[0002] Traditional liquid fuel combustion burners (see appendix) Figure 3 It uses a high-pressure spray method for fuel supply, which is noisy. Moreover, due to the rapid injection of fuel, the mixing degree with air is limited, resulting in incomplete combustion and high energy consumption. In addition, its igniter lacks cooling and is continuously exposed to the flame, resulting in a short service life. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an internally burned liquid fuel combustion burner head to solve the technical problems in the background art mentioned above.

[0004] The technical solution of this utility model is as follows:

[0005] An internally burned liquid fuel combustion burner includes a combustion chamber, an oxygen supply chamber, an igniter, an oxygen supply fan, a liquid fuel tank, and an oil pump. The oxygen supply chamber surrounds the peripheral and bottom walls of the combustion chamber. The igniter is installed at the bottom of the combustion chamber, and a flame stabilizing ring is installed on the lower part of the peripheral wall of the combustion chamber near the igniter. Several layers of air inlets are formed in the peripheral wall of the combustion chamber above the flame stabilizing ring, and a high-temperature mesh cover assembly is installed on the top of the combustion chamber. The bottom of the oxygen supply chamber is connected to the oxygen supply fan through an air inlet pipe. The liquid fuel tank is horizontally connected to the upper side of the igniter inside the combustion chamber through an oil inlet pipe connected in series with the oil pump. The outlet is close to the igniter and is lower than the flame stabilizing ring.

[0006] Furthermore, a downward-sloping air inlet baffle is installed above the outlet of the air inlet duct in the oxygen supply room.

[0007] Furthermore, the diameter of the air intake is 0.1-3.6mm.

[0008] Furthermore, the high-temperature mesh cover assembly includes a high-temperature mesh, an upper fixing ring, a lower fixing ring, and a fastener. The high-temperature mesh is sandwiched between the upper fixing ring and the lower fixing ring, and the top of the fastener is fitted over the outer edge of the high-temperature mesh, the upper fixing ring, and the lower fixing ring, and welded together to form a whole.

Detailed Implementation

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] like Figure 1-2 As shown:

[0019] An internally burned liquid fuel combustion burner includes a combustion chamber 2, an oxygen supply chamber 1, an igniter, an oxygen supply fan 5, a liquid fuel tank 4, and an oil pump 41. The oxygen supply chamber 1 is arranged around the peripheral wall and bottom wall of the combustion chamber 2. The igniter is installed at the bottom of the combustion chamber 2, and a flame stabilizing ring 22 is installed on the lower part of the peripheral wall of the combustion chamber 2 near the igniter. Several layers of air inlets 21 are opened on the peripheral wall of the combustion chamber 2 above the flame stabilizing ring 22. A high-temperature mesh cover assembly 3 is installed on the top of the combustion chamber 2. The bottom side of the oxygen supply chamber 1 is connected to the oxygen supply fan 5 through an air inlet pipe 51. The liquid fuel tank 4 is horizontally connected to the upper side of the igniter in the combustion chamber 2 through an oil inlet pipe 42 connected in series with the oil pump 41. The outlet is close to the igniter and is lower than the flame stabilizing ring 22.

[0020] In this invention, liquid fuel enters the combustion chamber 2 at low pressure and flows directly onto the igniter. This fuel injection method allows for rapid ignition, and the liquid fuel can simultaneously cool the igniter, extending its service life. The design of the high-temperature mesh cover assembly 3 allows the flame in the combustion chamber 2 to form a high-temperature, soft combustion under the action of the high-temperature mesh cover assembly 3. Moreover, the heat and flame can be quickly dispersed under the action of the high-temperature mesh cover assembly 3, thereby forming a more uniform heat field. Compared with the traditional high-pressure electric spray combustion mode, the combustion is more complete and energy-saving, while the flame is softer and more stable.

[0021] As an optimized solution, an inclined air inlet baffle 511 is installed above the outlet of the air inlet pipe 51 inside the oxygen supply chamber 1. The air inlet baffle 511 can press down the airflow and quickly form turbulence, thereby allowing the airflow to be quickly dispersed into the oxygen supply chamber 1 and improving the uniformity of oxygen supply.

[0022] As an optimized solution, the diameter of the air inlet 21 is 0.1-3.6mm. The design size of this hole makes the oxygen supply to the liquid fuel more uniform and gentle, allowing the liquid fuel to be completely vaporized and burned in the combustion chamber 2.

[0023] To facilitate disassembly and assembly, the high-temperature mesh cover assembly 3 includes a high-temperature mesh 31, an upper fixing ring 32, a lower fixing ring 33, and a fastener 34. The high-temperature mesh 31 is sandwiched between the upper fixing ring 32 and the lower fixing ring 33. The top of the fastener 34 is fitted over the outer edges of the high-temperature mesh, the upper fixing ring 32, and the lower fixing ring 33, and they are welded together as a whole. The inner diameter of the upper fixing ring 32 and the lower fixing ring 33 is equal to the inner diameter of the combustion chamber 2, and the inner diameter of the fastener 34 is equal to the outer diameter of the oxygen supply chamber 1. This allows the entire assembly to be directly removed or installed without damaging the high-temperature mesh.

[0024] Meanwhile, a screw sleeve is installed from the bottom of the combustion chamber 2 to the bottom of the oxygen supply chamber 1. The igniter enters the combustion chamber 2 through the screw sleeve from the bottom of the oxygen supply chamber 1 via a threaded connection. This facilitates the replacement and installation of the igniter later.

[0025] A flange 11 is welded to the middle of the outer wall of the oxygen supply chamber 1 to facilitate fixing it to the furnace body.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
