Description

Technical Field

[0001] This application relates to the technical field of graphite particle production, and particularly relates to a grinding device for graphite particle production. Background Art

[0002] In the production process of graphite particles, the grinding of raw materials is a key process, which directly affects the particle size, uniformity and quality of the final product. In actual operation, the graphite grinding method mostly adopts the rolling grinding technology. Although this technology can achieve the crushing and refinement of graphite to a certain extent, there are still some problems in actual application.

[0003] Rolling grinding usually squeezes and crushes graphite by using rolling parts. However, during the rolling process, the graphite raw materials are prone to stick tightly under the strong extrusion force, forming a dense layered structure. This structure makes it difficult for the inner graphite particles to be directly affected by the external grinding force, resulting in insufficient grinding of the inner graphite particles and affecting the overall quality and particle size distribution of the product.

[0004] Secondly, the rolling grinding often has the problem of grinding dead corners. Due to the shape of the rolling parts and the structure limitation of the grinding cavity, the graphite raw materials are prone to accumulate and form dead corners in the cavity during the grinding process. The graphite particles in these areas are difficult to be ground, resulting in uneven particle size distribution of the product and affecting the grinding effect of graphite.

[0005] In view of the above problems, a grinding device for graphite particle production is now designed. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0025] The embodiments of the present application provide a grinding device for producing graphite particles, which can solve the problems in the related art that when graphite raw materials are rolled and ground, the inner-layer graphite particles are not sufficiently ground, there are grinding dead corners, resulting in uneven grinding of the graphite raw materials.

[0026] Please refer to Figures 1-3 , a grinding device for producing graphite particles includes; a frame body 1;

[0027] A flipping mechanism 2, which includes a rotating part 21 and a grinding cylinder 22, the grinding cylinder 22 is rotatably arranged on the frame body 1, and the rotating part 21 is connected to the grinding cylinder 22 and is used to drive the grinding cylinder 22 to rotate;

[0028] A grinding mechanism 3, which includes a group of polishing rollers 31 arranged oppositely inside the grinding cylinder 22, a driving part 32 arranged on the grinding cylinder 22, the driving part 32 is used to drive the polishing rollers 31, baffle plates 33 arranged oppositely inside the grinding cylinder 22, the two baffle plates 33 are located on both sides of the polishing rollers 31, and a filter sheet 34 located at the bottom of the polishing rollers 31 is arranged between the bottoms of the two baffle plates 33.

[0029] In actual operation, the rotating part 21 drives the grinding cylinder 22 to rotate on the frame body 1. Through this rotational movement, the graphite raw materials inside the grinding cylinder 22 are fully turned and mixed, avoiding the accumulation and dead corners of the raw materials during the grinding process, ensuring the uniformity of grinding. The driving part 32 drives the grinding roller 31 to rotate relatively. When the graphite raw materials are turned inside the grinding cylinder 22 along with the rotation of the cylinder body, they will be continuously ground by the rotating grinding roller 31, thereby achieving the purpose of refining the particles.

[0030] The partition plates 33 inside the grinding cylinder 22 are located on both sides of the grinding roller 31, and they play a role in separating and guiding, enabling the graphite raw materials to pass orderly through the gaps between the grinding rollers 31 during the grinding process.

[0031] The filter sheet 34 is used to screen the ground graphite particles to ensure that the particle size meets the requirements.

[0032] In this way, through the rotation of the flipping mechanism 2 and the grinding of the grinding mechanism 3, the graphite raw materials can be ground in all directions, avoiding the dead corners and raw material accumulation problems in traditional rolling grinding, thereby improving the uniformity of grinding.

[0033] Through the combined action of the rotation of the grinding cylinder 22 and the rotation of the grinding roller 31, the graphite raw materials can reach the required particle size in a relatively short time, improving the grinding efficiency.

[0034] It should be noted that in this implementation scheme, the filter sheet 34 is formed by splicing two semi-circular filter meshes, and the semi-circular filter meshes are located at the bottom of the corresponding grinding roller 31.

[0035] The filter sheet 34 is formed by splicing two semi-circular filter meshes. This design enables the filter mesh to cover the bottom area of the grinding roller 31 more comprehensively, thereby improving the filtering effect and ensuring that the ground graphite particles can pass through the filter mesh more accurately to meet the expected particle size requirements.

[0036] In this implementation scheme, the inside of the grinding cylinder 22 has a chamber for graphite grinding. The grinding cylinder 22 is provided with a feeding port, and a discharge valve is arranged at the bottom of the grinding cylinder 22. A sealing cover is hinged on the feeding port.

[0037] The inside of the grinding cylinder 22 has a chamber for graphite grinding. Through the feeding port arranged on the grinding cylinder 22, graphite raw materials can be put into the grinding chamber. Along with the rotation of the grinding cylinder 22 and the rotation of the grinding roller 31, the graphite raw materials are continuously ground and refined in the grinding chamber. The ground graphite particles, under the action of gravity and rotational force, pass through the screening of the filter sheet 34 and finally are discharged from the discharge valve at the bottom of the grinding cylinder 22.

