Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hot and cold tank identification devices for electrolytic cells, and relates to an image acquisition device for identifying hot and cold tanks in an aluminum electrolytic cell. Background Art
[0002] During the aluminum electrolysis process, each electrolytic cell is equipped with a certain number of point-feeders, with normal feed intervals ranging from 1.5 to 3 minutes. This point-feeding system, combined with a computer control system, automatically adjusts the feed interval to adjust the feed volume, thus enabling a variety of quasi-continuous "on-demand feed" technologies to meet the alumina concentration control requirements of modern aluminum electrolysis processes.
[0003] The electrolytic cell has a well-preserved Al2O3 crust, which can cover the periphery and sides of the anode, reducing the anode from oxidation and burning. At the same time, it is a poor conductor of heat and can act as an insulator to reduce heat loss in the cell.
[0004] When unloading the electrolytic cell, the shell is first broken to expose the melt area of the electrolytic cell so that the newly added Al2O3 can be better dissolved into the electrolyte. This operation will cause flames to be generated at the shell unloading point of the electrolytic cell and accompanied by the generation of flames.
[0005] The condition of an aluminum reduction cell's flame hole is a crucial parameter reflecting the state of the aluminum electrolysis process. It reflects the cell's thermal state (hot or cold) and is directly related to the cell's current efficiency. Traditional identification methods rely on workers taking photographs. However, manual labor makes it difficult to achieve consistent quality, resulting in poor analysis accuracy. Furthermore, the numerous locations and cells involved in each cell are time-consuming and labor-intensive. Summary of the Invention
[0006] The technical problem to be solved by the utility model is to provide an image acquisition device for identifying hot and cold tanks in an aluminum electrolytic cell, which can realize image acquisition at different positions of the electrolytic cell and stable acquisition of images in different electrolytic cells, saving time and labor and improving the quality of acquired photos.
[0007] The solution implemented by the utility model is: an image acquisition device for identifying hot and cold tanks of an aluminum electrolytic cell, comprising an industrial-grade high-definition camera, which is mounted on a mounting plate, which is fixedly connected to the lower end of an electric push rod, and a casing of the electric push rod is fixedly connected to a horizontal sliding plate, which is connected to a horizontal beam through two slider guide pairs, and the horizontal beam is mounted on one side of a crane beam, and the horizontal sliding plate is driven to move by a connected lead screw nut pair, and the nut of the lead screw nut pair is fixedly connected to a nut seat at the bottom of the horizontal sliding plate, and both ends of the lead screw of the lead screw nut pair are fixedly connected to the horizontal beam through a bearing seat and one end extends out of the bearing seat and is connected to a drive motor, and the drive motor is mounted on the horizontal beam through a motor frame, and both ends of the crane beam move through a walking mechanism.
[0008] Furthermore, the industrial-grade high-definition camera is mounted on the mounting plate via a flange.
[0009] Furthermore, limit baffles are provided at both ends of the horizontal beam, and travel limit switches are installed on the limit baffles, and the slider of the slider guide pair can touch the travel limit switch.
[0010] Furthermore, a plurality of vibration-damping grooves are provided on the horizontal beam, and steel balls of different diameters are installed in each vibration-damping groove.
[0011] Furthermore, a shock-absorbing rubber pad is provided on the connection surface between the horizontal beam and the overhead crane beam.
[0012] The effects of the present invention are as follows: the present invention can realize the longitudinal movement of the industrial-grade high-definition camera through the walking mechanism, thereby realizing the acquisition of images of different electrolytic cells. By driving the horizontal sliding plate to move horizontally (along the length direction of the electrolytic cell) by the driving motor, it can realize the image acquisition of different positions of a single electrolytic cell. The telescopic mechanism of the electric push rod can realize the acquisition with optimal distance control, which not only avoids damage to the image acquisition equipment, but also realizes the acquisition of the best image quality. When in use, the electrolytic cell cover is opened to control the position of the camera horizontally and vertically, so as to realize the image acquisition of different electrolytic cells and a single electrolytic cell. No manual acquisition is required, which saves time and effort. In addition, the acquisition is stable and reliable, the quality of the acquired image is better, which is more conducive to the subsequent analysis and utilization, and improves the accuracy of the hot and cold cell discrimination.

[0016] The present invention will be further described below with reference to specific embodiments.
[0017] Example 1: Figure 1-2 As shown, an image acquisition device for identifying hot and cold tanks of an aluminum electrolytic cell includes an industrial-grade high-definition camera 101, which is mounted on a mounting plate 103 through a flange 102. The mounting plate 103 is fixedly connected to the lower end of an electric push rod 104. The housing of the electric push rod 104 is fixedly connected to a horizontal sliding plate 105. The horizontal sliding plate 105 is connected to a horizontal beam 107 through two slider guide pairs 106. The horizontal beam 107 is mounted on one side of a crane beam 108. The horizontal sliding plate 105 is driven to move by a connected screw nut pair 109. The nut of the screw nut pair 109 is fixedly connected to the nut seat at the bottom of the horizontal sliding plate 105. The screw of the screw nut pair 109 is fixedly connected to the nut seat at the bottom of the horizontal sliding plate 105. The two ends are fixedly connected to the horizontal beam 107 through bearing seats, and one end extends out of the bearing seat and is connected to the drive motor 110. The drive motor 110 is mounted on the horizontal beam 107 through a motor frame. The two ends of the overhead crane beam 108 are moved by the traveling mechanism 111. The traveling mechanism can achieve the longitudinal movement of the industrial-grade high-definition camera 101 and the infrared thermal imager 102, thereby realizing the acquisition of images of different electrolytic cells. The horizontal sliding plate driven by the drive motor can move horizontally (along the length of the electrolytic cell), which can realize the acquisition of images at different positions of a single electrolytic cell. The telescopic mechanism of the electric push rod can achieve the best distance control acquisition, which not only avoids damage to the image acquisition equipment but also achieves the best image quality acquisition. During use, the electrolytic cell cover is opened to control the position of the camera horizontally and vertically to realize the acquisition of images of different electrolytic cells and a single electrolytic cell.
[0018] Limit baffles 113 are set at both ends of the horizontal beam 107, and a travel limit switch 112 is installed on the limit baffle 113. When the slider of the slider guide pair 106 touches the travel limit switch 112, the driving motor stops moving, which can realize the control of the safe stroke and play a protective role.
[0019] In order to achieve the accuracy of acquisition, a plurality of vibration-damping grooves 114 are provided on the horizontal beam 107. Steel balls 115 of different diameters are installed in each vibration-damping groove 114, which can reduce the vibration generated by the movement of the entire overhead crane or the operation of its motor, thereby improving the stability and accuracy of image acquisition. In addition, a shock-absorbing rubber pad 116 is provided on the connection surface between the horizontal beam 107 and the overhead crane beam 108 to further achieve the effect of vibration isolation.
