Claims

[Claims for Utility Model Registration] A large number of rectangular filter papers that are continuous through folding ridges are erected between two parallel end plates, and the space occupied by these filter ends has a hollow cylindrical shape as a whole. A filter element that has a filter paper arrangement pattern that satisfies the following configurations (a) to (d). (b) Angle 2π/ with respect to the central axis of the hollow cylinder above
n (n is an integer of 6 or more) rotationally symmetric basic patterns are continuous. (b) The filter papers included in one basic pattern are arranged approximately parallel to each other at regular intervals. (c) The folding ridge lines on the outer circumferential side of the filter paper group are arranged at substantially equal pitches substantially along the outer circumferential circle. (d) The folding ridgeline on the inner circumference side of the filter paper group is arranged approximately along the tangent line between the n-divided inner circumferences, and the length of the filter paper group is formed so that it becomes shorter from one side to the other. ing.
