Description

Technical Field

[0001] This invention belongs to the field of battery crushing technology, specifically a waste lead-acid battery crushing equipment. Background Technology

[0002] With the large-scale application of lead-acid batteries, the amount of waste batteries generated continues to grow, and mechanical crushing equipment has gradually become the core processing equipment for the resource recycling of waste lead-acid batteries. This type of equipment relies on mechanical crushing to dismantle the battery casing and internal components, and is widely used in hazardous waste recycling companies. In conjunction with a closed operating structure, it completes the battery crushing process, providing the basic material conditions for subsequent material sorting and recycling.

[0003] A patent with publication number CN115365273A discloses a waste lead-acid battery crusher, including a processing table. The bottom of the processing table has a drive groove, and a rotating shaft is rotatably connected to the inner wall of the drive groove. A drive motor is fixed at the upper end of the processing table, and the output shaft of the drive motor is fixed to the upper end of the rotating shaft. A magnetic block is fixed to the side wall of the rotating shaft. A crushing chamber is formed in the side wall of the processing table, and a magnetic door is installed at the opening of the crushing chamber. A crushing chute corresponding to the position of the crushing chamber is formed in the inner wall of the drive groove, and a crushing drive motor is provided inside the crushing chute.

[0004] However, in the existing waste lead-acid battery crushers, after the waste lead-acid batteries are crushed, the electrolyte, battery casing, and internal active materials generated from the crushing process are all collected in the collection frame. The various materials are mixed together, making it impossible to achieve the initial separation of the casing, electrolyte, and lead paste. After crushing, a separate sorting device is still required for subsequent sorting operations, which increases the processing steps and equipment investment. At the same time, the crushing operation of waste lead-acid batteries generates a large amount of lead-containing dust and lead paste. Some of the dust will fly around inside the crushing chamber and easily escape from the equipment gaps, causing pollution to the working environment. The lead paste generated from the crushing is adhesive and easily adheres to the surface of the crushing roller. As the equipment continues to run, the lead paste gradually loses water and dries to form hard lumps, changing the original tooth structure of the crushing roller, thereby reducing the shearing and crushing effect of the crushing roller. Long-term accumulation will also aggravate the wear of the crushing roller and affect the stable and continuous operation of the equipment.

[0005] Therefore, the present invention provides a waste lead-acid battery crushing device. Summary of the Invention

[0009] Preferably, the switching component includes a first guide rail fixed to both sides of the feeding frame, the surface of the first guide rail is provided with a first guide groove, the two first guide rails are slidably connected to the same fixing plate, and the lower surface of the fixing plate is provided with spray holes to spray clean water to settle during the crushing operation of the crushing roller.

[0010] Preferably, a fixed box and an auxiliary box are fixedly connected to the upper surface of the fixed plate. The fixed box contains soda water, and the auxiliary box contains clean water.

[0011] Preferably, a sliding groove is provided between the fixed box and the auxiliary box. A telescopic rod is fixedly connected to the top wall of the sliding groove. A spring is sleeved on the circumference of the telescopic rod. The spring and the bottom end of the telescopic rod are fixedly connected to the same conical plate. An auxiliary hole is provided inside the conical plate. A fixing hole is provided on one side of the sliding groove. A limiting hole and a connecting hole are also provided on the inner wall of the sliding groove. The limiting hole and the connecting hole are located on corresponding sides.

[0012] Preferably, a limiting groove is also provided inside the sliding groove, and a sliding plate is slidably connected inside the limiting groove. The sliding plate is used to block the limiting hole. The sliding plate is a magnetic suction plate, and the cone plate is an electro-permanent magnet plate.

[0013] Preferably, the upper surface of the feeding frame is provided with a rotating groove, and a rotating roller is rotatably connected in the rotating groove. The rotating roller is a brush roller. A fixed cylinder is fixedly connected to one side of the feeding frame. A fixed cavity is provided in the fixed cylinder. A take-up roller is rotatably connected in the fixed cavity. A shielding strip is wound on the surface of the take-up roller. The shielding strip is polyester needle-punched felt.

