Description

Technical Field

[0001] The utility model relates to the technical field of graphite processing, in particular to a demagnetizing device for graphite anode materials. Background Art

[0002] Graphite anode material is a common anode material for lithium-ion batteries and is usually used in modern batteries. It is composed of graphite particles and has excellent electrical conductivity and cycle stability. It is one of the widely used anode materials in lithium-ion batteries. During the preparation process of graphite materials, they will be contaminated by magnetic impurities from production equipment or raw materials. These impurities may affect the conductive performance and cycle stability of graphite. Therefore, by treating graphite with a demagnetizing device, the magnetic impurities therein can be effectively removed, and the purity and quality of graphite can be improved.

[0003] When an existing demagnetizing device for graphite anode materials is in use, a vibration motor is installed at the bottom of the magnetic sieve to help screen raw materials and increase the demagnetizing efficiency. However, in this way, the magnetic sieve plate cannot be cleaned during use. The magnetic sieve plate is one of the key components of the demagnetizing device. If it cannot be cleaned, a large amount of magnetic impurities will accumulate on the magnetic sieve plate. This will reduce the efficiency of the demagnetizing device, affect the removal effect of magnetic impurities in the graphite anode material, lead to a decline in the performance of the demagnetizing device, and increase the maintenance cost of the equipment. The impurities accumulated over a long time will cause device failures or damages, requiring more frequent repairs or component replacements, increasing production costs.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the present utility model: A demagnetization device for graphite anode materials includes a box body 1. An installation frame 22 is fixedly connected inside the box body 1. A cylinder 26 is fixedly connected inside the installation frame 22. The output end of the cylinder 26 is fixedly connected with a pushing block 23. The upper part of the pushing block 23 is fixedly connected with a magnetic sieve plate 17. The magnetic sieve plate 17 is slidably connected inside the box body 1. Both sides of the bottom of the magnetic sieve plate 17 are fixedly connected with a limiting component. The limiting component includes a slide block 21. The slide block 21 is fixedly connected to the bottom of the magnetic sieve plate 17. The slide block 21 is slidably connected to the outside of a slide rod 20. The slide rod 20 is fixedly connected to both sides inside the box body 1. One side inside the box body 1 is fixedly connected with a fixed frame 18. Buffer springs 19 are fixedly connected inside the fixed frame 18. Slide rods 20 are fixedly connected inside the buffer springs 19. The other end of the slide rod 20 is fixedly connected with the magnetic sieve plate 17.

[0024] The crushed material will first pass through the magnetic sieve plate 17 for fine screening. Due to its unique magnetic properties, the magnetic sieve plate 17 can effectively adsorb magnetic substances in the material. Start the cylinder 26, and the output end of the cylinder 26 can push the push block 23 to move. During the movement of the push block 23, it will drive the magnetic sieve plate 17 to move together. During the movement of the magnetic sieve plate 17, it will drive the slider 21 to slide outside the slide bar 20. Under the action of the slider 21, the magnetic sieve plate 17 will move to the right and at the same time squeeze or stretch the buffer spring 19, making the movement of the magnetic sieve plate 17 smoother. When the magnetic sieve plate 17 completely moves out of the interior of the box body 1, the operator can easily clean the magnetic sieve plate 17. After cleaning, the magnetic sieve plate 17 is pushed back to its original position through the cooperation of the cylinder 26 and the push block 23 to continue the next round of screening work.

[0025] Refer to Figure 1 and Figure 3 As shown in FIGS. 1 and 2, a base plate 3 is fixedly connected to the left part of the box body 1. A motor 4 is fixedly connected to the upper part of the base plate 3. The output end of the motor 4 is fixedly connected to a driving gear 5. A driven gear 6 is meshed and connected to one side of the driving gear 5. Rotating rods 7 are fixedly connected to the interiors of the driving gear 5 and the driven gear 6. Crushing blades 8 are fixedly connected to the exteriors of the rotating rods 7. A feed hopper 2 is arranged on the upper part of the box body 1. A discharge port is formed in the bottom of the box body 1. A fixed cover 9 is fixedly connected to the interior of the box body 1. The crushing blades 8 are rotatably connected to the interior of the fixed cover 9. A support frame 24 is fixedly connected to the bottom of the box body 1. A collection box 25 is arranged in the interior of the support frame 24.

