Rare earth molten salt electrolytic cell temperature detection device and system

Abstract

The invention discloses a rare earth molten salt electrolytic cell temperature detection device and a rare earth molten salt electrolytic cell temperature detection system. The rare earth molten saltelectrolytic cell temperature detection device comprises a fixing device, a rotating groove, a horizontal telescopic mechanical arm, a vertical telescopic mechanical arm, a thermocouple and a sleeve,wherein the rotating groove is formed in the upper end of the fixing device; the horizontal telescopic mechanical arm is clamped in the rotary groove, and one end, away from the rotary groove, of thehorizontal telescopic mechanical arm is connected with the vertical telescopic mechanical arm; the sleeve is fixed at the lower end of the vertical telescopic mechanical arm; and the thermocouple is welded in the sleeve. The rare earth molten salt electrolytic cell temperature detection device and the rare earth molten salt electrolytic cell temperature detection system can detect the temperatureof molten salt at any part in an electrolytic cell in the rare earth electrolysis process.

Description

technical field [0001] The invention relates to the field of remote temperature detection of an electrolytic production process, in particular to a temperature detection system for a rare earth molten salt electrolytic cell. Background technique [0002] Rare earth has excellent optical, electromagnetic and other physical properties, and is an indispensable key element for transforming traditional industries, developing emerging industries and national defense technology industry. Rare earth has become one of the country's strategic resources. The production of rare earth metals consumes a lot of energy, and the degree of mechanical automation in the production process is low. The production of rare earth metals is still done manually, and the production process relies on the experience of electrolyzers to operate. As a result, the production of rare earth metals is greatly affected by human factors, and the product quality is not good. Stability seriously restricts the deve...

Problems solved by technology

[0005] Method 1: Use an infrared thermometer to measure, which can only measure the temperature on the surface of the molten salt, but cannot measure the temperature at the bottom of the tank or inside the molten salt; due to the fluorine-containing gas that is produced during the electrolysis of rare earth molten salts and has a corrosion function, infrared measurement If the thermometer is placed above the electrolytic tank for a long time, the lens of the thermometer will be corroded;

[0006] Method 2: Put the temperature sensor thermocouple in a casing made of ceramic or other materials, and then fix it in the electrolytic molten salt for temperature measurement. The measured data will be displayed locally, and remote monitoring and display cannot be performed.
