[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0023] Example 1: A fuel atomizing gun for a burner, such as Figure 1-Figure 4 As shown, it includes a supporting shell 1 and a limiting screen 4 installed inside the supporting shell 1, a plurality of filter holes 11 are penetrated on the limiting screen 4, a rotating fan blade 8 is rotatably provided inside the limiting screen 4, a limiting hole 9 is penetrated on the rotating fan blade 8, a secondary rotating fan 10 is provided below the rotating fan blade 8, and the secondary rotating fan 10 is connected to the rotating fan blade 8 in the same manner, a rotating shaft 7 is installed in the middle of the rotating fan blade 8 and the secondary rotating fan 10, a rotating motor 6 is installed on the upper end of the rotating shaft 7, the rotating shaft 7 is installed at the output end of the rotating motor 6, a circulation support head 12 is installed on the end of the rotating shaft 7 away from the rotating motor 6, and the circulation support head 12 is located inside the supporting shell 1.

[0024] When the device is in use, the burning raw materials flow out from the inside of the limiting screen 4 under the guidance of the supporting shell 1, and then flow to the side of the secondary rotating fan 10. Under the driving support of the rotating motor 6 and the transmission support of the rotating shaft 7, the rotating fan blades 8 and the secondary rotating fan 10 are driven to rotate simultaneously, so that the raw materials can be cut and separated under the rotation of the rotating fan blades 8 and the secondary rotating fan 10 themselves to reduce their specifications. Then, under the limiting guidance of the upper and lower layers of multiple limiting holes 9, the flowing raw materials are limited to ensure the stability of their flow direction and channel, while improving the efficiency of raw material splitting. At the same time, under the flow limiting support of the multiple filter holes 11 on the limiting screen 4, the sufficient limited circulation of the raw materials is guaranteed. Finally, under the guidance of the circulation support head 12, the raw materials are limited and discharged, so that under the support of multiple layers of limiting guides, the specifications of the circulating liquid in the supporting shell 1 are fully and efficiently reduced, thereby improving the accuracy and efficiency of the device in atomizing the raw materials.

[0025] like Figure 1-Figure 4 As shown, a sealing support block 3 is installed inside the supporting shell 1 , and a rotating motor 6 is installed in the middle of the sealing support block 3 .

[0026] The rotating shaft 7 is rotatably mounted on the middle of the sealing support block 3 , and the rotating shaft 7 is rotatably mounted on the middle of one end of the circulation support head 12 .

[0027] Under the limiting support of the sealing support block 3, the accurate position of the rotating motor 6 and the rotating shaft 7 during operation is guaranteed. At the same time, under the rotation support of the circulation support head 12 and the sealing support block 3 on the rotating shaft 7, the accuracy of its axial movement during rotation is improved, and the rotation angle deviation is effectively prevented.

[0028] Example 2: A fuel atomizing gun for a burner, such as Figure 1-Figure 4 As shown, the rotating blades 8 and the secondary rotating fan 10 rotate in the same direction, and the rotating blades 8 are located inside the limiting screen 4, and the secondary rotating fan 10 is located below the limiting screen 4.

[0029] By arranging the rotating fan blades 8 inside the limiting screen 4, the raw materials that have been initially separated by limiting can be processed inside the limiting screen 4, and then under the limiting guidance of the filter holes 11 on the sides of the limiting screen 4, the adequacy of the secondary isolation and guidance of the raw materials is guaranteed. Finally, the raw materials are again limited in flow through the secondary rotating fan 10, thereby improving the efficiency of the atomization and mixing of the raw materials inside the device on the basis of the original multiple limiting operations, thereby improving the efficiency of its combustion.

[0030] like Figure 1-Figure 4 As shown, a rotating support ring 5 is installed on the outside of the limiting screen 4, and the rotating support ring 5 is rotatably installed inside the supporting shell 1.

[0031] Under the position-limiting support of the supporting shell 1 on the rotating supporting ring 5, it is ensured that the position-limiting screen 4 and the rotating supporting ring 5 can be positioned while rotating inside the supporting shell 1, thereby improving the various modes of their operation.

[0032] A feed pipe 2 is inserted into the outer end of the sealing support block 3 , and the feed pipe 2 extends to the other end of the sealing support block 3 . There are at least two feed pipes 2 , and the two feed pipes 2 are used for the circulation of different materials.

[0033] By sealing the sealing support block 3 and guiding the feed pipe 2, the external raw materials can flow directly into the support shell 1 through the feed pipe 2, thereby improving the sealing of the mixing and circulation, and improving the stability and safety of the device during use.

[0034] Working principle: First, the burning raw materials flow out from the inside of the limiting screen 4 under the guidance of the supporting shell 1, and then flow to the side of the secondary rotating fan 10. Under the driving support of the rotating motor 6 and the transmission support of the rotating shaft 7, the rotating fan blades 8 and the secondary rotating fan 10 are driven to rotate simultaneously, so that under the rotation of the rotating fan blades 8 and the secondary rotating fan 10 themselves, the raw materials can be cut and separated to reduce their specifications. Then, under the limiting guidance of the upper and lower layers of multiple limiting holes 9, the flowing raw materials are limited to ensure the stability of their flow direction and channel, while improving the efficiency of raw material splitting. At the same time, under the flow limiting support of the multiple filter holes 11 on the limiting screen 4, the sufficient limited circulation of the raw materials is guaranteed. Finally, under the guidance of the circulation support head 12, the raw materials are limited and discharged, so that under the support of multiple layers of limiting guides, the specifications of the circulating liquid inside the supporting shell 1 are fully and efficiently reduced, thereby improving the accuracy and efficiency of the device in atomizing raw materials.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
