Description

Technical Field

[0001] The present invention relates to the technical field of used battery recycling, and particularly to a resource recycling and separation device for waste lithium batteries. Background Art

[0002] There are many types of used batteries, such as lithium-ion batteries, dry batteries, nickel-metal hydride batteries, etc. The internal structures of different types of batteries are different, and the materials that make up the batteries are also different. For example, a lithium-ion battery generally includes a casing, a positive electrode, a negative electrode, a separator, and an organic electrolyte. The positive electrode material includes a positive electrode metal sheet and an active substance attached to the positive electrode metal sheet, and this active substance is generally lithium manganate, lithium cobaltate, or lithium nickel cobalt manganate material; the negative electrode material includes a negative electrode metal sheet and a negative electrode active substance attached to the negative electrode metal sheet, and this negative electrode active substance is generally graphite or carbon with a graphite-like structure. The negative electrode material is a zinc sheet, etc. For different types of used batteries, generally, they are first classified and collected, and then classified for treatment to be recycled.

[0003] During the existing separation and precipitation process of used batteries, only single-direction stirring is carried out. The single stirring direction may not be able to mix the battery waste liquid and the precipitate well, resulting in poor separation effect, uneven precipitates, and unable to suspend all the precipitates in the waste liquid, causing some precipitates to not completely settle down, affecting subsequent treatment steps, and increasing the energy consumption of the equipment because more energy is required to achieve uniform stirring during the mixing process.

Detailed implementation mode

[0036] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Refer to Figures 1 - 10, this technical solution provides a resource recycling and separation device for waste lithium batteries, specifically including a precipitation tank 1. A separation mechanism 2 is installed inside the precipitation tank 1. Discharge doors are provided on both sides of the precipitation tank 1, and the battery solution after precipitation is discharged through the discharge doors. The separation mechanism 2 includes through grooves 201, a first mounting plate 204, electric telescopic rods 206, and a cross plate 208. There are two through grooves 201, and a first connecting rod 202 is slidably installed inside the two through grooves 201. There are two first connecting rods 202, and first floats 203 are fixedly installed at the bottoms of the two first connecting rods 202. A slide rail 218 is slidably installed on the surfaces of the two first connecting rods 202. When the liquid level inside the precipitation tank 1 gradually rises, the first floats 203 can drive the two first connecting rods 202 to move upward. The upward movement of the first connecting rods 202 can drive the slide rail 218 to move upward. The first mounting plate 204 is fixedly installed at the top of the inner cavity of the precipitation tank 1, and toothed plates 205 are fixedly installed on both sides of the first mounting plate 204. The electric telescopic rods 206 are fixedly installed inside the through grooves 201, and a second mounting plate 207 is fixedly installed at the end of the electric telescopic rods 206. The second mounting plate 207 is slidably connected to the slide rail 218. The cross plate 208 is rotatably installed at the bottom of the second mounting plate 207. A first gear 209 is slidably installed on the surface of the cross plate 208. The first gear 209 meshes with the toothed plate 205. Circular plates 210 are fixedly installed on both the upper and lower sides of the first gear 209. The circular plates 210 are arranged on the upper and lower sides of the toothed plate 205, and the circular plates 210 are slidably connected to the cross plate 208. A connecting plate 211 is fixedly installed at the bottom of the cross plate 208, and a stirring plate 212 is fixedly installed at the bottom of the connecting plate 211. When the electric telescopic rod 206 drives the second mounting plate 207 to slide inside the slide rail 218, the sliding second mounting plate 207 can drive the first gear 209 and the cross plate 208 to move horizontally inside the precipitation tank 1. When the liquid level inside the precipitation tank 1 rises, the slide rail 218 can drive the second mounting plate 207 and the cross plate 208 to slide upward together. The cross plate 208 is slidably connected to the circular plates 210 and the first gear 209. Therefore, when the cross plate 208 moves, the two circular plates 210 clamp the toothed plate 205, so that the positions of the two circular plates 210 inside the precipitation tank 1 remain unchanged, and thus the position height of the first gear 209 will not change. Therefore, when the liquid level height changes, driven by the electric telescopic rod 206, the second mounting plate 207 moves, and then drives the cross plate 208 to move. When the moving cross plate 208 moves, it can drive the first gear 209 to move. When the first gear 209 moves, under the action of the toothed plate 205, the first gear 209 rotates simultaneously. Therefore, the stirring plate 212 can move horizontally inside the precipitation tank 1 and also rotate, thereby fully stirring the solution inside the precipitation tank 1.At the top of the precipitation tank 1, an additive storage barrel 213 is fixedly installed. There are two additive storage barrels 213, and both of the two additive storage barrels 213 are communicated with the precipitation tank 1. Additives are stored inside the additive storage barrel 213. The additives can cause a chemical reaction in the battery solution, enabling a displacement reaction of the recoverable metals in the battery solution, and the metals precipitate at the bottom of the precipitation tank 1. At the top of the precipitation tank 1, a filter tank 214 is fixedly installed. The filter tank 214 is communicated with the precipitation tank 1. Inside the filter tank 214, a filter plate 215 is fixedly installed. The filter plate 215 is arranged in a conical shape. There are three filter plates 215. The arrangement of the conical filter plate 215 can allow the battery mixture to be filtered out from the side of the cone, while leaving the battery waste residue at the bottom of the cone, which can avoid the situation that a flat filter plate 215 is easily blocked. The arrangement of multiple filter plates 215 can perform multiple filtrations on the filtrate, making the filtered solution cleaner. Inside the top filter plate 215, a first rotating rod 216 is rotatably installed. The first rotating rod 216 penetrates to the top of the bottom filter plate 215. The first rotating rod 216 is rotatably connected to all three filter plates 215. Scrapers 217 are rotatably installed on the surfaces of the three filter plates 215. The scrapers 217 are fixedly connected to the first rotating rod 216. When the first rotating rod 216 rotates, the rotating first rotating rod 216 can drive the scrapers 217 to rotate. The rotating scrapers 217 can scrape the battery waste residue on the surface of the filter plate 215, preventing the filtrate from being blocked on the filter plate 215.,

