Description

A kind of liquid sealing blowing circular colling machine

Technical field

The present invention relates to a kind of metallurgical equipment, specifically a kind of liquid sealing blowing circular colling machine.

Background technology

In metallurgical process, with the matching used heat sinter cooling device of sintering machine, be commonly blowing circular colling machine.the schematic cross-section that is circular layout of existing blowing circular colling machine as shown in Figure 1, comprise theair blast 1 that is tightly connected in turn, blast pipe 2, circular loopedduct 4a,discharge pipe 5, wherein the outlet ofdischarge pipe 5 is passed the center of an annular water tank 6 and the entrance point of chassis induced duct 7 is tightly connected, the port of export of chassis induced duct 7 connects chassis 8, chassis 8 is arranged on central cooler framework 3, central cooler framework 3 is the slewing frame of an annular, in production reality, many chassis 8 just are arranged on the annular region that forms around central cooler framework 3 on this annular slewing frame and do gyration.Existing 420m for example²The liquid sealing blowing circular colling machine is to be 420m²The hot ore deposit cooling device that sintering machine is supporting, this cooling device mainly is comprised of slewing frame, drive unit, blower system, charging gear, device for discharging, watertight sealing groove ducting system etc., central cooler forms end to end annular solid by 64 chassis by the profiled beam on the slewing frame in the interior outside, rely on two groups of friction plates on friction pulleys driving slewing frame, make it along annular horizontal rail, make circular motion.

Traditional old-fashioned central cooler is unloading mining area part in addition, and its chassis bottom is the annular bellows of a connection.The grate plate that the cold air of whole bellows sees through each chassis is blown into the sintering ore bed on grate plate, makes it cooling.All chassis of annular bellows and top thereof form the cooled region of an integral body.Existing New sealing blowing circular colling machine has been cancelled trolley grating plate and directly has been communicated with the structure of annular bellows, as shown in Figure 2, the substitute is the double-decker that chassis is designed to chassis upperstrata grate plate 84 and chassis lower floorflat board 85, be provided with the profiled beam structure on chassis upperstrata grate plate 84, profiled beam comprises profiled beamdeck grate plate 86 and the profiled beamroof base plate 88 by the triangular shape of profiledbeam body 89 supportings; And the chassis sealing plate is equipped with in the left and right of the front and back of double-deck chassis next-door neighbour's profiledbeam body 89, between sealing plate and profiledbeam body 89 lower ends and chassis flat layer, staticseal rubber strip 10 is housed.Form like this quad seals space of a sealing between the doubling plate of chassis under the encirclement of above-mentioned parts, namely as a chassis sealing unit.Chassis induced duct 7 is introduced sealing unit from chassis inner sealplate air inlet 87 with cold wind, and cold wind blows to the sintering deposit bed of material 9 of grate plate top again.With respect to the whole coolant seal space of traditional central cooler, the coolant seal space is broken down into one by one independently chassis sealing unit in present technology.Overcome traditional central cooler integral body making, in installation process owing to there being error, by the time this error after operation of going into operation very easily causes the chassis in the sealing rubber strip passive movement of whole coolant seal to tear, strengthened the inleakage of central cooler, affect cooling effect, increasing energy consumption, cause simultaneously the working site dust large, contaminated environment and harm staff's health.

but, present this liquid sealing blowing circular colling machine is in the production run process, defect due to the static seal structure of the storage ash bucket of circular cooler trolley body bottom, make its adverse circumstances that can't adapt to production scene (be mainly the variation of alternating temperature-changing and to the extruding repeatedly of static seal rubber strip 10), and cause a large amount of graininess sintering deposits to be blown out by high-pressure blast from circular cooler trolley bottom storage ash bucket, the accumulation of being scattered in the annular section both sides of chassis operation, the operation of staticseal rubber strip 10 is changed in increase by forced-stopping machine, seriously restricting the normal operation of circular cooler trolley, and contaminated environment.

Summary of the invention
