Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery cell disassembly and recovery, and in particular to a lithium battery cell disassembly and recovery device. Background Art

[0002] With the rapid development of new energy vehicles and renewable energy systems, lithium batteries have been widely used as efficient and environmentally friendly energy storage devices. However, lithium batteries will gradually age and reduce their capacity after a certain number of years of use, and eventually need to be replaced. Waste lithium batteries contain a variety of rare and precious metals (such as cobalt, nickel, manganese, etc.). These metals can significantly reduce dependence on primary mineral resources and reduce production costs through effective recycling. In addition, proper treatment of waste lithium batteries can also reduce pollution to the environment, especially avoiding the leakage of heavy metals and harmful chemicals that cause serious pollution to soil and water sources. Therefore, how to safely and efficiently treat waste lithium batteries is not only related to the recycling of resources, but also involves environmental protection and sustainable social and economic development.

[0003] At present, the main method for disassembling lithium batteries is to manually cut the aluminum casing of the lithium battery with a handheld electric saw, and then take out the battery pack in the casing for further disassembly to recover the rare and precious metals therein; however, this method has a great safety hazard to the operator because the lithium battery contains flammable electrolyte. When the electrolyte leaks and comes into contact with the air, it is easy to form flammable vapor, which may cause fire or explosion when exposed to open flames or high temperatures. In addition, manual cutting of the aluminum casing of the lithium battery is not only time-consuming and labor-intensive, but also inefficient, and cannot meet the needs of large-scale industrial production. In addition, the manual cutting process is prone to electrolyte leakage, increasing the risk of environmental pollution. Summary of the invention

[0034] See also Figure 5 , Figure 6 and Fig. 9 As shown, the absorption mechanism includes a sliding frame 1801 and an absorption pad 1802; sliding frames 1801 are slidably arranged on the middle part of the inner lower side and the inner lower left side of the transparent shell 2, and the two sliding frames 1801 are distributed on the left and right, the sliding frame 1801 on the left is located directly below the filter screen 8, and the sliding frame 1801 on the right is located directly below the sorting frame 13; an absorption pad 1802 is placed in the sliding frame 1801, and the absorption pad 1802 is used to absorb the electrolyte.

[0035] When in use, first use the inflation device to fill the explosion-proof box 14 with nitrogen, and then place the explosion-proof box 14 on the lower right side of the transparent housing 2 (such as Figure 6 Then, the collecting frame 9 is placed in the middle of the top of the bottom plate 1 so that the collecting frame 9 is inside the transparent housing 2 (as shown in FIG. Figure 6 As shown), then the electromagnetic valve 404 is controlled to open, and the nitrogen from the nitrogen tank 401 is input into the air pipe 402 and the transparent housing 2, so that the nitrogen content in the transparent housing 2 gradually increases. Since nitrogen is slightly heavier than air, the nitrogen will sink inside the transparent housing 2 and push the lighter air to be discharged from the nitrogen analyzer 403. During this period, the nitrogen analyzer 403 is used to continuously detect the nitrogen concentration in the exhaust gas. When the nitrogen inside the transparent housing 2 reaches a certain amount, the nitrogen in the transparent housing 2 will also be gradually discharged from the nitrogen analyzer 403. When the operator observes that the nitrogen concentration on the nitrogen analyzer 403 reaches a predetermined value, the electromagnetic valve 404 is controlled to close, and the nitrogen from the nitrogen tank 401 is stopped from being input into the air pipe 402 and the transparent housing 2. In this way, the transparent housing 2 can be filled with nitrogen;

