Title (EN) ROTATING DRUM FOR TREATING FIBROUS MATERIAL
(FR) TAMBOUR ROTATIF POUR LE TRAITEMENT DE MATIÈRE FIBREUSE
(DE) ROTIERENDE TROMMEL ZUR BEHANDLUNG VON FASERSTOFF
Abstract:
(EN) The invention relates to a rotating drum (1) for treating fibrous material (2), the rotational axis (3) of which drum (1) is inclined by at most 30° with respect to the horizontal, into which drum (1) fibrous material (2) which is mixed with water is fed on a first end side (4), which fibrous material (2) is transported within the drum (1) from the first (4) to the second end side (5) by means of transport elements (6), wherein the drum (1) is perforated, and a fine fraction flows through the perforation and a coarse fraction is repelled by said perforation. The treatment of the fibrous material is intensified by virtue of the fact that the first end side (4) of the drum (1) is closed and at least one retaining nozzle (9) directs a water jet onto the fibrous material (2) counter to the transport direction (10) of the fibrous material (2).
(FR) L'invention concerne un tambour rotatif (1) pour le traitement de matière fibreuse (2), dont l'axe de rotation (3) est incliné au maximum de 30° par rapport à l'horizontale, de la matière fibreuse (2) mélangée à de l'eau étant introduite dans le tambour au niveau d’un premier côté frontal (4), laquelle matière fibreuse (1) étant transporté par des éléments de transport (6) du premier (4) au deuxième côté frontal (5) dans le tambour (1). Le tambour (1) est perforé, une fraction fine traversant la perforation et une fraction grossière étant rejetée par la perforation. Selon l'invention, le traitement de la matière fibreuse doit être intensifié par le fait que le premier côté frontal (4) du tambour (1) est fermé et au moins une buse de retenue (9) dirige un jet d'eau sur la matière fibreuse (2) dans le sens opposé au sens de transport (10) de la matière fibreuse (2).
(DE) Die Erfindung betrifft eine rotierende Trommel (1) zur Behandlung von Faserstoff (2), deren Rotationsachse (3) höchstens 30° zur Horizontalen geneigt ist, in die an einer ersten Stirnseite (4) mit Wasser vermischter Faserstoff (2) zugeführt wird, welcher innerhalb der Trommel (1) mittels Transportelementen (6) von der ersten (4) zur zweiten Stirnseite (5) transportiert wird, wobei die Trommel (1) perforiert ist, eine Feinfraktion die Perforation durchströmt und eine Grobfraktion von dieser abgewiesen wird. Dabei soll die Behandlung des Faserstoffs dadurch intensiviert werden, dass die erste Stirnseite (4) der Trommel (1) verschlossen ist und zumindest eine Rückhalte-Düse (9) einen Wasserstrahl entgegen der Transportrichtung (10) des Faserstoffs (2) auf den Faserstoff (2) richtet.
