Definitions

  • the compartments of the middle portion of the container are closable at the upper as well as the lower end by means of plates having sectorshaped openings therein, which plates are turnable by means of a common central shaft, the sector-shaped openings being mutually coextensive and arranged so as to admit during the rotation of the plates, a flow of pulp through one compartment or a small number of compartments while the plates close a successively changing series of the compartments, the closed compartments at any given time comprising the majority of the compartments in the container.
  • the container is divided up over the greater part of its length into 12 equal compartments.
  • These partitions are inserted between and attached to the cylindrical shell of the container and a central tube 42 which surrounds the shaft 21.
  • the upper and lower edges of the partitions are horizontal and are situated in the same plane.
