NOVELTY - The utility model belongs to the graphene of production equipment, claims a graphene powder mixing device, comprising: A tank body, comprising: a powder feeding piece with downward outlet, a valve body set in the powder feeding piece, two first stirring blades transversely stirring in the tank body, a second stirring blade vertically set under each first stirring blade, a first motor and a second motor rotating along the axial direction, and a first motor and a second motor respectively driving the first stirring blade and the second stirring blade to rotate. The graphene powder mixing device of the utility model, through setting outlet downward powder feeding piece, directly feeding the graphene powder in the solution, making it not directly floating on the solution surface because of the density problem, then through stirring, making it fully fused with the solution, so as to solve the problem that the powder density is small, resulting in graphene powder floating on the solution, cannot be fully mixed with the solution of the technical problem.
