[0002] The ignition device is the core component of the burner. As a tool for the burner to generate flames, it generally generates a high-frequency ignition arc by discharging an ignition electrode to the ground, and then establishes a pilot fire. Its reliability and stability are the guarantee for the burner to establish the main combustion flame. However, the existing ignition burners are prone to uneven combustion and incomplete combustion during the gas combustion process, which not only leads to fuel waste but also easily leads to the increase of harmful substances, thereby polluting the environment. In addition, the fuel gas is sprayed out through the gas nozzle and mixed with the surrounding air. After the ignition electrode discharges to the nozzle, the arc ignites the mixed gas. Due to the lack of a flame stabilizing device, the ignition flame is unstable and easily extinguished. Summary of the invention

[0006] The two sides of the connecting pipe are inlaid with conveying pipe groups, and one end of the conveying pipe group is inlaid and connected with the two sides of the spiral pipe, while the other end of the conveying pipe group is movably installed with a connecting threaded cap.

[0007] By adopting the above technical solution, a threaded installation connection is achieved by providing a connecting threaded cap.

[0008] Preferably, a Yuanbao shield with a hollow structure inside is inlaid and installed on the connecting pipe, and a spiral tube extends inside the Yuanbao shield, and cavity tube groups are inlaid and installed on both sides of the bottom of the Yuanbao shield.

[0009] By adopting the above technical solution, the ingot shield is provided to achieve inlay installation.

[0010] Preferably, a spiral frame is fixed inside the cavity tube group through the mounting frame, and the spiral frame is fixedly installed in a symmetrical manner.

[0011] By adopting the above technical solution, the spiral frame is provided to achieve spiral conveying.

[0012] Preferably, the gas delivery structure comprises a connecting ring with a hollow structure inside, and a hollow T-shaped tube is inlaid and installed on the connecting ring, and air holes are opened through the surface of the hollow T-shaped tube.

[0021] By adopting the above technical solution, the hollow T-shaped tube is provided to achieve the function of embedding installation connection and penetrating opening setting.

[0022] Preferably, the overall cross-sectional area of ​​the connection cover is arranged in an "L" structure.

[0023] By adopting the above technical solution, the connecting cover is provided to achieve a wrapping installation setting.

[0024] Compared with the prior art, the invention has the following beneficial effects: the self-stabilizing ignition burner with a countercurrent injection structure,

[0025] (1) This case sets up: the tube structure, so as to solve the problem that the existing ignition burner is prone to uneven combustion and incomplete combustion during the gas combustion process, which not only leads to fuel waste but also easily leads to the increase of harmful substances, thereby polluting the environment. When the gas is transported inside the spiral tube, it drives the stirring blade to rotate to mix the gas. The mixed gas is transported inside the Yuanbao shield and collides with the inner wall of the Yuanbao shield. When the mixed gas collides with the inside of the Yuanbao shield, it is refracted. After refraction, a reverse airflow is formed and transported inside the cavity tube group for dispersed transportation. The refracted gas can achieve uniform combustion and flame stability;

[0026] (2) By stabilizing the harm reduction structure, the connection sleeve is provided to solve the problem that the gas is sprayed through the gas nozzle and mixed with the surrounding air. After the ignition electrode discharges to the nozzle, the arc ignites the mixed gas. Due to the lack of a flame stabilizing device, the ignition flame is unstable and easily extinguished. When the ignition electrode is working, the connection sleeve wraps and protects the ignition electrode. When the connection sleeve wraps and protects the ignition electrode, external factors can be avoided to prevent the ignition electrode from being unstable;

[0027] (2) The above-mentioned problem is solved by stabilizing the harm reduction structure by providing: a connection cover, a guide groove and cooling water. When the gas is burning, the flame contacts the connection cover. When the flame contacts the connection cover, the cooling water absorbs heat. Even if the flame is directly sprayed onto the connection cover, the connection cover will not burn. At the same time, since the cooling water in the connection cover absorbs heat, the flame temperature is reduced and the emission of harmful substances is also reduced.

[0028] (4) By setting up a gas delivery structure, the problem of being unable to ignite in time when a single ignition electrode is damaged is solved. When multiple ignition electrodes are operating synchronously, multiple released mixed gases are ignited. By igniting multiple mixed gases at the same time, not only can the waste of gas diffusion be avoided, but also the problem of being unable to ignite quickly when a single ignition electrode is damaged can be avoided.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-7 The present invention provides a technical solution: a self-stable ignition burner with a countercurrent injection structure, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a tube body structure 1, which includes a spiral tube 101 with a bearing seat 102 inside, and a stirring blade 104 is installed between the bearing seat 102 through a connecting shaft 103. At the same time, the spiral tube 101 is fixed to the connecting tube 105 through a mounting plate, wherein a plurality of stirring blades 104 are provided, and the gas transported inside the spiral tube 101 is mixed and stirred by utilizing the plurality of stirring blades to form a mixed gas, and then transported and ignited.

