Description

[Detailed description of the invention] The present invention relates to a slurry carrier.

For example, when coal or the like is transported by sea using a slurry carrier, it is necessary to dewater the slurry in order to improve the efficiency of its loading and unloading and to reduce transportation costs.

When coal slurry is loaded into a ship's hold, the coal particles are almost uniformly dispersed in Todoroki Hatsu, but as time passes, large particles settle and accumulate in the lower layer depending on the difference in specific gravity, and the coal particles settle in the upper layer. The particles of small size float to the surface.

A commonly used slurry dewatering method is to install a drain with a filter in the bottom of the hold and drain water downward through this drain. However, when this method is applied to the coal slurry drainage, as the drainage progresses, The small-diameter coal particles floating on the upper layer cover the upper surface of the lower layer made of large-diameter coal particles, blocking the internal gaps, that is, the water passageways.

If this happens, drainage efficiency may decrease, or in extreme cases, drainage may become impossible, making it difficult to drain water effectively.

The same thing can be said when draining slurry other than coal slurry.

The present invention provides a slurry carrier that solves these problems.

A first embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Reference numeral 1 denotes a drain port with a filter 3 formed at the lower part of the transverse bulkhead in the hold 2; 4 is a will that collects the waste water that has passed through the drain port 1; Connect the parts.

Reference numeral 6 denotes a plurality of drain ports formed at appropriate locations on the bottom plate 2a, and a water suction portion of the water suction pump 5 is connected to a wheel 7 formed under the drain port 6.

Reference numeral 8 denotes a perforated plate disposed at the drain port 6.

Reference numerals 9 and 10 denote endless band-shaped fibrous water guide bodies disposed in the central vertical part 11a and the lower inclined part 11b of the transverse bulkhead 11, respectively, and each pair of fibrous water conducting bodies fixed to the vertical part 11a and the inclined part 11b are A hook is passed between arms 12.

Further, the vertically opposing water guide bodies 9 and 10 are in contact with or close to each other, and the upper end of the upper water guide body 9 is connected to the hold 2.
This layer is positioned above the layer A of powder and granular material such as coal that has been introduced into the tank and settled.

The reason why the double-groove water bodies 9 and 10 are endless is to prevent them from rotating and breaking when pressed by the powder layer A.

Reference numeral 13 indicates a fibrous longitudinal water body laid along the vertical direction on the bottom plate 2a, and 14 indicates a vertical water guide body 13 between the bottom plate 2a and the longitudinal partition wall 15.
is a fibrous water conductive body laid along a direction perpendicular to the water conductive bodies 13 and 140, and the drain port 6 is located below the intersection of both vertical and horizontal water conductive bodies 13 and 140.

Further, both ends of the horizontal water guide body 14 are placed at substantially the same height as the upper end of the upper water guide body 9.

The water conductors 9, 10, 13, and 14 may be made of the same material as the fiber filter, or may be sponges, as long as they do not allow powder to enter inside and cause clogging, and only allow liquid to pass through.

In the above configuration, for example, when the pump 5 is operated to drain the coal slurry after loading it in the hold 2, even if the passageway in the powder layer A is clogged, the upper water conductor 9 and the side water guide Since the upper end of the body 14 protrudes above the powder layer A, the water accumulated on the powder layer A passes through the upper water conductor 9 from the upper end of the upper water conductor 9, and further The water is guided through the lower water guide body 10 to the drain port 1, and from the upper end of the horizontal water guide body 14 through the horizontal water guide body 14 to the drain port 6, and is drained by the pump 5. be.

Further, the water that has passed through the powder body layer A and its outer peripheral surface and reached the vertical and horizontal bulkheads 15, 11 and the bottom plate 2a is transferred to each water conductor 9,
10, 13° 14 and is drained from drain ports 1, 6.

In the above embodiment, two types of water conductors 9, 10 and 13.14 are used.
However, instead of the horizontal water conductor 14 on the vertical partition wall 14, endless strip-shaped water conductors 9 and 10 may be provided, or on the contrary, an endless strip-shaped water guide body on the horizontal partition wall 11 may be used. In place of 9 and 10, a lateral water guiding body 14 may be provided.

Moreover, instead of the two water conductors 9 and 10 described above, one endless strip-shaped water conductor 16 may be used as shown in FIG.

Reference numerals 17 indicate the central vertical portion 11a and the lower inclined portion 11 of the transverse bulkhead 11;
This is an arm for holding down the water guide body 16 disposed on the bending line with b (the 20th embodiment).

Furthermore, as shown in FIG.
, 10 may be replaced with a single fixed water conductor 18.

19 is a U-shaped water conductor support frame fixed to the horizontal bulkhead 11; 20 is a presser plate disposed above the outer periphery of the water conductor 18 within the support frame 19; and 21 is formed in large numbers on the support frame 19. A bolt screwed into a screw hole provided in the presser plate 20.
is pressed against the water conductor 18 (third embodiment)
.

As described above, according to the slurry carrier of the present invention, the opening in the hold extends from a proper position above the granular material layer charged and settled in the hold on the υ side of the hold to the drainage outlet at the bottom of the opening in the hold. A fibrous water conductor that only allows liquid to pass through is installed along the vessel, so when draining water after putting coal slurry into a ship's hold, the gaps in the settled coal powder layer, that is, the water passageway, will not be clogged. Even if the water is drained, the water is guided to the drain port through the water guide body and drained, and the drain time is completed in a significantly shorter time than in the past.
