ABSTRACT:
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.
