1. A filter cleaning apparatus for cleaning a roll-type filter, the apparatus comprising:
(i) a cleaning tank provided with a cavity for accommodating a cleaning solution; and
(ii) a frame that is separable from the cleaning tank and comprises a supporting portion for supporting weight of the roll-type filter and a fixed portion protruding from the supporting portion for fixing the roll-type filter,
wherein the supporting portion comprises a circular base having a plurality of through holes through which the cleaning solution passes, and a plurality of supporting members for partially supporting a lower portion of the roll-type filter,
the supporting members are separated from each other in a radial direction relative to the center of the circular base and protrude from the top surface of the circular base toward the roll-type filter, and each of the supporting members extends in a circumferential direction of the roll-type filter, and
the supporting members comprise at least one first supporting member extending along the circular base in a circumferential direction of the circular base and having a first radius from the center of the circular base, and at least one second supporting member extending along the circular base in a circumferential direction of the circular base and having a second radius from the center of the circular base, the second radius being larger than the first radius,
wherein at least one of the through holes is disposed between the at least one first supporting member and the at least one second supporting member.
