Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a testing and experimental device. Background Technology

[0002] In the aluminum electrolysis industry, the aluminum electrolysis cell, as the core equipment, undertakes the crucial task of electrolyzing alumina into metallic aluminum. During the electrolysis process, the electrode distance (i.e., the vertical distance from the bottom of the anode to the surface of the molten aluminum) between the anode carbon block and the aluminum melt mirror is a crucial parameter affecting current efficiency, energy consumption, and the quality of the molten aluminum. Even a slight change in the electrode distance can lead to uneven current distribution within the electrolysis cell, thereby affecting electrolysis efficiency and product quality. Therefore, real-time and accurate monitoring of the electrode distance is a critical aspect of aluminum electrolysis production.

[0003] Existing electrode distance testing devices all employ the iron rod method and the measuring rod method. The iron rod method involves the operator inserting an iron rod with a hook into the electrolytic cell, placing the hook against the bottom of the anode, and then measuring the position of the interface between the solidified electrolyte and the molten aluminum on the iron rod. The electrode distance value is determined by marking the point. The measuring rod method uses a measuring rod equipped with a level. The horizontal part of the bent end is placed against the bottom of the anode and kept horizontal. The distance from the upper surface of the measuring rod to the boundary line between the electrolyte and the molten aluminum is measured and recorded in 0.5 cm increments.

[0004] Existing electrode distance detection test devices suffer from measurement lag and are affected by fluctuations in the aluminum molten interface and human observation errors. The measurement results cannot reflect the dynamic changes in electrode distance in real time, and cannot meet the needs of industrial production for continuous monitoring. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a testing device that offers the advantages of real-time detection and easy maintenance. It solves the problems of existing electrode distance detection devices, which suffer from measurement lag and are affected by fluctuations in the aluminum molten interface and human observation errors, making it difficult for the measurement results to reflect the dynamic changes in electrode distance in real time and thus failing to meet the continuous monitoring needs of industrial production.

[0006] This utility model provides the following technical solution: a testing device, including an aluminum electrolytic cell and an anode carbon block, wherein an electrode distance detection component is arranged inside the aluminum electrolytic cell, the electrode distance detection component includes a guide tube fixedly connected inside the aluminum electrolytic cell, a filter tube fixedly connected to the bottom surface of the guide tube, a float ball slidably arranged inside the filter tube, and mounting blocks arranged opposite to each other inside the filter tube, with abutment blocks fixedly connected to the end surface of the mounting blocks away from the filter tube, a measuring display disk threadedly connected to the top surface of the guide tube, a connecting block fixedly connected to the bottom surface of the measuring display disk, a rangefinder fixedly connected to the bottom surface of the connecting block, and a cleaning component arranged inside the guide tube. The aluminum electrolytic cell is the core container of the electrolytic reaction, providing a high temperature, strong magnetic and strong corrosive environment to support the installation and operation of the electrode distance detection component. Its inner wall needs to withstand electrolyte erosion, therefore the filter tube needs to be directly fixed to the inner wall of the aluminum electrolytic cell to ensure that the liquid level fluctuation signal is directly transmitted to the float ball.

[0007] Preferably, the cleaning component includes scrapers that are fixedly connected to the bottom surface of the connecting block, and a support plate is fixedly connected to the bottom surface of each pair of scrapers. When the scrapers rotate, they scrape off the crystals and impurities on the inner wall of the guide tube and the filter tube.

[0008] Preferably, the outer sides of the scraper abut against the inner wall surfaces of the guide tube and the filter tube, and the support plate is positioned directly below the float, which can lift the float and carry it out of the guide tube.

[0009] Preferably, the bottom surface of the filter tube is fixedly connected to the inner wall surface of the aluminum electrolytic cell, and the initial height of the abutment block and the anode carbon block are on the same horizontal line. The filter tube is used to isolate high-temperature electrolyte crystals and impurities, preventing them from entering the guide tube and interfering with the movement of the float.

