Device for measuring electrolyte temperature online

Abstract

The present invention relates to a device for measuring temperature online, in particular to a device for intermittently measuring electrolyte temperature online. According to the device for measuringelectrolyte temperature online, an air cylinder is placed obliquely inside girders at the upper part of the device; the air cylinder is connected with the top of a measuring hammer rod; a thermocouple is arranged in the measuring hammer rod; the thermocouple is sleeved with a ceramic sleeve; the thermocouple and the ceramic sleeve protrude out from the bottom of the measuring hammer rod; and thethermocouple is connected with a voltage measuring device. The device of the invention has the advantages of portability, convenience in installation, convenience in disassembly, low maintenance rateand convenient and quick operation. With the device adopted, electrolyte temperature data can be accurately measured, and the high stability of measurement can be ensured.

Description

technical field [0001] The invention relates to a device for measuring temperature on-line, in particular to a device for intermittently measuring electrolyte temperature on-line. Background technique [0002] The electrolytic aluminum industry is a traditional process industry. Compared with steel, chemical and other industries, there is still a big gap in the level of informatization and automation. At present, a large number of process technical parameters are obtained through manual measurement and sampling analysis. The detection and data entry consume a lot of manpower and physics, and the information feedback lags behind. Only two signals of voltage and current are used for the production control of the electrolyzer. The control level Low; production operations and management only use a limited amount of real-time measurement data, and cannot grasp the real state of the electrolytic cell in a timely and comprehensive manner to achieve accurate control of the electroly...

Problems solved by technology

At present, a large number of process technical parameters are obtained through manual measurement and sampling analysis. The detection and data entry consume a lot of manpower and physics, and the information feedback lags behind. Only two signals of voltage and current are used for the production control of the electrolyzer. The control level Low; production operations and management only use a limited amount of real-time measurement data, and cannot grasp the real state of the electrolytic cell in a timely and comprehensive manner to achieve accurate control of the electrolytic cell

Due to the lack of real-time online detection, analysis and processing of key data, the lack of control over the state of the electrolyzer during the actual production process of the electrolyzer, the lack of combination of production management and design, and the lack of an accurate grasp of the thermal balance state, the electrolyzer is difficult To achieve "transparent management" and long-term stable operation, relying too much on the experience and knowledge of technicians, resulting in great differences in the technical conditions and technical indicators of the same electrolyzer technology in different enterprises
