Japanese Patent JP5784841

Kind Code:

B2

Abstract:

The present invention relates to a device for filtering ballast water which performs filtering by installing a filter element having a conical shape in a concentric circle direction inside the device for filtering ballast water that accommodates a filter portion, and introducing ballast water from a lower end of the device for filtering and passing same through the filter element inside the device for filtering, and for discharging backwash water containing foreign substances that are inside a filter by means of differential pressure, which is created by a driving portion communicating with a filter element by rotating a suction portion that is located on a lower end of the device for filtering. In particular, the present invention relates to a high-efficiency candle-type device for filtering ballast water having a high-density filter structure, wherein the driving portion is positioned on a lower portion of a housing so that more filter elements can be accommodated inside the housing, thereby increasing filter efficiency so as to be appropriate for treating ballast water, the structure is simplified to reduce sealing cost and prevent original ballast water from mixing with filtered water, installation in a small space is possible, and wherein the device for filtering can be easily repaired.
