Description

Technical Field

[0001] This utility model relates to the field of lithium battery recycling technology, and in particular to an electrode material separation device for lithium battery dismantling. Background Technology

[0002] With the widespread adoption of new energy vehicles and portable electronic devices, the use of lithium batteries has increased significantly. However, lithium batteries have a limited lifespan, and improper disposal of retired lithium batteries not only wastes resources but also pollutes the environment. Separation of electrode materials is one of the key steps in the recycling process of lithium batteries.

[0003] As shown in CN211755956U, a magnetic separation device for recycling waste lithium battery electrode materials includes a box body. Three inclined plates and three electromagnets are equidistantly installed on the top of the box body. Through the coordinated use of cams, connecting rods, inclined plates, and electromagnets, multiple inclined plates and electromagnets can effectively adsorb magnetic materials, resulting in relatively thorough processing. However, this device requires the crushed electrode material to be poured into the box body for magnetic separation. Since the crushed electrode material is difficult to sized, the device can only perform magnetic separation on the electrode material itself; subsequent screening of the separated electrode material is still necessary. This cumbersome operation leads to low separation efficiency.

[0004] Therefore, a lithium battery dismantling electrode material separation device has been developed that can screen and then magnetically separate broken electrode materials, reducing the processing steps of electrode material separation and improving separation efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing electrode material separation devices for lithium battery dismantling, which can only perform magnetic separation of electrode materials and still require subsequent screening of the separated electrode materials, resulting in a cumbersome operation and low separation efficiency, this utility model provides an electrode material separation device for lithium battery dismantling that can screen the crushed electrode materials before magnetic separation, thereby reducing the processing steps for electrode material separation and improving separation efficiency.

[0006] Technical Solution: An electrode material separation device for lithium battery dismantling includes a shell, a feed inlet, a stirring rod, a motor, a flat belt, a pulley, a discharge outlet, a discharge plate, a filter assembly, and a magnetic separation assembly. The feed inlet is connected to the upper left rear part of the shell, and the stirring rod is rotatably connected to the lower part of the feed inlet. The motor is connected to the right side of the middle part of the shell, and two pulleys are connected to the motor output shaft. A pulley is also connected to the right side of the stirring rod. A flat belt is wound between the pulley on the stirring rod and the pulley on the right side of the motor output shaft. Discharge outlets are connected to the lower left and right sides of the shell, and a discharge plate is connected to the lower rear side of the shell. A filter assembly capable of filtering electrode materials is provided on the right side of the shell, and a magnetic separation assembly capable of magnetic separation is provided on the lower inner part of the outer shell.

[0007] As an improvement to the above scheme, the feed inlet is a conical structure.

[0008] As an improvement to the above solution, the filter assembly includes a spring, a filter screen, a protrusion, and a striking block. The filter screen is slidably connected to the top of the housing. Multiple springs connect the filter screen to the housing. The filter screen is located below the feed inlet. A protrusion is connected to the lower right side of the filter screen. A striking block is also connected to the motor output shaft. The striking block passes through the housing and is pressed against the protrusion.

[0009] As an improvement to the above scheme, the bump is a triangular structure.

[0010] As an improvement to the above solution, the filter screen has an inclined structure.

[0011] As an improvement to the above solution, it also includes a magnetic cylinder, a feeding plate, and a scraper. The magnetic cylinder is rotatably connected to the lower part of the outer shell. The magnetic cylinder passes through the baffle inside the outer shell. A pulley is also connected to the right side of the magnetic cylinder. A flat belt is connected between the pulley on the magnetic cylinder and the pulley on the left side of the motor output shaft. Two feeding plates are connected to the rear side of the inner shell. Two scrapers are connected to the front side of the lower part of the inner shell. The scrapers are in contact with the adjacent magnetic cylinder.

[0012] This invention achieves the effect of separating electrode materials in lithium battery dismantling by breaking up the broken electrode materials, screening them through a filter screen, and then magnetically separating the screened electrode materials through a magnetic cylinder. This reduces the processing steps of electrode material separation and improves the separation efficiency. Attached Figure Description

[0019] 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.