[0010] Preferably, the rangefinder is electrically connected to the measurement display panel, and both the rangefinder and the measurement display panel are located on the outside of the aluminum electrolysis cell. The measurement display panel is used to display the data measured by the rangefinder.

[0011] Preferably, the end of the mounting block away from the abutment block is fixedly connected to the inner wall surface of the scraper. The abutment block is positioned directly above the float. The abutment block prevents the float from rising excessively, so that the initial position of the float is the same as the initial position of the anode carbon block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By setting up the electrode distance detection component, the float ball tracks the fluctuation of the electrolyte liquid level in real time. Combined with the fixed reference relationship between the rangefinder and the stop block, continuous and accurate real-time monitoring of the electrode distance is achieved. At the same time, when the measuring display panel is disassembled by thread, the scraper and the support plate of the cleaning component rotate synchronously. This can not only scrape off the crystallized impurities on the pipe wall, but also carry the float ball out of the guide tube. This achieves simultaneous operation of pipeline cleaning and float ball maintenance, avoiding measurement interruption caused by manual intervention, and significantly improving the stability of electrolytic cell operation and maintenance efficiency.

[0014] 2. The coordinated design of the filter tube and scraper can effectively isolate the interference of high-temperature electrolyte crystals and impurities on the rangefinder. At the same time, the support plate lifts the float. When the scraper is pulled out of the guide tube, the support plate moves with it, thereby driving the float upward and bringing the float out of the guide tube at the same time, which facilitates the cleaning and maintenance of the float surface.

[0020] 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.

[0021] Please see Figure 1 - Figure 4This utility model provides an embodiment of a testing device, comprising an aluminum electrolytic cell 1 and an anode carbon block 2. An electrode distance detection component 3 is disposed inside the aluminum electrolytic cell 1. The electrode distance detection component 3 includes a guide tube 31 fixedly connected inside the aluminum electrolytic cell 1. A filter tube 32 is fixedly connected to the bottom surface of the guide tube 31. A float 33 is slidably disposed inside the filter tube 32. Mounting blocks 34 are disposed opposite each other inside the filter tube 32. Abutments 35 are fixedly connected to the surface of the mounting blocks 34 away from the filter tube 32. A measuring display disk 36 is threadedly connected to the top surface of the guide tube 31. A connecting block 37 is fixedly connected to the bottom surface of the measuring display disk 36. A rangefinder 38 is fixedly connected to the bottom surface of the 7. A cleaning component 39 is installed inside the guide tube 31. The bottom surface of the filter tube 32 is fixedly connected to the inner wall surface of the aluminum electrolysis tank 1. The initial height of the abutment block 35 and the anode carbon block 2 is at the same horizontal line. The rangefinder 38 is electrically connected to the measuring display panel 36. Both the rangefinder 38 and the measuring display panel 36 are set on the outside of the aluminum electrolysis tank 1. The anode carbon block 2 is the anode of the electrolysis reaction. The distance from its bottom to the aluminum liquid mirror surface is the electrode distance. The initial height of the abutment block 35 and the anode carbon block 2 is the same, serving as a fixed reference benchmark for electrode distance calculation, ensuring that the height of the float 33 measured by the rangefinder 38 can be directly converted into the electrode distance value. The guide tube 3... 1. The rangefinder 38 is protected from direct corrosion by the high-temperature electrolyte. 2. A guide channel is provided for the vertical movement of the float 33, preventing it from shifting due to liquid level fluctuations. 33. The filter tube 32 isolates high-temperature electrolyte crystals and impurities, preventing them from entering the guide tube 31 and interfering with the movement of the float 33. The filter holes allow the electrolyte level fluctuation signal to be transmitted to the float 33, which rises and falls synchronously with the electrolyte level. Its top remains in close contact with the liquid surface, serving as a dynamic sensor for the extreme distance change. 34 connects the scraper 391 and the abutment block 35, forming an integral structure and ensuring the synchronization of the cleaning assembly 39 with the extreme distance reference. 35 serves as a fixed reference point for extreme distance calculation, and its height... The initial height of the anode carbon block 2 is level with the vertical distance between the float 33 and the abutment block 35 is measured by the rangefinder 38 to indirectly obtain the polar distance value. The measurement display panel 36 is threaded to the top of the guide tube 31 and has a built-in signal processing module to convert the data from the rangefinder 38 into the polar distance value and display it. The rangefinder 38 uses laser or ultrasonic ranging technology to continuously emit signals to the top of the float 33 and receive the reflected waves. The height of the float 33 is obtained by calculating the round-trip time of the signal. The materials of the guide tube 31, filter tube 32, float 33, mounting block 34, abutment block 35 and support plate 392 are all made of high temperature and corrosion resistant ceramic or special alloy materials to ensure the long-term stability of the equipment.

