Especially for lithium batteries, when thermal runaway occurs, it may cause fire or explosion accidents. Moreover, after the crushing is completed, the electrolyte and debris are mixed together, which will cause the recycled metal materials to be contaminated, which is a technical problem that makes recycling difficult. Summary of the invention

[0005] The used power battery is clamped and fixed by the clamping device, and then the rotating shaft drives the used power battery to move toward the rotating chamber, and then the rotating chamber is closed, so that a closed space is formed in the body, and the vacuum pump extracts the air in the body to the outside.

[0009] Before crushing, the sealing plate on the opening is in an open state, and the rotating shaft drives the clamping plate toward the opening, and then the hydraulic cylinder pushes the clamping plate to move toward the opening, so that the clamping plate extends from the opening and clamps the waste power battery. The electromagnet on the clamping plate is energized to generate magnetic force, which attracts the waste power battery, and the clamping plates on the clamping plate shrink and fix the two sides of the waste power battery; Then the hydraulic cylinder drives the clamping plate to contract, and the clamping plate drives the waste power battery to contract into the rotating chamber, and then the sealing plate closes the opening, so that the rotating chamber is in a closed environment, and the controller controls the rotating motor to drive, and the driving shaft of the rotating motor drives the hydraulic cylinder to rotate, and the hydraulic cylinder drives the clamping plate and the waste power battery to rotate when it rotates. During the rotation process, the controller controls the vacuum pump to evacuate the inside of the machine body, and extract the air inside the machine body to the outside, so that the inside of the machine body is in a state close to vacuum, so that the waste power battery can avoid contact with air in the subsequent crushing, causing certain safety problems, thereby improving the safety of the crushing of waste power batteries and ensuring the normal operation of the equipment.
[0010] Preferably, the crushing device includes a cutting assembly and a crushing assembly, the cutting assembly includes a plurality of cutting knives, the plurality of cutting knives are equidistantly arranged along the axis of the rotating chamber, the cutting knives are arc-shaped, a conveying groove is provided between two adjacent cutting knives, and a conveying port is provided on the side of the conveying groove away from the cutting knives.

[0013] Preferably, the separation chamber consists of a liquid chamber and a solid chamber, the liquid chamber is connected with the solid chamber, a conveyor belt is arranged in the separation chamber, the conveyor belt is driven by a transmission wheel, a conveying motor is arranged inside the separation chamber, the driving shaft of the conveying motor is connected to the transmission wheel, the conveyor belt consists of a transmission belt, a bracket and a plurality of funnels, and the upper and lower ends of the funnel are in a connected state; a ramp is arranged at the connection between the liquid chamber and the solid chamber.
[0014] Preferably, a crushing chamber is provided on the side of the protrusion away from the cutting knife, and two crushing rollers are provided in the crushing chamber. The two crushing rollers are arranged crosswise and rotate towards each other. The crushing rollers are composed of a plurality of crushing disks, and a plurality of crushing teeth are provided on the crushing disks.
[0015] Preferably, a collecting chamber is provided at the bottom of the crushing chamber, a filter plate is provided at the bottom of the crushing roller, the filter plate is in an inclined state, and the bottom of the filter plate is connected to the lowest point of the crushing roller.
