Description
Technical field
The present invention relates to the compound door structure in boiler design field, specially waste heat boiler.
Background technology
The fire door of conventional boiler is mostly the arch fire door of plain cast iron, and its limit heat resisting temperature is at 450 DEG C or so；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
Cause gross distortion for high temperature, so as to which the sealing property of boiler can not be ensured, cause all kinds of potential safety hazards.
The content of the invention
In view of the above-mentioned problems, the compound door structure of waste heat boiler of the present invention, it can solve plain cast iron arch fire door
The problem of being deformed because limiting temperature does not reach requirement, boiler seal can not being ensured.
Its technical scheme is the compound door structure of waste heat boiler, it is characterised in that：It includes furnace door frame and fire door
Panel, the rear end of the furnace door frame are surrounded by the blend stop continuously engaged, close successively from back to front in the furnace door frame
High-strength refractory concrete brick layer, flame retardant coating and heat-insulation layer are filled with fact and by the fire door panel from the furnace door frame
Front seal, the rear end face of the High-strength refractory concrete brick layer is spacing by the blend stop.
Further, the trailing flank of the fire door panel is provided with two groups of parallel annular flat steel bars, two groups of annulars
Seal trim strip, fire door panel seal trim strip compression stove when being closed with the furnace door frame are embedded between flat steel bar
The leading flank surrounding of door frame.
Further, the High-strength refractory concrete brick layer overlaps split structure by some pieces of High-strength refractory concrete bricks
Into the leading flank of each block of extremely fireproof concrete brick is provided with re-entrant cavity, and the flame retardant coating is the silicon of high pressure solidity
Sour aluminum fiber, alumina silicate fibre is closely knit to be filled into deform in the furnace door frame internal procedure and is packed into the re-entrant cavity
It is interior so as to being engaged with the High-strength refractory concrete brick layer.
Further, the bottom surface of the furnace door frame is symmetrically arranged at the front end with leg, and the fire door panel bottom is provided with
Connector, the connector are rotatably connected with the leg by rotating shaft, between the furnace door frame and the fire door panel
Locked by the clamping screw of upper end.
Further, the leg on offer along preceding rearwardly extending waist hole, the rotating shaft and be installed on the waist
It can move forward and backward in hole and along the waist hole.
Further, it is provided with handle on the leading flank of the fire door panel.
The beneficial effects of the present invention are：It passes through the closely knit strong concrete brick being filled in furnace door frame successively
Layer, flame retardant coating and heat-insulation layer effectively improve the fire resistance of whole door structure and heat insulating ability, effectively prevent fire door because of fire resisting, protect
Deformation caused by warm poor performance, it is ensured that the sealing of fire door；And because strong concrete brick layer only relies on furnace door frame
The blend stop of rear side surrounding is spacing to carry out so that in the rear most and burner hearth of strong concrete brick layer smoke contacts so as to
Sufficient resistance to fire action is played, avoids the furnace door frame of steel construction because of high temperature deformation in burner hearth；It is arranged at fire door panel medial surface
Seal trim strip between upper two groups parallel annular flat steel bars can be further ensured that when fire door panel closes and furnace door frame
Between good sealing property.
