Description

Technical Field

[0001] This invention relates to the field of recycling technology, specifically to a recycling process and equipment for waste lithium batteries. Background Technology

[0002] Used lithium batteries contain hazardous chemicals such as lithium, nickel, and cobalt. If not handled properly, they may leak into the environment and pollute the soil and groundwater. Therefore, it is essential to recycle used lithium batteries.

[0003] Patent CN218903041U discloses a device for dismantling and recycling waste lithium batteries, including a crushing mechanism, a solid-liquid separation mechanism, and a conveying mechanism. The solid-liquid separation mechanism includes a separation tank, a filter plate fixed inside the separation tank, and a pressing component and a pushing component disposed within the separation tank. The crushing mechanism and the conveying mechanism are respectively connected to the inlet and outlet of the separation tank. The pressing component is located directly above the filter plate, and the pushing component is located above the filter plate and extends horizontally towards the outlet. This patent achieves efficient separation of electrolyte and heavy metals, and enables rapid external discharge and recycling of the separated electrolyte and heavy metals.

[0004] The aforementioned patent achieves efficient separation of electrolyte and heavy metals, and enables rapid external discharge and recycling of the separated electrolyte and heavy metals. However, during the crushing of lithium batteries, the lithium batteries may get stuck in the crushing mechanism and cannot enter the crushing mechanism for crushing directly. At the same time, a large number of lithium batteries may enter at once, which may increase the load on the crushing mechanism, causing the crushing mechanism to get stuck and reduce its service life. Summary of the Invention

[0005] This invention proposes a recycling process and equipment for waste lithium batteries, solving a problem related to the recycling process and equipment for waste lithium batteries in related technologies.

[0006] The technical solution of the present invention is as follows:

[0007] A recycling process for used lithium batteries includes the following steps:

[0008] Step 1: The lithium battery is driven into the crushing chamber by the conveying device, and the crusher rotates to crush the lithium battery;

[0009] Step 2: As the crusher rotates, it drives the short rod to rotate as well. The short rod rotates and contacts the inclined surface of the trapezoidal block. The short rod pushes the trapezoidal block to move closer to the conveying device, thus storing force in the elastic telescopic block.

[0010] Step 3: The trapezoidal block moves towards the conveying device, which in turn moves the push plate towards the conveying device. The push plate moves towards the conveying device and squeezes the elastic telescopic block. When the short rod disengages from the trapezoidal block, the elasticity of the elastic telescopic block pushes the push plate towards the middle of the crusher, pushing the lithium battery against the edge into the middle of the crusher for crushing.

[0011] Step 4: Simultaneously, the push plate moves towards the conveying device, causing the connecting rod to move towards the conveying device. The movement of the connecting rod towards the conveying device pushes the baffle plate to rotate, allowing the lithium battery to indirectly enter the crusher for crushing.

[0012] A recycling device for waste lithium batteries includes a conveying device, a crushing device, and an anti-jamming gate device. A crushing box is fixedly installed on the surface of the conveying device, a feeding box is fixedly installed at the bottom of the crushing box, a separating box is fixedly installed on the surface of the feeding box, and a crusher is fixedly installed on the top of the separating box. The crushing device includes a crusher, a short rod, an elastic telescopic block, a pusher plate, a trapezoidal block, a connecting rod, and a baffle plate. The conveying device carries the lithium batteries into the crushing box. The crusher rotates to crush the lithium batteries. Simultaneously, the rotation of the crusher drives the short rod to rotate. The rotating short rod contacts the inclined surface of the trapezoidal block, pushing the trapezoidal block towards the conveying device. This movement of the trapezoidal block towards the conveying device causes the pusher plate to move towards the conveying device, preventing jamming. Lithium batteries stuck on both sides of the crusher cannot be crushed immediately, reducing the crusher's working efficiency. The crusher is fixedly installed on the surface of the crushing box, the short rod is fixedly installed on the output end of the crusher, the elastic telescopic block is fixedly installed on the inner wall of the crushing box, the push plate is fixedly installed on the free end of the elastic telescopic block, the trapezoidal block is fixedly installed on the bottom of the push plate, the connecting rod is fixedly installed on the top of the push plate, and the baffle plate is rotatably installed on the inner wall of the conveying device. When the push plate moves closer to the conveying device, it will drive the connecting rod to move closer to the conveying device. When the connecting rod moves closer to the conveying device, it will push the baffle plate to rotate, preventing too many lithium batteries from entering at once, which may increase the load on the crusher, potentially causing machine malfunctions and reducing the machine's service life.

