Description

Technical Field

[0001] This utility model relates to the field of civilian stove technology, specifically to an open-type gasification burner. Background Technology

[0002] The ethylene glycol liquid vaporization burner head is a core component designed specifically for high-viscosity, high-boiling-point ethylene glycol fuel. It converts liquid ethylene glycol into combustible gas through heating and atomization technology, achieving efficient combustion.

[0003] Traditional ethylene glycol liquid vaporization burners currently on the market have two combustion methods: vaporization combustion, which relies on self-heating or electric heating to turn oil into gas for combustion, takes 5-8 minutes to heat to 300 degrees Celsius, which is a long waiting time. If the oil is not clean, it is easy to clog the nozzle. The heating pipe is also prone to clogging due to the long time, resulting in a high failure rate. External heaters require an additional controller and require 3-5 minutes to reach the temperature of 300 degrees Celsius before pulse ignition. Then, a fan blows the fuel in the burner into the inner liner for atomized combustion.

[0004] Regarding the above description, the applicant believes the following problems exist: Due to the high flash point of ethylene glycol vegetable oil, traditional ethylene glycol liquid vaporization burners require heating with alcohol for 3-5 minutes (alcohol is easily flammable and unsafe) before adding ethylene glycol vegetable oil to the burner for normal use. Furthermore, the burner uses a 90-100mm atomizing burner head, which is too large, and the fan power is insufficient, resulting in insufficient firepower and incomplete combustion. This not only fails to save energy but also causes air pollution and significant energy waste. Additionally, the ignition time is slow (3-5 minutes after ignition) and the extinguishing time is slow (the remaining oil continues to burn for 3-5 minutes after extinguishing). Moreover, traditional ethylene glycol liquid vaporization burners using 220V heating elements and heating rods are prone to damage and electrical leakage, posing a safety hazard. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an open-type gasification burner head, which features instantaneous ignition via an igniter plug and rapid heating via a combustion-supporting metal mesh. After ignition, it immediately enters normal combustion without waiting. By reducing the combustion chamber diameter from the traditional 90-100mm to 80mm, the reduced combustion space allows for a more concentrated distribution of fuel droplets within the combustion chamber, resulting in a more uniform contact area with the combustion air. This, combined with the snail fan's airflow, ensures more thorough fuel-air mixing, thereby improving firepower. The model also features a design that utilizes… Replacing the traditional 220V heating element and heating rod with a 12V safe voltage completely eliminates the risk of electric leakage, eliminates easily damaged heating rod components, and reduces maintenance problems caused by easily damaged heating elements. At the same time, by stopping the fuel supply and the fan simultaneously when the flame is turned off, the 3-5 minute delay in the combustion of residual oil is avoided, thus preventing safety hazards caused by residual heat. By setting up a gasification-aiding metal mesh and a snail fan, the fuel gasification is more complete, the combustion efficiency is improved compared to traditional burners, the emission of unburned pollutants is reduced, and the fuel consumption is reduced, thereby reducing energy waste.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An open-type gasification burner head includes a cast iron burner head shell, a cast iron burner head inner liner, and a ventilation assembly. A hanging lug is fixedly connected to the outer side of the cast iron burner head shell. A ventilation assembly is installed inside the cast iron burner head shell. The cast iron burner head inner liner is fixedly connected to the inside of the cast iron burner head shell. A gasification combustion-supporting metal mesh is fixedly connected to the inside of the gasification combustion-supporting metal mesh. A heating ignition plug is fixedly connected to the inside of the gasification combustion-supporting metal mesh. A return oil pipe is fixedly connected to the inside of the cast iron burner head inner liner. An external oil inlet pipe is fixedly connected to the outside of the cast iron burner head shell. A bottom oil inlet pipe is fixedly connected to one side of the external oil inlet pipe. A controller is electrically connected to the outside of the cast iron burner head shell. An oil nozzle is fixedly connected to the top of the bottom oil inlet pipe.

[0008] In one optional embodiment, three sets of hanging ears are provided, and the three sets of hanging ears are evenly arranged in a circumferential array on the outside of the cast iron furnace head shell, and the combustion chamber of the cast iron furnace head liner has a diameter of eighty millimeters.

[0009] In one optional embodiment, a through hole is provided on the outer shell of the cast iron furnace head, and the oil return pipe passes through the through hole and is disposed inside the outer shell of the cast iron furnace head.

[0010] In one optional embodiment, a through hole two is provided on the outer shell of the cast iron furnace head and the inner liner of the cast iron furnace head, and the bottom oil inlet pipe is connected to the external oil inlet pipe through the through hole two.

[0011] In one optional embodiment, the ventilation assembly includes an exhaust vent located on the inner liner of the cast iron furnace head, an air inlet pipe fixedly connected to the bottom of the cast iron furnace head shell, and an exhaust pipe fixedly connected to the bottom of the cast iron furnace head shell.

[0012] In one optional embodiment, a through hole three is provided on the inner liner of the cast iron furnace head, and the air inlet pipe is fixedly connected to the inner liner of the cast iron furnace head through the through hole three.

