Abstract

The utility model relates to a heat-insulating protective device for preventing the backfire and the burning of the adhesive tape of a coal feeder. The device comprises a tubular inner shell, wherein a coal feeder flange arranged at the upper end of the inner shell; plate-like valves respectively hinged on both sides of the lower end of the inner shell, wherein a horizontal-type flat plate door is arranged on one side of the hinged joint and a counter weight heavier than the flat plate door is arranged on the other side of the hinged joint; an outer shell enclosing the lower part of the inner shell, wherein the upper end part of the outer shell is hermetically connected with the outer surface of the inner shell and the lower end part thereof is opened and mounted with a boiler flange. The heat-insulating protective device solves the problems of the back fire and the burning of the adhesive tape in the boiler, can not only ensure the smooth non-resistance coal feed but also prevent the back fire and the leakage of hot pressure gases, allows the parts inside the coal feeder to run at the room temperature, and enables the parts of the coal feeder to run normally with long service life.

Description

The anti-adhesive tape heat insulating protecting apparatus that burns of feeder anti-backfire
Technical field
The utility model relates to the material conveying device of feeder, especially the anti-adhesive tape heat insulating protecting apparatus that burns of feeder anti-backfire.
Background technology
At present; the feeder that steel mill of power plant uses; because boiler combustion is indoor is to supply coal charge in the situation that pressure is arranged; high-pressure hot gas enters feeder when failing to be convened for lack of a quorum constantly along with the defeated material of coal supply; make and heat up rapidly in the feeder casing; under this working environment; not not how long; carry adhesive tape; protective device and electric equipment wherein; that just can damage is quite serious, even all scraps, even resistant to elevated temperatures conveying adhesive tape also can't bear the long-term use under this high thermal environment; the accident that can often burn conveyer belt, this is an insoluble always problem.
Summary of the invention
In order to solve the problem that present feeder exists; the utility model provides a kind of feeder anti-backfire the anti-adhesive tape heat insulating protecting apparatus that burns; this device can thoroughly solve the tempering of boiler and the drawback of burning adhesive tape; can make the smooth logical without hindrance coal supply of coal; can prevent tempering again, prevent the hot pressing flow leakage; equipment in the coal supply cabinet is all moved under the normal temperature state, can guarantee equipment normally operation under the long-life state of feeder.
The technical scheme that its technical problem that solves the utility model adopts is: this device comprises: feeder flange, shell body, valve, inner housing and boiler flange five parts; It is characterized in that: this device has the inner housing of a upper and lower opening tubulose, and the upper end of inner housing is fitted with the feeder flange with the feeder coupling; The both sides, lower end of inner housing are hinged respectively the tabular valve that can shelter under shed are installed, and are boundary with the hinged place of this valve and inner housing, and the one side is the plain batton door of horizontal, and opposite side is equipped with the balance weight body greater than plain batton door weight; Bottom at inner housing is surrounded by shell body, and the shell body upper end is connected with the sealing of inner housing outer surface, underpart opening, and the boiler flange that is connected with the boiler coupling is installed, can satisfy valve opening and closing movement easily in its shell body.During use, the feeder flange is installed with giving door machine coupling, boiler flange and boiler coupling are installed, under the not coal supply state, because the pressure of counter weight makes valve block the under shed of inner housing all the time, red-hot air-flow in the boiler can't be entered in the feeder, can not burn out the structures such as conveyer belt in the feeder; When carrying coal charge,, make red-hot air-flow still can't enter feeder because the impact of coal charge impels the valve corresponding opening to boiler.
Its beneficial effect is: the anti-adhesive tape heat insulating protecting apparatus that burns of feeder anti-backfire; this device can thoroughly solve the tempering of boiler and the drawback of burning adhesive tape; can make the smooth logical without hindrance coal supply of coal; can prevent tempering again, prevent the hot pressing flow leakage; equipment in the coal supply cabinet is all moved under the normal temperature state, can guarantee equipment normally operation under the long-life state of feeder.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and the embodiments;
Accompanying drawing is a structural principle schematic diagram of the present utility model;
Among the figure, 1 feeder flange, 2 shell bodies, 3 valve, 4 balance weight body, 5 inner housings, valve after 6 displacements, 7 valve, 8 boiler flanges.
The specific embodiment
In the drawings, this device comprises: feeder flange 1, shell body 2, valve 3,7, inner housing 5 and boiler flange 8 five parts; It is characterized in that: this device has the inner housing 5 of a upper and lower opening tubulose, and the upper end of inner housing 5 is fitted with the feeder flange 1 with the feeder coupling; The both sides, lower end of inner housing 5 are hinged respectively the tabular valve 3,7 that can shelter under shed are installed, and are boundary with the hinged place of this valve 3,7 and inner housing 5, and the one side is the plain batton door of horizontal, and opposite side is equipped with the balance weight body 4 greater than plain batton door weight; In the bottom of inner housing 5, surrounded by shell body 2, shell body 2 upper ends are connected with the sealing of inner housing 5 outer surfaces, underpart opening, and the boiler flange 8 that is connected with the boiler coupling is installed, can satisfy valve 3,7 opening and closing movement easily in its shell body 2.During use, feeder flange 1 is installed with giving door machine coupling, boiler flange 8 is installed with the boiler coupling, under the not coal supply state, because the pressure of counter weight 4 makes valve 3,7 block the under shed of inner housing 5 all the time, red-hot air-flow in the boiler can't be entered in the feeder, can not burn out the structures such as conveyer belt in the feeder; When carrying coal charge,, make red-hot air-flow still can't enter feeder because the impact of coal charge impels the valve corresponding opening to boiler.
In the drawings, the shape of shell body 2 can the side's of making frustum formula, and promptly top is big, and the lower end is little, also can make the square bodily form or cone shape, and key is must make the valve folding freely, can not influence the conveying coal charge.
In the drawings, this device use material, should select steel plate or iron plate for use, should be high temperature resistant and possess high-intensity sheet material, its thickness is determined as requested.
