[0002] In the process of electrolyzing aluminum using aluminum electrolytic cells, electrolyte temperature measurement and automatic aluminum level measurement have always been difficult problems in the industry. Since the electrolysis temperature is between 920-980°C, it is very inconvenient to measure the temperature due to the influence of high temperature, strong corrosion, crusting, and strong magnetic field environment. The temperature parameters and aluminum level (liquid level) parameters of the aluminum electrolytic cell are important technical indicators in aluminum electrolysis production, because these two parameters have a great influence on output, energy consumption, product quality, material balance, equipment loss and production management.

[0033] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0034] The temperature measuring probe device 10 of an aluminum electrolysis cell 20 according to the embodiment of the present application can be applied to the field of aluminum electrolysis, such as Figure 1 As shown, it can be specifically applied to an aluminum electrolysis cell 20, which realizes aluminum electrolysis through the reaction of an anode 26 arranged inside. During the aluminum electrolysis process, aluminum liquid 25, electrolyte 24 and other substances such as crusted lime layer 23 may be contained in the aluminum electrolysis cell 20 from bottom to top. The temperature probe device 10 can measure the temperature of the electrolyte 24 in the aluminum electrolysis cell 20, and can also measure the liquid level of the electrolyte 24 and the liquid aluminum 25 (aluminum level) in the aluminum electrolysis cell 20.

[0035] Combination Figure 1 For example, the temperature measuring probe device 10 can be installed on the top of the aluminum electrolytic cell 20, and the control component of the temperature measuring probe device 10 controls the telescopic actuator 11 of the detection component to extend the probe rod 15, penetrate the crusted lime layer 23 in the aluminum electrolytic cell 20 to detect the target object, which includes the electrolyte 24 and the aluminum liquid 25. For example, the probe rod 15 can be extended to enter the electrolyte 24 and the aluminum liquid 25 to measure the temperature of the electrolyte 24. When the telescopic actuator 11 controls the probe rod 15 to return to the original position, the image processing component 14 (such as an artificial intelligence camera) analyzes the crust morphology and color characteristics of the aluminum liquid 25 and the electrolyte 24 on the adhesion layer of the probe rod 15 based on machine vision technology to achieve accurate measurement of the electrolyte liquid level and aluminum level (liquid level). In addition, the temperature measuring probe device 10 can automatically and continuously record the measurement data, analyze and process the measurement data. The adhesion layer adhered to the probe rod 15 can also be de-shelled. The measurement safety and measurement efficiency are improved.

[0036] The temperature measuring probe device 10 of the embodiment of the present application is described in detail below with reference to the accompanying drawings. Figure 2 As shown, the temperature measuring probe device 10 includes:

[0037] The detection component is used to detect the temperature and liquid level of the electrolyte 24 in the aluminum electrolysis cell 20, as well as the liquid level of the aluminum liquid 25.

[0038] A telescopic actuator 11 is connected to one end of the detection assembly, and is used to drive the probe rod 15 of the detection assembly to extend so as to be inserted into the target position in the aluminum electrolytic cell 20 for detection, and to drive the probe rod 15 to retract and reset;

[0039] The control component is connected to the detection component and the telescopic structure respectively, and is used to control the operation of the telescopic actuator 11, process the data collected by the detection component to generate corresponding detection results, and control the detection component to remove the shell of the probe rod 15 to keep the surface of the probe rod 15 clean.

[0040] Exemplarily, the aluminum electrolysis cell 20 realizes aluminum electrolysis through the reaction of the anode 26 disposed inside. During the aluminum electrolysis process, aluminum liquid 25, electrolyte 24 and other substances such as crusting ash layer 23 may be contained in the aluminum electrolysis cell 20 from bottom to top. The crusting ash layer 23 is a substance formed after the reaction of the anode 26. The aluminum liquid 25 is at the bottom of the aluminum electrolysis cell 20, the electrolyte 24 covers the aluminum liquid 25, and the crusting ash layer 23 covers the electrolyte 24.

[0041] The temperature measuring probe device 10 of the embodiment of the present application is installed on the top plate 21 or the bracket of the aluminum electrolytic cell 20, and the detection component is installed at the lower part of the control component. After the temperature measuring probe device 10 is installed, the control component is outside the aluminum electrolytic cell 20, and the detection component is at the top plate or the lower part of the bracket of the aluminum electrolytic cell 20. The detection component is provided with a probe rod 15, and the probe rod 15 is used to detect the electrolyte 24 and the aluminum liquid 25 in the aluminum electrolytic cell 20, and specifically can detect the temperature and liquid level of the electrolyte 24 in the aluminum electrolytic cell 20, and the liquid level of the aluminum liquid 25.

