[0002] A bottom-blown furnace is an industrial device used for smelting metals, particularly steel and non-ferrous metals. It promotes the smelting reaction by injecting oxygen or other gases from the bottom. Compared to a traditional top-blown furnace, the airflow direction in a bottom-blown furnace is upward from the bottom, rather than downward from the top. This design has unique advantages, especially in handling blast furnace charge, removing impurities, and improving reaction efficiency. The silver content in the oxidative smelting material in a bottom-blown furnace is mainly adjusted by controlling the oxygen dosage during the smelting process, thereby optimizing silver recovery and ensuring stable silver content in the product.

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.

[0024] Example 1

[0025] Please see Figure 1-5 As shown, a device for adjusting the silver content of materials in bottom-blown furnace oxidation smelting includes an oxygen supply pipe 2, and a flange 1 is fixedly connected to the left end of the outer surface of the oxygen supply pipe 2.

[0026] An adjustment component is provided on the outer surface of the oxygen supply pipe 2. A groove 6 is provided on the left side of the oxygen supply pipe 2. An installation component 7 is provided inside the groove 6 and the inside of the oxygen supply pipe 2. An installation ring 8 is installed inside the oxygen supply pipe 2 through the installation component 7. A filter screen 9 is fixedly connected inside the installation ring 8. During operation, one end of the oxygen supply pipe 2 is fixedly installed to the external oxygen supply equipment through the flange 1, and the other end of the oxygen supply pipe 2 is fixedly installed to the nozzle at the bottom of the bottom blowing furnace. Oxygen from the oxygen supply pipe 2 is introduced into the bottom blowing furnace through the nozzle for oxidation reaction. The adjustment component can be used to adjust the oxygen supply pipe 2. The amount of oxygen introduced into the bottom-blown furnace is regulated, thereby controlling the oxygen addition ratio during the smelting process to adjust the silver content of the oxidized smelting material in the bottom-blown furnace. At the same time, the oxygen supply pipe 2 is filtered by the mounting ring 8 and filter screen 9 installed through the mounting component 7, which ensures the quality of oxygen and avoids impurities from affecting the use of equipment and pipelines. This makes the device highly practical. The mounting ring 8 and filter screen 9 can be disassembled and cleaned through the mounting component 7. When disassembling, one end of the oxygen supply pipe 2 is first disconnected from the external oxygen supply equipment through the flange 1.

[0027] The regulating assembly includes a flow control valve 5 fixedly installed on the outer surface of the oxygen supply pipe 2. An oxygen flow meter 3 is fixedly installed on the right side of the outer surface of the oxygen supply pipe 2. The monitoring end of the oxygen flow meter 3 is located inside the oxygen supply pipe. A controller 4 is fixedly installed on the outer surface of the oxygen supply pipe 2 between the oxygen flow meter 3 and the flow control valve 5. Both the flow control valve 5 and the oxygen flow meter 3 are electrically connected to the controller 4. During operation, the oxygen flow meter 3 monitors the oxygen passing through the oxygen supply pipe 2. The monitoring by the oxygen flow meter 3 facilitates the operator's guidance on the amount of oxygen introduced into the bottom-blown furnace through the oxygen supply pipe 2. When it is necessary to adjust the oxygen supply, the operator can control the flow control valve 5 through the controller 4. The flow controller 4 can control the amount of oxygen introduced, thereby achieving the purpose of adjusting the amount of oxygen entering, and thus achieving the purpose of adjusting the silver content of the oxidized smelting material in the bottom-blown furnace.

[0028] The installation assembly 7 includes a continuous inner groove 71 formed on the inner wall of the oxygen supply pipe 2. Fixed rods 75 are fixedly connected to the inner groove 71 in all directions. A connecting rod 79 slides through the fixed rods 75. A compression assembly is installed inside the inner groove 71, passing through the fixed rods 75. One end of the connecting rod 79 is fixedly connected to a limiting plate 74. A spring 72 is fixedly connected between the limiting plate 74 and the inner groove 71. A continuous limiting groove 73 is formed on the outer surface of the installation ring 8. The limiting plate 74 is inserted into the limiting groove 73 on one side. During operation, the connecting rod 79 and the fixed rod 75 are slidably connected. When the extrusion assembly is working, the connecting rod 79 and the limiting plate 74 are moved. After the limiting plate 74 is inserted into the limiting groove 73, the mounting ring 8 is limited and installed. After the limiting plate 74 moves, the spring 72 is stretched and has a rebound force to facilitate the reset of the limiting plate 74. At the same time, the operation of the extrusion assembly facilitates the movement of the limiting plate 74 and facilitates the disassembly and reinstallation of the mounting ring 8 and the filter screen 9.

[0029] The extrusion assembly includes a through groove 76 formed inside the fixed rod 75. An extrusion block 78 is slidably connected inside the through groove 76. The extrusion block 78 is fixedly connected to one end of the connecting rod 79 that passes through the through groove 76. Sliding grooves 712 are formed on the right side of the inner groove 71, in all directions. A slider 713 is slidably connected inside the sliding groove 712. A spring 714 is fixedly connected between the slider 713 and the sliding groove 712. An extrusion rod 77 is fixedly connected to one side of the slider 713. One end of the rod 77 passes through the right side of the groove 76 and the recess 6. The outer surface of the extrusion rod 77 is in contact with the outer surface of the extrusion block 78. A slot 711 is provided on the outer surface of the extrusion rod 77. During operation, the extrusion rod 77 extrudes the extrusion block 78. After the extrusion block 78 is extruded, it drives the connecting rod 79 and the limiting plate 74 to move and insert into the limiting groove 73 to limit the installation of the mounting ring 8. When the limiting plate 74 moves, the spring 72 is stretched and has a rebound force. When the mounting ring 8 is disassembled, the extrusion rod 77 moves. 7. After the extrusion rod 77 moves, the position of the slot 711 will move. When the slot 711 corresponds with the extrusion block 78, the rebound force of the spring 72 will drive the limiting plate 74, the connecting rod 79, and the extrusion block 78 to move. The extrusion block 78 is inserted into the slot 711. This allows the limiting plate 74 to disengage from the limiting groove 73 and the mounting ring 8 to disengage from the limiting plate 74. It also keeps the position of the extrusion rod 77 after it is pulled in place. Moving the mounting ring 8 will allow the mounting ring 8 and the filter screen 9 to exit from inside the oxygen supply pipe 2. Disassembly is performed, and when reinstalling, first pull the squeezing rod 77, and then insert the mounting ring 8 and filter screen 9 into the oxygen supply pipe 2, so that the limiting groove 73 corresponds to the limiting plate 74. Then release the squeezing rod 77, and the squeezing rod 77 moves under the rebound force of the second spring 714, which squeezes the squeezing block 78 inside the slot 711. After the squeezing block 78 is squeezed, it drives the connecting rod 79 and the limiting plate 74 to move and insert into the limiting groove 73. The first spring 72 is also stretched to facilitate the movement and reset of the limiting plate 74.

[0030] One end of each of the four extrusion rods 77 is fixedly connected to a handle ring 710. The elastic coefficient of the second spring 714 is greater than that of the first spring 72. During operation, the handle ring 710 facilitates the movement of the four extrusion rods 77 together, and the extrusion rods 77 can be reset to extrude the extrusion block 78.

[0031] The extrusion block 78 is adapted to the slot 711. The outer surface of the extrusion block 78 and the inner sidewall of the extrusion groove are both set in an arc shape. During operation, it is convenient for the extrusion block 78 to be inserted into and detached from the slot 711.
