NOVELTY - The utility model is suitable for graphene oxide technology field, claims a filter aid for preparing graphene oxide process, comprising a base, the upper surface of the base is fixedly connected with box body, the upper surface of the box body is provided with an annular sliding groove; the inner part of the annular sliding groove is clamped with two sliding blocks matched with the annular sliding groove; the upper surface of the box body is provided with a through hole; the upper part of the box body is provided with a threaded rod, the bottom end of the threaded rod passes through the through hole and extends to the inner part of the box body. The filtering auxiliary device for preparing graphene oxide process, the power generated by the motor, the connecting rod drives the driving belt pulley to rotate, then using the matching of the belt and the secondary belt pulley, driving the thread cylinder to rotate, and making use of the threaded rod of the screw thread cylinder, driving the mixing blade to rotate and move up and down; so as to uniformly mix the graphite powder and the chemical agent, at the same time, increasing the reaction speed, avoiding increasing the filtering time of the graphene oxide.
