▎ 摘　　要

NOVELTY - The device has telescopic frame whose top ends are hinged with a sliding ring and a cover plate (7), and the shape of the sliding rail is U-shaped. Both ends of the slide rail are fixed below the cover plate, and the slide ring is sleeved on a horizontal portion of the slide rail. The stirring mechanism is comprised with a telescopic component, a flat plate, a rotating component, a vertical pipe (17), a supporting component and two stirring plates (18). The telescopic component is drivingly connected with flat plate. The flat plate is sleeved on a discharge pipe, and the top of vertical pipe is sleeved on discharge pipe. The vertical pipe is arranged below flat plate through a supporting component. The rotating component located under flat plate is drivingly connected to vertical pipe. The bottom end of vertical pipe is comprised in beaker (6) through a cover plate, and two stirring plates are located on both sides of bottom end of vertical pipe, respectively. USE - Energy-saving reaction device for producing graphene. ADVANTAGE - The production quality of the graphene is ensured, and improved practicability is achieved. Enhanced energy-saving effect is achieved. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the energy-saving reaction device.
