Description

Technical Field

[0001] The present invention relates to the field of battery recycling, and in particular to a material recycling device and a recycling method for waste power lithium batteries. Background Art

[0002] With the rapid development of the new energy vehicle industry, the recycling technology of waste lithium batteries has become a hot topic of research. At present, the recycling and processing technologies of waste lithium batteries mainly include low-temperature pyrolysis technology, high-temperature pyrolysis technology, gradient pyrolysis technology, hydrometallurgy technology, pyrometallurgy technology, etc. These technologies have their own advantages and disadvantages and are suitable for different recycling scenarios and requirements. The recycling equipment can disassemble and recycle the battery in an all-round way, including the battery shell, electrode materials, electrolyte and other parts. Through refined disassembly technology, these equipment can maximize the recovery of valuable materials in the battery and reduce the impact on the environment. Various materials in the battery are recycled and regenerated into new materials.

[0003] Chinese patent application CN114142117A discloses a lithium battery recycling device, in which an inner hole is provided inside the main body of the device, and a cutting blade welded to a tool holder is installed at the bottom, which is used to accurately cut the metal structure at the bottom of the battery. A rotating motor is fixed to the motor bracket, and the rotating shaft at its output end passes through the tool holder. Scrapers are welded on both sides to help discharge the cut materials. The cutting blade is provided with a storage hole for the scraper to pass through. The combined design of the base frame and the spring makes the cutting process more convenient, and the cooperation between the cover body and the rotating plate enhances the cutting effect inside the battery. At the same time, the rotating motor drives the scraper to move, effectively realizing the discharge function and improving the efficiency of the entire recycling process.

[0004] CN112652833A discloses a lithium battery recycling device, which includes a workbench with supporting feet, on which a distribution table, a driving device and a battery are fixed, and a conveying device, a lifting device, a pushing device and a cutting device are arranged on the distribution table. The conveying device includes a placement trough, a lifting bin, a conveying trough and a plurality of rotatably connected conveying rollers and a split belt. The lifting device and the pushing device work together to ensure the automatic and orderly feeding of waste lithium batteries and the removal of plastic skins. This design reduces manual operation, reduces the risk of workers being exposed to harmful chemicals, and improves the safety and efficiency of the recycling process.

[0005] The above patents and prior art also have the following defects:

[0006] Existing lithium battery recycling is done by crushing the batteries and then recycling them. Since the battery assembly contains multiple components, such as the positive electrode of the battery contains cobalt, manganese, nickel, lithium, etc.; the negative electrode contains graphite, silicon-based materials, etc., and there is also a polymer plastic separator in the battery, these substances will be mixed together after crushing and need to be separated later. Some substances have inconsistent forms after crushing, such as the cobalt, manganese, nickel and lithium in the positive electrode form powder when crushed, and the aluminum metal of the outer shell and the aluminum and copper metal of the positive and negative electrode collectors form metal fragments when crushed. During separation, the powdered material is easy to adhere to the fragments, resulting in incomplete separation, which requires cleaning, resulting in waste of recycled materials and reduced recovery rate.

[0023] In summary, the technical effects and advantages of the present invention are as follows:

[0024] 1. In the present invention, the feeding assembly can intermittently move the lithium battery to the clamping unit position to drive the lithium battery feeding, and the feeding position is accurate, which is convenient for clamping and processing the lithium battery. The two clamping units clamp the ends of the lithium battery respectively, and the cutting blade cuts the middle of the lithium battery to separate the positive and negative electrodes of the lithium battery, so as to facilitate the recycling of the positive and negative electrodes of the lithium battery respectively.

[0025] 2.

The feeding frame 33 is rotatably connected with a support rod corresponding to the position of the rotating wheel 32. The support rod is rotatably connected to the side wall of the corresponding rotating wheel 32 close to the outer ring. The plurality of feeding blocks 34 are fixedly mounted on the feeding frame 33.

[0048] The cutting assembly 4 includes a plurality of sun cutting wheels 41 and a plurality of planetary cutting wheels 42, which are arranged alternately with each other, and the plurality of sun cutting wheels 41 and the plurality of planetary cutting wheels 42 are both capable of rotating, and the plurality of planetary cutting wheels 42 move around the sun cutting wheel 41 during the rotation process.

[0049] After the lithium battery is discharged, it is horizontally transferred to the feed trough at the end of the support frame 31, and the rotating wheel 32 rotates, and the rotating wheel 32 drives the support rod to move, and the support rod drives the feed frame 33 to move. Since the support rod is rotatably connected to the position close to the outer ring of the rotating wheel 32, the support rod drives the feed frame 33 to move horizontally periodically and move vertically while moving horizontally, and the feed frame 33 drives the feed block 34 to move. The feed block 34 first lifts the lithium battery in the feed trough and drives the lithium battery to move, and moves the lithium battery to the next feed trough. Each time the rotating wheel 32 rotates, the lithium battery in the feed trough is moved to the next feed trough, thereby continuously moving the lithium battery to the feed trough below the clamping unit 22, and the lithium battery is in a horizontal state, the clamping and cutting assembly 2 moves downward, and the two groups of clamping units 22 move to both ends of the lithium battery.

After the lithium batteries in the feed trough at the end of the support frame 31 are moved to the next feed trough, the lithium batteries on the feed inclined plate 35 enter the feed trough at the end of the support frame 31 under the action of gravity, thereby moving the lithium batteries to the feed trough located below the clamping unit 22, and the feeding position is more accurate, which is convenient for clamping the clamping unit 22.

