Abstract

The utility model belongs to the domestic heating equipment and relates to a double water flow heat-exchange type heating stove comprises a stove body, a stove head, a top cover, a bottom plate, an ash discharge bucket, a water jacket, a water jacket bracket, a stove tile and an annealing cap which can adjust a ventilation hole. The double water flow heat-exchange type heating stove is specifically characterized in that the water jacket with a sandwich type on the cylinder surface is connected and welded with a spiral tube heat exchanger in parallel, and a fire conducting ring and a fire holding cap are provided above the spiral tube. The solution has two heat exchangers, and the utility model has advantages of improved heat efficiency, convenient operation and stable performance under the function of the annealing cap and the fire holding cap.

Description

Double water flow heat-exchange type heating stove

The utility model belongs to domestic heating equipment, the structure of its a kind of improved novel heating stove.

In recent years along with the rapid raising of people's material life, the improvement development of the living facilities in the family is very fast, aspect heating, the stove of general direct burning coal heating can not satisfy, heating stove at the small-sized burning coal of the local a kind of centralized operation dispersed supply of heating that does not have the central heating condition arises at the historic moment, and kind is many, the development fast.The inventor had once invented a kind of aluminium matter water jacket fire guiding type domestic heating stove in 92204168.7 patents in March, 92, it also has except that having multiple uses such as heating, cooking, heat supply, and water jacket is in light weight, heat exchange effect good, maneuverable advantage, is a kind of pattern of comparatively ideal heating stove.But through use and observe after find to still have some need improve the leeway of raising.

The purpose of this utility model is further to improve the deficiency of aforementioned 92204168.7 patents, improves its performance, make easy to operate and further improve the effect of heat exchange, so this programme is the counterpart of preceding patent.

By as above design, two current heat exchange type heating stoves that this programme provided include body of heater, base plate, burner, the multiple combined-type top cover, face of cylinder sandwich type water jacket, the water jacket bracing frame, insulation material, fire grate, interior tile, go out ash bucket, the anneal lid in the c /v hole of two compositions, its concrete feature is: on stove inner cylinder face sandwich type water jacket heat exchanger also in parallel one with its concentric face of cylinder spiral tube exchanger, the upper inside wall conducting of the upper end of helix tube and water jacket and welding, the inwall conducting at its lower end and water jacket middle part and welding, one fire guiding ring is arranged above helix tube, it is supported by a plurality of cantilever on the water jacket inwall, can place on the fire guiding ring epirelief indent and on the circular fire-suppressing cover of drop handle is arranged, the external diameter of its fire-suppressing cover covers the aperture of endoporus greater than the aperture of fire guiding ring less than the anneal of burner.

Adopt this programme can embody following superiority: 1. except that being provided with face of cylinder intercalated water sleeve again increase spiral tube exchanger is set, heat exchange area is multiplied, the distance of spiral in-pipe flow is long, the time of heating is long, and be in the highest temperature region in the stove, therefore can fully absorb the heat of coal fire, improve the thermal efficiency; 2. set up fire guiding ring and fire-suppressing cover above helix tube, can control flare and skim over the inwall that helix tube jumps on water jacket, the air vent that limits through anneal lid passes burner and discharges through flue again, and furnace heat uses fully; Open top cover when 3. making meal, anneal lid and fire-suppressing cover make coal fire directly rush at the bottom of a pan, easy and simple to handle; 4. simple in structure and standardization is convenient to make in batches promote the use of.

Fig. 1 is the section of structure of the two current heat exchange type heating stoves of this programme.

Fig. 2 is the situation that this heating stove is done the cooking time spent.

The structure and the course of work of existing accompanying drawings this programme heating stove.Burner (3), multiple combined-type top cover (1), (2), body of heater (10), insulation material (14), fire grate (16), interior tile (12), go out ash bucket (17), base plate (18), the anneal lid (4) in the c /v hole of water jacket bracing frame (13) and two compositions, (5) identical with preceding patent, its water jacket (9) is a face of cylinder sandwich type, it is placed on the bracing frame (13), the water inlet pipe and water outlet pipe that water jacket is arranged at the rear of body of heater, spiral tube exchanger (8) is being welded in the inside parallel connection of water jacket, on the inwall on water jacket top, be welded with the multiple spot cantilever support and fire guiding ring (7), on fire guiding ring (7), can place the fire-suppressing cover (6) of the band drop handle of an epirelief indent.

The coal of this heating stove is in the tile internal combustion, can keep the temperature in the combustion zone can distribution loss very not fast, flare and flue gas are emerged behind the tile, under the control of fire-suppressing cover, laterally skim over helix tube and jump on the water jacket inwall, again can very fast loss under the air vent control of anneal lid, helix tube is a main heat exchanger, behind its unfolded surface greater than the inner surface heat exchange area of water jacket, increased spiral tube exchanger and can directly accept the heat exchange that the width of cloth is penetrated form in the high-temperature region, the distance that water flows in helix tube is long, the time of heating is long, can improve 15% than the coefficient of heat transfer of VERTICAL TUBE.Therefore the sample of this programme proves thermal efficiency height through operation test, stable performance, and advantage easy for operation is arranged.

Claims

1, a kind of pair of current heat exchange type heating stove, it includes body of heater (10), base plate (18), burner (3), multiple combined-type top cover (1) (2), face of cylinder sandwich type water jacket (9), water jacket bracing frame (13), insulation material (14), fire grate (16), interior tile (12), go out ash bucket (17), anneal lid (4) (5) in the c /v hole of two compositions, it is characterized in that in the sandwich type water jacket heat exchanger of the face of cylinder face of cylinder spiral tube exchanger (8) concentric also in parallel with it, the inwall conducting on the upper end of helix tube and water jacket top and welding, the inwall conducting at its lower end and water jacket middle part and welding, one fire guiding ring (7) is arranged above helix tube, it is supported by a plurality of cantilever on the water jacket inwall, can place above the fire guiding ring epirelief indent and on drop handle is arranged the external diameter of its fire-suppressing cover of circular fire-suppressing cover (6) greater than the aperture of fire guiding ring, less than the aperture of the anneal lid endoporus of burner.
