembly includes a protection box connected to the sorting tank, a U-shaped pipe connected to the protection box and having a liquid inlet hole, a filter box connected to the protection box and communicating with the U-shaped pipe through a branch pipe, a filter plate connected to the filter box, a drain pipe connected to the bottom of the filter box, a fifth motor connected to the sorting tank, a propeller blade connected to the output end of the fifth motor and located inside the U-shaped pipe, a scraper connected to the sorting tank through a torsion spring member and located below the conveying assembly, and an infusion groove opened inside the scraper.

[0014] Further, the dredging assembly includes two mounting boxes connected to the U-shaped pipe, a first reciprocating lead screw connected inside the mounting box, a plurality of cleaning plates connected to the mounting box and connected to the first reciprocating lead screw, a first sealing plate connected to the cleaning plate, and a first bevel gear transmission member connected between the output end of the fifth motor and the first reciprocating lead screw.

[0015] Still further, the collection assembly includes a second reciprocating lead screw connected to the protection box and connected to the output end of the fifth motor through a second bevel gear transmission member, a rotating brush located at the center position of the filter plate and connected to the end of the second reciprocating lead screw through a third bevel gear transmission member, a sewage discharge groove opened on the filter plate and the filter box, a blocking plate connected to the filter plate, a plugging frame penetrating through the filter box and used to close the sewage discharge groove, a third spring connected between the plugging frame and the filter box, and a throttling member connected to the filter box; The intercepting member includes a second sealing plate connected to the filter box and connected with a transmission shaft, two groups of second racks connected to the second sealing plate and connected with intercepting plates, a second gear connected to the transmission shaft and meshing with the two groups of second racks, an opening and closing rack connected to the filter box and meshing with the second gear, a driving rod connected to the filter box and connected with the transmission shaft, a fourth spring connected between the driving rod and the filter box, a moving block connected to the second reciprocating lead screw, and a triangular block connected to the moving block and used to drive the plugging frame to move.

[0017] (2) By setting the centrifugal assembly in the separation mechanism of the present invention, the plastic fragments that have been rubbed and washed and immersed in water again are collected and centrifuged, and the liquid with lead paste on the fragments is removed by centrifugation, so that there is basically no lead paste residue on the surface of the plastic fragments after output, improving the recovery rate of lead raw materials.

[0018] (3) By setting the drainage assembly in the auxiliary mechanism of the present invention, the water flow is guided at both sides of the sorting pool, thereby driving some suspended lead paste to move and be collected, preventing the plastic fragments from carrying too much lead paste when output, and at the same time accelerating the sedimentation effect is also beneficial to reducing the situation of lead paste output with the solution, thereby reducing the pressure of the pressure filtration work.

[0019] (4) By setting the collection assembly in the auxiliary mechanism of the present invention, when the drainage assembly works, the larger lead paste debris is actively concentrated and collected, discharged after agglomeration to improve the sedimentation effect. At the same time, the liquid containing only tiny lead paste debris after treatment is used for the cleaning work of the conveying assembly and the centrifugal assembly, improving the utilization rate of water resources.

[0024] Embodiment 1 As Figures 1 to 2 and Figure 6 shown, this embodiment provides a sorting device for lead-acid battery recycling, including a sorting pool 100 and a separation mechanism 1 arranged above the water surface in the sorting pool 100; The separation mechanism 1 includes a conveying component 11 arranged corresponding to the inlet position of the sorting pool 100, a fishing component 12 arranged on the conveying component 11 and on one side of the inlet position of the sorting pool 100, a rubbing component 13 arranged in the sorting pool 100 and above the conveying component 11, a centrifugal component 14 arranged in the sorting pool 100 along the conveying direction of the conveying component 11, and a cleaning component 15 arranged at the outlet position of the centrifugal component 14; A large number of fragments after the lead-acid battery is broken enter the conical part of the sorting pool 100 along with the water flow from the inlet. The lead with a large self-weight quickly completes sedimentation. The remaining plastic fragments and the lead paste attached to the fragments are placed on the conveying component 11 by the fishing component 12 and conveyed forward. Under the action of the rubbing component 13, the lead paste is separated from the fragments. Then, the fragments enter the water again for cleaning from the tail end of the conveying component 11. Finally, the fragments are put into the centrifugal component 14 by a manipulator for treatment and then discharged. Subsequently, the cleaning component 15 performs the work of removing the lead paste from the inner wall of the centrifugal component 14.