[0064] After the cutting assembly 4 has finished cutting the material in the lithium battery, the lithium battery clamped on the clamping unit 22 is cut into a lithium battery shell, the clamping and cutting assembly 2 rises, driving the corresponding lithium battery shell to rise, then the moving unit 23 drives the cutting shell 212 to rise, the cutting shell 212 drives the pushing block 215 to rise, the clockwork spring 225 drives the rotating frame 223 to reset, the rotating frame 223 drives the lithium battery shell to flip, so that the lithium battery shell flips to a horizontal state, then the clamping and cutting assembly 2 moves downward, moves the lithium battery shell to the feeding slot below the clamping unit 22, and the lithium battery shell is supported by the corresponding feeding block 34, and then the lithium battery shell is fed into the feeding slot. When the material block 34 moves in the next cycle, it drives the lithium battery shell to move to the next feed trough. When the feed block 34 moves away from the lithium battery shell, since the lithium battery shell is cut into two parts, the lithium battery shell cannot be stably placed in the feed trough on the support frame 31, and the lithium battery shell is cut from the middle, and the support frame 31 is at the end of the lithium battery shell. When the lithium battery shell is moved to the next feed trough, the lithium battery shell tilts and falls into the discharge barrel 37 between the two support frames 31 under the action of gravity, and the lithium battery shell is unloaded. The lithium battery shell can be lowered separately, which is convenient for subsequent processing and recycling of the lithium battery shell.

[0065] Example 7, further, referring to Figure 1-Figure 13 The two support frames 31 are fixedly mounted on the frame 1, and the two support frames 31 are provided with cutting conveyor belts 5. The frame 1 is provided with a shell conveyor belt 6. The two cutting conveyor belts 5 are respectively located under the corresponding clamping units 22, and the two cutting assemblies 4 are respectively located under the corresponding clamping units 22. The cutting conveyor belt 5 is located under the discharge barrel 37.

[0066] After the lithium battery is cut into two parts, the positive electrode and the negative electrode, the two parts are cut by two cutting assemblies 4 to cut the internal materials, and the cut materials fall onto two cutting conveyor belts 5 respectively, and are unloaded through the two cutting conveyor belts 5, and the lithium battery shell is unloaded in cooperation with the discharge cylinder 37, and the lithium battery shell falls to the shell conveyor belt 6 for unloading.

[0067] Not only can the positive electrode material, negative electrode material and shell of the lithium battery be recycled separately, but there will be no difficulty in separation due to mixing of materials. When the materials are recycled separately, it is not easy to be mixed with other materials, thereby improving the recycling efficiency of lithium battery materials. In addition, the lithium battery can be fed, clamped, cut, and the positive and negative electrodes and shells can be unloaded separately. The process sequence is smoother, manual intervention is less, and the recycling efficiency is high.

The flip motor 44 is fixedly mounted on the corresponding support frame 31, the fixed plate 45 is rotatably mounted on the support frame 31, and the output end of the flip motor 44 is fixedly mounted on the fixed plate 45. The transmission unit 49 includes a sun shaft, a planet carrier 491, a planetary shaft, a sun gear 492, a planetary gear 493 and a gear ring 494. The planet carrier 491 is rotatably mounted on the fixed plate 45, the cutting housing 43 is fixedly mounted on the fixed plate 45, the sun shaft is rotatably connected to the planet carrier 491 and the cutting housing 43, the planetary shaft is rotatably connected to the planet carrier 491, and a plurality of sun cutting The cutting wheel 41 is fixedly mounted on the sun shaft, a plurality of planetary cutting wheels 42 are fixedly mounted on the planetary shaft, cutting teeth are fixedly mounted on both the sun cutting wheel 41 and the planetary cutting wheel 42, the sun cutting plate 47 is fixedly mounted on the top of the sun shaft, the planetary cutting plate 48 is fixedly mounted on the top of the planetary shaft, a plurality of cutting protrusions are fixedly mounted on the top of both the sun cutting plate 47 and the planetary cutting plate 48, the sun gear 492 is fixedly mounted on the sun shaft, the planetary gear 493 is fixedly mounted on the planetary shaft, the ring gear 494 is fixedly mounted on the cutting housing 43, the planetary gear 493 is meshed with the sun gear 492 and the ring gear 494, the cutting motor 46 is fixedly mounted on the cutting housing 43, and the output end of the cutting motor 46 is fixedly mounted on the sun shaft.

[0069] The cutting motor 46 drives the sun shaft to rotate, and the sun shaft drives the sun gear 492 to rotate. The planetary gear 493 rotates under the drive of the sun gear 492 and the limit of the ring gear 494, and the planetary gear 493 moves around the sun gear 492. The planetary carrier 491 supports the planetary shaft, and the sun shaft drives the sun cutting plate 47 and the sun cutting wheel 41 to rotate. The planetary shaft drives the planetary cutting plate 48 and the planetary cutting wheel 42 to rotate. The planetary cutting plate 48 and the sun cutting plate 47 cut the material inside the lithium battery and drop it. During the falling process of the material inside the lithium battery, the sun cutting wheel 41 and the planetary cutting wheel 42 bite each other to bite and tear the internal material into pieces, thereby improving the crushing effect of the material. , and the crushing effect on the plastic diaphragm inside the battery is better. The crushed material has a better effect in the subsequent processing process. The cut material falls to the corresponding cutting conveyor belt 5 for unloading. After the lithium battery cutting is completed, the flip motor 44 drives the fixed plate 45 to rotate, and the fixed plate 45 drives the sun shaft, the planetary shaft, the sun cutting plate 47, the planetary cutting plate 48, the planetary cutting wheel 42 and the sun cutting wheel 41 to rotate to a horizontal state, so that the debris on the fixed plate 45, the sun cutting plate 47, the planetary cutting plate 48, the planetary cutting wheel 42 and the sun cutting wheel 41 falls to the cutting conveyor belt 5 for unloading, avoiding dead corners, having a better unloading effect on the material, and reducing the difficulty of cleaning.
