▎ 摘　　要

NOVELTY - The device has a storage tank (1), multi-stage microwave reaction kettle (4), spray drying tower (9) and cyclone centrifugal separator (10) that are connected by pipeline. The liquid storage tank is connected with mix groove (6). A fast stir paddle inner portion is set with booster pump (8). The liquid storage tank with spray drying tower is placed between the liquid storage grooves. Each level microwave reaction kettle of pipeline port is set with ultrasonic processor (3) having microwave combination mode and screen (5) whose side is set with two transverse rapid stir blades. USE - Continuous graphene powder production device. ADVANTAGE - The graphene large-scale production is realized with low cost, by using continuous ultrasonic microwave combination mode. The environment pollution is reduced and graphene powder production device is transported and used conveniently. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a continuous graphene powder production method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene powder production device.
