Description
Technical field
It the utility model is related to a kind of Boiler door, and in particular to a kind of furnace door structure.
Background technology
Fire door is indispensable parts in boiler, and fire door is not only operating personnel and led into what boiler maintenance was checked
Road, the fire door of good seal performance can also improve boiler efficiency.Original door structure sealing is poor, and concrete thickness is relatively thin,
Door closure and doorframe gap are big, and whole door closure uneven heating is even, and heat-insulating property is poor, and no flame-observing hole is inconvenient to see fire.
Utility model content
The utility model is, door closure and doorframe gap thin to solve existing door structure sealing difference and concrete thickness
Greatly, whole door closure uneven heating is even, poor thermal insulation property, and is inconvenient to see the problem of fiery without flame-observing hole, and then provides a kind of new
Type door structure.
The technical scheme that the utility model is taken for solution above-mentioned technical problem：A kind of furnace door structure, it includes door
Lid and doorframe；Door closure side is rotatably installed in doorframe side, and door closure can be opened and locked to doorframe opposite side, and it also includes seeing fire
Hole, heat resistant glass and asbestos board, door closure are tongue-and-groove sealing structure with door frame contact face, and asbestos cord, the door closure are filled with groove
Inboard is provided with heat resistance concrete layer, and door closure center is provided with through hole, and the door closure of the through hole surrounding is provided with mounting groove, mounting groove
In asbestos board be embedded with heat resistant glass, the flame-observing hole, which is inserted into mounting groove, compresses asbestos board, and flame-observing hole is removable with door closure
Unload connection.
The beneficial effects of the utility model are：The utility model door closure uses tongue and groove seal form with door frame contact face,
Central filler asbestos cord or graphite packing, can ensure during use doorframe with outer casing, door closure and doorframe junction, flame-observing hole
No leakage, not dust stratification at doorframe, sealing is strong, and heat-insulating property is strong, can improve the efficiency of boiler, reduces cost, saves resource, increases
If flame-observing hole simultaneously installs heat resistant glass, it is easy to seal and observe state of catching fire in burner hearth.
