Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Referring to Figure 1 , an embodiment provided by the present utility model: an adjustable three - sleeve branch mixer includes a connecting rod 7. A pure oxygen passage 4 is sleeved outside the connecting rod 7, and a first sealing connection assembly is arranged outside the pure oxygen passage 4. A mixing passage 5 is sleeved outside the connecting rod 7, and a second sealing connection assembly is arranged outside the mixing passage 5. A gas passage 6 is sleeved outside the connecting rod 7, and a third sealing connection assembly is arranged outside the gas passage 6. A fluid passage changing device 8 is fixedly connected to the right side of the connecting rod 7. One end of the right side of the mixing passage 5 is fixedly connected to a tapered nozzle 9. A sealing rubber ring 12 is arranged between the connecting rod 7 and the pure oxygen passage 4, and a support member 13 is fixedly connected to the outside of the connecting rod 7.

[0029] Specifically, the pure oxygen channel 4 is a pipeline for transporting pure oxygen, the mixing channel 5 is a pipeline for transporting air or gas, and the gas channel 6 is a pipeline for transporting gas. They are respectively responsible for introducing different gases into the mixer. The connecting rod 7 passes through the tapered nozzle 9 and the support 13 from left to right in sequence, and the mechanical structure of the connecting rod 7 for adjusting the branch pipe opening is connected to the branch pipe. By adjusting the position of the connecting rod 7, the opening of the branch pipe can be changed, thereby adjusting the flow rate of each gas. The fluid path changing device 8 is used to adjust the fluid path in the mixer. The tapered nozzle 9 is used to accelerate the fluid flow rate for better mixing. Through the tapered design, the nozzle can increase the gas velocity. The sealing rubber ring 12 ensures that there is no gas leakage at the pure oxygen channel 9 during the left and right movement of the connecting rod 7. The support 13 provides structural support for the mixer to ensure the stability of the mixer during operation. The support 13 helps to maintain the relative positions of the various components to ensure the normal operation of the mixer.

The second sealing connection assembly includes the second docking flange 2, the first sealing flange plate 10 and the second sealing flange plate 11. The second docking flange 2 is externally fixedly connected to the top of the second docking flange 2. The other first sealing flange plate 10 is externally fixedly connected to the left side of the outside of the mixing channel 5. One of the second sealing flange plates 11 is externally fixedly connected to the right side of the outside of the mixing channel 5. The third sealing connection assembly includes the third docking flange 3 and the second sealing flange plate 11. The third docking flange 3 is externally fixedly connected to the top of the gas channel 6. The other second sealing flange plate 11 is externally fixedly connected to the left side of the outside of the gas channel 6.

[0031] Specifically, the first docking flange 1, the second docking flange 2 and the third docking flange 3 are used to connect the mixer to other systems or devices. They provide a stable connection and ensure the sealing between the mixer and other components. The first docking flange 1 is used for the connection of the pure oxygen channel 4 of the equipment to the external pure oxygen process pipeline. The second docking flange 2 is used for the connection of the mixing channel 5 of the equipment to the external air or gas process pipeline. The third docking flange 3 is used for the connection of the gas channel 6 of the equipment to the external gas process pipeline. The first sealing flange plate 10 and the second sealing flange plate 11 are responsible for ensuring good sealing at each connection point of the mixer to prevent gas leakage and maintain the stability of the system.

[0032] Referring to Figure 1, an asbestos gasket is provided between two sealing flange plates 10, and an asbestos gasket is provided between two sealing flange plates 11. The support member 13 is fixedly connected to the inside of the pure oxygen channel 4. The fluid path changing device 8 is of a conical structure and its outer surface needs to be polished to ensure that the outer surface is flat and smooth. The pure oxygen channel 4 is made of seamless stainless steel pipe, and the mixing channel 5 and the gas channel 6 are made of seamless carbon steel pipe. The butt joint flange 1 and the sealing flange plate 10 are made of stainless steel, and the butt joint flange 2, the sealing flange plate 11 and the butt joint flange 3 are made of carbon steel. A sealing flange plate 14 is provided between the pure oxygen channel 4 and the connecting rod 7.

[0033] Specifically, the connection method between the butt joint flange 1 and the pure oxygen channel 4 is welding, the connection method between the butt joint flange 2 and the mixing channel 5 is welding, the connection method between the butt joint flange 3 and the gas channel 6 is welding, the connection method of the part where the connecting rod 7 is connected to the fluid path changing device 8 is welding, the connection method between the tapered nozzle 9 and the mixing channel 5 is welding, the connection method of the left flange of the sealing flange plate 10 and the pure oxygen channel 4 is welding, the connection method of the right flange of the sealing flange plate 10 and the mixing channel 5 is welding, and the flanges are fastened with bolts. The connection method of the left flange of the sealing flange plate 11 and the mixing channel 5 is welding, the connection method of the right flange of the sealing flange plate 11 and the gas channel 6 is welding, and the flanges are fastened with bolts. The support member 13 is the support of the connecting rod 7 inside the pure oxygen channel 4. There are 3 contact points between the support member 13 and the inner wall of the pure oxygen channel 4, and the 3 contact points are arranged at an angle of 120° to each other along the inner wall of the pure oxygen channel 4. The contact points of the support member 13 are firmly welded to the inner wall of the pure oxygen channel 4 and ensure that the support member 13 and the connecting rod 7 are concentric. The sealing rubber ring 12 is installed between two sealing flange plates 14, so as to ensure the sealing between the pure oxygen channel 4 and the connecting rod 7.

[0034] Working principle: Pure oxygen enters the pure oxygen channel 4 through the butt joint flange 1, and gas enters the mixing channel 5 and the gas channel 6 through the butt joint flange 2 and the butt joint flange 3 respectively. The gas flow in the mixing channel 5 passes through the tapered nozzle 9, and the gas flow rate increases under the action of the nozzle. The accelerated gas is fully mixed with the gas ejected from the gas channel 6 and the pure oxygen ejected from the pure oxygen channel 4 and then burns. The dimension of the connecting rod 7 exposed outside the tapered nozzle 9 is denoted as ΔL, and the annular fluid channel area between the fluid path changing device 8 and the tapered nozzle 9 is denoted as ΔS. In the above process, by adjusting ΔL, the horizontal position of the fluid path changing device 8 can be changed. During the process of the fluid path changing device 8 moving left and right along the horizontal direction, ΔS is constantly changing, and the fluid flow rate V flowing through the annular fluid channel between the fluid path changing device 8 and the tapered nozzle 9 is also constantly changing. When ΔL gradually decreases, ΔS becomes smaller and V becomes faster. On the contrary, when ΔL gradually increases, ΔS becomes larger and V becomes slower. An automatic adjusting device for ΔL can be connected to the left side of the connecting rod 7 to realize the real-time continuous automatic adjustment of ΔS and V.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
