Abstract

A cylindrical filtration filter includes a cylindrical filter main body. The filter main body is constituted by at least two split filters. Each of the split filters has an arc shape in cross section. Each of the split filters includes a filter element for filtration and side frame bodies provided along side portions of the filter element. The side frame body of one of the two split filters adjacent to each other includes a first facing surface having an uneven shape. The side frame body of the other split filter includes a second facing surface having an uneven shape complementary to the first facing surface. The first facing surface and the second facing surface are fitted to each other when the filter main body is assembled.

First claim

What is claimed is:

1. A cylindrical filtration filter comprising:
a cylindrical filter main body constituted by at least two split filters each having an arc shape in cross section, each of the at least two split filters including:
a filter element for filtration; and
side frame bodies provided along side portions of the filter element,

wherein:
the side frame body of one of two split filters adjacent to each other among the at least two split filters includes a first facing surface having an uneven shape and the side frame body of the other of the two split filters includes a second facing surface having an uneven shape complementary to the first facing surface; and
the first facing surface and the second facing surface are fitted to each other when the filter main body is assembled.

2. The cylindrical filtration filter according to claim 1 , wherein:
the first facing surface of one of the two split filters includes an inward facing surface part facing an inside of one of the two split filters;
the second facing surface of the other of the two split filters includes an outward facing surface part facing an outside of the other of the two split filters; and
the first facing surface and the second facing surface are fitted to each other such that the inward facing surface part and the outward facing surface part are in contact with each other.

3. The cylindrical filtration filter according to claim 2 , further comprising a fastener provided along an outer peripheral surface of the filter main body, wherein the inward facing surface part and the outward facing surface part are brought into pressure contact with each other as a result of fastening by the fastener.

4. The cylindrical filtration filter according to claim 3 , wherein the fastener is a hose band or a wire band.

5. The cylindrical filtration filter according to claim 1 , wherein the filter element is a wire screen.
