▎ 摘　　要

NOVELTY - The preparation device has a barrel, a fixed graphite rod (3), a moving graphite rod (6), a driving mechanism, a supporting mechanism, an adjusting mechanism and a circulation mechanism. The adjustment mechanism is provided between the barrel and the support mechanism. The upper end of the fixed graphite rod is fixed on the top end of the barrel. The upper end of the movable graphite rod is fixed on the driving mechanism. The movable graphite rod rotates in a circle under the drive of the driving mechanism. The top end of the barrel portion is provided with a feed port (1). The movable graphite rod is provided with the feed port. The upper end of the movable graphite rod is provided with a blind hole (32) corresponding to the feed port. The upper end of the fixed graphite rod and the lower end of the movable graphite rod are respectively connected with a power cord (12). The power cord is connected with an external power source. USE - Graphene mixed solution (claimed) preparation device. ADVANTAGE - The overall structure of the graphene mixed solution preparation device is simple. The production process of the graphene mixed solution is less, which is suitable for automatic operation. The entire production process has no pollution, no waste gas, no waste water, no waste discharge, and the graphene is uniformly doped. The need to manufacture graphene first is eliminated, thus high temperature melting metal solution does not needed. The high temperature melting non-metallic solution, graphene composite metal, non-metallic material are produced at normal temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene mixed solution preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of graphene mixed solution preparation device.
