▎ 摘　　要

NOVELTY - A high safety coefficient sealed reactor comprises kettle body (1), feeding pipe (2), discharging pipe, sealing cover, transmission shaft (5), and stirrer (6). The transmission shaft and stirrer are arranged in the kettle body. The transmission shaft is coaxially arranged with the kettle body. The feeding pipe is arranged on the top of the kettle body. The sealing cover is installed at the bottom end of the discharging pipe. The reactor further comprises driving mechanism, protecting mechanism, driving component, rotating tube, connecting bearing, protective component, fixed ring, connecting plate, connecting unit, connecting plate, connecting hole, sliding rod, fixed block, first spring, locking ring, connecting rod (15), connecting pipe, moving rod, supporting block, second spring, push plate, and locking block. USE - The high safety coefficient sealed reactor is used for producing graphene. ADVANTAGE - The reactor avoids pressure leakage and has improved security. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the high safety coefficient sealed reactor. Kettle body (1) Feeding pipe (2) Transmission shaft (5) Stirrer (6) Connecting rod (15)