[0038] Refer to Figures 1 - 10, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that an immersion mechanism 3 is installed on the top of the filtration box 214. The immersion mechanism 3 includes an immersion tank 301. A discharge port 302 is opened at the bottom of the immersion tank 301. The immersion tank 301 is communicated with the filtration box 214 through the discharge port 302. The used battery mixture after being immersed in the immersion tank 301 falls into the interior of the filtration box 214 through the discharge port 302 for filtration. A second rotating rod 303 is rotatably installed inside the discharge port 302. There are two second rotating rods 303. Baffles 304 are fixedly installed on the surfaces of the two second rotating rods 303. The baffles 304 can block the used battery mixture to prevent the mixture from falling. First bevel gears 305 are fixedly installed at the ends of the two second rotating rods 303. When the first bevel gear 305 rotates, it can drive the second rotating rod 303 to rotate, and then drive the baffle 304 to rotate. When the rotation angle of the baffle 304 reaches a certain angle, the mixture will fall from the interior of the immersion tank 301. A slide rod 307 is installed inside the left second sliding groove 306. A second float 308 is slidably installed on the surface of the slide rod 307. A mobile magnetic sensor 313 is fixed to the side wall of the second float 308. A magnetic inductor 315 is installed above the left second sliding groove 306, which can detect the approach of the mobile magnetic sensor 313. A switch is installed outside the immersion tank 301. The switch is electrically connected to the fixed magnetic inductor 315 and is configured to be started or closed when receiving the signal sent by the fixed magnetic inductor 315. And the switch is also electrically connected to the motor 314. A driving motor 314 is fixed to the bottom of the immersion tank 301. The output end of the driving motor 314 penetrates the bottom of the immersion tank 301 and is fixed with a first pulley 309. A cross plate 310 is fixedly installed at the top of the discharge port 302. A second pulley 311 is rotatably installed at the top of the cross plate 310. The second pulley 311 is connected to the first pulley 309 by a belt. A second bevel gear 312 is rotatably installed at the bottom of the cross plate 310. The second bevel gear 312 meshes with the first bevel gear 305. When the height of the mixture inside the immersion tank 301 rises, it can drive the second float 308 to move upward. The upward moving second float 308 makes the mobile magnetic sensor 313 approach the magnetic inductor 315 at this time. The magnetic inductor 315 is a switch based on the magnetic principle and usually consists of two triggerable metal sheets with a small gap between them.When the moving magnetic sensor 313 approaches, the influence of the magnetic field causes the metal sheet to close, triggering the switch to act. At this time, the driving motor 314 will be controlled to drive the first pulley 309 to rotate. The first pulley 309 will drive the second pulley 311 to rotate through the belt. The rotating second pulley 311 can drive the second bevel gear 312 to rotate, and then can drive the first bevel gear 305 to rotate. The rotating second bevel gear 312 can also drive the first rotating rod 216 to rotate, and then can drive the scraper 217 to rotate. Further explanation is that the start and stop of the motor 314 are controlled according to the detection of the approach of the moving magnetic sensor 313 by the fixed magnetic inductor 315. When the moving magnetic sensor 313 approaches the preset distance of the fixed magnetic inductor 315, the fixed magnetic inductor 315 sends a signal to the switch to cause the switch to change its state to start the motor 315; when the moving magnetic sensor 313 moves away from the fixed magnetic inductor 315, the switch switches to another state to stop the operation of the motor 315.

