Title:
SOLID-LIQUID SEPARATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/135920
Kind Code:
A1
Abstract:
[PROBLEMS] A solid-liquid separation device having a solid-liquid separation section
provided with adjacent stationary plates and movable plates arranged between
the adjacent stationary plates and also having at least one screw extending so
as to penetrate the solid-liquid separation section. The movable plates are
formed such that they are pushed and moved by the screw that rotates.An object to
be processed having entered in the solid-liquid separation section is moved toward
the exit of the solid-liquid separation section, and at the same time, filtrate
separated from the object is discharged to the outside through a filtrate discharge
gap of the solid-liquid separation section. Wear of the movable plates are suppressed
with dewatering efficiency for slurry maintained at a high level. [MEANS FOR
SOLVING PROBLEMS] The diameter (d) of the shaft (41) of a screw section (21A)
on the exit side of the solid-liquid separation section (3) gradually increases from
a predetermined position (S1) of the screw in the solid-liquid separation
section (3) toward the exit side, and the lead angle of the screw section (21A)
is set to the range from 10˚ to 30˚.
