Abstract
A debris filtration apparatus that includes a support unit including first to n-th unit supports arranged in a radial shape in a circumferential direction around a support housing disposed on an upper portion of a rotor unit configured to rotate at a predetermined speed in a chamber housing; a screen unit including first to n-th unit screens disposed between the first to n-th unit supports and configured to filter out debris from cooling water; and a bypass unit configured, when a load applied to the screen unit is increased to a predetermined level by debris deposited on the screen unit, to selectively rotate each of the first to n-th unit screens relative to the support unit and allow the cooling water to flow.
Claims19
A debris filtration apparatus comprising:
- a support unit including first to n-th unit supports arranged, to form a radial shape, in a circumferential direction around a support housing disposed on an upper portion of a rotor unit, the rotor unit being configured to rotate at a predetermined speed in a chamber housing;
- a screen unit including first to n-th unit screens disposed between adjacent ones of the first to n-th unit supports and configured to filter out debris from cooling water;
- and
- a bypass unit configured, when a load applied to the screen unit is increased to a predetermined level by debris deposited on the screen unit, to selectively rotate each of the first to n-th unit screens relative to the support unit and allow the cooling water to flow.

- and
- a bypass unit configured, when a load applied to the screen unit is increased to a predetermined level by debris deposited on the screen unit, to separately move each of the first to n-th unit screens toward an upper portion of the support housing and form a space for allowing the cooling water to flow therethrough.
