Description

Technical Field

[0001] The utility model relates to the field of stoves, in particular to a liquid fuel ion combustion body. Background Art

[0002] At present, the liquid fuel stoves are mainly electronic fuel stoves in terms of fuel supply. They are mainly used in a series of commercial high-fire stoves, such as Chinese cooking stoves and large pot stoves. They are also used in other kitchen stoves such as steamers, stew barrels, cooking stoves, clay pot stoves, and heaters. The fuel is vaporized by a pulse oil pump. The combustion method of electronic fuel stoves requires that the liquid fuel must be pressurized to 12 kg to ensure that the liquid fuel sprayed from the atomizing nozzle is in a mist form. The mist liquid fuel can be mixed with the air injected by the fan in the wind cavity of the stove to burn. The electronic fuel injection method will speed up the circulation of the atomized liquid. Therefore, it is often seen that when many commercial stoves are using high fire, the flame sprays from the side of the pot, resulting in a waste of heat energy. How to ensure that the liquid fuel can be fully burned and released in the stove basin is a technical problem that needs to be solved urgently.

[0003] Therefore, our company developed the first generation of liquid fuel stoves, see CN202410224133.0, a multi-stage silent energy-saving combustion device for liquid fuel. This product essentially changes the atomization combustion mode of the original electric fuel injection stove through the structural design of the ion combustion body, and changes the original open combustion mode of the electric fuel injection stove into a closed multi-stage combustion mode. It does not need to be atomized by a high-pressure atomizing nozzle. It uses the temperature generated by the primary combustion of the first-stage combustion chamber in the ion combustion body and cooperates with the intake of the cyclone intake cylinder to achieve true high-temperature vaporization of the liquid fuel, and The sub-combustion body, the lower ring of the combustion tube and the ion fire-dividing teeth are stably burned and fully vaporized in the secondary combustion chamber, and fully burned and heated in the tertiary combustion chamber in the combustion tube, so that the liquid fuel is fully burned. The combustion device is no longer directly heated by flames, but the fuel is heated by thermal radiation after full combustion. Compared with direct heating by flames, the heating effect is better, which greatly improves the heat utilization rate and greatly reduces the heat energy loss. Compared with electric spray stoves, the heat utilization rate is nearly doubled, and the energy consumption such as oil and electricity is only half of the original, and it is safer, independent and widely applicable. In addition, when performing low-fire mode and slow-fire combustion, the liquid fuel can stably fission and burn on the ion fire-dividing teeth in the secondary combustion chamber to continuously generate stable heat.

[0004] However, the ion combustion body of this product has the following defects:

[0005] 1. Since the base, vaporization combustion cylinder and cyclone air intake cylinder are integrally cast, the annular oil passage is not easy to cast and needs to be polished after casting, which is troublesome to process.

[0006] 2. After the liquid fuel inlet pipe enters the annular oil circuit, it cannot completely penetrate the entire annular oil circuit due to the effect of the cyclone wind.

[0007] 3. The atomizing combustion network only covers the annular oil circuit, and the oil film area formed is limited.

[0008] Therefore, there is an urgent need to further upgrade and optimize the product structure. Utility Model Content

[0025] The utility model will be further described below, specifically as follows:

[0026] A liquid fuel ion burner, see Figures 1 to 3, including a base, a vaporization combustion tube 2 and a cyclone air inlet tube 3 are provided on the top surface of the base 1, the vaporization combustion tube 2 and the base 1 are integrally formed, the cyclone air inlet tube 3 is located at the center of the base 1, and is located in the vaporization combustion tube 2, a vaporization combustion chamber is left between the inner wall of the vaporization combustion tube 2 and the outer wall of the cyclone air inlet tube 3, an oil inlet 12 is opened on the side of the base 1, the oil inlet 12 is connected with the inside of the vaporization combustion chamber, liquid fuel is directly injected into the vaporization combustion chamber through the oil inlet 12, a circle of annular atomization combustion net 5 is provided in the vaporization combustion tube 2, and the size of the atomization combustion net 5 matches the inner wall of the vaporization combustion tube 2.

[0027] The ion combustion body of the first generation product developed by our company has a ring-shaped oil path on the inner wall of the vaporization combustion tube 2, and a circle of atomization combustion net 5 is welded on the oil path. After the liquid fuel enters from the oil inlet 12, it first enters the ring-shaped oil path, then adheres to the atomization combustion net 58, and then mixes with the cyclone for combustion. However, the present invention does not have a ring-shaped oil path, firstly because it is difficult to open the oil path on the inner wall and it is inconvenient to process, and secondly because the oil path is too narrow, the area of ​​the atomization combustion net 5 laid will not be very large, and the area of ​​the oil film formed is limited.

[0028] The utility model directly designs a circle of annular atomizing combustion net 5 on the inner wall of the vaporizing combustion tube 2, and the height of the atomizing combustion net 5 can be flush with the height of the vaporizing combustion tube 2, and its area is greatly increased, which greatly increases the adhesion area of ​​the oil film. A gap is left between the atomizing combustion net 5 and the inner wall of the vaporizing combustion tube 2, which is conducive to the diffusion of liquid fuel and the formation of an oil film on the atomizing combustion net 5 to start combustion.