[0013] According to the above technical solution, the push plate does not contact the crusher, the surface of the trapezoidal block is provided with an inclined surface, and a spring is provided between the baffle plate and the conveying device. The push plate does not contact the crusher to prevent the crusher from damaging the push plate and causing machine damage. The spring drives the baffle plate to reset, preventing the lithium batteries from being stuck and unable to enter the crusher for crushing.

[0014] According to the above technical solution, the anti-jamming door device includes an inclined plate, an elastic telescopic plate, a fixed block, a fixed plate, a rotating wheel, a connecting rope, and a rotating plate. When the fixed block moves downwards, it contacts the fixed plate, which pushes the fixed plate downwards. This downward movement of the fixed plate causes the free end of the elastic telescopic plate to move downwards, preventing compression while continuously feeding. Lithium battery debris may fall above the extruder, requiring manual cleaning. This debris may also jam the extruder, potentially causing malfunctions and affecting work efficiency. The feeding box has a discharge port on its surface, and the inclined plate is fixedly installed on the inner wall of the feeding box. The elastic telescopic plate is fixedly installed on the top of the discharge port. The fixed block is installed at the output end of the extruder, the fixed plate is fixedly installed at the free end of the elastic telescopic plate, the rotating wheel is rotatably installed on the inner wall of the feeding box, the rotating plate is rotatably installed on the surface of the inclined plate, one end of the connecting rope is fixedly installed at the free end of the elastic telescopic plate, and the other end of the connecting rope is fixedly installed on the surface of the rotating plate. At the same time, when the free end of the elastic telescopic plate moves downward, it will drive one end of the connecting rope to move downward, and when one end of the connecting rope moves downward, it will drive the other end of the connecting rope to move upward. When the other end of the connecting rope moves upward, it will drive the rotating plate to rotate upward, preventing lithium battery debris from getting stuck at the outlet and blocking the discharge port, which would prevent the discharge port from closing properly and affect the subsequent extrusion effect.

[0015] According to the above technical solution, the connecting rope is looped around the surface of the rotating wheel, a first torsion spring is provided between the rotating wheel and the feeding box, and a second torsion spring is provided between the rotating plate and the inclined plate. The rotating wheel is reset by the first torsion spring, and the rotating plate is reset by the second torsion spring. The rotating plate continuously blocks the lithium battery from entering the separation box.

[0016] According to the above technical solution, a pushing device and a separating device are provided. The pushing device includes a half gear, a rack, an L-shaped push rod, a triangular bar, an oil tank, a slider, and an L-shaped rod. The upward rotation of the rotating plate drives the half gear to rotate upward. This upward rotation of the half gear causes the rack to move closer to the separating box. The rack's movement towards the separating box causes the L-shaped push rod to move closer to the separating box. The L-shaped push rod, moving closer to the separating box, contacts the surface of the triangular bar, pushing the lithium battery debris stuck at the outlet into the separating box. This prevents the lithium battery debris from affecting the closure of the outlet, which could damage the elastic telescopic plate and affect normal closure. A groove is provided at the bottom of the inclined plate, and the half gear... The rack is fixedly installed at the bottom of the rotating plate, and the half gear is slidably installed on the inner wall of the groove. The half gear meshes with the surface of the rack. The L-shaped push rod is fixedly installed at the bottom of the rack. The triangular strip is slidably installed on the surface of the discharge port. The oil replenishment box is fixedly installed on the inner wall of the groove, and the surface of the oil replenishment box is provided with an oil outlet. The slider is slidably installed on the surface of the oil outlet. The L-shaped rod is fixedly installed on the top of the rack. When the rack moves towards the separation box, it will drive the L-shaped rod to move towards the separation box. When the L-shaped rod moves towards the separation box, it will contact the inclined surface of the slider. The L-shaped rod will push the slider to slide upward. This prevents the parts from aging due to prolonged disuse, which would reduce working efficiency and affect the normal use of the machine.

