The circumference of the outer cylinder surface of the stove core is a heat insulation layer. The outside of the heat insulation layer is a round annular cavity. The inner of the cavity is a coiled pipe. The stove body on the outside of the cavity is provided with a flue inside. The upper part of the flue is communicated with the bottom of the cavity, and the upper end is communicated with the annular flue of a stove cover. The utility model has the advantages that the utility model has large heated area and high heat efficiency, the utility model is especially suitable for stove cores with large diameters, the fire of the utility model can be damped down easily and can not be extinguished, etc.

Description

Coiled-pipe backfire type heating-cooking two-purpose stove

The utility model relates to a kind of heating-cooking dual-purpose stove.

At present, the kind of heating stove is more, but structure is similar, for example the higher rich board stove of Tsing-Hua University China of the thermal efficiency on the market becomes the board stove with the Tianjin treasured, its heat exchange mainly is the water jacket in the stove, water jacket is above combustion chamber, because water jacket is height-limited, need many heats to be not fully utilized, there is the heat of radiation in the combustion chamber also just to waste again, though thermal efficiency ratio system stove height, but heat utilization efficiency is still lower, and than traditional stove height, changes coal and be not easy, it is unfit to do the major diameter honeycomb briquette, and reason one is that furnace height increases; The 2nd, radiator is hung De Taigao, will directly influence the hot and cold water circulation, reduces the thermal efficiency.

It is big that the purpose of this utility model is to design a kind of heating surface area, and thermal efficiency height can be made the heating-cooking dual-purpose stove of major diameter honeycomb briquette stove.

The utility model is achieved in that the middle part of body of heater is a combustion chamber, combustion chamber is sitting on grate, around the combustion chamber external cylindrical surface is heat-insulation layer, heat-insulation layer is outward the cavity of annular, it in the cavity coil pipe, the import and export of coil pipe are stretched out outside the body of heater, in the body of heater outside the above-mentioned cavity flue is arranged, flue communicates with the bottom of above-mentioned cavity, the top of flue communicates with annular flue around the bell, and there is stove trunk of funnel mouth the upper surface of annular flue, and the outer middle part of bell is the ring collar that the envelope cigarette is used, interior middle part is the fire-suppressing cover of heating usefulness, and the outermost layer of body of heater is heat-insulation layer and stove outer covering.

The utility model compared with prior art has following advantage: 1) because combustion chamber and thermoreceptor---and heat-insulation layer is arranged between the coil pipe, so the thermoreceptor of low temperature do not influence burning of coal temperature in the combustion chamber, improved the utilization rate and the efficiency of combustion of coal; Be easy to bank up a fire and do not put out a fire.2) wall of coil pipe is all heating surface, and heating surface area is big, and the heat transfer efficiency height is an example with 120 millimeters honeycomb briquette heating stoves, and heating surface area of the present utility model is 4.1 times of magnificent rich board stove water jacket heating surface area, is to protect into 2.4 times of board stove; 3) coil pipe helps the Natural Circulation of hot and cold water, can significantly reduce the incrustation scale that produces when non-demineralized water heats; 4) can do large diameter honeycomb briquette stove, the height of stove is not subjected to the influence of coil pipe, need not heighten the height of radiator yet.

Be elaborated below in conjunction with accompanying drawing.

Fig. 2 is the utility model vertical view;

Fig. 3 is an A-A cutaway view among the utility model Fig. 2;

Fig. 4 is a B-B cutaway view among the utility model Fig. 3.

The middle part of body of heater 6 is combustion chambers 14, and combustion chamber 14 internal diameters can be 150cm-350cm, and combustion chamber 14 can be put into honeycomb briquette, and combustion chamber 14 is suitable for reading fire sealing cover 10, and combustion chamber 14 end openings are sitting on grate 13, and grate is an ash bucket 17 13 times.Around combustion chamber 14 external cylindrical surfaces is heat-insulation layer 12, and heat-insulation layer 12 is the interior bucket courage that not saturating steel sheet forms, and fills real rock wool in the interior bucket courage.Its effect is to guarantee the honeycomb briquette normal combustion; The seat clay combustion chamber 14 that protection is easily split, the service life of increase combustion chamber 14.Outside the heat-insulation layer 13 is the cavity 18 of circular ring type, is coil pipe 11 in the cavity 18, and the import and export of coil pipe 11 are stretched out outside the body of heater 6, and its port has gas thread, is used for linking to each other with the pipeline of warming oneself.There is cleaning door 19 lower end of cavity, and the upper end communicates with combustion chamber 14 inner chambers.In the body of heater 6 outside the above-mentioned cavity 18 flue 7 is arranged, flue 7 communicates with the bottom of above-mentioned cavity 18, and the top of flue 7 communicates with bell 1 annular flue 8 all around, and there is stove trunk of funnel mouth 2 upper surface of annular flue 8.The outer middle part of bell 1 is the annular collar 20 that the envelope cigarette is used, and interior centre is the fire-suppressing cover 9 of heating usefulness, and the outermost layer of body of heater 6 is heat-insulation layer 16 and stove outer covering 15, and heat-insulation layer 16 can be used light fire brick.

When heating, cover fire-suppressing cover 9 and top cover circle 20, at this moment showing tremendous enthusiasm flue gas up can't pass through, and under the effect of flue 7 suction, showing tremendous enthusiasm flue gas is by the cavity 18 at coil pipe 11 places between inside and outside bucket courage, enters the annular flue 8 of body of heater 6 flues 7 and bell 1 and discharges.Water in the coil pipe 11 is realized heating by continuous heat cycles in this course.When cooking, take away ring collar 20 and fire-suppressing cover 9, because coal apex distance Container for cooking bottom is nearer, and at this moment showing tremendous enthusiasm flue gas can not move downward, and can use as common stove cooking.
