▎ 摘　　要

NOVELTY - The graphene preparation device has a feeding hopper for containing graphene raw materials, and a crushing barrel communicated and arranged below the feeding hopper, where the crushing barrel is a cylindrical structure and is sealed at both ends. A grinding roller is coaxially rotated and arranged inside the crushing barrel, where the side wall of the grinding roller is provided with an embedded spiral groove. A second motor is fixedly installed on the crushing barrel, and is used to drive the grinding roller to rotate. A peeling barrel is arranged at the bottom of the crushing barrel, and a switch driver is installed on the peeling barrel and connected with the cover door. A water pump is connected to a stripping bucket through a pipeline, and is used to drive the stripping agent in a stripping agent tank into the inside of the stripping bucket. USE - Device for preparing graphene. ADVANTAGE - The device improves the dispersion degree of graphene by cracking, inflating and breaking the graphene, and crushing and grinding by extrusion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a process for preparing graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene preparation device.
