Description

Technical Field

[0001] The invention relates to the field of waste battery recycling, and in particular to a waste battery elastic shearing device and process. Background Art

[0002] Lithium-ion batteries are a type of secondary battery that relies mainly on the movement of lithium ions between the positive and negative electrodes to work. In order to reduce resource loss, lithium-ion batteries are generally recycled and reused after they are damaged, and the lithium-ion batteries are decomposed into raw materials for recycling and reuse. Among them, the recovery of lithium-ion battery electrolyte, since existing lithium-ion batteries are generally composed of multiple battery cells, the recovery of electrolyte in the battery cells generally includes the following steps: 1. Battery discharge and disassembly, 2. Battery cell crushing, 3. Electrolyte collection and treatment, 4. Lithium salt recovery, 5. Waste treatment; and then it is necessary to first discharge the waste lithium battery and disassemble it by elastic shearing, then crush the battery cell, and then collect the electrolyte, and the electrolyte collection requires the use of professional recycling equipment.

[0003] The patent with publication number CN118299712A discloses a lithium-ion battery electrolyte recovery device, which includes a crystallization device for evaporating and crystallizing a lithium salt solution, a fixed cylinder and a feed pipe for feeding the electrolyte; and also includes: a collecting mechanism, which is arranged at the bottom end of the fixed cylinder, and the top opening of the fixed cylinder is internally threaded with a sealing cover, the top side of the sealing cover is provided with an expanding tube, and the bottom end of the expanding tube is inserted into the sealing cover and fixedly connected to the sealing cover, and the feed pipe penetrates the tube wall of the expanding tube and is fixedly connected to the expanding tube. The top end of the expanded tube is connected to a soft tube, and a sealing mechanism is provided in the sealing cap; a heating mechanism is provided between the crystallization device and the fixed cylinder, and a filtering mechanism is provided in the fixed cylinder. This device can gasify and separate the organic solution in the electrolyte from the electrolyte. At the same time, when the electrolyte is heated, part of the high-temperature water vapor dissolves in the electrolyte to dilute the electrolyte, and the sealing mechanism intercepts the water droplets entrained in the water vapor, and makes the water droplets fall on the solid debris, and the residual electrolyte on the solid debris is flushed into the diluted electrolyte.

[0004] However, the above prior art has the following technical defects:

[0005] 1. The above-mentioned prior art can only remove fixed debris from the electrolyte after diluting most of the electrolyte attached to the surface of the solid debris in the electrolyte, and uses the condensed water droplets of high-temperature water vapor to drop on the fixed debris to flush the small amount of electrolyte attached to the surface of the fixed debris. However, it takes time for the high-temperature water vapor to condense into water droplets, thereby increasing the time consumed by the entire recycling work and reducing the recycling efficiency of the device. At the same time, the size of the baffle used by the device to assist the condensation of water droplets is smaller than the size of the filter cartridge, and thus all the solid debris in the filter cartridge cannot be flushed.

[0006] Second: During the subsequent drying process, some tiny fixed debris may adhere to the inner wall of the filter cartridge and cannot be poured out of the filter cartridge. The staff needs to clean it manually, which makes the operation very cumbersome and requires the use of professional cleaning tools, which is very troublesome.

[0007] Therefore, based on the existing lithium-ion battery electrolyte recovery device, in order to overcome the above-mentioned technical defects, there is still room for improvement. Summary of the invention

[0027] In summary, the present application includes at least one of the following beneficial technical effects of the device and process for elastically shearing waste batteries:

[0028] 1. The present invention is provided with a flushing mechanism and a collecting mechanism. During the process of heating and diluting the electrolyte, the collecting mechanism can collect part of the water in the high-temperature water vapor that emerges. After a large amount of electrolyte attached to the surface of solid debris is removed, after solid-liquid separation, the flushing mechanism can cooperate with the water in the collecting mechanism to form a moving water curtain above the filter cartridge to flush the solid debris. Since this flushing method is in the form of a water curtain flushing, all solid debris in the filter cartridge can be flushed without omission. At the same time, the water curtain falls from a high place and is accelerated by gravity to improve the flushing effect and avoid incomplete cleaning of the electrolyte. At the same time, this flushing obviously takes less time, thereby shortening the time spent on the entire recovery work and accelerating the recovery efficiency.

[0029] 2. The scraper mechanism and transmission mechanism are set up in the present invention. The shortening of the electric push rod will allow the scraper in the scraper mechanism to extend into the filter cartridge. When the staff drains water from the collection box, the transmission mechanism can move the piston plate during the draining process to move the fourth rack, so that the scraper rotates to scrape the inner wall of the filter cartridge to avoid the situation where adhered solid debris cannot be poured out of the filter cartridge. Manual cleaning is not required for the staff, thereby reducing the labor of the staff. At the same time, the rotational power of the scraper comes from the piston plate that moves when the collection box is drained, and is transmitted through the transmission mechanism. There is no need to use additional electrical equipment such as motors, which makes the manufacturing cost of this device low. At the same time, the transmission mechanism has a simple structure and a long service life, and the linkage between the scraper mechanism and the collection mechanism is realized, thereby enhancing the integrity of the device.

