Description

Technical Field

[0001] The present invention relates to the technical field of power battery recycling, and in particular to a device for sorting diaphragm pole pieces of retired power batteries. Background Art

[0002] The rapid development of the new energy vehicle industry is bound to lead to the rise of the retired power battery recycling industry. Metal elements such as nickel, cobalt, manganese, aluminum, and copper in retired power batteries are high-value components (present in the battery's positive and negative electrodes). Failure to fully recycle and reuse them will result in a waste of resources and environmental pollution. Currently, the primary method for recycling and regenerating battery cells in the market is crushing and screening, which yields high-value components such as copper powder, aluminum powder, and black powder (as exemplified by the Chinese invention patent application number CN201610465314.8). This method has the advantage of being highly versatile and applicable to a wide range of battery cell types. However, its disadvantages are the low purity of the recovered high-value components, high energy consumption, and the clogging of the sieve holes by diaphragm debris during operation, reducing production efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0033] Please refer to Figure 1 and Figure 2 The present invention provides a device for sorting retired power battery diaphragm pole pieces, including a pole group regular cutting mechanism 1, a pole group dispersion mechanism 2, an identification mechanism 3, an eddy current sorting mechanism 4, a magnetic strengthening mechanism 5 and a magnetic separation mechanism 6.

[0034] The electrode group regular cutting mechanism 1 is used to cut the electrode group (the electrode sheets and diaphragms stacked together inside the battery cell are collectively referred to as the electrode group).

[0035] The electrode group dispersing mechanism 2 is used to disperse the cut electrode groups.

[0036] The identification mechanism 3 is used to detect whether the electrode pieces and the diaphragms in the dispersed material are dispersed. If not, the electrode group dispersion mechanism 2 continues to disperse the material until the electrode pieces and the diaphragms in the material are dispersed.

[0037] The eddy current separation mechanism 4 is used to perform eddy current separation on the dispersed material so as to separate the pole pieces and the diaphragm in the material.

[0038] The magnetic strengthening mechanism 5 is used to strengthen the magnetic properties of the positive electrode pieces among the sorted electrode pieces.

[0039] The magnetic separation mechanism 6 is used to separate the positive electrode sheets after magnetic enhancement, so as to separate the positive electrode sheets from the negative electrode sheets.

[0040] During use, the electrode group is first removed from the battery cell, and then the electrode group is placed on the electrode group regular cutting mechanism 1 to be regularly cut into a stack of sheet materials. The stacked materials are then broken up into a single layer without adhesion by the electrode group dispersing mechanism 2. The identification mechanism 3 then detects whether the electrode pieces and diaphragms in the dispersed materials are dispersed. If not, the electrode group dispersing mechanism 2 continues to disperse the materials until the electrode pieces and diaphragms in the materials are dispersed. The dispersed materials enter the eddy current sorting mechanism 4. Since the conductive properties of the electrode pieces and diaphragms are very different, the electrode pieces and diaphragms can be sorted out by the eddy current sorting mechanism 4. The sorted electrode pieces are then processed by the magnetic strengthening mechanism 5. Since the lithium iron phosphate or ternary lithium on the positive electrode pieces are weakly magnetic, their magnetism can be enhanced. Then, the magnetic positive electrode pieces are sorted out by the magnetic separation mechanism 6, thereby achieving the purpose of separating the positive and negative electrode pieces. The device can improve the recovery purity of the positive and negative plates in the battery, thereby facilitating the recovery of high-value components, reducing energy consumption, and preventing diaphragm fragments from clogging the sieve holes, thereby improving production efficiency.

[0041] In order to realize the function of the pole group dispersion mechanism 2, please refer to Figure 3-Figure 6 In a preferred embodiment, the pole group dispersion mechanism 2 includes a Z-type separator 21, a first cyclone separator 22, a first suction fan (not shown), a second cyclone separator 23 and a second suction fan (not shown).

[0042] The Z-type separator 21 has a curved feeding channel. The upper end of the Z-type separator 21 is provided with a feeding port 211 and an upper discharging port 212 connected to the feeding channel. The lower end of the Z-type separator 21 is provided with a lower discharging port 213 connected to the feeding channel.

[0043] The first inlet 221 of the first cyclone separator 22 is communicated with the upper discharge port 212 .

[0044] The first air inlet of the first suction fan is communicated with the first overflow port 222 of the first cyclone separator 22 .

[0045] The second air inlet of the second suction fan is communicated with the second overflow port 232 of the second cyclone separator 23 .

