Description

Technical Field

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

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become mainstream. The electrolyte in a lithium-ion battery is the carrier of ion transport and is generally composed of lithium salts and organic solvents. The electrolyte plays a role in conducting ions between the positive and negative electrodes, ensuring that lithium-ion batteries achieve advantages such as high voltage and high specific energy. The electrolyte is generally prepared by mixing high-purity organic solvents, lithium salt electrolytes, and necessary additives under certain conditions and in certain proportions.

[0003] However, lithium batteries contain electrolyte, which is composed of lithium salts and organic solvents. Therefore, electrolyte is hazardous and can cause headaches, dizziness, weakness, nausea, and difficulty breathing if inhaled. Centrifugation is commonly used to separate lithium battery electrolyte. However, lithium battery electrolyte contains viscous substances that adhere to the inside of centrifuges, clogging the mesh and slowing down the separation speed. Therefore, it is necessary to recycle the lithium battery electrolyte. Based on the above problems, this application proposes a lithium battery electrolyte recycling device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a lithium battery electrolyte recovery device to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lithium battery electrolyte recycling device includes a centrifugal recycling tank.

A pushing protrusion is fixedly mounted on the outer surface of the centrifugal mesh cylinder, and a rectangular column is fixedly mounted on the lower side wall of the centrifugal mesh cylinder. An elastic component for facilitating the striking of the centrifugal mesh cylinder is provided inside the centrifugal recycling tank. A support plate is fixedly mounted at the rear of the centrifugal recycling tank, and a hydraulic push rod is fixedly mounted on the top of the support plate. A movable plate is fixedly mounted at the output end of the hydraulic push rod, and a tank cover is fixedly mounted on the front side of the movable plate. A material-collecting component is provided on the upper side wall of the tank cover.

[0007] Preferably, the elastic component includes a fixed plate fixedly installed inside the centrifugal recovery tank. A mounting sleeve is fixedly provided on the side of the fixed plate. A limiting ring is fixedly provided at the end of the mounting sleeve away from the fixed plate. A moving rod is slidably provided inside the limiting ring. A limiting plate is fixedly provided at the end of the moving rod located inside the mounting sleeve. The limiting plate is slidably provided inside the mounting sleeve. A spring is fixedly provided on the side of the limiting plate. The spring is fixedly connected to the mounting sleeve. A mounting hole is opened on the end of the moving rod extending outside the mounting sleeve. A metal ball is overlapped inside the mounting hole. A connecting plate is fixedly provided at the extension end of the moving rod. A limiting hole is provided through the surface of the connecting plate. The limiting hole overlaps with the metal ball.

[0008] Preferably, the material handling component includes a mounting ring fixedly installed on the side wall of the box cover. The mounting ring has a sliding groove inside, and an arc-shaped slider is slidably arranged inside the sliding groove. A connecting column is fixedly arranged on the surface of the arc-shaped slider, and a material handling plate is fixedly arranged at the bottom of the connecting column. Both the connecting column and the material handling plate are slidably connected to the centrifugal mesh cylinder. A rectangular groove is opened at the bottom of the material handling plate.

[0009] Preferably, a supporting ring is connected between the bottom of the centrifuge mesh cylinder and the lower side wall of the centrifuge recovery box. The supporting ring is fixedly installed on the lower side wall of the centrifuge recovery box and overlaps with the centrifuge mesh cylinder.

[0010] Preferably, a feed pipe is fixedly installed on the top of the box cover, and the outlet end of the feed pipe passes through the box cover and extends into the interior of the box cover.

[0011] Preferably, the side of the pushing protrusion away from the centrifugal mesh cylinder is an arc-shaped surface, the side of the pushing protrusion is a vertical surface, and the pushing protrusion is made of metal.

