Abstract

The utility model discloses a furnace door for biomass fuel boiler, comprising a door frame, a left door closure and a right door closure separately installed on the left and right side of the door frame through connection hinges; the left edge of the right door closure is pressed on the right edge of the left door closure when the door closures are closes; a locking mechanism is installed between the door frame and the upper and lower part of the left edge of the right door closure for locking the right door closure on the door frame; aluminum silicate fiberboards are installed inside the left door closure and the right door closure; the aluminum silicate fiberboards are equipped with fire-resistant concrete layers; braided asbestos square packing installed in the door frame rope groove is arranged on the overlapping part between the door frame and the left and right door closures. Comparing with the existing universal miniature furnace door, the utility model effectively solves the problems of manual feeding difficulty, easy furnace door blockage and cleaning difficulty in case of biomass fuel with large bulk; casting structural members and sealing heat-insulating materials used in the utility model provide advantages of heat resistance, deformation resistance, good sealing performance, uneasy fall-off of furnace wall heat-preserving materials, simple and reasonable structure and so on.

Description

A kind of fire door of biomass fuel boiler
Technical field
The utility model relates to boiler, specifically is meant the fire door that is used for biomass fuel boiler.
Background technology
It is the Boiler door of fuel that the less fire door of existing boiler is not suitable for as living beings, the problem of easy to clean not after this less fire door stops up easily and stops up because of the biomass fuel volume greatly produces the difficulty that manually feeds intake, fire door, and its to seal heat-proof quality also bad.
The utility model content
The technical problems to be solved in the utility model is, at the defective that prior art exists, designs a kind of fire door of biomass fuel boiler, and the biomass fuel that is suitable for larger volume feeds intake and keeps fire door not stop up, and the oven door sealing thermal insulation is good, and is heat-resisting not yielding.
Technical solutions of the utility model are that the fire door of described biomass fuel boiler comprises doorframe and covers and right door closure with being connected the corresponding left-hand door that is installed in this doorframe left and right sides of hinge respectively; Left-hand door lid is with right door closure when closed, the edge, the right of the left margin clinching left-hand door lid of right door closure, and its design feature is, the top in described right door closure left side and bottom can be with the locking mechanisms that should right side door closure be locked on the doorframe with being equipped with respectively between the doorframe; Described left-hand door lid all is equipped with aluminosilicate fiberboard with the inboard of right door closure, and on this aluminosilicate fiberboard the refractory concrete layer is installed; Described left-hand door lid and right door closure are provided with the braided asbestos square packing that is contained in the doorframe grooving with the coincidence position of doorframe.
Below the utility model made further specify.
Referring to Fig. 1, the fire door of biomass fuel boiler described in the utility model comprises doorframe 1 and cuts with scissors the 3 corresponding left-hand doors lids 5 and right door closures 2 that are installed in this doorframe 1 left and right sides with being connected respectively; The right of the left margin 4 clinching left-hand doors lid 5 of right door closure 2 is along 17 (referring to Fig. 2) when left-hand door lid 5 and right door closure 2 closures, its design feature is, the top in described right door closure 2 left sides and bottom can be with the locking mechanisms 10 that should right side door closure 2 be locked on the doorframe 1 with being equipped with respectively between the doorframe 1; Described left-hand door lid 5 all is equipped with aluminosilicate fiberboard 7 with the inboard of right door closure 2, and on this aluminosilicate fiberboard 7 refractory concrete layer 6 is installed; Described left-hand door lid 5 and right door closure 2 are provided with the braided asbestos square packing 16 that is contained in the doorframe grooving with the coincidence position of doorframe 1.
Referring to Fig. 3, a kind of structure of described locking mechanism 10 is, card post 12 usefulness the securing members 11 of band draw-in groove are fixedly mounted on the doorframe 1, and the rear end is that the locking bar 14 of handle is installed on the right door closure 2 and serve as spool to rotate a described handle locking bar 14 front ends are entered in the described draw-in groove of card post 12 with bearing pin screw 13 through bearing pin screw 13.
During actual installation, the utility model fire door is connected and fixed with boiler by each bolt 15 on the doorframe 1; When opening fire door, the handle of rotation locking bar 14 and locking bar 14 front ends are separated with card post 12 can draw back by this handle then that stove face plate feeds intake or cleaning work; Rotate described handle and can make locking bar 14 front ends and the interlock mutually of card post 12 again, promptly closed fire door.Refractory concrete layer 6, aluminosilicate fiberboard 7 play function of heat insulation, reduce metal heated distortion; Braided asbestos square packing 16 is stuck in the gap of door closure and doorframe can play sealing function preferably.
As known from the above, the utility model is a kind of fire door of biomass fuel boiler, it is than existing general small-size fire door, efficiently solve the biomass fuel volume manually feed intake when big difficulty, fire door stop up easily and stop up after the problem of easy to clean not, and cast structure spare and sealed heat insulating material have been used, make stove and accessory that advantages such as heat-resisting not yielding, good seal performance, insulation of wall material difficult drop-off be arranged, structure is advantages of simple more also.
