Abstract

The present invention provides a method and device for detecting attachments of steel claws on anode guide rods, collecting images of steel claws on anode guide rods, dividing the image information of each steel claw claw head, and using the image of each steel claw claw head as a detection area, and detecting each The image of the detection area is binarized; calculate the area of ​​each detection area after binarization processing, and compare the calculated area of ​​each detection area with the corresponding set area, if the area of ​​any detection area is larger than the corresponding When the setting area of ​​, it is judged that the steel claw attachment exceeds the allowable range. The invention can conveniently and accurately detect the content of attachments on steel claws, and judge whether the actual amount of attachments on steel claws meets the requirements of normal operation of the steel claws according to the maximum amount of attachments when the steel claws work normally, and the invention has simple structure and small amount of calculation , reliable performance, and high detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of anode conductive devices for electrolytic aluminum, and in particular relates to a method and a device for detecting attachments of steel claws of an anode guide rod. Background technique [0002] The anode for electrolytic aluminum is an important part of the electrolytic aluminum production system. It consists of anode guide rods, steel claws, explosive welding blocks, cast phosphorus iron, and anode carbon blocks. After long-term use, the anodes for electrolytic aluminum condense on the surface of steel claws and carbon blocks to form a hard shell of aluminum slag electrolyte combined with aluminum, sodium, potassium, calcium, magnesium, lithium, fluorine and other components, making it impossible to recycle. . For this reason, it is required to roughly clear more than 95% of the solidified electrolyte on the surface of the residual carbon block, and then finely clean a small amount of electrolyte att...
