Abstract

PURPOSE:To make repetition of filtering-backwashing easily and enhance filtering accuracy by providing a filter covered the first freely expandable coil with fibers, and opening a slit section of the filter by means of the second freely expandable coil at the backwashing. CONSTITUTION:The first expandable coil 5, hanging down in the central section in the vertical direction of an outer cylinder 1 with an introducing section 14 installed on an opening section 15 of a cylinder 9 at the upper section and with a blocking plate blocking the filter at its lower section, is covered with fibers 16 and energized downward. Also, the second expandable coil 7 contacted to a fixed plate 12 at its lower end is fixed on the back of the blocking plate 6 at its upper end, and the fixed plate 12 and the introducing section 14 are fixed with a guide rod 8 through a blocking plate 6. The second expandable coil 7 is energized toward the blocking plate 6.
