Description

A kind of air draft energy-saving stove

Technical field

The utility model relates to Domestic combustor stove and accessory, especially relates to a kind of air draft energy-saving stove.

Background technology

In order to save the energy, reduce and pollute, people constantly improve stove and accessory in recent years, burn lump coal changed burning moulded coal into by the past, can utilize coal dust to do fuel, and cost is low.But now widely used various coal briquette stove, its structure is not too reasonable, cause flue gas that temperature is very high directly, rapidly discharged to airspace, heat can not make full use of, and wastes energy large; In addition the stove in burner hearth is fixed at last, just cannot change fuel height by adjusting fire grate, to meet the different needs to heat, again can not be to supplemental oxygen in burner hearth, help burning, because temperature in burner hearth is difficult to improve, thus existing coal briquette stove, just can not be used as heating simultaneously and cook, cooking, can not meet needs, and existing stove and accessory air discharge structure arranges unreasonablely, tend to pollute, when serious, can also cause indoor gas poisoning.

Utility model content

So the purpose of this utility model in order to overcome the shortcoming of existing combustion furnace, kitchen range, provides, the thermal efficiency is high, the speed of getting angry is fast, air draft is effective, eliminate room air pollution, alleviates a kind of air draft energy-saving stove of outdoor environment atmosphere pollution.

The utility model solution solves existing technical problem by the following technical solutions.

An energy-saving stove, its structure comprises: stone or metal plate for standing a stove on as a precaution against fire, furnace shell, burner hearth, sandy soil layer, ventilating opening, fire grate, ashes drawer, stockhole, a legs and feet, cigarette hole.The left side of described furnace shell arranges ventilating opening, the upside of ventilating opening is communicated with cigarette hole, cigarette hole is connected with chimney, described stone or metal plate for standing a stove on as a precaution against fire is fixedly mounted on the top of furnace shell, and ashes drawer is arranged on the lower end of furnace shell, and described burner hearth is arranged on the middle position of furnace shell inside, fire grate is arranged on the below of burner hearth, described stockhole, at the middle position of stone or metal plate for standing a stove on as a precaution against fire, is filled sandy soil layer between burner hearth and furnace shell, and the lower end in described furnace shell outside arranges a legs and feet.

Further, described legs and feet have four, and four legs and feet are separately positioned on the position at four angles of lower end outside furnace shell, and four each and every one prop up legs and feet is supporting whole stove and accessory.

Further, described fire grate is to be formed by pig iron casting, and fire grate can rock, and is ashes drawers under fire grate, and comburant produces ashes after stove internal combustion, by rocking fire grate, ashes is drained to ashes drawer so that ash discharge.

Further, on the hearth wall in described furnace shell, adhere to refractory masses, refractory masses is bonded on furnace shell by sandy soil layer is attached.

Further, the design in described ventilating opening and cigarette hole, the air-flow while making to burn flows along flow of flue gas direction, by ventilating opening, flow to stove and accessory cigarette hole, then is connected with chimney, is discharged to outside.The Proper Match of its flue and burner hearth and chimney volume, thus the drawbacks such as coal gas dust is large avoided in traditional stove and accessory, and because it is rational in infrastructure easy, can use and multiple coal-fired fuel.

The beneficial effects of the utility model are: one, combustion heat value is high, and the structure of stove and accessory makes burning more abundant, even coal stone, cinder also can be as fuel; Two, energy-conservation, its Flue duct design is more reasonable, make heat energy be difficult for scattering and disappearing, thereby energy-conservation feature of economizing on coal is very obvious, more old-fashioned stove and accessory, the energy-conservation 60%-70% that reaches; Three, safety, its structural design and air is sucked in stove, can not cause carbon monoxide disperse in air, has avoided gas poisoning; Four, health, fills out while subtracting coal and can not smolder, thereby has guaranteed indoor cleaning, and this is also that traditional stove and accessory is beyond one's reach.
