Abstract
The utility model relates to a coal gate plate for a coaling bucket. The coal gate plate comprises a coal gate plate body; a circle of cooling channel is formed on the outer circle of the coal gate plate body; cooling liquid is filled in the cooling channel; a liquid replacement opening is formed on the cooling channel; and a plug is arranged in the liquid replacement opening and is a wooden plug. The coal gate plate for the coaling bucket has the benefit that during practical use, after hot flue gas radiated by a hearth is in contact with the coal gate plate body, the heat of the hot flue gas radiated by the hearth can be completely adsorbed by the cooling liquid in the cooling channel, so that the temperature of the radiated hot flue gas can not reach an ignition point of fire coal in the coaling bucket, and the fire coal is not easy to ignite. Therefore, the coal gate plate body and the coaling bucket are protected, the service life of the coaling bucket is prolonged, and potential safety hazards are eliminated.
Description
Technical field
The utility model relates to a kind of coal bunker that adds, and relates 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.
The utility model content
The utility model purpose is that 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 is provided for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of coal flashboard that adds coal bunker, comprise 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 utility model compared with prior art has advantage:
The coal flashboard that adds coal bunker of the utility model 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 the utility model technical scheme 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 of the coal flashboard that adds coal bunker of the utility model;
Accompanying drawing 4 is the user mode sketch map of the coal flashboard that adds coal bunker of the utility model;
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 and specific embodiment the utility model is done further to specify.
The described a kind of coal flashboard that adds coal bunker of the utility model 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.
The described a kind of coal flashboard that adds coal bunker of the utility model 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.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
