Abstract
The invention discloses a coal gate of a coal feed hopper, which comprises a coal gate body, wherein a circle of cooling passage is arranged on the outer ring of the coal gate body; cooling liquid is filled in the cooling passage; a liquid exchange opening is arranged on the cooling passage; a stopper is arranged in the liquid exchange opening; and the stopper is a wooden stopper; according to the coal gate of the coal feed hopper, disclosed by the invention, in the actual application process, after hot flue gas radiated from a hearth touches the coal gate body, the cooling liquid in the cooling passage can completely absorb the heat of the hot flue gas radiated from the hearth, so as to prevent the temperature of the radiated hot flue gas from reaching the burning point of fire coal in the coal feed hopper, so that the fire coal is not easy to ignite, the coal gate body and the coal feed hopper are protected, the service life of the coal feed hopper is prolonged, and the potential safety hazard is completely eliminated.
Description
Technical field
The present invention relates to a kind of coal bunker that adds, relate in particular to a kind of coal flashboard that adds coal bunker.
Background technology
Boiler is a kind of energy conversion.Hot water that produces in the boiler or steam can also can convert mechanical energy into through Steam Power Equipment, or convert mechanical energy into electric energy through generator more directly for commercial production and people's lives provide required heat energy.Adding coal bunker and be in the boiler is that boiler adds coal-fired parts, and the common coal bunker that adds is shown in accompanying drawing 1; Comprise and add coal bunker 1, handwheel 2 and coal flashboard 3; Handwheel 2 is arranged on and adds on the coal bunker 1, controls the rising and the decline of coal flashboard 3, and the coal-fired entering of control burner hearth what have reached.Because coal flashboard 3 all is to be processed by cast iron, in the use of reality, can not absorb the heat of the hot flue gas that radiation of burner hearth goes out, at this moment, add fire coal 4 in the coal bunker just directly by the hot gas radiation heating of burner hearth, be easy to ignited.So just the someone designs the coal bunker that adds that has water tank, shown in accompanying drawing 2, owing to add the restriction of coal bunker inner space, water tank 5 can only be arranged on the bottom that adds coal bunker.Water tank be unwilling to all cover coal flashboard 3; Therefore still can not absorb the heat of the hot flue gas that radiation of burner hearth goes out fully, coal-fired 4 are still added thermal ignition by hot gas radiation that can burner hearth, make coal flashboard 3 be easy to burn out; The steel plate that adds coal bunker 1 is also burnt easily, has brought great potential safety hazard.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of coal flashboard that adds coal bunker that can absorb the heat of the hot flue gas that radiation of burner hearth goes out fully.
Technical solution of the present invention is achieved in that a kind of coal flashboard that adds coal bunker, comprises coal flashboard body, and the outer ring of said coal flashboard body is provided with a circle cooling duct; In the said cooling duct cooling fluid is housed.
Preferably, have on the said cooling duct and change the liquid mouth; Said changing in the liquid mouth is provided with stopper.
Preferably, said stopper is a stopper.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The coal flashboard that adds coal bunker of the present invention because the outer ring of coal flashboard body is provided with a circle cooling duct, is equipped with cooling fluid in the cooling duct.In the use of reality; After the hot flue gas that radiation of burner hearth goes out was run into coal flashboard body, the cooling fluid in the cooling duct can absorb the heat of the hot flue gas that radiation of burner hearth goes out fully, made the temperature of the hot flue gas that gives off not reach the burning-point that adds the fire coal in the coal bunker; Coal-fired being difficult for ignited; Protect coal flashboard body and added coal bunker, prolonged the service life that adds coal bunker, stopped potential safety hazard.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation that adds coal bunker of prior art;
Accompanying drawing 2 is another structural representation that adds coal bunker of prior art;
Accompanying drawing 3 is the structural representation that adds the coal flashboard of coal bunker of the present invention;
Accompanying drawing 4 is the user mode sketch map that adds the coal flashboard of coal bunker of the present invention;
Wherein: 1, add coal bunker; 2, handwheel; 3, coal flashboard; 4, coal charge; 5, water tank; 6, coal flashboard body; 7, cooling duct; 8, cooling fluid; 9, change the liquid mouth; 10, stopper.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of coal flashboard that adds coal bunker shown in accompanying drawing 3 comprises coal flashboard body 6, and the outer ring of said coal flashboard body 6 is provided with a circle cooling duct 7; In the said cooling duct 7 cooling fluid 8 is housed; Have on the said cooling duct 7 and change liquid mouth 9; Said changing is provided with stopper 10 in the liquid mouth 9; Said stopper 10 is a stopper.
Of the present invention a kind of coal flashboard that adds coal bunker shown in accompanying drawing 4 is in the use of reality, after the hot flue gas that radiation of burner hearth goes out is run into coal flashboard body 6; Cooling fluids 8 in the cooling duct 7 can absorb the heat of the hot flue gas that radiation of burner hearth goes out fully; The temperature of the feasible hot flue gas that gives off does not reach the burning-point that adds the fire coal 4 in the coal bunker 1, and coal-fired 4 are difficult for being ignited, and has protected coal flashboard body 6 and has added coal bunker 1; Prolong the service life that adds coal bunker 1, stopped potential safety hazard.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (3)
