▎ 摘 要
NOVELTY - Complete device of the utility model claims a light wave expansion stripping for preparing graphene, comprising oven, a cyclone collector and a draught fan, the light-wave oven comprises shell, one side of the shell is provided with a feeding port, and the other side is provided with a discharge port; the middle of the shell is equipped with a transparent tube, transparent pipe with one end connected to the inlet, the other end is connected with the discharge port, a transparent tube and the shell between a radiation lamp, a rotating shaft inserted in the shell and extends in the transparent pipe, the rotating shaft in the transparent pipe is fixedly connected with a plurality of stirring blade, the discharge port through the pipeline connected with the inlet of the cyclone collector, the discharge port position is provided with discharging valve, the air outlet of the cyclone collector through the pipeline connected with the air inlet of draught fan. Further, reflecting shade is set between the irradiation lamp and the shell; the rotating shaft is fixed with a spiral conveying blade, further pulse dust collector is set between the cyclone collector and a draught fan. The utility model can realize few layer graphene powder with low cost and large-scale production.
