Title
(EN) METHOD AND APPARATUS FOR CLEANING OF CARBON ANODES
(FR) PROCÉDÉ ET APPAREIL DE NETTOYAGE D'ANODES DE CARBONE
Abstract
(EN) 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.
(FR) L'invention concerne un système et un procédé de post-nettoyage d'un électrolyte à partir d'une anode de carbone usée dans une production d'aluminium. Le système comprenant un robot ayant un bras manipulateur doté d'un outil pour le retrait de l'électrolyte; un système de vision comprenant au moins un capteur 3D pour la détection d'une forme 3D d'une surface de ladite anode de carbone et un système d'analyse pour identifier l'électrolyte sur ladite anode de carbone à partir de la forme 3D de la surface. Un capteur détecte la percée de l'outil dans l'électrolyte sur ladite anode de carbone et un système de commande commande le bras manipulateur du robot et l'outil sur la base des informations provenant du système de vision et du dispositif de capteur pour la détection de la percée de l'outil.
