The technical scheme solved the problems of the technologies described above is:
A kind of ring cold machine smoke hood sealing device, it comprises skirt plate rack, sealed skirt sheet, skirt plate rack is connected with petticoat pipe, sealed skirt sheet is connected to the outside of skirt plate rack, its improvements are, sealed skirt sheet is stainless steel skirt sheet, increase skirt sheet fixed head in the outside of sealed skirt sheet, upper end and the skirt plate rack of skirt sheet fixed head are welded to connect, and set bolt is fixedly connected with skirt plate rack through skirt sheet fixed head, sealed skirt sheet.
Above-mentioned ring cold machine smoke hood sealing device, the top of described skirt plate rack is level board face, and one end and the petticoat pipe in level board face are welded to connect, and the bottom of skirt plate rack is the side plate of downward 90 degree of bendings, and the side of sealed skirt sheet is adjacent to the outside at side plate.
Above-mentioned ring cold machine smoke hood sealing device, the plate face of described skirt sheet fixed head is the plate face of 90 degree of bendings, one end of the upper end horizontal plane of skirt sheet fixed head and the level board face on skirt plate rack top are welded to connect, the plate face vertically downward of skirt sheet fixed head is positioned at the outside of sealed skirt sheet, skirt sheet pressing plate is placed with between the plate face vertically downward and sealed skirt sheet of skirt sheet fixed head, skirt sheet pressing plate press seal skirt sheet, set bolt is fixedly connected with skirt plate rack through skirt sheet fixed head, skirt sheet pressing plate, sealed skirt sheet.
Above-mentioned ring cold machine smoke hood sealing device, described sealed skirt sheet is multi-disc, multi-disc sealed skirt sheet overlaps along circular cooler trolley traffic direction when installing, at the centre position welding wire rope guide ring of the lateral surface of every sheet sealed skirt sheet, steel wire penetrating guide ring, the end of steel wire rope changes direction by fixed pulley, and the lower end of steel wire rope hangs weight and strained by steel wire rope.
The beneficial effects of the utility model are:
1. sealed skirt sheet of the present utility model changes stainless steel skirt sheet into by original alumina silicate fibre cloth or rubber seal, there is high temperature resistant, good springiness, on-deformable advantage, both solve easily coming off by temperatures involved is corroded aging of alumina silicate fibre cloth, solve again the problem scratching damage because of central cooler sideslip;
2. change original into set bolt by the mode of wedge block and wedge fixing seal skirt sheet, and install skirt sheet fixed head and skirt sheet pressing plate additional, make structure firmer, reliable;
3, sealed skirt sheet adopts the mode mutually overlapped along traffic direction, can prevent chassis sideslip from scratching;
4. tied by sealed skirt sheet surrounding steel wire rope, two ends add counterweight tension, make sealed skirt sheet be in the state contacted with circular cooler trolley sealing plate all the time, improve sealing effectiveness.
Adopt after the utility model, the service life that petticoat pipe seal brought up to more than 2 years by original 3 months, and minimizing petticoat pipe leaks out, and reduced and safeguard intensity.Because sealing effectiveness improves, make the flue-gas temperature of central cooler high temperature section bring up to 240 DEG C by original 220 DEG C, generated energy is increased to 170,000 degree/sky by original 150,000 degree/sky, for the economic benefit improving enterprise has made remarkable contribution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: skirt plate rack 1, side plate 2, skirt sheet fixed head 3, sealed skirt sheet 4, skirt sheet pressing plate 5, set bolt 6.
