Description

Technical Field

[0001] This application relates to the field of aluminum electrolysis, and in particular to a measuring device and system for an aluminum electrolysis cell. Background Technology

[0002] In the process of electrolyzing aluminum using aluminum electrolytic cells, parameters such as the temperature and level of the electrolyte, and the aluminum level (the level of the molten aluminum) are crucial technical indicators in aluminum electrolysis production. These parameters significantly impact output, energy consumption, product quality, material balance, equipment wear and tear, and production management. Therefore, it is necessary to frequently measure the temperature and level of the electrolyte, as well as the level of the molten aluminum, during the electrolysis process. However, because the electrolysis temperature in aluminum electrolytic cells is typically between 920-980℃, the measurement of these parameters is extremely difficult due to the influence of high temperatures, strong corrosion, crusting, and strong magnetic fields. This leads to large measurement errors and low measurement efficiency, a persistent challenge in the industry. Utility Model Content

[0035] One embodiment of this application discloses a measuring device 10 for an aluminum electrolytic cell 20. This measuring device 10 is used in the field of aluminum electrolysis. The aluminum electrolytic cell 20 used in the aluminum electrolysis field has a cover plate 21 on its upper part and an outer shell 22. Inside, from bottom to top, are loaded substances such as molten aluminum 25, electrolyte 24, and slag 23. Furthermore, depending on the needs of aluminum electrolysis, an anode 26 is also provided inside. The measuring device 10 can operate on the side of the aluminum electrolytic cell 20, specifically for measuring the temperature and level of the electrolyte 24 and the level of the molten aluminum 25 in the aluminum electrolytic cell 20.

[0036] The measuring device 10 includes:

[0037] The detection assembly includes a probe 1 and an operating part 102. The probe 1 and the operating part 102 are arranged in an L-shape. The probe 1 is used to detect the temperature and level of the electrolyte 24 in the aluminum electrolysis cell 20, as well as the level of the aluminum liquid 25. The operating part 102 is used to operate and drive the probe 1 to perform detection operations.

[0038] For example, the detection assembly includes a probe 1 and an operating part 102. The probe 1 can extend into the aluminum electrolysis tank 20, specifically inserted into the bottom of the aluminum electrolysis tank 20 to contact the electrolyte 24 and the molten aluminum 25. The operating part 102 can be elongated or rod-shaped, and is used by the user to operate the measuring device 10, for example, by using both hands or a matching robotic arm, thereby moving and measuring the measuring device 10, including moving the probe 1 to perform detection operations.

[0039] In one embodiment, the operating unit 102 can drive the probe 1 to be inserted into the aluminum electrolysis tank 20, so that the end of the probe 1 can touch the bottom of the aluminum electrolysis tank 20, thereby causing the probe 1 to be coated with the aluminum liquid 25 and the electrolyte 24 from bottom to top. The operating unit 102 can also drive the probe 1 to be removed from the aluminum electrolysis tank 20.

[0040] In one embodiment, the operating unit 102 is provided with a device mounting position, so that other components of the measuring device 10 can be mounted on the operating unit 102. The probe 1 and the operating unit 102 are arranged in an L-shape, so that the user can easily hold the operating unit 102 to operate the probe 1, including moving the probe 1 into the aluminum electrolysis cell 20 and taking it out after detection.

[0041] The image acquisition component 7 is disposed on the operation unit 102 and includes a camera 109 and an image transmission module connected to each other. The camera 109 faces the probe 1 and is used to acquire images of the color change on the surface of the probe 1 taken out from the aluminum electrolysis cell 20, and send the acquired target image to the image transmission module for transmission.

