PURPOSE:To disperse pressure locally added to a separator and prevent breakage at the bottom of the separator, by making the width of feet provided at the bottom of a pole plate, shorter (smaller) than a size between separator ribs, and also making the length of feet shorter than the height of a rib. CONSTITUTION:The width of feet 3 provided at a pole plate 2 bottom portion contained in a baglike separator 1 is made shorter (smaller) than a size between separator 1 ribs 4, and also the length of these feet 3 is made shorter than the height of a rib 4. That is, if the width of a foot 3 is A, the length of the foot 3 is B, and the size between separator 1 ribs 4 is L, the height of a rib 4 is H, two expressions of A<L, B<H are simultaneously satisfied. As a result, feet 3 are floated by means of ribs 4 and the pole plate bottom portion comes into contact with all the ribs 4, and pressure is not added to the separator partially, so breakage at the separator bottom can be prevented. |
