NOVELTY - The utility model claims a graphene composite filter film, belonging to the technical field of environment-friendly new material, comprising a film body, the surface of the film body is provided with a plurality of convex blocks in circular shape, the lower end of the plurality of convex blocks are provided with a plurality of openings along the surface thereof, the inner top end of each convex block is provided with a supporting thin rod, and the supporting thin rod are adhered with the convex block through glue; the left and right ends of each supporting thin rod are provided with an iron screw rod, and each iron screw rod is fixedly connected with the supporting thin rod, one side of each iron screw rod biased to the convex block is provided with two supporting blocks, and each supporting block is fixedly connected with the iron screw rod, the inner middle end of the film body is provided with a first filter screen. The graphene composite filter film is additionally provided with a plurality of convex blocks on the surface of the film body, which can reduce the direct impact of the solution to the film body, so that the solution can pass through the plurality of openings at the edge of the lower end of the convex block and flow through the film body, dispersing the filtering amount, which improves the stability of the film body in a certain degree.
