[0002] When metal liquid is refined in a refining furnace, it is often accompanied by harmful precipitates, useless impurities, etc., which affect the quality of the material. In order to obtain better material quality and remove harmful precipitates and useless impurities, oxygen needs to be introduced into the refining furnace to allow the impurities and precipitates to be fully oxidized to generate useful metal materials. The useless substances that cannot react are blown away by oxygen, so that the metal liquid can be layered due to different density and weight.

[0025] A plurality of oxygen outlets 110 are provided on the side of the first end (oxygen outlet end) of the oxygenation tube module 100, and an oxygen inlet 120 is provided at the port of the second end of the oxygenation tube module 100; a connection unit 130 is provided in the middle of the oxygenation tube module 100, and the connection unit 130 includes a first connection step 131 and a second connection step 132, the first connection step 131 is provided with a buckle loading and unloading port 133, a rotation slot 134 is provided between the first connection step 131 and the second connection step 132, and a blocking block 135 is installed in the rotation slot 134;

[0026] The baffle module 200 is sleeved between the first end of the oxygenation tube module 100 and the connecting unit 130, a baffle 210 is provided on the side of the baffle module 200 and the oxygen outlet direction of the oxygen outlet 110 is toward the baffle 210, one end of the baffle module 200 (close to the first end of the oxygenation tube module) is provided with a first diffusion oxygen outlet area 220, and the side of the baffle module 200 is provided with a second diffusion oxygen outlet area 230 and a third diffusion oxygen outlet area 240, the other end of the baffle module 200 (close to the connecting unit) is provided with a buckle 250, the buckle 250 is installed in the rotating slot 134 through the buckle loading and unloading port 133, and one end of the buckle 250 is against the blocking block 135.

[0027] Specifically, the port at the first end of the oxygenation pipe module 100 is provided with an end cap 140 (the port at the first end is not conductive so that the oxygen entering from the oxygen inlet can be discharged from the oxygen outlet located at the side).

[0028] More specifically, a fixing flange 150 is installed on the side of the second end of the oxygenation tube module 100 .

[0029] Furthermore, the buckle includes a first buckle, a second buckle and a third buckle, the buckle loading and unloading port includes a first buckle loading and unloading port, a second buckle loading and unloading port and a third buckle loading and unloading port, and the blocking block includes a first blocking block, a second blocking block and a third blocking block, wherein:

[0030] The first buckle is installed in the rotating slot through a first buckle installation and removal port, and one end of the first buckle abuts against the first blocking block;

[0031] The second buckle is installed in the rotating slot through the second buckle installation and removal port, and one end of the second buckle abuts against the second blocking block;

[0033] Furthermore, the oxygen inlet 120 is connected to the oxygen supply equipment through the fixing flange 150 .

[0034] For this utility model:

[0035] The interior of the refining oxygenation tube is a hollow tube, one end of the tube is blocked (i.e. the first end of the oxygenation tube module), and three oxygen outlets with the same angle are opened on the side circumference (such as Figure 2As shown in the figure, when the oxygen is supplied from the oxygen supply equipment to the oxygen inlet of the oxygen adding pipe module, the oxygen passes through the hollow tube and comes out from the three oxygen outlets. Due to the high-speed oxygen, it encounters the rebound of the circular baffle installed outside, and the oxygen changes its flow direction. From the three diffusion oxygen outlet zones of the circular baffle, the oxygen is evenly transported to the molten metal in the refining furnace.

[0036] Due to the long-term continuous erosion of high-speed oxygen, the cylindrical part of the circular shield is severely corroded and often needs to be replaced. Therefore, three buckles are designed ( Figure 3 The middle part of the oxygenation tube module is designed with a connection step, a rotation slot, and a buckle loading and unloading port ( Figure 2 shown), from Figure 1 It can be seen that when this accessory is severely corroded, it is very convenient to replace it. When the circular shielding plate is rotated to the right to the buckle loading and unloading port, it can be easily removed along the axial direction by pulling it hard toward the oxygen outlet. When installing, align the buckle of the circular shielding plate with the buckle loading and unloading port and push it in. When it touches the second connection step, rotate it to the left at the same time until it stops when it touches the blocking block. At this time, it is very convenient to successfully connect the shielding plate module. It is easy to disassemble and reduce the maintenance and replacement time. In addition, 3 buckles, 3 buckle loading and unloading ports and 3 blocking blocks are set to improve the stability of the overall structure.
