▎ 摘　　要

NOVELTY - The device has a vibrating ring (1). A ring cabin (2) is arranged on a top surface of the vibration ring, and an ultrasonic generator (6) is arranged on outer wall of the ring cabin. The ultrasonic generator whose ends are provided with connecting rods (5) extending along annular outer wall of the ring cabin. An end of the connecting rod is provided with a vibrating head (7) which is connected to the ultrasonic generator and is fixed on outer wall of the ring cabin and vibrates the ring cabin. A top cover (12) is connected to top of the ring cabin through a hinge seat (11), and a heating pipe (1201) corresponding to a top of the ring cabin is provided in the top cover. An electrostatic generator (1202) is connected to the heating pipe is fixed on top surface of the top cover. A top of a spring is connected to a top of a sliding rail, and a stirring plate (9) moves upwards along the sliding rail, when a pressing ring (13) moves upwards, under the influence of the spring. USE - Device for preparing graphene material. ADVANTAGE - Since the graphene is installed on the vibration mechanism, the access base takes the graphene and rotates back into the ring chamber again, vibrates again through the vibration effect, so that the graphene is turned over with the vibration action, and receives in the ring chamber drying process. The graphene material after drying treatment for three times can improve product quality, and the multiple processes for preparing graphene are integrated into the device, which improves the work efficiency during graphene preparation. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the device for preparing graphene material.
