Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum production control technology, specifically to a two-level measurement mobile data acquisition vehicle for aluminum electrolytic cells based on an infrared thermal imager. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] The electrolytic cell is the core equipment in aluminum electrolysis production. Its interior is composed of layers of different materials. The upper layer is the electrolyte (molten electrolyte), typically composed of cryolite and alumina, with a temperature usually between 950-980℃. Its function is to dissolve alumina and conduct current, enabling the electrolytic reaction to proceed. The lower layer is molten aluminum. During electrolysis, aluminum ions are reduced to liquid aluminum at the cathode, depositing at the bottom of the electrolytic cell to form a molten aluminum layer.

[0004] During electrolytic aluminum production, it is necessary to measure the horizontal levels of the electrolyte and molten aluminum in the electrolytic cell. Currently, this is a two-person operation: one person operates the measuring probe, while the other measures and records the values. The workflow requires that within a few tens of seconds, one operator holds the measuring probe horizontally, inserts it into the furnace bottom from the aluminum outlet of the electrolytic cell, holds it for 5-10 seconds, and then removes it and places it on the ground. The other operator, while the measuring probe remains at a high temperature, visually observes the color difference formed when the electrolyte and molten aluminum solidify on the probe, and quickly measures the vertical height of the solidification lines on the probe using a ruler. This information is then manually recorded in a logbook. After the measurement is completed, the data is returned to the workshop office and entered into a computer for analysis and storage.

[0005] This method, being manual measurement, suffers from significant errors and lacks timeliness in data recording and analysis, failing to reflect the electrolytic cell's production status promptly. Furthermore, the high temperatures within the electrolytic cell during aluminum electrolysis make manual measurement inherently dangerous.

[0006] Besides the traditional steel rod measurement method described above, sensors based on laser / infrared ranging or resistance probe methods can also be used for measurement. However, these sensors are expensive and generally suitable for newly built automated factories, presenting difficulties for retrofitting traditional factories. Furthermore, laser / infrared ranging requires regular calibration and is susceptible to accuracy degradation due to smoke and dust interference, while resistance probes are prone to corrosion and require frequent replacement. Therefore, most electrolytic aluminum manufacturing plants employ a combination of manual and automated measurement methods. Utility Model Content

[0007] To address the technical problems mentioned above, this invention provides a two-level mobile data acquisition vehicle for aluminum electrolysis cells based on an infrared thermal imager. It simulates manual operation by inserting / removing a steel rod from the electrolysis cell, then uses an infrared thermal imager to perform measurements. The measured data is uploaded to a backend data center via a network. This achieves digitization of measurement and networking of data acquisition at the aluminum electrolysis process end, improving data accuracy and real-time performance, reducing delays in production process control due to data latency, and reducing manual labor intensity. It is suitable for improving measurement technology and production processes in traditional aluminum electrolysis plants.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] This utility model provides a mobile data acquisition vehicle for two-level measurement of aluminum electrolytic cells based on an infrared thermal imager. The vehicle includes a body, on which a data acquisition unit connected to a back-end data center is mounted. The bottom of the body has wheels, and the top of the body has an X-axis push rod. The moving end of the X-axis push rod is connected to the fixed end of a Y-axis push rod, and the moving end of the Y-axis push rod is connected to a measuring probe. An infrared thermal imager and a backplate are located on the side of the vehicle body near the measuring probe's fixing device. The infrared thermal imager is connected to the data acquisition unit. The X-axis push rod drives the Y-axis push rod, along with the measuring probe, in the horizontal direction, while the Y-axis push rod drives the measuring probe in the vertical direction.

[0010] Furthermore, the X-axis push rod drives the Y-axis push rod, along with the measuring probe, to move horizontally towards or away from the sampling port of the electrolytic cell. The Y-axis push rod drives the measuring probe to move vertically to insert into or remove from the sampling port.

[0011] Furthermore, the measuring probe includes a measuring section and a positioning section arranged side by side, with the top ends of the measuring section and the positioning section connected by a connecting section.