[0020] An electrode material separation device for lithium battery disassembly, such as Figures 1-5 As shown, the device includes a housing 1, a feed inlet 2, a stirring rod 21, a motor 3, a flat belt 4, a pulley 5, a discharge port 6, a discharge plate 7, a filter assembly, and a magnetic separation assembly. The feed inlet 2 is connected to the upper left rear part of the housing 1. The feed inlet 2 has a conical structure to facilitate feeding. The stirring rod 21 is rotatably connected to the lower part of the feed inlet 2. The motor 3 is connected to the right side of the middle part of the housing 1. Two pulleys 5 are connected to the output shaft of the motor 3. A pulley 5 is also connected to the right side of the stirring rod 21. A flat belt 4 is wound between the pulley 5 on the stirring rod 21 and the pulley 5 on the right side of the output shaft of the motor 3. The discharge ports 6 are connected to the lower left and right sides of the housing 1. The discharge plate 7 is connected to the lower rear side of the housing 1. The right side of the housing 1 is equipped with a filter assembly that can filter the electrode material. The lower inner part of the housing 1 is equipped with a magnetic separation assembly that can perform magnetic separation.

[0021] like Figure 2 and Figure 3 As shown, the filter assembly includes a spring 8, a filter screen 9, a protrusion 10, and a striking block 11. The filter screen 9 is slidably connected to the top of the housing 1. Multiple springs 8 are connected between the filter screen 9 and the housing 1. The filter screen 9 is located below the feed inlet 2. A protrusion 10 is connected to the lower right side of the filter screen 9. The protrusion 10 has a triangular structure. The striking block 11 is also connected to the output shaft of the motor 3. The striking block 11 passes through the housing 1 and is pressed against the protrusion 10.

[0022] like Figure 4 and Figure 5As shown, it also includes a magnetic cylinder 12, a feeding plate 13, and a scraper 14. The magnetic cylinder 12 is rotatably connected to the lower part of the outer shell 1. The magnetic cylinder 12 passes through the baffle inside the outer shell 1. A pulley 5 is also connected to the right side of the magnetic cylinder 12. A flat belt 4 is connected between the pulley 5 on the magnetic cylinder 12 and the pulley 5 on the left side of the output shaft of the motor 3. Two feeding plates 13 are connected to the rear side of the inner shell 1. Two scrapers 14 are connected to the front side of the lower part of the inner shell 1. The scrapers 14 are in contact with the adjacent magnetic cylinder 12.

[0023] When using this invention, first place the outer casing 1 in the separation area of ​​the lithium battery electrode material, then pour the crushed electrode material into the feed inlet 2. Simultaneously, start the motor 3, causing the pulley 5 and the striking block 11 to rotate. Through the transmission action of the pulley 5, the stirring rod 21 rotates. As the stirring rod 21 rotates, the electrode material is stirred and dispersed evenly before falling into the filter screen 9. When the striking block 11 rotates, it squeezes the protrusion 10, causing it to move. Under the action of the spring 8, the filter screen 9 vibrates up and down, sieving the electrode material. Larger electrode materials fall to the right side of the outer casing 1, while smaller ones... Small electrode materials are screened and fall to the left side of the outer shell 1. Then, the electrode materials slide down the feed plate 13 onto the magnetic cylinder 12. The magnetic materials in the electrodes are attracted to the magnetic cylinder 12, while the non-magnetic materials are discharged and collected from the discharge plate 7. The magnetic materials are scraped off by the scraper 14 during the rotation of the magnetic cylinder 12 and discharged and collected from the discharge port 6. The magnetic and non-magnetic materials collected on the left can be directly recycled, while the magnetic and non-magnetic materials on the right need to be crushed again. This process can screen the crushed electrode materials and then perform magnetic separation, reducing the processing steps for electrode material separation and improving separation efficiency.
