Abstract
The utility model relates to a high boiler slag iron ditch seal cover, especially relates to a slag iron ditch seal mechanism for dedusting in a non-flat blast furnace casting field. The utility model principally resolves a technical problem that the existing seal mechanism is not capable of tightly sealing iron ditch and slag ditch covers. The technical project of the utility model is that an arched seal cover is arrange in the slag iron ditch, two sides of the slag iron ditch are all provided with leveling layers, each leveling layer is provided with a ditch side base, characterized in that a seal groove is embedded between the ditch side base and the external side wall of the slag iron ditch, the seal groove is filled with grit, the bottom of two sides of the arched seal cover is provided with a corner seal piece, and the lower edge of the corner seal piece is inserted into grit. The utility model is principally used for preventing cast house soot dust from being discharged outside, and providing a well station entironment.
Description
Technical field
The utility model relates to blast furnace slag iron runner seal closure, particularly a kind of non-flat forms blast furnace discharge yard dedusting slag iron runner sealing mechanism.
Background technology
Steel industry is high energy consumption, heavy polluted industry, operation before iron especially, and the total amount of pollutant that sintering, blast furnace operation produce is very big.In recent years, along with the day by day strictness of country to environmental requirement, steel industry is to the application pay attention to day by day of green technology both at home and abroad, and a large amount of electrostatic precipitator, sack cleaner etc. are applied in each dust-removal system of steel industry, and the emission concentration of chimney has obtained effective control.But the tobacco powder dirt capture rate of producing dirt pits is not high always, and the on-the-spot tobacco powder dirt that produces can not effectively be siphoned away, and causes on-the-spot airborne dust serious.
2000m
3Following blast furnace, the field structure that taps a blast furnace is generally tilting, blast furnace is in the process of tapping a blast furnace, molten iron flow through skimmer, iron runner and slag runner, the pyritous molten iron contacts with iron runner castable, to produce volume of smoke, but owing to needing to observe the reasons such as molten iron mobility status that iron runner etc. is located in the process of tapping a blast furnace, the covered and enclosed cover can't be realized always on slag runner and the iron runner, even enclosed hood is installed sometimes, but because the tilting structure of casting house causes reasons such as enclosed hood can't be located, structure imprecision to cause volume of smoke excessive.
Chinese patent CN200320128216.3 discloses " energy-saving iron runner, slag runner complex protection cover plate ", and its feature relates to energy-saving iron runner, slag runner complex protection cover plate.Its exhaust emission at iron runner, slag runner position that solves present blast furnace is big, and that temperature reduces is fast, hang complexity, labour intensity is big wait not enough.The technical measures that solve: comprise camber or bend the shaped metal plate, it is to be fixed with stiffening web in the metal sheet inboard, is cast with the cast bed of material in the slit between metal sheet and stiffening web, at the internal surface of pouring into a mould the bed of material hyperthermia radiation layer is arranged.Its advantage be to reduce waste gas to pollution, the high insulating effect of environment, be convenient to install and in light weight.By at mould material surface-coated high temperature radiating coating material, can reflect the heat of molten iron, play energy-saving effect.Be welded with stiffening web on the iron plate, for reduce mould material to come off, improve work-ing life favourable.Its not only suitable large blast furnace is also suitable to medium and small blast furnace.Major defect is the sealing problem that does not have effectively to solve iron runner and slag runner operculum colpi.
The utility model content
The purpose of this utility model provides a kind of non-flat forms blast furnace discharge yard dedusting with slag iron runner sealing mechanism, mainly solves the technical problem that existing sealing mechanism can't be realized the sealing of iron runner and slag runner operculum colpi.
The technical solution of the utility model is: a kind of blast furnace discharge yard dedusting slag iron runner sealing mechanism, on the slag iron runner, settle an arch seal closure, be provided with screed-coat in slag iron runner both sides, ditch group pedestal is installed on screed-coat, it is characterized in that: between ditch group's pedestal and slag iron runner outer side wall, embed a sealing groove, fill up sand grains in the sealing groove, on base, arch seal closure both sides a turning diaphragm seal is set, insert in the sand diaphragm seal lower edge, described turning.
Be welded with stiffening web at turning diaphragm seal and arch seal closure junction, pile up the ditch of piling up that has with turning diaphragm seal level in slag iron runner upper edge and help, on the arch face of arch seal closure, have handle hole, settle hanger on arch seal closure top.
The beneficial effects of the utility model: adopt reliable locating device and effective draw-in groove seal style, can guarantee that slag, iron runner enclosed hood be not because of reinstalling the deviation that causes the installation site, the problem that reduces sealing effectiveness after the maintenance, pass through the handle hole of design simultaneously, satisfy in the process of tapping a blast furnace, the workman is to the needs of pulp water and molten iron operation in slag runner and the iron runner, promptly guaranteed the sealing effectiveness of enclosed hood, satisfied the needs of production operation again, can not bring any inconvenience to production.Simultaneously, more can guarantee the post environment that casting house is good, help the healthy of worker.Therefore has the excellent popularization prospect.
