Description

Technical Field

[0001] The present invention relates to the field of crushing and grinding, and more specifically, to an efficient crushing and grinding process and device for ultrafine graphite powder. Background Art

[0002] Graphite is an allotrope of carbon, a grayish-black, opaque solid with stable chemical properties, corrosion resistance and is not easily reactive with chemicals such as acids and alkalis. It can be used in the production of refractory materials, conductive materials, wear-resistant materials, lubricants and high-temperature resistant sealing materials, etc. These materials are widely used in fields such as metallurgy, petrochemical industry, machinery industry, electronic industry, nuclear industry and national defense. When processing graphite, it is necessary to first perform crushing and grinding on the raw materials.

[0003] For example, the utility model patent CN214515071U discloses an environment-friendly crushing and grinding device for graphite processing. By setting a grinding chamber, there are two meshing gears, a first gear and a second gear, inside the grinding chamber. Driven by a first rotating shaft, the first gear can drive the second gear to rotate. The grinding rollers and grinding knives at one end of the two gears will rotate meshingly under the drive of the gears, and can perform strong and relatively complete crushing and rolling on the graphite raw materials, greatly improving the working quality of the crushing and grinding process for graphite raw materials; However, the above patent document only has the function of single-time grinding and processing together. In actual use, there is no structure that can separate the ground and incompletely ground graphite powder raw materials, resulting in the mixing of the ground and incompletely ground graphite powder raw materials, and secondary grinding is required. At the same time, there is also a lack of large-piece crushing treatment for the graphite powder raw materials before grinding, resulting in the graphite powder raw materials remaining in a large-piece state before grinding, which affects the grinding effect.

The partition plate is arranged in a horizontal state. The top of the partition plate is in mutual fit with the bottom of the filter plate. The area of the partition plate is the same as the area of the bottom of the filter plate.

[0008] In a preferred embodiment, a plurality of clamping blocks are fixedly installed on the top of the partition plate. The plurality of clamping blocks are arranged in a vertical state. The plurality of clamping blocks are arranged corresponding to the filter plate. The heights of the plurality of clamping blocks are the same as the height of the filter plate.

[0009] In a preferred embodiment, the impact mechanism includes a magnet ring fixedly installed on the outer wall of the belt roller frame. The cross-sectional area of the magnet ring is smaller than the cross-sectional area of the rolling roller. A notch is formed at the bottom of the magnet ring. The notch is arranged vertically downward.

[0010] In a preferred embodiment, a plurality of iron plates are slidably installed on the inner wall of the rolling roller. The outer walls of the plurality of iron plates are arranged corresponding to the outer wall of the magnet ring. The plurality of iron plates are arranged in a circumferentially equidistant manner. A heavy impact block is fixedly installed on one side of the plurality of iron plates. The heavy impact block is arranged corresponding to the inner wall of the rolling roller.

[0011] In a preferred embodiment, a top supporting and impact mechanism is arranged on both sides of the belt roller frame. The top supporting and impact mechanism includes telescopic rods fixedly installed on the tops of both sides of the belt roller frame. The two telescopic rods are arranged vertically downward. A pressing plate is fixedly installed at the bottom of the two telescopic rods. The bottom of the pressing plate is in mutual fit with the top of the filter plate.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1: In view of the fact that there is no structure in the prior art that can separate the ground and incompletely ground graphite powder raw materials, resulting in the mixing of the ground and incompletely ground graphite powder raw materials and the need for secondary grinding treatment, the following technical solutions are proposed to solve this problem: Referring to the attached drawings of the specification Figures 1-7 , a high-efficiency ultra-fine graphite powder crushing and grinding device, as Figure 1 and Figure 5 shown, includes a workbench frame 1, a filter plate 2 is fixedly installed on the top of the workbench frame 1, and a pressing and pushing separation mechanism 3 and an impact mechanism 4 are arranged on the top of the filter plate 2; As Figure 3 and Figure 4As shown in the figure, the pressing and separating mechanism 3 includes a motor 31 fixedly installed on the top of the workbench frame 1. There is a reciprocating threaded rod 32 on one side of the motor 31. The reciprocating threaded rod 32 is horizontally arranged. A belt roller frame 33 is threadedly connected to the outer wall of the reciprocating threaded rod 32. The belt roller frame 33 is horizontally arranged. A rolling roller 34 is rotatably installed on the outer wall of the belt roller frame 33. The rolling roller 34 is located on the top of the filter plate 2. The motor 31 drives the reciprocating threaded rod 32 so that the belt roller frame 33 can reciprocate, that is, the belt roller frame 33 drives the rolling roller 34 to grind the graphite powder raw material on the top of the filter plate 2.