[0029] When the oil is fed: the liquid fuel is directly sprayed into the primary combustion chamber. When the liquid fuel collides with the cyclone generated by the cyclone air inlet 3, it will be dispersed to the surroundings. The small particles of liquid combustion directly adhere to the atomizing combustion net 5 to form an oil film for combustion. The large particles of liquid fuel pass through the atomizing combustion net 5 and spread along the inner wall of the vaporizing combustion tube 2. After high-temperature vaporization, the oil film is formed and burned on the atomizing combustion net 5. Compared with the original annular oil circuit combustion method, this oil feeding and combustion method has a better combustion effect, and the ion combustion body is also easier to process and manufacture.

[0030] The top surface of the base 1 is provided with an annular limiting protrusion for limiting the atomizing combustion net 5, and the annular limiting protrusion can limit the atomizing combustion net 5. The upper end point of the atomizing combustion net 5 is welded to the upper part of the inner wall of the vaporizing combustion tube 2, and the lower end of the atomizing combustion net 5 is located in the annular protrusion 6 and is fixed to the annular protrusion 6 by spot welding.

[0031] The atomizing combustion net 5 is provided with an oil injection port 51 for spraying liquid fuel, and the oil injection port 51 is opened opposite to the oil inlet 12. The opening of the oil injection port 51 can facilitate the liquid fuel to be directly sprayed into the vaporizing combustion chamber.

[0032] The cyclone air inlet cylinder 3 is composed of an air cavity cylinder 31 and an air cavity cover 32, wherein the air cavity cover 32 is welded to the upper end of the air cavity cylinder 31, and the lower end of the air cavity cylinder 31 is integrally formed with the base 1, and an air inlet 11 connected to the inside of the air cavity cylinder 31 is provided at the bottom of the base 1, and a plurality of air outlets are vertically provided around the air cavity cylinder 31, and a spiral cyclone enters from the bottom of the air cavity cylinder 31 and is spirally ejected from the air outlet, driving the liquid fuel in the vaporization combustion chamber to flow, so that it is evenly atomized on the atomization combustion net 5, so as to perform ignition operation through the ignition plug, and the cyclone air inlet cylinder 3 generates a spiral cyclone, utilizing the full vaporization of the liquid fuel in the vaporization combustion chamber.

[0033] An impeller air intake mechanism 4 is provided on the lower bottom surface of the base 1, and the impeller air intake mechanism 4 is composed of a spiral tooth 41 and a spiral tooth cover plate 42. The spiral tooth 41 is integrally formed with the base 1, and the spiral tooth cover plate 42 is welded to the spiral tooth 41. The impeller air intake mechanism 4 is connected with the inside of the cyclone air inlet cylinder 3 through the air inlet 11. Through the structural design of the impeller air intake mechanism 4, when the bottom of the base 1 is blown, air will be sucked in from around the spiral teeth 41, and a cyclone will be formed after passing through the spiral teeth 41, and the air will spiral into the cyclone air inlet cylinder 3 from the air inlet 11, and will be ejected from the air outlets around the cyclone air inlet cylinder 3 to form a cyclone.

[0034] Since the temperature of the outer wall of the second-generation product cannot directly reflect the internal ignition conditions, the utility model can only embed the thermocouple probe. A thermocouple probe mounting hole 35 is opened at the center of the air cavity cover 32 to facilitate the installation of the thermocouple probe. A wire passing hole is opened at the center of the spiral tooth cover plate 42 to facilitate the routing of the thermocouple probe signal line.

[0035] In order to improve the air outlet effect and ensure that the liquid fuel in the upper and lower parts of the vaporization and combustion chamber can be fully vaporized and burned, the air outlet is divided into two types: a high-position air outlet 34 and a low-position air outlet 33. The high-position air outlet 34 and the low-position air outlet 33 are arranged in sequence at intervals. The high-position air outlet 34 is opened at the upper part of the air chamber tube 31, and the low-position air outlet 33 is opened from the upper part of the air chamber tube 31 to the lower part of the air chamber tube 31. The opening of the high-position air outlet 34 can ensure that the liquid fuel in the upper part of the first-level combustion chamber is fully in contact with the air, thereby improving its vaporization and combustion effect.

[0036] The side of the base 1 is provided with an ignition plug mounting hole 14, which is used for mounting the ignition plug and is connected to the oil inlet 12. The oil inlet 12 is arranged along the tangent direction of the vaporization combustion cylinder 2, which is convenient for dispersing the cyclone generated by the cyclone air inlet cylinder 3 and will not be directly sprayed into the cyclone air inlet cylinder 3. The base 1 is provided with a positioning mounting hole 13, which can be used for mounting and fixing the ion combustion body.

[0037] In addition, since the utility model is a second-generation product, a silencer combustion tube with a ceramic silencer is designed on the vaporization combustion tube 2. Secondary and tertiary multi-stage combustion are performed through the silencer combustion tube, and the secondary combustion process no longer requires ion spark dividers. Therefore, the installation structure design for the ion spark dividers is cancelled at the top of the vaporization combustion tube 2 of the present invention.

[0038] The above is a detailed introduction to a liquid fuel ion combustion body provided by the utility model. Specific examples are used in this article to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the method of the utility model and its core idea; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope. Changes and improvements to the utility model will be possible without exceeding the concept and scope specified in the attached claims. In summary, the content of this specification should not be understood as a limitation on the utility model.
