▎ 摘　　要

NOVELTY - The device has a fixing frame (1) whose the top surface of the fixing frame is provided with holes on the left and right sides. The metal rubber tube (8) penetrates the connecting shaft B (7) and is connected with the heater (9). The top surface of the connecting shaft B is provided with a hole and a heat insulation cylinder is fixedly connected in the hole. The spray pipe is provided with a hole in the center and is fixedly connected with the spray pipe. The bottom end of the spray pipe is located in the spherical preparation container (2) between the metal rubber pipes. The outer wall of the connecting shaft B is fixedly connected with a fixing ring (12) on the outer wall. A connecting rod (13) is sleeved on the inner wall of the fixing ring. The end of the connecting rod far away from the fixed ring is fixedly connected with a telescopic mechanism (14). USE - Device for preparing graphene aluminum alloy powder. Uses include but are not limited to optical, electrical, mechanical property, material learning, micro-nano processing, energy, biological medicine and medicine transmission. ADVANTAGE - The metal rubber pipe is used for scraping the inner wall of the spherical preparation container, so as to reach better cleaning effect and higher cleaning efficiency. The stop block automatically seals the air cylinder after finishing cleaning, which avoids the problem that the powder in the container is dispersed to pollute the environment. The portion of the powder is not filtered and tightly adhered to the powder for the second time drying. DESCRIPTION OF DRAWING(S) - The drawing shows a front sectional view of the device for preparing graphene aluminum alloy powder.
