Description

Liquid fuel atomizing burner

The utility model relates to a kind of liquid fuel evaporation kitchen range, belongs to kitchen range.Be particularly useful for pentane is the vaporization kitchen range of the liquid fuel of main content.Its formation comprises receiver, valve, pressure reducing regulator, damper regulator, economizer bank, burner, igniter, preheating switch, air escape cock, connecting line.

For making full combustion of fuel, liquid fuel needs through vaporization.Multiple gasification method is arranged, and in the prior art, liquid fuel is made its preheating vaporization in the way of burner of flowing through be the gasification method that generally uses.Cause in the atomizing of combustion preheater or the source of vaporized fuel various channels are arranged, Chinese patent application number is that 90207754.6 patent application discloses and a kind ofly need not add other fuel, do not acquire in addition under the equipment, makes fuel make the liquid fuel evaporation kitchen range of its preheating vaporization in the burner way of flowing through.After entering the kitchen range body from the liquid fuel of receiver, continue to run through and mistake from burner along pipeline, divide two-way then, wherein one road pipeline leads to preheating switch.When opening this switch, liquid fuel is derived, and overflowing is put in the pallet of burner bottom, is used for igniting; Another road pipeline penetrates burner, passes after the coiling therein, then through air escape cock, enters burner combustion.Like this, the liquid fuel after passing the preliminary heating of burner is got back and is heated once more, thereby vaporization, goes into burner combustion through air escape cock then.But, the liquid fuel evaporation kitchen range of prior art from preheating switch overflow atomizing or the fuel of having vaporized very limited, igniting is difficult for, preheating is ineffective, the thermal efficiency of fuel combustion is not high, be the liquid fuel of main content for pentane especially, shortcoming is more obvious; The preheating switch and the air escape cock of prior art are provided with respectively, and operation is very much inconvenience; The pipeline complexity is the another weak point of prior art.

The utility model is intended to overcome the deficiencies in the prior art and a kind of liquid fuel evaporation kitchen range of designing, and being particularly useful for pentane is the liquid fuel evaporation kitchen range of main content.

The purpose of this utility model can reach by following technical proposals: burner design is become main chamber and subsidiary combustion chamber, corresponding configuration primary air mixing chamber and secondary air mixing chamber.Main chamber is a circulus, and subsidiary combustion chamber is positioned at the central authorities of ring, and its end face is provided with the infrared ray plate of mesh-like structure, and economizer bank props up above subsidiary combustion chamber and infrared ray plate, passes from the main chamber of ring-type.Preheating switch and air escape cock are designed to one, constitute a kind of plug valve, utilize spool to place different orientation, make respectively that main chamber is closed, subsidiary combustion chamber is opened; All open major and minor combustion chamber, finishes the operation of combustion preheater and normal combustion.

Design of the present utility model makes that igniting is easy, quick combustion, in the whole process of burning, there is special thermal source to make liquid fuel obtain abundant preheating vaporization all the time, thereby the thermal efficiency height of burning, flame stabilization, especially be the liquid fuel evaporation kitchen range of main content for pentane, such design is necessary especially; Pipeline is simple and direct, easy and simple to handle to be another advantage of the present utility model.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structural representation of liquid fuel evaporation kitchen range;

Fig. 2 is the burner vertical view;

Fig. 3 is the burner profile;

Fig. 4 is the plug valve valve seat;

Fig. 5 is the plug valve spool.

Below in conjunction with embodiment the utility model is done further statement:

See Fig. 1, Fig. 2 and Fig. 3.Burner comprises main chamber (3), subsidiary combustion chamber (2), primary air mixing chamber (8), secondary air mixing chamber (9).Burner can cylinder iron wait the metal material cast solid.Main chamber (3) is a circulus, and subsidiary combustion chamber (2) is positioned at main chamber (3) central authorities by following, and infrared ray plate (10) is loaded on subsidiary combustion chamber (2) top.The economizer bank (1) that is connected with receiver, angle valve, pressure-reducing valve passes in the middle of subsidiary combustion chamber (2) and infrared ray plate (10) top, main chamber (3) top, is connected with plug valve (4), (5) then.

Figure (4) is plug valve valve seat (4).The hole I is a fuel inlet, is communicated with economizer bank (1); The hole II is chewed (6) and is connected with main jet; The hole III is connected with secondary nozzle (7).Major and minor nozzle (6), (7) are connected with major and minor air mixing chamber (8), (9) respectively; Major and minor air mixing chamber (8), (9) are connected with major and minor combustion chamber (3), (2) respectively.

Figure (5) is plug valve spool (5).Be drilled with 3 holes on it: axial center hole c and radial hole a, b.Hole a, b are positioned at the same side of same axial cross section, and are communicated with hole c respectively.A groove is opened along garden Zhou Fangxiang in the aperture of hole a, and this groove circumferential cross-section is the arcuate slots that arc length accounts for garden girth 1/4.

The igniting knob is installed in the afterbody of plug valve spool (5), and the ignitor of time-delay electronic impulse ignition apparatus is installed in infrared ray plate (10) top.Take the knob that is connected with plug valve spool (5) off, the time-delay electronic impulse ignition apparatus is connected, and ignitor produces spark, and then with plug valve spool (5) half-twist, subsidiary combustion chamber (2) burning as " low baking temperature shelves ", is used for heating economizer bank (1).Also can use when needing the low baking temperature cooking " low baking temperature shelves ", at this moment, hole I on the valve seat (4) is communicated with by its arcuate slots with hole a on the spool (5), hole II and hole b are obstructed, and fuel enters secondary nozzle (7) from economizer bank (1) through plug valve (4), the hole I of (5), groove, a, c, III.Through secondary air mixing chamber (9), to subsidiary combustion chamber (2), the spark burning is met in further atomizing behind infrared ray plate (10) then, makes the liquid fuel of the economizer bank of flowing through (1) obtain sufficient preheating vaporization.

When desiring normal combustion, plug valve spool (5) changes 90 ° again, at this moment, the hole I of valve seat (4), II are communicated with hole a, the b of spool (5) respectively, and fuel enters major and minor nozzle (6), (7) respectively from hole I, a, b, c, II and hole I, a, c, the III of economizer bank (1) through plug valve (4), (5).Subsidiary combustion chamber (2) burns away, and makes the liquid fuel from receiver continue vaporization; Simultaneously, the fuel after vaporization is chewed (6) ejection through main jet, passes through primary air mixing chamber (8) again, to main chamber (3) burning.Because preheating vaporization and normal combustion are carried out simultaneously, thereby main chamber (3) burnt is the fuel of fully having vaporized, the combustion thermal efficiency height, and flame stabilization, free from environmental pollution.

Filter is equipped with in porch in major and minor nozzle (6), (7).Filter rolls with Web materials, and present embodiment rolls into tubular by 120 order brass screens, fills in the porch of nozzle (6), (7), is turned back in the outer end then, makes it axially not straight-through.Filter easy accessibility of the present utility model is easy to cleaning, can stop not only that impurity enters nozzle and causes obstruction in the fuel, and can play throttling action, makes burned flame more stable.
