Description

Technical Field

[0001] This utility model relates to the field of waste lithium-ion battery recycling, and in particular to a waste lithium-ion battery fragment sorting device. Background Technology

[0002] With the development of technology, the demand for lithium-ion batteries is growing rapidly, resulting in a large amount of waste lithium-ion batteries. The iron casing, as well as the copper and aluminum metals inside, of these waste lithium-ion batteries are important resources with extremely high recycling value. Therefore, it is necessary to recycle waste lithium-ion batteries. The most important aspect of waste lithium battery recycling is physical sorting to recover the metal resources. Traditional sorting methods struggle to effectively separate the various metal materials and black powder inside the batteries. Therefore, we propose a waste lithium-ion battery fragment sorting device. Utility Model Content

[0003] This invention proposes a waste lithium-ion battery fragment sorting device, which solves the existing problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a waste lithium-ion battery fragment sorting device, comprising a workbench, a first motor installed on the outside of the workbench, and a first transmission shaft connected to the output end of the first motor, a roller sleeved on the outside of the first transmission shaft, a conveyor belt arranged on the outside of the roller, a magnetic block arranged on one side of the discharge end inside the conveyor belt, a scraper arranged in the middle of the bottom end of the conveyor belt, a waste bin installed at the bottom of the scraper, first baffles arranged on both sides of the conveyor belt, and a brush connected to the inner side of the first baffles, a sloping guide plate arranged on one side of the conveyor belt in the direction of movement, and a vibrating screen mechanism arranged at the bottom of the guide plate.

[0005] Preferably, the vibrating screen mechanism includes a base, and a second motor is installed on one side of the base. The output end of the second motor is connected to a second drive shaft, and a connecting block is connected to the other side of the second drive shaft.

[0006] Preferably, the connecting block has a connecting part, and the connecting part is connected to a first connecting shaft. The other side of the first connecting shaft is connected to a first swing rod, and the other end of the first swing rod is connected to a second connecting shaft. One side of the second connecting shaft is connected to a screen frame.

[0007] Preferably, the base is provided with two sets of second swing rods on its outer side, and the two sets of second swing rods have different lengths, with the other end of the two sets of second swing rods connected to the screen frame.

[0008] Preferably, the top of the screen frame is provided with a second baffle, the screen frame has screen holes arranged in a linear pattern inside, the bottom of the screen frame is connected to a powder box, and the powder box has a discharge port on one side.

[0009] Preferably, a feeding platform is provided on one side of the top of the workbench.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. By adopting a sloping design at the bottom of the feeding platform, waste materials can enter the conveyor belt more effectively, and first baffles are set on both sides of the conveyor belt to prevent material spillage and improve work cleanliness.

[0012] 2. By installing magnetic blocks on one side of the discharge end inside the conveyor belt, the iron shell is attracted to the material when it reaches the magnetic blocks. Since the magnetic blocks are only positioned halfway inside the conveyor belt, and with the help of scrapers below the conveyor belt demagnetizing the iron shell, it is collected into the waste bin. A vibrating screen mechanism further separates the copper and aluminum metals from the waste lithium-ion batteries from the black powder. The black powder passes through the vibrating screen and enters the powder bin below, completing the removal of the black powder. The combined use of these two mechanisms achieves a better separation effect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-7 This utility model provides a technical solution: a waste lithium-ion battery fragment sorting device, including a workbench 1, a first motor 2 installed on the outside of the workbench 1, and a first transmission shaft 3 connected to the output end of the first motor 2, a roller 6 sleeved on the outside of the first transmission shaft 3, a conveyor belt 4 arranged on the outside of the roller 6, a magnetic block 5 arranged on one side of the discharge end inside the conveyor belt 4, and another roller 6 sleeved on the inside of the magnetic block 5. The roller 6 is non-magnetic, and the magnetic block 5 does not affect the rotation of the roller 6. A scraper 10 is arranged in the middle of the bottom end of the conveyor belt 4, a waste bin 9 is installed at the bottom of the scraper 10, first baffles 7 are arranged on both sides of the conveyor belt 4, and a brush 8 is connected to the inside of the first baffles 7. A sloping guide plate 11 is arranged on one side of the conveyor belt 4 in the direction of movement, and a vibrating screen mechanism is arranged at the bottom of the guide plate 11. A feeding platform 25 is arranged on one side of the top of the workbench 1.

