摘要： 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 (8) 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 feeding out the washed pulp, and where the filtrates from different washing stages are collected in a peripheral valve located at the end wall of the drum, where the filtrate stages are separated by seals in the valve, where at least some of the valve seals in the peripheral valve are displaced in relation to the corresponding longitudinal seal, seen in the rotation direction of the drum.

摘要： The invention relates to a n arrangement (100) for washing and dewatering cellulose pulp comprising: a press roll (102), which is arranged to rotate during operation and which has a perforated outer surface (104) for dewatering the pulp; a stationary guide surface (106), arranged at a distance from the perforated outer surface (104) of the press roll so as to enclose the press roll (102) in the circumferential direction, such that a substantially closed vat (107) is defined between stationary guide surface (106) and the press roll (102); a pulp passage (108), being provided in said vat (107) between the perforated outer surface (104) of the press roll (102) and its stationary guide surface (106), such that during operation, pulp that is fed into the vat (107) is transported in a direction of rotation and, at the end of the pulp passage, is pressed in a pinch (110), possibly between the press roll and a second press roll. A radial distance (D) between the stationary guide surface (106) and the associated press roll (102) is generally increasing towards the pinch (110), such that the vat (107) diverges, towards the pinch (110).

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.

摘要： An arrangement (100) for washing cellulose pulp, comprising a pulp transport rotor (10) and a number of pulp chambers (12), is provided. Each pulp chamber is partly defined by a perforated surface (12a) of the rotor. The rotor is arranged to rotate stepwise so as to transfer the perforated surface of the respective pulp chambers between different pulp handling zones (Z1, Z2, Z3, Z4). The washing arrangement further comprises a piston device (20) arranged at one pulp handling zone, said piston device being arranged for piston movement (M) in a radial direction so as to, in operation and upon movement towards the pulp, increase the consistency of pulp, and means for displacement washing of the pulp with increased consistency using the piston device.