[0042] The telescopic actuator 11 is connected to one end of the detection assembly, and the probe rod 15 of the detection assembly is at the other end. After receiving the control command, the telescopic actuator 11 drives the probe rod 15 to extend toward the bottom of the aluminum electrolysis cell 20, so as to insert the probe rod 15 into the target position in the aluminum electrolysis cell 20 for detection. The target position can be the bottom of the aluminum electrolysis cell 20, or other positions in the cell determined according to empirical data. In one embodiment, the main body of the telescopic actuator 11 is a cylinder, which drives the probe rod 15 of the detection assembly to extend, contract and reset by controlling the air pressure.

[0043] The control component is connected to the detection component and the telescopic structure respectively, and can receive control instructions, or generate control instructions according to the user's operation, so as to control the extension, contraction and reset of the telescopic actuator 11. And control the detection component to process the detection data, and then obtain the detection result. Or receive the detection data sent by the detection component, process the detection data to obtain the detection result. Specifically, when the probe rod 15 is extended and inserted into the electrolyte 24, the control component can control the detection component to start the temperature measurement operation. When the probe rod 15 is extended and inserted into the bottom of the aluminum electrolysis cell 20, contacts the aluminum liquid 25 and retracts to the reset position, the control component can control the detection component to shoot the adhesion layer on the probe rod 15. Since the adhesion layer formed by the aluminum liquid 25 and other substances is different in shape and color, image recognition is performed based on this to determine the liquid level of the electrolyte 24 and the liquid level of the aluminum liquid 25 (aluminum level).

[0044] In one embodiment, the outer surface of the probe rod 15 is configured with an adhesion structure, so that the aluminum liquid 25 can be easily adhered to the probe rod 15 when the probe rod 15 contacts the aluminum liquid 25. For example, the adhesion structure can be a fine groove with a specific shape. When the probe rod 15 is inserted into the aluminum liquid 25, the aluminum liquid 25 can be adhered to the probe rod 15 through the fine groove. For another example, the material of the probe rod 15 can be constructed based on empirical data to enable the aluminum liquid 25 to adhere to the probe rod 15, thereby facilitating measurement.

[0045] In addition, the control component also controls the detection component to remove the shell of the probe rod 15, that is, to remove the adhesive layer on the probe rod 15. The specific means of removing the shell can be through vibration, knocking, physical removal and other means to keep the surface of the probe rod 15 clean, so as to facilitate the use of the probe rod 15 to measure the temperature and liquid level of the electrolyte 24 and the liquid level of the aluminum liquid 25. In one embodiment, since the surface of the probe rod 15 is kept clean, the control component can automatically control the temperature probe device 10 to intermittently measure the temperature and liquid level of the electrolyte 24 and the liquid level of the aluminum liquid 25 without affecting the measurement accuracy.

[0046] Further explanation, in the embodiment of the present application, the detection component includes an image processing component 14, a shell removal component 13 and a temperature measurement component 16. The image processing component 14 is arranged on one side of the probe rod 15, and identifies the adhesion layer on the probe rod 15 when the probe rod 15 performs a detection operation, so as to determine the liquid level of the electrolyte 24 and the liquid aluminum 25 based on the recognition result; the shell removal component 13 is arranged on one side of the probe rod 15, and removes the shell of the adhesion layer on the probe rod 15 when the probe rod 15 performs a detection operation; the temperature measurement component 16 (or a thermocouple detection component) is connected to the probe rod 15, and is used to measure the temperature of the probe rod 15 to determine the temperature of the electrolyte 24.

[0047] Exemplarily, the image processing component 14 is disposed on one side of the probe rod 15. When the probe rod 15 performs a detection operation on the aluminum liquid 25, an adhesion layer is adhered to the originally clean probe rod 15. The adhesion layer is formed by the aluminum liquid 25, the electrolyte 24 and the crusted lime layer 23 adhering to the probe rod 15. However, the adhesion layer formed by different substances has different shapes, colors and structures. The image processing component 14 can take a picture of the adhesion layer on the probe rod 15 and perform image recognition, thereby determining the position information of the aluminum liquid 25 on the probe rod 15 based on the recognition result, and then calculating the liquid level of the electrolyte 24 and the liquid aluminum 25 in the aluminum electrolytic cell 20 based on the position information, the telescopic distance of the probe rod and other parameters.