[0046] During use, the regularly cut electrode groups are introduced into the feed port 211 of the Z-type separator 1. When the material is transported in the curved feed channel, the light material (including part of the diaphragm and black powder) in the feed channel is sucked into the first inlet 221 of the first cyclone separator 22 by the negative pressure provided by the first suction fan. In the first cyclone separator 22, the black powder with a lighter specific gravity is discharged from the first overflow port 222, and the diaphragm with a heavier specific gravity is discharged from the first lower discharge port 223. The heavy material in the feed channel (including electrode pieces and diaphragms of regular size) is discharged from the lower discharge port 213 under the action of gravity. The heavy material discharged from the lower discharge port 213 is then introduced into the second inlet 231 of the second cyclone separator 23. In the second cyclone separator 23, under the action of high-speed airflow, the sheet-like electrode groups are broken up into a mixture of electrode pieces and diaphragms, thereby achieving the purpose of dispersing the diaphragms and electrodes in the cut electrode group materials.

[0047] To improve the dispersion effect, please refer to Figure 3-Figure 6 In a preferred embodiment, the flaky material dispersing device further includes a vibrating feeding mechanism 24, which includes a feeding box 241 and a vibrating assembly 242. The feeding box 241 has a feeding cavity. The upper end of the feeding box 241 is provided with a pouring port 2411 communicating with the feeding cavity. The lower end of the feeding box 241 is provided with a feeding port 2412 communicating with the feeding cavity. The feeding port 2412 is connected to the feeding port 211. The vibrating assembly 242 is connected to the feeding box 241 and is used to drive the feeding box 241 to vibrate. During use, the regularly cut electrode group is passed into the feeding port 2412. The vibrating assembly 242 drives the feeding box 241 to vibrate, thereby vibrating and dispersing the flaky electrode group pile and vibrating out the black powder generated by cutting the electrode group and the partially broken diaphragm, thereby facilitating the subsequent dispersion process.

[0048] To specifically implement the function of the vibration component 242, please refer to Figure 6 In a preferred embodiment, the vibration component 242 includes a connecting seat 2421, an elastic member 2422 and an exciter 2423, one end of the elastic member 2422 is fixedly connected to the connecting seat 2421, and the other end of the elastic member 2422 is fixedly connected to the feeding box 241, and the exciter 2423 is connected to the feeding box 241 and is used to drive the feeding box 241 to vibrate.

[0049] To install the connector 2421, please refer to Figure 6 In a preferred embodiment, the flaky material dispersing device further includes a workbench 25 , and the connecting seat 2421 is fixed on the workbench 25 .

[0050] In order to specifically implement the introduction of the heavy materials discharged from the lower discharge port 213 into the second inlet 231 of the second cyclone separator 23, please refer to Figure 3-Figure 5 In a preferred embodiment, the flaky material dispersing device further includes a conveyor belt 26, which is arranged at an angle. The feed end of the conveyor belt 26 is connected to the lower discharge port 213, and the discharge end of the conveyor belt 26 is connected to the second inlet 231 of the second cyclone separator 23. When in use, the heavy material discharged from the lower discharge port 213 falls onto the conveyor belt 26 and is then transported to the second inlet 231 of the second cyclone separator 23 via the conveyor belt 26.

[0051] In order to realize the function of the conveyor belt 26, please refer to Figure 5 In a preferred embodiment, the conveyor belt 26 includes a conveying bracket 261, an active roller 262, a driven roller 263, a conveying belt 264 and a conveying drive member. The active roller 262 and the driven roller 263 are respectively rotatably arranged at the two ends of the conveying bracket 261. The conveying belt 264 is closed, one end of the conveying belt 264 is wound around the active roller 262, and the other end of the conveying belt 264 is wound around the driven roller 263. The conveying drive member is connected to the active roller 262 and is used to drive the active roller 262 to rotate, thereby driving the conveying belt 264 to move.

[0052] In order to realize the function of the conveyor drive, please refer to Figure 5 In a preferred embodiment, the conveying drive member is a conveying drive motor, which is connected to the active roller 262 and is used to drive the active roller 262 to rotate, thereby driving the conveying belt 264 to move.

[0053] To facilitate the collection of sorted materials, please refer to Figure 3 and Figure 5 In a preferred embodiment, the flaky material dispersing device further includes a first receiving barrel 27 , and the first receiving barrel 27 is disposed below the first lower outlet 223 of the first cyclone separator 22 .

[0054] To facilitate the collection of sorted materials, please refer to Figure 3 and Figure 5 In a preferred embodiment, the flaky material dispersing device further includes a second receiving barrel 28 , and the second receiving barrel 28 is disposed below the second lower outlet 233 of the second cyclone separator 23 .

