Description

Technical Field

[0001] This application relates to the field of battery recycling technology, for example to a device for separating the positive electrode current collector of a battery by a high-voltage pulse. Background Technology

[0002] In waste battery recycling, it is often necessary to separate the positive electrode active material from the aluminum foil on the positive electrode current collector to facilitate its recovery. Studies have shown that placing the positive electrode current collector in water and applying a 25kV high-voltage pulse to it can separate most of the positive electrode active material from the aluminum foil surface, while the aluminum foil retains its shape.

[0003] Currently, the high-voltage pulse separation device for positive electrode current collectors in batteries includes an electrical control box, a steel drum, and a robotic arm. The steel drum has a socket inside, the robotic arm has a fixing plate, and the electrical control box is located outside the steel drum. The fixing plate is connected to the positive terminal of the electrical control box via a positive high-voltage wiring harness, and the socket is connected to the negative terminal of the electrical control box via a negative high-voltage wiring harness. In use, water is poured into the steel drum, and one end of the positive electrode current collector to be processed is clamped in the fixing plate on the robotic arm. The robotic arm immerses the positive electrode current collector in the water in the steel drum and inserts the other end of the positive electrode current collector into the socket, making the two ends of the positive electrode current collector connected to the positive and negative terminals of the electrical control box, respectively. Under the action of a high-voltage pulse current, the positive electrode active material on the positive electrode current collector is separated from the aluminum foil. However, this device can only process one positive electrode current collector at a time, resulting in low efficiency. Furthermore, subsequent sorting of the positive electrode active material and aluminum foil particles in the water is required, which is not conducive to the recovery of the positive electrode active material and aluminum foil. Summary of the Invention

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0036] like Figures 1 to 7As shown, this application provides a device for separating the positive electrode current collector of a high-voltage pulse-discharge battery, including a processing tank 1, a rotating platform 3, a pulse discharge component (not shown in the figure), a collection tank 2, and a pressure plate 4. The top of the processing tank 1 has an opening. The rotating platform 3 is vertically and vertically disposed in the processing tank 1, and the rotating platform 3 can rotate relative to the processing tank 1 about its own axis. In this example, the cross-section of the processing tank 1 is circular, and the axis of the processing tank 1 coincides with the axis of the rotating platform 3. Multiple current collector placement positions (not shown in the figure) are provided on the upper side of the rotating platform 3. The current collector placement positions are used to place the positive electrode current collector 100 to be processed. All the current collector placement positions are distributed at intervals around the axis of the rotating platform 3. Each current collector placement position is provided with a positive electrode contact 301 and a negative electrode contact 302. The positive electrode contact 301 and the negative electrode contact 302 in each current collector placement position are distributed at intervals. The rotating platform 3 is provided with a first hollow structure 312 through its thickness direction. In this example, the length of each current collector placement position extends along the radial direction of the rotary table 3, and the positive electrode contact 301 and negative electrode contact 302 in each current collector placement position are spaced apart along the radial direction of the rotary table 3. A collection bucket 2 is arranged around the outer periphery of the processing bucket 1, and is used to collect the aluminum foil separated from the positive current collector 100. A pulse discharge component is disposed outside the processing bucket 1; the positive output terminal of the pulse discharge component can be electrically connected to each positive electrode contact 301, and the negative output terminal of the pulse discharge component can be electrically connected to each negative electrode contact 302. A pressure plate 4 is vertically and vertically mounted on the upper side of the rotary table 3, and the pressure plate 4 is used to selectively press each positive current collector 100 on the rotary table 3. The rated voltage of the pulse discharge component is 25kV. In actual implementation, the treatment tank 1 is filled with a set amount of water. The positive current collector 100 is submerged in the water in the treatment tank 1. The 25kV high voltage pulse can separate most of the positive active material on the positive current collector 100 from the aluminum foil surface and keep the aluminum foil in its shape.

