Abstract

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Example 1: Please refer to Figures 1 to 4This utility model provides a technical solution: a prebaked anode calcination resistance control device, the prebaked anode calcination resistance control device includes: a resistance control box 1, a connecting pipe 2 installed on the side wall of the resistance control box 1, a placement frame 3 installed on the outer end of the connecting pipe 2 by threaded connection, a telescopic joint 4 installed at the bottom center of the placement frame 3, the telescopic joint 4 facilitates the lifting adjustment component 7 to drive the mesh cylinder 6 to move so that the pipe is not broken off and the coke is conveniently put in, a fixing plate 5 is installed at the bottom of the telescopic joint 4, the mesh cylinder 6 is installed at the bottom of the fixing plate 5, and the lifting adjustment component 7 is installed at the top of the fixing plate 5;
[0021] In use, the placement rack 3 is placed on the electrolysis box, and the mesh cylinder 6 is placed in the electrolyte inside the prebaked anode of the roasting furnace. The coke is transported from the inside of the resistance control box 1 through the connecting pipe 2 and the telescopic joint 4 to the inside of the mesh cylinder 6 by the control of the resistance control box 1. The lifting adjustment component 7 is used to drive the mesh cylinder 6 to move up and down, so as to adjust the amount of coke placed in the electrolyte inside the mesh cylinder 6 and adjust the resistivity and shrinkage rate of the prebaked anode. During the roasting process, the resistivity of the anode is measured in real time by a resistance detection probe, and the measurement results are fed back to the control system. The lifting adjustment component 7 is used to facilitate the adjustment of the resistance of the prebaked anode during roasting, so as to achieve precise control of the resistivity and ensure that the resistivity of the anode is always kept within the set range, thereby improving the consistency and stability of the product.
[0022] Example 2: Based on Example 1, a specific structure and use of the lifting adjustment component 7 are provided. The lifting adjustment component 7 includes a rotating rod 8, which passes through the side wall of the placement frame 3. Gears 9 are installed on both sides of the rotating rod 8. The gears 9 are located on the side wall of the placement frame 3. A driving gear plate 10 is installed on one side of the gear 9, and a driven gear plate 11 is installed on the other side of the gear 9. The driving gear plate 10 and the driven gear plate 11 are placed symmetrically through the center of the gear 9. Both the driving gear plate 10 and the driven gear plate 11 can move through the interior of the placement frame 3. The bottom end of the driven gear plate 11 is fixed to the top end of the fixed plate 5. The top end of the fixed plate 5 has a hole 12, and the driving gear plate 10 moves inside the hole 12.
[0023] In use, the lifting adjustment component 7, through the lifting and lowering of the active toothed plate 10 and the meshing of the teeth of the gear 9, drives the gear 9 to move up and down inside the placement frame 3. In turn, through the meshing of the gear 9 and the driven toothed plate 11, the driven toothed plate 11 is driven to move up and down. When the active toothed plate 10 moves downward, it drives the gear 9 to rotate, which in turn drives the driven toothed plate 11 to move upward. This causes the fixing plate 5 and the mesh cylinder 6 at the bottom of the driven toothed plate 11 to move upward, thereby reducing the amount of coke inside the mesh cylinder 6 that is submerged in the electrolyte, thus increasing the resistivity of the prebaked anode. Conversely, when the active toothed plate 10 moves upward, it causes the driven toothed plate 11 to move downward, increasing the amount of coke inside the mesh cylinder 6 that is submerged in the electrolyte, thus decreasing the resistivity of the prebaked anode.
[0024] Example 3: Based on Example 2, a structure is provided with a drive lifting and adjusting component 7 to lift and move, thereby driving the mesh cylinder 6 to move and adjust the resistance. A fixed frame 13 is installed on the top of the placement frame 3, and a drive motor 14 is installed on the top of the fixed frame 13. A threaded rod 15 is installed on the output end of the drive motor 14. The threaded rod 15 is fixed to the inside of the placement frame 3 by bearings. A limit rod 16 is fixedly installed on the top of the placement frame 3. The threaded rod 15 and the limit rod 16 respectively pass through the top of the active toothed plates 10 on both sides.
[0025] In use, the drive motor 14 drives the threaded rod 15 to rotate under the power control system. Under the sliding support of the limit rod 16, the active toothed plate 10 moves up and down under thread engagement.
[0026] In actual use, the placement rack 3 is placed on the electrolysis box, and the mesh cylinder 6 is placed in the electrolyte inside the prebaked anode of the roasting furnace. The coke is transported from inside the resistance control box 1 through the connecting pipe 2 and the telescopic joint 4 to the inside of the mesh cylinder 6 via the control of the resistance control box 1. The drive motor 14, under the power control system, drives the threaded rod 15 to rotate. With the sliding support of the limit rod 16, the active toothed plate 10 moves up and down under threaded engagement. When the active toothed plate 10 moves downwards, it drives the gear 9 to rotate, which in turn drives the driven toothed plate 11 to move upwards. This, in turn, drives the fixed plate 5 at the bottom of the driven toothed plate 11 and the mesh cylinder 6 to move upwards, thereby reducing the amount of coke inside the mesh cylinder 6 submerged in the electrolyte. Reducing the amount of coke can increase the resistivity of the prebaked anode; conversely, when the active toothed plate 10 moves upward, the driven toothed plate 11 moves downward, increasing the amount of coke inside the mesh cylinder 6 submerged in the electrolyte, thereby reducing the resistivity of the prebaked anode. This allows for easy control of the amount of coke placed inside the electrolyte within the mesh cylinder 6, adjusting the resistivity and shrinkage rate of the prebaked anode. During the roasting process, a resistance detection probe is used to measure the anode resistivity in real time, and the measurement results are fed back to the control system. The lifting adjustment component 7 is used to facilitate the adjustment of the roasting resistance of the prebaked anode, achieving precise control of the resistivity. This ensures that the anode resistivity is always kept within the set range, improving product consistency and stability.
