Description

Technical Field

[0001] This invention relates to the field of battery dismantling and recycling technology, specifically to a power battery dismantling and recycling device. Background Technology

[0002] With the rapid development of electric vehicles and energy storage devices, the use of power batteries has increased dramatically, making their dismantling and recycling a crucial link in resource recycling and environmental protection. Power batteries contain a large amount of valuable metal materials and harmful electrolytes; improper handling can lead to resource waste and environmental pollution. Currently, electrolyte recovery during power battery recycling is often incomplete. Existing technologies often employ simple crushing and centrifugal separation methods, but these suffer from low recovery efficiency, high electrolyte residue levels, and the potential for secondary pollution. Furthermore, battery fragments tend to accumulate during centrifugation, potentially obscuring the internal electrolyte and hindering complete separation, resulting in unsatisfactory recycling outcomes. Therefore, there is an urgent need for a highly efficient and thorough power battery dismantling and recycling device that can improve electrolyte recovery rates, reduce environmental pollution, and enhance overall recycling efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a power battery dismantling and recycling device, which solves the problems mentioned above.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a power battery dismantling and recycling device, including a chassis, a feeding hopper and a discharging box, wherein the feeding hopper is connected to the discharge port of an external crushing device, and the inner cavity of the chassis is provided with a centrifugal component and a vibration component, wherein the centrifugal component is connected to the bottom of the feeding hopper and the top of the discharging box respectively through a connecting component; The centrifuge assembly includes an upper slide plate and a lower slide plate that slide up and down inside the casing. One side of each of the upper and lower slide plates is rotatably connected to a centrifuge tube driven by a power mechanism. The middle section of the centrifuge tube is provided with a mesh. The connecting assembly includes a connecting ring fixed at one end of the inner cavity of the machine casing and rotatably connected to the centrifuge tube. The other end of the connecting ring is connected to the feed hopper and the discharge box respectively through a gold wire flexible tube. The inner cavity of the connecting ring is rotatably connected to a switch plate driven by a motor. The inner cavity of the connecting ring of the upper connecting assembly is provided with an air outlet ring that is connected to the air outlet pipe of an external fan. The air outlet of the air outlet ring faces the inner cavity of the centrifuge tube. The vibration assembly includes a collar fixed inside the chassis cavity, and a moving rod driven by a drive mechanism is slidably connected to the inner cavity of the collar. The two ends of the moving rod are fixedly connected to the opposite sides of the upper and lower sliding plates, respectively.

[0005] As a further aspect of the present invention: the power mechanism includes a motor fixed to the surface of the upper slide plate, a drive gear fixedly connected to the output shaft end of the motor, and a gear ring fixedly connected to the surface of the centrifuge tube to mesh with the drive gear. The motor drives the drive gear to rotate, which in turn drives the gear ring to rotate, causing the centrifuge tube to rotate on the surfaces of the upper and lower slide plates, thus throwing out the internal electrolyte.

[0006] As a further aspect of the present invention: the driving mechanism includes a power arm that is rotatably mounted in the inner cavity of the chassis by a motor. A connecting rod is rotatably connected to the end of the power arm, and the other end of the connecting rod is rotatably connected to the surface of the middle section of the moving rod. In use, the motor drives the power arm to rotate, and then the connecting rod drives the moving rod to move up and down reciprocally, which drives the upper and lower slide plates to move up and down synchronously, and drives the centrifuge tube to move up and down to vibrate and shake the internal fragments, exposing the electrolyte that may be blocked inside for centrifugation.

[0007] As a further aspect of the present invention: an elastic sealing gasket is fixedly connected to the surface of the connecting ring of the lower connecting component, and the elastic sealing gasket is fixedly connected to the inner cavity of the chassis, thereby sealing the internal electrolyte and collecting it.

[0008] As a further aspect of the present invention: the bottom of the elastic sealing gasket is connected to an output pipe extending to the outside of the chassis.

[0009] As a further aspect of the present invention: a negative pressure pipe is connected to the top of the inner cavity of the chassis for extracting the atomized electrolyte inside.

[0010] Compared with the prior art, the present invention has the following advantages: By combining centrifugal and vibration components, the electrolyte in battery fragments can be effectively separated. The centrifugal component includes an upper and lower slide plate and a centrifuge tube. Centrifugal force is used to throw the electrolyte out of the fragments. At the same time, the vibration component drives the centrifuge tube to vibrate through reciprocating motion, exposing the electrolyte that is blocked inside the fragments, thus further improving the efficiency and thoroughness of electrolyte recovery.

[0011] The connecting assembly uses a connecting ring and a gold wire hose to connect the feed hopper and the discharge box, ensuring the sealing and flexibility of material conveying, reducing the risk of electrolyte leakage, and controlling the material flow through a switch panel, making operation simple.

[0012] The power mechanism drives the centrifuge tube to rotate via a motor-driven drive gear and gear ring, achieving efficient centrifugal separation. The drive mechanism drives the moving rod to move up and down via a power arm and connecting rod, achieving synchronous vibration. The structure is stable and the power transmission is reliable.

[0013] The air outlet ring allows air to be blown into the centrifuge tube through the fan outlet pipe, which helps dry the fragments, reduces electrolyte residue, and improves the recycling quality.

[0014] The design of the elastic sealing gasket and negative pressure pipeline enhances the sealing and collection capacity of the device. The elastic sealing gasket prevents electrolyte leakage, and the negative pressure pipeline can extract the atomized electrolyte, further reducing the risk of environmental pollution. The overall device has a compact structure and is suitable for industrial applications.