[0012] Preferably, a mounting plate is fixedly provided on the surface of the limiting ring, an electromagnet is fixedly provided on the side of the mounting plate, and a metal plate is fixedly provided on the surface of the moving rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the material inside the lithium battery adheres to the inside of the centrifuge mesh and blocks the mesh, the pusher pushes the elastic component to contract. When the pusher separates from the elastic component, the elastic component resets and knocks on the centrifuge mesh, thereby causing the material attached inside the centrifuge mesh to fall off. This prevents the mesh of the centrifuge mesh from being blocked, ensuring that the centrifugal separation effect is not reduced due to mesh blockage. Furthermore, no manual cleaning of the mesh of the centrifuge mesh is required, making the lithium battery electrolyte recovery device more convenient to use. Attached Figure Description

[0022] 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.

[0023] Reference Figure 1-7A lithium battery electrolyte recycling device includes a centrifugal recycling tank 1. A drive motor 2 is fixedly mounted on the bottom of the centrifugal recycling tank 1. A centrifugal mesh cylinder 3 is fixedly mounted on the output end of the drive motor 2. A support ring is connected between the bottom of the centrifugal mesh cylinder 3 and the lower side wall of the centrifugal recycling tank 1. The support ring is fixedly mounted on the lower side wall of the centrifugal recycling tank 1 and overlaps with the centrifugal mesh cylinder 3. The support ring facilitates the support of the centrifugal mesh cylinder 3, preventing the output end of the drive motor 2 from bending under force. A pushing protrusion 4 is fixedly mounted on the outer surface of the centrifugal mesh cylinder 3. The side of the pushing protrusion 4 away from the centrifugal mesh cylinder 3 is an arc-shaped surface, and the side of the pushing protrusion 4 is a vertical surface. The pushing protrusion 4 is made of metal. The curved surface facilitates the movement of the metal ball 13 onto the pushing protrusion 4, while the vertical surface allows the spring 11 to rebound instantly, thus facilitating the striking of the centrifugal mesh cylinder 3. A rectangular column 5 is fixedly installed on the lower side wall of the centrifugal mesh cylinder 3. An elastic component is installed inside the centrifugal recovery box 1 to facilitate striking the centrifugal mesh cylinder 3. The elastic component includes a fixed plate 6 fixedly installed inside the centrifugal recovery box 1. An installation sleeve 7 is fixedly installed on the side of the fixed plate 6. A limit ring 8 is fixedly installed at the end of the installation sleeve 7 away from the fixed plate 6. A moving rod 9 is slidably installed inside the limit ring 8. A limit plate 10 is fixedly installed at the end of the moving rod 9 inside the installation sleeve 7. The limit plate 10 is slidably installed on the installation sleeve 7. Inside, a spring 11 is fixedly installed on the side of the limiting plate 10. The spring 11 is fixedly connected to the mounting sleeve 7. A mounting hole 12 is opened on one end of the moving rod 9 extending outside the mounting sleeve 7. A metal ball 13 is overlapped inside the mounting hole 12. A connecting plate 14 is fixedly installed on the extended end of the moving rod 9. A limiting hole 15 is provided through the surface of the connecting plate 14. The limiting hole 15 overlaps with the metal ball 13. The centrifugal mesh cylinder 3 drives the pushing protrusion 4 to move, so that the metal ball 13 moves along the arc surface of the pushing protrusion 4. This causes the moving rod 9 to push the limiting plate 10 to compress the spring 11. When the metal ball 13 moves out from the arc surface of the pushing protrusion 4, it is compressed by the spring. 11. The limiting plate 10 and the moving rod 9 push the metal ball 13 to strike the centrifugal screen 3, thereby causing the centrifugal screen 3 to vibrate and dislodge the material clogging the mesh of the centrifugal screen 3. A support plate 16 is fixedly installed on the rear side of the centrifugal recovery box 1. A hydraulic push rod 17 is fixedly installed on the top of the support plate 16. A moving plate 18 is fixedly installed at the output end of the hydraulic push rod 17. A box cover 19 is fixedly installed on the front side of the moving plate 18. A feed pipe is fixedly installed on the top of the box cover 19. The discharge end of the feed pipe passes through the box cover 19 and extends into the interior of the box cover 19. The feed pipe facilitates the addition of the crushed lithium battery and electrolyte mixture into the centrifugal screen 3. A material handling component is provided on the upper side wall of the box cover 19.

