Abstract

The utility model relates to a pressure blowing gas stove for stir-frying. The main body of the burner of the pressure blowing gas stove for stir-frying is composed of a base chamber, a combustion chamber, a fire-inversion ring and a flame nozzle. A gas nozzle is hermetically connected to an intake tube port which is in the flame nozzle, gas jetting holes are distributed on the surface of the gas nozzle, a gap is arranged between the gas nozzle and the flame nozzle, and the bottom of the combustion chamber is provided with a fresh air inlet bore which communicates the base chamber with the gap. Gas and blast can enter into the gap between the flame nozzle and gas nozzle, and obtain premixing and complete combustion in the gap. The utility model has the advantages of gas saving, and low noise. The serious overproof problems of carbon monoxide gases can be solved.

Description

The pressure air blowing gas is fried stove

The utility model relates to a kind of gas furnace, and particularly a kind of pressure air blowing gas is fried stove.

At present, the stir-fry stove that used by hotels and restaurants by uses is a fuel with liquefied petroleum gas or piped gas, and it is combustion-supporting to be equipped with the fan with low voltage air blast often in burning.Popular a kind of Guangdong formula is fried stove recently, drum pressure blower fan in the use, and firepower is powerful.Its composition comprises burner body, fuel gas source, air inlet pipe and control valve thereof, air blast, blast pipe and control valve thereof, burner body is made up of base cavity, combustion chamber, anti-pyrosphere and bocca, air inlet pipe is communicated with the combustion chamber bottom, the bocca of surface distributed fire jetting hole covers in air inlet mouth of pipe top and is tightly connected with the combustion chamber bottom, blast pipe is communicated with base cavity, has the fresh air inlet that is communicated with base cavity on the combustion chamber sidewall.The shortcoming of its existence mainly is that air intake does not just directly enter combustion chamber with the air inlet premixed, and under the situation of pressure air blast, it is insufficient to burn, and CO gas seriously surpasses the national environmental protection index, infringement staff physical and mental health.Because blower power is too big, and the noise of burning is deafening, also seriously surpass the national environmental protection index simultaneously.

The purpose of this utility model is, overcomes above-mentioned pressure air blowing gas and fries the shortcoming that the stove burning is insufficient, noise is big, provides a kind of sufficient combustion, pressure air blowing gas that noise is low to fry stove.

The purpose of this utility model is achieved through the following technical solutions: a kind of pressure air blowing gas is fried stove, its composition comprises burner body, fuel gas source, air inlet pipe and control valve thereof, air blast, blast pipe and control valve thereof, burner body is by base cavity, combustion chamber, anti-pyrosphere and bocca are formed, air inlet pipe is communicated with the combustion chamber bottom, the bocca of surface distributed fire jetting hole covers in air inlet mouth of pipe top and is tightly connected with the combustion chamber bottom, blast pipe is communicated with base cavity, has the fresh air inlet that is communicated with base cavity on the combustion chamber sidewall, it is characterized in that the air nozzle that is tightly connected on the air inlet mouth of pipe in bocca, air nozzle surface distributed fumarole, have the gap between air nozzle and the bocca, the combustion chamber bottom has the fresh air inlet that is communicated with base cavity and this gap.

According to technique scheme, combustion gas and air blast can both enter the gap between bocca and the air nozzle, and obtain premixed in the crack during this time, fire jetting hole by the bocca surface distributed sprays then, fully burning not only solves the problem of CO gas severe overweight, and can save the combustion gas more than 1/3rd in combustion chamber, simultaneously can reduce the power of air blast nearly 1/2nd, thereby noise is also reduced thereupon greatly.

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.

Fig. 1 is the utility model overall structure schematic diagram.

As shown in Figure 1, the composition that the utility model pressure air blowing gas is fried stove comprises burner body 1, fuel gas source 6, air inlet pipe 3 and control valve 2 thereof, air blast 7, blast pipe 9 and control valve 10 thereof, burner body 1 is by anti-pyrosphere 11, combustion chamber 12, bocca 13 and base cavity 14 are formed, air inlet pipe 3 is communicated with combustion chamber 12 bottoms, the bocca 13 of surface distributed fire jetting hole 131 covers in air inlet pipe 3 mouths of pipe tops and is tightly connected with the bottom of combustion chamber 12, blast pipe 9 is communicated with base cavity 14, has the fresh air inlet 141 that is communicated with base cavity 14 on the sidewall of combustion chamber 12, air nozzle 15 is tightly connected on air inlet pipe 3 mouths of pipe in bocca 13, air nozzle 15 surface distributed fumaroles 151, have gap 143 between air nozzle 15 and the bocca 13, the bottom of combustion chamber 12 has the fresh air inlet 142 that is communicated with base cavity 14 and this gap 143.

Among the embodiment, for the mixing ratio that makes air intake and air inlet reaches best requirement, further feature is the automatic pressure regulator 5 of mounting strap control end 51 on the air inlet pipe 3 between fuel gas source 6 and the air inlet pipe control valve 2, air-valve 8 is installed on the blast pipe 9 between air blast 7 and the blast pipe control valve 10, and the control end 51 of automatic pressure regulator 5 is communicated with blast pipe 9 between air-valve 8 and the blast pipe control valve 10 by tube connector 4.So just can air intake pressure be passed to the control end 51 of automatic pressure regulator 5 by tube connector 4, the flow of combustion gas is sent in control by automatic pressure regulator 5, make the ratio of interior combustion gas of burner and air reach required optimum state, it is more abundant to burn, and noise further reduces.