[0039] In the above scheme, the two sides of the connecting pipe 105 are embedded with a conveying pipe group 106, and one end of the conveying pipe group 106 is embedded and connected with the two sides of the spiral tube 101, and the other end of the conveying pipe group 106 is movably installed with a connecting threaded cap 107.

[0040] Furthermore, in the above solution, a Yuanbao shield 108 with a hollow structure inside is inlaid on the connecting tube 105, and a spiral tube 101 extends inside the Yuanbao shield 108. At the same time, cavity tube groups 109 are inlaid on both sides of the bottom of the Yuanbao shield 108.

[0041] In the above solution, a spiral frame 1011 is fixed inside the cavity tube group 109 through the mounting frame 1010, and the spiral frame 1011 is fixedly installed in a symmetrical manner.

[0042] like Figure 5 As shown, a gas delivery structure 2 is installed directly above the tube body structure 1, and the gas delivery structure 2 includes a connecting ring 201 with a hollow structure inside, and a hollow T-shaped tube 202 is inlaid and installed on the connecting ring 201, and a vent hole 203 is opened through the surface of the hollow T-shaped tube 202. There are 8 hollow T-shaped tubes 202, and the hollow T-shaped tubes 202 are arranged in a ring array about the connecting ring 201. When there are 8 of the above-mentioned components, it not only reflects the practicality of the installation and arrangement of the above-mentioned components, but also reflects the openness and synchronous transportation of the installation and arrangement of the above-mentioned components. When there are 8 of the above-mentioned components, it not only reflects the installability of the above-mentioned components, but also reflects the equidistant distribution of the above-mentioned components. When there are 8 of the above-mentioned components, the symmetry of the installation and arrangement of the above-mentioned components is reflected, and the axial and axial axis symmetric installation of the above-mentioned components is also reflected simultaneously.

[0043] Furthermore, in the above scheme, a connecting frame 204 is fixed on the inner side of the connecting ring 201, and an ignition electrode 205 is fixed on the connecting frame 204, and the ignition electrode 205 is installed and connected to the electrode fixing seat 206 through the connecting frame 204, wherein the number of ignition electrodes 205 is installed and set synchronously with the number of hollow T-shaped tubes 202, and when the above-mentioned parts are installed and set with the same number, it effectively achieves the effect of synchronous and practical installation and setting.

[0044] like Figure 6 and Figure 7 As shown, a stable harm reduction structure 3 is installed on the gas delivery structure 2, and the stable harm reduction structure 3 includes a connecting cover 301 with an internal hollow structure, and a guide groove 302 is opened on the inner side of the connecting cover 301, and cooling water 303 is injected into the connecting cover 301. The overall cross-sectional area of ​​the connecting cover 301 is arranged in an "L" structure. When the cross-sectional area of ​​the above-mentioned parts is arranged in an "L" structure, it can be clearly known that the overall shape of the above-mentioned parts is arranged in a trumpet structure. When the overall shape of the above-mentioned parts is arranged in a trumpet structure, it is effectively convenient for the diffusion combustion of the flame, and it is also effectively convenient for the vertical delivery and vertical ignition and combustion of the airflow. When the cross-sectional area of ​​the above-mentioned parts is arranged in an "L" structure, it reflects the practicality of the installation setting of the above-mentioned parts, and also reflects the wrapping and installation properties of the above-mentioned parts.

[0045] Furthermore, in the above scheme, a connecting sleeve 304 is embedded and installed on one side of the connecting cover 301, and the connecting sleeve 304 is installed and wrapped around the ignition electrode 205, wherein the number of connecting sleeves 304 and connecting covers 301 are installed and arranged in the same number as the number of ignition electrodes 205, and when the above two are installed and arranged in the same number as the ignition electrodes 205, an effective same-number matching installation effect is achieved.

[0046] In the above scheme, after the gas is transported inside the spiral tube 101, it drives the stirring blade 104 to rotate, thereby mixing the gas. After the mixed gas is transported inside the Yuanbao shield 108, it collides with the inner wall of the Yuanbao shield 108. When the mixed gas collides with the inside of the Yuanbao shield 108, it is refracted and transported to the connecting ring 201. The mixed gas transported inside the connecting ring 201 diffuses into the inside of the connecting cover 301 through the hollow T-shaped tube 202 and the air hole 203. At this time, the ignition electrode 205 ignites the gas inside the connecting cover 301. During the combustion process, the cooling water 303 carries away part of the flame heat to prevent the diffusion of harmful substances.
