▎ 摘　　要

NOVELTY - The preparation and cleaning device comprises cleaning tank (1). The four corners of the inner wall of the cleaning tank are fixedly installed with a cylinder (3), and the top of the cylinder is fixedly connected with a top cover (2). A drawer (9) is slidingly connected to a side wall of the top cover, and a lower pressure plate (7) is placed in an inner cavity of the drawer. The two sets of clamping slots (8) are opened on the top side of the lower pressing plate, and six groups of connecting rods (10) are fixedly connected to the bottom side of the lower pressing plate. The bottom of the six groups of the connecting rods are fixedly connected to the clamps (11) through the bottom of the drawer, and the top of the inner cavity of the top cover is fixedly installed with two sets of motors (4) and brackets (5). An eccentric rotating roller (6) is rotatably connected between the two groups of the motor and the bracket. USE - Preparation and cleaning device used for modified graphene block. ADVANTAGE - The preparation and cleaning device has simple structure, convenient and practical, and vibrating screen can turn the graphene block in the screen to an angle, which is convenient for washing in various directions and enhances the cleaning effect.
