▎ 摘　　要

NOVELTY - The device has a box body (1), a feed inlet (2) provided on the top plate of the box body, a feed funnel (3) fixedly connected to the side wall of the feed inlet and a material control mechanism provided at the feed inlet. The upper surface of the bottom plate of the box body is fixedly connected with a heater (4) and a motor (5), and a horizontal plate (6) is fixedly connected to the inner side wall of the box body. The output shaft of the motor passes through the through-hole on the side wall of the horizontal plate, and is fixedly connected with stirring rods (7). A charging barrel (8) is provided on the outside of the stirring rod, and the lower surface of the bottom plate of the barrel is fixedly connected to the upper surface of the horizontal plate. The bottom of the barrel is provided with a first discharge hole. The side wall of the horizontal plate is provided with a second discharge hole with a filter plate corresponding to the position of the first discharge hole. USE - The device is used for graphene synthesis. ADVANTAGE - The device effectively controls the feed rate of materials, and simultaneously facilitates the synthesis of graphene.
