An air inlet is equipped on the motherboard of the housing, the gas enter into the pre-heater from the gas intake pipe to execute pre-warming during operation, and then enters into the spacer ring from the breach point of the cylinder type spacer ring, and spurts out from the air nozzle on the head plate of the pre-heater, which can heat the pan body after ignition. The gas combustion burner is applied in offices, schools, hotels, and restaurants for cooking.

Description

A kind of single head energy-saving gas burner

[technical field]

The utility model relates to a kind of gas burner, is a kind of single head energy-saving gas burner that is used for office, school, enterprise, restaurant large stove specifically.

[background technology]

At present, each office, school, enterprise or restaurant adopt clean, sanitary gas burner to cook mostly, cooking, but this gas burner in the past can only be used for high pressure or pressurized air source, can not be used for low-pressure gas source, otherwise just can not burn or firepower too little, can not satisfy large stove and cook, the needs of cooking, and the price of low-pressure gas source such as natural gas and alcohol is lower than the high-pressure air source, and source of the gas is wide, helps reducing production costs energy savings.At present, though this class burner can satisfy large stove user's needs, find that from practice its energy-saving effect is also not very good, afterheat utilization also has the potential to be tapped.Users also wish existing burner is further improved, and with further energy-saving and cost-reducing, save cost.

[summary of the invention]

For further improving the above-mentioned defective of existing gas burner, the utility model provides a kind of single head energy-saving gas burner, further to utilize waste heat, improves energy-saving effect, reduces use cost.

For solving its technical problem, the technical solution adopted in the utility model is: this burner includes housing, fire-resistant circle, igniter and gas inlet pipe, its feature is: 1. be provided with uncovered combustion chamber in housing, be provided with fire-resistant circle and igniter around the combustion chamber top, the body wall at combustion chamber middle part is provided with a plurality of air vents, the bottom of combustion chamber is provided with gas preheater, and the top board center of preheater is provided with air nozzle, and the base plate of preheater is provided with gas inlet pipe; 2. be provided with notched column type combustion gas shading ring between top board in preheater and the base plate, isolate the division board that is provided with between ring wall and the preheater shell from the base plate to the top board in the other column type combustion gas of gas inlet pipe mouth, this division board is between gas inlet pipe mouth and column type combustion gas shading ring breach.Directly enter column type combustion gas shading ring in order to block the combustion gas that newly enters from the indentation, there of column type combustion gas shading ring, must allow the combustion gas that newly enters after the cavity preheating between column type combustion gas shading ring and the preheating heat housing, indentation, there from column type combustion gas shading ring enters in the annulus again, air nozzle from column type combustion gas shading ring top ejects ignition in the combustion chamber of combustion chamber middle and upper part at last; 3. be provided with air inlet on the housing base plate, air enters in the housing from this air inlet, and a plurality of through holes from the body wall of combustion chamber middle part to enter the combustion chamber of combustion chamber combustion-supporting.

The utility model is compared with existing similar burner, and following progress is arranged:

1. owing to be provided with gas preheater in the bottom, combustion chamber of combustion chamber, (cold) combustion gas newly must be through the preheater preheating, when temperature being risen to be lower than the temperature of burning-point, enters column type combustion gas shading ring and goes from the nozzle ejection, help the abundant burning of combustion gas, improve the utilization rate of combustion gas;

2. owing to of the present utility modelly can make combustion gas utilize the waste heat of self to heat, so this fuel gas buring makes fully that harmful components obviously reduce in the gas that gives off, and helps reducing the pollution to environment;

3. the utility model is simple in structure, makes easily, and cost is low, and is therefore easy to utilize.

[description of drawings]

Below in conjunction with the drawings and specific embodiments the utility model is further specified.

Fig. 1 is a structural representation cutaway view of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the vertical view when preheater does not have cover plate among Fig. 1.

Among the figure: 1 fire-resistant circle; 2 igniter guard shields; 3 combustion chambers; 4 igniters; 5 housings; 6 gas inlet pipes; 7 air intlets; 8 preheaters; 9 column type combustion gas shading rings; 10 dividing plates; 11 air nozzles.

[specific embodiment]

With reference to accompanying drawing: the combustion chamber 3 that is provided with a column type at the center of column type energy-saving burner housing 5, around the fire door of this combustion chamber, be provided with fire-resistant circle 1, the bottom of fire-resistant circle 1 is provided with igniter guard shield 2, be provided with the igniter 4 that comprises ignition and switch in the igniter guard shield, wherein switch is installed in surface of shell, and fire-resistant circle and igniter device guard shield are arranged on the top of housing 5; On the core wall of the middle part of combustion chamber 3, be provided with a plurality of air vents, so that allow air enter combustion chamber, be provided with preheater 8 in the bottom of combustion chamber 3, the top board of preheater is provided with air nozzle 11, centre in the preheater is provided with column type combustion gas shading ring 9, and the upper end of this shading ring communicates with air nozzle on the top board, and the lower end of shading ring links to each other with the base plate of preheater, have a breach on the sidewall of shading ring, so that allow the combustion gas after being heated enter shading ring; On the base plate of preheater, be provided with gas inlet pipe 6, in order to allow combustion gas enter the preheater preheating by this input pipe, be provided with a division board 10 between gas inlet pipe inlet in preheater and the column type combustion gas shading ring breach, directly enter shading ring in order to the combustion gas that prevents from newly to enter from indentation, there, and go from air nozzle ejection, being provided with air intlet 7 in the bottom of burner shell 5, air enters from this import department, by the through hole on the furnace core wall, it is combustion-supporting to enter the combustion chamber combustion chamber.
