▎ 摘　　要

NOVELTY - The barrel has a tank body (1) whose front end is provided with a control panel (2). A top cover (3) is embedded in a middle side of a top side of the tank body. The tank body is provided with a cavity, a hydraulic arm, a supporting panel, an iron sheet and a liquid outlet. The cavity is fixed with a middle side of the tank body. The hydraulic arm is located on a middle side of a bottom side of the cavity. The supporting panel is transversely installed on a top end of the hydraulic arm. The liquid outlet is fixed on a side end of the tank body and passed through the cavity. USE - Graphene powder storage barrel. ADVANTAGE - The barrel throws an impact block to impact the iron sheet by utilizing inertia and vibrates an end surface of the iron sheet and graphene powder on the end surface of the iron sheet to remove the graphene powder. DESCRIPTION OF DRAWING(S) - The drawing shows a front perspective view of a graphene powder storage barrel. Tank body (1) Control panel (2) Top cover (3)
