Description

Technical Field

[0001] This invention belongs to the field of lithium battery recycling technology, and specifically relates to a lithium battery recycling puncture discharge device. Background Technology

[0002] When recycling lithium batteries, since there is often a certain amount of residual charge inside, directly crushing the lithium battery can easily cause fires or explosions. In order to improve the safety of lithium batteries during recycling, before crushing the lithium battery, a steel needle must be inserted vertically from top to bottom through the lithium battery to create a short circuit inside the lithium battery, thereby achieving the purpose of rapid discharge.

[0003] The common method currently used is to manually puncture the lithium battery with a steel needle to short-circuit it and discharge it. However, this process is extremely prone to triggering thermal runaway, causing a short-range explosion and splashing of toxic electrolyte. Manual operation poses a significant safety risk. Existing automated processing equipment mostly uses open or semi-open puncture methods, which also face the problems of injury from explosive shock waves, contamination from poor-quality electrolyte, and the spread of fire. In addition, since some lithium batteries contain liquid electrolyte, which is corrosive, the electrolyte inside the lithium battery is prone to leakage during puncture, which can corrode the puncture equipment. Furthermore, if the lithium battery unfortunately explodes, the electrolyte splashed to the outside can easily threaten nearby operators, which is not conducive to the requirements of safe production.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The present invention is equipped with a rotating disk, a cylindrical support and a high-temperature resistant elastic scraper, etc. When in use, the lithium batteries are fed into the storage tank of the rotating disk one by one through the feed port by the conveyor belt. The rotating disk is driven by the motor to rotate, which drives the lithium batteries in the storage tank to move horizontally to the bottom of the steel needle. Then the hydraulic cylinder drives the steel needle to move down through the lifting plate to complete the puncture. Since the lithium battery is located inside the storage tank at this time, the fragments generated by the explosion and the splashed electrolyte adhere to the inner wall of the cylindrical support and the storage tank. At the same time, the high pressure generated by the explosion is directly discharged through the through hole above. As the rotation continues, the high-temperature resistant elastic scraper scrapes off and cleans the attached debris, so as to achieve the purpose of automated puncture discharge and safe explosion suppression.

[0017] (2) The present invention is provided with an air pipe, a first movable rod and a second movable rod. When the hydraulic cylinder drives the steel needle to move down through the lifting plate, it also drives the first movable rod to gradually embed into the air pipe, thereby squeezing the gas inside the air pipe and causing it to move towards the second movable rod, thereby pushing the second movable rod to move up, forcing the lifting frame to rise as the steel needle continues to move down, causing the activated carbon sponge sleeve to come into contact with the inner wall of the storage tank, and using the activated carbon sponge sleeve to absorb the electrolyte adhering to the inner wall of the storage tank, thereby improving the cleaning effect.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-4As shown, the present invention provides the following technical solution: A lithium battery recycling puncture discharge device includes a cylindrical support 2. A motor 19 and a rotating disk 1 are disposed inside the cylindrical support 2. The motor 19 is fixedly installed in the center of the cylindrical support 2, and the output end of the motor 19 is fixedly connected to the rotating disk 1. The rotating disk 1 is rotatably disposed inside the cylindrical support 2 via the motor 19. Storage slots 11 are evenly spaced on the lower part of the side wall of the rotating disk 1. An inlet 9 is provided on the side wall of the cylindrical support 2, and an outlet 25 is provided on the inner wall of the cylindrical support 2 near one side. The top of the rotating disk 1 is provided with through holes 15 at equal intervals, which are connected to the storage tank 11. The bottom of the cylindrical support 2 is provided with four extension plates 3 at equal intervals. The bottom of the extension plates 3 is fixedly installed with support columns 5, and hydraulic cylinders 10 are fixedly installed on two extension plates 3 on one side. The output ends of the two hydraulic cylinders 10 are connected through lifting plates 12. The lifting plates 12 are located above the through holes 15, and steel needles 13 are fixedly installed in the center of the bottom of the lifting plates 12.

