[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 1-3 As shown, a graphene powder preparation device comprises a powder collecting cylinder 1, a grinding cylinder 2 and an outer cylinder 3 which are sequentially arranged from the axis to the outside;

[0032] The powder collecting cylinder 1 is provided with cleaning members 4 arranged in a circumferential array, and the cleaning members 4 are used to sweep the inner wall of the grinding cylinder 2;

[0033] The outer wall of the grinding cylinder 2 is provided with first grinding portions 21 arranged in a circumferential array;

[0034] The inner wall of the outer cylinder 3 is provided with second grinding parts 22 arranged in a circumferential array, and the second grinding parts 22 are slidably connected to the first grinding parts 21;

[0035] A scraping groove 100 is formed on the second grinding part 22 facing the first grinding part 21 , and a compensation block 5 is slidably arranged in the scraping groove 100 . The compensation block 5 keeps periodic sliding to shrink into the scraping groove 100 , or extend to the outside of the scraping groove 100 and switch between being flush with the second grinding part 22 and the first grinding part 21 .

[0036] Specifically, a third stainless steel filter is provided on the grinding cylinder 2 in the embodiment, and the third stainless steel filter is arranged symmetrically with respect to the center of the first grinding portion 21 .

[0037] Secondly, it also includes a base 6, and the grinding cylinder 2 is fixedly installed on the base 6; while the outer cylinder 3 and the powder collecting cylinder 1 are rotatably arranged on the base 6 and are driven to rotate by a driving motor fixedly installed on the base 6.

[0038] The driving motor in the embodiment can drive the outer cylinder 3 and the powder collecting cylinder 1 to rotate simultaneously, and can be driven by a gear set, a transmission belt, or any other transmission method known to those skilled in the art.

[0039] In the above technology, the outer cylinder 3 rotates to make the second grinding part 22 contact with the first grinding part 21. During the process, the scraping groove 100 scrapes the graphene particles that fall on the grinding cylinder 2 and then enters the scraping groove 100 as it is scanned. When the second grinding part 22 contacts the first grinding part 21, the compensation block 5 is driven to extend to the outside of the scraping groove 100 and switch between being flush with the second grinding part 22 and the first grinding part 21, thereby achieving grinding.

[0040] The ground powder will seep into the powder collecting cylinder 1 through the grinding cylinder 2 and be sucked out, thereby obtaining graphene powder.

[0041] As an embodiment further provided by the present invention, a first stainless steel filter screen 7 is provided on the powder collecting barrel 1, and the first stainless steel filter screen 7 is symmetrically arranged about the cleaning member 4. The driving motor in the embodiment is also used to drive the powder collecting barrel 1 to rotate, so that the cleaning member 4 cleans the third stainless steel filter screen to prevent the third stainless steel filter screen from being blocked.

[0042] As another embodiment further provided by the present invention, the powder collecting tube 1 and the base 6 are plug-in, and the mounting portion at one end of the powder collecting tube 1 is threadedly assembled with the base 6;

[0043] A second stainless steel filter screen 8 is provided at one end of the mounting portion facing the powder collecting tube 1;

[0044] Also included is an exhaust fan fixedly connected to the mounting portion.

[0045] Specifically, during the operation of the above embodiment, the exhaust fan operates to suck the graphene powder inside the powder collecting cylinder 1 and then discharges it into the storage container. During the suction process, the outside air enters from the sealing door hinged on the outer cylinder 3.

[0046] As another embodiment further provided by the present invention, the first grinding portion 21 and the second grinding portion 22 are both fin-shaped;

[0047] The fish-fin type includes an arc-shaped surface, and the arc-shaped surfaces of the first grinding portion 21 and the second grinding portion 22 are arranged facing each other.

[0050] Furthermore, a bent rod 9 movably connected to the compensation block 5 is rotatably provided on the mounting seat 31 .

[0051] Specifically, when the arc surface of the first grinding part 21 contacts the arc surface of the second grinding part 22, it is pushed by the second grinding part 22 so that the first grinding part 21 deflects with the waist groove 33 as the moving path. During the upward movement, the curved rod 9 pushes the compensation block 5, driving the compensation block 5 to extend to the outside of the scraping groove 100 and switch between being flush with the second grinding part 22 and the first grinding part 21, thereby achieving grinding.
