摘要： Apparatus is disclosed for dewatering pulp suspensions including a pair of cylindrical rotatable liquid-premeable press rolls forming a nip therebetween, so that the material suspension can pass between the nip to be dewatered and to form a material web, a pair of doctor blades disposed below the nip, each associated with one of the press rolls for removing the material web therefrom, and a sealed casing enclosing at least the upper portion of the pair of press rolls, the sealed casing including an inlet for the material suspension, and the pair of doctor blades being coupled together so that they are movable relative to the nip in order to alter the distance between the pair of doctor blades and the nip when the size of the nip is adjusted.

摘要： Apparatus for liquid treatment and dewatering of material suspensions is disclosed including a pair of rotatable liquid permeable press rolls within a vat and in which the vat includes a bottom defining the space directed towards the nip between the press rolls and the remaining portion of the vat, and seals between the portions of the vat including a shoulder extending towards the bottom portion of the vat and an adjustable bar extending towards the remaining portion of the vat so the position of the bottom of the vat and the converging space in the direction towards the nip between the press rolls can be determined thereby.

摘要： Apparatus for dewatering material suspensions is disclosed including a pair of rotatable cylindrical liquid permeable press rolls at least partially immersed in a vat, inlet channels for supplying the material suspension to the bottom portion of the vat, transverse distribution pipes for distributing the material suspension to the inlet channels, and a central pipe for supplying the material suspension to the transverse distribution pipes, the central pipe including an adjustable outer sleeve axially adjustable therealong and connected to an openable portion at the bottom of the vat so that the adjustable outer sleeve and the openable portion of the vat can be adjusted between an upper closed position for normal operation of the apparatus and a lower open position in which access is provided to the space between the press rolls and the bottom of the vat, the central pipe including apertures so that when the adjustable outer sleeve and the openable portion of the vat are in the upper closed position, the apertures provide communication between the central pipe and the transverse distribution pipes.