[0068] On the other hand, the present application also discloses a process for elastic shearing of waste batteries, the process steps of which are as follows:

[0069] S1. Electrolyte dilution: The electrolyte mixed with solid impurities in the disassembled waste battery after elastic shearing is placed into the filter cartridge 308 in the recycling box 1, and high-temperature steam is injected into the recycling box 1 through the steam pipe 13. Specifically, the upper cover 507 is removed, and the electrode liquid mixed with solid impurities is sent into the filter cartridge 308 through the upper pipe 504 and the lower pipe 505, and then the upper cover 507 is re-covered. Due to the obstruction of the filter cartridge 308, the solid impurities will not overflow, and the recycling box 1 The electrolyte level in the recovery box 1 is not higher than the port of the filter cartridge 308. High-temperature water vapor is injected into the electrolyte in the recovery box 1 through the steam pipe 13. The high-temperature water vapor and the electrolyte undergo heat exchange to heat the electrolyte. At the same time, part of the gas condenses into water and dissolves in the electrolyte to dilute the electrolyte. After the electrolyte is diluted, the electrolyte adhering to the solid debris gradually dissolves in the diluted electrolyte. At the same time, the electrolyte is at high temperature for a long time, and the organic solvent in the electrolyte vaporizes and emerges from the electrolyte along with the high-temperature water vapor.

[0070] S2. Water vapor collection; high-temperature water vapor emerges from the electrolyte and is transported to the collecting mechanism 4 to allow water droplets in the airflow to gather in the collecting box 401. Specifically, the high-temperature water vapor emerging from the electrolyte enters the collecting box 401 through the lower tube 505, the upper tube 504 and the input tube 412. When the rising high-temperature water vapor passes through the gap of the inclined plate 411, the water droplets in the airflow adhere to the inclined plate 411, aggregate into large water droplets, and fall down to gather in the collecting box 401. The remaining airflow is discharged and collected from the output tube 410. When the water in the collecting box 401 continues to gather, the weight increases, pressing down the piston plate 402 while compressing the first spring 405.

[0071] S3, solid-liquid separation: the electric push rod 301 shortens and drives the filter cartridge 308 to rise so that solid debris can be removed from the electrolyte. Specifically, the electric push rod 301 contracts and drives the filter cartridge 308 to rise through the fixed seat 302. The rising filter cartridge 308 drives the solid debris therein to rise until the solid debris is removed from the electrolyte. At the same time, the rising fixed seat 302 also drives the U-shaped frame 17 and the second rack 508 to rise through the connecting rod 16.

[0072] S4, solid flushing: the electric push rod 301 shortens and drives the flushing mechanism 2 to operate, and uses the collected water to flush the solid debris in the filter cartridge 308, and uses the water to bring a small amount of electrolyte attached to the surface of the solid debris into the electrolyte in the recovery box 1. Specifically, the electric push rod 301 contracts and drives the U-shaped frame 17 to rise, and at the same time, it also drives the first rack 208 to rise through the extension rod 213, the second magnet 212 and the iron plate 209. The rising first rack 208 drives the second rack 208 to move upward. The first gear 201 rotates, and the rotating first gear 201 drives the slide rail 202 to rotate around the same center of the first gear 201, so that the end of the slide rail 202 close to the C-shaped slide seat 203 rises, and the other end falls, until the first magnetic block 211 contacts the iron plate 209, and the descending end of the slide rail 202 contacts the same side limit block 214, and because the C-shaped slide seat 203 is at a high position, the C-shaped slide seat 203 slides on the slide rail 202, and the moving C-shaped slide seat 203 3 drives the water distribution tank 204 and the water outlet pipe 205 to move. When the L-shaped baffle 206 is separated from the water outlet pipe 205, the blockage of the lower end of all the water outlet pipes 205 is released, and the water in the collection box 401 enters the water distribution tank 204 through the telescopic hose 207, and finally flows out from each water distribution tank 204, forming a water curtain under the water distribution tank 204. At the same time, the moving water distribution tank 204 pulls all the telescopic hoses 207 to extend, and the moving water distribution tank 204 also drives The water curtain moves, allowing the water curtain to pass over the filter cartridge 308. The water curtain passing through the filter cartridge 308 can flush all solid debris in the filter cartridge 308, and use water to bring a small amount of electrolyte attached to the surface of the solid debris into the electrolyte in the recovery box 1 until the U-shaped slide seat 203 slides to the other end of the slide rail 202, and the solid debris is blocked. The water in the collection box 401 continuously enters the water distribution tank 204 until the water level in the collection box 401 is lower than the connection point of the telescopic hose 207.