[0025] In this embodiment, by setting the separation mechanism 1, the broken products are successively subjected to the processes of water washing, rubbing, water washing, and centrifugation, so that the lead paste remaining on the shredded fragments is basically removed, greatly improving the recovery rate of lead raw materials. At the same time, the pressure of subsequent plastic fragment treatment work is also reduced, preventing the pollution of lead raw materials.

[0026] Specifically, the products after the lead-acid battery passes through the crushing process enter one side inside the sorting pool 100 along with the water flow. Objects with different densities in the water start to separate. The lead quickly sinks and is collected and conveyed by the bottom spiral auger. The plastic fragments move towards the position of the transmission component. At this time, due to the different states, the lead paste is also in different positions. The lead paste attached to the plastic fragments comes to the conveying component 11 together with the plastic fragments under the action of the fishing component 12. The tiny lead paste diffuses in the liquid and mixes with the acid solution, and then is output together with the acid solution for pressure filtration work. Some relatively large lead paste debris that should have settled is suspended among the plastic fragments under the agitation of the water flow. After the plastic fragments are acted on by the rubbing component 13, they enter the solution on one side again, are simply rinsed, and then are sent to the position of the centrifugal component 14 by a manipulator. After centrifugation, the plastic fragments are discharged, and the cleaning component 15 cleans the inner wall of the centrifugal component 14. The cleaned liquid is directly discharged to the pressure filtration work position.

[0027] It should be noted that the manipulator is a prior art and will not be elaborated here.

[0028] Further, as Figures 1 to 5As shown in the figure, the conveying assembly 11 includes four groups of sliders 112 connected to the sorting tank 100 through the first springs 111, a first conveying rod 114 connected to the first motor 113 and connected to the sliders 112 on both sides, a second conveying rod 115 connected between the other two groups of sliders 112, and a conveyor belt 116 wound around the first conveying rod 114 and the second conveying rod 115.

[0029] In this embodiment, by arranging the conveying assembly 11 which is integrally supported on the slider 112, the plastic fragments can cooperate with the kneading assembly 13 to achieve a vibrating effect during the conveying process, thereby helping the plastic fragments to be kneaded on both sides and improving the separation effect.

[0030] Specifically, when the plastic fragments are placed on the conveying assembly 11 by the fishing assembly 12, the first motor 113 drives the first conveying rod 114, the second conveying rod 115 and the conveyor belt to rotate through the output end to transfer the fragments to the other side. During the process, the whole is vibrated in cooperation with the kneading assembly 13, thereby driving the fragments to turn over.

[0031] It should be noted that through the arrangement of the conveying assembly 11, the water surface is divided into three parts, which are, in sequence from the entrance, the first water washing position, the static sedimentation position and the second water washing position. A sprocket chain can also be arranged between the first conveying rod 114 and the second conveying rod 115 to enhance the transmission effect.

[0032] Furthermore, as Figures 2 to 5 shown in the figure, the fishing assembly 12 includes two groups of mounting frames 121 connected to the sliders 112 and arranged corresponding to the second conveying rod 115, a rotating tube 122 connected to the mounting frame 121 and coaxially arranged with the second conveying rod 115, a fishing frame 123 connected between the two rotating tubes 122, a rectangular ring 125 connected to the rotating tube 122 through the second spring 124, a reset rope 126 connected between the rectangular ring 125 and the mounting frame 121, an L-shaped rod 127 connected to the second conveying rod 115, and a trigger block 128 connected to the mounting frame 121 and used to drive the separation of the rectangular ring 125 and the L-shaped rod 127.

[0033] In this embodiment, by arranging the fishing assembly 12, the plastic fragments after the first water washing in the water can be fished up and separated from the liquid surface, so that the water surface will not be affected during the scrubbing, and the sedimentation work of the lead paste debris in the water is promoted.

[0034] Specifically, after the plastic debris enters the water, it continuously moves towards the position of the fishing rack 123 and reaches above the fishing rack 123. As the second transmission rod 115 drives the L-shaped rod 127 to start pushing the rectangular ring 125 to rotate, the rotating tube 122 also starts to drive the fishing rack 123 to rotate a certain angle until the plastic debris is sent onto the conveyor belt 116. At this time, under the action of the trigger block 128, the rectangular ring 125 gradually separates from the L-shaped rod 127, and then the fishing assembly 12 resets under the action of the reset rope 126 and the second spring 124. This process is repeated to send the plastic debris to the conveying assembly 11 wave by wave.

