Abstract

Procédé pour assurer le nettoyage, dans un dispositif de filtration, des ouvertures de la plaque filtrante, caractérisé en ce qu'il consiste à balayer la surface de la plaque à l'aide d'un système de pompe utilisant la force centrifuge de manière à établir une chute de pression locale sur la plaque dans la zone de ce système de pompe, la pression inférieure s'exerçant sur le côté de l'injection du matériau à filtrer et en ce que ledit système de pompe déplace le matériau enlevé des ouvertures du filtre vers les emplacements qui sont sensiblement éloignés de la plaque filtrante.
