Description

Technical Field

[0001] This utility model relates to the field of lithium battery recycling technology, specifically to a magnetic separation device for recycling lithium battery electrode materials. Background Technology

[0002] Lithium batteries are mainly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium, are rechargeable, and have a wide range of applications. Lithium metal batteries, as the fifth generation of rechargeable batteries, were introduced in 1996. They are superior in terms of safety, specific capacity, self-discharge rate, and cost-effectiveness, but due to high technical barriers, only companies in a few countries can currently produce them. After the lithium battery reaches the end of its lifespan, it usually needs to be recycled through magnetic separation equipment to achieve effective resource reuse.

[0003] In the field of lithium battery electrode material recycling, traditional magnetic separation devices mostly use a single magnetic separator. The magnetic field area of ​​a single magnetic separator is limited, making it difficult to fully separate magnetic and non-magnetic substances in the electrode material. Furthermore, the material is prone to accumulation and blockage during the feeding process, leading to interruption of the separation process and reducing the overall recycling efficiency. To address this, we propose a magnetic separation device for lithium battery electrode material recycling. Utility Model Content

[0015] This invention provides a magnetic separation device for recycling lithium battery electrode materials. Compared with the prior art, it has the following advantages:

[0016] 1. This lithium battery electrode material recycling magnetic separation device drives magnetic separator one and magnetic separator two to rotate in opposite directions through a rotating component, forming a dual magnetic separation area. When the electrode material enters the separation box from the feed inlet, the material first undergoes preliminary magnetic separation in magnetic separator one, where magnetic substances are adsorbed onto the cylinder wall, while non-magnetic substances continue to fall. Subsequently, the material that has not been fully separated enters the magnetic separation area of ​​magnetic separator two under the action of the guide plate. Through secondary magnetic separation by reverse rotation, the residual magnetic substances are further adsorbed, avoiding the problem of insufficient separation caused by the limited area of ​​a single magnetic separator. At the same time, when the cylinder rotates, the plastic scraper scrapes off the adsorbed magnetic material, which is then discharged directionally under the action of gravity through discharge port one below magnetic separator one and discharge port two below magnetic separator two.

[0017] 2. The magnetic separation device for recycling lithium battery electrode materials includes a vibration component that drives a rotating rod and a cam to rotate via a drive motor. The cam presses against the driven wheel, causing the fixed rod to drive the guide plate to vibrate up and down in the arc-shaped chute. With the spring in the mounting frame resetting, high-frequency vibration is formed, which makes the electrode material falling into the feed port evenly distributed on the guide plate, avoiding the problem of poor material discharge caused by accumulation, and ensuring that the material is continuously and stably conveyed to the surface of the magnetic separator.

[0026] 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.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a magnetic separation device for recycling lithium battery electrode materials, including a separation box 1. The top of the separation box 1 has a feed inlet 2, the middle left side of the separation box 1 has a discharge outlet 4, the middle right side and bottom of the separation box 1 have discharge outlets 3 and 5 respectively, and the upper right and lower left sides of the separation box 1 are respectively provided with magnetic separators 16 and 17. Discharge outlets 3 and 4 are respectively located below magnetic separators 16 and 17, and the magnetic separators 16 and 17 are connected to each other. The second separator cylinder 17 is rotatably installed between the front and rear sides of the separation box 1. The rear shaft ends of the first magnetic separator cylinder 16 and the second magnetic separator cylinder 17 are respectively fixedly connected to the rotating rod 13 and the rotating rod 12. The rear side of the separation box 1 is equipped with a rotating assembly that drives the rotating rod 13 and the rotating rod 12 to rotate in opposite directions. The left and right sides of the interior of the separation box 1 are hinged with guide plates 24. The two sets of guide plates 24 are respectively set at the upper left of the first magnetic separator cylinder 16 and the upper right of the second magnetic separator cylinder 17. The front side of the separation box 1 is equipped with a vibration assembly that drives the two sets of guide plates 24 to vibrate.

[0028] When performing magnetic separation for lithium battery electrode material recycling, the electrode material enters from the feed inlet 2 at the top of the separation box 1 and falls onto the guide plate 24 on the upper left of the magnetic separator 16. The vibration component on the front side of the separation box 1 drives the guide plate 24 to vibrate, dispersing the material evenly before it slides onto the surface of the magnetic separator 16. The magnetic separator 16 is driven to rotate by the rotating component, and its surface magnetic field adsorbs the magnetic electrode material. The non-magnetic material continues to fall and is discharged from the discharge port 3 5 at the bottom of the separation box 1. The material that is not completely adsorbed by the magnetic separator 16 is dispersed again by the guide plate 24 on the upper right of the magnetic separator 27 and slides onto the surface of the magnetic separator 27. The magnetic separator 27 rotates in the opposite direction to the magnetic separator 16, further adsorbing the remaining magnetic material. The non-magnetic material is also discharged from the discharge port 3 5. The magnetic material adsorbed on the surfaces of the magnetic separator 16 and the magnetic separator 27 rotates with the cylinder and is discharged from the discharge port 1 3 and the discharge port 2 4 at the bottom, completing the separation.