[0030] The above technical solution involves the following steps: In use, lithium batteries are fed one by one into the storage tank 11 on the rotating disk 1 through the inlet 9 using a conveyor belt or similar transport device. Then, the rotating disk 1 is rotated by the motor 19, causing the inner wall of the cylindrical support 2 to close the opening of the storage tank 11. Simultaneously, the lithium batteries are moved horizontally to below the steel needle 13 and then the rotation stops. Afterward, the hydraulic cylinder 10, via the lifting plate 12, moves the steel needle 13 downward, causing it to penetrate the storage tank 11 through the through hole 15 and pierce the lithium battery. Since the lithium battery is located in the storage tank 11 at this time... Even if an explosion occurs within the enclosed space of 1, the fragments and splashed electrolyte generated by the explosion cannot spread outwards. Instead, they fall and adhere to the inside of the storage tank 11. Simultaneously, the high-pressure gas generated by the explosion is discharged directly outwards through the through hole 15 above. As the rotating disk 1 continues to rotate, the punctured lithium battery moves horizontally above the discharge port 25. Under the action of gravity, the lithium battery falls downwards through the discharge port 25 and then moves to the outside of the cylindrical support 2, achieving the effect of automated puncture and eliminating the problem of easy injury to the operator during puncture explosion.

[0031] Furthermore, an installation groove 23 is provided on the outer wall of the rotating disk 1. The installation groove 23 is located around the material storage trough 11, and a high-temperature resistant elastic scraper 24 is fitted inside the installation groove 23. The end of the high-temperature resistant elastic scraper 24 is in contact with the inner wall of the cylindrical support 2.

[0032] Please refer to Figures 2-3 and Figure 8After the puncture is completed, as the rotating disk 1 continues to rotate, the activated carbon sponge strip also slides inside the cylindrical support 2. Since the end of the high-temperature resistant elastic scraper 24 is in contact with the inner wall of the cylindrical support 2, the debris generated by the explosion can be swept away while rotating, so that it moves synchronously with the lithium battery inside the cylindrical support 2 and finally falls synchronously to the outside of the equipment through the discharge port 25. In addition, while the high-temperature resistant elastic scraper 24 is sliding, it also absorbs the electrolyte that adheres to the inner wall of the cylindrical support 2 after the explosion, preventing the electrolyte from corroding the cylindrical support 2 and causing its strength to gradually decrease.

[0033] Furthermore, an L-shaped cleaning groove 6 is provided on the side wall of the cylindrical support 2. The cleaning groove 6 is located beside the feed inlet 9 and is away from the steel needle 13. The top of the inner wall of the cleaning groove 6 is flush with the top of the inner wall of the storage tank 11. A lifting frame 16 is slidably installed inside the cleaning groove 6. The lifting frame 16 is fixedly connected to the cylindrical support 2 through a lifting assembly. The lifting frame 16 is embedded into the storage tank 11 through the cleaning groove 6. An activated carbon sponge sleeve 4 is wrapped around the outer wall of the lifting frame 16. The activated carbon sponge sleeve 4 is in contact with the inner wall of the storage tank 11. The lifting assembly includes an air pipe 7, which is fixedly installed on the cylindrical support 2. On the side wall of the bracket 2, and at both ends of the air tube 7, extend to the lower part of the lifting plate 12 and the lifting frame 16 respectively. Two first movable rods 14 are symmetrically installed at the bottom of the lifting plate 12. The first movable rods 14 are located on both sides of the steel needle 13, and the ends of the first movable rods 14 are slidably sealed inside the air tube 7. Two second movable rods 17 are symmetrically installed at the top of the inner wall of the lifting frame 16. The second movable rods 17 are slidably sealed inside the air tube 7. The outer wall of the end of the first movable rod 14 and the second movable rod 17 embedded inside the air tube 7 is fixedly installed with a circular sealing ring 28. The circular sealing ring 28 is in contact with the inner wall of the air tube 7.

[0034] Please refer to Figures 1-2 and Figure 7While the hydraulic cylinder 10 drives the steel needle 13 downward to puncture through the lifting plate 12, it also simultaneously drives the first movable rod 14 downward, so that the first movable rod 14 gradually embeds into the inside of the air pipe 7, thereby squeezing the gas inside the air pipe 7, forcing the gas to move towards the direction of the second movable rod 17, and pushing the second movable rod 17 upward, driving the lifting frame 16 to embed into the storage tank 11 through the cleaning tank 6, so that the activated carbon sponge sleeve 4 comes into contact with the inner wall of the storage tank 11, and adsorbs the electrolyte adhering to the inner wall of the storage tank 11. With the help of the high-temperature resistant elastic scraper 24, the leaked electrolyte is completely adsorbed and cleaned, so that cleaning and puncture are carried out simultaneously, improving the working efficiency of large-volume discharge. After the puncture is completed, the steel needle 13 moves upward. At this time, the gas inside the air pipe 7 moves towards the steel needle 13, forcing the second movable rod 17 to move downward, driving the lifting frame 16 to move to the outside of the storage tank 11, and releasing the locking of the cylindrical support 2.

