Abstract

The invention relates to an automatic desludging and refreshing apparatus of sensitive layer of metal sensor. Prior apparatus can not realize online automatic desludging and refreshing. A power output shaft of a motor in the invention penetrates vertical through a side wall of a detection pipe, end of which is fixedly connected with s bottom surface of a support plate. One end of a transmission shaft is fixedly connected with a top surface of the support plate. Side wall of the transmission shaft is provided with a limit pin. A shaft cover is sleeved out of the transmission shaft. A limit groove is arranged on inner wall of the shaft cover, along which the limit pin moves. A scraper blade is a vertical plate, bottom edge of which is fixedly connected with the top surface of the sleeve and top edge of which is in a blade shape and corresponds to sensitive layer position of the metal sensor. A spring is arranged between the scraper blade and the support plate. The invention is simple, practical, which can realize online automatic desludging and refreshing without damaging the sensitive layer of metal sensor.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to an automatic descaling and refreshing device for a sensitive layer of a metal sensor. Background technique [0002] In a large number of processes such as metallurgy, chemical industry, biomedicine, and environmental monitoring, it is often necessary to detect many important parameters such as conductivity, redox, hydrogen ion content, and carbon dioxide concentration. At present, it mainly relies on metal sensors such as zirconia, antimony, platinum, and alloys. detection. Its detection principle is to detect through the potential formed by the interaction or reaction between the ions contained in the detected substance and the ions in these metals. [0003] In the continuous detection of the above processes, the detected liquid will gradually accumulate on the surface of the metal electrode to form a layer of dirt, which will cause the sensor to fail to work norm...