[0035] It should be noted that the side of the fishing rack 123 is fan-shaped. Therefore, during the upward flipping and resetting process, firstly, it will not press the plastic debris into the water, and secondly, it can limit the position of the plastic debris. When it rotates downward, the debris will reach above the fishing rack 123 under the push of the water flow, thereby ensuring the calm state of the water surface in the middle position. A limiting long plate can be set at the entrance to assist the plastic debris to move towards the fishing plate position.

[0036] Furthermore, as Figures 2 to 4 shown, the rubbing assembly 13 includes two sets of rotating shafts 132 arranged on both sides of the sorting pool 100 and connected by a belt transmission member 131, a second motor 133 connected to the sorting pool 100 and connected to one of the rotating shafts 132 through an output end, a rubbing plate 134 connected to the rotating shafts 132 through a rotating shaft 130, two sets of semi-tooth rings 135 connected to the sorting pool 100 and arranged corresponding to the rotating shafts 132, a T-shaped rod 136 connected to the rotating shaft 132 and arranged corresponding to the semi-tooth ring 135, an adjusting gear 137 connected to the T-shaped rod 136 and meshing with the semi-tooth ring 135 for transmission, and a synchronizing rod 138 connected to the same-side slider 112.

[0037] In this embodiment, by setting the rubbing assembly 13 to drive the rubbing plate 134 to rub on the conveying assembly 11 at a certain speed, a relative movement is generated with the plastic debris in transmission, achieving the purpose of scrubbing. At the same time, during the downward pressing process, the debris is also driven to disperse in all directions. After multiple rubbings, the debris is basically cleaned and awaits entry into the second water wash for separation.

[0038] Specifically, when the plastic fragments are being conveyed, the second motor 133 drives the kneading plate 134 to move in a circular motion to scrub the fragments. Each time the kneading plate 134 presses down, it drives the entire conveying assembly 11 to descend a certain distance, thereby increasing the contact time between the kneading plate 134 and the fragments and improving the kneading efficiency. At the same time, when the kneading plate 134 resets upward, the T-shaped rod 136 connected to the rotating shaft 132 squeezes the synchronization rod 138 on the slider 112 through a corner at the end. Driven by the synchronization rod 138, the entire conveying assembly 11 moves downward to the lowest position. As the T-shaped rod 136 reaches the lowest position, the steering gear 137 connected to the T-shaped rod 136 meshes and rotates with the semi-toothed ring 135, causing the end of the T-shaped rod 136 to rotate 90°, thereby canceling the extrusion of the synchronization rod 138. Immediately, the first spring 111 quickly drives the conveyor belt 116 to reset through its elastic force. After the slider 112 is restricted and stops, at this time, the fragments on the conveyor belt 116 separate from the conveyor belt 116 due to inertia and fall back onto the conveyor belt 116 under the action of gravity, realizing turning over.

[0039] It should be noted that there are two sets of teeth on the semi-toothed ring 135 for driving the T-shaped rod 136 to reset. Under the action of the rotating shaft 130, the kneading surface of the kneading plate 134 always remains downward.

[0040] Further, as Figure 2 and Figures 6 to 7 shown, the centrifugal assembly 14 includes two sets of covers 141 connected in the sorting tank 100, a conical centrifugal barrel 142 connected to the cover 141, a driving toothed ring 143 connected to the conical centrifugal barrel 142, a third motor 144 connected to the sorting tank 100, and a driving gear 145 connected to the output end of the third motor 144 and meshing with the driving toothed ring 143 for transmission.

[0041] In this embodiment, by setting the centrifugal assembly 14 in the separation mechanism 1, the plastic fragments that have been scrubbed and immersed in water again are collected and centrifuged. Through centrifugation, the liquid with lead paste on the fragments is removed, so that there is basically no lead paste residue on the surface of the plastic fragments after output, improving the recovery rate of lead raw materials. The setting of the two conical centrifugal barrels 142 ensures the continuity of production, provides time for cleaning, is beneficial to the recovery of lead paste and extends the service life of the equipment.

[0042] Specifically, the plastic fragments after the second water wash are alternately sent into the two conical centrifugal barrels 142 by the manipulator. Driven by the third motor 144 and the driving gear 145, the two driving toothed rings 143 drive the corresponding conical centrifugal barrels 142 to rotate. When the conical centrifugal barrel 142 containing the fragments rotates, the fragments gradually move upward along the inclined surface and are finally discharged at the outlet position of the cover 141. During the process, the liquid containing minute lead paste on the fragments is discharged from the filter holes of the conical centrifugal barrel 142.