[0023] In practice, when screening out the iron casing of waste lithium-ion batteries, the material is first manually poured into the feeding platform 25. The bottom of the feeding platform 25 is designed with a ramp to allow the material to move more easily to the conveyor belt 4. The rotation of the first motor 2 drives the first drive shaft 3 to rotate, which in turn drives the roller 6 to rotate, thus enabling the conveyor belt 4 to operate. First baffles 7 are installed on both sides and the top of the conveyor belt 4, and the first baffles 7 fit into one side of the feeding platform 25, preventing the material from spilling onto the ground and the black powder from flying around during the pouring process, thus ensuring the cleanliness of the working area. As the material moves forward, the brush 8 inside the first baffle 7 removes a small amount of black powder adhering to the top of the iron sheet shell. When the material moves to the top of the magnetic block 5, the magnetic block 5 attracts the iron sheet shell. When it reaches one side of the conveyor belt 4, the copper and aluminum metals and black powder enter the vibrating screen mechanism, while the iron sheet shell enters the bottom of the conveyor belt 4. When it reaches the bottom, because the magnetic block 5 is only set at half of the conveyor belt 4, the iron sheet shell is demagnetized. The scraper 10 at the bottom scrapes off the iron sheet shell, allowing it to enter the waste bin 9. Through the above operations, the separation of the iron sheet shell can be facilitated.

[0024] Please refer to Figures 4-7 The vibrating screen mechanism includes a base 12, and a second motor 13 is installed on one side of the base 12. The output end of the second motor 13 is connected to a second drive shaft 14, and the other side of the second drive shaft 14 is connected to a connecting block 15. A connecting part is provided in the connecting block 15, and a first connecting shaft 16 is connected to the connecting part. A first swing rod 17 is connected to the other side of the first connecting shaft 16, and a second connecting shaft 18 is connected to the other end of the first swing rod 17. A screen frame 20 is connected to one side of the second connecting shaft 18. Two sets of second swing rods 19 are provided on the outside of the base 12, and the two sets of second swing rods 19 have different lengths. The other ends of the two sets of second swing rods 19 are connected to the screen frame 20. A second baffle 22 is provided on the top of the screen frame 20. The screen frame 20 has screen holes 21 arranged in a linear pattern inside. A powder box 23 is connected to the bottom of the screen frame 20, and a discharge port 24 is provided on one side of the powder box 23.

[0025] In specific implementation, when separating copper, aluminum, and black powder, the material enters the screen frame 20 through the guide plate 11 set on one side of the conveyor belt 4. The guide plate 11 has a semi-sloping structure, allowing the material to enter the screen frame 20 smoothly. The rotation of the second motor 13 drives the rotation of the second transmission shaft 14, which in turn drives the connecting block 15 to rotate. The rotation of the connecting block 15 drives the first swing rod 17 to vibrate. The movement of the first swing rod 17 drives the screen frame 20 to move. Two sets of second swing rods 19 are connected to both sides of the screen frame 20. The second swing rod 19 has a different length, which allows the screen frame 20 to be placed at an angle, enabling better material movement. The black powder, through the swinging motion, enters the powder box 23 via the screen holes 21 inside the screen frame 20. A second baffle 22 is installed at the top of the screen frame 20 to prevent material from flying out during vibrating screen operation. A discharge port 24 is opened on one side of the powder box 23. Because the screen frame 20 is placed at an angle, after multiple vibrating screens, a lot of black powder may accumulate on one side of the powder box 23, causing it to overflow from the bellows. The discharge port 24 can be connected to a dust bag for better collection of the black powder. Through the above operations, the separation of copper and aluminum metals from black powder can be facilitated.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
