▎ 摘  要

NOVELTY - The device has a separating cylinder (1) formed with a separating cavity. The separating cavity is divided into a discharging cavity and a filtering cavity along axial direction of the separating cylinder. A material pressing piston (2) is limited in the filtering cavity. A limiting piston (3) is limited in the discharging cavity. The pressing piston moves independently in the filtering cavity when axial distance between the pressing piston and the limiting piston is greater than a set threshold value. An end of a feeding pipe (4) is limited between the pressing piston and the limiting piston. USE - Device for separating and oxidizing graphene by a ceramic composite film. ADVANTAGE - The device can effectively avoid the limiting piston from the discharging cavity to conveniently and accurately switch to a state of the pressing piston independently moving. A telescopic piece is rotatably connected with the piston through a mounting plate to realize material stirring based on rotation of the telescopic piece in a process of moving the piston to conveniently realize fully separation of the material. A filtering and separating effect is good and efficiency is high.
