Description
Technical field
This utility model relates to boiler design field, the compound door structure of a kind of waste heat boiler.
Background technology
The fire door of conventional boiler mostly is the arch fire door of plain cast iron, and its limit heat resisting temperature is at about 450 DEG C；And one
The import flue gas limiting temperature of a little waste heat boilers often reaches more than 500 DEG C, thus the arch fire door of plain cast iron easily because of
Cause gross distortion for high temperature, thus the sealing property of boiler cannot be ensured, cause all kinds of potential safety hazard.
Utility model content
For the problems referred to above, the compound door structure of a kind of waste heat boiler of this utility model, it can solve plain cast iron
Arch fire door does not reaches, because of limiting temperature, the problem required and be deformed, cannot ensure boiler seal.
Its technical scheme is, the compound door structure of a kind of waste heat boiler, it is characterised in that: it include furnace door frame and
Fire door panel, the blend stop being formed around engaging continuously of the rear end of described furnace door frame, depend on from back to front in described furnace door frame
Secondary closely knit be filled with High-strength refractory concrete brick layer, flame retardant coating and heat-insulation layer and by described fire door panel from described fire door
The front seal of framework, the rear end face of described High-strength refractory concrete brick layer is spacing by described blend stop.
Further, the trailing flank of described fire door panel is provided with two groups of parallel annular flat steel bars, described two groups of annulars
Being embedded with seal trim strip between flat steel bar, when described fire door panel closes with described furnace door frame, described seal trim strip compresses described stove
The leading flank surrounding of door frame.
Further, described High-strength refractory concrete brick layer is by some pieces of High-strength refractory concrete brick overlap joint split structures
Becoming, the leading flank of each block of described extremely fireproof concrete brick all has re-entrant cavity, and described flame retardant coating is the silicon of high pressure solidity
Acid aluminum fiber, alumina silicate fibre is closely knit to be filled in described furnace door frame internal procedure to deform and is i.e. packed into described re-entrant cavity
In thus be engaged with described High-strength refractory concrete brick layer.
Further, the bottom surface of described furnace door frame is symmetrically arranged at the front end with leg, is provided with bottom described fire door panel
Connector, described connector is rotatably connected by rotating shaft with described leg, between described furnace door frame and described fire door panel
Locked by the clamping screw of upper end.
Further, described leg offering along front rearwardly extending waist hole, described rotating shaft is installed on described waist
In hole and can move forward and backward along described waist hole.
Further, the leading flank of described fire door panel is provided with handle.
The beneficial effects of the utility model are: it passes through the most closely knit strong concrete being filled in furnace door frame
Brick layer, flame retardant coating and heat-insulation layer are effectively improved fire resistance and the heat insulating ability of whole door structure, effectively prevent fire door because of fire-resistant,
Poor thermal insulation property and the deformation that causes, it is ensured that the sealing of fire door；And owing to strong concrete brick layer only relies on firedoor frame
On rear side of frame, the blend stop of surrounding carries out spacing so that in the rear most of strong concrete brick layer and burner hearth smoke contacts from
And playing sufficient resistance to fire action, it is to avoid the furnace door frame of steel construction is because of high temperature deformation in burner hearth；It is arranged at inside fire door panel
On face, the seal trim strip between two groups of parallel annular flat steel bars can be further ensured that when fire door panel closes and firedoor frame
Sealing property good between frame.

Detailed description of the invention
Seeing Fig. 1～Fig. 4, the compound door structure of a kind of waste heat boiler of this utility model, it includes furnace door frame 1 and stove
Door face board 2, the blend stop 3 being formed around engaging continuously of the rear end of furnace door frame 1, the most closely knit in furnace door frame 1
It is filled with High-strength refractory concrete brick layer 4, flame retardant coating 5 and heat-insulation layer 6 and by fire door panel 2 before furnace door frame 1
Side seal, the rear end face of High-strength refractory concrete brick layer 4 is spacing by blend stop 3；The trailing flank of fire door panel 2 is provided with two groups and puts down
The annular flat steel bar 7,8 of row, is embedded with seal trim strip 9 between two groups of annular flat steel bars 7,8, and fire door panel 2 closes with furnace door frame 1
Time seal trim strip 9 compress the leading flank surrounding of furnace door frame 1.
High-strength refractory concrete brick layer 4 is made up of some pieces of High-strength refractory concrete brick overlap joint splits, and each piece high
The leading flank of degree refractory concrete cob brick all has re-entrant cavity 10, and flame retardant coating 5 is the alumina silicate fibre of high pressure solidity, aluminium silicate fiber
Tie up closely knit be filled in furnace door frame 1 internal procedure generation become be packed into re-entrant cavity 10 immediately in thus with high-strength fireproof coagulation
