Abstract
The utility model discloses an air blast burner, which comprises a nozzle, wherein the nozzle is equipped with an air inlet, a gas inlet and an air outlet, the air outlet of the nozzle is communicated with an injection pipe, the air outlet of the nozzle is fixedly connected with the injection pipe through an end cap, the end cap is equipped with an air inlet hole, and the bore of the nozzle is tapered at the inlet portion and flared at the outlet portion. Accordingly, the larger the air quantity is, the larger the air speed is, then the larger the caused negative pressure is, and the larger the sucked gas quantity and air quantity are. Simultaneously, the bore of the injection pipe is tapered at the inlet portion and flared at the outlet portion, the larger the air injected by the nozzle is, the larger the air speed is, and the larger the sucked air quantity is, thereby the mixed gas can be sufficiently mixed with the air for the second time before burning, and then the mixing ratio of air and gas can be automatically controlled by regulating the quantity of air to obtain desired pre-mixing gas. In addition, the flame kernel temperature of the air blast burner is higher than that of common gas stoves, the air blast burner has high combustion heat, enables combustion to be more sufficient, and has high utility ratio.
Description
Technical field
The present invention relates to a kind of culinary burning kitchen range, relate in particular to the culinary forced-air blast burner in a kind of restaurant.
Background technology
Existing hotel, the large-scale cabinet type cooking stove in restaurant all adopt a large-scale basin die cavity chamber usually, and combustion gas is fed in this chamber by aperture or narrow and small slit, again by the air blast air blast, carry out combustion gas and Air mixing.Flame accumulates in this basin die cavity Indoor Combustion, and a large amount of heat energy all accumulate in this basin die cavity chamber, and are little with the utilization rate of heated body transmission of heat by contact, and volume is bigger, and the radiation loss amount is big.And because the baking of a large amount of heats, also relatively more serious to the environmental pollution that the kitchen is sultry, the cook works under this environment for a long time, and its body and mind is all seriously influenced.
Summary of the invention
The purpose of this utility model is to provide a kind of combustion efficiency good, the blast roasting device that heat utilization ratio is high.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of blast roasting device, comprise nozzle, have air inlet, fuel gas inlet and gas outlet on the nozzle, the gas outlet of nozzle communicates with playpipe, fixedly connected by end cap between the gas outlet of nozzle and the playpipe, and end cap is provided with the air inlet hole.
The endoporus of nozzle is convergent shape at inducer, is gradually expanded form at outlet section.
The endoporus of playpipe is convergent shape at inducer, is gradually expanded form at outlet section.
Described fuel gas inlet is arranged on the throat place between inducer and outlet section of nozzle, and in the fuel gas inlet of nozzle Gas Pipe is installed, and Gas Pipe is provided with gas jet orifice.
Described nozzle has external screw thread, and end cap has internal thread, and nozzle is threaded with end cap.
Described end cap has internal thread, and playpipe has external screw thread, and end cap is threaded with playpipe.
Described playpipe outlet section is a bend pipe.
After adopting said structure, owing to have end cap to be fixedly connected between the gas outlet of nozzle and the playpipe, and end cap is provided with air intlet; The endoporus of nozzle is convergent shape at inducer, be gradually expanded form at outlet section, air capacity is big more, wind speed is big more, the negative pressure that is caused is big more, the gas quantity that sucks is also just bigger, the endoporus of same playpipe is convergent shape at inducer, be gradually expanded form at outlet section, the mist that sprays when nozzle is many more, and wind speed is big more, amount of air drawn is many more, make that like this mist can fully carry out mixing with the second time of air before burning, the big I of regulating air capacity is like this controlled the mixed proportion of air and combustion gas automatically, reaches desirable premixed gas, its flame kernel temperature is than the flame of centre temperature height of general gas-cooker, calory burning is big, makes that burning can be more abundant, and the utilization rate of heat is higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
As shown in Figure 1, a kind of blast roasting device, comprise nozzle 1, have air inlet 1-1, fuel gas inlet 1-2 and gas outlet 1-3 on the nozzle 1, the gas outlet 1-3 of nozzle 1 communicates with playpipe 4, fixedly connected by end cap 2 between the gas outlet 1-3 of nozzle 1 and the playpipe 4, and end cap 2 is provided with air inlet hole 2-1.
As shown in Figure 1, in order better to carry out mixing between the air and combustion gas for the second time, the endoporus of nozzle 1 is convergent shape at inducer 1-1-1, and 1-1-2 is gradually expanded form at outlet section; The endoporus of playpipe 4 is convergent shape at inducer 4-1, and 4-2 is gradually expanded form at outlet section.
As shown in Figure 1, described fuel gas inlet 1-2 is arranged on the throat place between inducer 1-1-1 and outlet section 1-1-2 of nozzle 1, and Gas Pipe 3 is installed in the fuel gas inlet 1-2 of nozzle 1, Gas Pipe 3 is provided with gas jet orifice 3-1, can make the size that to regulate intake when combustion gas mixes with air according to air blast like this, automatically regulate the proportioning of mist, make combustion gas to be fully burned.
As shown in Figure 1, in order better to strengthen fixedly connected between nozzle 1 and the playpipe 4, described nozzle 1 has external screw thread, and end cap 2 has internal thread, and nozzle 1 is threaded with end cap 2; Described end cap 2 has internal thread, and playpipe 4 has external screw thread, and end cap 2 is threaded with playpipe 4.