[0035] Furthermore, since the lifting of the lifting frame 16 and the piercing of the steel needle 13 are carried out simultaneously, if the pierced lithium battery explodes, the lifting frame 16 is located inside the cleaning tank 6 at this time, and the upper end of the lifting frame 16 is embedded inside the storage tank 11. Under the obstruction of the lifting frame 16, the rotating disk 1 cannot rotate inside the first movable rod 14, so that the shock wave generated by the lithium battery explosion cannot drive the rotating disk 1 to rotate. This prevents the rotating disk 1 from rotating on its own and causing damage to the motor 19, ensuring that the equipment can operate efficiently for a long time.

[0036] Furthermore, the height of the lifting frame 16 is greater than the height of the storage trough 11, and the width of the cleaning trough 6 is greater than the maximum width of the high-temperature resistant elastic scraper 24.

[0037] Please refer to Figures 1-2 Since the width of the cleaning tank 6 is greater than the maximum width of the high-temperature resistant elastic scraper 24, and the high-temperature resistant elastic scraper 24 is fitted inside the mounting slot 23, after the equipment has been used for a long time, maintenance personnel can directly contact the high-temperature resistant elastic scraper 24 through the cleaning tank 6 and pull it out of the mounting slot 23 for replacement. This ensures the cleaning effect while also facilitating maintenance.

[0038] Furthermore, an adjusting ring 18 is movably connected to the outer wall of the steel needle 13. The adjusting ring 18 is slidably disposed inside the extrusion cylinder 22. A through hole 21 is opened at the bottom of the inner wall of the extrusion cylinder 22. The through hole 21 is located directly below the steel needle 13. A high-temperature resistant flexible scraper ring 27 is installed on the inner wall of the through hole 21. The high-temperature resistant flexible scraper ring 27 is in interference fit with the outer wall of the steel needle 13. A first spring 8 is fixedly installed at the bottom of the inner wall of the extrusion cylinder 22. The other end of the first spring 8 is fixedly connected to the bottom of the adjusting ring 18.

[0039] Please refer to Figure 2 and Figures 5-6 Since the extrusion cylinder 22 and the adjusting ring 18 are connected by the first spring 8, the extrusion cylinder 22 moves downward under the influence of the first spring 8, so that the end of the steel needle 13 is always inside the extrusion cylinder 22. During piercing, the extrusion cylinder 22 and the steel needle 13 pass through the through hole 15 simultaneously. At this time, the bottom of the extrusion cylinder 22 contacts the top of the lithium battery first. As the steel needle 13 drives the adjusting ring 18 to move downward, the adjusting ring 18 continues to squeeze the first spring 8, causing its elastic force to gradually increase, which greatly increases the downward pressure of the extrusion cylinder 22 on the lithium battery, thereby achieving the purpose of fixing the lithium battery. The steel needle 13 pierces into the lithium battery through the through hole 21 on the extrusion cylinder 22 to achieve the purpose of piercing.

[0040] In addition, since a high-temperature resistant flexible scraper ring 27 is provided inside the through hole 21, when the end of the steel needle 13 retracts back into the extrusion cylinder 22 after puncture, the high-temperature resistant flexible scraper ring 27 is used to perform interference scraping cleaning on the steel needle 13, forcibly scraping off the attached high-temperature electrolyte and debris, and preventing the problem of electrolyte sticking and jamming the steel needle 13.

[0041] Furthermore, an adjustment groove 26 is provided on the lower part of the outer wall of the steel needle 13. The adjustment groove 26 is a straight groove and is provided with a limiting slot. A protrusion 20 is fixedly installed on the inner wall of the adjustment ring 18. The protrusion 20 is slidably disposed inside the adjustment groove 26.

[0042] Please refer to Figure 5 Before use, the operator can squeeze the first spring 8 by rotating the squeezing cylinder 22, which will force the adjusting ring 18 to rotate, change the position of the protrusion 20, and allow it to slide up and down inside the adjusting groove 26 and eventually be embedded in other slots, thereby adjusting the distance between the end of the steel needle 13 and the through hole 21 to achieve the effect of adjusting the puncture depth.

