NOVELTY - The utility model claims a graphene heating insulating sleeve for chemical production device, belonging to the technical field of graphene insulating sleeve, to solve the problem that the current graphene heating insulating sleeve is sleeve pipe in temperature balancing speed after heating, and the placing time is too long to cause graphene oxidation, comprising a supporting seat, a fixing ring, sleeve pipe outer wall, a sealing cover, graphite cylinder and a locking cover; the sleeve pipe wall is set on the upper part of the supporting seat; the fixing ring is fixedly connected to the outer ring of the outer wall of the sleeve pipe the sealing cover screw thread connected to the left end of the outer wall of the sleeve pipe the graphite part of the outer wall sleeve pipe the outer wall is provided with an inner side; the locking cover is set at the right end of the graphite cylinder, the utility model through the heating sheet is completely jointed on the inner wall of the sleeve pipe to make the temperature transfer more uniform, effectively reduce the temperature equalization time of the insulating sleeve, the graphene in the cylinder graphite kept dry by the drying pipe, which effectively reduces the oxidation, improves the utilization rate of the graphite, so as to reduce the material cost.
