Abstract

The utility model is the improvement of a household water-heating stove. 4-8 triangle heat absorbing slices are welded in a barrel-shaped stove core, and the refractory heat-insulating material is filled between the heat absorbing slices; the position between the stove core and a stove body and the periphery of a flue are provided with three circulating water jackets, wherein, the upper water jacket and the lower water jacket of the periphery of the flue are respectively communicated with a heater on a stove mouth. The utility model has thick hearth insulating layer, high temperature of the stove interior and high thermal efficiency; the circulating water can absorb the heat quantity by the heat absorbing slices, the flue wall and the heater, which ensures high utilization rate and can not influence the hearth temperature. The utility model has simple structure, easy fabrication, steel and energy saving.

Description

Household water-heating stove

The utility model is the improvement to the service water radiator.

At present, the kind of service water radiator is more, for improving the thermal efficiency, the structure of design becomes increasingly complex, and the steel consumption amount is big, cost is relatively also higher, the various service water radiators of selling on the market, structurally common point is that hearth wall is thinner, the burner hearth periphery is a cyclic water jacket, owing to " icing " phenomenon of recirculated water causes that burner hearth internal combustion temperature is low, the thermal efficiency hangs down the requirement that can not satisfy the user when heating and supplying water.

For avoiding above-mentioned weak point, the purpose of this utility model is to provide a kind of service water radiator, the thickness of thickening hearth wall, the combustion temperature in hearth height, thermal efficiency height, simple in structure, the volume trifle is economized steel and fuel, and quick heating when heating and supplying water satisfies user's requirement.

For achieving the above object, the utility model adopts following technical measures.

The service water radiator is made up of body of heater, stove seat, flue, stone or metal plate for standing a stove on as a precaution against fire, fire grate, flue, water jacket, difference is that flue is a cylindrical shape, be sleeved in the body of heater, be welded with 4～8 triangle heat absorbing sheets along inboard wall of furnace, between the triangle heat absorbing sheet, fill up flame-proof thermal insulation material, heat recirculated water in the big burner hearth in young bottom on the formation, stove is positioned at flue, the peripheral water jacket of flue.Be provided with movably heater on fire door top.

Above mentioned heat recirculated water water jacket is totally three compositions, constitute first cyclic water jacket between body of heater and the flue, and be connected with the lower water jacket of flue periphery, the water jacket of the peripheral bottom of flue is second cyclic water jacket, communicate through the heater of pipeline with fire door top, the outlet pipe of heater communicates through the peripheral upper water sleeve of flexible pipe and flue, and the peripheral upper water sleeve of flue is the 3rd cyclic water jacket.The recirculated water water inlet is positioned at the body of heater bottom, and delivery port is located on the 3rd cyclic water jacket.

Owing to adopted above structure, the utility model is compared with the prior art as follows than advantage:

1, simple in structure, save steel, make easy.

2, adopted the heat absorbing sheet structure, thickeied the heat-insulation layer of burner hearth, and three cyclic water jackets all absorb flue and flue ambient heat the heat utilization efficiency height.

3, easy to use, fuel saving, thermal efficiency height.

In order to further specify characteristics of the present utility model, the embodiment below in conjunction with shown in the accompanying drawing 1 is described in detail.

Fig. 1 service water radiator structural representation.

Among the figure: 1 stove seat, 2 triangle heat absorbing sheets, 3 flues, 4 bodies of heater

5 fire doors, 6 stone or metal plate for standing a stove on as a precaution against fires, 7 heaters, 8 flexible pipes, 9 delivery ports

10 flues, 11 flue upper water sleeves, 12 road lower water jackets

13 water jackets, 14 water-fast insulation material 15 fire doors

As shown in Figure 1, evenly being welded with leg-of-mutton heat absorbing sheet 2 on the flue 3, filling up flame-proof thermal insulation material 14 between the heat absorbing sheet, is water jacket 13 between body of heater 4 and the flue 3, and flue 10 peripheries are provided with upper water sleeve 11, and lower water jacket 12 communicates with heater 7 through flexible pipe 8 respectively.During the utility model work, emit heat after the burner hearth fuel combustion, the triangle heat absorbing sheet directly absorbs heat and transmits flue, the heat transferred flue of while heat-insulation layer, make water temperature rising in the water jacket, because heat-insulation layer is thicker, water temperature is little to the fire box temperature influence, thereby the stove fuel combustion is complete, the temperature height, thermal efficiency height, the water after absorbing heat around the flue, the back rising that heats up enters the lower water jacket of flue periphery, further absorbs the heat that flue is kept away radiation.The recirculated water of being heated enters heater by the delivery port of lower water jacket through flexible pipe, heater is positioned at the fire door top, temperature in the stove is directly passed to heater, water temperature is further raise, enter the flue upper water sleeve by flexible pipe again, after absorbing the waste heat of flue gas, enter in the radiator or the use of heat supply water by the delivery port outflow.The cold water of being returned by radiator enters water jacket again by the body of heater water inlet.Finish heating.When need are made the cooking stove, heater is moved one side get final product, because recirculated water heats up by the triangle heat absorbing sheet, be provided with thicker heat-insulation layer in the burner hearth simultaneously, circulating water temperature is less to the stove fire influence, thereby easily banks a fire, and quick heating.Water temperature can reach about 85 ℃ in the fin through testing about one hour, during optimum state in the fin water temperature can reach 100 ℃, indoor quick heating reaches the purpose of heating.

The service water radiator is simple in structure, and is easily manufactured, also can be with existing common heating stove, and to change a social system and be the hot-water heating stove, cost is low.

The utility model can be made into series of products, and for the demand of different heating areas, outline specification is as follows:

Flue: high 320～400mm, diameter: 320～400mm,

Furnace diameter: 340～420mm,

Furnace port diameter: 110～140mm.