[0073] S5, circle scraping filter cartridge: use the scraper 506 in the scraper mechanism 5 to cooperate with the transmission mechanism 6 to scrape off the small solid debris adhering to the inner wall of the filter cartridge 308 during the drainage process of the collection box 401. Specifically, in the water vapor collection process of S2, the descending piston plate 402 drives the connecting plate 609 to descend through the water outlet pipe 406, and the descending connecting plate 609 pulls the slider 602 to move through the pull rope 608. The moving slider 602 compresses the second spring 603 and drives the fourth rack 606 to move through the extension block 605. After the solid debris in the filter cartridge 308 is flushed, the high-temperature water vapor that continuously passes through the gaps between the solid debris in the filter cartridge 308 passes through the gaps between the solid debris in the filter cartridge 308, heats the solid debris, and most of the water on its surface evaporates. At the same time, the removal of the organic solvent in the electrolyte is completed, and the electric push rod 301 continues to shorten and drives the filter cartridge 308 to continue to rise through the fixed seat 302. At the same time, it drives the U-shaped frame 17 to rise through the connecting rod 16. The rising U-shaped frame 17 allows the second rack 508 to be connected with the first rack 508. The second gear 509 meshes, and then the rising second gear 509 drives the third rack 510 to descend, driving the lower tube 505 and the scraper 506 to descend, allowing the scraper 506 to extend into the filter cartridge 308, and the blade contacts the inner wall of the filter cartridge 308. At the same time, the descending lower tube 505 drives the third gear 607 to descend and mesh with the fourth rack 606. The staff opens the valve 407 to let the water in the collection box 401 be discharged from the outlet pipe 406. When the water is discharged, the two compressed first springs 405 The rebound drives the piston plate 402 to rise, and the contact pulls the slider 602. The compressed second spring 603 rebounds and drives the slider 602 to move, and then drives the fourth rack 606 to move. The moving fourth rack 606 drives the lower tube 505 to rotate through the third gear 607. The rotating lower tube 505 drives the fourth rack 606 to rotate and scrape the inner wall of the filter cartridge 308, so as to scrape off the tiny solid debris adhering to the inner wall of the filter cartridge 308, so as to prevent it from being poured out of the filter cartridge 308.

[0074] At the same time, the rising U-shaped frame 17 will also drive the second magnet 212 to continue to rise through the extension rod 213 until the iron plate 209 and the two first magnetic blocks 211 are released and magnetically attracted, and the extending rod 213 that continues to rise drives the second magnet 212 to rise and disconnect from the iron plate 209.

[0075] S6, discharge: discharge the electrolyte in the recovery box 1 and pour out the dried solid debris in the filter cartridge 308. Specifically, open the solenoid valve 19, send the electrolyte that has removed the solid debris and organic solvent from the lower port of the funnel 11 into the cavity below the funnel 11 of the recovery box 1 for storage, then open the tap 15 to discharge the electrolyte and send it into the evaporation crystallization device for evaporation crystallization treatment, and at the same time open the box door 18 on the recovery box 1, pull out the latch 307 to release the fixation between the clamp 304 and the fixing seat 302, then take out the filter cartridge 308 from the recovery box 1, pour out the solid debris in it, put the filter cartridge 308 back into the recovery box 1 and reinsert the clamp 304 into the card slot 303, align the pin hole 305 on the clamp 304 with the through hole 306, reinsert the latch 307 between the two, and re-fix the filter cartridge 308 on the fixing seat 302;

[0076] S7, structural restoration: The electric push rod 301 extends to drive the lower tube 505, the filter cartridge 308 and the water distribution tank 204 to restore their positions, and the next recycling can be carried out. Specifically, 310 extends to drive the filter cartridge 308 to descend, and at the same time, the descending U-shaped frame 17 drives the second rack 508 to descend, and drives the third rack 510 to rise through the second gear 509. The third rack 510 drives the upper tube 504 and the lower tube 505 to rise until the position is restored. At this time, the third magnet 502 is magnetically attracted to the iron block 503, and the second rack 508 that continues to descend is disengaged from the second gear 509. The U-shaped frame 17 will also drive the second magnet 212 to descend through the extension rod 213. When the second magnet 212 and the iron plate 209 are released from magnetic attraction, the descending second magnet 212 presses down the iron plate 209 to release the magnetic attraction between it and the two first magnetic blocks 211. The iron plate 209 that continues to descend drives the first rack 208 to descend and engage with the first gear 201 to rotate. The rotating first gear 201 drives the slide rail 202 to deflect, and the original high end becomes the low end, and the bottom end becomes the high end. Then the U-shaped slide seat 203 slides from high to low, driving the water distribution tank 204 to restore its position, and then the next recycling can be carried out.