[0017] According to the above technical solution, a first spring is provided between the rack and the groove, a second spring is provided between the oil outlet and the slider, the L-shaped push rod is in contact with the surface of the triangular strip, and a reset spring is provided between the triangular strip and the outlet. The rack is reset by the first spring, and the slider is reset by the second spring to prevent the oil outlet from being continuously open and causing waste. The triangular strip is reset by the reset spring to prevent lithium battery fragments from getting stuck on the surface of the outlet.

[0018] According to the above technical solution, the separation device includes an elastic telescopic rod, a filter plate, an L-shaped rod, an inclined block, a triangular block, a triangular slider, a round rod, and a square plate. When the L-shaped rod moves downwards, it contacts the inclined surface of the inclined block, pushing the inclined block towards the inner wall of the separation chamber. This movement of the inclined block towards the inner wall of the separation chamber causes the free end of the elastic telescopic rod to move towards the inner wall of the separation chamber to store force. During the resetting process, the lithium battery debris on the surface of the filter plate is flattened to prevent excessive accumulation of lithium battery debris, which could lead to some electrolyte remaining in the lithium battery during extrusion, potentially causing harm. The elastic telescopic rod is fixedly installed on the inner wall of the separation chamber, and the filter plate is fixedly installed on... The free end of the elastic telescopic rod is fixedly installed at the output end of the extruder. The inclined block is installed at the free end of the elastic telescopic rod, the triangular block is fixedly installed on the surface of the L-shaped long rod, the triangular slider is slidably installed on the surface of the filter plate, the round rod is fixedly installed on the surface of the triangular slider, and the square plate is fixedly installed on the surface of the filter plate. At the same time, when the L-shaped long rod moves downward, it will drive the triangular block to move downward. When the triangular block moves downward, it will contact the inclined surface of the triangular slider. The triangular block will push the triangular slider to move away from the L-shaped long rod. During the process of the round rod moving away from the L-shaped long rod, it will contact the protrusion and generate vibration, which will better shake the electrolyte down and prevent the electrolyte from adhering to the filter pores, thus improving the separation effect.

[0019] According to the above technical solution, the L-shaped long rod and the inclined block are in contact, a No. 3 spring is provided between the triangular slider and the filter plate, and a protrusion is fixedly installed on the surface of the square plate. The No. 3 spring drives the triangular slider to reset, which can make the filter plate vibrate multiple times and improve the separation effect.

[0020] The working principle and beneficial effects of this invention are as follows:

[0021] 1. In this invention, the lithium battery is crushed by the rotation of the crusher. At the same time, the rotation of the crusher will drive the short rod to push the trapezoidal block, so that the elastic telescopic block will store force and push the lithium battery at the edge of the crusher towards the center of the crusher. This prevents the lithium battery from getting stuck at the edge of the crusher and being unable to be crushed quickly, which would reduce the crushing efficiency. At the same time, pushing the trapezoidal block will drive the connecting rod to push the baffle plate to block the material, preventing too many lithium batteries from entering at once. This would increase the load on the crusher, which may cause the machine to malfunction and reduce the service life of the machine.

[0022] 2. In this invention, the downward movement of the extruder causes the free end of the elastic telescopic plate to close, preventing lithium battery debris from falling onto the extruder during continuous feeding and requiring manual cleaning. This could also cause the lithium battery debris to jam the extruder, potentially leading to malfunctions and reduced work efficiency. Simultaneously, the downward movement of the free end of the elastic telescopic plate pulls the rotating plate upward, preventing lithium battery debris from getting stuck at the outlet and blocking the discharge port, thus preventing the outlet from closing properly and affecting subsequent extrusion results.

[0023] 3. In this invention, the upward rotation of the rotating plate drives the half gear to rotate, thereby pushing the triangular strip to slide and pushing the lithium battery debris stuck at the discharge port into the separation box. This prevents the lithium battery debris from affecting the closure of the discharge port, which may damage the elastic telescopic plate and affect normal closure. At the same time, the rotation of the half gear will drive the L-shaped rod to move, which will push the slider upward and open the oil outlet of the oil tank to lubricate the rack. This prevents the parts from aging due to prolonged lack of lubrication, which would reduce working efficiency and affect the normal use of the machine.