[0012] Furthermore, the measuring and positioning parts are in a vertical position, while the connecting part is in a horizontal position.

[0013] Furthermore, during the measurement, the measuring unit is inserted into the sampling port, and when it reaches the set depth position, the positioning unit abuts against the ground at the edge of the electrolytic cell or the top of the cell wall.

[0014] Furthermore, the vehicle body is connected to an infrared thermal imager via a support rod, with the infrared thermal imager facing the back panel for shooting.

[0015] Furthermore, the measuring probe moves along a straight path driven by the X-axis push rod, and the infrared thermal imager is located on one side of this straight line.

[0016] Furthermore, the vehicle operates on the side closest to the sampling port of the electrolytic cell.

[0017] Furthermore, the vehicle body includes a frame, with the fixed end of the X-axis push rod connected to the top of the frame and the movable wheels connected to the bottom of the frame.

[0018] Furthermore, the moving wheels have a locking mechanism.

[0019] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0020] 1. The mobile data acquisition vehicle moves to the measurement position. The X-axis push rod drives the Y-axis push rod, along with the measuring probe, to move horizontally to above the sampling port of the electrolytic cell. The Y-axis push rod then drives the measuring probe vertically to insert it into the electrolytic cell through the sampling port. After a set time, the Y-axis push rod drives the measuring probe vertically to pull it out of the sampling port. The X-axis push rod then drives the Y-axis push rod, along with the measuring probe, to move horizontally, bringing the measuring probe between the infrared thermal imager and the imaging backplate. The infrared thermal imager acquires an infrared image of the measuring probe and sends it to the back-end data center for processing to obtain the liquid level data of the electrolyte and molten aluminum. By using a trolley carrying a measuring probe that can move horizontally and vertically, the manual steel probe measurement method is replaced, improving safety during measurement. The infrared image determines the temperature of the measuring probe, the temperature difference when the electrolyte and molten aluminum solidify on the surface of the measuring probe, and thus the liquid level position of the electrolyte and molten aluminum. This helps improve the accuracy of the measurement and allows for timely feedback on the production status of the electrolytic cell. It is suitable for use in traditional electrolytic aluminum production sites.

[0021] 2. When the measuring part of the measuring probe is inserted into the electrolytic cell from the sampling port, the positioning part abuts against the plane on which the sampling vehicle is running (such as the ground or the top of the electrolytic cell wall), ensuring that the bottom end of the measuring part extends below the surface of the molten aluminum and just reaches the bottom of the electrolytic cell.

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] This embodiment presents a two-level mobile data acquisition vehicle for aluminum electrolysis cells based on an infrared thermal imager. The vehicle carries a steel rod, which is inserted and removed from the electrolysis cell in a manner mimicking manual operation. Measurements are then taken using a lower-cost infrared thermal imager, and the measured data is uploaded to a backend data center via a network. This achieves digitization of measurement and networked transmission of data collected at the aluminum electrolysis process end, improving data accuracy and real-time performance, reducing delays in production process control due to data latency, and minimizing manual labor intensity. It is suitable for upgrading measurement technology and production processes in traditional aluminum electrolysis plants.

[0033] The basic measurement process of this embodiment is as follows: The data acquisition vehicle runs to the preset position of the electrolytic cell, connects the carrying measuring probe to the part to be measured to obtain the solidified electrolyte and aluminum liquid, obtains the measurement data by taking pictures, and transmits the measurement data to the background data center for further processing to obtain the electrolyte and aluminum liquid height.

[0034] like Figures 1-2As shown, the aluminum electrolytic cell two-level measurement mobile data acquisition vehicle based on infrared thermal imager includes a vehicle body 8, with moving wheels at the bottom of the vehicle body 8 and an X-axis push rod 4 at the top of the vehicle body 8. The moving end of the X-axis push rod 4 is connected to the Y-axis push rod 3, and the moving end of the Y-axis push rod 3 is connected to the measuring rod fixing device 9. The measuring rod fixing device 9 is used to fix the measuring rod 10. An infrared thermal imager 6 and a shooting backplate 5 are provided on the side of the vehicle body 8 near the measuring rod fixing device 9.

