Abstract
A device for preventing re-wetting of thickened suspension in a filter of the type where a plurality of rotatable, axially spaced annular filter disks (3) are partially submerged in a container (1) for suspension, and where a collection trough (4) extends centrally through the filter disks (3) for collecting thickened suspension falling therefrom. Each filter disk comprises a plurality of filter sections (5) and each filter section is connected to a filtrate duct (7) situated at the circumference of the disk. At each filter disk (3) is arranged an arcuated channel (14) extending outside of the edges of the collection trough (4) such that filtrate flowing from a filter disk (3) is guided past the collection trough (4) and down into the suspension container (1).
