Abstract

L'invention se rapporte à un dispositif pour traiter les filtres usagés après leur utilisation en continu dans une machine de nettoyage à sec. A cet effet, plusieurs filtres usagés (1, 1, ...) sont enfermés et stockés en ordre sériel dans un réservoir sous pression (5), tandis qu'une source d'air pulsé (53), une source de refroidissement (54) pour la récupération du solvant et une source chauffante (55) sont disposées en un circuit de façon à relier une entrée d'admission d'air chaud (51) à une sortie d'émission d'air chaud (52) contenant le solvant dans le réservoir sous pression (5), et le solvant restant est transformé en gaz et récupéré par l'air chaud déchargé sur les surfaces périphériques externes des filtres usagés (1, 1, ...), pour que ceux-ci puissent être purifiés.
