Description
Technical field
The invention belongs to Gas appliance technical field, it is related to a kind of turbulent burner, it is especially a kind of for gas-cooker
Turbulent burner.
Background technology
Gas-cooker refers to carrying out for kitchen use of straight fire heating with gaseous fuels such as liquefied petroleum gas, artificial coal gas, natural gases
Tool.Gas-cooker is mainly made of devices such as burner, igniter, grate, air inlet pipe, valve bodies,
Burner includes the structures such as burner, interior outer fire cover, and when work, combustion gas enters from air inlet pipe in stove, by gas valve
Adjusting enter in burner, while mixing portion of air (this partial air is referred to as primary air), these mixed gas from
It is sprayed in the fire hole of fire cover while being ignited device and light to form flame (required air is referred to as auxiliary air when burning),
And then for heating the cooker being placed on grate.
Existing gas-cooker is mostly arranged an air inlet (air inlet pipe) and enters burner for combustion gas, and combustion gas is in stove in the short time
Head internal circulation is unsmooth, is easy to cause fuel gas buring and is not enough；In addition, burner internal structure is often set as single chamber
Body is unfavorable for the abundant circulation of combustion gas, and combustion efficiency is poor and safety is relatively low.
And the material of gas-cooker is general steel alloy, aluminium alloy or copper alloy in the prior art, not only intensity is general, and
Temperature tolerance, corrosion resistance are also poor, affect the service life of gas-cooker.
In conclusion to solve the deficiency being currently used on the burner structure of gas-cooker, need to design a kind of design conjunction
The good turbulent burner of reason, combustion efficiency.
Invention content
The purpose of the present invention is there is the above problem in view of the prior art, it is proposed that a kind of reasonable design, combustion efficiency
Good turbulent burner.
Object of the invention can be realized by the following technical scheme：A kind of turbulent burner, including：
Outer burner, in circular setting, fastened on outer burner have outer fire cover and outer fire cover surrounded with outer burner to be formed it is outer
Mixing chamber；
Interior burner is plugged in the middle part of outer burner, and fastening has inner fire cover on interior burner and inner fire cover surrounds shape with interior burner
At inner mixing chamber, interior burner bottom offers the through-hole with inner mixing chamber unicom, is provided with and outer mixing chamber unicom around through-hole
Several curved channels；
Conduit assembly, be located at outer burner below, be provided on conduit assembly secondary air inlet pipe corresponding with through-hole and with
Each curved channel several main air inlet pipes correspondingly；
The point column of flame, is set as multiple, and each to put the column of flame with conduit assembly unicom, the described column of flame extend simultaneously straight up
It is arranged close to interior burner outer peripheral sidewall；
Pillar is set as multiple, and each pillar is vertically installed at below conduit assembly；
And the outer burner, interior burner are made of magnesium alloy, the component and mass percent of the magnesium alloy
For：Zn：1.05%-1.80%, Mn：0.35%-0.65%, B：0.15%-0.25%, Zr：0.15%-0.28%, Ce：
0.05%-0.12%, surplus are Mg and inevitable impurity.
In magnesium alloy used in turbulent burner China and foreign countries of the present invention burner, interior burner added with suitable Zn, Mn, B, Zr,
Ce significantly improves the mechanics of magnesium alloy turbulent burner by the synergistic effect of reasonable disposition and generation between each element
Performance and mechanical performance especially significantly improve the intensity of turbulent burner, heat resistance, corrosion-resistant, and then extend swirl flow combustion
The service life of device.
Suitable zirconium is added in magnesium alloy of the present invention, can reduce ardent tendency with crystal grain thinning, improve mechanical property.
Because the chemical activity of zirconium is high, compound between refractory metal is easily formed with other elements such as aluminium, silicon, iron, tin and manganese element,
And lose the crystal grain thinning of zirconium or so, therefore, reduce the content of above-mentioned element in magnesium alloy of the present invention to the greatest extent.Zirconium crystal grain thinning
Reason is that the solubility with temperature of the zirconium in liquid magnesium is reduced and reduced, and in process of setting, zirconium is first with α-Zr crystallization analysis
Go out, lattice structure is similar to magnesium, plays non-spontaneous forming core so as to crystal grain thinning.In addition, zirconium can also improve magnesium conjunction
The fusing point of gold, to be effectively improved the temperature tolerance and corrosion resistance of turbulent burner.
In the magnesium alloy, due to formation condition difference, the existence form of iron phase in the alloy may be simple substance, solid solution or
Person's intermetallic compound.Since the equilibrium potential and stable potential of magnesium are all very negative, and the hydrogen-evolution overpotential of iron is relatively low, then iron phase
In the presence of the corrosion resistance that can seriously affect turbulent burner；Meanwhile the presence of iron phase can seriously damage the tissue and power of magnesium alloy
Performance is learned, its reduction of pliability, brittleness is caused to increase.Although because containing Zr in turbulent burner magnesium alloy of the present invention, should keep away
Exempt from the presence of the elements such as aluminium, silicon, iron, tin and manganese, but in order to effectively inhibit the adverse effect of iron phase, turbulent burner magnesium of the present invention
1.05%-1.80%Zn, 0.35%-0.65%Mn and 0.15%-0.25%B are added in alloy.Zn can reduce Fe, Ni,
Influence of the objectionable impurities such as Cu for alloy corrosion resistance energy, but the addition of Zn needs stringent control, if Zn too high levels
The hot cracking tendency of alloy is will increase, and influences the effect of Zr.Mn and B is mutual with impurity F e in magnesium liquid collectively as iron removing reagent
Effect forms the precipitations such as the intermetallic compound such as MnFe, FeB that solubility is minimum, fusing point is high and density is big, reaches removing impurity
The purpose of Fe.
0.05%-0.12% rare earth element ces have been additionally added in magnesium alloy used in the outer burner of the present invention, interior burner, Ce's
Atomic radius is 0.183mm, and electronegativity 1.12, within 15%, electricity is negative for the atomic radius of Ce and the relative difference of magnesium atom
Property difference be respectively less than 0.4, therefore could be formed with the solid solution of limit and the compound of stabilization, to preferably realize they
Effect in magnesium alloy.Ce has good solution strengthening effect in the magnesium alloy, can effectively prevent magnesium alloy crystal grain under high temperature
The sliding grown up with crystal boundary,
Outside the present invention in burner, the magnesium alloy used in interior burner, it is added suitable Zn, Mn, B, Zr, Ce, and into one
The content of step limitation impurity element S i, Fe, Ni, Cu significantly improve eddy flow combustion by their reasonable disposition and synergistic effect
The heat resistance of burner, corrosion resistance.
Preferably, Zn：1.1%-1.25%, Mn：0.45%-0.55%, B：0.16%-0.22%, Zr：0.16%-
0.22%, Ce：0.08%-0.10%, surplus are Mg and inevitable impurity.
The impurity includes Si≤0.002%, Fe≤0.002%, Ni≤0.002%, Cu≤0.002%.
In a kind of above-mentioned turbulent burner, outer burner, interior burner can be made by following processing method：
S1, melting pre-treatment：By the component and its mass percent prepared furnace charge of above-mentioned magnesium alloy, by charge preheating
It is spare after to 150-180 DEG C, then crucible is preheated at 500-580 DEG C spare after kermesinus；