[0055] In order to realize the communication between the upper discharge port 212 and the first inlet 221 of the first cyclone separator 22, please refer to Figure 3In a preferred embodiment, the flaky material dispersing device further includes a connecting pipe 29 , one end of which is connected to the upper discharge port 212 , and the other end of which is connected to the first inlet 221 of the first cyclone separator 22 .

[0056] The following combination Figure 3-Figure 6 The working process of the electrode group dispersion mechanism 2 is described in detail: when in use, the regularly cut electrode group is passed into the feed port 2412, and the vibration component 242 drives the feed box 241 to vibrate, thereby vibrating the flaky electrode group pile and vibrating out the black powder and partially broken diaphragm produced by the cutting of the electrode group. After that, the material enters the feed port 211 of the Z-type sorter 21. When the material is conveyed in the curved conveying channel, the negative pressure provided by the first suction fan sucks the light material (including part of the diaphragm and black powder) in the conveying channel into the first inlet 221 of the first cyclone separator 22, and the material in the first cyclone separator 22 is discharged. The black powder with lighter specific gravity is discharged from the first overflow port 222, and the diaphragm with heavier specific gravity is discharged from the first lower discharge port 223. The heavy materials in the feeding channel (including electrodes and diaphragms of regular size) are discharged from the lower discharge port 213 under the action of gravity. The heavy materials discharged from the lower discharge port 213 fall onto the conveyor belt 26 and are then transported to the second inlet 231 of the second cyclone separator 23 via the conveyor belt 26. In the second cyclone separator 23, under the action of high-speed airflow, the sheet-like electrode group is broken up into a mixture of electrode pieces and diaphragms, thereby achieving the purpose of dispersing the diaphragms and electrodes in the cut electrode group material.

[0057] In order to realize the function of identification mechanism 3, please refer to Figure 6 In a preferred embodiment, the identification mechanism 3 includes a vibration platform and a camera. The vibration platform is used to place the dispersed materials, and the camera is used to take pictures of the materials on the vibration platform. Specifically, the materials before eddy current sorting are monitored by a multi-eye camera to determine whether the electrode diaphragm is completely dispersed. The materials transported on the vibration platform are photographed from different angles by the multi-eye camera, and the image information is collected by the multi-eye camera and transmitted to the control end, and then the image recognition module is used to determine whether the electrode and the diaphragm are bonded together. The vibration platform can cause relative displacement of the dispersed electrode diaphragm materials, thereby improving the accuracy of image recognition.

[0058] The eddy current separation mechanism 4 utilizes a high-speed alternating magnetic field to generate a repulsive force inside the conductor material that is opposite to the magnetic field of the magnetic roller, thereby separating the pole piece from the diaphragm.

[0059] The magnetic strengthening mechanism 5 can reduce the magnetic elements (such as iron, nickel, cobalt, etc.) in lithium iron phosphate or ternary lithium into stronger magnetic materials, or magnetize the active materials in the positive electrode sheet through a high-intensity magnetic field, and then sort out the magnetic positive electrode sheet through the magnetic separation mechanism 6, thereby achieving the purpose of sorting the positive and negative electrode sheets.

[0060] During use, the electrode group is first removed from the battery cell, and then the electrode group is placed on the electrode group regular cutting mechanism 1 to be regularly cut into a stack of sheet materials. The stacked materials are then broken up into a single layer without adhesion by the electrode group dispersing mechanism 2. The identification mechanism 3 then detects whether the electrode pieces and diaphragms in the dispersed materials are dispersed. If not, the electrode group dispersing mechanism 2 continues to disperse the materials until the electrode pieces and diaphragms in the materials are dispersed. The dispersed materials enter the eddy current sorting mechanism 4. Since the conductive properties of the electrode pieces and diaphragms are very different, the electrode pieces and diaphragms can be sorted out by the eddy current sorting mechanism 4. The sorted electrode pieces are then processed by the magnetic strengthening mechanism 5. Since the lithium iron phosphate or ternary lithium on the positive electrode pieces are weakly magnetic, their magnetism can be enhanced. Then, the magnetic positive electrode pieces are sorted out by the magnetic separation mechanism 6, thereby achieving the purpose of separating the positive and negative electrode pieces. The device can improve the recovery purity of the positive and negative plates in the battery, thereby facilitating the recovery of high-value components, reducing energy consumption, and preventing diaphragm fragments from clogging the sieve holes, thereby improving production efficiency.

[0062] (1) The entire sorting process is highly versatile and can be applied to both laminated and wound cells;

[0063] (2) Improved the recycling purity of the positive and negative electrodes of retired power battery cells;

[0066] (5) The entire process does not require the addition of any chemical reagents, has low pollution emissions, low energy consumption, simple maintenance, and is easy to industrialize.

[0067] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
