Description

Technical Field

[0001] This utility model relates to the field of battery powder grinding technology, and in particular to an integrated machine for high-efficiency grinding and grading of battery powder. Background Technology

[0002] Battery powder typically refers to the powdered materials generated during battery production, primarily composed of electrode materials such as lithium cobalt oxide, lithium iron phosphate, ternary materials (nickel-cobalt-manganese), or graphite in lithium-ion batteries. These powders are crucial in battery manufacturing, directly affecting battery capacity, cycle life, and safety. With the development of the new energy industry, the recycling of used batteries has become a key focus. Battery powder can be recycled and reused to extract valuable metals or regenerate electrode materials, reducing resource waste and environmental pollution. In recent years, researchers have been exploring more efficient and environmentally friendly battery powder preparation and recycling technologies to promote the sustainable development of the battery industry.

[0003] Currently, during the grinding and processing of battery powder, the fine particles generated easily diffuse into the air, forming metallic dust pollution. Simultaneously, the accompanying high-temperature friction may trigger electrolyte decomposition, releasing toxic gases such as hydrogen fluoride and triphenyl phosphate. These harmful substances are not only highly irritating and corrosive but can also enter the human body through the respiratory tract, causing lung damage, heavy metal poisoning, and other problems. Long-term exposure to this environment can easily lead to occupational respiratory diseases and even pose a risk of cancer to workers. Furthermore, poor ventilation or inadequate protective measures in the workshop will further exacerbate the hazards, seriously threatening the life and health safety of workers.

[0004] Therefore, it is necessary to design a high-efficiency grinding and grading machine for battery powder to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0019] Example: A high-efficiency grinding and grading integrated machine for battery powder, such as... Figure 1 , Figure 2 and Figure 4As shown, the assembly includes a support frame 1, a housing 2, a first motor 3, a splined shaft 4, a guide plate 5, a guide port 6, a lower grinding wheel 7, an upper grinding wheel 8, an activated carbon adsorption box 9, a top cover 10, a protective cover 27, a scraper block 11, a collection box 12, and a handle 13. The housing 2 is screwed onto the upper part of the support frame 1, and a feed port is opened at the top of the housing 2. The first motor 3 is screwed onto the lower part of the support frame 1, and a splined shaft 4 is welded to the output shaft of the first motor 3. A guide plate 5 is welded to the middle of the support frame 1, and a guide port 6 is opened at the front bottom of the guide plate 5. A lower grinding wheel 7 is welded to the middle of the top of the guide plate 5. An upper grinding wheel is rotatably connected to the bottom of the housing 2. 8. Both the upper grinding wheel 8 and the lower grinding wheel 7 are circular structures, which facilitates uniform force and stable rotation, improving grinding efficiency and precision. The bottom of the upper grinding wheel 8 has three feeding holes arranged in a ring. The spline shaft 4 passes through the guide plate 5 and the lower grinding wheel 7 and is welded to the upper grinding wheel 8. The lower part of the box 2 is symmetrically welded with activated carbon adsorption boxes 9. The top of each of the two activated carbon adsorption boxes 9 is covered with a top cover 10. The bottom of the box 2 is connected to and connected with a protective cover 27. The lower outer side of the upper grinding wheel 8 is symmetrically welded with scraping blocks 11. The lower front side of the support frame 1 is slidably connected with a collection box 12. The middle front side of the collection box 12 is welded with a handle 13.

[0020] When this device is needed, first start the first motor 3. The output shaft of the first motor 3 rotates clockwise, driving the splined shaft 4 to rotate. The splined shaft 4 drives the upper grinding wheel 8 to rotate, and the battery powder raw material is added from the feed inlet. The battery powder raw material falls into the upper grinding wheel 8. At the same time, the fine dust and harmful gases generated by the addition of battery powder raw material are adsorbed and purified by the activated carbon adsorption box 9. If the activated carbon inside the activated carbon adsorption box 9 needs to be replaced and maintained regularly, simply open the top cover 10 upwards to complete the activated carbon filling. After the filling is completed, close the top cover 10 downwards. The activated carbon flows into the lower grinding wheel through the three discharge holes of the upper grinding wheel 8. The upper grinding wheel 8 rotates under the drive of the first motor 3, with the lower grinding wheel 7 fixed. An annular grinding gap is formed between the upper grinding wheel 8 and the lower grinding wheel 7. After the battery powder raw material is gradually refined into powder of the required particle size by compression and friction, it is distributed on the guide plate 5. At this time, the protective cover 27 can prevent the ground raw material from floating out and prevent external dust from entering. Then the first motor 3 continues to run, and the battery powder raw material is continuously added to the upper grinding wheel 8 in the device. As a result, the ground battery powder continuously accumulates on the guide plate 5 and overflows, and then flows out from the guide port 6. After the finished powder is ground, the first motor 3 can be turned off.

