Title (EN) FILTER FOR EXTRUDER PRESS
(FR) FILTRE POUR PRESSE EXTRUDEUSE
Abstract:
(EN) A solid/fluid separation module (300) and press comprises at least one filter unit (301) for a solid/fluid separating press having a barrel with a core opening (112) for at least one conveyor screw. The filter unit includes a pair of end plates (321,322) and a plurality of intermediate filter plates (314) placed one behind the other and sealingly compressed into a plate stack (310) between the end plates. Each intermediate plate (314) has at least one drainage perforation (362) separate from the core opening, the core opening and drainage perforation each extending from a front face to a back face of the intermediate filter plate. In the filter unit, all end plates and barrel plates are aligned such that the core openings form the core passage of the filter block and such that the drainage perforations form an internal fluid collection chamber (338) within the filter unit.
(FR) Selon l'invention, un module de séparation solide/fluide (300) et une presse comprennent au moins une unité de filtration (301) pour une presse de séparation solide/fluide pourvue d'un cylindre comportant une ouverture centrale (112) pour au moins une vis transporteuse. L'unité de filtre comprend une paire de plaques d'extrémité (321,22) et une pluralité de plaques de filtre intermédiaires (314) placées les unes derrière les autres et comprimées de façon étanche en une pile de plaques (310) entre les plaques d'extrémité. Chaque plaque intermédiaire (314) comporte au moins une perforation de drainage (362) séparée de l'ouverture centrale, cette dernière et la perforation de drainage s'étendant chacune d'une face avant à une face arrière de la plaque de filtre intermédiaire. Dans l'unité de filtre, toutes les plaques d'extrémité et les plaques de cylindre sont alignées de sorte que les ouvertures centrales forment le passage central du bloc filtre et de sorte que les perforations de drainage forment une chambre de collecte de fluide interne (338) à l'intérieur de l'unité de filtre.