[0024] 4. In this invention, the lithium battery and electrolyte are separated by the downward movement of the extruder. During the movement, the extruder pushes the filter plate to move left and right, spreading the lithium battery debris on the surface of the filter plate. This prevents the lithium battery debris from accumulating too high, which could cause some electrolyte to remain in the lithium battery during extrusion, potentially causing harm. At the same time, the downward movement of the extruder causes the filter plate to shake, which better shakes the electrolyte down, preventing the electrolyte from adhering to the filter holes and improving the separation effect.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] This embodiment proposes a recycling process for waste lithium batteries, including the following steps:

[0039] Step 1: The lithium battery is driven into the crushing box 2 by the conveying device 1, and the crusher 61 rotates to crush the lithium battery;

[0040] Step 2: As the crusher 61 rotates, it drives the short rod 62 to rotate. The short rod 62 rotates and contacts the inclined surface of the trapezoidal block 65. The short rod 62 pushes the trapezoidal block 65 to move closer to the conveying device 1, thus storing force on the elastic telescopic block 63.

[0041] Step 3: The trapezoidal block 65 moves toward the conveying device 1, which drives the push plate 64 to move toward the conveying device 1. The push plate 64 moves toward the conveying device 1 and squeezes the elastic telescopic block 63. When the short rod 62 disengages from the trapezoidal block 65, the elastic force of the elastic telescopic block 63 pushes the push plate 64 toward the middle of the crusher 61, pushing the lithium battery against the edge into the middle of the crusher 61 for crushing.

[0042] Step 4: Simultaneously, the push plate 64 moves towards the conveying device 1, causing the connecting rod 66 to move towards the conveying device 1. The moving of the connecting rod 66 towards the conveying device 1 pushes the baffle plate 67 to rotate, so that the lithium battery can indirectly enter the crusher 61 for crushing.

[0043] Example 2

[0044] like Figures 1-5 As shown, this embodiment proposes a recycling equipment for waste lithium batteries, including a conveying device 1, a crushing device, and an anti-jamming door device. A crushing box 2 is fixedly installed on the surface of the conveying device 1, a feeding box 3 is fixedly installed at the bottom of the crushing box 2, a separating box 4 is fixedly installed on the surface of the feeding box 3, and a crusher 5 is fixedly installed on the top of the separating box 4. The crushing device includes a crusher 61, a short rod 62, an elastic telescopic block 63, a pusher plate 64, a trapezoidal block 65, a connecting rod 66, and a baffle plate 67. The lithium batteries are driven into the crushing box 2 by the conveying device 1. The crusher 61 rotates to crush the lithium batteries. At the same time, the rotation of the crusher 61 drives the short rod 62 to rotate. The rotation of the short rod 62 will contact the inclined surface of the trapezoidal block 65. The short rod 62 will push the trapezoidal block 65 to move closer to the conveying device 1. The movement of the trapezoidal block 65 to move closer to the conveying device 1 will drive the pusher plate 64 to move closer to the conveying device 1. The movement will compress the elastic telescopic block 63. When the short rod 62 disengages from the trapezoidal block 65, it prevents the lithium battery from getting stuck on both sides of the crusher 61 and preventing it from being crushed in time, thus reducing the working efficiency of the crusher 61. The crusher 61 is fixedly installed on the surface of the crushing box 2. The short rod 62 is fixedly installed on the output end of the crusher 61. The elastic telescopic block 63 is fixedly installed on the inner wall of the crushing box 2. The push plate 64 is fixedly installed on the free end of the elastic telescopic block 63. The trapezoidal block 65 is fixedly installed on the bottom of the push plate 64. The connecting rod 66 is fixedly installed on the top of the push plate 64. The baffle plate 67 is rotatably installed on the inner wall of the conveying device 1. When the push plate 64 moves towards the conveying device 1, it will drive the connecting rod 66 to move towards the conveying device 1. When the connecting rod 66 moves towards the conveying device 1, it will push the baffle plate 67 to rotate, preventing too many lithium batteries from entering at once, which may increase the load on the crusher 61, potentially causing machine failure and reducing the machine's service life.

