Description
Technical field
The present invention 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 gate 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, usually 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 ensure that sintering deposit normally cools, central cooler equipment normally runs, and can reduce dust emission again, effectively be collected by high-temp waste gas.Sealing between the trolley breast plate of central cooler motion and fixing cover plays a part key.
Seal between the trolley breast plate of central cooler and cover and have multiple hermetically-sealed construction at present, be roughly divided into contact and contactless two kinds of structures: 1) contact is generally the contact seal that the flexible piece such as rubber or composite and rigid member form; 2), in contactless general ring-type cell body on cover on fixing seal plate insertion trolley breast plate, water or other solid granular media in cell body, is generally put into.
More typical flexible sealing material is rubber composite.Problem: because of elastomeric material cracky, (EGT of central cooler high temperature is generally 300 to heat resistance deficiency
0c-400
0c), often initial stage sealing effectiveness still can, longtime running leaks serious, and up to 30%-50%, a large amount of heat energy is lost in air in vain, reduces the efficiency of UTILIZATION OF VESIDUAL HEAT IN, also pollutes surrounding environment in company with the dust shed.Composite seal intensity and wearability are all better than rubber, but leak out to prevent, and hermetic resistance is comparatively large, and plant capacity consumption increases.Other is as adopted steel brush, although heat resistance better poor flexibility, not easily recover after distortion, and have 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.
The water-stop of non-contacting seal, due to good sealing effect, highlights its sealing advantage.Weak point is the boiling point of EGT herein higher than water, there is potential safety hazard.Add a set of plumbing and sewage disposal system in addition, regularly remove deposition wet silt material in the sink, by space constraint, operation and maintenance are all very difficult.The sealing of graininess sealing medium generally adopts sand seal, the degree of depth by the restriction seal groove of structure is limited, if it is improper that the fan delivery of sintering deposit cooling procedure and blast adjust, the pressure of waste gas is excessive, the resistance that the sand piled up produces is not enough to resist exhaust gas pressure, will sand be blown away, make the inside and outside UNICOM of cover, do not have sealing function on the contrary.
