Description

Technical Field

[0001] The utility model relates to the field of liquid fuel burner technology, in particular to a liquid fuel cartridge furnace with oil adsorption, oil return, and atomization combustion. Background Art

[0002] In addition to conventional gas combustion devices, there are also liquid fuel combustion devices on the market, such as mineral oils such as white oil. This liquid combustion device achieves combustion by atomizing and igniting the atomized gas. During the combustion process, the atomized white oil is easily liquefied into liquid fuel again and remains in the burner. A matching combustion structure needs to be set to ensure smooth combustion of white oil.

[0003] Existing liquid fuel combustion devices usually use fuel storage tanks. As the fuel is consumed, a certain negative pressure will be formed in the tank. When the negative pressure drops to a certain level, the fuel cannot be released. In the end, some of the fuel cannot be used and is wasted.

[0004] In addition, during the use of the oil burner, fuel will adhere to the inner walls of the burner and the inner walls of the ejector tube. Generally, the fuel will be drained to the auxiliary fuel tank through the oil drain pipe. If the oil drain pipe is blocked, the fuel will block the atomizing gas passage, and the concentration of the mixed gas at the burner nozzle will change, resulting in incomplete combustion, black smoke, and carbon deposits at the nozzle blocking the fire hole, causing deflagration.

[0033] The furnace head 10 includes a furnace base 11 and an ejector tube 12; the furnace base 11 is provided with an air supply mixing chamber 13 connected to the air outlet end of the ejector tube 12; the atomizing gas mixing box 30 is provided at the air inlet end of the ejector tube 12;

[0034] The atomizing gas mixing box 30 includes an air blowing port 31, an oil inlet 32, an oil return vent hole 33, an oil inlet chamber 34 and a gas mixing chamber 35; the air blowing port 31 is connected to the blower 50 and communicates with the gas mixing chamber 35; the oil inlet 32 ​​is connected to the oil outlet 21 of the oil tank 20 and communicates with the oil inlet chamber 34;

[0035] The oil return vent hole 33 is opened above the oil inlet chamber 34; the atomizer 40 is installed on the atomizing mixing box 30, which can convert the liquid fuel in the oil inlet chamber 34 into mist and send it toward the mixing chamber 35; the blower 50 can blow air toward the mixing chamber 35; the atomizer 40 and the blower 50 are electrically connected to the control center.

[0036] In the utility model, the fuel in the fuel tank 20 can flow to the fuel inlet chamber 34 through the fuel outlet 21 via the pipeline and the fuel inlet 32; then, the atomizer 40 converts the fuel in the fuel inlet chamber 34 into mist and sends it toward the mixing chamber 35; the blower 50 can blow air toward the mixing chamber 35 through the pipeline and the blowing port 31, so that the air and the misted liquid fuel are sent toward the ejector tube 12 for combustion. The control center can conveniently and synchronously adjust the fuel suction and atomization rate and the air supplement and blowing rate through synchronous control of the atomizer 40 and the blower 50, so as to maintain a better air-liquid-fuel ratio for combustion under different firepower levels.

[0037] In the present invention, the oil return air hole 33 has two functions; on the one hand, after the mist fuel is attached to the injector tube 12, it can flow downward to the oil return air hole 33 of the atomizing mixing box 30, and can be refluxed and collected in the oil inlet chamber 34, and then atomized and output again; on the other hand, the connecting pipeline of the fuel tank 20 adopts a large-diameter pipeline, and the oil return air hole 33 can be connected to the air in the mixing chamber 35, and the air flows into the fuel tank 20 through the pipeline, so that the fuel in the fuel tank 20 can flow smoothly into the oil inlet chamber 34; and when the oil level in the oil inlet chamber 34 rises to completely block the oil return air hole 33, a certain negative pressure is formed in the oil inlet chamber 34 and the fuel tank 20, and the oil level in the oil inlet chamber 34 cannot rise again, so as to control the oil level of the fuel inlet tank 20 and avoid fuel overflow. At the same time, the structure of the fuel tank 20 can be simplified, and the fuel can be output with a single oil inlet pipe.
