[0037] According to the first link mechanism 130 configured in this way, the first suction holder 110 is separated from the filter cloth by its own weight when the suction cleaning of the filter cloth is not performed, but when the suction cleaning process is initiated, the first suction holder 110 adheres closely to the filter cloth due to the suction force formed in the first suction holder 110.

[0038] The second link mechanism 140 is configured to support the second suction holder 120 to move in a way that the second suction holder 120 can move in a direction close to or away from the filter cloth of the one of the two adjacent disks 200b. The second link mechanism 140 comprises a pair of second links 141, the upper end of the first link 141 being hinge-coupled to the supporter 150 and the lower end of the first link 141 being hinge-coupled to the upper part of the second suction holder 110.

[0039] The second link 141 according to a preferred embodiment of the present invention consists of a first vertical portion 1411, a horizontal portion 1412, and a second vertical portion 1413, having a two-stage bent shape with a first bent portion at the boundary of the first vertical portion 1411 and the horizontal portion 1412, and a second bent portion at the boundary of the horizontal portion 1412 and the second vertical portion 1413.

[0040] More specifically, the first vertical portion 1411 has a structure in which the upper part is hinged to the supporter 150 and extends from the supporter 150 to a height corresponding to the space between the first suction holder 110 and the second suction holder 120 through the space around the side portion of the first suction holder 110.

[0041] The horizontal portion 1412 extends in a horizontal direction from the lower portion of the first vertical portion 1411 and is protruded into the space between the first suction holder 110 and the second suction holder 120.

[0042] The second vertical portion 1413 extends from the end of the horizontal portion 1412 to the upper part of the second suction holder 120 to be hinge-coupled to the upper part of the second suction holder 120.

[0043] According to second link 141 configured in this way, a pair of second links 141 arranged in the left and right sides of the first suction holder 110 connect the supporter 150 and the second suction holder 120.

[0044] Like the first suction holder 110, the second suction holder 120 is separated from the filter cloth by its own weight when the suction cleaning of the filter cloth is not performed, but when the suction cleaning process is initiated, the second suction holder 120 adheres closely to the filter cloth due to the suction force formed in the second suction holder 120.

[0045] In a separable two-stage vertical suction cleaning apparatus according to the present invention configured as described above, the supporter 150 is composed of a hollow tube and is connected to the first suction holder 110 via the first flexible tube 151. Therefore, the sludge sucked from the filter cloth by the first suction holder 110 is discharged through the first flexible tube 151 and the supporter 150.

[0046] The supporter 150 is connected to the manifold 160 to discharge the sludge into the manifold 160.

[0047] Likewise, the second suction holder 120 is connected to the manifolder 160 via the second flexible tube 152, and the sludge sucked from the filter cloth by the second suction holder 120 is discharged to the manifold 160 through the second flexible tube 152.

[0048] Like the commonly used fiber disk filter, the fiber disk filter, including a separable two-stage vertical suction cleaning apparatus configured as described above, comprises a plurality of disks 200 having a plurality of sectorial shape filter segments 210 arranged in the circumferential direction on both sides. The plurality of disks 200 are installed on a rotating drum 300 at regular intervals in the longitudinal direction and the rotating drum 300 is installed in a structure forming a water tank or a water channel and is rotated by the driving unit 400 to filter the sludge in the inflow water.

[0049] The separable two-stage vertical suction cleaning apparatus 100 is installed to be located between the disk 200 and the disk 200 and the first suction holder 110 and the second suction holder 120 are arranged in an upper and lower two-stage structure so that the volume of the fiber disk filter and the area of the site required for the installation of the fiber disk filter can be significantly reduced.

[0050] The separable two-stage vertical suction cleaning apparatus 100 installed between the disks 200 implements an efficient suction washing environment while acting as follows.

[0051] The first suction holder 110 and the second suction holder 120, which constitute a separable two-stage vertical suction cleaning apparatus 100 according to the present invention, are kept apart from the filter cloth at normal times when the suction washing of the filter cloth is performed so that it is possible to prevent sludge collected in the filter cloth from being pressed and penetrated deep into the villi by the suction holder during the filtration process.

[0052] On the other hand, when the cleaning process to remove sludge collected on the filter cloth is initiated, the suction cleaning pump 500 connected to the manifold 160 is operated, and water in the manifold 160, in the supporter 150, and in the first and second suction holders 110 and 120 are discharged to the outside forming suction force in the first and second suction holders 110 and 120.
