Description

Technical Field

[0001] This utility model belongs to the field of precise sensing of aluminum electrolytic cells, and specifically relates to a temperature detection device for aluminum electrolytic cells. Background Technology

[0002] In the daily inspection of aluminum electrolysis production, temperature monitoring of the cathode steel rod, heat dissipation holes, and bottom of the electrolytic cell is an essential task. Changes in the temperature of the electrolytic cell directly determine the thermal balance stability of the entire cell, and damage to the cathode can easily lead to safety accidents such as aluminum leakage.

[0003] According to research, commonly used temperature measurement methods are mainly divided into two categories: contact and non-contact. Contact methods mainly include traditional thermocouples and the newer fiber optic temperature measurement technology; non-contact methods mainly include infrared thermometers and thermal imagers. Extensive experiments and field applications have shown that thermocouples suffer from inconvenient installation and complex, messy wiring; thermal imagers are expensive, and their lifespan in the harsh environment of aluminum electrolysis with high temperatures and strong magnetic fields remains to be verified; infrared thermometers suffer from inconsistent measurement results due to varying operator habits and differences in equipment performance between manufacturers. In contrast, fiber optic temperature measurement technology is generally easy to install, has lower costs, and is stable and reliable in operation.

[0004] To address the aforementioned issues and enhance the intelligent sensing capabilities of aluminum electrolysis cells, there is an urgent need to develop a temperature measurement device that is easy to install, maintain, cost-effective, stable, and reliable, in order to effectively address the challenges of heavy workload, high cost, and high operational risks associated with manual measurement. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a low-cost, easy-to-install, and stable aluminum electrolysis cell temperature detection device that enables automatic data acquisition, allowing staff to monitor the temperature changes of the steel bars and heat dissipation holes in real time, thereby upgrading manual inspection to reliable online monitoring.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum electrolysis cell temperature detection device, comprising an aluminum box with an open top, perforations around the aluminum box, a bolt connected to the center of the aluminum box, and support columns arranged symmetrically along the center inside the aluminum box.

[0007] The aluminum box has a square projection along the horizontal direction with a side length of 7cm. There are two symmetrically arranged through holes on one side of the aluminum box. The through holes are U-shaped holes. The bolts are M6*15.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: The aluminum electrolysis cell temperature detection device of this utility model has the characteristics of quick installation, simple maintenance and reliable operation. It can effectively replace manual inspection, significantly reduce labor intensity and improve work efficiency. The implementation of this utility model is of great significance to achieving "reducing manpower and increasing efficiency" and "using science and technology to promote safety".

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0014] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0015] Example 1

[0016] like Figures 1 to 2 As shown, this utility model provides a temperature detection device for an aluminum electrolysis cell, including an aluminum box 1 with an open top, through holes 2 around the aluminum box 1, a bolt 3 connected to the center of the aluminum box 1, and support columns 4 arranged symmetrically along the center inside the aluminum box 1.

[0017] The aluminum box 1 has a square projection along the horizontal direction with a side length of 7cm. There are two through holes 2 on one side of the aluminum box 1, which are arranged symmetrically. The through holes 2 are U-shaped holes. The bolt 3 is M6*15.

[0018] This utility model addresses the challenges of limited space for heat dissipation holes in aluminum electrolysis cells, high temperatures, and strong magnetic fields. By utilizing the strong magnetic environment, the aluminum box 1 is directly attracted to the heat dissipation holes and steel rods of the electrolysis cell that need to be measured using the magnetism of a magnet. The specific design is as follows, taking into account the on-site structure of the electrolysis cell.

[0019] The entire online temperature detection uses fiber optic temperature measurement technology. In the non-metallic section, a non-metallic optical cable is run from the fiber optic temperature measurement host to the bottom of the aluminum electrolysis tank, and then connected to the metallic section via a flange. In the metallic section, firstly, a samarium cobalt magnet is fixed to the surface of an aluminum box 1 with a side length of 7cm using bolts 3. Then, a 12m optical fiber is placed inside the aluminum box 1, inserted through a perforation 2 on one side of the aluminum box 1, and the optical fiber is coiled around the support column 4 3 times, about 50cm. Then, the optical fiber is passed out through the perforation 2 on the opposite side of the aluminum box 1 from the side where it entered. Finally, the aluminum box 1 is sealed with a hidden cover (not shown in the figure). For heat dissipation hole temperature measurement, there are 6 aluminum boxes 1 on one optical fiber, with 150cm of fiber space between each aluminum box, and 75cm fiber space at the beginning and end. Each metal optical fiber is connected by a flange. For steel rod temperature measurement, there are 8 aluminum boxes 1 on one optical fiber, with two aluminum boxes forming a group. Within each group, there is a 25cm fiber space between the aluminum boxes, and a 185cm fiber space between each group. There are 75cm fiber space at the beginning and end. Each metal optical fiber is connected by a flange. See details for further information. Figure 2 As shown, circles represent temperature acquisition points on the steel window, squares represent temperature acquisition points on the steel rod, and equilateral triangles represent flanges. After the temperature-measuring fiber is fixed in place, put on high-temperature gloves, hold aluminum box 1, and attach the magnet sideways to the heat dissipation plate and steel rod next to the heat dissipation hole of the electrolytic cell. Adjust the position of the hanging fiber to prevent it from being hit by falling high-temperature objects, which could damage the fiber.

[0020] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
