A filter assembly for removing filtrate from industrial process streams. The assembly includes a housing in which a filter element is disposed. The filter element has a surface against which the filtrate is trapped. A cleaning head to which cleaning blades are attached is disposed in the housing and removes the trapped filtrate. An actuator tube extends through the housing. Internal to the actuator tube is a first magnet. Pressurized gas is selectively applied to the ends of the actuator tube to move the first magnet in the tube. A second magnet is attached to the cleaning head. The second magnet is magnetically coupled to the first magnet so the second magnet moves with the first magnet. Thus, the movement of the first magnet is transferred by the second magnet to the clean head so the cleaning blades move against the filter element.
L'invention porte sur un ensemble de filtrage permettant d'extraire des éléments indésirés de flux de processus industriels. Ledit ensemble comporte une enceinte où sont placés: un élément filtrant à la surface duquel sont piégés les éléments indésirés; une tête de nettoyage, munie de lames racleuses, qui élimine les éléments indésirés piégés; un tube actionneur à l'intérieur duquel se trouve un premier aimant mobile qu'on peut déplacer en appliquant sélectivement du gaz sous pression aux extrémités dudit tube; et un deuxième aimant fixé à la tête de nettoyage, magnétiquement couplé au premier aimant, et se déplaçant avec lui. Ainsi, le mouvement du premier aimant, transmis à la tête de nettoyage par l'intermédiaire du deuxième aimant, déplace les lames racleuses à la surface de l'élément filtrant.
