Furnace body sealing structure of pot-type calcining furnace

Abstract

The utility model discloses a pot-type calcining furnace body sealing structure which comprises a base device, a top cover device is arranged at the top of the base device, and a sealing device is arranged at the bottom of the top cover device. The sealing device comprises two symmetrical second lifting frames, and second racks are fixedly arranged on the outer sides of the second lifting frames; according to the pot-type calcining furnace body sealing structure, the sealing design is achieved by blocking the gap through the air bag, the furnace body is automatically sealed through heat generated after the processing furnace is started, meanwhile, after processing is finished, the temperature in the furnace is lowered, the air bag shrinks, sealing is automatically relieved, and the sealing effect is good. Automatic operation is realized by utilizing the principle of gas thermal expansion without additional power, the automation degree of the device is improved, the device is simple in structure, and the manufacturing cost is reduced; and through the design of air bag plugging, the device can adapt to furnace covers of different sizes and machining furnaces of different sizes, the application range of the device is wider, and the universality of the device in the application occasion of the calcining furnace is further improved.