[0035] The movement of the X-axis push rod 4 drives the Y-axis push rod 3, along with the measuring probe 10, to move horizontally, causing the measuring probe 10 to gradually move away from the vehicle body 8 and towards the electrolytic cell; the Y-axis push rod 3 drives the measuring probe 10 to move vertically to the measurement position and insert it into the sampling port 11 of the electrolytic cell.

[0036] After a set time period, the Y-axis push rod 3 drives the measuring probe 10 to move vertically away from the sampling port 11. The moving end of the X-axis push rod 4 drives the Y-axis push rod 3, along with the measuring probe 10, to move horizontally to the position between the infrared thermal imager 6 and the imaging backplate 5. The infrared thermal imager 6, in conjunction with the imaging backplate 5, captures an infrared image of the measuring probe 11. After the infrared image is transmitted to the backend data center, the software in the backend data center processes the infrared image to obtain the temperature of the measuring probe 11 in the infrared image, and determines the height positions of the electrolyte liquid level and the aluminum liquid level.

[0037] After the measuring probe 11 leaves the sampling port 11, the electrolyte liquid and aluminum liquid 12 in the electrolytic cell solidify on the surface of the measuring probe 11. Due to the temperature difference between the electrolyte liquid surface and the aluminum liquid surface, the two sections of medium solidified on the measuring probe 11 further amplify the temperature difference due to their different heat dissipation rates after the measuring probe is pulled out. An infrared thermal imager can acquire an infrared image showing this temperature difference. By using the number of pixels corresponding to different temperature segments in the infrared image, the horizontal liquid level height of the electrolyte and aluminum liquid in the electrolytic cell can be calculated. The measurement principle used is consistent with the existing steel probe measurement method, which is simple and direct. The introduction of the data acquisition vehicle replaces manual operation, improving measurement efficiency and safety. The back-end data center can quickly obtain the temperature difference in the infrared image by processing the infrared image, thereby determining the liquid level height of the electrolyte and aluminum liquid, solving the timeliness problem of manual measurement.

[0038] It is important to note that the software and related algorithms for processing infrared images in the back-end data center can be based on mature existing technologies. The focus of this solution is on what kind of data acquisition vehicle structure can be used to simulate the manual operation of inserting and pulling the measuring probe into the electrolytic cell, thereby obtaining infrared images that meet the processing requirements of the back-end data center.

[0039] like Figure 1As shown, the electrolytic cell is fixed on the electrolytic cell frame 2 and has an anode guide rod 1 inserted into the slot. The electrolytic cell contains electrolyte liquid and aluminum liquid 12 and has a top cover. The top cover is provided with a sampling port 11. In this embodiment, the sampling port 11 is located at the edge of the electrolytic cell, which makes it easy for the data acquisition vehicle to move to the vicinity of the sampling port 11 on the side of the electrolytic cell, and then carry the measuring probe to insert and pull it out from the sampling port 11.

[0040] The mobile data acquisition vehicle moves to the electrolytic cell that needs to be measured, and the brake pedal is activated to lock the vehicle. The cell number is identified, for example, by scanning a QR code or using an electronic tag.

[0041] When sampling port 11 is opened, Y-axis push rod 3 and X-axis push rod 4 move, and measuring probe 10 is inserted into sampling port 11. After 10 seconds, it is retracted. After retraction, the measuring probe 10 is stopped at the designated position of the data collection vehicle by the movement of Y-axis push rod 3 and X-axis push rod 4.