[0026] As Figure 3 and Figure 4 shown in the figure, a pushing plate 35 is fixedly installed on one side of the belt roller frame 33. There is a cross plate 36 on one side of the pushing plate 35. Tooth plates 37 are fixedly installed on both sides of the cross plate 36. The two tooth plates 37 are slidably installed on the top of the workbench frame 1. The two tooth plates 37 are symmetrically arranged. Limiting springs 38 are fixedly installed on the outer walls of the two tooth plates 37. The limiting springs 38 are fixedly installed on the top of the workbench frame 1. When the belt roller frame 33 reciprocates and moves back, the belt roller frame 33 drives the pushing plate 35 to push the cross plate 36. At this time, the cross plate 36 drives the two tooth plates 37 to move backward synchronously and compress the limiting springs 38 under force.

[0027] As Figure 3 and Figure 4 shown in the figure, first gears 39 are respectively meshed with the bottoms of the two tooth plates 37. The first gears 39 are rotatably installed on the outer wall of the workbench frame 1. Second gears 310 are respectively meshed with the bottoms of the two first gears 39. A rotating rod 311 is fixedly installed on one side of the two second gears 310 together. The rotating rod 311 is rotatably installed on the outer wall of the workbench frame 1. A partition plate 312 is fixedly installed on one side of the rotating rod 311. The partition plate 312 is horizontally arranged. The top of the partition plate 312 is in mutual contact with the bottom of the filter plate 2. The area of the partition plate 312 is the same as the area of the bottom of the filter plate 2. The two tooth plates 37 drive the first gears 39 on both sides to rotate and make the second gears 310 synchronous. The two second gears 310 drive the rotating rod 311 to deflect downward. Furthermore, the rotating rod 311 drives the partition plate 312 to deflect downward from the bottom of the filter plate 2.

[0028] As Figure 3 and Figure 4As shown in the figure, a plurality of clamping blocks 313 are fixedly installed at the top of the partition plate 312. The plurality of clamping blocks 313 are arranged vertically and correspond to the filter plate 2. When the clamping blocks 313 are located in the holes of the filter plate 2, they are filled, which is convenient for the graphite powder on the filter plate 2 to be ground with a supporting effect. The heights of the plurality of clamping blocks 313 are the same as the height of the filter plate 2. Then, the partition plate 312 drives the plurality of clamping blocks 313 to deflect downward synchronously. At this time, the plurality of clamping blocks 313 are separated from the positions of the holes in the filter plate 2, that is, the leakage holes of the filter plate 2 are opened to discharge the ground graphite powder.

[0029] As Figure 5 shown, the impact mechanism 4 includes a magnet ring 41 fixedly installed on the outer wall of the belt roller frame 33. The cross-sectional area of the magnet ring 41 is smaller than the cross-sectional area of the rolling roller 34. A notch 42 is opened at the bottom of the magnet ring 41. The notch 42 is arranged vertically downward. Then, the magnet ring 41 and the notch 42 make the inner wall of the rolling roller 34 have a magnetic adsorption effect.

[0030] As Figure 5 shown, a plurality of iron plates 43 are slidably installed on the inner wall of the rolling roller 34. The outer walls of the plurality of iron plates 43 correspond to the outer wall of the magnet ring 41. The plurality of iron plates 43 are arranged at equal circumferential intervals. A heavy impact block 44 is fixedly installed on one side of the plurality of iron plates 43. The heavy impact block 44 corresponds to the inner wall of the rolling roller 34. Then, when the rolling roller 34 rotates, it drives the plurality of iron plates 43 and the heavy impact blocks 44 to rotate synchronously. And the magnet ring 41 makes the plurality of iron plates 43 be magnetically adsorbed. When one of the iron plates 43 rotates to the position of the notch 42, at this time, the iron plate 43 loses the magnetic adsorption effect and drives the heavy impact block 44 to impact the bottom of the rolling roller 34 under the action of gravity, which is convenient for improving the grinding strength of the rolling roller 34.

[0031] In specific implementation, the motor 31 drives the reciprocating threaded rod 32 so that the belt roller frame 33 can reciprocate, that is, the belt roller frame 33 drives the rolling roller 34 to grind the graphite powder raw material on the top of the filter plate 2. When the rolling roller 34 rotates, it drives the plurality of iron plates 43 and the heavy impact blocks 44 to rotate synchronously. And the magnet ring 41 makes the plurality of iron plates 43 be magnetically adsorbed. When one of the iron plates 43 rotates to the position of the notch 42, at this time, the iron plate 43 loses the magnetic adsorption effect and drives the heavy impact block 44 to impact the bottom of the rolling roller 34 under the action of gravity, which is convenient for improving the grinding strength of the rolling roller 34; When the roller frame 33 reciprocates and moves back once, the roller frame 33 drives the pushing plate 35 to push the cross plate 36. At this time, the cross plate 36 is stressed and drives the two toothed plates 37 to move backward synchronously and compress the limit spring 38. The two toothed plates 37 drive the first gears 39 on both sides to rotate and synchronize the second gears 310. Furthermore, the two second gears 310 drive the rotating rod 311 to deflect downward. Then, the rotating rod 311 drives the partition plate 312 to deflect downward from the bottom of the filter plate 2. Then, the partition plate 312 drives the multiple clamping blocks 313 to deflect downward synchronously. At this time, the multiple clamping blocks 313 are disengaged from the positions of the holes in the filter plate 2, that is, the leakage holes of the filter plate 2 are opened to facilitate the discharge of the ground graphite powder.