[0042] For example, the image acquisition component 7 is mounted on the operation unit 102 and is used to acquire images of the probe 1 taken out of the aluminum electrolysis tank 20. After the probe 1 is taken out of the aluminum electrolysis tank 20, the substances adhering to the probe 1 react with the air, causing a change in the color of the adhering substances, which in turn changes the color of the probe 1 surface. Different substances adhering to the probe 1 exhibit different color changes. For example, the first color after the electrolyte 24 undergoes a chemical reaction with air is different from the second color after the aluminum liquid 25 undergoes a chemical reaction with air.

[0043] The image acquisition component 7 captures images of the color changes on the surface of the probe 1 removed from the aluminum electrolysis tank 20, including both still images and dynamic images, thereby generating a target image. Specifically, the image acquisition component 7 includes a camera 109 and an image transmission module. The camera 109 can be suspended below the operating unit 102, with its lens facing the probe 1. After the probe 1 is removed from the aluminum electrolysis tank 20, its surface is covered with electrolyte 24 and molten aluminum 25. The camera 109 can capture images of the surface of the probe 1, including both still and dynamic images, and generate a target image based on the captured images. Furthermore, a protective shell 108 can be provided around the camera 109 to protect it.

[0044] On one hand, after the camera 109 acquires the target image, the image acquisition component 7 can perform image analysis on the target image and generate corresponding analysis results. These analysis results are the measurement results of the electrolyte 24 and the aluminum liquid 25 by the measuring device 10. On the other hand, after the camera 109 acquires the target image, it can send the acquired target image to the image transmission module. The image transmission module then sends the target image to the control component 6, which performs image analysis on the target image and generates corresponding analysis results.

[0045] The control component 6 is disposed on the operation unit 102 and is connected to the probe rod 1 and the image acquisition component 7 respectively. The control component 6 is used to receive the temperature of the electrolyte 24 transmitted by the probe rod 1, control the operation of the image acquisition component 7, and receive the target image sent by the image transmission module to process the target image to obtain the detection result.

[0046] For example, the control component 6 is mounted on the operation unit 102 and connected to the probe 1. The probe 1 is equipped with a temperature measuring device. After the probe 1 is inserted into the aluminum electrolysis cell 20 and touches the bottom, the temperature measuring device on the probe 1 can measure the temperature of the electrolyte and send the temperature of the electrolyte 24 to the control component 6. The temperature of the electrolyte 24 is part of the detection result.

[0047] The control component 6 is connected to the image acquisition component 7. After the probe 1 is removed from the aluminum electrolysis tank 20, its surface is adhered with electrolyte 24 and molten aluminum 25. The image acquisition component 7 acquires an image of the surface of the probe 1 removed from the aluminum electrolysis tank 20 and sends the acquired target image to the control component 6. The control component 6 analyzes the target image, including analysis of static images and / or dynamic images. Based on the distribution of multiple colors on the surface of the probe 1 in the target image, the type of substance adhered to the probe 1 can be determined, where each color corresponds to a specific substance. Specifically, the relative positional distribution information of the molten aluminum 25 and electrolyte 24 distributed upwards from the end of the probe 1 can be determined, thereby determining the liquid level of the molten aluminum 25 and the liquid level of the electrolyte 24 in the aluminum electrolysis tank 20 based on this relative positional distribution information. Furthermore, based on the temperature and level of the electrolyte 24 and the liquid level of the molten aluminum 25, the detection result is determined.

[0048] The measuring device 10 of the aluminum electrolytic cell 20 in this embodiment has a simple structure and is easy to operate, which improves the measurement accuracy and efficiency of the electrolyte 24 level and temperature and the aluminum liquid 25 level in the aluminum electrolytic cell 20.

[0049] In one embodiment of this application, a reinforcement member is provided at the connection between the probe rod 1 and the operating part 102, the reinforcement member being used to reinforce the connection between the probe rod 1 and the operating part 102.

[0050] For example, the probe 1 and the operating part 102 are both L-shaped, so that the user can easily hold the operating part 102 to operate the probe 1. In order to strengthen the firmness between the probe 1 and the operating part 102, a reinforcement is constructed at the connection between the probe 1 and the operating part 102 to stabilize the connection between the probe 1 and the operating part 102.

