Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Multi-purpose boiler explosion-protection equipment, the explosion proof door of boiler, procuratorial work door and peephole are integrated, only need in the reserved hole of boiler furnace afterbody, just achieve function that is explosion-proof, that check, see fire, there is cost efficiency and safe and practical feature.
For achieving the above object, the technical solution used in the present invention is: a kind of Multi-purpose boiler explosion-protection equipment, and cylindrical shell two ends are welded with mounting flange, adpting flange respectively; Journal stirrup welds with cylindrical shell and adpting flange; Adpting flange and U-shaped cast iron flange are fixed by organizing bolt and nut more; Explosion proof door is connected by journal stirrup stud with cylindrical shell; Fiery device inner side end, is seen concordant with the insulation aspect in cylindrical shell point-blank in the center of circle seeing the center line of fiery device and mounting flange.
There are two symmetrical footstalks described explosion proof door side, and the side of cylindrical shell and adpting flange is provided with two symmetrical journal stirrups.
Be filled with light heat insulation material alumina silicate felt inside described explosion proof door, the skin of alumina silicate felt lays refractory concrete; Refractory concrete mid portion places expanded metal lath, links into an integrated entity with the shell of fastening iron by expanded metal lath and explosion proof door.
It is highly the annular protrusion of 7mm that the housing of described explosion proof door and U-shaped cast iron flange interface have, U-shaped cast iron flange corresponding position be provided with the annular groove matched with projection, the built-in asbestos cord of groove.
The diameter of described groove is 14-18mm.
The diameter of described asbestos cord is 8-12mm.
The housing of described explosion proof door adopts a heat-resisting cast iron cast molding.
Described cylinder shell is rolled by the steel plate that 6mm is thick, identical with the internal material of explosion proof door inside it, alumina silicate felt, refractory concrete, expanded metal lath and fastening iron, and does in aggregates with cylinder shell,
The beneficial effects of the utility model are:
Hydrostat by mounting flange, stud, journal stirrup, explosion proof door, adpting flange, cylindrical shell, U-shaped cast iron flange and see fiery device composition.Mounting flange is connected by the flange that bolt and nut is reserved with boiler body, and middle asbestos cord of placing seals; See fiery device for observing furnace flame; Owing to being provided with explosion proof door, when the large pressure with explosion proof door of furnace pressure, be that turning cylinder opens explosion proof door with stud, after relieving pressure, explosion proof door cuts out under the effect of conducting oneself with dignity; During blowing out maintenance overhaul, open explosion proof door, enter by cylindrical shell that boiler furnace carries out checking, maintenance work.
The utility model is the water-tube boiler explosion-protection equipment of big-and-middle-sized coal dust burning, oil or gas, possesses the purposes of explosion proof door, procuratorial work door and peephole simultaneously.