[0026] Precisely place the material to be processed into the interior of the box body 1 through the feed hopper 2. Start the motor 4. The output end of the motor 4 is closely connected to the driving gear 5. When the motor 4 is started, it will drive the driving gear 5 to start rotating. The meshed connection between the driving gear 5 and the driven gear 6 realizes the transmission of power. With the coordinated rotation of the driving gear 5 and the driven gear 6, the rotating rod 7 also starts to rotate accordingly. The rotation of the rotating rod 7 drives the crushing blades 8 to start rotating. Under the high-speed rotation of the crushing blades 8, the material is quickly crushed into the required particle size. During the screening process, the qualified material without magnetic substances will smoothly discharge through the discharge port and then be collected into the interior of the collection box 25 for unified collection.

[0027] Refer to Figure 2 and Figure 3, a placement plate 10 is fixedly connected to the rear of the box body 1. An air blower 11 is fixedly connected to the upper part of the placement plate 10. The output end of the air blower 11 is fixedly connected to a conveying hose 12. The other end of the conveying hose 12 is fixedly connected to a fixed pipe 13. Air outlet pipes 14 are arranged on one side of the fixed pipe 13. A water storage tank 15 is arranged on the upper part of the placement plate 10. A heating pipe 16 is arranged inside the water storage tank 15. The conveying hose 12 is inserted into the inside of the water storage tank 15.

[0028] Start the air blower 11, and suck the air in the surrounding environment through its strong suction force. The air blower 11 ensures that air can continuously enter the conveying hose 12. Under the guidance of the conveying hose 12, the air is conveyed into the inside of the water storage tank 15. There is an appropriate amount of water inside the water storage tank 15. This water is heated under the action of the heating pipe 16. The heating pipe 16 can quickly and evenly heat the water in the water storage tank 15 to reach the set temperature. As the water temperature in the water storage tank 15 rises, the heated water begins to heat the air inside the conveying hose 12. Through the action of heat conduction and heat convection, the temperature of the air gradually rises and finally becomes hot air. After the hot air is generated, it will continue to flow in the conveying hose 12 and finally enter the fixed pipe 13. Finally, the hot air is discharged through the air outlet pipe 14 to perform a comprehensive drying treatment on the material.

[0029] Working principle: First, the material is added into the interior of the box body 1 through the feed hopper 2. The motor 4 is started, and the output end of the motor 4 drives the driving gear 5 to rotate. The rotation of the driving gear 5 drives the engaged driven gear 6 to rotate. The rotation of the driving gear 5 and the driven gear 6 drives the rotating rod 7 to rotate. The rotation of the rotating rod 7 drives the crushing blade 8 to rotate to crush the material. At the same time, the blower 11 is started to extract air, and under the action of the conveying hose 12, the air is conveyed. When the air is conveyed into the interior of the water storage tank 15, there is water and a heating pipe 16 inside the water storage tank 15. The heating pipe 16 heats the water, and the heated water heats the air inside the conveying hose 12, making the air inside the conveying hose 12 become hot air. Then the hot air is conveyed to the fixed pipe 13 and finally discharged through the air outlet pipe 14 to dry the material. Thus, it is realized that the material can be effectively crushed and dried, the pores and moisture in the material can be reduced, making the graphite anode material more stable, which helps to improve the cycle life and safety of the battery. The crushed material is screened through the magnetic sieve plate 17. The magnetic sieve plate 17 adsorbs magnetic substances. The qualified material is discharged through the discharge port into the interior of the collection box 25 for collection. The magnetic substances remain on the upper part of the magnetic sieve plate 17. The cylinder 26 is started, and the output end of the cylinder 26 pushes the push block 23 to move. When the push block 23 moves, it drives the magnetic sieve plate 17 to move. When the magnetic sieve plate 17 moves, it drives the slider 21 to slide outside the sliding rod 20. Under the action of the slider 21, the magnetic sieve plate 17 moves to the right. When the magnetic sieve plate 17 moves, it squeezes or stretches the buffer spring 19. After the magnetic sieve plate 17 moves out of the interior of the box body 1, the magnetic sieve plate 17 can be cleaned. Thus, it is realized that it is convenient to clean the magnetic sieve plate 17, ensuring that the demagnetization device is always in an efficient operation state, guaranteeing the continuity and stability of the production process, and reducing the frequency of equipment replacement and maintenance.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