[0051] In one embodiment, the reinforcement member can be a reinforcing rod, with one end fixedly connected to the probe rod 1 and the other end fixedly connected to the operating part 102. In another embodiment, the reinforcement member can be a plate-like object with a certain thickness, fixed at the connection between the probe rod 1 and the operating part 102, specifically, one side of which is fixed to the probe rod 1 and the other side of which is fixed to the operating part 102.

[0052] In one embodiment of this application, the probe 1 is provided with a temperature sensor 2. The temperature sensor 2 is connected to the control component 6 via a connecting line 101 and transmits the measured temperature of the electrolyte 24 to the control component 6. The connecting line 101 is arranged along the length direction of the probe 1 and the operating part 102.

[0053] For example, the temperature sensor 2 can be disposed on the outer surface of the probe 1, specifically at the contact portion between the probe 1 and the electrolyte 24, such that the probe 1 extends into the aluminum electrolysis tank 20, and after the end of the probe 1 touches the bottom, the temperature sensor 2 contacts the electrolyte 24 to measure the temperature of the electrolyte 24. After the temperature sensor 2 obtains the temperature of the electrolyte 24, it transmits the temperature of the electrolyte 24 to the control component 6 through the connecting line 101. The control component 6 generates a detection result based on the obtained temperature of the electrolyte 24.

[0054] Furthermore, the aforementioned connecting line 101 can be arranged along the length of the probe 1 and the operating part 102 to connect the temperature sensor 2 to the control component 6, so as to transmit the temperature of the electrolyte 24 measured by the temperature sensor 2 to the control component 6.

[0055] In one embodiment of this application, the measuring device 10 further includes a level 103, which is mounted on the operating part 102 and used to measure the level value of the operating part 102 in order to measure the detection angle of the probe rod 1.

[0056] For example, the measuring device 10 also includes a level assembly 5, which includes a level 103 and mounting hardware. The operating unit 102 can be integrally rod-shaped. The level 103 can be mounted on the upper side or side of the operating unit 102 via mounting hardware (such as screws and nuts) and arranged along the length of the operating unit 102 for easy viewing by the user. When the user operates the operating unit 102 to control the measuring device 10, the user can measure the level of the operating unit 102 using the level 103, thereby measuring the detection angle of the probe 1 during the detection of the aluminum electrolytic cell 20 by the probe 1. For example, when the operating unit 102 is perpendicular to the probe 1, the level 103 can be used to measure whether the probe 1 forms a 90-degree angle with the bottom of the aluminum electrolytic cell 20, thereby ensuring the accuracy of the detection measurement.

[0057] In one embodiment of this application, the control component 6 includes a display control unit 110, which is mounted on the operation unit 102 and is used to receive user control commands to control the measuring device 10 and to display the detection results and / or intermediate measurement information.

[0058] For example, the control component 6 includes a display control unit 110, which can be mounted on the upper side or side of the operation unit 102. This display control unit 110 can be a touch device, allowing the user to perform touch operations to generate control commands. The display control unit 110 then sends these control commands to the control component 6, which controls the measuring device 10 based on the received touch commands. For instance, the control command could be an instruction to control the image acquisition component 7 to operate, or an instruction to display the detection results.

[0059] In one embodiment, the display control unit 110 can also display the detection results, including the temperature and level of the electrolyte 24, and the level (aluminum level) of the aluminum liquid 25. The display method can be text, images, etc., and can be set according to actual needs.

[0060] In another embodiment, the display control unit 110 can also display intermediate measurement information, which may be relevant information during the measurement process, such as auxiliary information, time information, process information, debugging information, etc. Through the intermediate measurement information, the user can obtain status information such as the measurement process, current measurement stage, and adjustment status of the measuring device 10.

[0061] In one embodiment of this application, the control component 6 includes: an interface component 104, a motherboard, a temperature processing module 106, and an image processing module 107.

