▎ 摘　　要

NOVELTY - Graphene preparing device comprises a discharge part, a lifting part, gas circuit part, shell part. The discharge part is made of insulating convex base tube (1), a discharge electrode (6), cathode plate (7). The insulating convex base tube is a hollow cylindrical insulating tube, where insulating convex base tube is provided with a discharge electrode. The discharge electrode and the high-voltage power supply are connected. The head is bent to be ' 6 'shape with negative charging plate kept at a certain distance. The lifting part is the spiral lifting main body (8).The air path part is composed of rubber sealing pad (2), a ball valve and a stabilizing filler. The rubber sealing pad is arranged on the upper cover. The ball valve is connected with the base through the threaded hole stabilizing the filler which is uniformly filled in the ball valve. The shell part is composed of an upper cover, a glass shade and a base and the upper cover is opened with snake hole groove. USE - Used as graphene preparing device. ADVANTAGE - The device has compact structure, simple operation, and can quickly prepare the graphene powder. DETAILED DESCRIPTION - Graphene preparing device comprises a discharge part, a lifting part, gas circuit part, shell part. The discharge part is made of insulating convex base tube (1), a discharge electrode (6), cathode plate (7). The insulating convex base tube is a hollow cylindrical insulating tube, where insulating convex base tube is provided with a discharge electrode. The discharge electrode and the high-voltage power supply are connected. The head is bent to be ' 6 'shape with negative charging plate kept at a certain distance. The lifting part is the spiral lifting main body (8), where a spiral lifting plate passes through the threaded hole matched with the base. The air path part is composed of rubber sealing pad (2), a ball valve and a stabilizing filler. The rubber sealing pad is arranged on the upper cover. The ball valve is connected with the base through the threaded hole stabilizing the filler which is uniformly filled in the ball valve. The shell part is composed of an upper cover, a glass shade and a base and the upper cover is opened with snake hole groove. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene preparing device.
