FILTRATION DEVICE

摘要

[Issue] Suction pipes with simple structure holds adjacent sheet-shaped hollow filtering elements spaced at a constant interval from each other. [Means for Solution] 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.
