ARRANGEMENT FOR TREATMENT OF CELLULOSE PULP

摘要

The invention relates to a washing arrangement (200) for washing and dewatering of cellulose pulp, comprising a rotatable drum (202) with a plurality of outer compartments (204) on the drum for the pulp to be washed, which compartments are defined by axial compartment walls (204b) distributed along the circumference of the drum, a stationary cylindrical casing (208) that encloses the drum, whereby an annular space (210) is defined between the casing and the drum and where the annular space by means of longitudinal seals (212) in the axial direction of the drum is divided in zones (F, Tl, T2, U) for forming, washing and discharge of the pulp. At least two of the longitudinal seals are arranged such that they, when the drum rotates, meet compartment walls at shifted points in time with respect to each other. Preferably all of these longitudinal seals are arranged along the circumference of the drum at different positions with respect to respective opposite axial compartment walls.
