▎ 摘　　要

NOVELTY - The device has a reaction kettle assembly (1), a suction filtration washing assembly and a drying assembly. The reaction kettle assembly includes a reaction kettle structure (101) that is provided with a first stirring medium extending into its interior, and an upper portion of the reaction kettle structure is provided with a silver nitrate feed port and an ascorbic acid feed port. A reaction outlet is provided at the lower portion of the reactor structure and connected to the suction filtration washing assembly. USE - Preparation device for graphene oxide composite ultrafine silver powder. ADVANTAGE - The device can effectively solve the problems of uneven preparation particle size, waste of energy, insufficient cleaning, waste of large amount of energy, and low production efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the preparation device for graphene oxide composite ultrafine silver powder.
