Aluminum electrolytic cell cathode temperature-measuring sensor and mounting and using method thereof

Abstract

The invention discloses an aluminum electrolytic cell cathode temperature-measuring sensor. The aluminum electrolytic cell cathode temperature-measuring sensor comprises a mounting cross bar component, an electrical box and two temperature probe sets; the mounting cross bar component comprises a square tube and a grooved bar, and two ends of each of the square tube and the grooved bar are fitted with high-elastic spring clamps; each temperature probe set includes an insulation tube, a high-temperature protective tube and a long guide tube, a radiating tube is mounted at the connection of the high-temperature protective tube with the long guide tube, a radiating rod is mounted in the radiating tube, the insulation tube is filled with high-temperature-resistant insulation wool, the upper end of the high-temperature protective tube is inserted into the high-temperature-resistant insulation wool, a thermocouple is fitted in the top of the high-temperature protective tube, a high-temperature-resistant protective sleeve sleeves the thermocouple, a heat transfer rod and an insulating heat-isolating washer are mounted in the high-temperature protective tube, the lower end of the radiating rod and the upper end of the heat transfer rod are mounted in staggered manner, and a power generator sheet is mounted at the staggered part of the heat transfer rod and the radiating rod. The aluminum electrolytic cell cathode temperature-measuring sensor applicable to high-temperature environments and can generate a temperature gradient in the temperature probe sets, current may be generated by the power generator sheet through temperature differences, electricity is maintained and supplemented for circuitry, the aluminum electrolytic cell cathode temperature-measuring sensor is free of maintenance for a lifetime and is quick to mount.

Description

technical field [0001] The invention relates to a wireless temperature detection device, in particular to a cathode temperature measurement sensor of an aluminum electrolytic cell and an installation and use method thereof. Background technique [0002] The existing wireless temperature monitoring device used to measure the temperature of the cathode of an aluminum electrolytic cell requires battery power. When the ambient temperature reaches 80 degrees or more, the self-discharge of the battery will increase exponentially, so the battery life will only be half of the original life. One or lower, the life of the product will be reduced, and the product using wiring power supply, the cost of wiring and maintenance is relatively high. Contents of the invention [0003] In order to solve the defects and deficiencies in the above-mentioned prior art, the present invention provides a method suitable for high-temperature environments, which can detect the temperature of the cath...
