Abstract

La présente invention concerne un dispositif, un appareil et un procédé pour nettoyer des filtres pour matières plastiques, en particulier des masses polymères recyclées. Plus spécifiquement, l'invention concerne un dispositif de filtrage comprenant un élément de base fixe et un filtre reçu dans un corps coulissant dans l'élément de base. L'élément de base fournit une position de filtrage et une position de nettoyage de filtre. Dans la position de filtrage, un tuyau pour transporter jusqu'au filtre la matière devant être filtrée et un tuyau pour retirer du filtre la matière filtrée sont présents, alors que dans la position de nettoyage de filtre, se trouvent des moyens de nettoyage pour transporter un écoulement de matière filtrée, sous pression, à travers ledit filtre dans une direction opposée à la direction de filtrage. Lesdits moyens de nettoyage sont externes à l'élément de base et lui sont reliés dans ladite position de nettoyage.
