Device and method for positioning and detecting faulty plate of electrolyzer

Abstract

The invention relates to the technical field of image treatment, in particular to a faulted electrode plate positioning detection device for an electrolytic bath. The device comprises a thermal imager arranged above or obliquely above the electrolytic bath, wherein the thermal imager is used for acquiring an infrared thermal image of the electrolytic bath and outputting the infrared thermal image to a processing module; the processing module is used for processing the infrared thermal image to obtain the position of the electrode plate, with abnormal temperature, of the electrolytic bath. In addition, the invention further provides a corresponding detection method. According to the device, the process of acquiring the infrared thermal image of the electrolytic bath through the thermal imager, processing the infrared thermal image to obtain a pixel point with abnormal temperature and finally obtaining the corresponding electrode position is automatically carried out and a processing result is reliable; compared with manual detection, the efficiency and accuracy are greatly improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a device and method for detecting the location of a faulty plate in an electrolytic cell. Background technique [0002] Blister copper is pre-made into a thick plate as the anode, pure copper or stainless steel is made into thin sheets as the cathode, and a mixture of sulfuric acid and copper sulfate is used as the electrolyte. After electrification, copper dissolves from the anode into copper ions and moves to the cathode. After reaching the cathode, electrons are obtained and pure copper is precipitated at the cathode. Impurities in blister copper, such as iron and zinc, which are more active than copper, will dissolve into ions together with copper. Since these ions are not easy to precipitate compared with copper ions, the precipitation of these ions on the anode can be avoided as long as the potential difference is properly adjusted during electrolysis. The high-q...

Problems solved by technology

This detection method has the following disadvantages: first, it is time-consuming, laborious and inefficient, and the larger the scale, the more obvious the disadvantages; second, the detection lags behind. When manual detection is used in sequence, it takes a certain amount of time to complete a detection cycle, which cannot guarantee timely detection. Third, the accuracy and reliability of manual detection cannot be guaranteed
