Description

Technical Field

[0001] This utility model relates to the field of electrolyte recycling technology, and in particular to a lithium battery electrolyte recycling structure. Background Technology

[0002] Lithium-ion batteries are widely used in electronic products, new energy vehicles, and energy storage due to their advantages such as high energy density, long lifespan, and low self-discharge. Electrolyte is an important component of lithium-ion batteries, mainly composed of lithium salts, organic solvents, and additives. The main component of lithium salt is LiPF6, which is easily decomposed into harmful substances such as HF and POF3 when it comes into contact with moisture in the air. These substances can seriously endanger human health and the environment. Therefore, electrolyte recycling is necessary to reduce resource waste and protect the environment.

[0003] Currently, traditional electrolyte recycling systems typically involve crushing the batteries before processing waste lithium batteries to separate the battery fragments from the electrolyte. However, during this separation process, some tiny battery fragments can clog the mesh frame, reducing the electrolyte flow rate and thus prolonging the overall recycling process time. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a lithium battery electrolyte recovery structure, which aims to improve the existing technology's inability to prevent tiny battery fragments from clogging the filter pores, and the problem that impurities easily accumulate during secondary separation.

[0007] The vibration assembly includes a second motor, which is fixedly connected to the outside of the housing. A cam is fixedly connected to the output end of the second motor. Multiple first springs are fixedly connected inside the housing. A mesh frame is fixedly connected to the top of each first spring. Two second springs are fixedly connected to the bottom of the mesh frame. The bottom ends of the two second springs are fixedly connected to the bottom wall of the inner housing. Multiple sliders are fixedly connected to the outside of the mesh frame. The sliders are slidably connected inside the housing. A guide plate is fixedly connected to the outside of the mesh frame.

[0008] As a further description of the above technical solution:

[0009] The anti-clogging component includes a motor three, the bottom of which is fixedly connected to the top of the filter cartridge. A disc is fixedly connected to the output end of the motor three, and a cylinder is fixedly connected to the outer side of the disc. A frame is fitted around the outer periphery of the cylinder, and a connecting rod is fixedly connected to the bottom of the frame. Multiple scrapers are fixedly connected to the outer periphery of the connecting rod, and the multiple scrapers are slidably connected to the inner wall of the filter screen.

[0010] As a further description of the above technical solution:

[0011] The crushing assembly includes two crushing rollers, both of which are rotatably connected inside the feeding hopper. Gears are fixedly connected to the outer sides of both crushing rollers, and the two gears are meshed together. The gears are rotatably connected to the outer side of the feeding hopper. A support is fixedly connected to the outer side of the outer shell, and a motor is fixedly connected to the top of the support. The output end of the motor is fixedly connected to the middle of one of the gears.

[0012] As a further description of the above technical solution:

[0013] The collection assembly includes a box, with two slide rails fixedly connected to the bottom wall of the box, and a collection frame slidably connected to the top of the two slide rails. The collection frame is slidably connected inside the box.

[0014] As a further description of the above technical solution:

[0015] Two magnets are fixedly connected inside the box, and magnets are fixedly connected inside the two slide rails. The magnets are magnetically attracted to each other.

[0016] As a further description of the above technical solution:

[0017] A drain pipe is fixedly connected to the outside of the filter cylinder, a sewage pipe is fixedly connected to the bottom of the filter screen, and the filter screen is fixedly connected to the inside of the filter cylinder.

[0018] As a further description of the above technical solution:

[0019] The outer side of the cam abuts against the bottom of the mesh frame;

[0020] As a further description of the above technical solution:

[0021] The connecting rod passes through and slides inside the filter cylinder.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, after the pulverized battery fragments and electrolyte fall to the top of the mesh frame, the second motor drives the cam to rotate. When the cam protrusion lifts the mesh frame, springs one and two are stretched. When the protrusion moves away from the mesh frame, springs one and two pull the mesh frame back to its original position. Thus, the continuous rotation of the cam causes the mesh frame to vibrate continuously, which can accelerate the separation of battery fragments and electrolyte, prevent the filter holes from being blocked by small fragments, and ensure the efficiency of electrolyte passage.