[0039] Refer to Figures 1 - 10, based on the same concept as the above-mentioned Embodiment 1, this embodiment also proposes that a stirring mechanism 4 is installed on the top of the soaking tank 301. The stirring mechanism 4 includes a second gear 401 which is rotatably installed on the top of the soaking tank 301. A third rotating rod 402 is rotatably installed on the top of the inner cavity of the soaking tank 301. The third rotating rod 402 is fixedly connected to the second gear 401.

There are multiple installation columns 404. Stirring rods 405 are fixedly installed on the surfaces of the multiple installation columns 404. When the second gear 401 rotates, the rotating second gear 401 can drive the third rotating rod 402 to rotate. The rotating third rotating rod 402 can drive the fixing plate 403 to rotate. The rotating fixing plate 403 can drive the installation column 404 to rotate. The rotating installation column 404 can drive the stirring rod 405 to rotate, thereby stirring the top of the mixture. A fourth rotating rod 406 is rotatably installed at the bottom of the fixing plate 403. The bottom of the fourth rotating rod 406 is fixedly connected to the second pulley 311. Fixing columns 407 are fixedly installed on the surface of the fourth rotating rod 406. There are multiple fixing columns 407. Cross bars 408 are fixedly installed on the surfaces of the multiple fixing columns 407. When the second pulley 311 rotates, the rotating second pulley 311 can drive the fourth rotating rod 406 to rotate, thereby driving the cross bar 408 to rotate, and further stirring the bottom of the mixture. And the rotating direction of the cross bar 408 is opposite to that of the stirring rod 405, which will make the soaking of the mixture more complete and accelerate the soaking speed. A third gear 409 is rotatably installed on the top of the soaking tank 301. A fourth gear 410 is rotatably installed on the side of the third gear 409. The third gear 409 is meshed with the second gear 401. The third gear 409 is meshed with the fourth gear 410. A second threaded rod 411 is rotatably installed inside the right second sliding groove 306. The second threaded rod 411 is fixedly connected to the fourth gear 410. An arc-shaped plate 412 is threadedly installed on the surface of the second threaded rod 411. The arc-shaped plate 412 is slidably connected to the second sliding groove 306. A flat plate 413 is fixedly installed on the side of the arc-shaped plate 412. When the second gear 401 rotates, it can drive the third gear 409 to rotate. The rotating third gear 409 can drive the fourth gear 410 to rotate, thereby driving the second threaded rod 411 to rotate, and further driving the arc-shaped plate 412 to move up and down, so as to stir the mixture up and down.

[0040] Refer to Figures 1 - 10, based on the same concept as the above-mentioned Embodiment 1, this embodiment also proposes that an air inlet pipe 414 is fixedly installed on the side of the soaking tank 301. There are two air inlet pipes 414. Pistons 415 are slidably installed inside both of the two air inlet pipes 414. A third threaded rod 416 is fixedly installed on the top of the piston 415. A support plate 417 is threadedly installed on the surface of the third threaded rod 416. A third pulley 423 is rotatably installed on the top of the support plate 417. The third threaded rod 416 is threadedly connected to the third pulley 423. The support plate 417 is fixedly installed on the side of the soaking tank 301. Connecting pipes 418 are fixedly installed at the bottom of both of the two air inlet pipes 414. The connecting pipes 418 extend into the soaking tank 301. Check valves 425 are installed on the connecting pipes 418, which can prevent liquid from being sucked into the air inlet pipes 414. A fifth gear 419 is rotatably installed on the top of the soaking tank 301. There are two fifth gears 419. Both of the two fifth gears 419 are meshed with the second gear 401. Fourth pulleys 424 are fixedly installed on the tops of both of the two fifth gears 419. The third pulley 423 is connected to the fourth pulley 424 by a belt. When the second gear 401 rotates, the rotating second gear 401 can drive the fifth gear 419 to rotate, and then can drive the fourth pulley 424 to rotate. The rotating fourth pulley 424 can drive the third pulley 423 to rotate. The rotating third pulley 423 can move the third threaded rod 416 up and down, and then can drive the piston 415 to reciprocate inside the air inlet pipe 414. The rotation of the third threaded rod 416 can drive a feeding funnel 420 to be arranged on the top of the soaking tank 301. There are two feeding funnels 420. A reciprocating motor 421 is fixedly installed in the middle of both of the two feeding funnels 420. The output end of the reciprocating motor 421 is fixedly connected to the second gear 401. An air outlet pipe 422 is fixedly installed inside the soaking tank 301. The air outlet pipe 422 is communicated with the connecting pipe 418. Gas is generated inside the air inlet pipe 414, and the gas enters into the air outlet pipe 422 from the inside of the connecting pipe 418 to blow the mixture.

