Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum production testing, and in particular to an automatic detection device for the liquid level of an electrolytic cell. Background Technology

[0002] In the electrolytic aluminum production process, the aluminum level and electrolyte level are key process parameters. The molten aluminum, as the "cathode" of the electrolytic cell, plays a role in conducting electricity, dissipating heat, and supporting the electrolyte. If its level is too high or too low, it will directly affect the aluminum production efficiency.

[0003] The electrolyte, as the "conductive medium" connecting the anode and the molten aluminum, is the site of alumina dissolution and electrolytic reaction. Its level is directly related to production energy consumption, equipment lifespan, and product quality. Therefore, accurate measurement of aluminum and electrolyte levels is the foundation of "refined control" in electrolytic aluminum production. Traditional measurement methods rely on manual operation, requiring workers to insert measuring tools into the electrolytic cell, wait a certain time, and then remove them to read the data. This method has the following drawbacks: First, it is time-consuming and labor-intensive, with low measurement efficiency, making it difficult to meet the testing needs of large-scale production; second, human factors have a significant impact, with operating techniques and reading errors during the measurement process leading to inaccurate data; third, data lacks effective recording and traceability, manual recording is prone to omissions and errors, and cannot be synchronized to the production management system in real time, which is not conducive to subsequent data analysis and process optimization. To address these issues, we propose an automatic electrolytic cell level detection device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] Please see Figure 1-4In this utility model, an automatic electrolytic cell level detection device includes a base plate 1. A steering component 2 and an adjustment component 3 are respectively installed on the upper surface of the base plate 1. The adjustment component 3 is located to the left of the steering component 2. A control component 4 is installed at the top of the adjustment component 3. A lifting component 5 is installed on the upper surface of the base plate 1. A detection component 6 is installed at the top of the lifting component 5. Two moving wheels 7 are installed on the bottom surface of the base plate 1. The moving wheels 7 are made of wear-resistant and non-slip rubber material and are equipped with wheel axles and fixed brackets. They are connected to the base plate 1 through the wheel axles and roll under the push of the operator or the control of the steering handle 21, driving the entire device to move. In conjunction with the steering component 2, the device can move. The wear-resistant and non-slip design ensures that the device moves stably on the workshop floor and meets the movement requirements of multi-tank measurement.

[0023] The lifting assembly 5 includes a lifting frame 16, which is located on the upper surface of the base plate 1. An electric push rod 11 is installed on the upper surface of the lifting frame 16, and a lifting plate 12 is installed at the output end of the electric push rod 11. The electric push rod 11 is fixed in the lifting frame 16. The electric push rod 11 receives a signal from the power system 17 and drives the lifting plate 12 to rise and fall in the vertical direction through telescopic movement, thereby driving the detection assembly 6 to rise and fall synchronously. This provides lifting power to the detection assembly 6, enabling the measuring rod 15 to be inserted into the electrolytic cell for measurement and to be removed. This replaces the manual insertion and removal of measuring tools, reduces labor intensity, and improves operational safety.

[0024] The detection component 6 includes an extension plate 13, which is located on the right side of the lifting plate 12. A limit rod 14 and a measuring rod 15 are respectively installed on the bottom surface of the extension plate 13. The limit rod 14 is located on the left side of the measuring rod 15. Two displacement sensors 20 are installed on the top of the measuring rod 15. The extension plate 13 fixes the limit rod 14 and the measuring rod 15 to the lifting plate 12. After the measuring rod 15 is inserted into the electrolytic cell, the aluminum liquid and electrolyte form a wetting mark on its surface. The limit rod 14 limits the maximum insertion depth of the measuring rod 15. The two displacement sensors 20 respectively detect the displacement data of the measuring rod 15 corresponding to the boundary line between the aluminum liquid and the electrolyte, and transmit it to the control panel 8. It directly contacts the aluminum liquid and electrolyte in the electrolytic cell to collect liquid level-related displacement data, providing raw data for liquid level height calculation. The limit rod 14 ensures the uniformity of the measurement benchmark and improves the measurement accuracy.