[0024] Specifically, the material handling assembly includes a mounting ring 20 fixedly installed on the upper side wall of the cover 19. The mounting ring 20 has a sliding groove 21 inside, and an arc-shaped slider 22 is slidably disposed inside the sliding groove 21. A connecting post 23 is fixedly disposed on the surface of the arc-shaped slider 22, and a material handling plate 24 is fixedly disposed at the bottom of the connecting post 23. Both the connecting post 23 and the material handling plate 24 are slidably connected to the centrifuge mesh cylinder 3. A rectangular groove 25 is formed at the bottom of the material handling plate 24. When the cover 19 contacts the centrifuge recovery box 1, the mounting ring 20, through the arc-shaped slider 22 and the connecting post 23, drives the material handling plate 24 into the centrifuge mesh cylinder 3, causing the rectangular post 5 to insert into the rectangular groove 25, thus allowing the mixture to... When the material enters the centrifuge cylinder 3, it falls to the top of the receiving plate 24. As the centrifuge cylinder 3 rotates, the receiving plate 24 rotates through the rectangular column 5 and the rectangular groove 25. The receiving plate 24, through the connecting column 23, drives the arc-shaped slider 22 to slide in the sliding circular groove 21, thus not obstructing the rotation of the centrifuge cylinder 3. When it is necessary to remove the centrifuged material, the hydraulic push rod 17 moves the box cover 19 upward through the moving plate 18, causing the box cover 19 to move the mounting ring 20 upward. The arc-shaped slider 22, through the connecting column 23, moves the receiving plate 24 upward, causing the receiving plate 24 to move the separated material upward, thus facilitating the removal of the separated material from the centrifuge cylinder 3.

[0025] Specifically, a mounting plate is fixedly installed on the surface of the limiting ring 8, and an electromagnet is fixedly installed on the side of the mounting plate. A metal plate is fixedly installed on the surface of the moving rod 9. The electromagnet attracts the metal plate, thereby fixing the position of the moving rod 9. The moving rod 9 fixes the position of the metal ball 13 through the connecting plate 14, so that the centrifugal screen 3 will not be knocked when the mesh is not passively blocked. When the metal ball 13 is at the highest point of the pushing protrusion 4, the metal plate contacts the electromagnet, so that the fixed position of the metal ball 13 will not block the pushing protrusion 4, thus ensuring the normal rotation of the centrifugal screen 3.

[0026] The lithium battery electrolyte recovery device is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0027] In use: The mixture of crushed lithium batteries and electrolyte is added to the centrifugal mesh cylinder 3 through the feed pipe. The centrifugal mesh cylinder 3 is driven to rotate by the drive motor 2, causing the mixture of lithium batteries and electrolyte to be centrifugally separated. The electrolyte after centrifugation is discharged through the drain pipe on the left side of the centrifugal recovery tank 1. When the mesh of the centrifugal mesh cylinder 3 becomes clogged, the electromagnet is de-energized, causing the spring 11 to push the limit plate 10, which in turn moves the moving rod 9 closer to the centrifugal mesh cylinder 3. This causes the moving rod 9 to push the metal ball 13 into contact with the centrifugal mesh cylinder 3. When the centrifugal mesh cylinder 3 rotates centrifugally, it drives the pushing protrusion 4 to move, causing the metal ball 13 to come into contact with the centrifugal mesh cylinder 3. The ball 13 moves along the arc surface of the pushing protrusion 4, causing the metal ball 13 to push the moving rod 9 to retract into the mounting sleeve 7. The moving rod 9 then pushes the limiting plate 10 to compress the spring 11. When the metal ball 13 moves out from the arc surface of the pushing protrusion 4, the spring 11 pushes the limiting plate 10 to move. The limiting plate 10 pushes the metal ball 13 to strike the centrifugal mesh cylinder 3 through the moving rod 9. The striking of the metal ball 13 causes the centrifugal mesh cylinder 3 to vibrate, causing the lithium battery solids that are stuck inside the centrifugal mesh cylinder 3 to fall off, and the lithium battery fixed material to fall off from the mesh of the centrifugal mesh cylinder 3.
