Abstract

The utility model relates to a double-opening secondary air intake furnace for domestic use. The utility model is characterized in that the upper part of the furnace body is equipped with a secondary air intake fire hole 7. The air intake fire hole 7 is sealed by a perforated circular sealing gland 11 out of the furnace body. The inside of the furnace body is equipped with an oxygen-containing ventilation hollow chamber 8 communicated with the air intake fire hole 7, an annular ventilation slot and a dentiform slot 10 on the upper edge of the internal furnace which form a secondary air channel of the utility model. The advantage of utility model is that the coal can burn sufficiently. The flame is heightened, and the heat efficiency is increased. The time of banking fire is prolonged, and the energy source is saved. The residue of the carbon monoxide is greatly reduced, so the phenomenon of carbon monoxide poisoning is avoided.

Description

Double-opening secondary air-intaking furnace

The utility model belongs to the heating stove for civilian use tool.

The former stove implements of existing single port coal is mainly used for people's heating, cooking.The primary structure of known " courser board " single port efficient energy-saving furnace is, an air inlet is arranged at the bottom of body of heater, air inlet adopts garden shape fire sealing cover, and stone or metal plate for standing a stove on as a precaution against fire employing spill is flat and have 10 whirlwind roads, and furnace bottom and flue height increase whole body of heater and increase, this " courser board " single port stove and accessory, owing to strengthened suction draught and be provided with the whirlwind road, flare in the furnace bottom rotation and on, and flare has certain height, make coal fully to burn, prolonged heat time heating time; Because adopt garden shape fire sealing cover, the performance of banking up a fire is good, banking up a fire can keep more than 12 hours and do not go out, and has played energy-conserving action, and therefore " courser board " single port stove and accessory once obtained the trade appraisal second prize of nineteen ninety Shaanxi Province Economic and Trade Commission tissue.

Advance hypoxgia in order to solve the single port stove and accessory owing to what an air inlet caused, coal combustion insufficient, flare is not prosperous, and it is many to produce carbon monoxide when especially warming oneself, easy drawback such as poisoning, the utility model has designed the twoport secondary air intake furnace.The twoport secondary air intake furnace significantly improves 6 test indexs, and coal is fully burned, and flare increases, and the thermal efficiency obtains utilizing.After banking up a fire, because secondary air can be avoided gas poisoning, the comparable original prolongation of fire-sealing time is more than 4 hours.

The realization the technical solution of the utility model is, set up an air inlet 7 on the top of stove and accessory, and air inlet seals with garden shape capping 11 with holes and the existing air inlet 5 in stove and accessory bottom has formed the oxygen supply of twoport air intake secondary.The air inlet 7 of body of heater is upward taper hole shape, as shown in Figure 2.Depression position except that top air inlet and stone or metal plate for standing a stove on as a precaution against fire bottom between stove and accessory outer wall and inner bag is to hold the oxygen ventilation cavity 8, and all the other are loaded with insulation material, as shown in Figure 1, 2.There is annular wind groove 9 on periphery edge at the flue upper wall, and this annular wind groove 9 communicates with the profile of tooth groove pore 10 that holds oxygen ventilation cavity 8 and flue perisporium upper edge.

Advantage of the present utility model is, owing to increased the secondary air mouth and the annular wind groove of upper end, coal is fully burned, and flare increases, and has increased the thermal efficiency, and fire-sealing time prolonged more than 4 hours, had saved the energy.Bank up a fire the back because the oxygen of holding ventilation cavity is arranged, significantly reduced remaining carbon monoxide, avoided gas poisoning.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a front section view of the present utility model;

Fig. 2 is a side sectional view of the present utility model;

Embodiment, as shown in Figure 1, flue 2 is inserted in the body of heater shell 1, fills with insulation material 4 therebetween, and stone or metal plate for standing a stove on as a precaution against fire 3 is fixed in the top of shell 1, they and handle 6 and air inlet 5 formations main body of the present utility model.As shown in Figure 2, the shape of body of heater air inlet 7 is tilted conical holes upwards, and it communicates with the depression position that stone or metal plate for standing a stove on as a precaution against fire 3 bottoms form, and forms and holds oxygen ventilation cavity 8, and air inlet 7 seals in body of heater external application garden shape capping 11 with holes.There is a circle profile of tooth groove 10 the perisporium upper edge of flue 2, in profile of tooth groove outer and stone or metal plate for standing a stove on as a precaution against fire 3 bottoms be provided with annular wind groove 9.Serrate slot 10 and annular wind groove 9 and hold oxygen ventilation cavity 8 and air inlet 7 communicates.

Claims

1, a kind of by body of heater shell 1, flue 2, stone or metal plate for standing a stove on as a precaution against fire 3, the civilian twoport secondary air intake furnace that handle 6 and following end closure 5 constitute, between flue and body of heater shell, be filled with insulation material 4, it is characterized in that, set up an air inlet 7 on the top of stove and accessory, air inlet 7 is upward bellmouths, between the stove and accessory shell 1 of stone or metal plate for standing a stove on as a precaution against fire 3 bottoms and flue 2 is to hold oxygen ventilation cavity 8, one circle profile of tooth groove 10 is arranged in flue 2 perisporium upper edges, space in profile of tooth groove outer and stone or metal plate for standing a stove on as a precaution against fire 3 bottoms forms annular wind groove 9, profile of tooth groove 10 and annular wind groove 9 and hold oxygen ventilation cavity 8 and air inlet 7 communicates successively.
