Claims (17)
1. A slurry carrying vessel characterized in that the hold wall is provided with an overflow drain port located suitably above the predetermined loading level of slurry cargo and an on-off valve-equipped free water drain port located below said overflow drain port but slightly above said predetermined loading level and that the hold bottom is provided with a number of filterequipped drain ports.
2. A slurry carrying vessel as set forth in claim 1, wherein said overflow drain port and free water drain port communicate with a vertical drain passageway, and said filter-equipped drain ports are provided in the wall of a drain tunnel horizontally extending along the hold bottom, there being provided a water reservoir space communicating with said drain passageway and drain tunnel, said water reservoir space having a drain pipe extending therefrom.
3. A slurry carrying vessel as set forth in claim 1, wherein said overflow drain port and free water drain port communicate with a vertical drain passageway, and said filter-equipped drain ports are provided in the wall of a drain tunnel horizontally extending along the hold bottom, there being provided separate water reservoir spaces communicating with said drain passageway and said drain tunnel, respectively, each of said water reservoir spaces having a drain pipe extending therefrom.
4. A slurry carrying vessel as set forth in claim 1, wherein an on-off valve-equipped emergency drain port is located at a suitable level between the hold bottom and said free water drain port.
5. A slurry carrying vessel as set forth in claim 1, wherein each of a plurality of holds arranged longitudinary of the ship is provided with said overflow drain port and free water drain port and is provided at the hold bottom with said filter-equipped drain ports, characterized in that the last loading hold has a smaller volum and a greater filter-equipped drain port area per unit volum than the other holds.
6. A slurry carrying vessel as set forth in claim 1, wherein inside a corner between the hold wall and the hold bottom there is a drain tunnel defined by an inclined roof-shaped plate and a longitudinal side plate and extending along said hold wall, and said number of filter-equipped drain ports are provided in said longitudinal side plate.
7. A slurry carrying vessel as set forth in claim 1, wherein there is a drain tunnel extending along the hold wall and defined by said hold wall and an obliquely downwardly projecting curved plate of substantially semi-circular cross-section which interconnects the hold wall and the hold bottom, and said number of filter-equipped drain ports are provided in a partition wall between said drain port and the hold.
8. A slurry carrying vessel as set forth in claim 1, wherein below a position on the hold bottom adjacent to the hold wall there is a drain tunnel defined by a tunnel forming plate extending along said hold wall, and said number of filter-equipped drain ports are provided in a partition wall between said drain tunnel and the hold.
9. A slurry carrying vessel as set forth in claim 1, wherein outside a position on the hold wall adjacent to the hold bottom there is a drain tunnel defined by a tunnel forming plate extending along said hold wall, and said number of filter-equipped drain ports are provided in a partition wall between said drain tunnel and the hold.
10. A slurry carrying vessel as set forth in claim 1, wherein said filter comprises an inner perforated plate facing toward the hold, an outer perforated plate substantially parallelly placed outside said inner perforated plate, and a filter screen applied to said outer perforated plate, there being a space outside said inner perforated plate, the apertures in said inner perforated plate being positIoned in staggered relation to the apertures in said outer perforated plate.
11. A slurry carrying vessel as set forth in claim 1, wherein said filter comprises an annular space one end of which opens to the hold side, a central space which is inside said annular space and one end of which opens to the drain passageway side, a number of small apertures provided in a cylindrical wall between said annular space and central space, and a filter screen covering said small apertures.
12. A slurry carrying vessel as set forth in claim 1, wherein said filter comprises an annular space one end of which opens to the hold side, a central space which is inside said annular space and one end of which opens to the drain passageway side, small apertures provided in a peripheral wall on the outside of said annular space and in a cylindrical wall between said annular space and central space, a filter screen covering said small apertures.
13. A slurry carrying vessel as set forth in claim 1, wherein said filter comprises a metal screen and a fiber screen applied to said metal screen.
14. A slurry carrying vessel as set forth in claim 1, wherein said filter is obliquely outwardly downwardly inclined from the upper edge of an opening provided in contact with the hold bottom in a longitudinal side plate forming hold wall, so that a space of substantially triangular cross-section is defined outside said opening, the angle of inclination of said filter being smaller than the angle of repose of the cargo.
15. A slurry carrying vessel as set forth in claim 1, wherein there is an overflow drain port communicating directly with the outside of the ship through a drain pipe extending through a wing tank located outside the hold wall, said wing tank having defined therein a partitioned working chamber surrounding said drain pipe, said working chamber containing an on-off valve placed in said drain pipe.
16. A slurry carrying vessel as set forth in claim 1, wherein said overflow port has a settling tank communicating therewith at the upper portion, and the drain water in the settling tank overflows from a position not lower than the overflow drain port communication position of said settling tank and is guided to the drain passageway.
17. A slurry carrying vessel as set forth in claim 1, wherein a casing covering said overflow drain port is located on the hold side and provided with a drain inlet equipped with lower boards for causing the cargo mixed in the drain water to settle and separate within said casing, it being so arranged that the cargo which collects on the bottom of said casing can be withdrawn.
