Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically to a grinding disc for the production and processing of carbon nanotubes. Background Technology

[0002] Carbon nanotubes, also known as buckytubes, are coaxial cylindrical tubes composed of several to dozens of layers of carbon atoms arranged in a hexagonal pattern. The layers maintain a fixed distance from each other, and they can be classified into three types based on the different orientations of the carbon hexagons along the axial direction: zigzag, armchair, and helical. Helical carbon nanotubes are chiral, while zigzag and armchair carbon nanotubes are not.

[0003] An existing patent, application number CN202120910699.0, discloses a grinding disc for carbon nanotube production and processing, comprising a grinding chamber, a feed pipe, a movable shaft, and a small shaft. An upper grinding disc is rotatably mounted on the upper inner wall of the grinding chamber, and a main shaft block is welded to the top of the upper grinding disc. The small shaft is rotatably mounted inside the upper grinding disc, with an eccentric disk welded to one end and a small shaft block welded to the other end. The movable shaft is slidably mounted on the bottom inner wall of the grinding chamber, and a lower grinding disc is welded to one end of the movable shaft. The lower grinding disc is located at the lower inner end of the grinding chamber. A connecting rod is bolted to the other end of the movable shaft, and a pneumatic rod is mounted at the bottom of the connecting rod. The feed pipe is embedded in the grinding chamber, and one end of the feed pipe is movably inserted into the lower grinding disc.

[0004] Existing patent, application number CN202123400075.3, discloses a graphene carbon nanotube slurry grinding device, comprising: a material placement assembly, which includes a grinding box, a partition shell, a shell cover, and slurry inlet pipes; the grinding box is annular with an internal grinding annular groove having a semi-circular cross-section and a large number of filter holes evenly distributed at the bottom; the partition shell is annular and vertically fixedly connected to the inner ring of the grinding box; the shell cover is fitted onto the outside of the grinding box; and multiple slurry inlet pipes are fixedly installed inside the grinding box; and a grinding assembly, which includes a rotating machine, a mounting frame, drive columns, and grinding balls; the rotating machine is fixedly installed at the center of the top wall of the shell cover; the mounting frame is connected to the rotating end below the rotating machine; and multiple drive columns are fixedly connected to the lower end of the mounting frame. This invention can simultaneously grind large quantities of slurry, improving the efficiency of raw material grinding while reducing manual labor.

[0005] However, although the aforementioned patent uses a power device to drive the main shaft block and the small shaft block to rotate via a chain, thereby causing the upper grinding disc and the eccentric disc to rotate, and thus creating a speed difference between the two grinding discs and the eccentric disc to achieve grinding, there is only one grinding method. When grinding materials, the grinding equipment requires a long time to grind larger materials, and the material is not processed evenly during grinding, resulting in poor grinding effect.

[0028] Combined with appendix Figures 1-4 A grinding disc for carbon nanotube production and processing includes, from top to bottom, a first fixed grinding disc 1, a first movable grinding disc 2, a second fixed grinding disc 3, and a second movable grinding disc 4. The upper and lower ends of the first movable grinding disc 2 are embedded in the first fixed grinding disc 1 and the second fixed grinding disc 3 and can rotate for grinding. The upper end of the second movable grinding disc 4 is embedded in the second fixed grinding disc 3 and can rotate for grinding. A protective shell 5 is installed on the outside of the second movable grinding disc 4. A drive motor 6 is fixedly installed inside the protective shell 5. A rotating block 601 is installed at the output end of the drive motor 6. The rotating block 601 is fixedly connected to the second movable grinding disc 4 and passes through the second fixed grinding disc 3 and is inserted into the first movable grinding disc 2. A rod is installed on the protective shell 5 to limit the first fixed grinding disc 1 and the second fixed grinding disc 3. The first movable grinding disc 2 and the second movable grinding disc 4 rotate between the first fixed grinding disc 1 and the second fixed grinding disc 3 to grind carbon nanotubes. There are three grinding areas and three different grinding methods.

[0029] In specific implementation of this utility model, such as Figure 3 and Figure 4 As shown, a grinding ball 101 is installed at the lower end of the first fixed grinding disc 1, and a first grinding groove 201 is opened on the upper end surface of the first movable grinding disc 2 to cooperate with the grinding ball 101. When the first movable grinding disc 2 rotates, the first grinding groove 201 rotates outside the grinding ball 101 to achieve grinding of carbon nanotubes.