[0022] Please see Figure 1 - Figure 4The cleaning component 39 includes scrapers 391 fixedly connected to the bottom surface of the connecting block 37. A support plate 392 is fixedly connected to the bottom surfaces of both scrapers 391. The outer sides of the scrapers 391 abut against the inner walls of the guide tube 31 and the filter tube 32. The support plate 392 is positioned directly below the float 33. The end of the mounting block 34 furthest from the abutment block 35 is fixedly connected to the inner wall of the scrapers 391. The abutment block 35 is positioned directly above the float 33. When the scrapers 391 rotate, they scrape away crystals and impurities from the inner walls of the guide tube 31 and the filter tube 32, preventing blockage and ensuring smooth movement of the float 33. When the support plate 392 rotates, it agitates the bottom electrolyte, preventing the float 33 from becoming stuck due to electrolyte viscosity. When the measuring display panel 36 is disassembled, the support plate 392 simultaneously lifts the float 33 and carries it out of the guide tube 31, facilitating cleaning and maintenance.

[0023] Working Principle: During the operation of the aluminum electrolysis cell 1, when the electrolyte level fluctuates due to electrolysis consumption or changes in operating conditions, the float 33 rises and falls synchronously with the liquid level within the filter tube 32. When the liquid level rises, the float 33 is pushed upwards and slides; when the liquid level falls, the float 33 falls back with the liquid level, its top always in close contact with the electrolyte level. The measuring display panel 36 is fixed to the top of the guide tube 31 via a threaded connection. Its bottom connecting block 37 drives the rangefinder 38 to extend vertically into the guide tube 31. The rangefinder 38 continuously emits signals to the top of the float 33 and receives reflected waves. By calculating the round-trip time of the signal, the height data of the float 33 is obtained in real time. Combined with the fixed reference relationship that the initial height of the abutment block 35 and the anode carbon block 2 are level, the vertical distance between the float 33 and the abutment block 35 is converted into a polar distance value and displayed on the measuring display panel 36. If the electrolyte level rises due to electrolyte replenishment or operational adjustments, the float... As the float 33 rises, the height of the float 33 detected by the rangefinder 38 increases, and the distance value decreases accordingly. Conversely, when the liquid level drops, the position of the float 33 decreases, the value measured by the rangefinder 38 decreases, and the distance value increases. When the measuring display panel 36 needs to be disassembled for maintenance, the screw-out action drives the connecting block 37 and the scraper 391 to rotate synchronously. The outer side of the scraper 391 is in close contact with the inner wall of the guide tube 31 and the filter tube 32. By rotating, it scrapes away crystals or impurities from the tube wall. At the same time, the support plate 392 rotates with the scraper 391, disturbing the electrolyte at the bottom to prevent the float 33 from getting stuck. The mounting block 34 connects the scraper 391 and the abutment block 35 into an integral structure. When the scraper 391 is pulled out of the interior of the guide tube 31, the support plate 392 will move accordingly, thereby driving the float 33 to move upward, and then synchronously bringing the float 33 out of the interior of the guide tube 31, thus facilitating the cleaning and maintenance of the surface of the float 33.
