NOVELTY - The utility model claims a device for preparing multi-layer graphene, comprising a liquid storage tank, the top of the liquid storage tank is welded with shell of the cylindrical hollow structure, and the opening of the shell downwards; the inner ring welding shell with a circular first supporting plate. the inner ring of the movable sleeve of the first supporting plate is connected with the lower rotating wheel, lower outer ring of the rotating wheel is provided with a first supporting plate movably sleeved with limit groove and under the first supporting plate equipped with a first driving mechanism connected with the lower rotating wheel, one side of the first driving mechanism equipped with a first supporting plate is fixedly sleeved with a recycling pipeline; right above the first supporting plate is provided with a second supporting plate is fixed connected with shell inner ring. The utility model is structure simply convenient and quick operation, convenient raw material cut to collect, while adjusting the distance between the rotating wheel and the lower rotating wheel, so as to adjust the shearing force between the upper rotating wheel and the lower rotating wheel, suitable for the processing of graphene materials.
