Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a mounting and fixing device for a nickel electrolysis cell solution temperature detection sensor. Background Technology

[0002] During operation, the internal electrolyte temperature of a nickel electrolytic cell fluctuates with process variations. The main reasons for these temperature changes are: firstly, the solution in the electrolytic cell reacts and generates a large amount of heat; secondly, poor contact between the anode and cathode plates and the busbar generates heat; and thirdly, short circuits in the anode and cathode plates caused by the production process generate heat, leading to an increase in the solution temperature inside the electrolytic cell. High temperatures can damage the electrolytic cell. Data analysis can also help determine the operating status of the electrolytic cell. Therefore, it is necessary to monitor the temperature of the electrolytic cell and promptly investigate and address any instances of excessively high temperatures.

[0003] Currently, the electrolysis industry mainly relies on manual temperature measurement, which suffers from low efficiency, data lag, and high labor intensity. Although infrared thermal imaging and fiber optic temperature measurement technologies are gradually being applied, they still have the following drawbacks: Infrared thermal imaging: can only detect the surface temperature of the electrolytic cell and cannot reflect changes in the internal solution temperature; Fiber optic temperature measurement: It needs to be laid at the bottom of the electrolytic cell, which is easy to damage during construction, has insufficient corrosion resistance, high cost and difficult maintenance. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a mounting and fixing device for a nickel electrolysis cell solution temperature detection sensor.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A mounting and fixing device for a nickel electrolytic cell solution temperature detection sensor includes: The mounting bracket is set at the edge of the electrolytic cell; A temperature sensor is installed inside the electrolytic cell and mounted on a mounting bracket, with its probe vertically immersed in the electrolyte. The wire protection tube, installed on the mounting bracket, is used to thread the wires of the temperature sensor through and serves to protect the wires. The wires are connected to an external monitoring system.

[0006] The conductor protection tube is made of corrosion-resistant titanium.

[0007] The temperature sensor is mounted on the mounting bracket using a fixed support.

[0008] The mounting bracket includes: U-shaped clamps are used to hold the electrolytic cell at its edge. The set screw, threaded onto a screw hole on the side wall of the U-shaped clamp, is used to adjust the clamping tightness of the U-shaped clamp.

[0009] The set screw is made of titanium; the U-shaped clamp is made of corrosion-resistant titanium.

[0010] The beneficial effects of this utility model are: 1. Corrosion resistance: Made of corrosion-resistant titanium and polytetrafluoroethylene, it is suitable for the highly corrosive environment of electrolytes; 2. Secure installation: The U-shaped clamp and set screw work together to adapt to different tank thicknesses, ensuring the sensor position is fixed; 3. Easy maintenance: Modular design allows for sensor disassembly and replacement without interrupting the operation of the electrolytic cell; 4. Online monitoring: Enables real-time data acquisition of electrolyte temperature, improving production safety and efficiency. Attached Figure Description
