DEVICE FOR DEWATERING OR WASHING AND DEWATERING SUSPENSIONS

摘要

A device for dewatering and/or washing suspensions, in particular suspensions of fibrous materials, has two dewatering rollers (5, 6) that turn in opposite directions and at least two other guiding rollers (7, 8), in particular pressrollers. Each endless screen of a pair of endless sieve or filter screens (9, 10) is guided over a dewatering roller and a guiding roller. The suspension to be dewatered or washed flows through the gap between both screens and is dewatered therein. The device is mainly characterised in that the gap between both screens is vertical and in that screen guiding means (15) are provided in the area of said vertical gap.
