▎ 摘  要

(CN214276515-U) NOVELTY - The utility model claims a bidirectional temperature control airtight sintering furnace, comprising: an outer furnace and an inner furnace; the lower part of the outer furnace is provided with a containing space capable of containing an inner furnace; and the inner furnace is sent to the inner part through a lifting device at one side; the outer furnace peripheral wall is a heat-resistant structure; the inner cloth is provided with a heating element and a temperature sensing rod; it can provide heating function and detecting instant temperature to the upper and middle area of the inner part; the inner furnace is provided with a trolley and covered with a sealing cover; the surface of the inner furnace is embedded with a heating element; the surface provides placing of each type of firing object; the lower part of the firing object is directly heated; and the central part is provided with a temperature sensing rod and an external gas supply device composed of an air inlet pipe and an exhaust pipe; to provide various gases input in the sealing cover corresponding to different firing objects; directly heating through the inner furnace at the lower part; providing the indirect heating effect of the upper part and the middle part when the inner temperature is not uniform or insufficient by matching with the outer furnace; the whole sintering furnace reaches the uniform temperature; the heating effect; by this, the quality of the product is improved.
