▎ 摘　　要

NOVELTY - The system has a storage tank (1) for placing emulsified and to-be-filtered graphene slurry. An outlet of the storage tank is connected with an inlet of a filtering device (2). An outlet of the filtering device is connected to an inlet of a material pumping device (3), where an outlet of the pumping device is connected to an inlet of a material receiving tank (4). The storage tank is rotatably provided with a rotating impeller at a position of an outlet peripheral side. An outlet of the storage tank is located opposite to an eccentric position of the rotating impeller. A connecting piece is formed as a hollow ball shaped structure. The connecting piece is provided with a feeding port (6) and a discharging port (7) USE - Graphene slurry filtering system for use in an ultra-volume, lithium battery and photoelectric apparatus. ADVANTAGE - The system has effect of improving the quality of the graphene slurry product. The system can filter the graphene slurries by setting the storage tank, the filtering device, the material pumping device and the receiving tank after emulsifying, and improves product quality of graphene. The system can apply acting force of flowing graphene liquid to drive the rotating impeller to rotate for stirring the graphene liquid in a liquid tank, thus improving uniformity of the graphene liquid. The system prevents the graphene liquid from being dispersed, so that the graphene product quality is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a graphene slurry filtering system. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of the graphene slurry filtering system.
