Separable two-stage vertical suction cleaning apparatus and fiber disk filter including the same

A suction cleaning apparatus that is disposed between two adjacent disks (200a and 200b) configured in a fiber disk filter to suck and remove sludge collected in the filter cloth of the disks (200a and 200b), the suction cleaning apparatus comprising:

• a first suction holder (110) having a first suction port (111) for suctioning sludge, the first suction holder (110) disposed to have a structure in which the first suction port (111) faces the filter cloth of one of the two adjacent disks (200a and 200b);
• a second suction holder (120) having a second suction port (121) for suctioning sludge, the second suction holder (120) disposed to have a structure in which the second suction port (121) faces the filter cloth of the other one of the two adjacent disks (200a and 200b);
• a supporter (150) for supporting the first suction holder (110) and the second suction holder (120) in a horizontal position;
• a first link mechanism (130) connecting the first suction holder (110) located under the supporter (150) to the supporter (150) in a way that the first suction holder (110) can move in a direction close to or away from the filter cloth of the one of the two adjacent disks (200a and 200b);
• and
• a second link mechanism (140) connecting the second suction holder (120) located under the supporter (150) to the supporter (150) in a way that the second suction holder (120) disposed below the first suction holder (110) can move in a direction close to or away from the filter cloth of the other one of the two adjacent disks (200a and 200b).