[0036] Then, the cover plate 303 is lifted up so that the cover plate 303 no longer blocks the top of the discharge channel 302 (at this time, the abutment plate 306 is used to block the outside air and the nitrogen in the transparent shell 2 to prevent nitrogen leakage), and then the drive motor 304 is controlled to drive the first screw rod 305 to rotate, so that the first screw rod 305 drives the abutment plate 306 to move upward in the discharge channel 302 until the abutment plate 306 moves to the uppermost end of the first screw rod 305, and then the used lithium batteries are stacked on the top of the abutment plate 306, and then the drive motor 304 is controlled to drive the first screw rod 305 to reverse, so that the first screw rod 305 drives the abutment plate 306 to move downward and reset, so that the abutment plate 306 brings the stacked used lithium batteries into the discharge channel 302 for storage, and then the cover plate 303 is placed The cover plate 303 is then controlled to return to its original position, so that the cover plate 303 covers the top of the discharge channel 302 again, and then the driving motor 304 is controlled to drive the first screw rod 305 to reverse, so that the abutment plate 306 drives the stacked waste lithium batteries to move downward, until the waste lithium batteries at the bottom are flush with the L-shaped plate 308 (at this time, the cover plate 303 is used to block the outside air and the nitrogen in the transparent shell 2 to prevent nitrogen leakage), and then the second electric push rod 307 is controlled to drive the L-shaped plate 308 to move right, so that the L-shaped plate 308 pushes the waste lithium batteries at the bottom to the right onto the clamping conveyor 5 in the transparent shell 2, and the L-shaped plate 308 blocks the remaining waste lithium batteries in the discharge channel 302, and then the second electric push rod 307 is controlled to drive the L-shaped plate 308 to move left to return to the original position, so that the cover plate 303 covers the top of the discharge channel 302 again, and then the second electric push rod 307 is controlled to drive the L-shaped plate 308 to move left to return to the original position, so that the cover plate 303 covers the top of the discharge channel 302 again, and then the second electric push rod 307 is controlled to drive the L-shaped plate 308 to move left to return to the original position, so that the L-shaped plate 308 The L-shaped plate 308 is positioned so that the remaining waste lithium batteries in the discharge channel 302 no longer block the waste lithium batteries, so that the remaining waste lithium batteries in the discharge channel 302 fall down onto the abutment plate 306, and then the waste lithium batteries in the transparent shell 2 are transported to the right by the clamping conveyor 5, and the ceramic saw blade 7 is driven to rotate by the servo motor 6. When the waste lithium batteries come into contact with the ceramic saw blade 7, the ceramic saw blade 7 will cut the front and back sides of the shell of the waste lithium batteries until the front and back sides of the shell are cut off. The cut shell will fall down onto the filter screen 8, and then roll from the filter screen 8 to the collection frame 9 for collection. At the same time, when the shell of the waste lithium battery is cut, the leaked electrolyte will fall down onto the filter screen 8, and then pass through the filter screen 8. Continue to fall down into the sliding frame 1801 on the left, and then the electrolyte is absorbed by the absorption pad 1802 in the sliding frame 1801 on the left. After the front and rear sides of the shell of the used lithium battery are cut, the clamping conveyor 5 will continue to convey the used lithium battery to the right. When the used lithium battery passes through the temperature sensor 1701, the temperature sensor 1701 will detect the temperature of the used lithium battery. If the temperature sensor 1701 detects that the temperature of the used lithium battery is normal, the temperature sensor 1701 will send a normal signal. If the temperature sensor 1701 detects that the temperature of the used lithium battery is abnormal, the temperature sensor 1701 will send an abnormal signal, and then the control box 1702 receives the normal or abnormal signal sent by the temperature sensor 1701.If the signal received by the control box 1702 is a normal signal, the control box 1702 will control the clamping conveyor 5 to convey the used lithium batteries to the right until they are aligned with the push block 11 on the rear side, and then the control box 1702 will control the first electric push rod 10 on the rear side to drive the push block 11 to move forward, so that the push block 11 pushes the battery pack in the shell of the used lithium battery forward, so that the battery pack falls into the storage space on the left side of the sorting box 13 for collection, and then the control box 1702 will control the first electric push rod 10 on the rear side to drive the push block 11 to move backward and reset, and then the control box 1702 will control the clamping conveyor 5 to convey the used lithium batteries to the right until they are aligned with the push block 11 on the front side, and then the control box 1702 will control the first electric push rod 10 on the front side to drive the push block 11 to move backward. The control box 1702 will then control the first electric push rod 10 on the front side to drive the push block 11 to move forward and reset. In this way, the waste lithium batteries on the clamping conveyor 5 can be automatically disassembled. When the battery pack and the waste lithium battery shells fall into the sorting frame 13, the electrolyte leaked from the battery pack and the waste lithium battery shells will fall down through the through holes of the sorting frame 13 into the sliding frame 1801 on the right, and then the electrolyte will be absorbed by the absorption pad 1802 in the sliding frame 1801 on the right. If the signal received by the control box 1702 is an abnormal signal, the control box 1702 will control the clamping conveyor 5 to push the waste lithium The battery is conveyed to the right all the time until the used lithium battery is separated from the clamping conveyor 5 and falls downward. When the used lithium battery falls downward and contacts the explosion-proof plate 15, the used lithium battery will use its own gravity to squeeze the explosion-proof plate 15 to rotate and open, and the shrapnel 16 will be deformed, causing the used lithium battery to fall into the explosion-proof box 14. When the used lithium battery is separated from the explosion-proof plate 15, the shrapnel 16 returns to its original state, and the shrapnel 16 drives the explosion-proof plate 15 to reverse and reset, so that the explosion-proof plate 15 shields the used lithium battery in the explosion-proof box 14. By sending the used lithium battery with abnormal detection into the explosion-proof box 14, it is possible to prevent the used lithium battery with abnormal detection from exploding or burning and affecting the disassembly and recovery device. Thereafter, the above operation can be repeated to repeatedly disassemble the used lithium battery, and And because the disassembly of the waste lithium batteries is carried out in the nitrogen environment in the transparent shell 2, it is possible to prevent the electrolyte in the waste lithium batteries from volatilizing and burning. At the same time, the inert characteristics of nitrogen can inhibit chemical reactions, reduce the generation of harmful gases, and improve the safety of disassembly of the waste lithium batteries. After that, when all the waste lithium batteries are disassembled, the collection frame 9 is taken out, and the waste lithium battery shells in the collection frame 9 are processed, and then the explosion-proof box 14 is taken out, and the waste lithium batteries in the explosion-proof box 14 that are in an abnormal state are processed, and then the baffle 201 is pulled upward, and then the sorting frame 13 is pulled forward. During this period, the rotating column 12 can be used to facilitate the forward movement of the sorting frame 13, and then the waste lithium battery shells and battery packs in the sorting frame 13 are processed separately.After the waste lithium battery shells and battery packs in the sorting frame 13 are processed, the sorting frame 13 is pushed back to its original position, and then the baffle 201 is pulled down to reset, and then the sliding frame 1801 is pulled forward. Since the electrolyte is absorbed in the absorption pad 1802, the contact area between the electrolyte and the air can be reduced, thereby reducing the volatilization of the electrolyte and the release of harmful gases. After that, the absorption pad 1802 in the sliding frame 1801 is replaced, and then the sliding frame 1801 is pushed back to its original position.

