| 摘要 |
The invention relates to a washing arrangement (100) for washing and dewatering of cellulose pulp, comprising a rotatable drum (10) having a plurality of outer compartments (12) on the drum for the pulp to be washed, which compartments are defined by axial compartment walls (12b) distributed along the circumference of the drum, a stationary cylindrical casing (20) that encloses the drum, whereby an annular space (30) is defined between the casing and the drum and, where the annular space by longitudinal seals (40) in the axial direction of the drum is divided in zones (F, Tl, T2, U) for forming, washing and discharge of the pulp. The function of the longitudinal seals is optimized by units (60) for seal adjustment having measuring means for measuring a force acting on one of the longitudinal seals in direction from the drum and moving means for automatically moving the longitudinal seal substantially in the radial direction of the drum according to a predetermined pattern based on the measured force.
