Method and device for detecting deformation of steel claw of anode guide rod

Abstract

The invention provides a method and device for detecting the deformation of steel claws of an anode guide rod, which collects images of steel claws of an anode guide rod, divides the image information of each steel claw claw head, uses the image of each steel claw claw head as a detection area, and performs each detection Binarize the image of the area; calculate the horizontal span value of each steel claw head in the direction of steel claw arrangement according to the result of binarization processing, if the horizontal span value of any steel claw head is greater than the corresponding set When the value is fixed, it is judged that the steel claw is deformed. The invention can conveniently and accurately detect whether the steel claw is deformed, and judge whether the actual deformation of the steel claw meets the requirement of the normal work of the steel claw according to the maximum deformation amount of the steel claw during normal operation. The invention has the advantages of simple structure, 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 deformation of a steel claw 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. In the production of electrolytic aluminum, the lower part of the anode carbon block needs to be immersed in the high-temperature electrolyte in the molten state in the electrolytic cell. With the continuous consumption of the anode carbon block, the entire anode also needs to move down continuously. The temperature increases accordingly. When the anode carbon block is consumed to the specified remaining thickness, the entire anode needs to be taken out of the electrolytic cell, after cooli...
