▎ 摘　　要

NOVELTY - The device has a feeding pipe (2) and a discharging pipe (3) that are arranged in parallel to the kettle structure. The feeding tube is provided at the top of a kettle structure (1), and the discharge tube is provided at the bottom of kettle structure. An auxiliary mechanism and a stirring mechanism are arranged in the kettle structure. The agitation mechanism includes a drive assembly and at least two agitating assemblies, the drive assembly including a drive motor (4), an internal gear, and a drive shaft. The sealing rod passes through the moving ring and is sealingly connected with the moving ring. One end of sealing rod near the support plate is fixed to the bottom of floating box by a connecting rod. A reset unit is provided in the pontoon, and the sealing rod is located between the reset units. The reset unit drives the moving ring to move away from the support plate along the axis of sealing rod. USE - Sealed reaction device with limited function for graphene production. ADVANTAGE - The device realizes the function of stirring the raw material through stirring mechanism, and too many raw materials in the kettle which cause safety accidents can be avoided. The safety can be improved. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the sealed reaction device.
