Description

Fluid filter for ship

The present invention relates to a fluid filtration filter for ships, and more particularly to a fluid filtration filter for ships suitable for filtering foreign matter contained in various fluids required for the operation of the ship, such as sea water.

In general, various devices that use fluids, including ships, vehicles such as automobiles, power generation facilities, and the like, use a fluid filter for removing debris and sludge contained in the fluid. 1 and 2, a conventional fluid filter will be briefly described.

The fluid filter 1 shown in FIG. 1 includes a flat front part installed perpendicular to the flow direction of the fluid, and a semicircular part having a semicircle installed horizontally in the flow direction of the fluid. It has a form of wire mesh that can filter out debris and sludge contained in the fluid.

The fluid filter 1 is divided into a plurality of layers along a direction perpendicular to the flow direction of the fluid, and the plurality of layers are open portions A formed without a wire mesh, and a closed portion B with a wire mesh. Has a form listed alternately, the wire mesh by the semi-circular surface is present in the layer where the wire mesh by the front portion does not exist, and the wire mesh by the semicircular portion does not exist in the layer where the wire mesh by the front portion exists. It is formed so as not to.
