Abstract
Die Erfindung betrifft einen Sortierer (1) und ein Verfahrenzur Sichtung von Fasermasse. Der Sortierer umfasst eine Körperkonstruktion (2) und eine an deren Innenseite positionierte rotierbare Siebtrommel (3), deren mit Öffnungen (8) ausgerüstete Trommeloberfläche eine Sortierfläche (10) zur Sichtung der Fasermasse bildet. Zum Sortierer gehörenweiterhin eine Zuführkammer (6) und ein sich damit imZusammenhang befindliche Zuführblock (7) für die Fasermasse zum Zuführen der Fasermasse in den Sortierer, eine Akzeptkammer (9) und ein sich damit im Zusammenhang befindliche Akzeptblock (11) für die Fasermasse zum Entfernen einer durch die Sortierfläche (10) gelangten Fasermassenfraktion aus dem Sortierer sowie ein Rejektblock zum Entfernen einer nicht durch die Sortierfläche gelangenden Fasermassenfraktion aus dem Sortierer. Weiterhin umfasst der Sortierer zum Reinigen der Sortierfläche an der Siebtrommel mindestens eine statische Zuführöffnung (15) für ein Spülmedium zum Zuführen des Spülmediums aus der Akzeptkammer oder aus der Richtung der Akzeptkammer gegen die Siebtrommel oder in Richtung der Siebtrommel.The invention relates to a sorter (1) and a method for screening fiber material. The sorter comprises a body structure (2) and a rotatable screen drum (3) positioned on the inside thereof, the drum surface of which is equipped with openings (8) forming a sorting surface (10) for screening the fiber mass. The sorter further includes a feed chamber (6) and associated fiber feed block (7) for feeding the fiber mass into the sorter, an accept chamber (9) and an associated accept block (11) for removal of the fiber mass a fiber mass fraction from the sorter passing through the sorting surface (10) and a reject block for removing a fiber mass fraction not passing through the sorting surface from the sorter. Furthermore, the sorter for cleaning the sorting surface on the screen drum comprises at least one static feed opening (15) for a flushing medium for supplying the flushing medium from the accepting chamber or from the direction of the accepting chamber against the screening drum or in the direction of the screening drum.
