Description

Multi-purpose flamer of liquified petroleum gas

The utility model is a kind of hand-held blowtorch, obtains to concentrate the thermal-flame that sprays by scoria oil liquify device (propane), belongs to gas combustion apparatus.

At present, the hand-held blowtorch that is used to heat, weld, cut has gas and oil blowtorch, acetylene burner, gas arc lamp, alcohol blast burner, and benzine blow lamp must pressurize and inflate preheating, flame is concentrated inadequately, above-mentioned blowtorch all needs special oxygen supply, and the equipment complexity is used inconvenient.

Existing liquefied petroleum gas combustion device as liquefied gas cooker, can not produce during burning and concentrate high temperature (1500 ℃) flame that sprays, and also is not easy to move at any time.

At present,,, lack a kind of effective weeding instrument,, lack a kind of simple and easy effective disinfection tool for its feeding field and zoo as artemisiifolia for pernicious evil grass.Up to now, do not see the oil liquefier hand-held blowtorch that is used for above-mentioned two aspects.

The purpose of this utility model is, a kind of oxygen supply in addition is provided, can produces and concentrate the liquefied petroleum gas hand-held burner that sprays thermal-flame, can be used for the sterilization of various small-sized welding, processing, heat treatment and weeding and cage for fowl and animal house.

Composition of the present utility model comprises liquefied petroleum gas steel cylinder, angle valve, pipe joint, flexible pipe, it is characterized in that flexible pipe connects ventilation handle, needle valve, fairlead and injector, and injector is made of nozzle, playpipe and injection cover.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the utility model general structure schematic diagram.

Fig. 2 and Fig. 3 partly cut open schematic diagram for the utility model ejector arrangements.

As shown in Figure 1, on the liquefied petroleum gas steel cylinder 1 angle valve 2 is arranged. Pipe joint 3, pipe joint connecting hose 4, flexible pipe connects successively ventilation handle 5, needle valve 6, fairlead 7 and sprays Device 8. The fairlead of ventilation handle and metal is set, and needle valve is contained in the handle front end, the operator can hold handle, and it is freely mobile to lift injector, and at any time controls the spray volume of liquefied petroleum gas.

As shown in Figures 2 and 3, injector is made up of nozzle 9, playpipe 11 and injection sheath 13 3 parts. Nozzle is common conical nozzle. The structure of playpipe comprises mixing 14, compression 15, trunnion 16, bright eruption mouth 17 4 parts, at least have three air inlet holes 10 on the mixing portion circumference, compression section is tubaeform space from large to small, trunnion is the elongated cylindrical pipeline, on trunnion front end circumference, have at least three gaseous mixture ventholes 12, the bright eruption mouth is conical nozzle (shown among Fig. 3 17), it perhaps is Laval nozzle (shown among Fig. 2 17), between trunnion 16 front ends and bright eruption mouth 17 and the injection sheath 13 toroidal cavity 18 is arranged, the injection sheath mouth of pipe is the little rear big horn mouth of elder generation.

The process that the utility model produces bright eruption is as follows: open angle valve 2 and needle valve 6, liquefied petroleum gas penetrates with the nozzle 9 of certain pressure from injector, mixing portion 14 at playpipe 11 mixes with certain proportion with the air that is entered by air inlet hole 10, because the compressed part 15 of air-flow produces negative pressure, so outside air is constantly sucked by air admission hole 10. Further fully mix during mist process trunnion 17, and to go out at a high speed bright eruption mouth 17, the toroidal cavity 18 that enters between playpipe and the injection sheath through trunnion front end gaseous mixture venthole 12 of sub-fraction air-flow wherein, igniting this moment namely produces at sleeve opening and concentrates the thermal-flame that sprays. At the trunnion front end gaseous mixture venthole being set, is stability and continuity in order to guarantee bright eruption. If the bright eruption mouth is common conical nozzle, then jet-impingement is slightly slow, and bright eruption is sharp and elongated. If jet is Laval nozzle, then jet-impingement is swift, bright eruption point and lacking, and the flame temperature height, no matter which kind of form jet is, the flame of ejection all is obvious three kinds of color levels, Show sufficient combustion, stable. Use general family expenses propane flammable gas, flame temperature can reach 1300 ℃, if use 99% pure propane flammable gas, flame temperature can reach 1650 ℃. Air consumption is about 40～60 Grams Per Hours.

Embodiment 1, and the utility model pipe joint is A ₃Steel is made, flexible pipe is the withstand voltage cotton sebific duct of oil resistant, the ventilation handle is that stainless steel is made, fairlead is a seamless steel pipe, and nozzle is manufactured with brass, and injection diameter is 0.10～0.15mm, playpipe and injection sheath are manufactured with aluminium alloy, playpipe mixing portion internal diameter is 9m m, and 6 air admission holes are arranged on the circumference, and the aperture is 3.5mm, the compression section taper angle is 30 °, internal diameter is gone to the bottom and is that 9mm, upper base are 5mm, and the trunnion internal diameter is with the compression section upper base, long 25mm, 3 gaseous mixture ventholes are arranged on its front end circumference, and the aperture is 1mm, and jet is a conical nozzle, taper angle is 7.5 °～10 °, the jet outlet diameter is 3mm, and the injection sheath internal diameter is 10mm, and mouth of pipe maximum inner diameter is 13mm.This burner is used for the welding processing of plastics and low-melting-point metal.If load liquefied petroleum gas steel cylinder with handcart, or adopt small-sized steel cylinder to carry, this burner is applicable to weeding and the sterilization of cage for fowl and animal house.

Embodiment 2, and nozzle bore is 0.20～0.25mm, and jet is a Laval nozzle, and all the other are with embodiment 1.This injector is applicable to glass, jewel and low-melting-point metal welding processing.

The utlity model has the advantages such as simple in structure, easy to use, of many uses, safe and reliable, with low cost.
