Description
Technical field
The present invention relates to mineral hot furnace industry accessory, is specially a kind of explosion-proof dress of mineral hot furnace bell with auto-reset function
Put.
Background technology
Closed submerged stove in smelting process, when the material that occurs collapsing, turn over the problems such as slag when, the gas pressure in burner hearth can be unexpected
Increase, at this time, if not in time discharging pressure, can set off an explosion and cause the accident.And the material that collapses, turn over the problems such as slag and cannot keep away completely
Exempt from, relief hole, the explosion-protection equipment of respective numbers are must be provided with the bell of mineral hot furnace, can when gas pressure exceedes safety value
With the decompression cover of explosion-protection equipment is open-top, pressure release is realized.
In the prior art, explosion-protection equipment operation principle mainly has three kinds of forms：
1st, decompression cover is welded on bell with loop chain, and during pressure release, decompression cover is flicked, or even flown by bullet, and furnace charge splashes, and is needed
Manually Explosion-proof cap to be resetted or welded；
2nd, decompression cover and the stud connection being welded on bell, during pressure release, decompression cover is around hinge shaft Unscrew, by pressure release
Lid gravity is realized and automatically reset, but furnace charge easily splashes；
3rd, decompression cover can rise along outer wall, and venting pressure is adjusted by clump weight, but during pressure release, decompression cover easily with
Outer wall disengages, and furnace charge splashes, it is impossible to which realization automatically resets；
In pressure release, furnace charge splashes the bell explosion-protection equipment of the above-mentioned prior art, decompression cover is flown by bullet, all may be to periphery
Personnel, equipment, environmental pollution, there is very big security risk, it is necessary to manually answer relevant device after the completion of pressure release
Position, influence to smelt is carried out continuously.
Therefore a kind of mineral hot furnace bell explosion-protection equipment with auto-reset function is developed in market in urgent need.
The content of the invention
The object of the present invention is to provide a kind of simple in structure, safe and reliable, can prevent furnace charge splash and realize from
The dynamic bell explosion-protection equipment resetted.