[0015] Through the synergistic action of the centrifugal and vibration components, the rotatable centrifugal tube, driven by a power mechanism, generates centrifugal force to separate the electrolyte. Simultaneously, the drive mechanism, via a moving rod, causes the upper and lower sliding plates to vibrate synchronously, effectively exposing and dislodging residual electrolyte trapped inside the battery fragments, significantly improving recycling efficiency and thoroughness. The connecting component uses a connecting ring and a gold-wire flexible tube to ensure the sealing of material transport. Combined with the air-assisted drying function of the air outlet ring and the collection design of the elastic sealing gasket and negative pressure pipeline, the risk of electrolyte leakage and environmental pollution is significantly reduced, achieving safe, efficient, and comprehensive recovery of electrolyte during the dismantling of power batteries.

The other end of the connecting ring 6 is connected to the feed hopper 2 and the discharge box respectively through a gold wire flexible tube 10. The inner cavity of the connecting ring 6 is rotatably connected to a switch plate 9 driven by a motor. The inner cavity of the connecting ring 6 of the upper connecting assembly is provided with an air outlet ring 7 that is connected to the air outlet pipe 8 of the external fan. The air outlet of the air outlet ring 7 faces the inner cavity of the centrifuge tube 12. The vibration assembly includes a collar 18 fixed in the inner cavity of the chassis 1. A motion rod 19 driven by a drive mechanism is slidably connected to the inner cavity of the collar 18. The two ends of the motion rod 19 are fixedly connected to the opposite sides of the upper slide plate 3 and the lower slide plate 4, respectively.

[0020] The power mechanism includes a motor fixed to the surface of the upper slide plate 3. The output shaft of the motor is fixedly connected to a drive gear 14. The surface of the centrifuge tube 12 is fixedly connected to a gear ring 15 that meshes with the drive gear 14. The motor drives the drive gear 14 to rotate, which in turn drives the gear ring 15 to rotate, causing the centrifuge tube 12 to rotate on the surfaces of the upper slide plate 3 and the lower slide plate 4, thus throwing out the internal electrolyte.

[0021] The drive mechanism includes a power arm 16 that is driven to rotate within the inner cavity of the casing 1 by a motor. A connecting rod 17 is rotatably connected to the end of the power arm 16. The other end of the connecting rod 17 is rotatably connected to the surface of the middle section of the moving rod 19. In use, the motor drives the power arm 16 to rotate, and then the connecting rod 17 drives the moving rod 19 to move up and down reciprocally, which drives the upper slide plate 3 and the lower slide plate 4 to move up and down synchronously, and drives the centrifuge tube 12 to move up and down to vibrate and shake the internal fragments, exposing the electrolyte that may be blocked inside for centrifugation.

[0022] An elastic sealing gasket 20 is fixedly connected to the surface of the connecting ring 6 of the lower connecting component. The elastic sealing gasket 20 is fixedly connected to the inner cavity of the chassis 1 and is used to seal the internal electrolyte.

[0023] The bottom of the elastic sealing gasket 20 is connected to an output pipe extending to the outside of the chassis 1.

[0024] The top of the inner cavity of the chassis 1 is connected to a negative pressure pipe, which is used to extract the atomized electrolyte inside.

[0025] In use, the working principle of this invention is as follows: After the power battery is processed by the crushing equipment, the fragments enter the device through the feed hopper 2, which is connected to the discharge port of the external crushing equipment. The material enters the centrifugal assembly through the connecting assembly, which includes a connecting ring 6 and a gold wire hose 10. The connecting ring 6 controls the material flow through a switch plate 9. The upper connecting ring 6 is connected to the feed hopper 2, and the lower connecting ring 6 is connected to the discharge box.

[0026] The centrifuge assembly includes an upper slide plate 3 and a lower slide plate 4, which can slide up and down inside the casing 1. A centrifuge tube 12 is rotatably connected to one side of the upper slide plate 3 and the lower slide plate 4. A mesh 13 is opened in the middle section of the centrifuge tube 12. The power mechanism drives the drive gear 14 to rotate through a motor. The drive gear 14 meshes with the gear ring 15, driving the centrifuge tube 12 to rotate. Battery fragments are subjected to centrifugal force inside the centrifuge tube 12, and the electrolyte is thrown out through the mesh 13, achieving preliminary separation.

[0027] Simultaneously, the vibration assembly begins operation. This assembly includes a collar 18 and a moving rod 19, with both ends of the moving rod 19 fixedly connected to the upper slide plate 3 and the lower slide plate 4. The drive mechanism drives the power arm 16 to rotate via a motor. The power arm 16, through a connecting rod 17, drives the moving rod 19 to reciprocate up and down within the collar 18, thereby causing the upper slide plate 3 and the lower slide plate 4 to move up and down synchronously, causing the centrifuge tube 12 to vibrate. This vibration process exposes the electrolyte trapped inside the battery fragments, allowing for further separation by centrifugal force and improving the recovery rate.

[0028] During centrifugation and shaking, the air outlet ring 7 blows air into the inner cavity of the centrifuge tube 12 through the fan outlet pipe 8 to assist in drying the fragments and reduce electrolyte residue. The separated electrolyte is collected outside the casing 1 through the elastic sealing gasket 20 of the lower connecting component and the output pipe, while the negative pressure pipe at the top of the inner cavity of the casing 1 can extract the atomized electrolyte to ensure environmental safety. Finally, the processed battery fragments are discharged through the discharge box, completing the recycling process. The entire device achieves efficient and thorough electrolyte recovery through the synergistic effect of centrifugation and shaking.