[0016] When the air in the machine body is extracted, the rotating shaft continues to drive the waste power battery to move to the side close to the cutting knife. The controller adjusts the pushing stroke of the hydraulic cylinder according to the thickness of the waste power battery, so that the thickness of the cutting knife is equal to half the thickness of the waste power battery. By adjusting the pushing stroke, the pressure of the waste power battery being cut by the cutting knife is adjusted, thereby achieving the effect of automatic pressure regulation; At the same time, the controller controls the vibration motor to start, and the driving shaft of the vibration motor drives the cam to rotate. When the cam rotates, it drives the vibration column to move vertically, and the vibration column moves to the side close to the clamping plate. During the movement of the vibration column, the vibration column hits the clamping plate, so that the vibration generated by the impact is transmitted to the waste power battery through the clamping plate; When the rotating shaft drives the used power battery to contact the cutting knife, the cutting knife cuts the bottom of the used power battery. Since the cutting knife is in an arc shape, and the rotating shaft drives the used power battery to move in an arc shape, the cutting knife can completely cut the bottom of the used power battery. While the used power battery is being cut, the controller controls the air pump in the gas tank to start, and the air pump extracts the inert gas. The inert gas is transported to the gas delivery tank through the pipeline, and then transported to the gas outlet tank through the gas delivery tank, and finally sprayed out through the gas outlet tank. Since the thickness of the cutting knife is equal to half the thickness of the used power battery, the gas outlet tank is located inside the used power battery, and the sprayed inert gas is also located inside the used power battery, which further isolates the liquid in the battery from the air. The mass of inert gas is lighter than air. After the inert gas is filled into the waste power battery, the inert gas continuously pushes the liquid in the waste power battery to flow. At the same time, the vibration generated by the vibration column is transmitted to the waste power battery, so that the liquid in the battery is quickly separated from the waste power battery under the dual effects of the inert gas and vibration. The liquid in the battery flows out from the gap between the cutter and the waste power battery and flows into the conveying trough, thereby achieving the effect of separating the liquid before crushing, avoiding the mixing of liquid and metal fragments, which may cause the recycled metal materials to be contaminated and reduce the recycling value of the metal; the two adjacent cutters and the waste power battery form a triangular space, and the isolation of the inert gas makes the liquid in the battery further isolated from the air when it flows along the conveying trough, thereby reducing the contact time between the liquid in the battery and the air, and ensuring the safety of the liquid transportation in the battery; The liquid flows along the conveying trough to the conveying port, and is finally conveyed to the separation chamber through the conveying port. While the liquid is being conveyed, the waste power battery also moves toward the side close to the protrusion along the rotating shaft. When the waste power battery moves to the protrusion, the protrusion and the clamping plate cooperate with each other to squeeze the waste power battery, flatten the waste power battery, and facilitate subsequent crushing. During the squeezing process, the residual liquid in the waste power battery is squeezed out and conveyed to the separation chamber through the flow trough. After the liquid flows to the separation chamber, it first encounters the conveyor belt, and the liquid falls onto the funnel. Since the upper and lower ends of the funnel are in a connected state, the liquid flows smoothly from the funnel to the liquid chamber. When the liquid flows from the crushing trough into the separation chamber, debris may flow together, and the debris will be blocked by the funnel. The driving shaft of the conveying motor drives the transmission wheel to drive, and the transmission wheel drives the conveyor belt to rotate. The conveyor belt is transported from the liquid chamber to the solid chamber. The debris is separated from the conveyor belt in the solid chamber, thereby completing the separation of the liquid and the debris, and part of the liquid will flow to the liquid chamber again along the ramp; The squeezed waste power battery moves to the side close to the crushing chamber. During the movement, the controller controls the crushing roller to rotate, and the two crushing rollers rotate in opposite directions, so that the crushing roller drives the waste power battery to move from the crushing slot to the crushing chamber. When one end of the waste power battery contacts the crushing roller, the electromagnet and the clamping plate on the clamping plate are separated from the waste power battery, and the waste power battery moves under the squeezing action of the crushing roller. Several crushing teeth crush and decompose the waste power battery. The crushed and decomposed waste power battery falls to the surface of the filter plate. If the crushed size is smaller than the filter hole of the filter plate, it falls into the collection chamber at the bottom. If the crushed size is larger than the filter hole of the filter plate, since the filter plate is in an inclined state and the bottom of the filter plate is connected to the lowest point of the crushing roller, the large pieces of debris will be squeezed and crushed by the crushing roller at a lower position again, so that the size of the debris is smaller than the filter hole size of the filter plate. After the clamping plate is separated from the waste power battery, it moves to the bottom of the opening again under the rotation of the rotating shaft, and waits for the opening to open to clamp the next waste power battery.
