NOVELTY - The utility model claims a stirring device for preparing graphene, comprising a working table and a shell, wherein the shell is provided with a motor; the output end of the motor is fixedly connected with a sleeve; the sleeve is slidingly connected with a connecting rod; one end of the connecting rod far away from the sleeve is fixedly connected with a threaded rod; the threaded rod is fixedly connected with a spiral blade; one end of the threaded rod far away from the connecting rod is in threaded connection with a threaded sleeve; the threaded sleeve is fixedly connected on the shell and extends to the working table; between the working table and the shell is fixedly connected with a supporting plate. The utility model is added with material through the feeding hopper, adding organic solvent through the liquid inlet pipe, then starting the heating plate and starting the motor, so that the sleeve rotates along with the rotation of the motor, so that the spiral blade rotates, the threaded rod moves downwards, then controlling the motor to rotate reversely, so that the threaded rod rotates at the same time to move upwards, the spiral blade is driven to move upwards.
