▎ 摘　　要

NOVELTY - The device has a static tank (1), a centrifuge and a waste liquid tank (2). The centrifuge comprises a casing, a rotary drum and a cover structure, and rotary drum is arranged in the outer casing. The inner wall of drum is covered with a centrifugal filter cloth, and the bottom of drum is assembled on power shaft. The lower end of power shaft is provided with a driven wheel. The driven wheel is connected to the driving wheel through a belt, the driving wheel is assembled at the output end of motor. The centrifugal liquid pipe is arranged at the bottom of casing, and the centrifugal liquid pipe is connected to the waste liquid tank through first water pump. The top of stationary tank is provided with supernatant liquid pipe connected to a supernatant liquid tank (3) through second water pump. USE - Industrial grade device for purifying graphene oxide solution. ADVANTAGE - The device can purify a large amount of graphene oxide solution by standing. The initial purification, supernatant is removed. The purification can be carried out continuously, and the purification effect is excellent, convenient and quick. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the industrial grade device. Static tank (1) Waste liquid tank (2) Supernatant tank (3) Waste liquid tank (4) Third pump (5)