[0024] 2. In this utility model, after the electrolyte is initially separated, it falls into the filter cylinder through the connecting pipe for secondary filtration. The starting motor drives the disc to rotate, which in turn causes the cylinder, frame and connecting rod to move together, moving the scraper on the inner wall of the filter screen. As the disc continues to rotate, the frame drives the connecting rod to move back and forth up and down, causing the scraper to slide in a circular motion inside the filter screen, keeping the impurities in a constant state of flow, thereby effectively preventing the filter screen pores from clogging and ensuring the efficient and stable operation of the secondary filtration.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-5 This utility model provides an embodiment of a lithium battery electrolyte recovery structure, including a feeding funnel 1, a shell 6 fixedly connected to the bottom of the feeding funnel 1, support columns 10 fixedly connected to the four corners of the bottom of the shell 6, and a base 11 fixedly connected to the bottom of the multiple support columns 10. The support columns 10 and the base 11 are used to support the overall equipment and ensure that the equipment remains stable during operation. A connecting pipe 13 is fixedly connected to the bottom of the shell 6, and a filter cylinder 12 is fixedly connected to the bottom of the connecting pipe 13. After initial separation, the electrolyte flows into the filter cylinder 12 through the connecting pipe 13 for secondary filtration. A fixing ring 27 is fixedly connected inside the filter cylinder 12, and a filter screen 30 is fixedly connected to the middle of the fixing ring 27. The fixing ring 27 is used to allow the electrolyte to flow smoothly into the filter screen 30. Support columns 25 are fixedly connected to the bottom of the filter cylinder 12, and the bottoms of the multiple support columns 25 are fixedly connected to the top of the base 11. A vibration component is provided inside the shell 6, an anti-clogging component is provided at the top of the filter cylinder 12, a crushing component is provided inside the feeding funnel 1, and a collection component is provided on the outside of the shell 6.

[0036] The vibration assembly includes a second motor 7, which is fixedly connected to the outside of the outer casing 6. When the second motor 7 is started, it converts electrical energy into mechanical kinetic energy, thereby driving the cam 26 to rotate at its output end. The output end of the second motor 7 is fixedly connected to the cam 26. Multiple first springs 23 are fixedly connected inside the outer casing 6. A mesh frame 21 is fixedly connected to the top of each first spring 23, and two second springs 24 are fixedly connected to the bottom of the mesh frame 21. The bottom ends of both second springs 24 are fixedly connected to the inner bottom wall of the outer casing 6. When the cam 26 rotates, its protruding edge contacts the mesh frame 21 due to rotation, thus pushing the mesh frame 21 upwards. During this upward movement, the mesh frame 21 stretches the first springs 23 and the second springs 24. When the protruding part moves away from the mesh frame 21, the first springs 23 and 24... 3 and spring 24 will generate a restoring force, thereby driving the mesh frame 21 to move downward, thus creating a vibration. The cam 26 driven by motor 7 will rotate continuously, which can make the mesh frame 21 vibrate repeatedly, thereby accelerating the separation process of battery fragments and electrolyte. The vibration can also prevent fragments from clogging the mesh frame 21 and avoid affecting the electrolyte flow rate. Multiple sliders 25 are fixedly connected to the outside of the mesh frame 21. The multiple sliders 25 are slidably connected inside the outer shell 6. By setting the sliders 25, it can be ensured that the mesh frame 21 can move vertically up and down, preventing the mesh frame 21 from shaking in other directions. A guide plate 22 is fixedly connected to the outside of the mesh frame 21. The separated battery fragments will slide down the mesh frame 21 to the guide plate 22, and then fall into the next area through the guide plate 22.

[0037] Reference Figure 2 , Figure 3 and Figure 6 The anti-clogging component includes a motor 16. The motor 16 can convert electrical energy into mechanical energy. The bottom of the motor 16 is fixedly connected to the top of the filter cylinder 12. The output end of the motor 16 is fixedly connected to a disc 17. A cylinder 18 is fixedly connected to the outside of the disc 17. A frame 19 is fitted around the outer periphery of the cylinder 18. A connecting rod 20 is fixedly connected to the bottom of the frame 19. Multiple scrapers 28 are fixedly connected to the outer periphery of the connecting rod 20. The multiple scrapers 28 are slidably connected to the inner wall of the filter screen 30. The motor 16 can drive the disc 17 and the cylinder 18 on its outer side to rotate together. Then the cylinder 18 will drive the frame 19 to move together with the cylinder 18. With the continuous rotation of the cylinder 18, the frame 19 can drive the connecting rod 20 to move up and down repeatedly, thereby driving the scrapers 28 to move up and down repeatedly as well. This keeps the impurities inside the filter screen 30 in a flowing state, preventing small impurities from clogging the filter holes of the filter screen 30.

