▎ 摘　　要

NOVELTY - The device has a horizontal plate (6) whose one end is extended to the inside of a box main portion (2) and is fixedly connected to an inner side wall of the box main portion. A cavity is defined in the horizontal plate. A threaded rod (4) is rotatably connected in the cavity. The threaded rod is screwed to a moving block. A lower end of a through pipe is extended below a cover (3) and is fixedly connected with a support plate. A lower end of the support plate is symmetrically fixedly connected with two springs. The lower ends of the two springs are fixedly connected with a fixing plate. A lower end of the fixing plate is provided with a hood which is set in communication with the through pipe through a first telescoping tube. USE - Device for preparing highly oriented pyrolytic graphite based on graphene oxide. ADVANTAGE - The device is stable in structure, simple to operate, scientific and reasonable in design. The production cycle is short. The graphene requiring pyrolysis can be stably moved to the inside of the box for processing. The graphene can be better protected during pyrolysis, so that graphene is not be damaged and can be more accurately positioned and pyrolyzed according to people's needs. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the device for preparing highly oriented pyrolytic graphite based on graphene oxide.
