Description
Technical field
The invention belongs to sintering or cooling device technical field in smelting industry, particularly relate to a kind of technology utilizing the difference of the pressure outside inner bellows and bellows to seal gap between chassis and bellows.
Background technology
In iron and steel is produced, SINTERING PRODUCTION is one of important operation, and it provides the raw material of high-quality for blast furnace ironmaking.In existing sintering system, chassis is positioned at above sintering machine wind box, run on the trolley track of bellows both sides after chassis being filled compound, light a fire at compound top through ignition furnace, bellows are at chassis downdraft, compound is sintered downwards by the top of chassis, in order to the exhausting effect making bellows reach good, must ensure there is reliable sealing between sintering machine wind box and chassis, it is the least possible not produce leaking out of leaking out or produce.Reducing that sintering leaks out is Focal point and difficult point in sintering process design and production maintenance, owing to there is gap between chassis and chassis and between chassis and bellows, leak out serious, even reach more than 50%, not only waste energy, form noise pollution environment, and limit the raising of SINTERING PRODUCTION efficiency and affect product quality.
The sealing majority of traditional chassis and sintering bellows adopt the elasticity being arranged at pallet bottom to swim mode that plate contacts with the slideway being arranged at bellows both sides is to carry out the sealing of chassis both sides, the contact surface great majority of trip plate-chute type sealing are flat, rely on the pressure of spring above trip plate, upper and lower two planes are contacted with each other when relative sliding and realizes sealing, in use, in order to reduce the frictional resistance between elasticity trip plate and slideway, generally on ground way, establish oil groove, the high temperature resistant butter of continual injection is carried out by electric dry oil pump, residing for bellows, environment temperature is high, the butter dehydration of filling is easily caused to become dry, be unfavorable for the filling of butter and the lubrication of slideway, and in chassis running, sintering raw material and grog are easy to again be bonded on elastic slideway, elastic slideway is ground, damage, there is leaking out gap, cause a large amount of leaking out, the reactance capacity of Sinter air machine is increased, and easily cause sintering time to extend, even sintering finished rate reduces, sintering output declines.Simultaneously because slideway sealing adopts the form of hard sealing, in car puller or chain belt machine running, add running resistance, more accelerate the wearing and tearing of elastic slideway, encouraged the possibility of leaking out.Because its Air Leakage cannot solve, therefore traditional sintering only has and strengthens the exhausting amount of Sinter air machine to ensure sintering output, causes so again sintering power consumption and operating cost, the significantly improving of maintenance cost.
In order to solve the problem, applicant devises the side-sealing device between a kind of chassis and bellows, Chinese Patent Application No. is 201110030113.2, the sealing device of this chassis and bellows comprises: the sealing plate being arranged at position, chassis lower outside face and the sealing plate installation component be installed on by sealing plate on the mounting bracket being located at bellows top outer, sealing device adopts the mode sealed from the side, utilize the negative-pressure adsorption sealing plate formed during bellows exhausting, the gap between pallet bottom and bellows top is sealed.Although side seal can overcome the deficiency that in traditional trip plate-slideway upper-lower compacting hermetically-sealed construction, seal is easy to wear, leak out low, improve air quantity utilization rate, but because sealing plate is mounted in sintering machine wind box top, rely on sealing plate side and chassis contacts side surfaces to realize sealing, but the sealing effectiveness between sealing plate top and chassis bottom surface is not good.