[0014] Preferably, the bottom of the fixing frame is provided with a limiting component, the limiting component includes auxiliary plates fixed to both sides of the fixing frame, the auxiliary plates have auxiliary grooves inside, the inner wall of the auxiliary grooves is fixed with a plurality of auxiliary springs, the plurality of auxiliary springs are fixed with the same push block, and the two auxiliary plates are fixed with the same stop block on one side.

[0015] Preferably, during the crushing of waste lead-acid batteries, the first guide rails on both sides of the feeding frame are activated first, causing the fixing plate inside the first guide rail to slide away from the crushing roller. However, the cone plate on the lower surface of the fixing plate does not abut against the feeding frame, thus opening the feeding frame and allowing the waste lead-acid batteries to be fed in. The waste lead-acid batteries are placed into the feeding frame and guided by the feeding frame to fall between the two crushing rollers. Then, the first guide rails are activated to drive the fixing plate to reset and cover the feeding opening of the feeding frame. The fixed motor is then activated to drive the crushing rollers to perform the crushing operation. Simultaneously, the auxiliary box on the upper surface of the fixing plate is activated to assist in the crushing process. After the pressure pump inside the tank is started, it pressurizes the clean water stored inside. The pressurized clean water flows through the connecting hole into the fixing hole, and then sprays out from the holes on the lower surface of the fixing plate to settle the dust generated during the crushing process. The crushed waste lead-acid batteries move downward and fall into the rotating drum through the guide frame. The auger inside the rotating drum guides the crushed waste lead-acid battery casings, while the crushed powdered lead paste is scraped and collected into the collection box below the feeding frame through the feeding hole on the surface of the rotating drum. The waste lead-acid battery casings are then conveyed to the outside by the auger for collection.

[0016] Preferably, after the waste lead-acid batteries are crushed, the shielding strip inside the fixing cylinder is pulled out and adhered to one side of the fixing plate. Then, the first guide rail is activated again to drive the fixing plate. The sliding of the fixing plate pulls the shielding strip to close the top of the feeding frame, preventing residual dust in the feeding frame from escaping after crushing. The continuous movement of the fixing plate causes the cone plate on the lower surface of the fixing plate to abut against the upper surface of the feeding frame. The cone plate is squeezed into the sliding groove. At the same time, the pressure sensor at the bottom of the cone plate receives a signal, making the cone plate magnetic. Then, as the cone plate slides upward, until it is completely squeezed, the cone plate will be magnetically attracted. Inside the sliding groove, the cone plate does not block the fixing hole. The inner wall of the sliding groove near the connecting hole is made of magnetic material. At this time, one side of the cone plate blocks the fixing hole, while the other side of the cone plate aligns with the limiting hole opened inside the fixing box. An auxiliary hole is opened on this side of the cone plate. The cross-section of the auxiliary hole is "L". After aligning with the limiting hole, the pressure pump inside the fixing box starts, pressurizes the soda water inside, and then flows into the fixing hole from the limiting hole. Then it is sprayed out from the lower surface of the fixing plate to soften the lead paste and lead sulfate mud layer adhering to the inner wall of the feeding frame and the surface of the crushing roller, and then washes it off and collects it by the collection box.

[0017] The beneficial effects of this invention are as follows: 1. The waste lead-acid battery crushing equipment of the present invention opens and closes the feeding frame by driving the fixed plate through the first guide rail, which can complete the feeding operation of waste lead-acid batteries. After the feeding is completed, the fixed plate closes the feeding port, which can reduce the dust emission during the crushing process. During the crushing operation, the pressure pump in the auxiliary box pressurizes the clean water and sprays it out from the holes on the lower side of the fixed plate. This can directly spray and settle the dust generated at the crushing station, suppress the diffusion of lead dust, improve the working environment, and reduce the safety hazards caused by lead dust pollution. The crushed material is sent into the rotating drum through the guide frame, and the material is conveyed and separated by the auger. The auger scrapes the lead paste powder through the discharge hole into the collection box, and the battery shell is conveyed and discharged separately, realizing the automatic screening and separation of lead paste and shell without manual sorting, improving the processing efficiency, reducing the direct contact between personnel and hazardous materials, and improving the automation level and operational safety of waste lead-acid battery crushing and processing.

