Description

Technical Field

[0001] The utility model relates to the technical field of liquid fuel burners, in particular to a multi-head atomizing swirl type liquid fuel commercial stove. Background Art

[0002] In addition to conventional gas combustion devices, a liquid fuel combustion device, such as mineral oils such as white oil, has also been proposed on the market. 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 the smooth combustion of white oil. For example, patent No. CN201921027103.1 discloses a burner that can use a variety of liquid fuels. It uses a high-pressure oil pump and a nozzle to spray liquid fuel into the furnace base, and uses a blower to blow air into the furnace base to ignite and burn the granular liquid fuel.

[0003] However, the liquid combustion structure requires the use of a high-pressure oil pump and a blower structure. In order to maintain the pressure resistance of the burner to the high-pressure oil and the mixed gas, cast iron or thicker metal materials are usually used. The burner is thick and bulky, not easy to move, occupies a large space, and has a high production cost, so further improvement is needed. Utility Model Content

[0029] Reference Figure 1 and Figure 2 The utility model proposes a multi-head atomizing swirl type liquid fuel commercial stove, comprising: a stove base 10, a gas distribution plate 20, a fire cover 30, a blower 40, an atomizer 50 and an oil tank;

[0030] An oil collecting chamber 11 is arranged around the furnace base 10, and the oil tank can supply oil to the oil collecting chamber 11; a gas distribution plate 20 is installed above the furnace base 10; a fire cover 30 is covered on the gas distribution plate 20, and is surrounded by a gas mixing chamber 21; a plurality of ejector tubes 22 are extended from the gas distribution plate 20 toward the oil collecting chamber 11; the ejector tube 22 is provided with an atomizer 50, which can convert the liquid fuel in the oil collecting chamber 11 into mist and send it toward the gas mixing chamber 21; the blower 40 can blow air toward the oil collecting chamber 11, and send it toward the gas mixing chamber 21 through the ejector tube 22.

[0031] In the utility model, an oil collecting chamber 11 in the shape of an inner furnace bag 15 is arranged below the furnace base 10, and the oil tank can deliver oil to the oil collecting chamber 11; a plurality of ejector tubes 22 are extended from the gas distribution plate 20 toward the oil collecting chamber 11, and the ejector tube 22 is provided with an atomizer 50, which can convert the liquid fuel in the oil collecting chamber 11 into mist and deliver it toward the mixing chamber 21; and the blower 40 can blow air into the oil collecting chamber 11, and simultaneously deliver it toward the mixing chamber 21 through the ejector tube 22, mix with the mist-like liquid fuel in the mixing chamber 21, and then deliver it through the fire cover 30 and burn; the liquid fuel attached to the inside of the gas distribution plate 20 passes downward through the ejector tube 22, and can drip into the oil collecting chamber 11 again for further combustion. The control center can conveniently and synchronously adjust the fuel suction and atomization rate and the air supplement and blowing rate by synchronously controlling the atomizer 50 and the blower 40, so as to maintain the optimal air-liquid-fuel ratio for combustion under different firepower levels.

[0032] The utility model can convert the liquid fuel in the oil collecting chamber 11 below the furnace base 10 into atomized fuel through the atomizer 50 of the ejector tube 22 and send it upward, and can send air upward by synchronously blowing air through the blower 40, so as to achieve the effect of mixing the atomized fuel and air and sending them upward for combustion; and the atomizers 50 of the multiple ejector tubes 22 can form multiple points in the mixing chamber 21 for fuel gas supply, and form a rotating fuel mixture to be sent upward through the fire cover 30, effectively improving the mixing efficiency of the fuel and air; the structure is simple, and there is no need to use a high-pressure oil pump. The furnace base 10 structure in the shape of an inner tank furnace bag 15 made of flat metal sheet metal and the gas distributor 20 can be embedded to form the main structure of the combustion stove, thereby reducing the overall volume of the commercial stove, reducing the weight, and effectively reducing the production cost.

[0033] In this embodiment, the gas distribution plate 20 is provided with a central cone 24 convexly disposed on the middle part of the gas distribution cavity, so that an annular groove structure is formed at the bottom of the mixing cavity 21. The gas outlet end of the ejector tube 22 is located in the annular groove, which can facilitate the formation of an annular rotating fuel mixture airflow, effectively improving the mixing efficiency of the fuel and air.

[0034] In this embodiment, the atomizer 50 is provided with oil-absorbing cotton 51, which extends toward the bottom of the oil collecting chamber 11. The oil-absorbing cotton 51 can be made into a rod or strip shape, extending toward the bottom of the oil collecting chamber 11, and can effectively absorb the fuel in the oil collecting chamber 11 to the atomizer 50 for atomization.

[0035] Preferably, the atomizer 50 is connected to an oil guide tube 52; the oil absorbing cotton 51 is in a cotton stick-shaped structure and is inserted into the oil guide tube 52. The oil absorbing cotton 51 can be conveniently plugged and installed.

[0039] Specifically, the fuel tank is provided with an oil pump, and the oil collecting chamber 11 is provided with an oil level sensor 14. The oil pump can continuously pump the fuel in the fuel tank to the oil inlet 12 of the oil collecting chamber 11. When the oil level sensor 14 determines that the oil level in the oil collecting chamber 11 is low, it can feedback a signal to the control center and start the oil pump synchronously.

[0040] In this embodiment, in order to form a uniform multi-point gas supply effect for the gas mixing chamber 21, a plurality of ejector tubes 22 are uniformly arranged along the circumferential direction below the gas distribution plate 20.

The flow divider 23 can block the gas outlet end of the ejector tube 22 to prevent the mixed gas from being directly sent to the fire hole of the fire cover 30, so that the fuel gas of the ejector tube 22 is sent to the side of the gas mixing chamber 21, so that multiple spiral ejector tubes 22 form a spiral mixed gas to form multiple mixed spiral rising airflows in the gas mixing chamber 21, and the airflow of the spiral mixed gas can rotate more times, further improving the mixing effect of fuel and air.

[0043] In this embodiment, the furnace base 10 includes a furnace bag 15 and a furnace panel 16; the furnace panel 16 is covered on the furnace bag 15 and surrounds the oil collecting chamber 11; the gas distribution plate 20 is embedded in the furnace panel 16.
