Owing to there is thorn fire during mine heat furnace smelting, collapse material, exhaust gas volumn is very big instantaneously, flue-gas temperature is high, first itself there is 10-15mm space between fire door and body of heater, although the traditional lifting furnace door of semiclosed mineral hot furnace will have high heat resistance and intensity, but it is very large on fire door impact, after using a period of time, there is fire door distortion, localized voids reaches 20mm-50mm, and high-temperature flue gas is from door upper part and both sides benefit, there is uncontrollable discharge, produce smoke pollution.Secondly the lifting device (elevator or lifting hydraulic cylinder, steel wire rope, steel link chain) of fire door only has one-level insulating properties, and when naked or damage, body of heater charged or greatly ground connection electricity to the steel wire rope of lifting device, form grounded circuit, a large amount of electric energy is had in this conductive path, the steel wire rope of sparking electric discharge meeting scaling loss traction fire door, affects the safe operation of equipment.
The hot furnace door of current avasite is monolithic castable perfusion property, weight is large, and effect of heat insulation is bad, fire door is transform as the light weight type fire door of thermal insulating steel structural framing, namely improve effect of heat insulation, reduce fire door weight again, Castable on Gate lightweight plasticity casting refractory is tied a knot, increase effect of heat insulation, also reduce fire door weight simultaneously.
Summary of the invention
The purpose of this utility model will provide a kind of for the excessive technology Problems existing of existing preventing dust exactly, increase prevent that flue gas is excessive together, sealing, good insulation preformance and the heat insulation fire door of the simple semiclosed mineral hot furnace gear cigarette of structure.
The utility model is achieved through the following technical solutions:
A kind of mineral hot furnace insulation stop cigarette fire door, comprise interior fire door 1 and outer fire door 3, described outer fire door 3 both sides are provided with column 9, and this outer fire door 3 is arranged between described column 9, is provided with insulating part 2 between outer fire door 3 and column 9; Seal 7 is provided with between described interior fire door 1 and outer fire door 3; Described interior fire door 1 is steel structure frame, fills plasticity casting refractory in interior fire door 1; Be provided with recirculating cooling water system 6 in described interior fire door 1, this recirculating cooling water system 6 is made up of the three-back-shaped cooling tube be built in interior fire door 1, the water inlet pipe being connected to three-back-shaped cooling tube two ends place and outlet pipe.
This described mineral hot furnace insulation stop cigarette fire door also comprises furnace door lifting device, this furnace door lifting device by being arranged on the insulating fixing piece 8 on outer fire door 3 top, hoist cylinder 5 forms with the steel wire rope 4 being used for being connected insulating fixing piece 8 and hoist cylinder 5, this furnace door lifting device and described outer fire door 3 are structure as a whole.
Compared with prior art, the beneficial effects of the utility model are:
1) interior fire door 1 is the steel structure frame that quality is light, plasticity casting refractory is filled in interior fire door 1, this plasticity casting refractory is made up of with addition of fibrous mineral cotton high aluminium material, refractory temperature can reach 900 DEG C, interior fire door 1 is made to have extremely strong heat-blocking action, for promoting effect of heat insulation and increasing the service life, lay in interior fire door 1 and arrange Back Word type cooling water pipe, the heat-blocking action of interior fire door 1 is further enhanced.
2) in employing, between fire door 1 and column 9, insulating part 2 is set, the method to set up of the insulating fixing piece 8 on seal 7 and outer fire door 3 top is provided with between interior fire door 1 and outer fire door 3, avoid body of heater charged or greatly ground connection electricity to the steel wire rope 4 of lifting device, form grounded circuit, a large amount of electric energy is had in this conductive path formed, the steel wire rope 4 of electric discharge phenomena meeting scaling loss traction fire door, affects the safe operation of equipment.
3) there is gap in the single lifting furnace door top and the sidepiece that eliminate tradition preparation, there is the phenomenon that the fiery flue gas of string is excessive, greatly reduce uncontrollable discharge, promote dust removing effects.
4) fire door is transform as the light weight type fire door of thermal insulating steel structural framing, namely effect of heat insulation is improved, reduce fire door weight again, Castable on Gate lightweight plasticity casting refractory is tied a knot, increase effect of heat insulation, also reduce fire door weight, the lightweight fire door life-span is 2-3 times than the traditional type fire door life-span simultaneously, and integrated cost is low, easy to maintenance.
