Title:
FILTERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/013596
Kind Code:
A1
Abstract:
A filtering device (10) is provided with a filtering tank (11), a filtration element unit (12), a magnet (19), and a submerged air-discharging mechanism (50). The filtration element unit (12) has a large number of magnetic-grain filtration elements (31) which are metal spheres. When the magnet (19) is at a first position, the magnetic-grain filtration elements (31) are attracted to each other. When the magnet (19) moves to a second position, the magnetic attraction between the magnetic-grain filtration elements (31) is cancelled. To clean the magnetic-grain filtration elements (31), a cleaning liquid (Q2) located above the magnetic-grain filtration elements (31) is dropped through between the magnetic-grain filtration elements (31). In the cleaning of the magnetic-grain filtration elements (31), the submerged air-discharging mechanism (50) discharges air (57) into the cleaning liquid (Q2), which is located above the magnetic-grain filtration elements (31), toward the magnetic-grain filtration elements (31). The cleaning liquid (Q2), located above the magnetic-grain filtration elements (31), is urged toward the magnetic-grain filtration elements (31) and air bubbles are mixed in the cleaning liquid (Q2). The cleaning liquid (Q2) flows from above downward between the magnetic-grain filtration elements (31) to clean the elements (31).