[0018] 2. The waste lead-acid battery crushing equipment of the present invention, by pulling out the shielding strip and sticking it to the side of the fixed plate, and cooperating with the first guide rail to drive the fixed plate to slide, can temporarily close the upper part of the feeding frame, preventing the residual dust in the frame from escaping after crushing, reducing the risk of lead dust leakage and pollution. At the same time, the pressure sensor triggered by the compression of the cone plate realizes magnetic positioning, ensuring that the cone plate is stably stored in the sliding groove and does not block the fixed hole. When the auxiliary hole of the cone plate is aligned with the limit hole, the pressure pump pressurizes and delivers soda water, which is sprayed out from the lower surface of the fixed plate through the limit hole and the fixed hole. The soda water softens and washes the lead paste and lead sulfate mud layer attached to the inner wall of the feeding frame and the surface of the crushing roller, cleaning and washing off the adhering dirt and putting it into the collection box. There is no need for manual disassembly and cleaning, reducing the operator's contact with corrosive and lead-containing dirt, realizing automatic cleaning and descaling of the equipment, improving the cleanliness of the equipment, reducing corrosion and secondary pollution caused by material residue, and ensuring the stable operation of subsequent crushing operations.

A fixed plate 19 is slidably connected to the upper part of the crushing roller 113. The lower surface of the fixed plate 19 has spray holes for spraying clean water to reduce sedimentation during the crushing operation. A fixed box 4 and an auxiliary box 41 are fixedly connected to the upper surface of the fixed plate 19. The fixed box 4 stores soda water, and the auxiliary box 41 stores clean water. A sliding groove 46 is provided between the fixed box 4 and the auxiliary box 41. A telescopic rod 49 is fixedly connected to the top wall of the sliding groove 46. A spring 410 is fitted on the circumference of the telescopic rod 49. The spring 410 and the bottom end of the telescopic rod 49 are fixedly connected to the same conical plate 411. An auxiliary hole 412 is provided inside the conical plate 411. A fixed hole 47 is provided on one side of the sliding groove 46. A limit switch is also provided on the inner wall of the sliding groove 46. Hole 414 and connecting hole 48, and limiting hole 414 and connecting hole 48 are located on corresponding sides; a limiting groove 415 is also opened inside the sliding groove 46, and a sliding plate 413 is slidably connected inside the limiting groove 415. The sliding plate 413 is used to block the limiting hole 414. The sliding plate 413 is a magnetic suction plate, and the cone plate 411 is an electro-permanent magnet plate; a rotating groove 110 is opened on the upper surface of the feeding frame 14, and a rotating roller 111 is rotatably connected inside the rotating groove 110. The rotating roller 111 is a brush roller. A fixed cylinder 42 is fixedly connected to one side of the feeding frame 14. A fixed cavity 43 is opened inside the fixed cylinder 42. A winding roller 44 is rotatably connected inside the fixed cavity 43. A shielding strip 45 is wound on the surface of the winding roller 44. The shielding strip 45 is polyester needle-punched felt; Specifically, in the existing waste lead-acid battery crusher, after the waste lead-acid battery is crushed, the electrolyte, battery casing, and internal active materials generated by the crushing are all collected in the collection frame. The various materials are mixed together, making it impossible to achieve the initial separation of casing, electrolyte, and lead paste. After crushing, a separate sorting device is still required for subsequent sorting operations, which increases the processing steps and equipment investment. At the same time, the waste lead-acid battery crushing operation generates a large amount of lead-containing dust and lead paste. Some of the dust will fly around inside the crushing chamber and easily escape from the equipment gaps, causing pollution to the working environment. The lead paste generated by the crushing is adhesive and easily adheres to the surface of the crushing roller 113. As the equipment continues to run, the lead paste gradually loses water and dries to form hard lumps, changing the original tooth structure of the crushing roller 113, thereby reducing the shearing and crushing effect of the crushing roller 113. Long-term accumulation will also aggravate the wear of the crushing roller 113, affecting the stable and continuous operation of the equipment. Therefore, the present invention solves the above problems by setting the above structure. First, when crushing waste lead-acid batteries, the first guide rails 17 on both sides of the feeding frame 14 are activated, causing the fixing plate 19 inside the first guide rail 17 to slide away from the crushing roller 113. However, the cone plate 411 on the lower surface of the fixing plate 19 does not abut against the feeding frame 14, thereby opening the feeding frame 14 and feeding the waste lead-acid batteries. The waste lead-acid batteries are placed into the feeding frame 14 and guided by the feeding frame 14 to fall between the two crushing rollers 113. Then, by activating the first guide rails 17, the fixing plate 19 is driven to reset and cover the feeding port of the feeding frame 14. The fixed motor 13 is started to drive the crushing roller 113 to carry out the crushing work. At the same time, the crushing is carried out. The auxiliary box 41 on the upper surface of the fixed plate 19 is activated. After the pressure pump in the auxiliary box 41 is activated, it pressurizes the clean water stored inside. The pressurized clean water is introduced into the fixed hole 47 through the connecting hole 48, and then sprayed out from the hole on the lower surface of the fixed plate 19 to settle the dust generated by the crushing operation. The crushed waste lead-acid battery moves downward and falls into