NOVELTY - The purpose of the utility model is difficult to solve the problem of not easy to fully screen the graphene, claims a graphene sieving device, comprising a top rod, a first rotating shaft, a first gear, a first motor, a chain, a holding ring, a supporting block. a supporting rod, a locating ring, a sleeve ring, a mounting plate, a connecting rod, a thin plate, a push plate, a spiral spring, a locating rod, a connecting plate, a mounting rod, a second motor, a turntable, a first rack, a second rack, a sliding rod, a guide pipe, a supporting plate, an observation window, a base, a first end cover, a containing box, a heating plate, a second rotating shaft, a connecting ring, a second end cover and the second gear. The utility model rationally uses the cooperation of the first electric motor and the second electric motor, in the case a material holding ring rotation using push to strike the material holding ring so as to effectively through the holding ring to graphene to sieve, combined drying of heating plate, preventing the mesh of the containing ring blockage, improves the sieving effect, and reasonable design, convenient operation, meets the demand of graphene field.
