Abstract
The utility model relates to a boiler and particularly relates to an explosion-proof boiler. The explosion-proof boiler comprises a furnace door doorframe and a door cover with a support rod, wherein a door cover base is installed on the outer surface of the doorframe, the door cover base is provided with a groove and the support rod of the door cover is clamped in the groove, the periphery of the door cover base is symmetrically provided with screw bolts, outer ends of the screw bolts are provided with limit pieces which can limit the door cover to move outwards, the limit pieces are fastened on the screw bolts through nuts, and compression springs are sleeved on the screw bolts and are arranged on the inner sides of the limit spaces. The utility model provides the explosion-proof boiler of which the furnace door has overhaul, fire watching, ventilation and explosion proofing functions. When the boiler runs normally, the furnace door of the boiler can ventilate and regulate the internal pressure of the boiler. When deflagration or combustion deterioration occurs, the door cover can be opened by the action of the explosion-proof device and the pressure in a hearth can be released, so that the furnace walls of the boiler or the pressure parts of the boiler can be protected.
Description
Technical field
The utility model relates to boiler.
Background technology
General Boiler door is the inlet that overhauls fast, is the passage that burner hearth poked fire or beat Jiao and deashing.In service at the negative-pressure firing boiler, fire door do not provide wind or secondary wind to burner hearth.When detonation took place, fire door did not have explosion prevention function yet.
The utility model content
The technical problem that the utility model will solve is, to the deficiency that prior art exists, designs a kind of explosion-proof boiler, when normal operation of boiler, to burner hearth wind or secondary wind is provided; When boiler furnace generation detonation, the fire door door closure is opened under the immense pressure that detonation produces, and discharges furnace pressure, avoids detonation to damage furnace wall or boiler pressure parts.
The technical scheme of the utility model is that a kind of explosion-proof boiler comprises fire door doorframe and the door closure of being with support bar; It is characterized in that said doorframe outer surface is equipped with the door closure base, said door closure base is provided with groove and the door closure support bar is installed in this groove; Door closure base periphery symmetry is equipped with double-screw bolt, and the double-screw bolt outer end is provided with the locating part of the outside moving displacement of restriction door closure, and this locating part is fastened to double-screw bolt through nut; Suit compression spring on the double-screw bolt, this compression spring places locating part inboard.
Said door closure is provided with anti-flame ventilation shaft, and the ventilation shaft porch is provided with the ventilation that control valve is regulated ventilation shaft.When detonation takes place, cut off ventilation shaft automatically, prevent through flame or the injection high-temperature flue gas outside fire door of ventilating.
Be provided with packing ring between said locating part and the nut.
Said locating part is a trim ring.
When detonation took place, the immense pressure that detonation produces was cut off ventilation shaft, prevents that flame or high-temperature flue gas from spraying outside fire door; Simultaneously, the immense pressure that detonation produces is pushed door closure open, and door closure through compressing spring to external compression, forms the big space of releasing along double-screw bolt between door closure and the door closure base, and high-temperature flue gas discharges outside fire door, reduces furnace pressure, reaches explosion-proof effect.Detonation disappears, and the door closure of fire door automatically resets under the compression spring action.
Known that by above the utility model is explosion-proof boiler, its Boiler door has maintenance, sees fire, ventilation and explosion prevention function.When boiler normally moved, Boiler door can ventilate, and regulated in the stove and pressed.When detonation or burn deterioration take place, the explosion-protection equipment effect, the door closure passive open discharges pressure in the burner hearth, protection boiler setting or boiler pressure parts.