[0048] The shell removal component 13 is installed on one side of the probe rod 15, and can be on the same side of the probe rod 15 as the image processing component 14, or on a different side. When the probe rod 15 performs a detection operation, an adhesive layer will adhere to the probe head (or the end) of the probe rod 15. A knocking vibration part is constructed on the shell removal component 13. After completing the measurement of the liquid level of the electrolyte 24 and the liquid aluminum 25, the probe rod 15 is in a reset state, and the knocking vibration part can vibrate, knock, etc. on the probe rod 15 to remove the adhesive layer. Thereby ensuring the accuracy of measuring the aluminum liquid 25 using the probe rod 15 again.

[0049] The temperature measuring probe device 10 of the aluminum electrolysis cell 20 of the embodiment of the present application controls the probe rod 15 to extend into the aluminum electrolysis cell 20 through the control component to automatically measure the electrolyte temperature, the liquid level of the electrolyte 24 and the liquid aluminum 25. The safety of operation and the measurement accuracy are improved. At the same time, the adhesion layer on the probe rod 15 can also be automatically deshelled to keep the probe rod 15 clean, so that the temperature measuring probe device 10 can perform the measurement operation again, which improves the measurement efficiency.

[0050] In one embodiment of the present application, the shell removal component 13 is connected to the control component, and the shell removal component 13 has a knocking and vibration part, which is arranged close to the probe rod 15. When the shell removal component 13 receives the shell removal instruction from the control component, the knocking and vibration part knocks and / or vibrates the probe rod 15 to remove the adhesion layer.

[0051] Exemplarily, the shell removal component 13 is connected to the control component, and the control component can send a shell removal instruction to the shell removal component 13 under certain circumstances. For example, when the control component determines that the temperature measuring probe device 10 has completed the measurement of the temperature and liquid level of the electrolyte 24, and the liquid level of the aluminum liquid 25, the shell removal instruction can be sent to the shell removal component 13. The shell removal component 13 starts the knocking vibration part to vibrate and / or knock the adhesion layer on the probe rod 15, thereby removing the adhesion layer on the probe rod 15. In this embodiment, the shell removal component 13 is installed on one side of the probe rod 15, and the knocking vibration part is arranged close to the probe rod 15, so that the active end of the knocking vibration part is close to the probe rod 15. When the shell removal component 13 receives the shell removal instruction, the active end of the knocking vibration part continuously knocks and / or vibrates the probe rod 15, so that the adhesion layer on the probe rod 15 falls off, keeping the probe rod 15 clean.

[0052] In one embodiment of the present application, one end of the temperature measuring component 16 is fixedly connected to the probe rod 15, and the other end of the temperature measuring component 16 is movably connected to the control component through a telescopic cable 17, so that the temperature measuring component 16 can move relative to the control component following the extension and retraction of the probe rod 15, and transmit the measured temperature of the electrolyte 24 to the control component through the telescopic cable 17.

[0053] Exemplarily, the detection assembly includes a temperature measuring assembly 16 that can measure the temperature of the electrolyte 24 in the aluminum electrolytic cell 20 by measuring the temperature of the probe rod 15. One end of the temperature measuring assembly 16 is fixedly connected to the probe rod 15 or integrally formed, so that it can move with the movement of the probe rod 15 and change relative position relative to the control assembly. The other end of the temperature measuring assembly 16 is movably connected to the control assembly through a telescopic cable 17. The telescopic cable 17 can be extended or contracted by an elastic mechanism, such as through a "spring spring" or a "disc spring", and is extended under the driving action of the probe rod 15. When the probe rod 15 contracts, the telescopic cable 17 contracts under the action of elastic force. In addition, the telescopic cable 17 in this embodiment has a data transmission function. When the probe rod 15 is extended into the electrolyte 24, the temperature measuring assembly 16 can obtain the temperature of the electrolyte 24 by measuring the temperature of the probe rod 15 because the probe rod 15 has good thermal conductivity. The temperature of the electrolyte 24 is transmitted to the control assembly through the telescopic cable.

[0054] In one embodiment of the present application, a cable storage box 184 for storing the telescopic cable 17 is installed in the control component, and the cable storage box 184 stores or releases the telescopic cable 17 as the displacement of the temperature measuring component 16 relative to the control component changes.