[0041] Specifically, the working process or principle of this waste lithium battery resource recycling and separation device is as follows: First, the staff puts waste batteries and the soaking liquid into the interior of the soaking tank 301 through the feeding funnel 420. Then, the reciprocating motor 421 and the electric telescopic rod 206 are started. The reciprocating motor 421 can drive the second gear 401 to rotate. The rotating second gear 401 can drive the third rotating rod 402 to rotate. The rotating third rotating rod 402 can drive the fixing plate 403 to rotate. The rotating fixing plate 403 can drive the mounting column 404 to rotate. The rotating mounting column 404 can drive the stirring rod 405 to rotate, thereby stirring the top of the mixture. When the second gear 401 rotates, it can drive the third gear 409 to rotate. The rotating third gear 409 can drive the fourth gear 410 to rotate, thereby driving the second threaded rod 411 to rotate, and then driving the arc-shaped plate 412 to move up and down, so as to stir the mixture up and down.

[0042] When the height of the waste batteries and the soaking liquid in the soaking tank 301 becomes higher and higher, when the height of the mixture in the soaking tank 301 rises, it can drive the second float 308 to move upward. The upward-moving second float 308 makes the moving magnetic sensor 313 approach the magnetic inductor 315 at this time. The magnetic inductor 315 is a switch based on the magnetic principle and usually consists of two triggerable metal sheets with a small gap between them. When the moving magnetic sensor 313 approaches, the influence of the magnetic field will cause the metal sheets to close, triggering the switch to act. At this time, it will control the driving motor 314 to drive the first pulley 309 to rotate. The first pulley 309 will drive the second pulley 311 to rotate through the belt. The rotating second pulley 311 can drive the fourth rotating rod 406 to rotate, thereby driving the cross bar 408 to rotate, and then stirring the bottom of the mixture. At the same time, the reciprocatingly rotating second gear 401 can drive the fifth gear 419 to rotate, thereby driving the fourth pulley 424 to rotate. The rotating fourth pulley 424 can drive the third pulley 423 to rotate. The rotating third pulley 423 can move the third threaded rod 416 up and down, thereby driving the piston 415 to reciprocate inside the intake pipe 414. The gas generated inside the intake pipe 414 enters the inside of the outlet pipe 422 through the inside of the connecting pipe 418, and then blows the mixture.

[0043] The rotating second pulley 311 can drive the second bevel gear 312 to rotate, and then can drive the first bevel gear 305 to rotate. When the first bevel gear 305 rotates, it can drive the second rotating rod 303 to rotate, and then can drive the baffle 304 to rotate. When the rotation angle of the baffle 304 reaches a certain angle, the mixture will fall from the inside of the soaking tank 301 to the inside of the filtering tank 214. Under the action of the conical filter plate 215, the battery waste residue remains on the top of the filter plate 215, while the battery solution falls into the inside of the precipitation tank 1. At this time, the electric telescopic rod 206 drives the second mounting plate 207 to slide inside the slide rail 218. The sliding second mounting plate 207 can drive the first gear 209 and the cross plate 208 to move horizontally inside the precipitation tank 1. When the first gear 209 moves, under the action of the toothed plate 205, the first gear 209 rotates simultaneously. The rotation of the first gear 209 can drive the cross plate 208 to rotate, and the rotating cross plate 208 can drive the stirring plate 212 to rotate, so as to stir the battery solution inside the precipitation tank 1 and accelerate the precipitation speed.