[0025] The adjustment assembly 3 includes a power system 17, which is located on the upper surface of the base plate 1. A connecting rod 18 is installed on the upper surface of the power system 17, and an adjustment handwheel 10 is installed at the top of the connecting rod 18. The power system 17 is electrically connected to the electric push rod 11 through a wire, and provides power support to the electric push rod 11. When the operator rotates the adjustment handwheel 10, a control signal is transmitted to the power system 17 through the connecting rod 18, thereby controlling the extension and retraction speed and stroke of the electric push rod 11. As the power control unit of the lifting assembly 5, it realizes precise control of the lifting action of the detection assembly 6, ensuring that the measuring rod 15 is smoothly inserted into or removed from the electrolytic cell, and ensuring the safety and stability of the measurement process.

[0026] The control component 4 includes a mounting rod 9, which is located at the top of the connecting rod 18. A control panel 8 is mounted on the left end of the mounting rod 9. The control panel 8 is electrically connected to the device via wires. The control panel 8 has a built-in main control board, a data storage module, and a data analysis module. Its surface is equipped with operation buttons, a display screen, and a data analysis function interaction area. The mounting rod 9 provides mounting support for the control panel 8. The main control board receives the detection signal from the displacement sensor 20 and calculates the aluminum level and electrolyte level using a preset algorithm. The data storage module automatically records complete data such as the time of each measurement, tank number, aluminum level, and electrolyte level. It supports quick querying and tracing based on time range, tank number, and other conditions. The data analysis module has multi-dimensional data analysis and detection functions. It can perform trend analysis on historical data of a single tank, generate liquid level change curves, and intuitively present the fluctuation patterns of aluminum liquid and electrolyte levels. It can also compare and analyze data from multiple tanks to identify differences in liquid levels in each tank. It also has a built-in normal liquid level threshold range to judge in real time whether the measured data exceeds the reasonable range. If an abnormality occurs, it will immediately trigger a pop-up window on the display screen and an audible and visual alarm. The system uses various methods to remind operators, facilitating timely troubleshooting of production issues. Operation buttons are used for inputting commands and setting analysis parameters. The display screen can switch between showing real-time measurement results, historical data lists, analysis curves, and abnormal warning information. The data analysis function interaction area allows operators to select analysis modes, adjust threshold parameters, and export analysis reports. Control panel 8, as the core control and interaction unit of the equipment, not only realizes data acquisition, processing, storage, display, and command input functions, but also deeply mines data value through newly added data analysis and detection functions, replacing manual reading, recording, and subsequent data analysis work, significantly improving operational convenience, data reliability, and the targeted nature of production process optimization.

[0027] The steering assembly 2 includes a seat 22 and a steering handle 21. Both the seat 22 and the steering handle 21 are located on the upper surface of the base plate 1. Two casters 19 are installed at the bottom of the steering handle 21. The operator sits on the seat 22 and turns the steering handle 21 to drive the casters 19 to turn. At the same time, the moving wheels 7 are used to adjust the direction and move the equipment, so as to realize the flexible turning and movement of the equipment in the electrolysis workshop. The seat 22 provides the operator with a comfortable operating posture, reduces labor intensity, and meets the movement needs of continuous measurement in multiple tanks.

[0028] The working principle of this utility model is as follows:

[0029] This automatic electrolytic cell level detection device, when in use, first involves the operator sitting on the seat 22 of the steering assembly 2 and moving the device to the target electrolytic cell by turning the steering handle 21, in conjunction with the moving wheels 7 and universal wheels 19, to complete the positioning. Next, the device is started via the operation buttons on the control panel 8, or by turning the adjustment handwheel 10 of the adjustment assembly 3. The power system 17 controls the extension of the electric push rod 11 in the lifting assembly 5, causing the lifting plate 12, extension plate 13, and the lower limit rod 14 and measuring rod 15 to descend vertically, allowing the measuring rod 15 to insert into the electrolytic cell. The descent stops after the limit rod 14 contacts the edge of the electrolytic cell, ensuring consistent insertion depth. Then... The measuring rod 15 stays in the electrolytic cell for a preset time, allowing the molten aluminum and electrolyte to form a stable wetting mark on its surface. Then, the adjusting handwheel 10 is rotated in the opposite direction or a command is issued through the control panel 8 to control the electric push rod 11 to retract, removing the measuring rod 15 from the electrolytic cell. The two displacement sensors 20 collect the displacement data of the measuring rod 15 corresponding to the boundary line between the molten aluminum and the electrolyte, and transmit it to the control panel 8. The main control board calculates the aluminum level and electrolyte level height through a preset algorithm, displays them on the display screen in real time, and stores them in the data storage module. Finally, after completing the measurement of the current cell, the device is moved to the next target cell, and the above steps are repeated to achieve continuous measurement.
