METHOD AND APPARATUS FOR CLEANING OF CARBON ANODES

摘要

A system and method for post-cleaning of electrolyte from a used carbon anode in aluminium production is described. The system comprising a robot with manipulator arm provided with a tool for removal of the electrolyte; a vision system comprising at least one 3D sensor for detection of a 3D shape of a surface of said carbon anode and an analysis system for identifying the electrolyte on said carbon anode from the 3D shape of the surface. A sensor detects tool breakthrough in the electrolyte on said carbon anode and a control system controls the robot manipulator arm and the tool based on information from the vision system and the sensor device for detection of tool breakthrough.
