A washing arrangement for washing and dewatering cellulose pulp, comprising a rotary drum (1) with a plurality of external compartments (2) on the drum for the pulp to be washed, which compartments are defined by axial compartment walls (3) distributed along the circumference of the drum, a stationary cylindric casing (4) enclosing the drum, whereby a ring-shaped space is defined between the casing and the drum, and where the ring-shaped space by means of longitudinal seals in the axial direction of the drum is divided into a forming zone for forming the pulp in the compartments of the drum, at least one washing zone for washing the pulp at overpressure, and a discharge zone for discharging the washed pulp, and where the longitudinal axial seals are attached to positioning cylinders for adjusting the radial position of the seals, where every longitudinal seal is articulated connected with the positioning cylinders to make possible oblique positioning of the seal.
Système de lavage et de déshydratation de pâte à papier, comprenant : tambour rotatif (1) à plusieurs compartiments externes (2) sur le tambour pour la pâte à laver, lesquels sont définis par des parois de compartiment axiales (3) réparties le long de la circonférence du tambour, boîtier cylindrique stationnaire (4) entourant le tambour, ce qui permet de définir un espace annulaire entre le boîtier et le tambour et de diviser cet espace par le biais de joints longitudinaux dans la direction axiale du tambour, ledit espace étant divisé en zone de formation de pâte dans les compartiments, au moins une zone de lavage de pâte en surpression, et une zone d'évacuation de pâte humidifiée, sachant que les joints considérés sont fixés à des cylindres de positionnement pour le réglage de leur position radiale, chaque joint étant articulé et relié aux cylindres pour permettre un positionnement oblique du joint.
