NOVELTY - The utility model claims a reactor structure for microwave reduction expansion producing graphite alkene, comprising a reaction furnace tube, a feeding mechanism and an air inlet pipe; the feeding mechanism comprises a feeding pipe; the first valve and the second valve, the feeding pipe is connected with the reaction furnace tube, setting of the first valve and the second valve at intervals up and down on the feeding pipe, the first valve, the second valve and a feeding pipe is surrounded by a chamber, the air inlet pipe is connected with the storage chamber; the air inlet pipe is provided with an air inlet valve. The utility model, in the process of feeding, the first valve and the second valve not turned on at the same time, firstly opening the first valve so that the material enters the chamber, opening the air inlet valve, discharging the air in the storage chamber, closing the first valve and opening the second valve to make the material quickly into the reaction in the furnace pipe under the action of the gravity and blowing to realize fast feeding, at the same time, it can avoid the air feed pipe into the reaction furnace tube.