[0045] The push plate 64 does not contact the crusher 61. The trapezoidal block 65 has an inclined surface. A spring is provided between the baffle plate 67 and the conveying device 1. The push plate 64 does not contact the crusher 61 to prevent the crusher 61 from damaging the push plate 64 and causing machine damage. The spring drives the baffle plate 67 to reset, preventing the lithium batteries from being stuck and unable to enter the crusher 61 for crushing.

[0046] The anti-jamming device includes an inclined plate 71, an elastic telescopic plate 72, a fixing block 73, a fixing plate 74, a rotating wheel 75, a connecting rope 76, and a rotating plate 77. When the fixing block 73 moves downward, it contacts the fixing plate 74, which in turn pushes the fixing plate 74 downward. The downward movement of the fixing plate 74 causes the free end of the elastic telescopic plate 72 to move downward, closing the discharge port and preventing extrusion while continuing to feed. Lithium battery debris may fall above the extruder 5, requiring manual cleaning. This debris may also jam the extruder 5, potentially causing malfunctions and affecting work efficiency. The surface of the feeding box 3 has a discharge port. The inclined plate 71 is fixedly installed on the inner wall of the feeding box 3, and the elastic telescopic plate 72 is fixedly installed... The device is mounted on top of the discharge port. The fixing block 73 is installed at the output end of the extruder 5. The fixing plate 74 is fixedly installed at the free end of the elastic telescopic plate 72. The rotating wheel 75 is rotatably installed on the inner wall of the feeding box 3. The rotating plate 77 is rotatably installed on the surface of the inclined plate 71. One end of the connecting rope 76 is fixedly installed on the free end of the elastic telescopic plate 72, and the other end of the connecting rope 76 is fixedly installed on the surface of the rotating plate 77. At the same time, when the free end of the elastic telescopic plate 72 moves downward, it will drive one end of the connecting rope 76 to move downward. When one end of the connecting rope 76 moves downward, it will drive the other end of the connecting rope 76 to move upward. When the other end of the connecting rope 76 moves upward, it will drive the rotating plate 77 to rotate upward. This prevents lithium battery debris from getting stuck at the outlet and blocking the discharge port, which would prevent the discharge port from closing properly and affect the subsequent extrusion effect.

[0047] The connecting rope 76 is looped on the surface of the rotating wheel 75. A first torsion spring is provided between the rotating wheel 75 and the feeding box 3. A second torsion spring is provided between the rotating plate 77 and the inclined plate 71. The rotating wheel 75 is reset by the first torsion spring, and the rotating plate 77 is reset by the second torsion spring. The rotating plate 77 continuously blocks the lithium battery from entering the separation box 4.

[0048] In this embodiment, during operation, the lithium battery is driven into the crushing chamber 2 by the conveying device 1. The crusher 61 rotates to crush the lithium battery. Simultaneously, the rotation of the crusher 61 drives the short rod 62 to rotate. The short rod 62 contacts the inclined surface of the trapezoidal block 65, pushing the trapezoidal block 65 towards the conveying device 1. This movement of the trapezoidal block 65 towards the conveying device 1 causes the pusher plate 64 to move towards the conveying device 1. The pusher plate 64's movement towards the conveying device 1 compresses the elastic telescopic block 63. When the short rod 62 disengages from the trapezoidal block 65... Upon contact, the elastic force of the elastic telescopic block 63 will push the push plate 64 towards the center of the crusher 61 to prevent the lithium battery from getting stuck on both sides of the crusher 61 and not being crushed in time, thus reducing the working efficiency of the crusher 61. At the same time, the movement of the push plate 64 towards the conveying device 1 will drive the connecting rod 66 towards the conveying device 1. The movement of the connecting rod 66 towards the conveying device 1 will push the baffle plate 67 to rotate, preventing too many lithium batteries from entering at once, which may increase the load on the crusher 61, potentially causing machine failure and reducing the machine's service life.

