Abstract

The utility model discloses a multipurpose boiler. The multipurpose boiler is provided with a work table, a chimney and an outer wall; the periphery of an internal hearth is provided with a double-layer water tank; a retainer ring is arranged between the double-layer water tank and a fire hole; one side of the retainer ring, near the chimney, is provided with a smoke inlet; an annular upper clapboard and an annular lower clapboard are arranged between the double-layer water tank and the outer wall; one side of the upper clapboard, far away from the chimney, is provided with an air gate; on the outer wall, an auxiliary channel communicated to the chimney is arranged between the upper clapboard and the lower clapboard; and an air valve is arranged near the root part of the chimney. The structure enables the heat of smoke gas in a burning chamber to be absorbed fully; through measurement, the temperature of the smoke gas discharged into the chimney is obviously lower than that of the boiler in the prior art; the heat consumption is remarkably reduced; the operation is convenient; and the manufacturing cost of the structure is low.

Description

A kind of multipurpose boiler

Technical field

The utility model relates to a kind of boiler, specifically a kind of boiler with purposes such as heating, heat supplies.

Background technology

At present, vast rural area also is being widely used domestic boiler in the north, and these boilers have been said the heating and the two kinds of functions of cooking from purposes; Its mechanism generally is that specific flue is set; The place of flue approach is provided with water tank then, thereby with the water heating, utilizes water, vapour to reach the purpose of heating; In addition heating boiler is provided with the cooking function simultaneously, has made things convenient for the multiple use of family.Existing multiduty boiler is being done a lot of trials aspect flue design, the Btu utilization; Multiple internal structure has appearred; Make the capacity usage ratio of boiler increase; The environmental protection degree makes moderate progress, but owing to the reasons such as structural design of its flue, existing boiler in use also exists significant thermal losses.Can not well take into account such as the heating and the function of cooking, the exhaust opening temperature is high excessively.

The utility model content

The purpose of the utility model is the deficiency that overcomes prior art, and a kind of improvement back boiler is provided, and makes its Btu utilization abundant, have cook, function such as heating, and cheap for manufacturing cost.

For solving the problems of the technologies described above, a kind of multipurpose boiler of the utility model is provided with workbench, chimney and outer wall; Be provided with double-layer tank around its inner burner hearth, between the internal layer of this double-layer tank and the skin arranged communicating pipe, said double-layer tank also is provided with water inlet pipe and outlet pipe; It is characterized in that: be provided with back-up ring between said double-layer tank top and the burner; This back-up ring is provided with into mouth near chimney one side, between double-layer tank and outer wall, is provided with the upper spacer and the lower clapboard of annular, and the side away from chimney on the said upper spacer is provided with valve; Between upper spacer and lower clapboard, be provided with the passage that attaches that passes to chimney on the said outer wall, be provided with air valve near the chimney root.

Said double-layer tank bottom is provided with a slag-drip opening, and this slag-drip opening stretches out from outer wall.

After adopting such scheme, the gas fume of combustion chamber heat is fully absorbed, through measuring, the flue-gas temperature that enters in the chimney is starkly lower than boiler of the prior art, has significantly reduced thermal losses, and is easy to operate, and this structure fabrication cost is lower in addition.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

Fig. 1 is the structural representation of a kind of multipurpose boiler of the utility model.

The specific embodiment

As shown in Figure 1; A kind of multipurpose boiler of the utility model is provided with workbench 1, chimney 15 and outer wall 12, is provided with double-layer tank 7 around its inner burner hearth 10; Communicating pipe 8 is arranged between the internal layer of this double-layer tank 7 and the skin; Said double-layer tank 7 also is provided with water inlet pipe 6 and outlet pipe 16, and it is characterized in that: be provided with back-up ring 18 between said double-layer tank 7 tops and the burner, this back-up ring 18 is provided with into mouth 17 near chimney 15 1 sides; Between double-layer tank 7 and outer wall 12, be provided with the upper spacer 3 and lower clapboard 4 of annular; Side away from chimney 15 on the said upper spacer 3 is provided with valve 2, between upper spacer 3 and lower clapboard 4, be provided with on the said outer wall 12 pass to chimney 15 attach passage 14, be provided with air valve 13 in the flue collector of chimney 15 roots.

Double-layer tank 7 bottoms are provided with a slag-drip opening 11, and this slag-drip opening 11 stretches out from outer wall 12.Stove is put 9 and is provided with the handle that stretches out outer wall 12.Stove is put 9 and is used to become flexible, control the slag in the burner hearth 10.

During use, water gets into from water inlet pipe 6, and water can flow freely in double-layer tank 7, is flowed out by outlet pipe 16 at last.

When not cooking, close valve 2, flue gas gets into the N shape flue that is made up of double-layer tank 7 and furnace wall 2 through combustion chamber 1, goes out from the flue collector of chimney then, is provided with the switch that air valve 13 is used to control flue collector in the flue collector.When needs were cooked, kitchen range are opened and placed to burner 19, opens valve 2; The flue gas place from above-mentioned passage through outside; Can also from advance mouth 17 through valve 2, attach passage 14 and get into chimneys 15, in this passage, advance mouth 17, valve 2, attach the both sides that passage 14 is positioned at double-layer tank 7 successively; Farthest increase the stroke of flue gas, improved the utilization rate of heat.
