Abstract

The utility model provides a combustion apparatus for Chinese meal gas cooker and is a dual vortex blast burner. The structure of the utility model is equipped with an outer shell, a pipe, a gas-jet and a cyclone louver. The gas-jet is a looping type and can flexibly change the relevant jet head based on different air sources. The snorting adjustable valve equipped on the air pipe can make the blower operate under the normal condition. The burner implement has the advantages of stable combustion, high flame temperature, good commonality, adjustable design load, convenient installation and maintenance, easy producing, low cost, etc. The utility model can extend for the application on hotel and restaurant, and is provided with the important meaning of energy conservation and environmental protection.

Description

Dual vortex blast burner
The utility model provides a kind of auxiliary combustion equipment of Chinese meal gas range, belongs to the gas works technical field.
The Chinese meal gas range is that a kind of flame is concentrated, ignition temperature is high, adaptable kitchen range.Along with developing rapidly of urban coal gasification, the more and more of Chinese meal gas range are used in hotel, restaurant.But people have found the Chinese meal gas range auxiliary combustion equipment of present use by practice, or are called burner for gas cooker and exist following problem, and the above-mentioned advantage of Chinese meal gas range can not be found full expression.For example: 1, the blowing-type gas range that uses at present, air and coal gas directly mix, and are difficult to guarantee to mix, and cause flame instability, and combustion efficiency is bad; 2, volume is bigger, and gas-jet can not change, if when source of the gas changes, whole burner all will change, so lack versatility; 3, adopt the size of valve control air quantity, when the less air quantity of needs, close minor valve, make blower export pressure raise, blower fan is worked under abnormal condition, very easily damages, simultaneously, because blast raises, cause the fluctuation of air discharge velocity big, the stability of influence burning.Thereby some blowing type gas kitchen range is not then simply established adjusting valve, though consequently the life-span of air blast has prolonged, but flame instability, when the coal gas amount was turned down, excess air was big, the flame temperature and the thermal efficiency are reduced significantly, and air consumption increases, and causes energy waste; 4, burner is not quick detachable, the installation and maintenance inconvenience.
The purpose of this utility model be exactly to make burner reach standard energy-efficient, easy to use with novel design at the shortcoming of existing burner, and the protection air blast is without prejudice.How to realize below in conjunction with accompanying drawing narration above-mentioned purpose.
Fig. 1: bispin stream blast roasting device structure chart
Fig. 2: quirk vertical view
Among the figure: 1-quirk, 2-gas-jet, 3-gas pipe, 4-eddy flow leaf grating, 5-air hose, 6-air control valve, 7-gas regulator, 8-air blast, 9-flange, 10-shell, 11-ring flange, 12-quirk shell
Dual vortex blast burner is by burner housing 10, gas-jet 2, and cyclone louver 4 and air blast 8 and air hose 3, gas pipe 5, control valve 6,7 forms. The top of burner housing 10 is the quirks that are the rounding bench-type, the bottom is connected with air blast 8 by air hose 5, at air hose 5 air control valve 6 of the usefulness of leaking informaton is installed, gas pipe 3 enters shell 10 by the flange seal connection, inlet end at gas pipe has gas regulator door 7, gas-jet 2 is quills that are buckled in the gas pipe gas outlet, is uniform-distribution with some on the barrel of sleeve and diameter inclined hole at an angle, and coal gas is the eddy flow shape along inclined hole and sprays clockwise. Gas pipe cover between quirk 1 and air hose has the cyclone louver 4 of circular ring type, and blade and plane are 45° angle, is enclosed within on the gas pipe after cyclone louver processes, and installs, changes very convenient.
During the work of bispin stream blast roasting device, coal gas is spiral-flow type along inclined hole and sprays clockwise and rotate and rise from gas-jet, cross the eddy flow leaf grating from the air communication of air hose, is counterclockwise eddy flow and rises.Coal gas and air rotate to intersect and have improved mixing intensity, and the two mixes, and make flame temperature high and stable.If when needing to reduce air output, open the valve that leaks informaton as required and get final product.Reverse by original " pass " to " opening " has fundamentally solved the problem that blower export pressure increases like this, makes it be in normal duty all the time.The gas-jet of loop type, for using different sources of the gas to bring great convenience, because source of the gas is not simultaneously, the quantity of spray orifice, diameter are also different, so every burner is equipped with some gas-jets, when changing source of the gas, only need change corresponding gas-jet, promptly applicable to various sources of the gas, as liquefied petroleum gas, natural gas or coal gas etc.For with a kind of source of the gas, change the shower nozzle in different apertures, can change the design load of burner.
By above narration as can be known, the utility model has possessed following several advantages:
1, coal gas and air mix, the flame temperature height, flameholding;
2, be equipped with the gas-jet that is suitable for various sources of the gas, versatility is good, and the design load is adjustable;
3, whole burner adopts fabricated construction, and be easy to installation and maintenance;
4, adopt the valve regulated air output that leaks informaton, make air blast keep normal duty;
5, the burner structure compactness, volume is little, processing technology is simple, cost is low, is easy to promote.
Embodiment 1, and burner housing is made of thick 6~9 millimeters seamless steel pipe, and top is quirk, and diameter is 1.59 millimeters, the liner refractory mortar, and clay is smeared into the inclined-plane, makes quirk be the rounding bench-type; The middle part diameter is 133 millimeters, and lower diameter is 159 millimeters, in, lower case welds together by annulus, top connects with the middle part by ring flange 11.Gas pipe 3 is fixed on shell 10 bottoms by flange 9.It is that 75 millimeters round steel is made that the gas-jet diameter is 55 millimeters high, and 45 ° of chamferings of round steel upper end car are milled diameter and be the circular hole of 45 millimeters and 38 millimeters in the lower end, and each dark 30 millimeters is 45 ° of inclined holes of circular hole drilled in middle of 38 millimeters at diameter, and the aperture is 1~2 millimeter.The eddy flow leaf grating is to be made by six screw type blades that are welded on two annulus, and blade and annulus angle are 45 °, and blade is made of the steel plate of 3 millimeters thick.
Embodiment 2: the quirk shell of burner, gas-jet, and the eddy flow leaf grating is cast iron, and various sizes are identical with embodiment 1.