[0013] In one optional embodiment, three sets of exhaust vents are provided, which are evenly distributed on the inner liner of the cast iron furnace head, and the exhaust pipe is fixedly connected to the bottom of the inner liner of the cast iron furnace head and communicates with the exhaust vents.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 2. This device uses a safe 12-volt power supply to avoid the risk of electric leakage, eliminates the need for easily damaged heating rod components, and reduces maintenance problems caused by the easy failure of heating elements. The controller outputs voltage to the heating ignition plug, causing it to heat up to 1200 degrees Celsius instantly. At the same time, the oil pump starts to draw liquid fuel and pumps it into the bottom oil inlet pipe through the external oil inlet pipe. Then, the fuel injector begins to precisely spray liquid fuel onto the vaporization and combustion-supporting metal mesh. Subsequently, the heating ignition plug directly ignites the fuel on the vaporization and combustion-supporting metal mesh, so that there is no waiting time after ignition and it immediately enters the normal combustion state. By reducing the diameter of the combustion chamber from the traditional 90 to 100 mm to 80 mm, the combustion space is reduced, making the fuel droplets more concentrated in the combustion chamber and the contact area with the combustion-supporting air more uniform. This matches the air volume of the snail fan, and the fuel and air mix more thoroughly, which helps to improve the firepower.

[0016] 1. After initial combustion of the fuel, the snail fan is activated by the controller, delivering a stable airflow to the gasification and combustion-supporting metal mesh area through the air inlet pipe. This propels the fuel to complete open gasification on the surface of the metal mesh. The gasified fuel mixes thoroughly with air, achieving efficient combustion and thus improving combustion efficiency. This reduces unburned pollutant emissions and lowers fuel consumption, balancing environmental protection and economy. The controller can adjust the oil pump supply and fan airflow in real time, enabling precise switching between large and small flames. When shutting off, simply turn the controller knob; the oil pump and fan immediately stop working, and the flame extinguishes without delay, eliminating the need for additional residual oil handling. Incompletely gasified fuel can be returned to the oil storage device through the return oil pipe. The controller circuit also features a secondary heating ignition function, which, combined with the return oil pipe design, ensures stable ignition even at low temperatures or with residual fuel, while avoiding the risk of fuel leakage, thus improving safety. When the device is shut down, exhaust gas and smoke are discharged through the exhaust vent into the exhaust pipe to prevent backfire, thereby protecting the device. Attached Figure Description

A hanging lug 2 is fixedly connected to the outer side of the cast iron furnace head shell 1. A ventilation assembly is provided inside the cast iron furnace head shell 1. The cast iron furnace head inner liner 301 is fixedly connected inside the cast iron furnace head shell 1.

A heating ignition plug 305 is fixedly connected inside the gasification combustion-supporting metal mesh 304. The cast iron furnace head inner liner 301... An internal return oil pipe 303 is fixedly connected. An external oil inlet pipe 302 is fixedly connected to the outside of the cast iron furnace head shell 1. A bottom oil inlet pipe 306 is fixedly connected to one side of the external oil inlet pipe 302. A controller is electrically connected to the outside of the cast iron furnace head shell 1. An oil nozzle 307 is fixedly connected to the top of the bottom oil inlet pipe 306. The controller is externally installed on this device. The external oil inlet pipe 302 is externally connected to the oil pump. The external return oil pipe 303 is externally connected to the oil storage tank. One side of the air inlet pipe 403 is fixedly connected to the air outlet pipe of the snail fan. The device is powered by a safe 12-volt supply. The controller outputs voltage to the ignition plug 305, instantly heating it to a high temperature of 1200 degrees Celsius. Simultaneously, the fuel pump begins drawing liquid fuel, pumping it through the external fuel inlet pipe 302 into the bottom fuel inlet pipe 306. Then, the fuel injector 307 precisely sprays the liquid fuel onto the vaporization combustion-supporting metal mesh 304. The ignition plug 305 then directly ignites the fuel on the vaporization combustion-supporting metal mesh 304. After initial combustion, the ventilation system is activated to allow the vaporized fuel to mix with... The air is fully mixed to achieve efficient combustion. At the same time, the controller can adjust the oil pump supply and the fan volume in real time to achieve precise switching between large and small flames.

No additional treatment of residual oil is required. Meanwhile, the fuel that is not completely vaporized can flow back to the oil storage device through the return oil pipe 303. The controller circuit is equipped with a secondary heating ignition function. With the design of the return oil pipe 303, it can ensure stable ignition even at low temperatures or when there is fuel residue, while avoiding the risk of fuel leakage, thereby improving safety.

[0028] In a preferred embodiment of this utility model, three sets of hanging ears 2 are provided. The three sets of hanging ears 2 are evenly arranged in a circular array on the outside of the cast iron furnace head shell 1. The diameter of the combustion chamber of the cast iron furnace head inner liner 301 is 80 mm, which makes it convenient for the user to install the device in a designated position through the hanging ears 2. By reducing the combustion space, the fuel droplets are more concentrated in the combustion chamber and the contact area with the combustion air is more uniform. Combined with the open gasification combustion design, the residue of unburned fuel can be greatly reduced, which not only reduces air pollution, but also improves the combustion efficiency of the device.