[0032] Embodiment 2: Aiming at the lack of large-piece crushing treatment for graphite powder raw materials before grinding in the prior art, which results in the large-piece state of the graphite powder raw materials before grinding and affects the grinding effect. To solve this problem, the following technical solutions are proposed: Such as Figure 1 、 Figure 6 and Figure 7 As shown, top support and crushing mechanisms 5 are arranged on both sides of the roller frame 33. The top support and crushing mechanism 5 includes telescopic rods 51 fixedly installed on the tops of both sides of the roller frame 33. The two telescopic rods 51 are arranged vertically downward. A crushing plate 52 is fixedly installed at the bottom of the two telescopic rods 51 together. The bottom of the crushing plate 52 is mutually attached to the top of the filter plate 2. Through the two telescopic rods 51, the crushing plate 52 can move up and down on one side of the roller frame 33 to crush the large-piece graphite powder raw materials on the filter plate 2.

[0033] Such as Figure 5 and Figure 7 As shown, cross bars 53 are fixedly installed on both sides of the crushing plate 52. The two cross bars 53 are arranged symmetrically with each other. A plurality of top support plates 54 are respectively arranged on both sides of the two cross bars 53. The plurality of top support plates 54 are rotatably installed on the top of the workbench frame 1. The plurality of top support plates 54 are arranged in a triangular shape. The outer wall of the top support plate 54 is mutually attached to the outer wall of the cross bar 53. Cushion blocks 55 are respectively arranged on both sides of the plurality of top support plates 54. The cushion blocks 55 are fixedly installed on the top of the workbench frame 1; During the movement of the roller frame 33, the roller frame 33 drives the crushing plate 52 and the cross bars 53 on both sides to move synchronously. Then, the cross bars 53 on both sides approach and push the top support plates 54 on both sides. Then, the top support plates 54 deflect to one side. And with the support of the cushion blocks 55, the pushed top support plates 54 are in an inclined state in the corresponding direction. Then, the top support plates 54 can lift the cross bars 53 to move upward. And after the cross bars 53 cross over the top support plates 54, the cross bars 53 quickly disengage from the tops of the top support plates 54 and fall, that is, the crushing plate 52 quickly falls and hits the large-piece graphite powder raw materials on the filter plate 2.

[0034] In specific implementation, during the movement of the belt roller frame 33, the belt roller frame 33 drives the pressing plate 52 and the cross bars 53 on both sides to move synchronously. Then, the cross bars 53 on both sides approach and push the supporting plates 54 on both sides. As a result, the supporting plates 54 deflect to one side. And with the support of the cushion blocks 55, the pushed supporting plates 54 are in an inclined state in the corresponding direction. Thus, the supporting plates 54 can lift the cross bars 53 upward. And after the cross bars 53 cross over the supporting plates 54, the cross bars 53 quickly separate from the top of the supporting plates 54 and fall downward, that is, the pressing plate 52 quickly falls and smashes the large graphite powder raw materials on the filter plate 2 for crushing treatment.

[0035] Embodiment 3: As Figures 1-7 shown, the present invention also proposes a high-efficiency crushing and grinding process for ultrafine graphite powder, which specifically includes separating graphite powder raw materials of different sizes and hammering and crushing large graphite powder raw materials. The relevant steps are as follows: Step 1: The motor 31 drives the reciprocating threaded rod 32 so that the belt roller frame 33 can reciprocate. That is, the belt roller frame 33 drives the rolling roller 34 to grind the graphite powder raw materials on the top of the filter plate 2. When the rolling roller 34 rotates, multiple iron plates 43 and heavy impact blocks 44 inside it impact the bottom of the rolling roller 34, which is convenient for improving the grinding strength of the rolling roller 34. Step 2: The belt roller frame 33 drives the pushing plate 35 to push the cross plate 36. The cross plate 36 is stressed to drive two toothed plates 37, causing the first gear 39 to rotate and the second gear 310 to synchronize. Then, the two second gears 310 drive the rotating rod 311 to deflect downward. Step 3: The rotating rod 311 drives the partition plate 312 to deflect downward from the bottom of the filter plate 2. The partition plate 312 drives multiple clamping blocks 313 to separate from the holes of the filter plate 2 and open, and discharge the already ground graphite powder. Step 4: The belt roller frame 33 drives the pressing plate 52 and the cross bars 53 on both sides to move synchronously. The cross bars 53 on both sides approach and push the supporting plates 54 on both sides to deflect to one side. Step 5: The supporting plates 54 lift the cross bars 53 upward. After the cross bars 53 cross over the supporting plates 54, they quickly separate from the top of the supporting plates 54 and fall downward, that is, the pressing plate 52 quickly falls and smashes the large graphite powder raw materials on the filter plate 2 for crushing treatment.
