▎ 摘　　要

NOVELTY - The device has a convex portion (33) i.e. U-shaped structure, arranged in two sides of an outer wall of a rotating rod (31) and fixed on two sides of a rotating blade (32). An outer wall of the convex portion is rotatably arranged with a shaft sleeve (34). A connecting shaft (35) is connected between the shaft sleeve and a baffle plate (30) through a hinge. An inner wall of a pipeline (10) is connected to a guide ring through a bolt, where the guide ring is located at a right side upper end of a blocking mechanism (23). USE - Graphene solution purifying device. ADVANTAGE - The device can block graphene solution so as to improve purification effect of the graphene solution and prevent large amount of the graphene solution to converge in an inner side of a rotating plate caused by large pressure, thus reducing rotation speed of the rotating plate, and hence reducing influence to centrifugal purification of the graphene solution. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene solution purifying device. 23Blocking mechanism 30Baffle plate 31Rotating rod 32Rotating blade 33Convex portion 34Shaft sleeve 35Connecting shaft