the rotating drum 3 under the guidance of the guide frame 35. The auger 34 in the rotating drum 3 guides the crushed waste lead-acid battery shell. At the same time, the crushed powder lead paste is scraped and collected into the collection box 16 below the feeding frame 15 through the feeding hole 32 on the surface of the rotating drum 3. The waste lead-acid battery shell is conveyed to the outside by the auger 34 for collection. The loading frame 14 is opened and closed by driving the fixed plate 19 through the first guide rail 17, which can complete the loading operation of waste lead-acid batteries. After loading is completed, the fixed plate 19 closes the loading port, which can reduce the dust from escaping during the crushing process. During the crushing operation, the pressure pump in the auxiliary box 41 pressurizes the clean water and sprays it out through the holes on the lower side of the fixed plate 19. This can directly spray and settle the dust generated at the crushing station, suppress the diffusion of lead dust, improve the working environment, and reduce the safety hazards caused by lead dust pollution. The crushed material is sent into the rotating drum 3 through the guide frame 35. The auger 34 is used to realize the material conveying and separation. The auger 34 scrapes the lead paste powder through the discharge hole 32 and falls into the collection box 16. The battery shell is conveyed and discharged separately, realizing the automatic screening and separation of lead paste and shell. There is no need for manual sorting, which improves the processing efficiency and reduces the direct contact between personnel and hazardous materials, thereby improving the automation level and operational safety of waste lead-acid battery crushing and processing. After the waste lead-acid batteries are crushed, the shielding strip 45 inside the fixing cylinder 42 is pulled out and adhered to one side of the fixing plate 19. Then, the first guide rail 17 is started again to drive the fixing plate 19. The sliding of the fixing plate 19 pulls the shielding strip 45 to close the top of the feeding frame 14, preventing the dust remaining in the feeding frame 14 after crushing from escaping. The continuous movement of the fixing plate 19 causes the cone plate 411 on the lower surface of the fixing plate 19 to abut against the upper surface of the feeding frame 14. The cone plate 411 is squeezed into the sliding groove 46, and at the same time, the bottom end of the cone plate 411... When the pressure sensor receives a signal, the cone plate 411 becomes magnetic. As the cone plate 411 slides upward until it is fully compressed, it will be magnetically attracted to the sliding groove 46. However, the cone plate 411 will not block the fixing hole 47. The inner wall of the sliding groove 46 is made of magnetic material near the connecting hole 48. At this time, one side of the cone plate 411 blocks the fixing hole 47, while the other side of the cone plate 411 aligns with the limiting hole 414 inside the fixing box 4. An auxiliary hole 412 is provided on this side of the cone plate 411. The cross-section of the auxiliary hole 412 is "L". After the cone plate 19 is aligned with the limiting hole 414, the internal pressure pump of the fixed box 4 is activated, pressurizing the soda water inside, which flows from the limiting hole 414 into the fixed hole 47, and then sprays out from the lower surface of the fixed plate 19. This softens the lead paste and lead sulfate mud layer adhering to the inner wall of the feeding frame 14 and the surface of the crushing roller 113, and then washes it off. The mud is then collected by the collection box 16. After the washing operation is completed, the first guide rail 17 is activated again, driving the fixed plate 19 and simultaneously pulling the winding shielding belt 45. At this time, the pressure sensor receives a signal again, causing the cone plate to activate. 411 loses its magnetism, and the shielding strip 45 is cut off. The lead dust attached to it can be re-bonded during the next flushing operation. After cutting, the waste lead-acid battery is fed again for the next batch of crushing. In addition, after the cone plate 411 loses its magnetism, after the fixed plate 19 is reset and the feeding frame 14 is sealed after the feeding is completed, the cone plate 411 is reset under the reset force of the spring 410, and the sliding plate 413 will move down under the action of gravity to cover the limiting hole 414 again. Then the connecting hole 48 and the fixed hole 47 are connected again to carry out the crushing and dust reduction work. By pulling out the shielding strip 45 and attaching it to the side of the fixing plate 19, and cooperating with the first guide rail 17 to drive the fixing plate 19 to slide, the upper part of the feeding frame 14 can be temporarily closed, preventing the residual dust inside the frame from escaping after crushing, thus reducing the risk of lead dust leakage and pollution. At the same time, the pressure sensor is triggered by the compression of the cone plate 411 to achieve magnetic positioning, ensuring that the cone plate 411 is stably stored in the sliding groove 46 without blocking the fixing hole 47. When the auxiliary hole 412 of the cone plate 411 is aligned with the limiting hole 414, the pressure pump adds soda water. The pressure conveyor sprays water from the lower surface of the fixed plate 19 through the limiting hole 414 and the fixing hole 47. The water softens and washes away the lead paste and lead sulfate mud layer adhering to the inner wall of the feeding frame 14 and the surface of the crushing roller 113 with the help of soda water. The adhering dirt is washed off and put into the collection box 16. There is no need for manual disassembly and cleaning, which reduces the operator's contact with corrosive and lead-containing dirt. It realizes automatic cleaning and descaling of the equipment, improves the cleanliness of the equipment, reduces corrosion and secondary pollution caused by material residue, and ensures stable operation of subsequent crushing operations.

