Description
Technical field
The utility model relates to a kind of boiler component, particularly a kind of hydrostat, specifically a kind of oil-burning gas-fired boiler explosion proof door.
Background technology
For a long time. heating boiler fuel relies on coal mostly, but generally all there is two large problems in coal-burning boiler: unprecedented environmental pollution and huge cost of transportation.Therefore, government also actively seeks and promotes clean energy resource, carries out cleaner production, reduces the use amount of material and the energy in products & services, realizes the minimum quantization of pollutant emission, reduces the discharge of noxious material.Under such overall situation, oil-burning gas-fired boiler arises at the historic moment, the oil-burning gas-fired boiler quick heating, the discharge capacity of noxious material is little, simultaneously because of its environmental protection, health, energy-conservation, efficiently dominate the market rapidly.But oil-burning gas-fired boiler is in running, and pressure in the burner hearth moment is excessive, approaches explosion limit, if can not discharge in time, be easy to produce blast.
Summary of the invention
The purpose of this utility model is in order to solve oil-burning gas-fired boiler in use, because of abnormal operation, cause burner hearth operating pressure of interior moment excessive, while surpassing certain limit, pressure can not be discharged moment, easily blast and cause the problem of the bursting of boilers and casualties, and a kind of oil-burning gas-fired boiler explosion proof door is provided.
The utility model is achieved through the following technical solutions:
A kind of oil-burning gas-fired boiler explosion proof door, comprise explosion-proof base plate and explosion-proof door closure, and the center of explosion-proof base plate offers relief port, is evenly equipped with at least two fixing screw rods vertical with explosion-proof base plate on explosion-proof base plate; The periphery of explosion-proof door closure has inwardly vertically extended a circle flange, be evenly equipped with at least two fixing sleeve pipes vertical with explosion-proof door closure on the inner surface of explosion-proof door closure, the position that explosion proof door covers the corresponding sleeve pipe mouth of pipe offers communicate with sleeve pipe uncovered, and the inner surface of explosion-proof door closure and flange is provided with heat-insulation layer, insulation layer surface is provided with flame retardant coating; The sleeve pipe that explosion proof door covers is identical with screw rod quantity on explosion-proof base plate and position is corresponding one by one, screw rod on explosion-proof base plate is inserted in the sleeve pipe that explosion proof door covers and screw head is twisted and is provided with nut, position near explosion-proof base plate in the sleeve pipe of explosion-proof door closure is fixed with fixture block, be arranged with Compress Spring on the screw rod of explosion-proof base plate, on the fixture block of one end overhead in sleeve pipe of Compress Spring, other end overhead (tension force that Compress Spring produces can compress explosion-proof door closure and explosion-proof base plate, and the screw rod while is also played the effect of guide rail) on the nut of screw head.
The utility model can be divided into two integral parts substantially: the as a whole part of explosion-proof base plate and screw rod, explosion-proof door closure, flange, sleeve pipe, heat-insulation layer, the as a whole part of flame retardant coating, above-mentioned two integral parts link together by screw rod and Compress Spring elasticity.During use, the explosion-proof base plate of the utility model device is fixed on the boiler furnace mouth, and when pressure in the burner hearth increases, pressure pushes away explosion-proof door closure and accessory structure outwards moves along the screw rod direction, now explosion-proof base plate separates with explosion-proof door closure, discharges impact energy superfluous in burner hearth; After impact energy discharges, pressure in the burner hearth reduces, and Compress Spring is under the effect of himself tension force, spring momentary recovery original state, promote explosion-proof door closure and accessory structure thereof and move inward and compress explosion-proof base plate along the screw rod direction, make explosion-proof door closure and explosion-proof base plate closure, restPose.By said process, just effectively protected boiler itself and operating personnel's safety.
Further, an intrinsic observation tube is inserted in the center of explosion-proof door closure, and the inner port of observation tube communicates with the relief port of explosion-proof base plate, pyroceram is installed on external port.Setting party's convenient operation personnel of observation tube understand the combustion case in boiler furnace.
Position near external port in observation tube is provided with turnover panel.When the inapplicable observation tube of operating personnel, the turnover panel that just can overturn blocks pyroceram, and the radiant heat of prevention burner hearth toasts pyroceram for a long time, has extended the service life of pyroceram.
Heat-insulation layer is the alumina silicate heat-insulation layer, and flame retardant coating is formed by the refractory concrete cast, fixing by hook between heat-insulation layer and flame retardant coating.Alumina silicate heat-insulation layer and refractory concrete wide material sources, thermal insulation fire-resistant are effective, with low cost, and set up the steadiness that hook strengthens the two further between two-layer, have improved service life of the present utility model.
The utility model is reasonable in design, simple in structure, and freely, the release effect is splendid in activity, has improved the safety coefficient of oil-burning gas-fired boiler, has ensured operating personnel's personal safety, is a kind of new type explosion proof device be worthy to be popularized.
