Disclosed is a mechanical filtering apparatus. The apparatus comprises a housing(1), an outside supporter(10), an inside supporter(20), a reduction gear(30), the 1st and 2nd filter pieces(40, 50). The housing(1) includes an inlet(2), a collector(3) and an outlet(4). The outside supporter(10) includes a supporting piece(11), a sealing piece(12) and an internal gear(13). The inside supporter(20) installed in the outside supporter(10) has a rotation speed higher than that of the outside supporter(10). The reduction gear(30) connected a drive gear(G) supplies a reduced torque to the internal gear(13). The 1st filter piece(40) is installed on the outside supporter(10) by a pin(P). The 2nd filter piece(50) is installed on the inside supporter(10) by a pin(P). The 1st and 2nd filter pieces(40, 50) are inserted together. Thereby, the filtering is performed in a state of rotating the 1st and 2nd filter pieces(40, 50), so that the filter pieces(40, 50) are used altogether.
