Title:
SQUEEZING ROLLER AND ROTARY DRUM-TYPE MAGNETIC SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2007/138891
Kind Code:
A1
Abstract:
This invention provides a rotary drum-type magnetic separator, which can satisfactorily
squeeze a liquid contained in sludge without striking the sludge into the squeezing
roller even when the sludge has such a shape that is likely to be striken into the
squeezing roller, and a squeezing roller for use in the separator. The separator
comprises a squeezing roller (6) which is abutted against a rotary drum (3) and
is rotated about a shaft substantially parallel to the rotating shaft of the rotary
drum (3). The rotary drum (3) has a built-in and fixed internal cylinder (5) on
which a plurality of magnets (4), (4), are disposed. An external cylinder (9)
formed of a nonmagnetic material is rotated on the circumference of the internal
cylinder (5). An elastic body is disposed on the squeezing roller (6) in its face
abutted against the rotary drum (3). The elastic body is formed of an uncrosslinked
polyurethane material composed mainly of a polyester polyol. A suppressing
member for suppressing the deformation of the elastic body is provided on both
ends of the squeezing roller (6).