[0038] By setting the magnetic stripe 19 and the magnetic block 20, when the baffle 201 moves upward, the baffle 201 will drive the magnetic stripe 19 to move upward, so that the magnetic stripe 19 contacts the magnetic block 20, so that the magnetic stripe 19 is adsorbed on the magnetic block 20 to fix the baffle 201, thereby replacing the manual fixation of the baffle 201, so as to facilitate the operator to take out and push back the sorting frame 13; when the baffle 201 moves downward to reset, the baffle 201 will drive the magnetic stripe 19 to move downward to reset, so that the magnetic stripe 19 is separated from the magnetic block 20.

[0039] See also Fig.10 and Fig.11 As shown, a shielding mechanism is also included, which includes a multi-section telescopic rod 21, a shielding plate 23 and a spring 22; the number of the multi-section telescopic rods 21 is four, and the four multi-section telescopic rods 21 are distributed left and right, the rear ends of the two multi-section telescopic rods 21 on the left side are connected to the lower left part of the rear side of the transparent shell 2, and the left ends of the two multi-section telescopic rods 21 on the right side are connected to the lower right part of the transparent shell 2; a shielding plate 23 is connected between the front ends of the two multi-section telescopic rods 21 on the left side, and a shielding plate 23 is also connected between the right ends of the two multi-section telescopic rods 21 on the right side, and the shielding plate 23 is used to shield the nitrogen inside the transparent shell 2; two springs 22 are connected between the shielding plate 23 and the transparent shell 2.

