Description

[Detailed description of the invention] This invention relates to the ship hold structure, especially the ship hold structure of a slurry cargo carrier, and its purpose is to dewater as quickly as possible only the slurry water of the slurry powder coal etc. loaded in the ship. The aim is to provide a hold structure that will

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

1 is a slurry carrier vessel.

In the lower portions of the left and right side walls 2, 2 of the ship 1, side dehydration trunks 3 are provided in a concave shape with a gentle downward slope toward the rear, and in the lower part of the rear wall 4, a mountain-shaped, i.e. A rear dewatering trunk 5 is provided in a concave shape with a gentle downward slope from the center to the left and right.
A plurality (three in this embodiment) of vertical dewatering trunks 6 are provided in a concave shape in the vertical direction and communicate with each other.

Each of the above dehydration trunks 3. 5. A porous pressure receiving plate 7 and a filtration device 8 are provided in the communication ports 3a, 5a, 6a with the ship 1 in order from the inside of the hold toward the outside.

The above-mentioned filtration device 8 is attached near each of the communication holes 3a, 5a, and 6a, and consists of a porous plate 8a made of vinyl chloride synthetic resin having many through holes, and a filter plate 8a supported on the front surface of the porous plate 8a. It is composed of a mesh filter 8b.

Further, the porous pressure receiving plate 7 is made of a steel plate having many through holes, and is connected to the communication port 3 a of each dehydration trunk 3, 5.6.
, 5a, 6a are inserted and supported by a pair of guides 9 provided on both sides or above and below.

For example, in the vertical dewatering trunk 6, as shown in FIG. In the trunks 3 and 5, as shown in FIG. 4, a pair of guides 9 are provided above and below each communication port 3a*5a to guide and support the pressure receiving plate 7b.

The pressure receiving plates 7b provided on the side and rear dewatering trunks 3 and 5 are, for example, as shown in FIG. The pressure receiving plate 7a provided on the vertical dewatering trunk 6 is removable from above the guide 9.

Note that the pressure receiving plate 7a of the vertical dewatering trunk 6 is composed of a single plate, and the pressure receiving plate 7b of the side and rear dehydrating trunks 3 and 5 has a double plate structure. 7a may have a double plate structure.

Furthermore, the pressure receiving plates 7b of the side and rear dewatering trunks 3, 5 may be of a single plate type, and a plurality of reinforcing ribs may be attached to the back surface thereof in an inclined manner.

Therefore, when slurry-like powdered coal is put into a ship's hold, it will be classified in the large ship's hold due to the particle size difference of the powdered coal, and coal with larger particle sizes will accumulate on the bottom and inside walls of the ship.
Since many dewatering trunks, that is, side, rear, and vertical dewatering trunks are provided in this part, the dewatering performance is improved.

In addition, the side and rear dewatering trunks 3 and 5 are gently tilted so that the powdered coal that accumulates in the area between the filtration device 8 and the pressure receiving plate 7 can be easily removed by the agitation of the slurry water during the next slurry loading. I am making it possible to pay it out.

That is, when the water level of the slurry water rises to around the dehydration trunks 3 and 5, the water surface is shaken by the slurry water that has been introduced, and a portion of the slurry water flows into the dehydration trunks 3 and 5.
5, the pulverized coal also jumps between the filtration device 8 and the pressure receiving plate 7, and the powdered coal accumulated between the filtration device 8 and the pressure receiving plate 7, together with the slurry water, flows into the end of the filtration device 8, for example, the pressure receiving plate 7.
It is swept up to the cutout part of the attachment/detachment guide 9 and discharged into the ship 1.

Note that dehydration of slurry water will be explained here.

Slurry pulverized coal introduced into the ship 1 is transferred to each dewatering trunk 3, 5, and 5 by a pressure receiving plate 7. Therefore, when the drain pump (not shown) is operated, the slurry water first passes through the pressure receiving plate 7, but this slurry water contains some powdered coal.

Then, some of this pulverized coal is effectively removed by the wire mesh 8b of the next filtering device 8, and only the slurry water is drained overboard from each dewatering trunk 3, 5.6.

As described above, according to the ship structure of the present invention, only the slurry water of the slurry cargo can be dehydrated very easily and quickly, and the cargo remaining between the filtration device and the pressure plate, such as powdered coal, can be dehydrated very easily and quickly. can be easily discharged during the next slurry loading.