[0049] When the extruder 5 moves downward to press the material, it will cause the fixed block 73 to move downward. The fixed block 73 will contact the fixed plate 74 and push the fixed plate 74 downward. The downward movement of the fixed plate 74 will cause the free end of the elastic telescopic plate 72 to move downward. The downward movement of the free end of the elastic telescopic plate 72 will close the discharge port, preventing lithium battery debris from falling onto the extruder 5 while extruding. This requires manual cleaning and may also cause the lithium battery debris to jam the extruder 5, potentially causing it to malfunction and affecting working efficiency. At the same time, the downward movement of the free end of the elastic telescopic plate 72 will cause one end of the connecting rope 76 to move downward. The downward movement of one end of the connecting rope 76 will cause the other end of the connecting rope 76 to move upward. The upward movement of the other end of the connecting rope 76 will cause the rotating plate 77 to rotate upward, preventing lithium battery debris from getting stuck at the outlet and blocking the discharge port, which would prevent the discharge port from closing properly and affect the subsequent extrusion effect.

[0050] Example 3

[0051] like Figures 1-9As shown, based on the same concept as Embodiment 2 above, this embodiment also proposes a pushing device and a separating device. The pushing device includes a half gear 81, a rack 82, an L-shaped push rod 83, a triangular bar 84, an oil tank 85, a slider 86, and an L-shaped rod 87. The upward rotation of the rotating plate 77 drives the half gear 81 to rotate upward. The upward rotation of the half gear 81 drives the rack 82 to move closer to the separating box 4. The movement of the rack 82 towards the separating box 4 drives the L-shaped push rod 83 to move closer to the separating box 4. The L-shaped push rod 83, moving closer to the separating box 4, contacts the surface of the triangular bar 84. The L-shaped push rod 83 pushes the triangular bar 84 closer to the separating box 4, pushing the lithium battery debris stuck at the outlet into the separating box 4. This prevents the lithium battery debris from affecting the closure of the outlet, which may damage the elastic telescopic plate 72 and affect normal closure. The bottom of the inclined plate 71... A groove is provided, with a half gear 81 fixedly installed at the bottom of the rotating plate 77, and a rack 82 slidably installed on the inner wall of the groove. The surfaces of the half gear 81 and the rack 82 mesh. An L-shaped push rod 83 is fixedly installed at the bottom of the rack 82, and a triangular strip 84 is slidably installed on the surface of the discharge port. An oil replenishment box 85 is fixedly installed on the inner wall of the groove, and an oil outlet is provided on the surface of the oil replenishment box 85. A slider 86 is slidably installed on the surface of the oil outlet, and an L-shaped rod 87 is fixedly installed on the top of the rack 82. When the rack 82 moves towards the separation box 4, it will drive the L-shaped rod 87 to move towards the separation box 4. When the L-shaped rod 87 moves towards the separation box 4, it will contact the inclined surface of the slider 86, and the L-shaped rod 87 will push the slider 86 to slide upward. When the slider 86 slides upward, it will open the oil outlet, lubricating the rack 82 and the half gear 81, preventing the parts from aging due to prolonged lack of lubrication, reducing working efficiency, and affecting the normal use of the machine.

[0052] A first spring is installed between the rack 82 and the groove, and a second spring is installed between the oil outlet and the slider 86. The L-shaped push rod 83 and the triangular bar 84 are in surface contact. A reset spring is installed between the triangular bar 84 and the outlet. The rack 82 is reset by the first spring, and the slider 86 is reset by the second spring to prevent the oil outlet from being open and causing waste. The triangular bar 84 is reset by the reset spring to prevent lithium battery fragments from getting stuck on the surface of the outlet.