[0062] The temperature processing module 106 is used to process the received temperature of the electrolyte 24 and send the temperature processing result to the motherboard;

[0063] The image processing module 107 is used to process the received target image and send the image processing result to the motherboard;

[0064] The motherboard is connected to the display control unit 110 and the interface component 104 respectively. The determined detection results are sent to the display control unit 110 for display and / or sent to a remote device through the interface component 104.

[0065] For example, the temperature processing module 106 acquires the temperature of the electrolyte 24, processes the received temperature of the electrolyte 24 to form corresponding digital information, and sends it to the motherboard so that the motherboard can generate a detection result based on the temperature of the electrolyte 24. Similarly, the image processing module 107 analyzes and processes the received target image to generate corresponding image processing results, such as image recognition, and sends the image processing results to the motherboard. For example, the image processing module 107 can perform color recognition on the surface of the probe 1 in the target image to determine the material identity on the surface of the probe 1 and its distribution on the probe 1, thereby determining the liquid level of the aluminum liquid 25 and the liquid level of the electrolyte 24 in the aluminum electrolysis tank 20. The motherboard generates a corresponding detection result based on the liquid level of the aluminum liquid 25 and the liquid level of the electrolyte 24.

[0066] The motherboard is connected to both the display control unit 110 and the interface component 104. The motherboard houses the CPU 105 and other related hardware and software. The motherboard can obtain control commands from the display control unit 110 to control the image acquisition component 7, and can also send the generated detection results to the image acquisition component 7 for display.

[0067] In one embodiment, the motherboard can store the detection results locally or send them to a remote device via interface component 104. For example, the detection results can be stored in a remote storage space or remotely uploaded to the control room.

[0068] In one embodiment of this application, the image acquisition component 7 includes a timer connected to the camera 109. The timer is used to time the time it takes for the probe 1 to be removed from the aluminum electrolysis cell 20, generate a corresponding shooting command, and send the shooting command to the camera 109 to control the camera 109 to acquire images of the probe 1.

[0069] For example, a timer can be installed in an observable position on the operation unit 102 to time the relevant operation time of the measuring device 10, including the time it takes for the probe 1 to be removed from the aluminum electrolysis tank 20. This accurately determines the chemical reaction time of the molten aluminum 25 and electrolyte 24 adhering to the probe 1 with air. After the standard reaction time is reached, a reminder message can be generated instead of a shooting command to prompt image acquisition of the probe 1 surface. Alternatively, a corresponding shooting command can be generated and sent to the camera 109 so that the camera 109 can acquire an image of the probe 1 according to the shooting command. This prevents inaccurate identification of the color of the probe 1 surface and improves measurement accuracy.

[0070] In one embodiment of this application, a support member 4 is provided below the operation part 102, and the support member 4 is used to support the measuring device 10 in the working state on the tank wall of the aluminum electrolysis cell 20.

[0071] For example, a support member 4 is provided below the operating part 102. When the user uses the measuring device 10, the lower end of the support member 4 can be supported on the wall of the aluminum electrolysis tank 20 or on other supportable objects, thereby supporting the entire measuring device 10, making it easier for the user to flexibly operate the measuring device 10 and saving physical strength.

[0072] In one embodiment of this application, the operation part 102 is provided with a grip part 3, which is used by a user to grip the operation part 102.

[0073] For example, the grip 3 can be located in the middle of the operation part 102. The user can use both hands to grip the grip 3, thereby facilitating the user to operate the operation part 102, drive the probe 1 into the aluminum electrolysis tank 20, or take it out of the aluminum electrolysis tank 20.

[0074] This application embodiment also provides a measurement system for an aluminum electrolytic cell 20, including a measurement device 10 for the aluminum electrolytic cell 20 as described above, and a remote device connected to the measurement device for receiving the detection results and / or sending control commands to the measurement device.

[0075] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
