[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Please see Figures 1-4 The present invention provides the following technical solution:

[0027] An all-oxygen AOD baking burner nozzle, comprising:

[0028] Burner nozzle 1;

[0029] Air intake volume regulating groove 2 is located inside the burner nozzle 1;

[0030] Gas regulating pipe 3 is fixedly connected to the inner circumferential wall of the air intake regulating groove 2. Gas regulating pipe 3 is made of hard rubber material.

[0031] Adjusting turntable 4 is rotatably connected to the upper inner wall of the air intake volume adjustment groove 2;

[0032] The flaring mechanism has multiple sets. These multiple flaring mechanisms control the flame spray distance by controlling the air intake of the gas regulating pipe 3. Each flaring mechanism includes a circular concentric contraction block 5, a pull rod 6, an upper pull block 7, an upper rotating groove 8, a lower rotating rod 9, and a lower fixed groove 10. The lower fixed groove 10 is fixedly connected to the lower inner wall of the air intake regulating groove 2. The circular concentric contraction block 5 is located in the air intake regulating groove 2. The lower rotating rod 9 is located at the lower end of the circular concentric contraction block 5. The lower fixed groove 10 is rotatably connected to the lower rotating rod 9. The upper rotating groove 8 is located at the upper end of the circular concentric contraction block 5. The pull rod 6 is rotatably connected to the lower end of the regulating turntable 4 via a rotating shaft. The upper pull block 7 is fixedly connected to the lower end of the pull rod 6 and rotates within the upper rotating groove 8.

[0033] In a specific embodiment of this utility model, the air intake regulating groove 2 is disposed inside the burner nozzle 1 to adjust the amount of air entering the burner. The gas regulating pipe 3 is used to control the amount of gas entering the burner. The gas regulating pipe 3 is made of hard rubber material to ensure durability while providing necessary flexibility. The regulating turntable 4 adjusts the mixing ratio of gas and air by rotating, thereby affecting the flame characteristics. Multiple circular concentric contraction blocks 5 fit together. When the regulating turntable 4 is rotated, the lower side of the circular concentric contraction block 5 is fixed by the lower rotating rod 9 and the lower fixing groove 10, while the upper end is pulled by the upper pulling block 7 and the pulling rod 6, so that the circular concentric contraction block 5 rotates with the lower rotating rod 9 as the axis. The center of the multiple circular concentric contraction blocks 5 forms a circular expansion and contraction, and squeezes the gas regulating pipe 3 disposed in the middle of the multiple circular concentric contraction blocks 5, thereby adjusting the gas intake amount, so as to expand or shrink the outlet area of ​​the burner nozzle 1 as needed, thereby achieving the purpose of controlling the flame injection distance.

[0034] Please refer to the details. Figures 1-4 A combustion nozzle 11 is fixedly connected to the lower end of the gas regulating pipe 3, and the combustion nozzle 11 is located at the lower end of the burner nozzle 1.

[0035] In this embodiment, the function of the combustion nozzle 11 is to guide the mixture of gas and air to the outlet and ignite it. Since the combustion nozzle 11 is located at the lower end of the burner nozzle 1, its position and structural design can ensure that the flame is stably ejected from the nozzle, while avoiding backfire.

[0036] Please refer to the details. Figures 1-4 Multiple circular concentric contraction blocks 5 are all arc-shaped, and multiple circular concentric contraction blocks 5 fit together on one side of each other when rotating.

[0037] In this embodiment: In the initial state, multiple circular concentric contraction blocks 5 are in the fully extended position, the outlet area of ​​the burner nozzle 1 is the largest, and the flame jet distance is the farthest. Conversely, when it is necessary to increase the flame jet distance, the adjusting turntable 4 rotates counterclockwise, and the circular concentric contraction blocks 5 expand outward, increasing the gas intake of the burner nozzle 1.

[0038] Please refer to the details. Figures 1-4 An adjustment groove 13 is provided on the upper inner wall of the air intake adjustment groove 2, and an adjustment rod 14 is fixedly connected to the upper end of the adjustment turntable 4. The adjustment rod 14 rotates in the adjustment groove 13.

[0039] In this embodiment: when the user rotates the adjustment dial 4, the adjustment rod 14 moves along the adjustment groove 13. This mechanical linkage mechanism drives the change of gas flow in the gas regulating pipe 3 and the position adjustment of the circular concentric contraction block 5. The adjustment groove 13 restricts the range of motion of the adjustment rod 14, which indirectly limits the maximum rotation angle of the adjustment dial 4.

[0040] Please refer to the details. Figures 1-4 The upper end of the burner nozzle 1 is fixedly connected to a gas inlet pipe 15, which is connected to the upper end of the gas regulating pipe 3. A fixing flange 12 is fixedly connected to the circumferential surface of the burner nozzle 1.

[0041] In this embodiment: the gas enters the gas regulating pipe 3 through the gas inlet pipe 15, and the flow rate is adjusted according to the operation of the regulating turntable 4, and finally reaches the combustion nozzle 11 for combustion. The fixed flange 12 securely installs the burner nozzle 1 to the external equipment by bolts or other fixing methods to prevent loosening caused by vibration or external force.

[0042] The working principle and usage process of this utility model are as follows: The air intake regulating groove 2 is set inside the burner nozzle 1 to adjust the amount of air entering the burner. The gas regulating pipe 3 is used to control the amount of gas entering the burner. The gas regulating pipe 3 is made of hard rubber material, which ensures durability while providing necessary flexibility. The regulating turntable 4 adjusts the mixing ratio of gas and air by rotating, thereby affecting the flame characteristics. Multiple circular concentric contraction blocks 5 fit together. When the regulating turntable 4 is rotated, the lower side of the circular concentric contraction block 5 is fixed by the lower rotating rod 9 and the lower fixing groove 10, while the upper end is pulled by the upper pulling block 7 and the pulling rod 6, so that the circular concentric contraction block 5 rotates with the lower rotating rod 9 as the axis. The center of the multiple circular concentric contraction blocks 5 forms a circular expansion and contraction, and squeezes the gas regulating pipe 3 set in the middle of the multiple circular concentric contraction blocks 5, thereby adjusting the gas intake amount, so as to expand or shrink the outlet area of ​​the burner nozzle 1 as needed, thereby achieving the purpose of controlling the flame spray distance.

[0043] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
