NOVELTY - The utility model claims a graphite oxidation reaction kettle for graphene production, comprising a kettle body, the side wall of the kettle body is orderly provided with a spiral heat exchange tube from inside to outside, a heating layer and an insulating layer; the kettle body is provided with a central shaft; the top end of the central shaft extends out of the kettle body and is in transmission connection with the third motor on the top part of the kettle body; the central shaft is provided with multiple stirring rods. The blanking plate of the utility model can prevent the graphite blockage, starting the third motor mixing the graphite and concentrated sulphuric acid uniformly, the oxidant barrel begins to discharge, potassium permanganate enters the discharging block, under the rotating action of the central shaft, spraying to the kettle body from the feeding hole uniformly, preventing local overheating, the spiral stirring paddle can make the material uniformly mixed in the vertical direction; when the reaction is finished, starting the telescopic cylinder, scraping the material on the inner wall of the kettle body; the spiral heat exchange pipe can be filled with circulating cooling water, or introducing heat conducting oil and using the heating layer to heat the heat conducting oil, so as to provide different reaction conditions for the reaction.
