▎ 摘　　要

NOVELTY - The device has a reaction vessel (1) whose top is provided with a first driving device (5). A first stirring shaft (6) is rotatably arranged in the reaction vessel. The inner bottom of the reaction vessel is provided with a matrix of magnetic cylinders. The top of a reaction kettle (3) is provided with a second driving device (8). The reaction kettle is provided with a second stirring shaft (9). The top of the second stirring shaft is drivingly connected with the driving end of the second driving device. The bottom of the reaction kettle is provided with an ultrasonic spray device (10). A circulation pump is arranged between ultrasonic stripping device (2) and the reaction kettle. The inlet end of the circulating pump is provided in communication with the outlet end of ultrasonic peeling device. The outlet end of the circulating pump is communicated with the inlet end of reactor (21). The outer surface of magnetic main housing matrix is coated with polytetrafluoroethylene resin. USE - Industrialized graphene preparation device. ADVANTAGE - The raw materials are respectively subjected to cyclic mixed magnetization, ultrasonic stripping and mixed refining treatment, so that the input graphite powder is completely stripped into graphene with nano-level size. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation process of graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the industrialized graphene preparation device.
