A combined detachable movable smoke hood for an annular cooler

Abstract

The invention provides a combined detachable movable smoke hood of an annular cooler. The combined detachable movable smoke hood of the annular cooler comprises a trolley, a traveling platform and a movable smoke hood, wherein the movable smoke hood mainly comprises main framework columns, a frame beam, a movable baffle, a refractory lining, fasteners, buckles, sealing asbestos washers, springs, washers and hexagon nuts; a smoke hood body is mounted on the traveling platform of the annular cooler, hoods the trolley, and mainly comprises a main structural column, the frame beam and a movable baffle door; the refractory lining is arranged in the movable baffle; each fastener is provided with the corresponding buckle. The combined detachable movable smoke hood of the annular cooler has the advantages that the problem that the smoke hood of the annular cooler is short in service life is solved; the problem of sealing difficulty of the annular cooler caused by waste heat utilization is solved; the smoke hood body is fixedly arranged on the platform of the annular cooler, so that a chimney can be mounted on the smoke hood body; by virtue of a frame-baffle combination structure, a heat preservation layer can be replaced at any time on line when being disengaged; the smoke hood body is suspended over the trolley and hoods the trolley, so that the problem of sealing difficulty between the trolley and the smoke hood is solved.

Description

Technical field: [0001] The invention relates to the technical field of auxiliary equipment for sintering machines, in particular to a combined detachable movable fume hood for an annular cooler. Background technique: [0002] In the prior art, the sinter machine produces sinter to provide raw materials for the blast furnace. In order to ensure the quality of sinter ore and the safe operation of conveying equipment, it is necessary to use a cooler to forcibly cool the sinter ore, and a large amount of high-temperature flue gas is generated during the cooling process. A ring cooler is usually used for cooling, and the high-temperature part of the flue gas is collected through the fume hood, and then connected to the chimney to discharge the atmosphere. The cooling process is as follows: the high-temperature sintered material after the sintering charge is sintered in the sintering machine falls on the ring cooler, and is blown and cooled by the cooling fan, and the heated air...

AI Technical Summary

Problems solved by technology

The steel brush seal is deformed after long-term operation, the seal leakage is serious, the operating life is low, and maintenance is difficult; the elastic seal can achieve a better sealing effect, but in actual operation, due to the different control of each node of the upper-level process sintering or the operating level. Differences, under-burning usually occurs, resulting in high temperature of the blanking ore and even burning. In this case, the elastic seal, especially the high-temperature section seal, is easy to be burned. If there is no seal, the air leakage rate is very serious, so it is necessary to ensure The main process is in normal production, and the ring cooler will not stop production due to the burning of the sealing rubber, which will seriously affect the utilization of waste heat before the next maintenance