[0037] The rotating platform 3 has a first position and a second position. The first position is below the second position. The rotating platform 3 can move up and down between the first position and the second position. The first position is below the liquid surface in the treatment tank 1, and the second position is above the treatment tank 1. When the rotating platform 3 is in the first position, it is submerged in the water in the treatment tank 1. When the rotating platform 3 is in the second position, it is above the treatment tank 1. The rotating platform 3 is vertically and flexibly positioned within the processing tank 1. When the rotating platform 3 descends to the first position, the positive output terminal of the pulse discharge component is electrically connected to each positive contact 301, and the negative output terminal of the pulse discharge component is electrically connected to each negative contact 302. The rotating platform 3 and each positive current collector 100 on the rotating platform 3 are immersed in the water of the processing tank 1. A high-voltage pulse current is conducted to each positive current collector 100 through the pulse discharge component. Under the action of the high-voltage pulse, the positive active material of each positive current collector 100 on the rotating platform 3 is separated from the aluminum foil. Since the rotating platform 3 has a first perforated structure 312 extending through its thickness direction, the separated positive active material can pass through the first perforation. Structure 312 falls to the bottom of the processing tank 1, while the aluminum foil is pressed against the rotating platform 3. This achieves the simultaneous separation of multiple positive current collectors 100, improving the processing efficiency of the positive current collector 100 and facilitating the subsequent separate collection of the positive active material and aluminum foil. When the rotating platform 3 rises to the second position, the rotating platform 3 drives the separated aluminum foil through the opening end of the processing tank 1 and protrudes from the top of the processing tank 1. The pressure plate 4 is removed from the rotating platform 3, and the rotating platform 3 is rotated relative to the processing tank 1. Under the action of centrifugal force, each aluminum foil on the rotating platform 3 is thrown out into the collection tank 2. The aluminum foil separated from the positive current collector 100 is collected through the collection tank 2, realizing the batch collection of multiple aluminum foils. Furthermore, multiple current collector placement positions are provided on the upper side of the rotating table 3, each capable of accommodating one positive current collector 100 to be processed. This allows multiple positive current collectors 100 to be processed simultaneously on the rotating table 3, ensuring the separation efficiency of the positive current collectors 100. A liftable pressure plate 4 is provided, which can press the multiple positive current collectors 100 on the rotating table 3 together, ensuring that both ends of the positive current collector 100 are in close contact with the positive contact 301 and the negative contact 302, respectively. This ensures electrical conductivity between the positive current collector 100 and the high-voltage pulse component, improving the reliability of the high-voltage pulse separation device for the positive current collector of the battery. This high-voltage pulse separation device for the positive current collector of the battery, through the cooperation of the rotating table 3 and the pressure plate 4, can simultaneously separate the positive current collectors 100, and the separated aluminum foil can be collected in batches through the collection bucket 2, greatly improving the processing efficiency of the positive current collectors 100 and ensuring high reliability.

[0038] Reference Figure 4 and Figure 5The rotating platform 3 includes a frustum 303 and an outer ring 304 spaced around the outer periphery of the frustum 303. A first reinforcing ring 305 and a second reinforcing ring 306 are spaced between the outer ring 304 and the frustum 303. The first reinforcing ring 305 is close to the outer ring 304, and the second reinforcing ring 306 is close to the frustum 303. A plurality of reinforcing plates 308 are connected between the outer ring 304 and the first reinforcing ring 305. The plurality of reinforcing plates 308 are spaced around the outer periphery of the first reinforcing ring 305. The first reinforcing ring 305 and the second reinforcing ring 306, as well as the second reinforcing ring 306 and the frustum 303, are all connected by a plurality of reinforcing rods 307. Each reinforcing plate 308 is provided with a positive electrode contact 301. Multiple negative electrode contacts 302 are arranged at intervals around the axis of the frustum 303. The negative electrode contacts 302 correspond one-to-one with the positive electrode contacts 301. The gap between the first reinforcing ring 305 and the second reinforcing ring 306, the gap between the second reinforcing ring 306 and the frustum 303, and the gap between the outer ring 304 and the first reinforcing ring 305 form a first hollow structure 312. In use, the two ends of the positive electrode current collector 100 are placed on the reinforcing plate 308 and the frustum 303. The positive electrode active material separated by the positive electrode current collector 100 on the rotating table 3 can fall from the first hollow structure 312 located between the reinforcing plate 308 and the frustum 303 to the bottom of the processing tank 1 to collect the positive electrode active material in the processing tank.

[0039] Continue to refer to Figure 4 and Figure 5 In order to increase the probability of the positive electrode active material falling from the rotating table 3 to the bottom of the processing tank 1, the reinforcing plate 308 and the frustum 303 are provided with through holes 309 on both sides of each negative electrode contact 302. In this way, the separated positive electrode active material can also fall to the bottom of the processing tank 1 through the through holes 309.

