▎ 摘　　要

NOVELTY - The device has a puffing furnace (1) and a receiving bin (5) that is provided at the lower end of the puffing furnace. A furnace cover (10) is provided on the upper end of the puffing furnace. An exhaust pipe (2) is provided on the upper surface of the furnace cover. A feeding hopper (3) is provided at one end of the puffing furnace. A control panel (11) is provided on one side of the lower end of the feeding hopper. An organic shell (4) is provided at one end of a driving motor (12). A heat preservation cavity is opened inside the puffing furnace. A heater is arranged inside the heat preservation cavity. The inside of the heat preservation cavity is located outside the heater, and a first circulation pipe is provided. An inner bucket is arranged inside the feeding hopper. A preheating cavity is arranged between the feed hopper and the inner hopper, and a second circulation pipe is arranged inside the preheating cavity. USE - Graphene continuous microwave expansion device. ADVANTAGE - The graphene continuous microwave expansion device utilizes the high-temperature gas generated during the expansion of the material, which has the effect of insulating the expansion furnace, and avoids the problem of heat loss caused by the large temperature difference between the inside and the outside of the expansion furnace, and can recover the heat of the expanded high-temperature material. The recovered heat is pre-heated to the puffed material, and the double-sided effect makes the processing effect of the graphene material better, and reduces the waste of heat. The exhaust gas can be subjected to secondary purification to prevent harmful dust or impurities in the gas from being discharged into the air and affecting environmental quality or harming human health. The design is simple and convenient, and has a high energy recovery rate and guarantees the expansion of materials effect.
