Document Type and Number:
Japanese Patent JP5191565
Kind Code:
B2
Abstract:
A straight-drum centrifugal dehydration device, wherein extraction of moisture from heavy phase built up in a bowl is facilitated to improve the dehydration effect, and compression efficiency is improved to achieve a reduced load. The straight-drum centrifugal dehydration device, wherein an outer peripheral surface of a rotary drum (21) of a screw conveyor (20) comprises a straight section (24) and a tapered section (25) that spreads outward and away from the straight section, the straight-drum centrifugal dehydration device having an inorganic flocculant feed path for feeding an inorganic flocculant to an inner peripheral surface of the straight section (24) of the rotary drum, and the straight section being provided with an inorganic flocculant addition nozzle (109) communicating with the inorganic flocculant feed path and projecting into an annular space of the bowl and an orifice (108) for adding the inorganic flocculant.