[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. After the inert gas is filled into the waste power battery, the inert gas continuously pushes the liquid in the waste power battery to flow. At the same time, the vibration generated by the vibration column is transmitted to the waste power battery, so that the liquid in the battery is quickly separated from the waste power battery under the dual effects of the inert gas and vibration. The liquid in the battery flows out from the gap between the cutter and the waste power battery and flows into the conveying trough, thereby achieving the effect of separating the liquid before crushing, avoiding the mixing of liquid and metal fragments, which may cause the recycled metal materials to be contaminated and reduce the recycling value of the metal.
[0018] 2. The two adjacent cutting knives and the waste power battery form a triangular space. In addition, the inert gas isolates the liquid in the battery from the air when it flows along the conveying trough, thereby reducing the contact time between the liquid in the battery and the air and ensuring the safety of the liquid transportation in the battery.

[0028] Preferably, a crushing chamber 38 is provided on the side of the protrusion 35 away from the cutting knife 31, and two crushing rollers 39 are provided in the crushing chamber 38.

[0029] Preferably, a collecting chamber is provided at the bottom of the crushing chamber 38 , and a filter plate 40 is provided at the bottom of the crushing roller 39 . The filter plate 40 is in an inclined state, and the bottom of the filter plate 40 is connected to the lowest point of the crushing roller 39 .
[0030] Working principle of the present invention: Before crushing, the sealing plate on the opening 121 is in an open state, and the rotating shaft 14 drives the clamping plate 21 toward the opening 121, and then the hydraulic cylinder pushes the clamping plate 21 to move toward the opening 121, so that the clamping plate 21 extends from the opening 121 and clamps the waste power battery. The electromagnet on the clamping plate 21 is energized to generate magnetic force, which attracts the waste power battery, and the clamping plates on the clamping plate 21 shrink and fix the two sides of the waste power battery; Then the hydraulic cylinder drives the clamping plate 21 to contract, and the clamping plate 21 drives the waste power battery to contract into the rotating chamber 12, and then the sealing plate closes the opening 121, so that the rotating chamber 12 is in a closed environment, and the controller controls the rotating motor to drive, and the driving shaft of the rotating motor drives the hydraulic cylinder to rotate, and the hydraulic cylinder drives the clamping plate 21 and the waste power battery to rotate when rotating. During the rotation, the controller controls the vacuum pump to evacuate the inside of the body 1, and extracts the air inside the body 1 to the outside, so that the inside of the body 1 is in a state close to vacuum, so that the waste power battery can avoid contact with air during subsequent crushing.
[0031] When the air in the body 1 is extracted, the rotating shaft 14 continues to drive the waste power battery to move toward the side close to the cutting knife 31. The controller adjusts the pushing stroke of the hydraulic cylinder according to the thickness of the waste power battery, so that the thickness of the cutting knife 31 is equal to half the thickness of the waste power battery. By adjusting the pushing stroke, the pressure of the waste power battery being cut by the cutting knife 31 is adjusted, thereby achieving the effect of automatic pressure regulation. At the same time, the controller controls the vibration motor to start, and the driving shaft of the vibration motor drives the cam 24 to rotate. When the cam 24 rotates, it drives the vibration column 23 to move vertically, and the vibration column 23 moves to the side close to the clamping plate 21. During the movement of the vibration column 23, the vibration column 23 impacts the clamping plate 21, so that the vibration generated by the impact is transmitted to the waste power battery through the clamping plate 21; When the rotating shaft 14 drives the used power battery to contact the cutting knife 31, the cutting knife 31 cuts the bottom of the used power battery. Since the cutting knife 31 is in an arc shape, and the rotating shaft 14 drives the used power battery to move in an arc shape, the cutting knife 31 can completely cut the bottom of the used power battery. When the used power battery is cut, the controller controls the air pump in the gas tank to start, and the