Sealing device for heat and tail parts of air bellow of metallurgic sintering machine

Abstract

The invention relates to a sealing device for heat and tail parts of an air bellow of a metallurgic sintering machine. The sealing device comprises a plurality of key type sealing plates arranged on the lower surface of a trolley beam, spring mounting grooves are arranged in the lower ends of the key type sealing plates, a bottom plate is connected below each key type sealing plate by a guide positioning pin, pushed high temperature resistant springs are arranged between the spring mounting grooves and the bottom plates, and when the lower surface of the trolley beam where the key type sealing plates move is uneven, the key type sealing plates automatically push against the lower surface of the trolley beam under actions of the high temperature resistant springs, such that a fit clearance is reduced. B using the high temperature resistant springs to adjust the heights of the key type sealing plates, the sealing device can better adapt to the unevenness of the lower surface of the trolley beam, and the fit clearance between the key type sealing plates and the trolley beam is reduced, therefore, leakage of negative pressure wind is effectively reduced, the problems of a wind infiltration rate in sealing of the head and tail parts caused by deformation of a trolley of the sintering machine can be effectively solved, and the yield and quality of the sintering machine can be further improved.

Description

technical field [0001] The invention relates to a metallurgical sintering machine, in particular to a sealing device for the head and the tail of the bellows of the metallurgical sintering machine. Background technique [0002] The quality and efficiency of sintering machine production in the metallurgical industry are the key to the production of pig iron. The main factor determining the quality and output of the sintering machine is the air infiltration rate of the sintering machine. Reducing the air infiltration rate can directly improve the output and quality of the sintering machine. The main element and component to control the air seepage rate is the sealing device. At present, the sealing device of the sintering machine is mainly installed in the following parts: between the trolley and the bellows slideway, the head and tail of the bellows, and the joints of the flanges. Asbestos gaskets or asbestos rope seals, bellows head and tail seals are mainly used to seal the...
