Description

Automatic treatment method and device for short-circuit cathode plate of electrolysis workshop Technical Field The invention relates to the technical field of automation of electrolysis equipment, in particular to an automatic treatment method and device for a short-circuit cathode plate of an electrolysis workshop. Background The electrolytic copper yield is mainly concentrated in China and copper resource countries, wherein the electrolytic copper yield in China occupies most proportion, according to Mysteel statistical data, the electrolytic copper yield in China in 2021 is 1048.7 ten thousand tons, 4.66% compared with 2020, and the electrolytic copper yield in 2022 is further increased to 1106 ten thousand tons and 5.46% compared with the same. Copper electrorefining was invented in Europe in 1865, which is significant for the progress of copper smelting technology. In 1979, the development of the ISA electrolytic refining process in Australia Tosvier was exceeded, and the application of a permanent cathode plate was opened. From this point, the automation of copper refining production is greatly promoted. Over time, modern electrolytic processes for mass production of cathode copper have been widely popularized worldwide, and more enterprises are adopting processes for mass production of cathode copper with permanent stainless steel cathode plates. In the current copper electrolysis industry, in order to improve the yield of cathode copper as much as possible, the interval between the anode and the cathode is generally about 100m, and in order to improve the yield of cathode copper, the interval between the anode and the cathode is generally about 100 mm. If particles, bulges, burrs and the like grow on the cathode, short circuit between the cathode and the anode can be caused.
