Description
Technical field
The utility model relates to the central cooler technology of metallurgical briquetting, sintering art, particularly bridging type sealing device between a kind of circular cooler trolley breast board and door type seal closure.
Background technology
The central cooler in the metallurgy sintered field of China is one of visual plant in its production technology, for heat of cooling sintering deposit, conventionally the cooling of central cooler is divided into some sections, the EGT that cooling section above produces is higher, is generally all recycled, along with central cooler fume afterheat utilizes the development of technology, how can guarantee that sintering deposit is normally cooling, central cooler equipment normally moves, and can reduce dust emission again, and high-temp waste gas is effectively collected.The trolley breast plate of central cooler motion and the fixedly sealing between cover play a part crucial.
Between the trolley breast plate of central cooler and cover, seal, have at present multiple hermetically-sealed construction, be roughly divided into contact and contactless two kinds of structures: 1) contact is generally the contact seal of the flexible pieces such as rubber or composite and rigid member composition; 2) contactless general on cover fixing seal plate insert in the ring-type cell body on trolley breast plate, in cell body, generally put into water or other solid granular media.
More typical flexible sealing material is rubber composite.Problem: (EGT of central cooler high temperature is generally 300 because elastomeric material cracky, heat resistance are not enough
0c-400
0c), often initial stage sealing effectiveness still can, long-term operation is leaked serious, up to 30%-50%, a large amount of heat energy is lost in air in vain, has lowered the efficiency of UTILIZATION OF VESIDUAL HEAT IN, in company with the dust shedding, has also polluted surrounding environment.Composite seal intensity and wearability are all better than rubber, but leak out in order to prevent, hermetic resistance is larger, and plant capacity consumption increases.Other is as adopted steel brush, although the better poor flexibility of heat resistance is difficult for after distortion recovering, and has gap between brush silk, sealing effectiveness is also undesirable.In addition with the seal form of elastomeric spring mechanism, its complicated structure, maintenance cost is too high.