[0042] As a further implementation, the Y-axis push rod 3 and X-axis push rod 4 are not limited to specific structural forms, as long as they can produce controllable linear displacement. Existing mature products can be used, such as cylinders, hydraulic cylinders, or ball screw mechanisms driven by motors. In this embodiment, the fixed end of the X-axis push rod 4 is connected to the top of the vehicle body 8, the moving end of the X-axis push rod 4 is connected to the fixed end of the Y-axis push rod 3, and the moving end of the Y-axis push rod 3 is connected to the measuring rod 10 through the measuring rod fixing device 9. Figure 1 With the Y-axis push rod 3 and the X-axis push rod 4 in an extended state, the measuring probe 10 is inserted into the sampling port 11 in this state; Figure 2 With the Y-axis push rod 3 and X-axis push rod 4 in a retracted state, the measuring probe 10 has been pulled out of the sampling port 11 and is stationary at the set position inside the mobile data acquisition vehicle.

[0043] As a further embodiment, the structure of the measuring probe 10 is as follows: Figure 3 As shown, the device includes a measuring unit 101 and a positioning unit 103 arranged side by side, with their top ends connected by a connecting part 102. The measuring unit 101 and the positioning unit 103 are in a vertical position, while the connecting part 102 is in a horizontal position. During measurement, the measuring unit 101 is inserted into the sampling port 11, and when it reaches a set depth, the positioning unit 103 abuts against the ground at the edge of the electrolytic cell or the top of the cell wall.

[0044] During measurement, the X-axis push rod 4 and the Y-axis push rod 3 drive the measuring rod 10 to move through the measuring rod fixing device 9, causing the measuring part 101 and the positioning part 103 to move horizontally or vertically synchronously. The horizontal movement causes the measuring part 101 to move to the space above the sampling port 11, and the vertical movement causes the measuring part 101 to be inserted into the interior of the electrolytic cell from the sampling port 11. When it is inserted to the set depth, the positioning part 103 abuts against the top of the electrolytic cell wall or the ground, indicating that the measuring part 101 has reached the limit position. The limit position here refers to the position where the bottom of the measuring part 101 just contacts the bottom surface of the electrolytic cell.

[0045] As a further embodiment, the length of the measuring unit 101 is determined according to the depth of the electrolytic cell, and the length of the positioning unit 103 is determined according to the height difference between the plane position of the collecting vehicle and the plane position of the bottom of the electrolytic cell.

[0046] As a further embodiment, when the measuring unit 101 is inserted into the electrolytic cell from the sampling port 11, the positioning unit 103 abuts against the plane on which the collection vehicle runs (e.g., the ground or the top of the electrolytic cell wall), ensuring that the bottom end of the measuring unit 101 extends below the surface of the molten aluminum and just reaches the bottom of the electrolytic cell.

[0047] As a further implementation, the sampling port 11 of different electrolytic cells is located at different positions, and the length of the connecting part 102 is determined according to the horizontal distance between the sampling port 11 and the collection vehicle, so as to meet the actual needs of the production site.

[0048] As a further embodiment, the materials and performance parameters of the measuring part 101, connecting part 102 and positioning part 103 of the measuring rod 10 are the same as those of the existing steel rod measuring method. The specific material selection and mechanical and thermal performance parameters are not specifically limited in this embodiment.

[0049] As a further embodiment, the measuring probe fixing device 9 is used to fix the measuring probe 10 to the moving end of the Y-axis push rod 3. The specific structure of the measuring probe fixing device 9 is not limited, and mature existing products can be selected. For example, a connecting plate can be set at the moving end of the Y-axis push rod 3, and the measuring probe 10 can be fixed to the connecting plate by fasteners.

[0050] An infrared thermal imager 6 and a camera backplate 5 are installed on the side of the vehicle body 8 near the measuring rod fixing device 9, as detailed below. Figure 4 As shown, the vehicle body 8 is connected to the infrared thermal imager 6 via a support rod 7, with the infrared thermal imager 6 facing the imaging backplate 5. After the measuring probe 10 remains in the electrolyte solution and aluminum liquid 12 in the electrolytic cell for a period of time, the Y-axis push rod 3 rises, causing the measuring probe 10 to be pulled out from the sampling port 11. The X-axis push rod 4 translates, causing the measuring probe 10 to move to a position between the infrared thermal imager 6 and the imaging backplate 5, as shown. Figure 4 As shown.