[0038] Reference Figure 1The crushing assembly includes two crushing rollers 2, both of which are rotatably connected inside the feeding hopper 1. Gears 3 are fixedly connected to the outer sides of both crushing rollers 2, and the two gears 3 are meshed together. The gears 3 are rotatably connected to the outer side of the feeding hopper 1. A support 5 is fixedly connected to the outer side of the outer shell 6, and a motor 4 is fixedly connected to the top of the support 5. The output end of the motor 4 is fixedly connected to the middle of one of the gears 3. The waste lithium battery is poured into the feeding hopper 1, and then the motor 4 is started. The motor 4 drives the gear 3 connected to it to rotate. Since the two gears 3 are meshed, the rotation of one gear 3 will drive the other gear 3 to rotate, thereby driving the two crushing rollers 2 to rotate, thereby crushing the waste lithium battery and separating the electrolyte.

[0039] Reference Figure 7 The collection component includes a housing 8, with two slide rails 33 fixedly connected to the bottom wall of the housing 8. A collection frame 9 is slidably connected to the top of the two slide rails 33. The collection frame 9 is slidably connected inside the housing 8. The collection component is used to collect broken battery fragments. Battery fragments that fall into the housing 8 will fall into the collection frame 9 and then be centrally processed. By setting up the collection frame 9, battery fragments can be effectively collected, thereby saving resources and avoiding environmental pollution from battery fragments.

[0040] Reference Figure 7 Inside the housing 8, two magnets 31 are fixedly connected, and inside each of the two slide rails 33, magnets 32 are fixedly connected. Magnets 31 and 32 are magnetically attracted to each other. The outward-facing side of magnet 31 is set as the S pole, and the outward-facing side of magnet 32 ​​is set as the N pole. Through the principle of "opposites attract", magnets 31 and 32 can be attracted together. Thus, when the equipment is running, the collection frame 9 can be firmly held inside the housing 8 by the attraction between magnets 31 and 32, ensuring that the collection frame 9 will not accidentally detach from the housing 8 when the equipment is running.

[0041] Reference Figure 6 A drain pipe 14 is fixedly connected to the outside of the filter cylinder 12. The drain pipe 14 is used to discharge the filtered electrolyte. A sewage pipe 29 is fixedly connected to the bottom of the filter screen 30. The sewage pipe 29 is used to discharge the impurities inside the filter screen 30. The filter screen 30 is fixedly connected inside the filter cylinder 12.

[0042] Reference Figure 4 The outer side of the cam 26 abuts against the bottom of the mesh frame 21. The protruding part of the cam 26 repeatedly contacts the mesh frame 21, causing the mesh frame 21 to vibrate, thereby accelerating the separation rate.

[0043] Reference Figure 6 The connecting rod 20 passes through and slides inside the filter cylinder 12. When the connecting rod 20 is moved, it will slide inside the filter cylinder 12.

[0044] Working principle: First, the crushed battery fragments and electrolyte fall onto the mesh frame 21. Motor 7 is then activated, driving cam 26 to rotate. The protruding part of cam 26 touches the mesh frame 21, causing it to move upwards. During this upward movement, springs 23 and 24 are stretched. This stretching pulls the mesh frame 21 in the opposite direction. Therefore, when the protruding part of cam 26 moves away from the bottom of the mesh frame 21, springs 23 and 24 cause the mesh frame 21 to move downwards, creating a vibration effect. Continuous rotation of cam 26 causes the mesh frame 21 to vibrate repeatedly, accelerating the separation of battery fragments and electrolyte. This also effectively prevents the filter pores of the mesh frame 21 from being clogged by tiny fragments, thus affecting the electrolyte flow rate.

[0045] When the electrolyte is initially separated, it falls into the filter cylinder 12 through the connecting pipe 13 for secondary filtration. The motor 16 is started, which drives the disc 17 to rotate. The disc 17 drives the cylinder 18 to rotate, and then the frame 19 moves with the cylinder 18. When the frame 19 moves, it drives the connecting rod 20 to move. Then, the connecting rod 20 drives the scraper 28 to move on the inner wall of the filter screen 30. The disc 17 drives the cylinder 18 to rotate continuously, which makes the frame 19 drive the connecting rod 20 to move up and down repeatedly, so that the scraper 28 moves back and forth, ensuring that the impurities in the filter screen 30 are always in a flowing state and preventing impurities from clogging the filter holes of the filter screen 30.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
