Claims

[Claims for Utility Model Registration] A large number of rectangular filter papers that are continuous through a folding ridge line are two
A filter element in which the filter papers are vertically arranged densely between two parallel end plates, and the space occupied by these filter papers has a hollow cylindrical shape as a whole, and the arrangement pattern of the filter papers is under the following conditions (a). A filter element that satisfies ~(e). (b) ... Filter papers are arranged radially at angles α with respect to the center line of the hollow cylinder, and the inner folding ridge line a of the filter paper is located on the circumference of half iR1, and the outer folding edge line a is located on the circumference of half iR1, and The curved ridgeline b is located on the circumference of the radius R4. {mouth}...A rotationally symmetrical pattern with an angle extension of 2α with respect to the center line, where the angle 2α is the minimum repeating angle of the pattern. (C)... Two adjacent folding edges a are connected by two filter papers connected by a folding edge line C, and this folding edge line C is located on the circumference of a radius R3. (d)...The two adjacent folding edges b are aligned with two pieces of filter paper connected by the folding edge d, and this folding edge line d7 (located on the circumference of the radius R2) (e)...The above radii Rl, R2, R3, R4 are R1
The relationship is <R2<R3<R4.
