Description

[0001] SEA WATER STRAINER FOR SHIP [0002]

The present invention relates to a seawater strainer for marine use, and more particularly, to a marine seawater strainer capable of overcoming the limitation of an installation space while maintaining its inherent function and being installed in a narrow area.

One side of the hull of the ship is equipped with a sea chest for taking seawater from the outside. The seawater flowing into the seawater inlet flows into the seawater pump of the ship through the sea water strainer, .

In this case, the foreign matter mixed with the seawater may cause equipment damage, breakdown, deterioration of the sterilization effect of the ballast water, and it is general to install the seawater strainer at the front of the seawater pump to remove the foreign substance first.

Conventionally, a seawater strainer for a marine vessel has a structure of a drum type body and a filter installed inside the body to filter various foreign substances in seawater.

However, in the case of such a drum type seawater strainer, since a bulky drum type body is to be connected to the pipeline through which seawater flows, it is necessary to secure a relatively wide separate installation space, There is a problem that can not be installed.

Hereinafter, a seawater strainer according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing a configuration of a sea water strainer for a ship according to an embodiment of the present invention; FIG. Fig. 2 is a cross-sectional view of each part of Fig. 1, wherein (a), (b) and (c) show cross sections of the "A" "B" "C"

The seawater strainer according to an embodiment of the present invention is a pipe type in contrast to a drum type that requires a large volume and a large installation space separate from the pipeline, A body 100 connecting between the outlet pipes 20 and a filter 200 installed in the body 100.

The seawater introduced into the inlet pipe 10 through a seawater inlet (not shown) of the ship is discharged through the outlet pipe 20 via the pipe-type body 100 provided with the filter 200.

The body 100 of the seawater strainer is formed as a pipe type so as to replace the role of a pipeline, and a filter 200 is provided in the body 100.

Accordingly, since the pipe-type body 100 plays the role of a pipeline, it is not necessary to add additional pipelines and a separate installation space for installing the seawater strainer is also unnecessary.

In one embodiment, the body 100 is configured to allow the inlet pipe 10 and the outlet pipe 20 to be vertically fastened to each other for space savings. The inlet pipe 10 and the outlet pipe 20 are installed in a direction perpendicular to each other with the pipe-type body 100 having such a structure as a medium.

Specifically, as shown in the figure, the body 100 serves as an inlet for opening one end in the longitudinal direction and connected to the inlet pipe 10, and the other end is closed by a blank flange 120 which can be opened and closed by a user. do.

At least one outlet 110 is formed in the width direction of the body 100 and the body 100 is connected to the outlet pipe 20 through an outlet 110 formed at one side.

A connecting flange 121 for connecting the inlet pipe 10 and a connecting flange 122 for connecting the outlet pipe 20 may be provided at the ends of the pipe type body 100, The body 100 and the inlet pipe 10 / outlet pipe 20 may be connected in the form of flange joints by the connecting flanges 121 and 122. [

The filter 200 is installed along the longitudinal direction inside the body 100 and flows into the pipe type body 100 through the inlet pipe 10 and then filters foreign matter in the seawater flowing through the outlet pipe 20 .

The seawater discharged through the outlet pipe 20 after being filtered through the seawater strainer can be used as a ballast water to maintain the balance of the cooling water or the ship for cooling the engine and to supply various facilities requiring the seawater .

The seawater strainer having such a structure does not need a separate installation space unlike the conventional drum type and can use the pipe type body 100 as it is without consuming additional space, Can be greatly reduced and can be installed in a narrow space.

On the other hand, if the seawater strainer is used for a long time, foreign substances may be stagnated outside the filter 200, which may cause performance deterioration or damage of the seawater pump. Therefore, maintenance and repair such as cleaning and replacement of the filter 200 are necessary.

It is effective that the filter 200 of the seawater strainer is formed so as to be detachable from the pipe-type body 100 so as to be easy to maintain and to be formed in a prefabricated manner.

The filter 200 is detachably attached to the body 100 and is separated into a plurality of unit filters 201 and 202 and 203 that can be engaged and disengaged from each other, 202, and 203 are fastened to each other by fastening means such as bolts, the filter 200 can be easily released and fastened, thereby making maintenance work much easier.

Further, the body 100 may also be formed by fastening a plurality of body modules (for example, 101 and 102) that can be fastened and unfastened to each other, thereby facilitating maintenance.

3 is a diagram illustrating a detailed configuration of the filter shown in FIG.

The above-described filter 200 may include a first filter unit 210 and a second filter unit 220.

3, the first filter unit 210 is disposed at one end of the body 100 connected to the inlet pipe 10, and the second filter unit 220 is disposed in the inner space of the body 100 along the longitudinal direction. .

The first filter unit 210 in the body 100 has a plurality of filter plates opposed to each other so as to have a cross section of "A" or "∧" shape. The first filter unit 210 includes an outlet pipe 20 To filter out foreign matter in the seawater flowing out through the exhaust pipe.

The second filter unit 220 at one end of the body 100 may be installed to filter foreign substances in seawater flowing into the center portion of the body 100 from the inlet pipe 10.

In this case, the seawater flowing into the peripheral portion of the body 100 through the inlet pipe 10 flows into the body 100 composed of a pipe type, Passes through the filter unit 210, is naturally filtered, and then exits to the outlet pipe 20.

The foreign matter in the seawater flowing into the center of the body 100 from the inlet pipe 10 is also filtered by the second filter unit 220 installed at the end of the body 100 connected to the inlet pipe 10.

According to this structure, since the seawater flowing into the body 100 from the inlet pipe 10 and escaping to the outlet pipe 20 passes through a series of paths and is subjected to a filtering process naturally according to the flow of seawater, But can enhance its own filtering capabilities.

The first filter unit 210 at one end of the body 100 and the second filter unit 220 at the inner side of the body 100 may be connected to the pipe type body 100 through the inlet pipe 10, Filtering can be done in all inflow directions without blind spots.

Since the first filter unit 210 and the second filter unit 220 are for filtering foreign substances in seawater, the first filter unit 210 and the second filter unit 220 can be manufactured using stainless steel or the like having high corrosion resistance. For example, A perforated plate having a plurality of through-holes formed therein, and a plurality of nets.

The configuration of the marine strainer for marine use according to the present invention is not limited to the above-described embodiment, but can be variously modified within the scope of the technical idea of the present invention.
