▎ 摘  要

NOVELTY - The utility model claims a vacuum reactor for preparing graphene by electrifying carbon powder, the anode and cathode respectively the power supply are connected with two electrode rods with sealing ring of the reactor, the electrode respectively is inserted into the reaction tube from two ends to seal, the middle of the reaction tube is placed with carbon powder, the side of the reaction tube is connected with the vacuum pump to vacuumize, two ends of the reaction tube are respectively embedded with a section of metal tube lining, the electrode bar with sealing ring and the metal tube lining are tightly contact to reach the effect of sealing. The reactor effectively reduces the friction between the sealing ring and the reaction tube, protects the sealing ring, convenient for vacuum reactor to realize automation.
