Abstract

A sealing device for a well type furnace opening comprises a furnace cover cooling cavity, a furnace cover sealing ring, a Muffle guide groove, a sealing ring, a Muffle cooling cavity, a furnace cover and a Muffle furnace body, and the furnace cover cooling cavity is fixed on the top face of the furnace cover. The furnace cover sealing ring is fixed on the edge of the bottom face of the furnace cover, and the Muffle cooling cavity is fixed on the outer side of the top end of the Muffle furnace body. The Muffle guide groove is fixed on the top face of the Muffle cooling cavity, and the sealing ring is fixed between the furnace cover sealing ring and the Muffle sealing groove. According to the sealing device for the well type furnace opening, the sealing ring is squeezed and deformed through the pressure of the oblique face of the furnace cover sealing ring and the positioning function of the Muffle guide groove, the sealing effect is enhanced, and the deformed shape of the sealing ring is used for completely sealing the furnace body and the furnace cover. The operation problems that the contact face of original plane sealing is small, the sealing face can be polluted easily and sealing is not accurate are solved, and the reliability and the safety of sealing of equipment are effectively improved.

Description

technical field [0001] The patent of the present invention relates to high-temperature sealing technology, specifically refers to the sealing technology of pit furnace mouth. Background technique [0002] During the operation of the well-type furnace, the furnace cover needs to be frequently opened to lift workpieces, and a tight and precise sealing device is required between the muffle and the furnace cover. In the past, the sealing device used the round steel on the furnace cover surface to be pressed into the packing structure on the muffle surface. Due to the small contact surface and shallow pressing depth, the furnace cover is often not tightly sealed, so that air may enter the muffle In the furnace body; the gas in the furnace is harmful to the operator and the environment, and the leakage of the furnace gas seriously affects production safety. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing...