[0023] Example 2: Figures 1 to 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the bottom of the fixed frame 1 is provided with a limiting component, the limiting component includes auxiliary plates 2 fixed to both sides of the fixed frame 1, the auxiliary plates 2 have an auxiliary groove 21 inside, the inner wall of the auxiliary groove 21 is fixed with a plurality of auxiliary springs 22, the plurality of auxiliary springs 22 are fixed with the same push block 23, and the same stop block 24 is fixed to one side of the two auxiliary plates 2.

[0024] Specifically, when installing the collection box 16, the collection box 16 is pushed between the two auxiliary plates 2. During the pushing process, the push block 23 inside the two auxiliary plates 2 is squeezed, thereby squeezing the internal auxiliary spring 22, until the collection box 16 abuts against the stop block 24, thereby completing the snap-fit ​​of the collection box 16. At the same time, the collection box 16 is directly below the unloading frame 15.

[0025] Working principle: First, when crushing waste lead-acid batteries, the first guide rails 17 on both sides of the feeding frame 14 are activated, causing the fixing plate 19 inside the first guide rail 17 to slide away from the crushing roller 113. However, the cone plate 411 on the lower surface of the fixing plate 19 does not abut against the feeding frame 14, thus opening the feeding frame 14 and allowing the waste lead-acid batteries to be fed in. The waste lead-acid batteries are placed into the feeding frame 14 and guided by the feeding frame 14 to fall between the two crushing rollers 113. Then, by activating the first guide rails 17, the fixing plate 19 is reset to cover the feeding port of the feeding frame 14. The fixed motor 13 is activated to drive the crushing roller 113 to perform the crushing operation. At the same time as crushing, the fixing plate 19 is activated. The auxiliary box 41 on the surface pressurizes the clean water stored inside after the pressure pump inside the auxiliary box 41 is started. The pressurized clean water is introduced into the fixing hole 47 through the connecting hole 48, and then sprayed out from the hole on the lower surface of the fixing plate 19 to settle the dust generated by the crushing operation. The crushed waste lead-acid battery moves downward and falls into the rotating drum 3 under the guidance of the guide frame 35. The auger 34 in the rotating drum 3 guides the crushed waste lead-acid battery shell. At the same time, the crushed powder lead paste is scraped and collected into the collection box 16 below the feeding frame 15 through the feeding hole 32 on the surface of the rotating drum 3. The waste lead-acid battery shell is conveyed to the outside by the auger 34 for collection. The loading frame 14 is opened and closed by driving the fixed plate 19 through the first guide rail 17, which can complete the loading operation of waste lead-acid batteries. After loading is completed, the fixed plate 19 closes the loading port, which can reduce the dust from escaping during the crushing process. During the crushing operation, the pressure pump in the auxiliary box 41 pressurizes the clean water and sprays it out through the holes on the lower side of the fixed plate 19. This can directly spray and settle the dust generated at the crushing station, suppress the diffusion of lead dust, improve the working environment, and reduce the safety hazards caused by lead dust pollution. The crushed material is sent into the rotating drum 3 through the guide frame 35. The auger 34 is used to realize the material conveying and separation. The auger 34 scrapes the lead paste powder through the discharge hole 32 and falls into the collection box 16. The battery shell is conveyed and discharged separately, realizing the automatic screening and separation of lead paste and shell. There is no need for manual sorting, which improves the processing efficiency and reduces the direct contact between personnel and hazardous materials, thereby improving the automation level and operational safety of waste lead-acid battery crushing and processing. After the waste lead-acid batteries are crushed, the shielding strip 45 inside the fixing cylinder 