Abstract

L’invention concerne un dispositif permettant d’éliminer des résidus de la surface d’une bande transportée à partir d’une installation de traitement de bande dans une direction d’avance, au moyen d’un jet de liquide ou de mélange de solides et de liquides qui est orienté sur la bande mobile. Le dispositif d’élimination de résidus comprend au moins une buse de sortie présentant un orifice de sortie par lequel sort le jet de liquide ou de mélange de solides et de liquides. L’invention vise à améliorer l’effet de nettoyage et à réduire les quantités de liquide nécessaires. A cet effet, l’étendue la plus longue de chaque buse de sortie est inférieure à la largeur de la bande et le dispositif présente des moyens permettant de déplacer chaque buse de sortie de manière angulaire par rapport à la direction d’avance de la bande, la vitesse de chaque buse de sortie étant supérieure à la vitesse de la bande.
