Abstract

The utility model belongs to the technical field of heating furnace accessories and discloses a heating furnace gasifying ring. The heating furnace gasifying ring is mainly characterized by comprising an annular ring body with at least one air inlet pipe. The annular ring body comprises a casing and a cavity communicated with the air inlet pipe, and a plurality of air inlet holes are formed in the casing close to the inner side of the annular ring body. During use, the heating furnace gasifying ring is arranged at the position of a furnace mouth, and in an upward flowing process of gas such as carbon dioxide and carbon monoxide, coal dust and the like generated in burning in a hearth, the negative pressure is formed at the position of the furnace mouth. Under the effect of atmosphere, air outside a furnace body enters the cavity through an air inlet pipe and enters the position of the furnace mouth through the air inlet holes. Inflammable gas like carbon monoxide and inflammable solid like coal dust are further burned under the aerobic condition, coal burning rate is improved, energy sources are saved, air pollution is reduced, the heating furnace gasifying ring is formed by casting integrally, and the service life is greatly prolonged.

Description

Heating stove gasification circle

Technical field

The utility model belongs to stove and accessory accessory technical field, relates to heating stove gasification circle concretely.

Background technology

In a lot of rural areas of northern China, cook and warming generally adopts the fire coal radiator of cooking a meal, in the coal burning process, the radiator fault of construction because existing fire coal is cooked a meal, primary combustion time burning is insufficient in burner hearth, and part not have the conny of burning and carbon monoxide that burning produces etc. with the hot gas discharge, has not only reduced the coal heat conversion, the energy is caused waste, but also can cause air pollution.For sufficient combustion, the gasification circle is set at the fire door place, the gasification circle that uses is ring cap shape at present, be buckled in the bell top, form air cavity with bell, be positioned at fire door one side and have air admission hole, there is following defective in this gasification circle: one, service life is short, its two, the air cavity seal is poor, be difficult to form negative pressure in air cavity, cause the air inlet weak effect, still have the inadequate defective of burning.

The utility model content

The technical problem that the utility model solves just provides that a kind of long service life, air inlet are effective, the heating stove gasification circle of sufficient combustion, energy savings.

For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: comprise the ring-type circle body that has at least one air inlet pipe, described ring-type circle body comprises housing and the cavity that is communicated with described air inlet pipe, is provided with a plurality of air admission holes at described housing near ring-type circle body inboard.

Its additional technical feature is:

Described air inlet pipe is two;

Described ring-type circle body is circular or oval ring-type;

Described ring-type circle body is the regular polygon ring-type;

On described ring-type circle body, be provided with positioning convex ring near the inboard.

The heating stove gasification circle that the utility model provides, compare with prior art and to have the following advantages: one, owing to comprise the ring-type circle body that has at least one air inlet pipe, described ring-type circle body comprises housing and the cavity that is communicated with described air inlet pipe, be provided with a plurality of air admission holes at described housing near ring-type circle body inboard, during use, this heating stove gasification circle is placed on the fire door position, the carbon dioxide that burning produces in the burner hearth, gas such as carbon monoxide and conny etc. are in flow process upwards, form negative pressure at the fire door place, air outside the body of heater is under atmospheric effect, enter cavity through air inlet pipe, enter the fire door place through air admission hole again, flammable solids such as fuel gas such as carbon monoxide and conny are further burning under aerobic conditions, has not only improved the coal burning rate, saved the energy, and reduced pollution to air, and heating stove gasification circle forms for integrally casting, and prolong service life greatly; Its two because described air inlet pipe is two, the air inlet better effects if; Its three because described ring-type circle body is that circular or oval ring-type or described ring-type circle body are the regular polygon ring-type, the air inlet better effects if, it is more abundant to burn; Its four owing on described ring-type circle body, be provided with positioning convex ring near the inboard, can directly positioning convex ring be stuck in the fire door inboard, use convenient.

Description of drawings

Fig. 1 is the structural representation of heating stove gasification circle;

Fig. 2 is A-A cutaway view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1;

Fig. 4 is the structural representation of the heating stove gasification circle of regular hexagon ring-type circle body;

Fig. 5 is the structural representation of the heating stove gasification circle of elliptical annular circle body.

The specific embodiment

The structure of the heating stove gasification circle that the utility model is proposed below in conjunction with accompanying drawing is described further.

As depicted in figs. 1 and 2, the structural representation that encloses for the heating stove gasification.Its structure comprises the ring-type circle body 2 that has at least one air inlet pipe 1, and ring-type circle body 2 comprises housing 3 and the cavity 4 that is communicated with air inlet pipe 1, is provided with a plurality of air admission holes 5 at housing 3 near ring-type circle body inboard.During use, this heating stove gasification circle is placed on the fire door position, the carbon dioxide that burning produces in the burner hearth, gas such as carbon monoxide and conny etc. are in flow process upwards, form negative pressure at the fire door place, air outside the body of heater is under atmospheric effect, enter cavity 4 through air inlet pipe 1, enter the fire door place through air admission hole 5 again, flammable solids such as fuel gas such as carbon monoxide and conny are further burning under aerobic conditions, not only improve the coal burning rate, saved the energy, and reduced the pollution to air, heating stove gasification circle back integrally casting forms, and prolong service life greatly.

Air inlet pipe 1 is preferably two, air inlet better effects if like this.Certainly, air inlet pipe 1 can be one, also can be for more than two.

As shown in figures 1 and 3, the shape of ring-type circle body 2 can be for circular.As shown in Figure 4, the shape of ring-type circle body 2 can be the elliptical ring shape.As shown in Figure 5, the shape of ring-type circle body 2 also can be the regular polygon ring-type, the air inlet better effects if, and it is more abundant to burn.Certainly, ring-type circle body 2 also can be other shapes.

On ring-type circle body 2, be provided with positioning convex ring 6 near the inboard, can directly positioning convex ring be stuck in the fire door inboard, use convenient.

Protection domain of the present utility model not only is confined to above-described embodiment, as long as structure is identical with the utility model heating stove gasification coil structures, just drops on the scope of the utility model protection.