42 is pulled out and adhered to one side of the fixing plate 19. Then, the first guide rail 17 is started again to drive the fixing plate 19. The sliding of the fixing plate 19 pulls the shielding strip 45 to close the top of the feeding frame 14, preventing the dust remaining in the feeding frame 14 after crushing from escaping. The continuous movement of the fixing plate 19 causes the cone plate 411 on the lower surface of the fixing plate 19 to abut against the upper surface of the feeding frame 14. The cone plate 411 is squeezed into the sliding groove 46, and at the same time, the bottom end of the cone plate 411... When the pressure sensor receives a signal, the cone plate 411 becomes magnetic. As the cone plate 411 slides upward until it is fully compressed, it will be magnetically attracted to the sliding groove 46. However, the cone plate 411 will not block the fixing hole 47. The inner wall of the sliding groove 46 is made of magnetic material near the connecting hole 48. At this time, one side of the cone plate 411 blocks the fixing hole 47, while the other side of the cone plate 411 aligns with the limiting hole 414 inside the fixing box 4. An auxiliary hole 412 is provided on this side of the cone plate 411. The cross-section of the auxiliary hole 412 is "L". After the cone plate 19 is aligned with the limiting hole 414, the internal pressure pump of the fixed box 4 is activated, pressurizing the soda water inside, which flows from the limiting hole 414 into the fixed hole 47, and then sprays out from the lower surface of the fixed plate 19. This softens the lead paste and lead sulfate mud layer adhering to the inner wall of the feeding frame 14 and the surface of the crushing roller 113, and then washes it off. The mud is then collected by the collection box 16. After the washing operation is completed, the first guide rail 17 is activated again, driving the fixed plate 19 and simultaneously pulling the winding shielding belt 45. At this time, the pressure sensor receives a signal again, causing the cone plate to activate. 411 loses its magnetism, and the shielding strip 45 is cut off. The lead dust attached to it can be re-bonded during the next flushing operation. After cutting, the waste lead-acid battery is fed again for the next batch of crushing. In addition, after the cone plate 411 loses its magnetism, after the fixed plate 19 is reset and the feeding frame 14 is sealed after the feeding is completed, the cone plate 411 is reset under the reset force of the spring 410, and the sliding plate 413 will move down under the action of gravity to cover the limiting hole 414 again. Then the connecting hole 48 and the fixed hole 47 are connected again to carry out the crushing and dust reduction work. By pulling out the shielding strip 45 and attaching it to the side of the fixing plate 19, and cooperating with the first guide rail 17 to drive the fixing plate 19 to slide, the upper part of the feeding frame 14 can be temporarily closed, preventing the residual dust inside the frame from escaping after crushing, thus reducing the risk of lead dust leakage and pollution. At the same time, the pressure sensor is triggered by the compression of the cone plate 411 to achieve magnetic positioning, ensuring that the cone plate 411 is stably stored in the sliding groove 46 without blocking the fixing hole 47. When the auxiliary hole 412 of the cone plate 411 is aligned with the limiting hole 414, the pressure pump adds soda water. The pressure conveyor sprays water from the lower surface of the fixed plate 19 through the limiting hole 414 and the fixing hole 47. The water softens and washes away the lead paste and lead sulfate mud layer adhering to the inner wall of the feeding frame 14 and the surface of the crushing roller 113 with the help of soda water. The adhering dirt is washed off and put into the collection box 16. There is no need for manual disassembly and cleaning, which reduces the operator's contact with corrosive and lead-containing dirt. It realizes automatic cleaning and descaling of the equipment, improves the cleanliness of the equipment, reduces corrosion and secondary pollution caused by material residue, and ensures stable operation of subsequent crushing operations.

