Abstract
The utility model discloses a kind of mineral hot furnace can automatic fall-back Explosion-proof cap device, belongs to the safe explosion venting device of superpressure, is made up of Explosion-proof cap, hinged-support, bearing pin, guide rod etc.When furnace inner gas pressure superpressure, Explosion-proof cap rotates around hinge, opens venting of dust explosion hole, realizes pressure release.After pressure release completes, Explosion-proof cap, under self gravitation and the effect of bearing bounce, can reset by automatic fall-back rapidly, again be closed in venting of dust explosion hole.Solving that Explosion-proof cap opens can not the problem that can not again close of automatic fall-back, venting of dust explosion hole.
Description
Technical field
The utility model belongs to the safe explosion venting device of superpressure, specifically a kind of safety relief and the explosion-protection equipment of closing that afterwards automatically resets 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 in burner hearth, flue gas pressures is constantly fluctuation change.Once occur turning over slag, the phenomenons such as material of collapsing, pressure in the burner hearth can sharply increase moment.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 burner hearth flue gas explosion also cannot be avoided, and likely occurs at any time.
At present, the explosion precaution that mineral hot furnace generally adopts is on bell, offer multiple venting of dust explosion hole, installs Explosion-proof cap.When pressure in the burner hearth increases suddenly, Explosion-proof cap can be held by drum, and furnace pressure is released through venting of dust explosion hole.Fly up after opening for preventing Explosion-proof cap drum and smash surrounding devices and personnel.Usually Explosion-proof cap pitch chain is fixed on bell.
This kind of explosion-protection equipment can prevent the generation of stove implode accident effectively, but its Shortcomings part: after venting of dust explosion, venting of dust explosion hole can not be closed by automatic fall-back by Explosion-proof cap again, venting of dust explosion hole is in open mode, extraneous air can enter rapidly in stove, and in stove, air-tight state is destroyed, and smelts and is forced to interrupt, need manually to close Explosion-proof cap one by one, re-start closed.If after venting of dust explosion, venting of dust explosion hole is closed by Explosion-proof cap energy automatic fall-back again, and burner hearth still can be in air-tight state, and smelt and just can proceed, the production of mineral hot furnace would not be affected.
Utility model content
The utility model overcomes the deficiency of above-mentioned explosion-protection equipment, provide a kind of structure simple, safe and reliable, can the Explosion-proof cap device of automatic fall-back.
The technological means that the utility model adopts is as follows:
Set up otic placode and hinge at Explosion-proof cap sidepiece, Explosion-proof cap can rotate around hinge, and Explosion-proof cap changes rotary type opening and closing into by the formula opening and closing of moving up and down.When in stove during superpressure, Explosion-proof cap sways, and opens venting of dust explosion hole, realizes pressure release.After pressure release completes, Explosion-proof cap, under self gravitation and the effect of bearing bounce, can fall reset after rise rapidly, again be closed in venting of dust explosion hole.Establish arc guide rod, Explosion-proof cap slides along guide rod simultaneously, and when ensureing to rotate, position does not accurately misplace.
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 Explosion-proof cap;
1. Explosion-proof caps, 2. bearing pin, 3. hinged-support, 4. guide rod, 5. spring 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: Explosion-proof cap 1 end face that cast form or Plate Welding are shaped, with otic placode, otic placode is with pin shaft hole.Fixed-hinged support 3 is welded on bell end face.Explosion-proof cap bearing pin 2 is fixed on hinged-support, can rotate around bearing pin.Explosion-proof cap outer ring ring flat-plate inserts in the peripheral sealing groove of bell venting of dust explosion hole, and the interior fine sand of groove tamps, and realizes sealing.When furnace pressure increases suddenly, the gases at high pressure acted on Explosion-proof cap bottom surface produce an active force upwards to Explosion-proof cap, and Explosion-proof cap rotates around the axis under force, is opened in venting of dust explosion hole, and the pressure in stove is released.After Explosion-proof cap is opened and forwarded certain angle to, bump against the limited block on guide rod 4, stop operating, under self gravitation and the effect of spring 5 elastic force, automatic fall-back, closes again by venting of dust explosion hole.
The utility model structure is simple, and processing and manufacturing is easy, safe and reliable, economic and practical.Multiple mineral hot furnace equipment use for many years, through checking very economical being suitable for, safe and reliable.
Claims (1)
1. mineral hot furnace can automatic fall-back Explosion-proof cap, and its technical characteristic is: be made up of Explosion-proof cap, hinged-support, bearing pin, guide rod and spring etc., Explosion-proof cap bearing pin is fixed on hinged-support, rotate around hinge, guide rod is with limited block and spring, when furnace pressure superpressure, Explosion-proof cap rotates, open venting of dust explosion hole, realize pressure release, after pressure release completes, Explosion-proof cap is under self gravitation and spring force effect, can reset by automatic fall-back, venting of dust explosion hole is closed again.