[0055] Exemplarily, one end of the telescopic cable 17 can be fixedly connected to the probe rod 15, and the other end can be movably connected to the cable storage box 184. The cable storage box 184 is used to store the telescopic cable 17, and when the telescopic cable 17 is stretched by external force, the telescopic cable 17 is released and extended. The telescopic cable 17 is stored when it is not stretched by external force or receives reverse thrust. In this embodiment, the temperature measuring component 16 is fixedly connected to the probe rod 15. When the probe rod 15 moves to the bottom of the aluminum electrolysis cell 20, the temperature measuring component 16 gradually pulls the telescopic cable 17 out of the cable storage box 184, and the cable storage box 184 gradually releases the telescopic cable 17. When the probe rod 15 is measured, it is gradually approached to the top of the aluminum electrolysis cell 20 during the process of being retracted by the control component. The cable storage box 184 gradually stores the telescopic cable 17 through the elastic action of the "spring spring" or "disc spring". Thereby, the telescopic cable 17 can always be kept in a taut state.

[0056] In one embodiment of the present application, the adhesion layer includes a crusting material of the electrolyte 24 and a crusting material of the aluminum liquid 25, and the image processing component 14 is further used to capture an image of the adhesion layer, perform image recognition on the captured image, determine the liquid level of the electrolyte 24 and the liquid level of the aluminum liquid 25 based on the corresponding image recognition results, and transmit the corresponding liquid level information to the control component, or send the captured image to the control component so that the control component performs image recognition on the image and determines the liquid level of the electrolyte 24 and the liquid level of the aluminum liquid 25 based on the corresponding image recognition results.

[0057] Exemplarily, the adhesion layer adhered to the probe 15 includes the crust material of the electrolyte 24, the crust material of the aluminum liquid 25, and the mixed material, and the color state, morphology and other characteristics of each material in the adhesion layer are different. The image processing component 14 can be an artificial intelligence camera, which will obtain the image of the adhesion layer and perform artificial intelligence image recognition based on the characteristics of the adhesion layer. In one embodiment, on the one hand, the characteristics of the adhesion layer can be image recognized using empirical data; on the other hand, the image recognition model installed in the image processing component 14 can also be trained using training data, and the characteristics of the adhesion layer can be image recognized using the trained image recognition model, and then based on the corresponding image recognition results, and based on the positions of the electrolyte 24 and aluminum liquid 25 adhered to the probe 15 in the adhesion layer, and the elongation length of the probe 15 and other data, the liquid level of the electrolyte 24 and the liquid aluminum 25 are calculated, and the corresponding liquid level information is transmitted to the control component, and the control component can display the liquid level of the electrolyte 24 and the liquid aluminum 25, or send it to other devices to let the user know.

[0058] In another embodiment, after the image processing component 14 captures the image of the adhesion layer, it may not perform recognition processing on it or, if the adhesion layer cannot be accurately recognized, send the image of the adhesion layer to the control component, and the control component, or the control component in conjunction with related auxiliary components, may perform image recognition on the image, thereby improving image recognition efficiency and accuracy.

[0059] In one embodiment of the present application, the image processing component 14 has a camera, and the image processing component 14 is suspended below the shell removal component 13 , and the camera faces the probe rod 15 .

[0060] Exemplarily, the image processing component 14 has a camera that can photograph the adhesion layer on the probe rod 15. The image processing component 14 is suspended below the shell removal component 13, such as being suspended below the outer side of the shell removal component 13, so that the camera and the shell removal component 13 are located on the same side of the probe rod 15, making the structure of the detection component more streamlined.

[0061] In one embodiment of the present application, Figure 3 As shown, the control assembly includes a master control component 12 and an execution structure component 18 connected to each other.

[0062] The execution structure component 18 is provided with a pipeline 183 connected to the telescopic actuator 11 and a solenoid valve 182 for controlling the pipeline 183. The solenoid valve 182 controls the fluid or gas in the pipeline 183 according to the received control instruction, so as to control the telescopic actuator 11 to drive the probe 15 to extend or contract.

[0063] The master control component 12 is provided with a control system 123, and the control system 123 is used to control the execution structure component 18, and control the detection component and generate corresponding detection results.

[0064] Exemplarily, the control component includes a main control component 12 and an execution structure component 18 connected to each other. The main control component 12 is used to control the temperature measuring probe device 10 as a whole, including controlling the execution structure component 18 and the detection component, and is provided with an input terminal 125 and an output terminal 126 for data input and output. The main control component 12 can control the detection component to complete the corresponding detection action and determine the corresponding detection result. The main control component 12 is provided with a control system 123, including an operating unit 122, a display unit 121, an indicator light, and a main board, etc., wherein the operating unit 122 is used to accept user operations, the display unit 121 is used to display the detection results and detection intermediate information, and the main board is provided with a CPU 124 to support related hardware and software.