[0043] Furthermore, a protruding plate 29 is fixedly installed on the center of one side of the lifting plate 12, and a control rod 30 is installed at the bottom of the protruding plate 29. The control rod 30 is located beside the cylindrical bracket 2. A detection hole 32 is opened on the inner wall of the cylindrical bracket 2, and the detection hole 32 is located directly below the protruding plate 29. An infrared temperature detector 31 is fixedly installed on the outer wall of the cylindrical bracket 2. A counter is installed on the top of the infrared temperature detector 31, and the infrared temperature detector 31 is in a normally open continuous monitoring state. The control rod 30 is located directly above the counter. The detection end of the infrared temperature detector 31 is aligned with the end of the steel needle 13 through the detection hole 32. The output end of the infrared temperature detector 31 is connected to the display through a data cable.

[0044] Please refer to Figures 1-2 and Figure 4When the hydraulic cylinder 10 moves the lifting plate 12 and the steel needle 13 downwards, it simultaneously drives the protruding plate 29 and the control rod 30 downwards. The control rod 30 then squeezes the counter, which is used to record the number of punctures. During puncture, the infrared temperature detector 31 is aligned with the end of the steel needle 13. During the puncture, the chemical reaction inside the lithium battery may release a large amount of heat instantly, causing the local temperature to rise rapidly. At this time, the temperature change around the lithium battery is also quite drastic. The infrared temperature detector 31 can detect the change in the ambient temperature around the lithium battery in real time to determine whether the lithium battery has been punctured and discharged. This information is then displayed visually on an external screen to help the operator confirm the effect of the lithium battery puncture and discharge.

[0045] Furthermore, a rotating plate 35 is rotatably arranged inside the lower part of the discharge port 25. A rotating shaft 38 is installed in the middle of both sides of the rotating plate 35. A tension spring 37 is sleeved on the rotating shaft 38, and the other end of the rotating shaft 38 is fixedly connected to the inner wall of the discharge port 25. The two ends of the tension spring 37 are fixedly connected to the inner wall of the discharge port 25 and the side wall of the rotating plate 35, respectively. The top surface of the rotating plate 35 is inclined, and a slot 36 is opened on the side wall of the rotating plate 35. A sponge layer 33 is placed inside the slot 36, and the slot 36 is located below the storage tank 11. The width of the rotating plate 35 is smaller than the width of the storage tank 11, and a liquid injection port 34 is opened at the bottom of the rotating plate 35, which is connected to the slot 36.

[0046] Please refer to Figure 4 and Figure 9 Because the lithium battery explodes after being punctured, it produces a lot of debris, which is much lighter than the unexploded lithium battery. After the lithium battery is punctured, the rotating disk 1 rotates and pushes the lithium battery to the discharge port 25, where it contacts the top surface of the rotating plate 35. Due to the difference in mass, the exploded lithium battery cannot force the rotating plate 35 to rotate downwards. It can only slide through the discharge port 25 to the side of the cylindrical support 2 by relying on the inclined surface. The unexploded lithium battery, under the influence of its mass, directly pushes the rotating plate 35 and falls through the discharge port 25 to the bottom of the cylindrical support 2, thus achieving the effect of sorting and processing lithium batteries.

[0047] Before use, a water pipe can be connected to the injection port 34. Water flows through the injection port 34 into the rotating plate 35 and comes into contact with the sponge layer 33. After the exploded lithium battery slides along the inclined surface to the outside of the cylindrical support 2, the rotating plate 35 starts to rotate under the action of gravity, forcing the sponge layer 33 to slide upward and embed into the inside of the storage tank 11. At this time, the moist sponge layer 33 can evenly coat the inner wall of the storage tank 11 with liquids such as alcohol and water to help the storage tank 11 cool down quickly.

[0048] In addition, the rotation of the rotating disk 1 also drives the high-temperature resistant elastic scraper 24 to move, which pushes the debris generated by the lithium battery puncture and explosion into the interior of the discharge port 25 and falls onto the top surface of the sponge layer 33. As the lithium battery slides, the rotating plate 36 starts to rotate, and the top surface of the sponge layer 33 also begins to tilt. At this time, the debris can slide through the discharge port 25 to the outside of the equipment under the action of gravity, thus achieving the purpose of material discharge.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
