Description

Technical Field

[0001] The utility model relates to the field of liquid burners, in particular to a commercial liquid fuel burner with an oil-gas mixed blast structure. Background Art

[0002] Currently, household stoves use liquefied coal gas, natural gas, and methanol stoves, all of which use fuels that are flammable and explosive. Leakage during use can cause carbon monoxide poisoning and ignite with an open flame, posing a serious threat to people's lives and property. White oil, a type of mineral oil, is a new combustion energy source. It has a high calorific value and is inflammable and explosive, making it non-flammable. These liquid fuels lack dedicated pressure atomization devices and instead use electronic ignition devices to generate a high-voltage arc. Because the liquid fuel is not atomized and properly mixed with air, the success rate of ignition is low when the stove is cold. To adapt to the combustion of white oil and other mineral oils, an improved burner with a more rational air supply structure suitable for liquid fuels is sought. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a commercial liquid fuel burner with an oil-gas mixed blast structure.

[0005] The burner is a vertical cylindrical structure, which is divided into a combustion chamber and an ignition blast chamber by a partition. The fuel nozzle and the ignition plug are arranged on one side of the ignition blast chamber. The ignition blast chamber is located in the blast box, and the blower can supply air to the blast box.

[0006] The oil-gas mixing three-way joint is respectively connected to an oil pump, an air pump and the fuel nozzle; the oil pump and the air pump can respectively pump liquid fuel and high-pressure gas into the oil-gas mixing three-way joint, and spray them into the ignition blast chamber through the fuel nozzle.

[0007] Optionally, the ignition blast chamber is provided with an air guide spindle; the air guide spindle is provided with a plurality of spiral air guide blades, which can form a spiral airflow and send it upward to the combustion chamber.

[0008] Optionally, a noise reduction and sound insulation layer is provided on the inner wall of the combustion chamber.

[0009] Optionally, the noise reduction and sound insulation layer is a multi-layer metal wire mesh structure attached to the inner wall of the combustion chamber.

[0021] Example

[0022] Reference Figure 1 The utility model proposes a commercial liquid fuel burner with an oil-gas mixing blast structure, comprising: a burner head 10, a blast box 20, a blower 21, an oil-gas mixing three-way joint 30, a fuel nozzle 40 and an ignition plug;

[0023] The burner 10 is a vertical cylindrical structure, divided into a combustion chamber 11 and an ignition blast chamber 12 by a partition. The fuel nozzle 40 and the ignition plug are arranged on one side of the ignition blast chamber 12. The ignition blast chamber 12 is located in the blast box 20, and the blower 21 can supply air to the blast box 20.

[0024] The oil-gas mixing three-way joint 30 is respectively connected to an oil pump 60 , an air pump 70 and the fuel nozzle 40 ; the oil pump 60 and the air pump 70 can respectively pump liquid fuel and high-pressure gas into the oil-gas mixing three-way joint 30 , and spray them into the ignition blast chamber 12 through the fuel nozzle 40 .

[0025] In the present invention, the oil pump 60 and the air pump 70 can respectively pump liquid fuel and high-pressure gas into the oil-gas mixing three-way joint 30, and spray them into the ignition blast chamber 12 through the fuel nozzle 40. The high-pressure and high-speed vaporized liquid fuel can effectively contact with the air, and the ignition success rate is high; under the action of the blower box 20 and the blower 21, a sufficient amount of air can be blown into the ignition blast chamber 12 at the lower part of the burner 10 for combustion, so that the air is supplied and transported from bottom to top, and a fierce fire combustion effect of direct injection upward is formed through the vertical cylindrical combustion chamber 11. For different types of liquid fuel oils, it can ensure a better ignition effect while forming a fierce fire combustion effect.

[0026] The oil pump 60 can be a pulse oil pump used in conjunction with a 12V, 24V or 220V circuit.

[0027] In this embodiment, the ignition blast chamber 12 is provided with an air guide vortex seat 13. The air guide vortex seat 13 is provided with a plurality of spiral air guide vanes, which can form a spiral airflow that is sent upward to the combustion chamber 11. The spiral airflow formed by the air guide vortex seat 13 can more thoroughly mix the vaporized liquid fuel with the air, and then rotate upward to be ejected and burned at the top of the combustion chamber 11.

[0028] In this embodiment, in order to reduce the airflow and combustion noise of the low-speed rotating airflow, a noise reduction and sound insulation layer 14 is provided on the inner wall of the combustion chamber 11 .

[0029] Specifically, the noise reduction and sound insulation layer 14 is a multi-layer metal mesh structure attached to the inner wall of the combustion chamber 11. The multi-layer metal mesh structure can prevent the sound waves generated by the explosion of gas in the combustion chamber 11 from spreading outward, thereby reducing the noise generated by the burner during combustion.

[0030] In this embodiment, the burner head 10 is provided with a flameout protection probe 50. When there is no flame in the combustion chamber 11, the flameout protection probe can be linked to the oil pump 60 to stop working, thereby preventing liquid fuel from accumulating in the blast box 20 and the burner head 10.

[0031] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
