Description

Technical Field

[0001] This utility model belongs to the field of temperature measuring instrument technology, specifically relating to a thermal imaging intelligent temperature measuring instrument for the cathode part of an aluminum electrolysis cell. Background Technology

[0002] In the aluminum electrolysis production process, temperature control of the cathode steel bars and side heat dissipation windows of the electrolytic cell is crucial for monitoring the cell's operation, preventing sudden cell leakage accidents, and strengthening safety process management. During aluminum electrolysis production, leakage accidents mostly occur at the cathode steel bars and adjacent side heat dissipation windows. To achieve effective early warning, it is necessary to regularly inspect each electrolytic cell or periodically measure the temperature of the cathode steel bars and heat dissipation windows of abnormal cells. This allows production managers to understand the temperature changes in the electrolytic cell shell, determine the cell's operating parameters, and take effective measures to ensure the smooth operation of the production equipment. Simultaneously, the measured temperatures should be recorded and entered into a computer for archiving and analysis of equipment operating trends.

[0003] Currently, major aluminum electrolytic plants in China generally use infrared thermometers to measure the temperature of cathode steel bars, heat dissipation windows, and furnace bottom steel plates at the cathode surface of electrolytic cells. However, due to the complex structure of aluminum electrolytic cells, limited measurement space, and numerous measurement points, the current method relies primarily on manual measurement of the temperature at a single point in the channel area at the bottom of the electrolytic cell using an infrared thermometer. This requires recording the measurement point, which is time-consuming and cannot cover the entire surface. Furthermore, there is a safety risk of high-temperature electrolyte blocks falling. In addition, the working principle of an infrared thermometer is to determine the temperature of a target object by receiving its infrared radiation energy. The infrared sensor converts the received infrared radiation energy into an electrical signal, which is then displayed on a monitor. However, the measurement accuracy of infrared thermometers is affected by various factors, mainly including:

[0004] (1) The proper selection of infrared thermometers, especially the object distance ratio, is crucial; improper selection will affect the measurement results.

[0005] (2) When using an infrared thermometer, high aiming accuracy is required, and the aiming distance must be controlled within an effective range. Insufficient aiming accuracy will significantly affect the measurement results.

[0006] (3) The temperature above the cathode steel rod and heat dissipation window of the electrolytic cell is higher than that below. The current measurement method is to measure the temperature below, that is, to measure the temperature from the bottom of the furnace, which is not the highest temperature area of ​​the cathode steel rod and heat dissipation window. The measured temperature value cannot reflect the real data required for production. Moreover, the measurement route is at the bottom of the furnace, which is a limited space. In addition, there is a time and space overlap with the main production process. High-temperature materials and parts falling from the road surface process pose a safety hazard.

[0007] (4) When aluminum plants measure the temperature of the cathode steel rod and heat dissipation window of the aluminum electrolytic cell from above, the operators need to keep their necks up for a long time, which increases the labor intensity of the operators.

[0008] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

In use, the outer end of the extension tube extends from the electrolytic cell surface through the heat dissipation window grid into the temperature measuring area, shifting the temperature measurement path from the bottom of the electrolytic cell furnace to the surface of the electrolytic cell furnace.

In addition, the infrared thermal imaging module temperature measuring lens is set at the top of the outer end of the extension tube, which is located outside the device, making it easy to replace and maintain.

This design shifts the temperature measurement path from the bottom of the electrolytic cell to its surface, significantly improving the measurement angle and the measurement of high-temperature areas, ensuring temperature measurement accuracy, and simultaneously resolving the safety risks inherent in traditional temperature measurement paths. Furthermore, it effectively adjusts and controls the extension of the infrared thermal imaging module's temperature measuring lens to a suitable temperature measurement position below the heat dissipation window on the electrolytic cell surface, further enhancing temperature measurement accuracy.

[0031] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Example

[0033] See appendix Figure 1-2 A thermal imaging intelligent temperature measuring instrument for the cathode portion of an aluminum electrolysis cell includes a temperature measuring instrument body 1 and a temperature measuring system 2 disposed within the temperature measuring instrument body 1; wherein,

[0034] The thermometer body 1 includes a housing 11 with an installation interface 111 at the front end, an extension tube 12 that is inserted into and fixed in the installation interface 111 of the housing 11, and a limiter 13 that is fixed on the wall of the extension tube 12 and whose position is adjustable.

[0035] The temperature measurement system 2 includes a multi-functional touch screen module 21 fixed to the rear end of the housing 11, an infrared thermal imaging module processor 22 fixed inside the housing 11 and connected to the multi-functional touch screen module 21, a micro switch 23 and a 4G Internet of Things module 24, and an infrared thermal imaging module temperature measurement lens 25 fixed to the top of the outer end of the extension tube 12 and connected to the infrared thermal imaging module processor 22.