[0029] The rotating assembly includes mounting cover 9 and mounting cover 10. Both mounting cover 9 and mounting cover 10 are fixedly connected to the rear side of the separation box 1. The rear ends of rotating rod 13 and rotating rod 12 are respectively rotatably mounted on mounting cover 9 and mounting cover 10. A worm gear 19 is fixedly sleeved on rotating rod 12. A worm 20 is rotatably mounted between the left and right sides of the bottom of mounting cover 10. A drive motor 11 is fixedly mounted on the rear side of the separation box 1. The output shaft end of drive motor 11 is fixedly connected to the left end of worm 20. A rotating rod 14 is also rotatably mounted on mounting cover 9. The front end of rotating rod 14 is rotatably mounted on the rear side of the separation box 1. A synchronous pulley 21 is fixedly sleeved on both rotating rod 12 and rotating rod 14. A synchronous belt 15 is tensioned and sleeved between the two sets of synchronous pulleys 21. Gears 18 are also fixedly sleeved on both rotating rod 13 and rotating rod 14. The two sets of gears 18 mesh with each other.

[0030] When the rotating assembly is working, after the drive motor 21 starts, its output shaft drives the worm 20 to rotate. The worm 20 meshes with the worm wheel 19 on the rotating rod 12, driving the rotating rod 12 to rotate. The rotating rod 12 drives the synchronous pulley 21 on the rotating rod 3 14 to rotate via the synchronous belt 15 through the fixedly sleeved synchronous pulley 21, causing the rotating rod 3 14 to rotate. The gear 18 on the rotating rod 3 14 meshes with the gear 18 on the rotating rod 2 13, thereby driving the rotating rod 2 13 to rotate in the opposite direction, realizing the opposite rotation of the rotating rod 2 13 and the rotating rod 12, and thus driving the magnetic separator 1 16 and the magnetic separator 2 17 to rotate in the opposite direction.

[0031] The vibration assembly includes a mounting box 7, which is fixedly connected to the front of the separation box 1. Two sets of guide plates 24 are each fixedly connected to a fixing rod 34 on their front sides. Arc-shaped grooves 33 are respectively opened through the upper and lower front sides of the separation box 1. The two sets of fixing rods 34 extend out of the front of the separation box 1 through the two sets of arc-shaped grooves 33. Mounting frames 29 are also fixedly connected to the upper and lower front sides of the separation box 1. Both sets of mounting frames 29 are located inside the mounting box 7. The front parts of the two sets of fixing rods 34 are respectively located inside the two sets of mounting frames 29. Springs 35 are provided on the upper and lower sides of the interior of the mounting frames 29, and the two sets of springs 35 abut against the upper and lower sides of the fixing rods 34 respectively. A drive mechanism is mounted on the mounting box 7.

[0032] The drive mechanism includes a drive motor 8, which is fixedly mounted on the front side of the mounting box 7. Rotating rods 27 are rotatably mounted on both the upper and lower sides of the mounting box 7. The rear ends of the two sets of rotating rods 27 are rotatably mounted on the front side of the separation box 1. Cams 28 are fixedly sleeved on both sets of rotating rods 27. Driven wheels 30 are fixedly sleeved on the front ends of both sets of fixed rods 34. The output shaft end of the drive motor 8 is fixedly connected to the front end of one set of rotating rods 27. Pulleys 31 are also fixedly sleeved on both sets of rotating rods 27. A belt 32 is tensioned and sleeved between the two sets of pulleys 31.

[0033] When the vibration assembly is working, after the drive motor 8 starts, its output shaft drives one set of rotating rods 27 to rotate. This set of rotating rods 27 drives another set of rotating rods 27 to rotate synchronously through pulley 31 and belt 32. The cams 28 on the two sets of rotating rods 27 rotate accordingly. When the protruding part of the cam 28 presses against the driven wheel 30, the fixed rod 34 drives the guide plate 24 to move upward along the arc-shaped slide 33, compressing the spring 35 in the mounting frame 29. When the protruding part of the cam 28 rotates away from the driven wheel 30, the spring 35 resets and pushes the fixed rod 34 downward, causing the guide plate 24 to fall back along the arc-shaped slide 33, thereby realizing the reciprocating vibration of the guide plate 24.

[0034] Scrapers 25 are fixedly installed on both the left and right sides of the interior of the separation box 1. Two sets of scrapers 25 are respectively located in the middle right side of magnetic separator 16 and the middle left side of magnetic separator 27. The sides of the two sets of scrapers 25 that are close to each other abut against the outer surfaces of magnetic separator 16 and magnetic separator 27, respectively. When magnetic separator 16 and magnetic separator 27 rotate, the scrapers 25 continuously scrape off the magnetic material adsorbed on the cylinder wall, causing the material to fall off the surface of magnetic separator 16 and magnetic separator 27.

