NOVELTY - Device comprises breaking and dismantling reactor (1), discharge port (2), single acting pump (3), controllable valve (4), cylinder block (5), piston (6), piston shaft (7), sliding groove frame (8), swing rod (9), eccentric wheel (10), adjusting slot (11), distributing port (12) and settlement flat plate (13). The process of breaking down liquid carbon dioxide and graphite powder turbid liquid into liquid carbon dioxide and free carbon atom suspension comprises opening controllable valve, starting single acting pump, flushing residual liquid in outlet, pumping out liquid carbon dioxide free carbon atom suspension to sedimentation plate through discharge port to obtain graphene and pumping out liquid. USE - The device is used for preparing graphene from liquid carbon dioxide free carbon atom suspension. ADVANTAGE - The device has simple structure, easy program control, complete breaking process and balanced mixing and concentration of suspension in distribution process. The graphene products has same thickness and quality.