[0040] When the explosion-proof box 14 is placed on the lower right side of the transparent housing 2 (such as Figure 6 As shown in the figure, the explosion-proof box 14 will squeeze the shield plate 23 on the right side to move to the left, so that the multi-section telescopic long rod 21 on the right side will shrink and the spring 22 on the right side will be compressed. After that, when the explosion-proof box 14 is placed, the explosion-proof box 14 will continue to squeeze the shield plate 23 on the right side by using the friction between the explosion-proof box 14 and the transparent shell 2 (the friction between the explosion-proof box 14 and the transparent shell 2 is greater than the elastic force of the spring 22 on the right side). When the collection frame 9 is placed in the middle of the top of the bottom plate 1 (as shown in the figure), the explosion-proof box 14 will squeeze the shield plate 23 on the right side by using the friction between the explosion-proof box 14 and the transparent shell 2. Figure 6As shown in the figure, the collection frame 9 will squeeze the shield plate 23 on the left to move backwards, so that the multi-section telescopic long rod 21 on the left will shrink and the spring 22 on the left will be compressed. After that, when the collection frame 9 is placed, the collection frame 9 will use the friction between itself and the bottom plate 1 to continue squeezing the shield plate 23 on the left (the friction between the collection frame 9 and the bottom plate 1 is greater than the elastic force of the left spring 22); when the explosion-proof box 14 and the collection frame 9 are taken out, the explosion-proof box 14 will be separated from the shield plate 23 on the right. At this time, the spring 22 on the right will return to its original state, and the spring 22 on the right will drive the shield plate 23 to move right to return to its original state. The multi-section telescopic long rod 21 on the right is reset, and the shield 23 on the right blocks the right lower side of the transparent shell 2 to prevent a large amount of nitrogen in the transparent shell 2 from leaking out; the collecting frame 9 is separated from the shield 23 on the left, and the spring 22 on the left is restored to its original state, and the spring 22 on the left drives the shield 23 to move forward and reset, so that the multi-section telescopic long rod 21 on the left is reset, and the shield 23 on the left blocks the front lower side of the transparent shell 2 to prevent a large amount of nitrogen in the transparent shell 2 from leaking out, and at the same time protect the nitrogen in the transparent shell 2 to facilitate the next use, thereby saving resources.

[0041] See also Fig.12 As shown, it also includes a closing mechanism, which includes a guide frame 24, a reduction motor 25, a second screw rod 26 and a closing plate 27; the guide frame 24 is installed on the right rear side of the transparent shell 2; the reduction motor 25 is connected to the rear side of the guide frame 24; the second screw rod 26 is connected to the output shaft of the reduction motor 25, and a closing plate 27 is slidably connected to the guide frame 24, the closing plate 27 is threadedly connected to the second screw rod 26, the front side of the closing plate 27 is slidably connected to the rear side of the transparent shell 2, and the closing plate 27 is used to close the interior of the transparent shell 2.

[0042] When it is necessary to pull the baffle 201 upward, the reduction motor 25 can be controlled to drive the second screw rod 26 to rotate, so that the second screw rod 26 drives the closing plate 27 to extend forward into the transparent shell 2, so that the closing plate 27 closes the interior of the transparent shell 2, and then the baffle 201 can be pulled upward. After the baffle 201 moves upward, the interior of the transparent shell 2 is closed by the closing plate 27, which can block the nitrogen inside the transparent shell 2 to prevent a large amount of nitrogen in the transparent shell 2 from leaking out, and at the same time protect the nitrogen in the transparent shell 2 to facilitate the next use, thereby saving resources; when the baffle 201 is pulled downward, the reduction motor 25 is controlled to drive the second screw rod 26 to reverse and reset, so that the second screw rod 26 drives the closing plate 27 to move backward and reset.

[0043] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