[0035] Inside the separator 1, baffle plate 1 22 and baffle plate 23 are fixedly connected to the top and left sides respectively. The bottom of baffle plate 1 22 and baffle plate 23 abut against the top outer surface of magnetic separator 16 and magnetic separator 27 respectively. The bottom of baffle plate 1 22 and baffle plate 23 abut against the top outer surface of magnetic separator. When the material slides from the guide plate 24 to the magnetic separator, the baffle plate restricts the movement trajectory of the material, prevents the material from splashing or deviating from the magnetic separation area, and ensures that the material evenly covers the surface of the magnetic separator for full magnetic separation.

[0036] The scraper 25 is made of plastic. Utilizing the wear resistance and low coefficient of friction of the plastic material, it can effectively clean the residual substances when scraping the material on the surface of magnetic separator 16 and magnetic separator 27, while avoiding scratches on the outer surface of magnetic separator 16 and magnetic separator 27.

[0037] Dustproof sleeves 36 are fitted on both sets of fixed rods 34. The front side of the dustproof sleeves 36 is fixedly connected to the inner wall of the separation box 1. When the guide plate 24 vibrates through the fixed rods 34, the dustproof sleeves 36 extend and retract with the movement of the fixed rods 34, preventing the dust inside the separation box 1 from leaking out through the arc-shaped sliding groove 33, thus playing a role in sealing and preventing dust.

[0038] An air outlet 26 is provided on the front side of the separation box 1. An air outlet pipe is fixedly connected to the air outlet 26. When the device is running, the air outlet pipe can discharge and collect the air and dust in the separation box 1, maintain the air circulation in the box, avoid dust accumulation and affect the magnetic separation effect, and at the same time assist the equipment in heat dissipation to ensure the stable operation of the device.

[0039] Brake casters 6 are installed at the four corners of the bottom of the separation box 1, and the brake casters 6 at the bottom of the separation box 1 support the overall movement of the device.

[0040] Working principle: When performing magnetic separation for the recycling of lithium battery electrode materials, the drive motor 8 is started first. Its output shaft drives one set of rotating rods 27 to rotate. This set of rotating rods 27 drives another set of rotating rods 27 to rotate synchronously through pulley 31 and belt 32. The cams 28 on the two sets of rotating rods 27 rotate accordingly. When the protruding part of the cam 28 presses against the driven wheel 30, the fixed rod 34 drives the guide plate 24 to move upward along the arc-shaped slide 33, compressing the spring 35 in the mounting frame 29. When the protruding part of the cam 28 moves away from the driven wheel 30, the spring 35 resets and pushes the fixed rod 34 downward, causing the guide plate 24 to fall back along the arc-shaped slide 33, thereby realizing the reciprocating vibration of the two sets of guide plates 24.

[0041] Simultaneously, drive motor 21 is started, and its output shaft drives worm 20 to rotate. Worm 20 meshes with worm wheel 19 on rotating rod 12, driving rotating rod 12 to rotate. Rotating rod 12 drives synchronous pulley 21 on rotating rod 31 to rotate via synchronous belt 15 through fixedly sleeved synchronous pulley 21, causing rotating rod 314 to rotate. Gear 18 on rotating rod 314 meshes with gear 18 on rotating rod 23, thereby driving rotating rod 23 to rotate in the opposite direction, realizing the opposite rotation of rotating rod 213 and rotating rod 12, and further driving magnetic separator 16 and magnetic separator 27 to rotate in the opposite direction.

[0042] Next, the electrode material enters from the feed port 2 at the top of the separation box 1 and falls onto the guide plate 24 on the upper left of the magnetic separator 16. The vibration of the guide plate 24 disperses the material evenly and it slides onto the surface of the magnetic separator 16. During the rotation of the magnetic separator 16, the magnetic field on its surface attracts the magnetic electrode material, while the non-magnetic material continues to fall and is discharged from the discharge port 3 5 at the bottom of the separation box 1. The material that is not completely attracted by the magnetic separator 16 is dispersed again by the vibration of the guide plate 24 on the upper right of the magnetic separator 27 and slides onto the surface of the magnetic separator 27, where the remaining magnetic material is further attracted. The non-magnetic material is also discharged from the discharge port 3 5.

[0043] The magnetic material adsorbed on the surfaces of magnetic separator 16 and magnetic separator 27 rotates with the cylinder. The scrapers 25 on the left and right sides inside the separation box 1 respectively abut against the outer surfaces of magnetic separator 16 and magnetic separator 27. When magnetic separator 16 and magnetic separator 27 rotate, the scrapers 25 continuously scrape off the magnetic material adsorbed on the cylinder wall, causing the material to fall off the surfaces of magnetic separator 16 and magnetic separator 27 and be discharged from the discharge port 3 and discharge port 4 below, thus completing the separation.