[0043] It should be noted that the two groups of conical centrifugal barrels 142 always operate continuously. There are no filter holes at the position where the upper part of the conical centrifugal barrel 142 is connected to the driving gear ring 143 to ensure the cleanliness of the driving gear ring 143. At the same time, a protective cover is provided to cover the driving gear ring 143 and the driving gear 145.

[0044] Furthermore, as Figure 2 and Figures 6 to 7 shown, the cleaning assembly 15 includes a partition plate 151 connected to the outlet position of the conical centrifugal barrel 142, a lifting rod 152 connected to the partition plate 151, a rotating seat 153 connected to the lifting rod 152 and located at the bottom opening position of the conical centrifugal barrel 142, a fourth motor 155 connected to the sorting tank 100 and having a first gear 154 connected to its output end, two first racks 156 respectively connected to the corresponding lifting rods 152 and meshing with the first gear 154, a trigger tube 157 communicating with the partition plate 151 and having a through hole 150 opened therein, and a tee tube 158 connected to the sorting tank 100 and connected to the two trigger tubes 157.

[0045] In this embodiment, by providing the cleaning assembly 15, it is beneficial to quickly drive the relatively large-volume lead paste remaining on the inner wall of the conical centrifugal barrel 142 to be discharged from the bottom opening by the water flow, thereby ensuring the smooth progress of the centrifugation process.

[0046] Specifically, after the debris is discharged, the fourth motor 155 drives the two lifting rods 152 to complete the alternation of the upper and lower positions through the meshing of the first gear 154 and the first racks 156. When the lifting rod 152 drives the rotating seat 153 to move downward, the bottom opening of the conical centrifugal barrel 142 is opened. One of the partition plates 151 moves downward with the lifting rod 152, causing the outlet of the cover plate 141 to close. At the same time, the corresponding trigger tube 157 moves downward, and the through hole 150 opened therein communicates with the tee tube 158. The liquid filtered by the auxiliary mechanism 2 flows into the conical centrifugal barrel 142 and gradually moves downward in a spiral manner, driving the lead paste to be discharged from the bottom opening of the conical centrifugal barrel 142. At the same time, the other group starts the centrifugation work.

[0047] It should be noted that the rotating seat 153 drives the conical centrifugal barrel 142 through friction, and the water flow direction of the cleaning assembly 15 is opposite to the rotation direction of the conical centrifugal barrel 142, which is beneficial to the flushing process.

[0048] Furthermore, as Figures 1 to 2 and Figures 8 to 9 shown, it further includes an auxiliary mechanism 2 provided below the separation mechanism 1; The auxiliary mechanism 2 is used to collect the lead paste that floats and cannot settle on its own. It includes a drainage component 21 arranged in the sorting tank 100 and used to drive the floating lead paste away from the area with large fluctuations, a dredging component 22 arranged on the drainage component 21 and used to prevent the drainage component 21 from being blocked, and a collection component 23 arranged on the drainage component 21 and used to collect and discharge the lead paste concentratedly.

[0049] In this embodiment, by setting the auxiliary mechanism 2, the problem that some lead paste is difficult to settle due to the influence of water surface fluctuations is solved, the sedimentation efficiency is accelerated, and the recovery rate of lead raw materials is improved.

[0050] Specifically, when the separation mechanism 1 works, the drainage component 21 drives the water flow at the first water washing position and the second water washing position to increase the downward movement trend through negative pressure, thereby helping more lead paste debris leave the position with large fluctuations, and then accelerating the sedimentation process.

[0051] Further, as Figure 2 and Figures 8 to 9 shown, the drainage component 21 includes a protection box 211 connected to the sorting tank 100, a U-shaped tube 212 connected to the protection box 211 and provided with a liquid inlet hole 210, a filter box 214 connected to the protection box 211 and communicated with the U-shaped tube 212 through a branch pipe 213, a filter plate 215 connected to the filter box 214, a drain pipe 216 connected to the bottom of the filter box 214, a fifth motor 217 connected to the sorting tank 100, a propeller blade 218 connected to the output end of the fifth motor 217 and located inside the U-shaped tube 212, a scraper 2110 connected to the sorting tank 100 through a torsion spring member 219 and located below the conveying component 11, and an infusion groove 2111 opened inside the scraper 2110. The drain pipe 216 is communicated with the infusion groove 2111 and a three-way pipe 158.

