NOVELTY - The utility model claims a modified preparation device for graphene production, relating to graphene field, comprising a base, the top part of the base is provided with a preparation cylinder, the top part of the preparation cylinder is connected with a stirring component through a control motor, the top part cylinder is uniformly provided with a plurality of groups of drivers, the output end of the driver passes through the preparation cylinder and is connected with a hose, and one end of the hose is connected with several groups of vibrating rod head, the vibrating rod head is set around the stirring component. The utility model drives the stirring blade to stir the solution in the preparation cylinder by controlling the action of the motor, the mixing with the vibrating rod makes the inner stirring more fully, the solution after the reaction is prepared and exchanged with the solution in the centre of the preparation cylinder through the action of the vibrating rod, so as to improve the preparation efficiency of the graphene in the preparation barrel, and reduce the preparation cost of the graphene in the preparation barrel.