[0040] Reference Figures 1 to 3The inner wall of the processing tank 1 is provided with a positive conductive block 101 and a negative conductive block 102 protruding from it. The positive conductive block 101 is electrically connected to the positive output terminal of the pulse discharge component through a first high-voltage wire harness (not shown in the figure), and the negative conductive block 102 is electrically connected to the negative output terminal of the pulse discharge component through a second high-voltage wire harness (not shown in the figure). The lower side of the rotating table 3 is provided with a first conductive block 310 and a second conductive block 311 protruding from it. The first conductive block 310 can abut against the positive conductive block 101, and the second conductive block 311 can abut against the negative conductive block 102. The first conductive block 310 is electrically connected to each positive contact 301 on the rotating table 3, and the second conductive block 311 is electrically connected to each negative contact 302 on the rotating table 3. Specifically, the first conductive block 310 can be electrically connected to each positive contact 301 through a wire or a circuit board, and the second conductive block 311 can be electrically connected to each negative contact 302 through a wire or a circuit board. It is understandable that when the rotating platform 3 is in the first position, the first conductive block 310 on the lower side of the rotating platform 3 abuts against the positive electrode conductive block 101, and the second conductive block 311 on the lower side of the rotating platform 3 abuts against the negative electrode conductive block 102, so that the positive electrode current collector 100 in the current collector placement position on the rotating platform 3 is electrically connected to the pulse discharge component. When the rotating platform 3 is in the second position, the first conductive block 310 and the second conductive block 311 both rise above the positive electrode conductive block 101 and the negative electrode conductive block 102. At this time, the first conductive block 310 does not contact the positive electrode conductive block 101 and the second conductive block 311 does not contact the negative electrode conductive block 102. In this way, when the rotating platform 3 rotates relative to the processing tank 1, the positive electrode conductive block 101 and the negative electrode conductive block 102 will not interfere with the position of the rotating platform 3.

[0041] Continue to refer to Figures 1 to 3 A first lifting cylinder 6 is connected to the lower side of the rotary table 3. The first lifting cylinder 6 is used to drive the rotary table 3 to rise and fall, and provides power for the rising and falling of the rotary table 3. A second lifting cylinder 7 is connected to the pressure plate 4. The second lifting cylinder 7 is used to drive the pressure plate 4 to rise and fall relative to the rotary table 3. The second lifting cylinder 7 provides power for the rising and falling of the pressure plate 4. Specifically, both the first lifting cylinder 6 and the second lifting cylinder 7 are adjustable-stroke lifting cylinders. In this example, a fixed frame 11 is fixedly installed above the pressure plate 4. The second lifting cylinder 7 has a cylinder body and a telescopic rod that can extend and retract relative to the cylinder body. The cylinder body of the second lifting cylinder 7 is connected to the fixed frame 11, and the telescopic rod of the second lifting cylinder 7 is connected to the pressure plate 4. The fixed frame 11 provides positioning and support for the second lifting cylinder 7.

[0042] Specifically, the first lifting cylinder 6 has a cylinder body and a telescopic rod that can extend and retract relative to the cylinder body. In one example, the cylinder body of the first lifting cylinder 6 is fixedly installed at the bottom of the processing tank 1, one end of the telescopic rod of the first lifting cylinder 6 is connected to the cylinder body, and the other end is connected to the rotating table 3 through a rotating component (e.g., a rotating motor). The rotating component drives the rotating table 3 to rotate relative to the first lifting cylinder 6. In another example, the rotating component can also be installed at the bottom of the processing tank 1 and connected to the first lifting cylinder 6. The rotation of the rotating component drives the first lifting cylinder 6 and the rotating table 3 to rotate.

[0043] Reference Figures 1 to 3 as well as Figure 7 Multiple sets of clamping assemblies protrude from the side of the pressure plate 4 facing the rotary table 3. Each clamping assembly corresponds to a current collector placement position. Each set of clamping assemblies includes two clamping blocks 401, which correspond to the positive contact 301 and the negative contact 302, respectively. The clamping blocks 401 are used to clamp the positive current collector 100 in the current collector placement position. The clamping blocks 401 of each set of clamping assemblies protrude from the lower side of the pressure plate 4. When the clamping assemblies clamp the positive current collector 100 in the current collector placement position, the two clamping blocks 401 in each set of clamping assemblies clamp the positive current collector 100 at the position directly opposite the positive contact 301 and the negative contact 302. This design, on the one hand, ensures good contact between the positive current collector 100 and the positive and negative contacts 302 through the cooperation of the two clamping blocks 401 with the positive and negative contacts 301; on the other hand… Since both pressure blocks 401 protrude from the side of the pressure plate 4 facing the positive current collector 100, when the positive current collector 100 is pressed on the rotating table 3, there is a certain gap between the part of the positive current collector 100 located between the two pressure blocks 401 and the pressure plate 4. The positive active material separated from the positive current collector 100 can be discharged from this gap to the area outside the current collector placement position, reducing the contact area between the pressure plate 4 and the positive current collector 100, which is beneficial to the separation of the positive active material from the aluminum foil.