[0065] The execution structure component 18 is provided with a pipeline 183 connected to the telescopic actuator 11. The pipeline 183 can provide fluid or gas, such as air, hydraulic oil, etc., to the telescopic actuator 11, and drive the telescopic actuator 11 to move through the fluid or gas. The execution structure component 18 is also provided with a solenoid valve 182, which is arranged on the pipeline 183 and is used to control the flow of the fluid or gas in the pipeline 183, including the fluidity and directionality of the fluid or gas. In addition, the execution structure component 18 is also provided with an air inlet 181 for gas interaction with the outside world.

[0066] For example, the telescopic actuator 11 is a cylinder, and the actuator component 18 controls the gas in the pipeline 183 through the solenoid valve 182 to inflate or deflate the cylinder to drive the cylinder to work, thereby causing the cylinder to drive the probe rod 15 to extend or contract.

[0067] In one embodiment of the present application, an intermittent detection program is installed in the control component, and the intermittent detection program is used to control the temperature probe device 10 to intermittently detect the temperature of the electrolyte 24, the liquid level of the electrolyte 24 and the liquid aluminum 25.

[0068] Exemplarily, the intermittent detection program can start the temperature probe device based on a preset interval, such as setting a preset interval according to the needs of the usage scenario to control the temperature probe device 10 to intermittently detect the aluminum electrolysis cell 20 multiple times at the preset interval, thereby continuously obtaining the temperature of the electrolyte 24, the liquid level of the electrolyte 24 and the liquid aluminum 25 multiple times, thereby reducing the detection error and allowing the user to more accurately determine the overall working status of the aluminum electrolysis cell 20.

[0069] In one embodiment of the present application, the aluminum electrolysis cell 20 has a top plate 21 or a bracket above it, and the detection component has a mounting portion above it. The temperature probe device 10 is installed on the top plate 21 or the bracket of the aluminum electrolysis cell 20 through the mounting portion so that the detection component can extend into the interior of the aluminum electrolysis cell 20.

[0070] Exemplarily, the side of the aluminum electrolytic cell 20 has a cover plate 22 (smoke hood), the top of the aluminum electrolytic cell 20 has a top plate 21 or a bracket, the bottom of the aluminum electrolytic cell 20 is loaded with aluminum liquid 25, electrolyte 24, and crusted lime in sequence, and the aluminum electrolytic cell 20 is also installed with an anode 26 for electrolyzing aluminum. The temperature probe device 10 has a mounting portion. The mounting portion is arranged between the control component and the detection component. The temperature probe device 10 is installed on the top plate 21 or the bracket of the aluminum electrolytic cell 20 through the mounting portion, so that the control component is outside the aluminum electrolytic cell 20, and the detection component is inside the aluminum electrolytic cell 20, and then under the control of the control component, the detection component can extend into the bottom of the aluminum electrolytic cell 20 to detect the temperature and liquid level of the electrolyte 24 loaded in the aluminum electrolytic cell 20, as well as the liquid level of the aluminum liquid 25.

[0071] In one embodiment of the present application, a distance sensor is provided on the detection component. When the distance sensor detects that the distance between the knocking vibration part and the probe of the probe rod 15 is within the range of 300 mm to 800 mm, the detection component controls the knocking vibration part to knock and / or vibrate the probe rod 15.

[0072] Exemplarily, a distance sensor is provided on the detection assembly, and the distance sensor can detect the moving distance of the probe of the probe rod 15, so as to determine the distance between the knocking vibration part and the probe of the probe rod 15. After the probe rod 15 detects the aluminum liquid 25 and the electrolyte 24 and shrinks, the distance between the probe of the probe rod 15 and the knocking vibration part gradually decreases. When the distance sensor senses that the distance between the knocking vibration part and the probe of the probe rod 15 is within the range of 300mm to 800mm, it indicates that the probe rod 15 can be vibrated, so that the adhesion layer on the probe rod 15 can be quickly and completely removed. The above-mentioned range of 300mm to 800mm is a scientific and reasonable range obtained through a large number of production practices. Within this range, the detection assembly controls the knocking vibration part to knock and / or vibrate the probe rod 15 to achieve an excellent cleaning effect. The cleaning of the probe rod 15 is guaranteed so that it can be reused. Preferably, when the distance sensor detects that the distance between the knocking vibration part and the end of the probe of the probe rod 15 is 400 mm or 550 mm, the detection component controls the knocking vibration part to knock and / or vibrate the probe rod 15.
