Abstract

A centrifugal cleaner for cleaning in particular a paper pulp suspension comprises an elongated centrifugal chamber 1 which is conically tapered towards the one end. At the wider end of the centrifugal chamber there is a tangentially directed inject inlet 2 for the suspension to be treated and at the narrower end of the centrifugal chamber a heavy-reject outlet 5 for heavier impurities in the treated suspension. At the wider end of the centrifugal chamber there is additionally a centrifugal finder tube 9, the outer end of which emerges into a circular-cylindrical chamber 10 which has a tangentially directed acceptance outlet 11 for the desired good fibres in the treated suspension. Intruding coaxially into the circular-cylindrical chamber 10 directly opposite the centrifugal finder tube 9 is a second tube 12. This second tube has its inner end located at an axial distance from the mouth of the centrifugal finder tube 9 and has at least at its inner end a greater diameter than the mouth of the centrifugal finder tube. This second tube serves as a light-reject outlet for lighter impurities and air in the treated suspension and is advantageously conically tapered in the direction away from its inner end. <IMAGE>
