▎ 摘　　要

NOVELTY - The vacuum drying device has vacuum heating tank (1), semi-elliptical cover (3), filter carrier exchange assembly and shifting component. The loading elastic material component is set in the semi-elliptical cover. A semi-elliptical rubber elastic sleeve port (31) and an inner conical hopper port are respectively hermetically installed on the circular hole upper and lower hole opening. The semi-elliptical rubber elastic sleeve port and semi-elliptical cover (EC) inner top portion (TP) are connected with each other through the reset spring (41). The iron core black is installed at the middle position top portion of the semi-elliptical rubber elastic sleeve. USE - Vacuum drying device for graphene oxide powder. ADVANTAGE - Vacuum drying device greatly improves the efficiency of instant evaporation of water in the diffusion process of powder, realizes the function of dry powder shifting and separating and discharging, at the same time, is convenient for fast replacing the powder collection thin screen plate, and ensures the continuity of the powder drying process. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a vacuum drying device for graphene oxide powder. 1Vacuum heating tank 2Vacuum pump 3Semi-elliptical cover 4Cylinder 5Side flat box 6Connecting plate 7Oil cylinder 8Outer conical hopper 9Electric valve one 10Discharging pipe 11Electric valve 12Feeding pipe 13Feeding hopper 14Feeding pump 51Motor
