The utility model relates to a kind of anti-explosive door for boiler device, comprise the base plate being arranged on boiler furnace mouth periphery, the cover plate overlaying on stockhole top, be located at limiting plate above stockhole, and be provided with screw rod in turn through limiting plate, cover plate and base plate, and the two ends of screw rod are respectively by fastening nuts; Screw jacket between described limiting plate and cover plate fills holddown spring.Explosion vent apparatus described in the utility model, can set explosion proof door release pressure, protection burner hearth not superpressure.Can playback smoothly after take-off, not need artificial adjustment.Ensure that explosion proof door can continue to use, ensure burner hearth and extraneous good seal.Anti-explosive door for boiler device described in the utility model effectively can ensure burner hearth not superpressure, ensures excellent sealing, does not leak; Safe and reliable; Make simple, cost is low.
Description
Technical field
The utility model relates to a kind of boiler protection device for detonation pressure in boiler furnace of releasing.
Background technology
During boiler operatiopn, boiler furnace is often because the insufficient or burner hearth of burning has unburned fuel, detonation can be formed at burner hearth during ignition of the boiler, detonation pressure may exceed body of heater and bear pressure, so need to arrange explosion-protection equipment on boiler furnace, can when detonation relieving pressure, ensure that pressure in the burner hearth is no more than authorized pressure, ensure burner hearth safety.
General burner hearth explosion-protection equipment is all utilize gravity type explosion proof door.This apparatus structure is simple, seals bad, easily leaks fire and jeopardizes safety.Particularly the burner hearth of pressure combustion more easily leaks cigarette.Cost of manufacture is also high.
Summary of the invention
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of anti-explosive door for boiler device, effectively ensure that burner hearth, isolated burner hearth high-temperature flue gas and the external world, avoids explosion proof door and seals hidden danger that is bad, flue gas leakage when pressure combustion.
The technical solution of the utility model is, a kind of anti-explosive door for boiler device, comprise the base plate being arranged on boiler furnace mouth periphery, the cover plate overlaying on stockhole top, be located at limiting plate above stockhole, and be provided with screw rod in turn through limiting plate, cover plate and base plate, and the two ends of screw rod are respectively by fastening nuts; Screw jacket between described limiting plate and cover plate fills holddown spring.
At the outer mounting limit plate of stockhole, be unlikely to cover plate and fly out, ensure safety.When detonation occurs in burner hearth igniting, when furnace pressure exceedes the release pressure of setting spring explosion proof door, cover plate take-off, furnace pressure of releasing, waits furnace pressure to reduce, and under the pressure of the spring, cover plate playbacks along screw rod, ensure that good seal.Cover plate spring compression, thrust can adjust as requested, the vent pressure of setting explosion proof door.
Be provided with sealing mechanism between described cover plate and base plate, described sealing mechanism comprises seal groove, the encapsulant be filled in seal groove on the base plate plate face that is located at and contacts with cover plate.
Described encapsulant is asbestos cord.
Be arranged with the outside that 4 screw rods are distributed in burner hearth, as guider during cover plate pressure release.
Explosion vent apparatus described in the utility model, can set explosion proof door release pressure, protection burner hearth not superpressure.Can playback smoothly after take-off, not need artificial adjustment.Ensure that explosion proof door can continue to use, ensure burner hearth and extraneous good seal.Boiler spring explosion vent apparatus described in the utility model effectively can ensure burner hearth not superpressure, ensures excellent sealing, does not leak; Safe and reliable; Make simple, cost is low.
Accompanying drawing explanation
Fig. 1 is the longitudinal cross-section schematic diagram of anti-explosive door for boiler device described in the utility model.
Detailed description of the invention
As shown in Figure 1, a kind of anti-explosive door for boiler device, comprise the base plate 8 being arranged on boiler furnace mouth periphery, the cover plate 7 overlaying on stockhole top, be located at limiting plate 5 above stockhole, and be provided with screw rod 3 in turn through limiting plate 5, cover plate 7 and base plate 8, and the two ends of screw rod 3 are fastening respectively by nut 4, be arranged with the outside that 4 screw rods 3 are distributed in burner hearth 10; Screw rod 4 between limiting plate 5 and cover plate 7 is outer is set with holddown spring 9.Burner hearth periphery is provided with smoke guiding tube 1, and smoke guiding tube 1 is connected with hearth outer wall by ring flat-plate 2.
Be provided with sealing mechanism between cover plate 7 and base plate 8, sealing mechanism comprises seal groove, the encapsulant 6 be filled in seal groove of the bilayer on the base plate 8 plate face that is located at and contacts with cover plate 7, and encapsulant 6 is asbestos cord.