air pump extracts the inert gas. The inert gas is transported to the gas delivery groove 311 through the pipeline, and then transported to the gas outlet groove 312 through the gas delivery groove 311, and finally ejected through the gas outlet groove 312. Since the thickness of the cutting knife 31 is equal to half the thickness of the used power battery, the gas outlet groove 312 is located inside the used power battery, and the ejected inert gas is also located inside the used power battery, further isolating the liquid in the battery from the air. The mass of the inert gas is lighter than that of the air. After the inert gas is filled into the waste power battery, the inert gas continuously pushes the liquid in the waste power battery to flow. At the same time, the vibration generated by the vibration column 23 is transmitted to the waste power battery, so that the liquid in the battery is quickly separated from the waste power battery under the dual effects of the inert gas and the vibration. The liquid in the battery flows out from the gap between the cutting blade 31 and the waste power battery and flows into the conveying trough 32, thereby achieving the effect of separating the liquid before crushing and avoiding the mixing of the liquid and the metal fragments. The two adjacent cutting blades 31 and the waste power battery form a triangular space, and the isolation of the inert gas makes the liquid in the battery further isolated from the air when flowing along the conveying trough 32. The liquid flows along the conveying groove 32 to the conveying port 33, and is finally conveyed to the separation chamber 34 through the conveying port 33. While the liquid is being conveyed, the used power battery also moves along the rotating shaft 14 to the side close to the protrusion 35. When the used power battery moves to the protrusion 35, the protrusion 35 and the clamping plate 21 cooperate with each other to squeeze the used power battery and flatten the used power battery for subsequent crushing. In the squeezing process, the residual liquid in the used power battery is squeezed out and conveyed to the separation chamber 34 through the flow groove 36. When the liquid flows to the separation chamber 34, it first encounters the conveyor belt 37, and the liquid falls off. The liquid falls onto the funnel 371. Since the upper and lower ends of the funnel 371 are in a connected state, the liquid flows smoothly from the funnel 371 to the liquid chamber 341. When the liquid flows from the crushing groove 13 into the separation chamber 34, debris may flow together, and the debris will be blocked by the funnel 371. The driving shaft of the conveying motor drives the transmission wheel, and the transmission wheel drives the conveyor belt 37 to rotate. The conveyor belt 37 is transported from the liquid chamber 341 to the solid chamber 342. The debris is separated from the conveyor belt 37 in the solid chamber 342, thereby completing the separation of the liquid and the debris. Part of the liquid will flow back to the liquid chamber 341 along the ramp 343. The squeezed waste power battery moves to the side close to the crushing chamber 38. During the movement, the controller controls the crushing roller 39 to rotate, and the two crushing rollers 39 rotate in opposite directions, so that the crushing roller 39 drives the waste power battery to move from the crushing slot 13 to the crushing chamber 38. When one end of the waste power battery contacts the crushing roller 39, the electromagnet and the clamping plate on the clamping plate 21 are separated from the waste power battery, and the waste power battery moves under the squeezing action of the crushing roller 39. A plurality of crushing teeth 391 crush and decompose the waste power battery. The crushed and decomposed waste power battery falls onto the surface of the filter plate 40. If the crushed size is smaller than the filter hole of the filter plate 40, it falls into the collection chamber at the bottom. If the crushed size is larger than the filter hole of the filter plate 40, since the filter plate 40 is in an inclined state and the bottom of the filter plate 40 is connected to the lowest point of the crushing roller 39, the large pieces of debris will be squeezed and crushed by the crushing roller 39 at a lower position again, so that the size of the debris is smaller than the filter hole size of the filter plate 40. After the clamping plate 21 is separated from the waste power battery, it moves to the bottom of the opening 121 again under the rotation of the rotating shaft 14, and waits for the opening 121 to open before clamping the next waste power battery.
