Document Type and Number:
Japanese Patent JP2015134316
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a screw type solid-liquid separation apparatus which incorporates a flocculating/mixing device and thereby needing no arrangement of a flocculating/mixing tank at the preceding stage of the solid-liquid separation apparatus.SOLUTION: The screw type solid-liquid separation apparatus incorporating a flocculating/mixing device is provided in which an outer cylindrical screen 1 supported by front and rear frames 4 and 6 and a screw shaft 2 form a filtering chamber 21, and which conducts solid-liquid separation while transferring a flocculated sludge by a screw blade 11 wound on the screw shaft 2. The screw type solid-liquid separation apparatus incorporating the flocculating/mixing device include: a connection tube 3 feeding the sludge to the front end of the screw shaft 2; a feeding path 9 formed inside the screw shaft 2; a feeding hole 10 opened at the rear end of the screw shaft 2; a discharge port 12 formed at the front end side of the screw shaft 2; and an agitation device 14 arranged in the feeding path 9. Flocculated flock can be formed inside the screw shaft.
