▎ 摘　　要

NOVELTY - The device has a first dispersion tank (1), an activation reactor (2), a first filtration washing tower (3), a second dispersion tank (4), a reaction kettle (5), a second filtration washing tower (6), a third dispersion tank (7), a drying tower (8), a first storage tank (9) and a second storage tank (10) that are sequentially connected. The first filter washing tower, the first storage tank and first dispersion tank are connected in sequence. The second filter washing tower, the second storage tank and the second dispersion tank are sequentially connected. A high shear emulsifier and an ultrasonic disperser are simultaneously provided in the first dispersion tank, second dispersion tank, and third dispersion tank. USE - Macro-preparation device for carboxy functionalized graphene. ADVANTAGE - The device has a simple and compact structure, reasonable design, high degree of continuity and low equipment investment, and can efficiently prepare carboxy functionalized graphene and reduce production cost. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the Macro-preparation device.