[0044] For example, refer to Figure 6 The pressure plate 4 is provided with a second hollow structure 402, which extends through both sides of the pressure plate 4 in the thickness direction. By providing the second hollow structure 402 on the pressure plate 4, the water flow in the treatment tank 1 can pass through the second hollow structure 402 on the pressure plate 4 during the lifting and lowering of the pressure plate 4 in the water, reducing the resistance of the water flow to the pressure plate 4 and facilitating the lifting and lowering of the pressure plate 4. In addition, when the pressure plate 4 rises together with the rotating platform 3, the positive electrode active material separated by the positive electrode current collector 100 can be discharged to the outside of the pressure plate 4 with the water flow through the second hollow structure 402. Under the water flow, the positive electrode active material can be carried to the bottom of the rotating platform 3, thus effectively reducing the positive electrode active material thrown out of the treatment tank 1 during the rotation of the rotating platform 3.

[0045] Reference Figures 1 to 3 , Figure 6 and Figure 7 A spraying component 5 is provided on the side of the pressure plate 4 facing the rotary table 3. The spraying component 5 includes a boss 501 and multiple sets of nozzles. One end of the boss 501 is mounted on the pressure plate 4, and the other end protrudes towards the rotary table 3. The multiple sets of nozzles are arranged around the outer periphery of the boss 501. Each set of nozzles can spray high-pressure gas and / or high-pressure liquid in the radial direction of the rotary table 3. In this example, each set of nozzles is configured to spray high-pressure liquid in the radial direction of the rotary table 3. It is understood that when the positive electrode pressure block 401 and the negative electrode pressure block 401 on the pressure plate 4 press against the positive electrode current collector 100, the lower end of the boss 501 needs to avoid the rotary table 3 to prevent the boss 501 from interfering with the rotary table 3 and affecting the pressure plate 4's pressing against the positive electrode current collector 100. In actual implementation, the rotating platform 3 also has a third position, located between the first and second positions, and above the liquid surface in the processing tank 1. After the positive electrode current collector 100 is separated on the rotating platform 3, the rotating platform 3 and the pressure plate 4 rise from the first position to the third position. Each nozzle group sprays high-pressure liquid in the radial direction of the rotating platform 3, using the high-pressure liquid to spray out the positive electrode active material remaining between the pressure plate 4 and the rotating platform 3. Then, the rotating platform 3 is raised to the second position. The spraying component 5 allows the nozzle group to spray high-pressure liquid into the area between the pressure plate 4 and the rotating platform 3 before the rotating platform 3 rises to the second position, effectively reducing the amount of positive electrode active material remaining on the rotating platform 3 and lowering the probability of the positive electrode active material being thrown out of the collection tank 2. Of course, in other examples, each nozzle group can also be set to spray high-pressure gas in the radial direction of the rotating platform 3, or each nozzle group can simultaneously spray high-pressure gas and high-pressure liquid in the radial direction of the rotating platform 3.

[0046] To prevent the positive contact 301, negative contact 302, positive pressure block 401 and negative pressure block 401 from blocking the high-pressure gas and / or high-pressure liquid ejected by the nozzle assembly, a nozzle assembly is set between two adjacent collector placement positions.

[0047] In this example, each nozzle group includes two nozzles 502. The two nozzles 502 in each nozzle group are spaced apart along the height direction of the boss 501. The two nozzles 502 expand the spray area of ​​the nozzle group and reduce the spray blind zone.

[0048] In actual implementation, the number of nozzles 502 in each nozzle group can be flexibly adjusted as needed. For example, the number of nozzles 502 in the nozzle group can be one, two or three, etc. There is no limit to the number of nozzles 502 in each nozzle group.

