ROTIERENDE TROMMEL ZUR BEHANDLUNG VON FASERSTOFF (Deutsch)

Freier Zugriff

The invention relates to a rotating drum (4) for treating fibrous material (1), the axis of rotation (2) of said drum being tilted by at most 30° with respect to the horizontal, comprising a sorting zone (3), into which fibrous material (1) mixed with water is fed and in which the drum (4) is perforated, wherein a fine fraction flows through the perforation (5) and a coarse fraction is repelled by the perforation, and wherein a cleaning device arranged outside of the drum (4) is associated with the perforation (5). In this case, the expenditure for keeping clear the perforation (5) shall be reduced by virtue of the fact that the cleaning device is formed by at least one spray pipe (6) having a plurality of nozzle openings (7), the nozzle openings (7) directing a respective water jet (8) onto a reflector (9) which reflects the water jet (8) to the perforated outer wall of the drum (4).
