Abstract

The utility model discloses a drive-through type double-loop gas firing furnace and solves the problem of lower burning efficiency of prior furnace, comprising an outer casing, an air inlet connector is arranged on the outer casing, and an outer-loop cover plate and an inner-loop cover plate are arranged on the upper part of the outer casing. The utility model is characterized in that: a gas distribution guider is arranged between the two cover plates; an annular clearance exists between the outer-loop cover plate and the outer casing to form an out-loop fire ring gas orifice; an annular clearance exists between the inner-loop cover plate and the gas distribution guider to form an inner-loop fire ring gas orifice. The utility model has the advantages that: as the annular clearance is taken as the gas orifice, the inner-loop fire and the outer-loop fire are upward and in parallel when burning, and attracted mutually, thus the flame is more continuous, centralized and stable; the gas guider in the furnace not only eliminates the phenomenon of vortex flow, but also makes the distribution of the gas more evenly and burns fully and distributes automatically the inner-loop gas and the outer-loop gas, thus the burning efficiency is improved and the energy consumption is reduced. What is more, the utility model is simple in structure and convenient in use.

Description

Through dicyclo fire gas stove tool

Technical field

The utility model relates to a kind of through dicyclo fire gas stove tool of using of being suitable on various gas-cookers.

Background technology

In the prior art, gas-cooker has many kinds, and the stove and accessory on the gas-cooker also has nothing in common with each other, monocycle stove tool is arranged, dicyclo stove tool is also arranged, but, all be to constitute by base and loam cake no matter be that monocycle stove tool or its basic structure of dicyclo stove tool are similar, base adopts cast iron to make more, an annular opening is arranged on base, and loam cake is an annular, is installed in the annular opening of base, loam cake is provided with the combustion gas through hole, and the combustion gas through hole is distributed on the inner ring and outer ring of loam cake.Owing between the combustion gas through hole certain distance is arranged all, so the flame on each combustion gas through hole also is relatively independent, therefore, the firepower during burning is concentrated inadequately, and efficiency of combustion is lower; In addition, do not have gas-guiding structure in the stove and accessory, combustion gas makes the combustion gas skewness, and then causes the flame temperature inequality at the inner eddy current that forms easily of stove and accessory, has reduced efficiency of combustion.

The utility model content

The technical problems to be solved in the utility model is, overcomes the existing low problem of stove and accessory efficiency of combustion, and a kind of efficient, energy-conservation through dicyclo fire gas stove tool is provided.

The utility model has a shell, on shell, be connected to inlet suction port, outer shroud cover plate and interior ring cowling plate are housed on the top of shell, its special character is, gas is housed between ring cowling plate and the interior ring cowling plate outside distributes guider, an annular gap is arranged between ring cowling plate and the shell outside, constitute outer shroud fire ring shape gas jet orifice, between interior ring cowling plate and gas distribution guider, an annular gap is also arranged, ring fire annular fuel gas spray orifice in constituting.

On inlet suction port, also be connected to secondary air joint and an air intake joint, air is incorporated in the combustion gas.

Advantage of the present utility model is, adopt the annular gap as gas jet orifice, make flame more continuous, concentrated and stable, and the gas director in the stove and accessory had both been eliminated vortex phenomenon, make being more evenly distributed of combustion gas again, and internally encircle combustion gas and the outer shroud combustion gas distributes automatically, the pressure of ring combustion gas and outer shroud combustion gas remains balance in making, air intake joint and secondary air joint not only are incorporated into air in the combustion gas, also make combustion gas and Air mixing more even, thereby improved efficiency of combustion, reduced the consumption of the energy, and reduced content of harmful in the waste gas, avoided stove and accessory knot carbon; In addition, interior ring fire is parallel with outer ring fire upwards to attract each other during burning, makes firepower more concentrated, and it is more abundant to burn, and the temperature of flame is also higher, and simple in structure, and is easy to use.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

The specific embodiment

As shown in drawings, the utility model has a shell 1, and shell 1 is a drum shape, is connected to inlet suction port 8 on shell 1, and inlet suction port 8 is positioned in the middle of the bottom of shell 1, between the two for being threaded; Outer shroud cover plate 2 and interior ring cowling plate 5 are housed on the top of shell 1, the bottom of outer shroud cover plate 2 is conical openings, avoids combustion gas to produce eddy current herein, on the sidewall at ring cowling plate 2 middle parts several ventholes 3 is arranged outside, venthole 3 evenly is provided with, and the outer shroud combustion gas is evenly distributed; On the top of interior ring cowling plate 5 handle 4 is housed, is convenient to take off cleaning, the bottom of interior ring cowling plate 5 is a cone, combustion gas had guide effect, several ventholes 6 are arranged on the planar annular at interior ring cowling plate 5 middle parts, and venthole 6 evenly is provided with, and the ring combustion gas evenly distributes in making; Gas is housed between ring cowling plate 2 and the interior ring cowling plate 5 outside distributes guider 7, it is conical that gas distributes the bottom of guider 7, there is an air admission hole 17 centre of circular cone, because the diameter of air admission hole 17 is less, combustion gas distributes at air admission hole 17 places, part combustion gas encircles blast tube in air admission hole 17 enters into, another part combustion gas then enters into the outer shroud blast tube, the ring blast tube distributes the conical inner surface of guider 7 bottoms to constitute by the cone and the gas of interior ring cowling plate 5 bottoms in described, should interior ring blast tube be the annular taper shape that increases gradually, combustion gas had guiding and distributional effects, make being more evenly distributed of combustion gas, and avoid eddy current to produce; Described outer shroud blast tube is distributed the conical external surface of guider 7 bottoms and the cone shaped opening of outer shroud cover plate 2 bottoms to constitute by gas, this outer shroud blast tube is the annular taper shape that reduces gradually, and combustion gas is led and distributed; An annular gap 18 is arranged between ring cowling plate 2 and the shell 1 outside, constitute outer shroud fire ring shape gas jet orifice, between interior ring cowling plate 5 and gas distribution guider 7, an annular gap 19 is also arranged, ring fire annular fuel gas spray orifice in constituting; On inlet suction port 8, also be connected to secondary air joint 9 and an air intake joint 14, air is incorporated in the combustion gas; Inlet suction port 8 links together with secondary air joint 9, for easy to assembly, the profile of secondary air joint 9 is a regular hexahedron, a fresh air inlet 10 is all arranged on each face of its regular hexahedron, on the transverse end surface of secondary air joint 9, also have several fresh air inlets 11, introduce enough air by fresh air inlet 10 and fresh air inlet 11; Described secondary air joint 9 is connected with an air intake joint 14 with taper joint 13 by elbow 12, and several fresh air inlets 15 are arranged on the transverse end surface of an air intake joint 14, introduces air under the effect of combustion gas; One time air intake joint 14 is connected with Gas Pipe 16, and combustion gas is introduced in the stove and accessory.