[0053] The separation device includes an elastic telescopic rod 91, a filter plate 92, an L-shaped rod 93, an inclined block 94, a triangular block 95, a triangular slider 96, a round rod 97, and a square plate 98. When the L-shaped rod 93 moves downwards, it contacts the inclined surface of the inclined block 94, pushing the inclined block 94 towards the inner wall of the separation chamber 4. This movement of the inclined block 94 towards the inner wall of the separation chamber 4 causes the free end of the elastic telescopic rod 91 to move towards the inner wall of the separation chamber 4 to store force. When the L-shaped rod 93 disengages from the inclined block 94, the elastic force of the elastic telescopic rod 91 causes the filter plate 92 to reset. During the reset process, the lithium battery debris on the surface of the filter plate 92 is flattened to prevent excessive accumulation of lithium battery debris, which could lead to some electrolyte remaining in the lithium battery during extrusion by the extruder 5, potentially causing harm. The elastic telescopic rod 91 is fixedly installed on the inner wall of the separation chamber 4, and the filter plate 92 is fixedly installed on the inner wall of the elastic telescopic rod 97. The free end of the elastic telescopic rod 91, the L-shaped long rod 93 is fixedly installed at the output end of the extruder 5, the inclined block 94 is installed at the free end of the elastic telescopic rod 91, the triangular block 95 is fixedly installed on the surface of the L-shaped long rod 93, the triangular slider 96 is slidably installed on the surface of the filter plate 92, the round rod 97 is fixedly installed on the surface of the triangular slider 96, and the square plate 98 is fixedly installed on the surface of the filter plate 92. At the same time, the downward movement of the L-shaped long rod 93 will drive the triangular block 95 to move downward. The downward movement of the triangular block 95 will contact the inclined surface of the triangular slider 96, and the triangular block 95 will push the triangular slider 96 to move away from the L-shaped long rod 93. The movement of the triangular slider 96 away from the L-shaped long rod 93 will drive the round rod 97 to move away from the L-shaped long rod 93. During the movement of the round rod 97 away from the L-shaped long rod 93, it will contact the protrusion and generate vibration, which will better shake the electrolyte down, prevent the electrolyte from adhering to the filter holes, and improve the separation effect.

[0054] The L-shaped rod 93 and the inclined block 94 are in contact. A No. 3 spring is provided between the triangular slider 96 and the filter plate 92. A protrusion is fixedly installed on the surface of the square plate 98. The triangular slider 96 is driven by the No. 3 spring to reset, which can make the filter plate 92 vibrate multiple times, thus improving the separation effect.

[0055] In this embodiment, during operation, the rotating plate 77 rotates upward, causing the half gear 81 to rotate upward. The upward rotation of the half gear 81 causes the rack 82 to move closer to the separation box 4. This movement of the rack 82 towards the separation box 4 causes the L-shaped push rod 83 to move closer to the separation box 4. The L-shaped push rod 83, moving closer to the separation box 4, contacts the surface of the triangular strip 84, pushing the triangular strip 84 closer to the separation box 4. This pushes the lithium battery debris stuck at the outlet into the separation box 4, preventing lithium battery debris from being trapped inside. Debris can affect the closure of the discharge port, potentially damaging the elastic telescopic plate 72 and hindering normal closure. Simultaneously, the movement of the rack 82 towards the separation box 4 will cause the L-shaped rod 87 to move towards the separation box 4. The L-shaped rod 87 will then contact the inclined surface of the slider 86, pushing the slider 86 upward. This upward movement of the slider 86 will open the oil outlet, lubricating the rack 82 and the half gear 81. This prevents parts from aging due to prolonged lack of lubrication, reducing work efficiency and affecting the normal operation of the machine.

[0056] As the extruder 5 moves downward, it drives the L-shaped rod 93 downward. The L-shaped rod 93 then contacts the inclined surface of the inclined block 94, pushing the inclined block 94 towards the inner wall of the separation chamber 4. This movement of the inclined block 94 towards the inner wall of the separation chamber 4 causes the free end of the elastic telescopic rod 91 to move towards the inner wall of the separation chamber 4 to store force. When the L-shaped rod 93 disengages from the inclined block 94, the elastic force of the elastic telescopic rod 91 causes the filter plate 92 to reset. During the reset process, the lithium battery debris on the surface of the filter plate 92 is leveled, preventing excessive accumulation of lithium battery debris from causing the extruder 5 to malfunction. During the compression process, some electrolyte may remain in the lithium battery, potentially causing harm. Simultaneously, the downward movement of the L-shaped rod 93 causes the triangular block 95 to move downward. The downward movement of the triangular block 95 will contact the inclined surface of the triangular slider 96, which will push the triangular slider 96 away from the L-shaped rod 93. The movement of the triangular slider 96 away from the L-shaped rod 93 will cause the round rod 97 to move away from the L-shaped rod 93. During the movement of the round rod 97 away from the L-shaped rod 93, it will contact the protrusion and vibrate, better shaking off the electrolyte and preventing it from adhering to the filter pores, thus improving the separation effect.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
