FILTER FOR FIBROUS SUSPENSIONS

摘要

A rotary filter (1) for fibrous suspensions (S) is disclosed comprising a rotor (2) coaxially arranged inside a filtering basket (4), an annular hollow space (8) being defined between them. In th eannular hollow space (8) there are one or more wing profiles (15) fixed to the outer lateral surface (2a) of the rotor (2) extending in an axial direction along the rotor (2). The outer surface 816) of each wing profile (15) facing the filtering basket has one or more discontinuity zones (16b, 16d) whose points have an increasing distance from the longitudinal axis (3) of the rotor (2) when running on the outer surface (16) of said wing profile (15) in a direction opposite to the rotation direction (V) of the rotor (2).