[0021] When the upper grinding wheel 8 rotates, the two scraper blocks 11 continuously scrape the battery powder that falls on the guide plate 5 into the guide port 6 in its rotation path. The battery powder falls naturally under the influence of gravity and eventually falls into the collection box 12. The collection box 12 can hold a certain amount of ground finished powder. If it is necessary to empty the powder in the collection box 12, the operator should pull the handle 13 forward smoothly to make the collection box 12 leave the support frame 1. After pouring out the powder, push it back to its original position to continue using it.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes support blocks 14, feeding boxes 15, partitions 16, second motors 17, first rotating shafts 18, augers 19, transmission wheels 20, and belts 21. Support blocks 14 are symmetrically welded to the front and back of the top right side of the box body 2. The feeding box 15 is welded between the upper parts of the two support blocks 14. The bottom left side of the feeding box 15 is connected to and communicates with the feed inlet. The partition 16 is welded to the middle of the inside of the feeding box 15. The second motor 17 is screwed on the rear left side of the feeding box 15. The first rotating shafts 18 are symmetrically rotated and connected to the front and back of the middle of the inside of the feeding box 15. Augers 19 are welded to both first rotating shafts 18. The transmission wheels 20 are welded to one end of each of the two first rotating shafts 18 that passes through the feeding box 15. A belt 21 is wound between the two transmission wheels 20. The first rotating shaft 18 located at the rear side of the feeding box 15 passes through the transmission wheels 20 and is welded to the output shaft of the second motor 17.

[0023] Before adding battery powder raw materials to the grinding process, the second motor 17 is started. The output shaft of the second motor 17 rotates clockwise, driving one of the first rotating shafts 18 to rotate, and simultaneously driving the transmission wheel 20 to rotate clockwise. Under the transmission of the belt 21, the other first rotating shaft 18 rotates clockwise through the transmission wheel 20. Thus, the two augers 19 rotate at high speed in the same direction. Then, the operator adds the battery powder raw materials into the feeding box 15. At this time, the support block 14 bears the weight, making the feeding box 15 more stable during the material addition process. Under the action of the partition 16, the battery powder raw materials are separated, allowing the augers 19 to convey and push the battery powder raw materials to the feed port and fall into the upper grinding wheel 8, making it less prone to clogging. If it is necessary to stop adding battery powder raw materials, the second motor 17 can be turned off.

[0024] like Figure 1 and Figure 4As shown, it also includes a third motor 22, a second rotating shaft 23, crushing wheels 24, and gears 25. The third motor 22 is screwed on the left side of the front part of the housing 2. The second rotating shaft 23 is symmetrically connected to the left and right sides of the middle of the housing 2. Crushing wheels 24 are welded on both second rotating shafts 23. The surfaces of the two crushing wheels 24 are provided with raised teeth and sawtooth structures. During rotation, the raised teeth and sawtooth structures can perform strong shearing, tearing, and extrusion on the battery powder raw materials, effectively crushing large pieces of material into smaller particles. Gears 25 are welded to one end of the front side of each of the two second rotating shafts 23, which pass through the housing 2. The two gears 25 mesh with each other. The second rotating shaft 23 located on the left side of the housing 2 passes through the gears 25 and is welded to the output shaft of the third motor 22.

[0025] like Figure 1 As shown, it also includes a protective cover 26. The protective cover 26, which is screwed on the front side of the housing 2, is used to wrap and prevent debris from getting stuck in the two gears 25, and the output shaft of the third motor 22 passes through the protective cover 26.

[0026] When the battery powder material falls into the feed inlet, the third motor 22 is started. The output shaft of the third motor 22 drives the second rotating shaft 23 on the left to rotate clockwise. Because the two gears 25 mesh with each other, the second rotating shaft 23 on the right rotates counterclockwise through the transmission of the gears 25. As a result, the two crushing wheels 24 rotate in opposite directions. Then, the battery powder material falling from directly above the feed inlet is crushed and crushed between the two crushing wheels 24 under the rotation of the crushing wheels 24, and then falls into the upper grinding wheel 8 in the device. Once the battery powder material has been crushed, the third motor 22 can be turned off.