[0052] It is worth mentioning here that by setting the drainage component 21 in the auxiliary mechanism 2, the water flow is guided at both sides of the sorting tank 100, thereby driving some suspended lead paste to move and be collected, preventing too much lead paste from being carried when the plastic fragments are output, and at the same time accelerating the sedimentation effect is also beneficial to reducing the situation of lead paste being output with the solution, thereby reducing the pressure of the pressure filtration work.

[0053] Specifically, during the separation process, due to the falling and transmission of plastic fragments, the water surface at the first water washing position and the second water washing position fluctuates. At this time, the fifth motor 217 drives the propeller blade 218 to rotate through the output end, thereby forming a negative pressure inside the U-shaped tube 212, causing external water flow to enter the U-shaped tube 212 from the liquid inlet hole 210. The orientations of the liquid inlet holes 210 correspond to the first water washing position and the second water washing position respectively, thereby guiding the lead paste debris suspended on both sides to move downward and be collected. After reaching the filter box 214 through the branch pipe 213, the lead paste with larger particle size is blocked by the filter plate 215, while the tiny lead paste debris passes through the filter plate 215 and then is conveyed to the infusion tank 2111 inside the three-way pipe 158 and the scraper 2110 through the drain pipe 216. When the liquid discharges from the end of the infusion tank 2111, it flushes the bottom of the conveyor belt 116, causing the lead paste separated from the plastic fragments to detach from the conveyor belt 116. At the same time, the torsion spring member 219 drives the scraper 2110 to always fit with the conveyor belt 116 to scrape off the lead paste.

[0054] It should be noted that the positions of the multiple liquid inlet holes 210 are different, thereby preventing the situation where all of them are closed at the same time. The central position of the filter plate 215 is provided with a columnar groove, which is conducive to concentrating the lead paste debris.

[0055] Further, as Figure 2 and Figures 8 to 9 shown, the dredging assembly 22 includes two sets of mounting boxes 221 connected to the U-shaped tube 212, a first reciprocating lead screw 222 connected inside the mounting box 221, multiple sets of cleaning plates 223 connected to the mounting box 221 and connected to the first reciprocating lead screw 222, a first sealing plate 224 connected to the cleaning plate 223, and a first bevel gear transmission member 225 connected between the output end of the fifth motor 217 and the first reciprocating lead screw 222.

[0056] In this embodiment, by setting the dredging assembly 22, it effectively prevents the lead paste that cannot enter the liquid inlet hole 210 from blocking the liquid inlet hole 210, ensuring the normal progress of the water flow guiding work.

[0057] Specifically, when the fifth motor 217 works, it drives the first reciprocating lead screws 222 on both sides to rotate through the first bevel gear transmission member 225, thereby driving multiple sets of cleaning plates 223 to move back and forth near the liquid inlet hole 210 to complete the cleaning work and prevent blockage.

[0058] It should be noted that multiple sets of threads are provided on the first reciprocating lead screw 222 for driving multiple sets of cleaning plates 223 to reciprocate in a fixed area. Slots for the cleaning plates 223 to move are opened on the mounting box 221, and the first sealing plate 224 is used to prevent liquid from flowing into the mounting box 221 through the slots.

[0059] Embodiment 2 AsFigure 2 and Figures 8 to 11 As shown in Figures 8 to 11 , the same or corresponding components as those in the first embodiment are marked with corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The differences between the second embodiment and the first embodiment are as follows: As Figure 2 and Figures 8 to 11 shown, the collection assembly 23 includes a second reciprocating lead screw 232 connected to the protection box 211 and connected to the output end of the fifth motor 217 through a second bevel gear transmission member 231, a rotary brush 234 connected to the end of the second reciprocating lead screw 232 through a third bevel gear transmission member 233 and located at the center of the filter plate 215, a sewage discharge groove 235 formed in the filter plate 215 and the filter box 214, a blocking plate 236 connected to the filter plate 215, a plugging frame 237 penetrating through the filter box 214 and used for closing the sewage discharge groove 235, a third spring 238 connected between the plugging frame 237 and the filter box 214, and a current intercepting member 239 connected to the filter box 214; The current intercepting member 239 includes a second sealing plate 2392 connected to the filter box 214 and connected with a transmission shaft 2391, two second racks 2394 connected to the second sealing plate 2392 and connected with current intercepting plates 2393, a second gear 2395 connected to the transmission shaft 2391 and meshing with the two second racks 2394, an opening and closing rack 2396 connected to the filter box 214 and meshing with the second gear 2395, a driving rod 2397 connected to the filter box 214 and connected with the transmission shaft 2391, a fourth spring 2398 connected between the driving rod 2397 and the filter box 214, a moving block 2399 connected to the second reciprocating lead screw 232, and a triangular block 2390 connected to the moving block 2399 and used for driving the plugging frame 237 to move.