[0049] When the rotating platform 3 rotates in the second position, the centrifugal force causes each aluminum foil on the rotating platform 3 to be thrown out of the processing bucket 1 at a high speed on the same horizontal plane. In order for the collection bucket 2 to collect all the aluminum foil thrown out from the rotating platform 3, the top of the collection bucket 2 protrudes from the top of the processing bucket 1. The part of the collection bucket 2 that protrudes from the top of the processing bucket 1 blocks the aluminum foil thrown out of the processing bucket 1, so that the thrown aluminum foil falls smoothly into the collection bucket 2.

[0050] Understandably, when the rotating platform 3 throws the aluminum foil into the collection bucket 2, the water adhering to the rotating platform 3 is also easily thrown into the collection bucket 2, and the aluminum foil is also wet. Figures 1 to 3 To facilitate the draining of aluminum foil inside the processing tank 1, a drain basket 201 is provided inside the collection tank 2. The drain basket 201 is used to drain water from the aluminum foil. Specifically, the aluminum foil is thrown out from the rotating table 3 and enters the drain basket 201. The water on the aluminum foil can be drained through the drain basket 201 to facilitate the subsequent drying of the aluminum foil.

[0051] For example, both the inner wall of the collection bucket 2 and the outer wall of the processing bucket 1 are provided with protruding support blocks 9, and the drain basket 201 abuts against the two support blocks 9. Specifically, the two support blocks 9 surround the processing bucket 1. The drain basket 201 is supported in the collection bucket 2 by the two support blocks 9, so that the drain basket 201 can be detachably placed in the collection bucket 2. When the aluminum foil needs to be removed, the drain basket 201 can be directly removed from the processing bucket 1.

[0052] In another embodiment, refer to Figure 8To improve the automation of the high-voltage pulse separation battery positive electrode current collector device, the device also includes a horizontal moving rod 10 and a feeding mechanism 8. The horizontal moving rod 10 can reciprocate along a set horizontal direction, and the length direction of the horizontal moving rod 10 extends along the set horizontal direction (i.e., the direction indicated by the X arrow in the figure). The horizontal moving rod 10 is spaced above the processing tank 1. The pressure plate 4 is connected to the horizontal moving rod 10 through the second lifting cylinder 7. The feeding mechanism 8 includes a third lifting cylinder 803 and a feeding plate 801. The feeding plate 801 is located between the horizontal moving rod 10 and the processing tank 1. The feeding plate 801 is connected to the horizontal moving rod 10 through the third lifting cylinder 803. The feeding plate 801 and the pressure plate 4 are spaced apart along the length direction of the horizontal moving rod 10. Multiple sets of suction cup assemblies 802 are provided on the side of the feeding plate 801 facing the processing tank 1. Each set of suction cup assemblies 802 can selectively adsorb the positive electrode current collector 100. The feeding mechanism 8 is used to transfer the positive current collector 100 to be processed outside the device of the high voltage pulse separation battery positive current collector to the current collector placement position on the rotary table 3. After the suction cup assembly 802 adsorbs the positive current collector 100 to be processed, the movement of the feeding plate 801 transfers the adsorbed positive current collector 100 to the rotary table 3. The horizontal moving rod 10 moves in a set horizontal direction, which can simultaneously drive the feeding mechanism 8 and the pressure plate 4 to move in the set horizontal direction. In this way, when it is necessary to transfer the positive current collector 100 to be processed to the rotary table 3, the feeding plate 801 is moved to the top of the processing tank 1 by the horizontal moving rod 10. After the third lifting cylinder 803 drives the feeding plate 801 to descend to a set height, the positive current collectors 100 adsorbed on the feeding plate 801 are placed in the corresponding current collector placement positions on the rotary table 3. Then, the third lifting cylinder 803 drives the feeding plate 801, the horizontal moving rod 10 moves the feeding mechanism 8 away from the top of the processing tank 1 and moves the pressure plate 4 to the top of the processing tank 1, so that the pressure plate 4 is ready to press the positive current collectors 100 on the rotary table 3.

[0053] For example, the distance D1 between the pressure plate 4 and the feed plate 801 is set to be greater than the distance D2 between the side wall of the processing tank 1 and the side wall of the collection tank 2. With this design, when the horizontal moving rod 10 moves the feed plate 801 to the side of the collection tank 2 away from the processing tank 1 along the set horizontal direction, the pressure plate 4 is exactly above the processing tank 1. In this way, while the feed plate 801 adsorbs the positive current collector 100 to be processed outside, the pressure plate 4 can press the positive current collector 100 on the rotating table 3, which is beneficial to improving the processing efficiency of the positive current collector 100.
