Title:
MAGNETIC SEPARATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/072399
Kind Code:
A1
Abstract:
A simply constructed magnetic separation device. The magnetic separation device
(1) has an attraction treatment section (3) that vertically extends through
a bore (5a) of a superconducting magnet (5), has magnetic filters (9) that are
arranged in the attraction treatment section and sequentially conveyed upward,
and allows magnetic substances in a waste liquid to be attracted to the magnetic
filters (9); a filter return path (17) in which the magnetic filters (9), discharged
from the end point (3b) of the attraction treatment section (3) and returned again
to the start point (3a), are conveyed; a filter cleaning section (15) that cleans
the magnetic filters (9) between the attraction treatment section (3) and the
filter return path (17); and a first conveyance section (11) that conveys the
magnetic filters (9) from the attraction treatment section (3) through the filter
cleaning section (15) up to the filter return path (17). The first conveyance
section (11) conveys the magnetic filters (9) on a circular path in a horizontal
plane.