[0060] In this embodiment, by setting the collection assembly 23 in the auxiliary mechanism 2, when the drainage assembly 21 works, the lead paste debris with larger volume is actively collected and discharged after agglomeration, thereby improving the sedimentation effect. At the same time, the liquid containing only tiny lead paste debris after treatment is used for the cleaning work of the conveying assembly 11 and the centrifugal assembly 14, improving the utilization rate of water resources.

[0061] Specifically, when the fifth motor 217 works, the second reciprocating lead screw 232 is driven to rotate through the second bevel gear transmission member 231. At the same time, due to the transmission connection between the third bevel gear transmission member 233 and the end of the second reciprocating lead screw 232, the rotary brush 234 rotates and sweeps on the filter plate 215, and cooperates with the blocking plate 236 to squeeze and aggregate the lead paste debris that has not passed through the filter plate 215, concentrating at the position of the sewage discharge groove 235; When the second reciprocating screw rod 232 rotates, it also drives the moving block 2399 to move upward along one side of the filter box 214. In the initial stage of movement, it does not drive other positions to work. When it rises to a certain height, the moving block 2399 contacts and squeezes the bending part of the end of the driving rod 2397, thereby driving the driving rod 2397 to move upward. The driving rod 2397 drives the second sealing plate 2392 to move upward through the transmission shaft 2391. During the process, the second gear 2395 connected to the transmission shaft 2391 is engaged with the opening and closing rack 2396, so that the two sets of second racks 2394 drive the corresponding intercepting plates 2393 to move until the filter box 214 is reached. It is blocked by the intercepting plate 2393. At the same time, the triangular block 2390 connected to the moving block 2399 is also squeezing the blocking frame 237. When the blocking frame 237 moves, it opens one end of the sewage trough 235, and then the water flow direction begins to flow out from the sewage trough 235, and the gathered lead paste is brought out. The lead paste aggregate with a certain volume can settle quickly under the action of gravity; the moving block 2399 reaches the top at the same time when the intercepting plate 2393 closes the filter box 214, and then begins to move downward, and then the blocking frame 237 and the intercepting plate 2393 begin to reset under the drive of the third spring 238 and the fourth spring 2398.

[0062] It should be noted that the rotating brush 234 is made of flexible material and deforms to avoid the blocking plate 236 after contacting it. A groove for the transmission shaft 2391 to move is provided on the filter box 214. The function of the second sealing plate 2392 is to prevent the water in the filter box 214 from entering the protection box 211.

[0063] Working steps Step 1: First washing and separation: the product of the lead-acid battery after the crushing process enters one side of the separation tank 100 along with the water flow, and objects of different densities begin to separate in the water. The lead sinks quickly and is collected and transported by the spiral auger at the bottom, while the plastic fragments move toward the transmission assembly position; Step 2: scrubbing. The salvaging component 12 sends the plastic fragments to the transmission component in waves, and cooperates with the kneading component 13 to drive the broken pieces to vibrate and flip during transmission, thereby fully scrubbing and separating the lead paste; Step 3: Second water washing and separation, the washed plastic fragments fall into the water again, and the loose lead paste is removed by impact; Step 4: Centrifugal separation. Then, driven by the manipulator, the plastic fragments are alternately placed in two groups of conical centrifugal barrels 142 in the centrifugal assembly 14 for centrifugal separation to prevent the plastic fragments from carrying unsettled lead paste debris out; Step 5. Guided sedimentation: During the processes of the first water washing separation and the second water washing separation, the drainage assembly 21 guides the flow directions of the two water flows, thereby collecting the lead paste debris that cannot settle due to water flow disturbance, and continuously aggregating and finally discharging the sediment under the action of the collection assembly 23. The dredging assembly 22 prevents the drainage assembly 21 from being blocked during the process.

[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
