▎ 摘　　要

NOVELTY - The device has a barrel, a fixed graphite rod (3), a movable graphite rod (6), a driving mechanism, a support mechanism, an adjusting mechanism and a circulation mechanism. The barrel and the driving mechanism are fixed by the support mechanism. The fixed graphite rod and the movable graphite rod are arranged coaxially and spaced apart by a preset distance. The moving graphite rod rotates in a circle under the drive of the driving mechanism. The fixed graphite rod and the movable graphite rod are arranged coaxially. A top of the barrel is provided with a feed port (1), and the movable graphite rod is provided with a feed port that is coaxially arranged with the feed port. An upper end of the movable graphite rod is provided with a blind hole (32) corresponding to the feed port. An upper end of the fixed graphite rod and a lower end of the movable graphite rod are respectively connected with a power cord (12), and the power cord is connected with an external power source. USE - Device for preparing graphene composite material (claimed). ADVANTAGE - The overall structure of the device is simple, no need to manufacture graphene first, no high temperature melting metal solution is needed, and high temperature melting non-metallic solution, graphene composite metal, non-metallic material is produced at normal temperature. The production process of the device is less, suitable for automatic operation, and the entire production process has no pollution, no waste gas, no waste water, no waste discharge, and the graphene is uniformly doped. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the internal structure of the device for preparing graphene composite material.
