Abstract
The utility model discloses a kind of mineral hot furnace venting of dust explosion lid arrangement, belong to the safe explosion venting device of superpressure, be made up of venting of dust explosion lid, pitch chain etc.Venting of dust explosion lid embeds in the peripheral sealing groove of venting of dust explosion hole, tamps sealing with fire clay.When furnace inner gas pressure superpressure, venting of dust explosion cover drum in seal groove is opened, and opens venting of dust explosion hole, realizes pressure release in stove, cannot release and the problem that sets off an explosion when solving superpressure in stove.
Description
Technical field
The utility model belongs to the safe explosion venting device of superpressure, specifically a kind of explosion venting device carrying out safety relief when increasing suddenly for closed submerged stove furnace pressure.
Background technology
Closed submerged stove is because the working of a furnace is unstable in smelting process, and inner flue gas of the stove pressure is constantly fluctuation change.Occur turning over slag when suddenly, the phenomenons such as material of collapsing time, pressure in the burner hearth can moment sharply increase.Now, if fallen by earth pressure release not in time, pressure in the burner hearth superpressure will set off an explosion, and causes device damage and casualties.Mineral hot furnace, in smelting process, the material that collapses, is turned over slag phenomenon and cannot be avoided, and the possibility of therefore inner flue gas of the stove blast also cannot be avoided, and likely occurs at any time.How preventing the generation of explosion accident, ensure safety in production, is that mineral hot furnace produces the problem that always will solve.
Utility model content
The utility model solves an above-mentioned difficult problem, provide a kind of structure simple, seal tight, safe and reliable venting of dust explosion lid arrangement.
The technological means that the utility model adopts is as follows:
Mineral hot furnace bell is offered several venting of dust explosion hole, venting of dust explosion lid arrangement is installed outside hole.Venting of dust explosion lid outer embeds in the seal groove of venting of dust explosion hole periphery, and the interior fire clay of seal groove fills up tamping, realizes sealing.When furnace pressure superpressure, venting of dust explosion cover upwards drum is opened, and opens venting of dust explosion hole, realizes pressure release in stove.Fly up after opening for preventing venting of dust explosion lid drum and smash other equipment or personnel, venting of dust explosion lid pitch chain is fixed on bell.
The utility model is applicable on closed submerged stove and similar metallurgical industry furnace apparatus.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of a kind of embodiment of the utility model;
Accompanying drawing 2 is part drawings of the utility model venting of dust explosion lid;
1. venting of dust explosion lid, 2. pitch chain, 3. fire clay, 4. fixed heads in figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
The utility model detailed description of the invention is: the venting of dust explosion lid 1 outer ring ring flat-plate that cast form or Plate Welding are shaped embeds in the peripheral sealing groove of bell venting of dust explosion hole, tamps in groove with fire clay 3.Venting of dust explosion lid and bell seal groove are connected after fire clay solidification, sealing is tight, realizes bell airtight.When furnace pressure increases suddenly, the high pressure draught acted on venting of dust explosion lid bottom surface produces an impulse force upwards to venting of dust explosion lid, and venting of dust explosion lid upwards flies up, and is opened in venting of dust explosion hole, the pressure in stove is released fast, prevents explosion accident.Smash other equipment or personnel for preventing venting of dust explosion lid from flying up, venting of dust explosion lid pitch chain 2 is fixed on bell.
The utility model structure is simple, and processing and manufacturing is easy, and sealing is tight, safe and reliable.Mineral hot furnace equipment has used for many years, through checking very economical being suitable for, safe and reliable.
Claims (1)
1. mineral hot furnace venting of dust explosion lid, its technical characteristic is: be made up of venting of dust explosion lid, pitch chain, and venting of dust explosion lid embeds in the peripheral sealing groove of venting of dust explosion hole, and tamp sealing with fire clay, venting of dust explosion lid is fixed on bell fixed head by pitch chain.