The same stop block (24) is fixed to one side of the two auxiliary plates (2).

9. The waste lead-acid battery crushing equipment according to claim 7, characterized in that: When crushing waste lead-acid batteries, the first guide rails (17) on both sides of the feeding frame (14) are activated first, so that the fixed plate (19) inside the first guide rail (17) slides away from the crushing roller (113). However, the cone plate (411) on the lower surface of the fixed plate (19) does not abut against the feeding frame (14), thus opening the feeding frame (14) and feeding the waste lead-acid batteries. The waste lead-acid batteries are placed into the feeding frame (14) and guided by the feeding frame (14) to fall between the two crushing rollers (113). Then, by activating the first guide rail (17), the fixed plate (19) is driven to reset the feeding port of the shielding column feeding frame (14). The fixed motor (13) is activated to drive the crushing roller (113) to carry out the crushing work. At the same time as crushing, the fixed plate (19) is activated. The auxiliary box (41) on the surface pressurizes the clean water stored inside after the pressure pump inside the auxiliary box (41) is started. The pressurized clean water is passed through the connecting hole (48) into the fixed hole (47) and then sprayed out from the hole on the lower surface of the fixed plate (19) to settle the dust generated by the crushing operation. The crushed waste lead-acid battery moves downward and falls into the rotating drum (3) through the guide frame (35). The auger (34) in the rotating drum (3) guides the crushed waste lead-acid battery shell. At the same time, the crushed powder lead paste is scraped and collected into the collection box (16) below the feeding frame (15) through the feeding hole (32) on the surface of the rotating drum (3). The waste lead-acid battery shell is conveyed to the outside by the auger (34) for collection.

10. The waste lead-acid battery crushing equipment according to claim 7, characterized in that: After the waste lead-acid battery is crushed, the shielding strip (45) inside the fixed cylinder (42) is pulled out and glued to one side of the fixed plate (19). Then, the first guide rail (17) is started again to drive the fixed plate (19). The sliding of the fixed plate (19) pulls the shielding strip (45) to close the top of the feeding frame (14) to prevent the dust remaining in the feeding frame (14) after crushing from escaping. The continuous movement of the fixed plate (19) causes the cone plate (411) on the lower surface of the fixed plate (19) to abut against the upper surface of the feeding frame (14). The cone plate (411) is squeezed into the sliding groove (46). At the same time, the pressure sensor at the bottom of the cone plate (411) receives a signal, making the cone plate (411) magnetic. Then, as the cone plate (411) slides upward, until it is completely squeezed, the cone plate (411) will be magnetically attracted to the sliding groove (46). 6) Inside, but the cone plate (411) will not block the fixing hole (47). The inner wall of the sliding groove (46) near the connecting hole (48) is made of magnetic material. At this time, one side of the cone plate (411) blocks the fixing hole (47), and the other side of the cone plate (411) will be aligned with the limiting hole (414) opened inside the fixing box (4). The cone plate (411) has an auxiliary hole (412) on this side. The cross section of the auxiliary hole (412) is "L". After it is aligned with the limiting hole (414), the pressure pump inside the fixing box (4) starts, pressurizes the soda water inside, and flows into the fixing hole (47) from the limiting hole (414). Then it is sprayed out from the lower surface of the fixing plate (19) to soften the lead paste and lead sulfate mud layer adhering to the inner wall of the feeding frame (14) and the surface of the crushing roller (113), and then washes it off and is collected by the collection box (16).
