Background technology
Oil burner, on Burner design, normally configure the oil pump feed mode at present, so structure is comparatively complicated, and particularly in pulling portable firing equipment manufacturing industry, the drive source device of oil pump is a problem especially.
on March 11st, 1992, China utility model Granted publication CN2098620U, a kind of spray-type burner of gasified diesel that is proposed by TaiWan, China Changxin Machinery Ltd. is disclosed, its diesel oil nozzle tip partial design is cone-shaped, and at the sheathed atomizer of nozzle tip fit on, the nozzle lower end is connected with the burner high-pressure air pipe, make the nozzle tip pointed cone be inserted in the mesopore of nozzle tip, import pressure-air by burner base through high-pressure air pipe again, follow nozzle tip periphery breach and by the ejection of the inclined hole of middle hole peripheral, part is sprayed by the gap between nozzle tip tip and mesopore, the pencil shape diesel oil of ejection is atomized through cracking of pressure-air.The said firm finds that in implementation process there are some flaws in said structure, and thinking has: nozzle tip and flowline are welded and fixed together can't dismantle cleaning; The oil outlet aperture of nozzle tip is little is unfavorable for processing; Lack the defectives such as flame monitoring device.Then, on July 21st, 1993, the said firm advances improvement again at Chinese utility model Granted publication CN2138748Y to said structure, having proposed a kind of spray-type burner of gasified diesel of improvement, is mainly that the pressure-air of original bill and the circulation duct of fuel oil are exchanged; Establish pin thread and negative thread at the nozzle tip end, and respectively together with pipe joint and high-pressure air pipe are screwed onto; Nozzle tip and nozzle can be loaded and unloaded freely; Be provided with flame eye at the burner front end.Change in any case, the nozzle tip of above-mentioned two technical schemes all needs oil pressure, can predict, and the application of this device needs the drive source of oil pump.
The utility model content
The technical problems to be solved in the utility model is: for making up the deficiencies in the prior art, provide a kind of negative pressure for oil combustion device, this apparatus structure is simple, and combustion oil does not need oil pump to supply with, and is to make it produce the siphon fuel oil by negative pressure, reaches to reduce costs synergy.
The utility model has been taked following technical scheme and structural design.
A kind of negative pressure comprises air feed part, fuel feeding part and burner for oil combustion device; Described air feed partly is comprised of air pump and air accumulator; Be connected with check valve between air pump and air accumulator, establish safety valve on air accumulator; Described fuel feeding is partly to erect to fill a curved pipe and make the fuel outlet in case form the siphon outlet in fuel tank; Described burner is comprised of for oil burner nozzle and combustion chamber negative pressure, and negative pressure stretches in the combustion chamber for the mouth of oil burner nozzle, also is provided with igniter in the combustion chamber; Described negative pressure is counted a cone-shaped air nozzle for oil burner nozzle, and concentric coordinates a sheathed fuel oil supply nozzle outside air nozzle; The air accumulator of above-mentioned air feed part is connected negative pressure for the air nozzle on oil burner nozzle with tracheae by air valve; The curved pipe of above-mentioned fuel feeding part is connected negative pressure for the fuel oil supply nozzle on oil burner nozzle by the fuel tap door with oil pipe.
Further, above-mentioned negative pressure is greater than the external diameter of air nozzle cone mouth for the internal diameter of fuel oil supply nozzle mouth on oil burner nozzle; Make between the outer rim of the inner edge of fuel oil supply nozzle mouth and air nozzle cone mouth and form the ring-type spout.
The utility model has been taked technique scheme and structural design, and air pump and air accumulator provide pressure gas to negative pressure for oil burner nozzle; Fuel feeding part oil pipe provides combustion oil to negative pressure for oil burner nozzle; Gases at high pressure spray through air nozzle, and at the ring-type nozzle formation jet flow negative pressure of fuel oil supply nozzle, the ring-type spout that combustion oil follows fuel oil supply nozzle atomizes through cracking of pressure-air, enters the combustion chamber and realizes burning.Negative pressure makes it partly produce the siphon fuel oil at fuel feeding for the jet flow negative pressure of oil burner nozzle.Therefore combustion oil does not need oil pump to supply with, and reaches simplified structure, reduces costs the purpose of synergy.
The utlity model has the advantages such as reasonable in design, simple in structure, simple for production, that combustion efficiency is good, product cost is low, gone into operation in the portable firing equipment of our company on probation.Also can promote the use of in other firing equipment manufacturing industry simultaneously.
