Description

Fuel oil heating air-heater

The utility model relates to a kind ofly makes the heating device of fuel with light diesel fuel or kerosene, the fuel oil heating air-heater of particularly a kind of motor vehicle that can be used for various no warming by air conditioner facilities and field work prefabricated house etc.

At present, utilize air-heater heating and defrosting in the motor vehicle envelope of some no warming by air conditioner facilities and in the prefabricated house of field work.Existing air-heater generally adopts the directly-heated type heating, and promptly fuel oil oil is chewed the direct injection burning, blows out hot blast by blower fan again.Preserve due proportion because of it can not make oil, gas mixing ratio, so fuel atomization effect is not good, this is excessive fuel consumption not only, and the unit interval fuel consumption is big, burning time is long, and it is insufficient to burn, over-emitting black exhaust, contaminated environment.In addition, because of the spray-type fuel oil pump volume is big, so the complete machine housing more greatly, heavier, it is big to take up room, inconvenience is installed.

The purpose of this utility model provides a kind of improved fuel oil heating air-heater, its compact conformation, and volume is little, in light weight, not only economize on electricity, fuel-economizing, saving space, be convenient to install, and sufficient combustion, thermal efficiency height effectively reduces the pollution to environment, significantly improves heating effect.

The purpose of this utility model is achieved in that this device comprises body and assembles its interior motor, fan, oil pump, wherein the main chamber peripheral ring is wound with the jacket type subsidiary combustion chamber that is communicated with it, and atomizing disk and the atomizing wheel that is packed on the oil pump shaft arranged in the fuel-oil atmozation mixing chamber that communicates with the pumping chamber.

Because the utility model adopts same motor-driven fan and oil pump, and installs atomizing disk and atomizing wheel on oil pump shaft, institute is so that this apparatus structure is compact more, its volume ratio like product is few more than 1/5, weight only be its 1/2, both economized on electricity, saved the space, be convenient to again install.Because of the disc that can make the fuel oil primary atomization and the retaining oil tanker of secondary-atomizing are arranged in the fuel-oil atmozation mixing chamber, fuel oil is after through twice atomizing, be subjected to the suction function of the forced draft formation of pumping chamber's ejection, rapid expanded increase gasification result, quantitatively fuel oil is mixed mutually with quantitative combustion air in the forced draft, be enough to make the fuel oil that is gasified totally fully to burn, so but fuel-economizing reduces the pollution to environment.The main chamber peripheral ring of this device around subsidiary combustion chamber be the chuck shape, high-temperature combustion gas enters subsidiary combustion chamber from main chamber through passage, further burning after carrying out heat exchange with the chuck cold air on every side of flowing through, is discharged outside the body from the exhaust opening of subsidiary combustion chamber end.The cold air that fan sucks enters in the body and absorbs heat along main chamber perisporium, subsidiary combustion chamber chuck wall, discharges from hot-blast outlet.Since cold air in body with the contact area showed increased of major and minor combustion chamber hot wall, so effectively improved heat exchange effect and heating capacity.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure schematic diagram of the utility model.

Describe concrete structure of the present utility model in detail according to Fig. 1.This device comprises the parts such as body 4, fan 2, motor 3, oil pump 6, atomising device and burner that have cold air inlet 1 and hot-blast outlet 13.Wherein motor 3 adopts direct current generator, and present embodiment is selected double-speed motor for use, can produce strong retaining hot blast and weak shelves hot blast, also can adopt other buncher as required.Oil pump 6 adopts worm gear, worm speed-down oil pump, is input to fuel feed pump 18 with the control fuel oil quantitatively after oil inlet pipe 21 sucks, and guarantees required fuel delivery in the atomizing disk.Install fan 2 at the left side of same motor 3 output axle head, right output axle head connects the input of oil pump shaft by shaft coupling.Install the supercharging impeller 7 of pumping chamber 8 on the output of oil pump shaft.The air inlet of supercharging impeller is communicated with atmosphere by air inlet pipe 20.With in the fuel-oil atmozation mixing chamber 15 that pumping chamber 8 communicates atomising device atomizing disk 16 and the atomizing wheel 9 that is packed on the oil pump shaft arranged.Fuel oil drips on the atomizing disk 16 of high speed rotating from fuel feed pump 18, atomized for the first time, be thrown to again and carry out second time atomizing on the atomizing wheel 9, be subjected to the suction function that the forced draft of pumping chamber's 8 ejections forms, expanded being inhaled in the mixing chamber 15 rapidly through the fuel oil of twice atomizing.That quantitatively provide and the fuel oil that has been atomized of fuel feed pump 18 with enter the quantitative combustion air that supercharging impeller 7 produces the forced drafts from air inlet pipe 20, spray into simultaneously and keep being mixed of quantitative ratio in the mixing chamber 15, form the fuel oil that is gasified totally and ignited by igniter plug 17 and enter burner and fully burn.For preventing that fuel oil from lighting preceding or flame-out back oil droplet in mixing chamber 15 internal causes and gathering, the oil dripping tube 19 of oil extraction is set in mixing chamber 15 bottoms.Burner comprises main chamber 14, subsidiary combustion chamber 5.The jacket type subsidiary combustion chamber 5 that is packed in the body 4 is looped around main chamber 14 peripheries, and utilizes passage 11 to be connected.Main chamber end portion encloses fluid dividing cover 12, the passage 11 so that burning gases are flowed through smoothly.Go in the mixing chamber 15 for preventing that combustion gas in the main chamber 14 is contrary, the cage 10 of band through hole in the middle of between two Room, being provided with, make the combustion gas that is gasified totally in the mixing chamber 15 by after lighting immediately the through hole from cage 10 enter main chamber 14 internal combustion, be beneficial to combustion gas and in mixing chamber, continuously be gasified totally, guarantee that fuel oil fully burns.The fuel gas that the continuous mixed chamber 15 of burning gases in the main chamber 14 sprays into is discharged outside the body 4 along the exhaust opening 22 of subsidiary combustion chamber 5 ends after passage 11 heads into subsidiary combustion chamber 5 completing combustions.Meanwhile, cold air is sucked by fan 2 and sails against the current along major and minor chamber wall direction of heat flow, fully carries out heat exchange, and cold air becomes hot blast rapidly, blow out from the hot-blast outlet 13 of body 4 ends, with heat delivery to required place.