[0036] In this embodiment, the multi-functional touch screen module 21 is an ESP32-S3-Touch-LCD-3.5 touch screen development board, which has a good human-machine interface and can display temperature data in real time.

[0037] The infrared thermal imaging module is an ESP32-S3 infrared thermoforming module, which includes an infrared thermal imaging module processor 22 and an infrared thermal imaging module temperature measuring lens 25. This embodiment involves secondary development of the ESP32-S3 infrared thermoforming module: the infrared thermal imaging module temperature measuring lens 25 is modified into a split design, fixed to the top of the outer end of the extension tube 12, and connected to the infrared thermal imaging module processor 22 and the infrared thermal imaging module temperature measuring lens 25 using a data cable. The data cable is threaded through the extension tube 12, which has good insulation and heat insulation properties, thus enabling the infrared thermal imaging module temperature measuring lens 25 and... Data transmission between the infrared thermal imaging module processors 22; this design allows the infrared thermal imaging module's temperature-measuring lens 25 to be extended forward a certain distance. In use, the outer end of the extension tube 12 extends from the electrolytic cell surface through the heat dissipation window (grid heat dissipation window, with square dimensions of 52mm long, 32mm wide, and 40mm thick) into the temperature measurement area, shifting the temperature measurement path from the bottom of the electrolytic cell furnace to the surface (the heat dissipation window is laid on the surface of the electrolytic cell furnace). This significantly improves the measurement angle and the measurement of the high-temperature area, ensuring temperature measurement accuracy and eliminating the safety risks associated with traditional temperature measurement paths. Furthermore, the infrared thermal imaging module's temperature-measuring lens 25 is positioned at the top of the outer end of the extension tube 12, outside the device, facilitating replacement and maintenance.

[0038] Additionally, the micro switch is located on the handle of the housing; the 4G IoT module model is Hezhou Air780EP;

[0039] In this embodiment, a battery 14 connected to the multi-functional touch screen module 21, the infrared thermal imaging module processor 22, and the 4G Internet of Things module 24 is also fixed inside the housing 11.

[0040] Secondly, in this embodiment, the limiter 13 includes a connecting cylinder 131 and a limiting ring 132 integrally formed at one end of the connecting cylinder 131; a locking bolt 133 is threaded onto the connecting cylinder 131, and when the locking bolt 133 is tightened, the inner end of the locking bolt 133 abuts against the wall of the extension tube 12. When the outer end of the extension tube 12 extends from the heat dissipation window grid into the temperature measurement area, the limiter 13 abuts against the heat dissipation window to achieve a limiting effect, effectively adjusting and controlling the extension of the infrared thermal imaging module temperature measuring lens 25 to a reasonable temperature measuring position below the heat dissipation window of the electrolytic cell furnace, thereby improving the accuracy of temperature measurement. During use, the position of the limiter 13 can be adjusted according to actual needs. Specifically, loosen the locking bolt 133 so that the inner end of the locking bolt 133 separates from the wall of the extension tube 12, and then move the limiter 13 along the axial direction of the extension tube 12. Then tighten the locking bolt 133 so that its inner end abuts against the wall of the extension tube 12, and fix the limiter 13 on the extension tube 12.

[0041] In addition, in this embodiment, the thermal imaging intelligent temperature measuring instrument for the cathode part of the aluminum electrolysis cell also includes a client 3 that is connected to the 4G Internet of Things module 24.

[0042] Finally, it should be noted that the battery 14 is connected to the multi-functional touch screen module 21, the infrared thermal imaging module processor 22, and the 4G IoT module 24 via wires. The wires are equipped with a power switch for controlling the disconnection and connection of the circuit. When working, the power switch is turned on to supply power to the battery 14. After the temperature measurement work is completed, the power switch is turned off and the battery 14 stops supplying power. After turning on the power switch, the infrared thermal imaging module temperature measuring lens 25 is extended into the temperature measuring area through the grid heat dissipation window. When the infrared thermal imaging module temperature measuring lens 25 is working, the image is displayed on the multi-function display module 21. By manually adjusting the optimal interface for thermal imaging temperature measurement, the infrared thermal imaging module processor 22 captures the highest temperature of the heat dissipation window and the two cathode steel rods. The relevant data is transmitted to the multi-function touch screen module 21 via Bluetooth communication mode for temperature measurement image and data display. After the temperature measuring area and the highest temperature data are stable, the micro switch 23 is manually pressed. The highest temperature of the corresponding heat dissipation window and cathode steel rod will be stored in the memory of the multi-function touch screen module 21. At the same time, the multi-function touch screen module 21 triggers the 4G IoT module 24 (the two communicate via a data cable) to synchronously send the data to the client 3 for background storage and management.

[0043] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
