▎ 摘　　要

NOVELTY - The ingredient device comprises a base and a mixing reaction cylinder. The dosing device has two solvent metering structures (3), which are symmetrically fixed on the top end of the mixing reaction tube. Each of the solvent metering structure has a supporting rod (31). A metering cylinder (32) is fixedly mounted on first side of the top of the supporting rod. A rubber plug (33) is movably assembled on the inner wall of the metering tube. The electric telescopic rod (34) is fixed between the rubber plug and the mixing reactor. A first electromagnetic valve (35) vertically passes through first side on the lower surface of the rubber plugs. USE - Dosing device for graphene of preservative for graphene processing ADVANTAGE - The dosing device has high controllability of metering adding, and provides high uniformity of mixing of ingredients, and can provide effect of full cleaning of the inner cylinder of the dosing devices, the functionality is more abundant. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of Dosing device for graphene of preservative for graphene processing.
