Description

Stove mouth with cylindrical hearth

The utility model belongs to the stove and accessory applied technical field.

Traditional coal gas or natural gas converter nose are cylinder iron cast and are formed, comparatively heavy, also very easily get rusty, manufacturing process is also comparatively complicated simultaneously, usually through molding, fills out the husky heart, casting die, filling molten iron, scabble stove heart face and boiler tube, these complex procedures effort of taking a lot of work with lathe again after the moulding, it is many that product takes product, and efficient is low.The converter nose made from this casting method easily gets rusty in use.Especially the shallow soup slag that falls very easily corrodes fire hole inner edge sidewall when cooking.Cause oxidation rust to increase gradually and clog fire hole, coal gas can't evenly be burnt maybe can not finish burning and flow in the atmosphere and cause danger.Cast coarse converter nose inwall simultaneously, can produce stream and influence coal gas and Air mixing ratio, also reduce the flowing velocity of coal gas simultaneously, flowing velocity is slow excessively, makes that the impulsive force that produces between gas molecule is not enough, coal gas can not fully mix with air and then influence fully and burn.

For this reason the inventor of tw Taiwan to design this structure converter nose seat of a kind of " novel converter nose " " with stainless steel metal bending forming and constitute a plate-like stove heart and stove heart portion by two concentric circles have the plate-like converter nose of oblique angle and become the coal gas path at the converter nose seat along stretching a hollow form catheter-shaped " be coal gas and Air mixing district, coal gas is directly gone up kindling heart portion diffusion combustion again with after air mixes.In fact this structure still is a traditional structure, and be divided into stove heart portion and following converter nose seat again at furnace head, by converter nose seat mixing air and coal gas, this structure is the same with traditional structure, after coal gas enters the converter nose seat from conduit, part coal gas directly rushes to stove heart portion and discharges, and does not reach fully to mix with air and burn.

In addition, traditional furance stack body bottom and top be with wide, coal gas and Air mixing body skewness in furance stack body, and combustion gas can not be expanded whole furance stack body and be caused and give vent to anger manyly near the round of breather pipe, away from giving vent to anger less of round, and influences the efficiency of combustion of converter nose.

Therefore, the purpose of this utility model is, designs a kind of converter nose with round tripe bodily form, has at a high speed evenly mixing air and coal gas or natural gas, the effect of completing combustion in converter nose, also have simultaneously antirust, in light weight, be easy to make with the advantage of cleaning.

The utility model adopts the waist of furance stack body to be circle tripe shape, and connects mozzle at its side dolly, and furance stack body is the ring-type furance stack body, and there is small furnace at its center.Small furnace is positioned on the support plate, and the small furnace lower end is provided with mozzle, and the mozzle end is the horn-like air-condition plate that is coupling, and the top, porch of mozzle is provided with deflector.The said structure design has realized the purpose of this utility model.

The utility model becomes waist to have the furance stack body of round tripe shape with antirust plate stamping, mozzle and boiler tube, coal gas or natural gas are not obstructed at above-mentioned level and smooth inner face, air and combustion gas are fully mixed, mist fully expands the abundant burning that whole furance stack body is beneficial to combustion gas with combustion gas after the furance stack body inner concave arc surface spirals.Simultaneously the stove spare made from antirust sheet material also have antirust, in light weight, corrosion-resistant, be easy to make, long service life, easy cleaned advantage.

Below in conjunction with Figure of description and embodiment structure of the present utility model is further described.

Fig. 1 is the utility model schematic diagram.

Fig. 2 cuts open schematic diagram for the utility model side.

Fig. 3 is the utility model stove interior portion structural representation.

Making furance stack body 1, stove heart lid 2 of top imbrication, furance stack body 1 and stove heart lid with antirust plate stamping moulding is the ring-type build, and stove heart lid 2 is divided into round 21.To be monomer one deck structure be designed to circle tripe shape in waist to furance stack body, lining portion is that cancave cambered surface can give gas or natural gas the spirals portion in the furance stack body that is uniformly distributed in.Furance stack body side circle tripe shape dolly connects mozzle 3, a mozzle and is also made by rush-resisting material.The mozzle lower port flushes boiler tube 4 and still makes with rush-resisting material.The end of boiler tube 4 is horn mouth and is coupling an air-condition plate 5 in order to regulate the amount that air enters furance stack body.

Be provided with small furnace 1B at the center of ring-type furance stack body 1, which is provided with port heart lid 2B is the little fire of the stove heart, be beneficial to the use of cooking of little fire, small furnace is still used stainless board making, its bottom connects boiler tube 4B through mozzle 3B, the holding function of small furnace is identical with aforesaid furance stack body 1 holding function, so only furance stack body 1 is described further.Coal gas or natural gas G are by the centre bore 51 of boiler tube 4 ends through air-condition plate 5, the spirt straight line enters in the smooth and smooth boiler tube of the inner edge that forms with the sheet material punching out, coal gas is not obstructed and is able to flow at high speed under the pressure of gaspipe line own, because the gas speed height of distance around here, porch air-condition plate 5 set air hand-holes thereby produce siphon principle and air A is brought in the boiler tube then, because of boiler tube 4 and mozzle 3 and furance stack body 1 all form with plate stamping, and smooth coal gas no choked flow and flow at high speed in boiler tube mixes mutually with the inhaled air of being with in each component table, flow to furance stack body 1 through mozzle 3, above the porch of mozzle 3, be provided with a deflector 11, can evenly riddle the guiding of the combustion gas in the entering furance stack body in it, cover 2 set round 21 current drainages at the stove heart that is covered from it and do fully burning.Obviously, smooth inner face can give gas and mix, makes airborne oxygen molecule to surround the coal gas gas molecule with high velocity flow and then with highdensity air in each component table, causes coal gas fully to burn.

(as shown in Figure 3) when coal gas in boiler tube 4 with after air fully mixes, when mozzle 3 vertically enters furance stack body 1, at first the set deflector 11 of portion in it is hit in spray, deflector two limits steeve with suitable angle and with gas diversion to whole furance stack body, on average and fully discharge along the set round 21 of stove heart lid and burn.Be cancave cambered surface in circle tripe shape furance stack body inside, deflector is positioned near this cancave cambered surface, and combustion gas can evenly disperse the gas in the round along this cancave cambered surface under the effect of deflector, be beneficial to full combustion of gas.

In the set small furnace B in furance stack body 1 center, deflector is also arranged, it is mozzle 3B down, its structure is identical with aforementioned furance stack body structure, small furnace is positioned on the support plate 24, support plate is fixed in the bottom of furance stack body 1, and support plate the place ahead is stretched and established a buckle 22 and can detain and ride on the stove beam 23 in order to fixedly furance stack body and small furnace.When needing little fire to cook, only open towards the gaspipe line of conduit 4B and get final product.

Because the utility model is a raw material with stainless sheet material, it is antirust, in light weight that it is had, and is easy to the advantage of making and cleaning.In a word, simple in structure, the long service life of the utility model, combustion efficiency is good, is a kind of comparatively desirable combustion gas converter nose.