[0029] In a preferred embodiment of this utility model, a through hole is provided on the cast iron furnace head shell 1, and the oil return pipe 303 passes through the through hole and is located inside the cast iron furnace head shell 1, so that the incompletely gasified fuel can flow back to the oil storage device through the oil return pipe 303, thereby avoiding fuel leakage.

[0030] In a preferred embodiment of this utility model, a through hole 2 is provided on the cast iron furnace head shell 1 and the cast iron furnace head inner liner 301. The bottom oil inlet pipe 306 is connected to the external oil inlet pipe 302 through the through hole 2, which is conducive to the oil pump pumping liquid fuel into the bottom oil inlet pipe 306 through the external oil inlet pipe 302, which is conducive to the precise spraying of liquid fuel onto the gasification and combustion-supporting metal mesh 304 by the oil injector 307.

[0031] Please see Figure 2 and Figure 5 In this embodiment, the ventilation assembly includes an exhaust port 401, which is located on the inner liner 301 of the cast iron furnace head. An air inlet pipe 403 is fixedly connected to the bottom of the outer shell 1 of the cast iron furnace head, and an exhaust pipe 402 is fixedly connected to the bottom of the outer shell 1 of the cast iron furnace head. The snail fan is started by the controller, and a stable airflow is delivered to the gasification and combustion-supporting metal mesh 304 area through the air inlet pipe 403. This propels the fuel to complete open gasification on the surface of the gasification and combustion-supporting metal mesh 304. The gasified fuel is fully mixed with air to achieve efficient combustion. At the same time, when the device is closed, the exhaust gas and dust in the device are discharged through the exhaust port 401 to the exhaust pipe 402 to prevent backfire of the flue gas, thereby helping to protect the device.

[0032] In a preferred embodiment of this utility model, a through hole three is provided on the inner liner 301 of the cast iron furnace head, and the air inlet pipe 403 is fixedly connected to the inner liner 301 of the cast iron furnace head through the through hole three. This facilitates the snail fan to deliver a stable airflow to the gasification combustion-supporting metal mesh 304 area through the air inlet pipe 403, which in turn facilitates the full mixing of the gasified fuel and air to achieve efficient combustion.

[0033] In a preferred embodiment of this utility model, three sets of exhaust vents 401 are provided, and the three sets of exhaust vents 401 are evenly opened on the inner liner 301 of the cast iron furnace head. The exhaust pipe 402 is fixedly connected to the bottom of the inner liner 301 of the cast iron furnace head and communicates with the exhaust vents 401.

[0034] During operation, this device is equipped with an external controller. The external oil inlet pipe 302 is connected to the oil pump, and the external oil return pipe 303 is connected to the oil storage tank. One side of the air inlet pipe 403 is fixedly connected to the air outlet pipe of the snail fan. The controller is electrically connected to the oil pump, the snail fan, and the heating ignition plug 305.

The controller outputs voltage to the ignition plug 305, causing it to instantly heat up to a high temperature of 1200 degrees Celsius. The core heating element of the ignition plug 305 is made of iron-chromium-aluminum alloy and uses resistance heating. Simultaneously, the fuel pump begins to draw in liquid fuel, pumping it through the external fuel inlet pipe 302 into the bottom fuel inlet pipe 306. Then, the fuel injector 307 precisely sprays the liquid fuel onto the vaporization combustion-supporting metal mesh 304. The ignition plug 305 then directly ignites the fuel on the vaporization combustion-supporting metal mesh 304, thus igniting the fuel. Without waiting, it immediately enters normal combustion mode. After initial combustion, the controller starts the snail fan, which delivers a stable airflow to the gasification combustion-supporting metal mesh 304 area through the air inlet pipe 403. This propels the fuel to complete open gasification on the surface of the gasification combustion-supporting metal mesh 304. The gasified fuel mixes thoroughly with air, achieving efficient combustion and thus improving combustion efficiency. This reduces unburned pollutant emissions and lowers fuel consumption, balancing environmental protection and economy. The controller can also adjust the fuel pump supply and fan airflow in real time, enabling precise switching between large and small flames. Upon flameout... Simply turn the controller knob, and the oil pump and fan will immediately stop working, the flame will extinguish without delay, and no additional treatment of residual oil is required. At the same time, the incompletely vaporized fuel can flow back to the oil storage device through the return oil pipe 303. The controller circuit is equipped with a secondary heating ignition function, which, together with the design of the return oil pipe 303, ensures stable ignition even at low temperatures or when there is residual fuel, while avoiding the risk of fuel leakage, thereby improving safety. When the device is shut down, the exhaust gas and dust in the device are discharged into the exhaust pipe 402 through the exhaust port 401 to prevent backfire of the flue gas, thus helping to protect the device.