[0030] In a specific implementation of this utility model, a material passage groove 11 is opened on the outer side of the grinding ball 101, and the lower end of the material passage groove 11 can be connected to the discharge hole 9 of the first movable grinding disc 2. Furthermore, the opposing surfaces of the grinding ball 101, the first grinding groove 201, the first grinding block 202, and the second grinding groove 301 are all roughly arranged, which facilitates the introduction and grinding of materials.

[0031] A first grinding block 202 is installed at the lower end of the first movable grinding disc 2, and a second grinding groove 301 is formed on the upper surface of the second fixed grinding disc 3 to cooperate with the first grinding block 202. The first movable grinding disc 2 rotates, causing the first grinding block 202 to rotate and grind carbon nanotubes in the second grinding groove 301.

[0032] In specific implementation of this utility model, such as Figure 4 As shown, the lower end of the first grinding block 202 is provided with a limiting groove 203 for use with the rotating block 601. The rotating block 601 can be a cuboid structure. The drive motor 6 works to drive the second fixed grinding disk 3 to rotate first. By inserting the rotating block 601 into the limiting groove 203, the first movable grinding disk 2 is driven to rotate.

[0033] A through hole 302 is provided on the second fixed grinding disc 3 to cooperate with the rotating block 601.

[0034] In specific implementation of this utility model, such as Figure 3 and Figure 4 As shown, multiple sets of staggered second grinding blocks 8 are installed on the opposite surfaces of the second fixed grinding disk 3 and the second movable grinding disk 4. When the second movable grinding disk 4 rotates, the staggered second grinding blocks 8 can drive the second grinding blocks 8 on the second movable grinding disk 4 to rotate, and the second grinding blocks 8 of the second fixed grinding disk 3 can grind carbon nanotubes.

[0035] The first movable grinding disc 2 and the second fixed grinding disc 3 have discharge holes 9 for discharging material, and the first fixed grinding disc 1 has a feed inlet 10 for feeding material. Specifically, carbon nanotubes can be fed into the feed inlet 10, ground by the grinding balls 101 in the first grinding tank 201, and then enter the second grinding tank 301 through the discharge holes 9. After being ground by the first grinding blocks 202, they enter the space between the second fixed grinding disc 3 and the second movable grinding disc 4 for further grinding.

[0036] In specific implementation of this utility model, such as Figure 1 and Figure 4As shown, the limiting device 7 includes a mounting block 701 disposed opposite to the outside of the first fixed grinding disc 1 and the second fixed grinding disc 3. A limiting post 702 is mounted opposite to the protective shell 5 and passes through the mounting block 701. A fixing block 703 supporting the mounting block 701 is mounted on the outside of the limiting post 702. The fixing block 703 has a mounting hole 704. Specifically, the diameter of the mounting hole 704 of the mounting block 701 that is matched with the second fixed grinding disc 3 is larger than the diameter of the fixing block 703 that is matched with the mounting block 701 of the first fixed grinding disc 1. This allows the second fixed grinding disc 3 to pass through the fixing block 703 that is matched with the first fixed grinding disc 1 and be installed above the second movable grinding disc 4. At the same time, it makes it easy to disassemble the second fixed grinding disc 3.

[0037] Two limiting posts 702 can restrict the position of the first fixed grinding disc 1 and the second fixed grinding disc 3, preventing the first fixed grinding disc 1 and the second fixed grinding disc 3 from rotating. At the same time, the fixing block 703 supports the first fixed grinding disc 1 and the second fixed grinding disc 3, so that the first movable grinding disc 2 and the second movable grinding disc 4 can rotate between the first fixed grinding disc 1 and the second fixed grinding disc 3.

[0038] In specific implementation of this invention, the feed particle size is 50-100μm carbon nanotube aggregates; the discharge particle size is D50≤200nm after 15 minutes of grinding, and the distribution index PDI<0.3.

[0039] The working principle of this utility model:

[0040] The second fixed grinding disc 3, the first movable grinding disc 2, and the first fixed grinding disc 1 are installed sequentially using the limiting device 7. The rotating block 601 is inserted into the limiting groove 203, and the drive motor works to rotate the first movable grinding disc 2 and the second movable grinding disc 4. Carbon nanotubes are fed into the feed port 10, ground by the grinding balls 101 in the first grinding groove 201, and enter the second grinding groove 301 through the discharge hole 9. After being ground by the first grinding block 202, they enter the space between the second fixed grinding disc 3 and the second movable grinding disc 4 for further grinding.

[0041] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
