US 2012/0067809 A1 · FILTERING APPARATUS

Abstract

A filtering apparatus sucks liquid in hollow portions (10) of the elements (1) via suction pipes (3) so that liquid passes the elements (1) and is filtered. Each pipe (3) has suction holes (4) connected to the portions (10). The pipes (3) are inserted into through holes (2) of the elements (1). The elements (1) are arranged side by side and connected to the pipes (3). A ring-shaped packing (5) is interposed between the elements (1), and water-tightly seals the clearance between the element (1) and the pipe (3). The holes (2) are arranged at peripheral locations of each element (1). The pipes (3) are inserted into the holes (2) of each element (1). The elements (1) are held at the peripheral locations to the pipes (3).

A filtering apparatus comprising:

a plurality of sheet-shaped hollow filtering elements each of which includes two sheets of laminated filtering materials with the outer peripheral edge parts of the filtering materials being bonded to each other;
and
suction pipes that penetrate the plurality of sheet-shaped hollow filtering elements to be connected to hollow portions of the sheet-shaped hollow filtering elements, wherein
liquid passes the hollow portion inside said sheet-shaped hollow filtering element from the outside of said sheet-shaped hollow filtering element, and moves from the hollow portion of the sheet-shaped hollow filtering element to said suction pipes so that the liquid is filtered, wherein
each of said suction pipes has suction holes to be connected to the hollow portions of said sheet-shaped hollow filtering elements, wherein
said sheet-shaped hollow filtering elements have through holes that receive the suction pipes, and the suction pipes are inserted into the through holes so that the plurality of sheet-shaped hollow filtering elements are arranged side by side and are connected to the suction pipes, wherein
ring-shaped packing members are interposed between the sheet-shaped hollow filtering elements that receive the suction pipe and are arranged side by side to water-tightly seal the clearance between the sheet-shaped hollow filtering element and the suction pipe, and each of the ring-shaped packing members has an outer shape larger than the inner shape of the through hole of the sheet-shaped hollow filtering element to be inserted into the suction pipe, and wherein
the through holes are arranged at a plurality of locations along the outer peripheral part of each of said sheet-shaped hollow filtering elements, and said suction pipes are inserted into the through holes of each of said sheet-shaped hollow filtering elements so that each of said plurality of sheet-shaped hollow filtering elements are held at the plurality of outer peripheral locations to said suction pipes.
