Abstract
PURPOSE: To eliminate the need for preliminary concentration by another device by providing a sludge supply port in the intermediate part in a longitudinal direction and forming a preliminary concentrating part on the opposite side of a discharge port in a screw press type dehydrator for sludge dehydration.
CONSTITUTION: With this dehydrator, a circular conical screw shaft 5 projected with screw vanes 4 on the outside circumference is rotated by a driving shaft 7 and a driving device 8 in an outside cylinder 3 of a cylindrical filter medium provided with a sludge supply port 1 of a sludge hopper 2 and a cake discharge port 6. Here, (a) is a preliminary concentrating part, (b) is a sludge feed part, and (c) is a compression dehydration part. The sludge charged into the hopper 2 accumulates in the annular clearances formed by the shaft 5 and the vanes 4, and flows out gradually to the port 6 side and the beginning end part 9 side. The former compressed and is discharged as cake while filtrate is discharged from the cylinder 3. On the other hand, the former is discharged of filtrate from the cylinder 3 and is concd., is fed to the port 6 side and passes again through the lower part of the hopper 2. The sludge of the portion discharged in the part (a) flows into the part (a). In this way, the concd. sludge is fed to the part (c).