[0051] The measuring part 101 and the positioning part 103 in the measuring probe 10 are two slender rod-shaped parts. The length of the positioning part 103 is much smaller than that of the measuring part 101. When the measuring probe 10 is translated under the drive of the X-axis push rod 4, the positioning part 103 will pass through the space above the infrared thermal imager 6 without interfering with the movement of the infrared thermal imager 6. In order to avoid interference between the movement of the infrared thermal imager 6 and the measuring part 101 in the measuring probe 10, the translation path of the measuring probe 10 under the drive of the X-axis push rod 4 is a straight line, and the infrared thermal imager 6 is not on this straight line (for example, the infrared thermal imager 6 can be on one side of the straight line). In the infrared image acquired by the infrared thermal imager 6, the measuring probe 10 is located on one side of the vertical bisector of the image, which can be to the left or to the right.

[0052] When the X-axis push rod 4 moves and drives the measuring probe 10 to the position between the infrared thermal imager 6 and the imaging back plate 5, the infrared thermal imager 6 cooperates with the imaging back plate 5 to acquire the infrared image of the measuring probe 10.

[0053] Infrared images are sent to the backend data center for processing. Infrared thermal images represent the temperature distribution on the object's surface using different colors or grayscale levels. Through image grayscale conversion and processing, a linear relationship between grayscale and temperature is established, allowing the extraction of the temperature at each point in the image. Background temperature is removed, providing a clear visual representation of the temperature distribution of the measured probe. Based on the temperature distribution of the probe, the slope of the temperature curve and the temperature boundary point are determined. The number of pixels corresponding to different temperature segments on either side of the temperature boundary point is calculated. The number of pixels is then converted into the liquid level heights of the molten aluminum and electrolyte, based on the known physical length of the probe corresponding to each pixel.

[0054] The obtained data on the liquid level of aluminum and electrolyte are saved to form a report, which is then sent to the cloud platform via a communication module for process analysis, enabling real-time participation in the production process control of electrolytic aluminum.

[0055] After the measurement is completed, the mobile data acquisition vehicle moves to the next measurement point to continue the measurement.

[0056] As a further implementation, the back-end data center can be a data acquisition device, an industrial control computer, a communication module, and a battery installed on the acquisition vehicle. The data acquisition device acquires infrared images from the infrared thermal imager 6, sends them to the industrial control computer for image processing, and generates a report on the liquid level of the aluminum liquid and the electrolyte liquid. The report is then transmitted to the cloud platform using the communication module.

[0057] The back-end data center can also consist of only a data acquisition unit and communication module installed on the acquisition vehicle. The data acquisition unit transmits the acquired infrared image data to the cloud platform via the communication module. The cloud platform processes the images to obtain the liquid level heights of the aluminum melt and electrolyte, and generates reports. Considering the impact of the electrolytic cell temperature on equipment such as industrial control computers, the cloud platform processing method for infrared images is preferred.

[0058] The mobile data acquisition vehicle carries a measuring probe and obtains the molten aluminum and electrolyte solidified on the surface of the probe through insertion and extraction. The infrared thermal imager uses a fixed-focus infrared thermal imager. The measuring probe is fixed within a fixed depth of field according to the infrared thermal imager's viewing angle to acquire infrared images. The infrared images can be processed into liquid level data by an industrial control computer, or uploaded to a cloud platform, where the infrared images can be processed into liquid level data.

[0059] The industrial control computer or cloud platform calibrates the pixels of the infrared thermal imager and the physical length of the measuring rod, and calculates the liquid level height by using the number of pixels corresponding to different temperature ranges on the measuring rod pulled out of the electrolytic cell.

[0060] The mobile data acquisition vehicle can also carry more sensors to acquire other process parameters during electrolytic aluminum production and upload them to the cloud platform, such as... Figure 5 As shown, in addition to an infrared thermal imager, a thermocouple, a resistance temperature detector (RTD), or a current loop can also be installed. Similarly, temperature and / or current can be measured through the Y-axis push rod 3 and the X-axis push rod 4, as an extended implementation of this solution.

[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
