The utility model is characterized in that the flat circular hearth is communicated with the flue which is arranged at one side of the upper part of the hearth, and is shaped with the flue in the casting way. The utility model has the advantages of fast temperature rise, high temperature, quick cooling, permanent constant temperature, smooth fume discharge without back smoke, benefit for ventilation and dust falling, sufficient coal combustion, benefit for environmental sanitation, high thermal efficiency, coal saving to more than 37 per cent, good integrity, and convenient carry and transport. Besides, the utility model can use various miscellaneous coal as fuels, and therefore, the utility model is especially suitable for rural areas to use.

Description

The high temperature big chamber stove of economizing on coal

The utility model relates to a kind of domestic stove, particularly a kind of high temperature that warming uses big chamber stove of economizing on coal that is suitable for.

In vast rural area, the indoor heater unit of not installing as yet such as overwhelming majority resident, school, grass-roots unit, middle-size and small-size industrial and commercial enterprises, warming is still based on common stove and accessory, traditional cast iron stove mostly is the stretched moulding, burner hearth must be warded off interior cover with earth, otherwise coal can not fully burn in stove, and flare forms not prosperous, is not easy to keep constant temperature.The flue outlet of tradition cast iron stove is below the stone or metal plate for standing a stove on as a precaution against fire baseplane, and the flue outlet position is low must to influence smoke evacuation, exports lowly more, influences seriously more, and all there is anti-cigarette problem in nearly all traditional cast iron stove under the lower situation of ambient pressure.And traditional fire grate exists improper ventilation, and easily the formation dead angle of not firing causes baked wheaten cake not prosperous, the drawback that coal burning is insufficient and the ash difficulty influence that falls is ventilated.Traditional in sum stove and accessory causes many difficulties to warming, has both wasted fuel, and the effect of heat release is bad again, can not reach economize on coal, the effect of high temperature.

The purpose of this utility model is to provide a kind of quick heating, temperature height, rapid heat dissipation, thermal efficiency height, the lasting high temperature of the constant temperature big chamber stove of economizing on coal.

The purpose of this utility model is achieved in that a kind of high temperature big chamber stove of economizing on coal, comprise flue, flue outlet, stone or metal plate for standing a stove on as a precaution against fire, burner hearth, fire grate, fire door, stove seat, the burner hearth that it is characterized in that oblate type communicate with the flue of upper furnace one side and with the flue integral casting forming; Flue outlet is higher than stone or metal plate for standing a stove on as a precaution against fire; Stone or metal plate for standing a stove on as a precaution against fire can be round or square.The diameter of two ends up and down of burner hearth is 1: 1.5 with middle bulging maximum gauge ratio.

The utility model has improved traditional body of heater moulding, fire grate thickness, flue outlet position and fire grate moulding, compared with prior art, has following good effect:

1. quick heating, the temperature height, rapid heat dissipation, constant temperature is lasting, makes body of heater reach the exothermic maximum amount in the shortest time and keeps the highest constant temperature.

2. need not use earth in the inboard wall of burner hearth interplanting, easy to use.

3. the not anti-smoothly cigarette of smoke evacuation can not cause the waste of body of heater waste heat.

4. help ventilating and the ash that falls, coal is fully burnt, reduce air pollution, help environmental sanitation, be beneficial to health.

5. thermal efficiency height is economized on coal more than 37%.

6. handsome in appearance, good integrity, volume is little, and is in light weight, easy to carry and transport.

7. simple in structure, reasonable in design, various assorted coals all can draw and are fuel, reduce fuel cost and purchase the annex expense, are particularly suitable for using at agricultural material.

The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment:

Consult Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the high temperature big chamber stove of economizing on coal mainly is made of flue outlet 1, flue 2, fire door 3, stone or metal plate for standing a stove on as a precaution against fire 4, burner hearth 5, fire grate 7, fire door 8, stove seat 9, bell 10 etc., its burner hearth 5 is thick oblate type between the detail of two ends up and down, and burner hearth 5 communicates with the flue 2 of burner hearth 5 tops one side and adopt the metal material integral casting forming with flue 2, and this example can be selected the moulding of HT150 iron casting for use.The upper end of burner hearth 5 is fire doors 3, and the lower end is a stove seat 9, is stone or metal plate for standing a stove on as a precaution against fire 4 on the fire door 3, joins with plane on the flue 2, and all with burner hearth 5 integral casting formings, stove seat 9 one sides have fire door 8, is used for ventilating and the ash that falls, and 9 of burner hearth 5 and stove seats are provided with movable furnace grate 7.The diameter of two ends up and down of burner hearth 5 is 1: 1.5 with middle bulging maximum gauge ratio, and this ratio can make the fuel value of coal reach the optimum value that surmounts the plain cast iron stove, fully burning, reach economize on coal, the optimum efficiency of high temperature.Furnace wall 6 thickness of burner hearth 5 and the ratio of burner hearth 5 volumes are 8 ± 3mm: 0.006m ³, casting just can make body of heater reach maximum thermal discharge in the shortest time and keep the highest constant temperature according to this, and does not need to ward off interior cover with earth at inboard wall of burner hearth.The flue outlet 1 of its flue 2 upper ends is higher than stone or metal plate for standing a stove on as a precaution against fire 4, and several sections and bell can make coal smoke discharge smoothly on a plane, and not anti-cigarette, the optimum size of flue 2 not only can guarantee that logical cigarette smoothly but also can not cause the waste of body of heater waste heat.

Consult shown in Figure 5, fire grate 7 moulding are oval type, put into the gap≤10mm of burner hearth 5 and furnace wall 6, could be fit to domestic consumer like this and use different coal face, the coal cinders of granular size, fire bars 10 gaps on the fire grate 7 must not＜10mm, less than this limit, then be unfavorable for falling ash and ventilation, the coal reef is remaining, cumulative above can making fire bars 10 like this, has a strong impact on coal burning.Fire grate 7 and fire bars 10 and cross section can be triangular form, ladder type, camber etc.

Consult Fig. 6, shown in Figure 7, have small through hole, bell 11 to cover on stone or metal plate for standing a stove on as a precaution against fire 4 in the middle of the bell 11, stone or metal plate for standing a stove on as a precaution against fire 4 can be that round (as Fig. 4) also can be square (as Fig. 7).