[0038] Specifically, in this implementation, the rotating member 21 includes support seats 211 oppositely arranged on the frame body 1. A rotating shaft 212 is rotatably arranged on the support seats 211. The grinding cylinder 22 is rotatably arranged between the two rotating shafts 212. A first driving motor 213 is arranged on one side of the support seat 211. The output shaft of the first driving motor 213 is connected to one end of any rotating shaft 212.

[0039] Rotating shafts 212 are rotatably arranged on both support seats 211, and the grinding cylinder 22 is rotatably arranged between the two rotating shafts 212. The rotation of the grinding cylinder 22 is realized by the rotation of the rotating shafts 212. When the first driving motor 213 is started, it will drive the connected rotating shaft 212 to rotate, and then through the linkage of the rotating shafts 212, the whole grinding cylinder 22 rotates on the frame body 1.

[0040] Specifically, in this implementation, the driving member 32 includes a housing 321 arranged at one end of the grinding cylinder 22. A second driving motor 322 is arranged inside the housing 321. One end of the grinding roller 31 extends into the housing 321. The output shaft of the second driving motor 322 is connected to one end of any grinding roller 31. A gear 323 located inside the housing 321 is arranged on the grinding roller 31. The two gears 323 mesh with each other.

[0041] One end of the grinding roller 31 extends into the housing 321 and is directly connected to the output shaft of the second driving motor 322. When the second driving motor 322 is started, it will drive the connected grinding roller 31 to rotate. Gears 323 are arranged on both grinding rollers 31, and the two gears 323 mesh with each other. When one grinding roller 31 is driven to rotate by the second driving motor 322, through the meshing of the gears 323, the other grinding roller 31 will rotate in the opposite direction, so that a relative rotational movement can be formed between the two grinding rollers 31, thereby more effectively grinding the graphite raw material.

[0042] Preferably, a stabilizing mechanism 4 is further included in this implementation. The stabilizing mechanism 4 includes two inner sliding sleeves 41 oppositely arranged on the grinding cylinder 22. An outer sleeve 42 is slidably arranged on the outer side of the inner sliding sleeve 41. The bottom of the outer sleeve 42 is fixedly connected to the frame body 1. A number of steel balls adapted to the inner sliding sleeve 41 are embedded inside the outer sleeve 42.

[0043] When the grinding cylinder 22 rotates driven by the rotating member 21, the inner sliding sleeve 41 will slide along the inner wall of the outer sleeve 42. Since steel balls are embedded inside the outer sleeve 42, these steel balls will roll on the outer surface of the inner sliding sleeve 41, thereby reducing the frictional resistance between the inner sliding sleeve 41 and the outer sleeve 42 and making the rotation of the grinding cylinder 22 smoother.

[0044] Meanwhile, the rolling of the steel balls also plays a role in supporting and guiding, helping the inner sliding sleeve 41 maintain a stable sliding trajectory inside the outer sleeve 42, thereby ensuring the stability of the grinding cylinder 22 during rotation.

[0045] In this embodiment, the partition plate 33 is arranged on the inner wall of the grinding cylinder 22. One end of the partition plate 33 is close to the grinding teeth on the corresponding grinding roller 31, and a cavity 6 is formed inside the partition plate 33.

[0046] The partition plate 33 is located on the inner wall of the grinding cylinder 22, and one end is close to the grinding teeth on the corresponding grinding roller 31, so that during the grinding process of the graphite raw material, under the guiding action of the partition plate 33, it can be more effectively ground by the grinding teeth of the grinding roller 31.

[0047] It should be noted that a cavity 6 is formed inside the partition plate 33. The design of this cavity 6 has multiple functions. First of all, the cavity 6 can reduce the weight of the partition plate 33, making the grinding cylinder 22 more flexible and lighter when rotating. Secondly, the cavity 6 can also serve as a buffer area. When vibrations or impacts occur during the rotation of the grinding cylinder 22, the cavity 6 can absorb part of the energy, thereby reducing damage to the equipment.

[0048] As a preferred embodiment, the flushing mechanism 5 in this embodiment further includes a water injection joint 51 oppositely arranged on the grinding cylinder 22. One end of the water injection joint 51 is communicated with the cavity 6, and a plurality of spray heads 52 are embedded at one end of the partition plate 33 close to the grinding roller 31, and the other ends of the spray heads 52 are communicated with the cavity 6.

[0049] The grinding device in this embodiment adds a flushing mechanism 5 on the original basis, which can clean the inside of the grinding cylinder 22 and remove impurities and grinding residues attached to the inside of the grinding cylinder 22.

[0050] The water injection joint 51 is arranged on the grinding cylinder 22. When cleaning is required, one end is connected to an external water source, and the other end is communicated with the cavity 6 inside the partition plate 33. When flushing is required, clean water is injected into the cavity 6 through the water injection joint 51.

[0051] A plurality of spray heads 52 are embedded at one end of the partition plate 33 close to the grinding roller 31, and the other ends of these spray heads 52 are also communicated with the cavity 6. When the clean water enters the cavity 6, it will be sprayed out in the form of fine water mist or water flow through the spray heads 52, directly acting on the grinding roller 31, washing the impurities and grinding residues on its surface, and through the flipping mechanism 2, flushing the inner wall of the grinding cylinder 22, the filter plate 34 and the partition plate 33 to remove the impurities and grinding residues attached thereto.
