ができる運搬船に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier capable of transporting a solid-state cargo and a liquid-state cargo, and more particularly to a bulk carrier for transporting ore and the like, in which a sulfuric acid is supplied to a return route. Carriers capable of transporting such chemical substances to ore producing countries.

Description of the Related Art Heretofore, transportation by a carrier has been carried out by a dedicated ship depending on the form and characteristics of the cargo for the purpose of carrying a large amount of cargo in one voyage. Separate vessels were used, such as tankers for crude oil, LPG vessels for liquefied natural gas, and bulk carriers for ore.

上っている。[0003] For ores used as raw materials for both iron and non-ferrous metals, domestic mines are closed one after another due to resource depletion and rising mining costs, and most of them depend on overseas.
For example, in the free world, copper ingot production is the third largest in the world after the United States and Chile, but the ore's self-sufficiency rate is 1%.
Weak (1992), Canada, United States, Chile,
Imported from Philippines, Indonesia, etc. The total amount of copper ore such as porphyry ore and chalcopyrite is 350

前後に傾かないように設計されている。[0004] In the bulk carrier for transporting ore, the hold space is divided into a plurality of spaces at right angles to the traveling direction of the ship to form a hold. The plurality of holds are arranged substantially symmetrically with respect to the center of gravity line of the ship in the front-rear direction, and are designed so that the ship does not tilt forward and backward due to loading of the cargo.

物を入れることはできない。In the case of the bulk carrier described above and the carrier ship which transports chemical substances such as sulfuric acid,
The outbound route was full of initial shipments, but the inbound route returned empty. This is because the hold of the ship is constructed so as to be compatible only with the cargo to be transported on the outbound route, and other cargo cannot be loaded into the hold. In particular, a solid cargo hold constructed to accommodate a solid-state shipment cannot contain a liquid-state shipment, and is constructed to accommodate a liquid-state shipment. Liquid cargo holds may not contain solid-state cargo.

おいても鉱石と同様に復路が空荷となる欠点があった。[0007] Shipping by sea usually takes several weeks, so operating with empty cargo is a great economic loss and fuel costs are not ridiculous. In particular, since the transportation of the copper ore described above is a round trip on a long sea route, the loss is enormous. In addition, these developing countries import chemicals such as sulfuric acid, which is a raw material for pesticides, because they do not have sufficient facilities for producing chemicals in the country. Sulfuric acid is also exported from Japan because it is produced as a by-product during the copper smelting process. However, as described above, sulfuric acid transport has the disadvantage that the return path is empty, just like the ore.

る。As shown in FIG. 1, the carrier 1 comprises:
This is a ship with a displacement of 40,000 tons, in which a bridge 2 having a rudder room is located behind the hull, and a hold space 3 for storing transported goods is located in front of the bridge 2. The hold space 3 formed inside the hull is divided into 5 at right angles to the direction of travel of the ship, and holds the hold 11, 21, 31, 41, 5 in order from the bow side.
It is set to 1. Of course, the hold space 3 may be divided into any number as long as the plurality of holds are arranged substantially symmetrically with respect to the longitudinal center-of-gravity line Y-Y passing through the center of gravity of the ship, and the number may be an even number. . Each of these holds is formed substantially symmetrically with respect to the center line XX in the traveling direction of the ship. This is to prevent the hull from tilting about the center line XX. The plurality of holds are also arranged substantially symmetrically with respect to the longitudinal centerline YY passing through the center of gravity of the ship. This is to prevent the hull from tilting about the center of gravity line YY, that is, to prevent the bow or stern from sinking with respect to the other. A plurality of solid cargo holds 11,
31 and 51, and a plurality of liquid cargo holds 2
The total accommodation tonnage of 1, 41 can be set substantially equal. Thereby, the transportable tonnage on the outward route and the return route can be made equal, and the transport efficiency of the transport ship 1 can be maximized.

は大きい。The solid cargo holds 11, 31 and 51 for containing solid ore or other such cargoes are odd-numbered from the bow side, and the liquid cargo holds for containing liquid such as sulfuric acid. Reference numerals 21 and 41 are located at even numbers from the bow side. When the solid cargo or the liquid cargo is evenly loaded in the hold in such an arrangement, the cargo is symmetrically distributed with respect to both the center line XX and the center of gravity YY. . As a result, the hull moves up and down with respect to the water surface while maintaining the horizontal state. Even if the hull is tilted back and forth due to pitching, the solid cargo does not move in the solid cargo hold, and the position of the center of gravity of all the solid cargo in the hold does not change like the liquid cargo. Therefore, as compared with a carrier in which odd-numbered liquid cargo holds are arranged and even-numbered solid cargo holds are arranged, the stability with respect to the forward and backward inclination is greater.

Therefore, when attention is paid only to the solid cargo holds, they are arranged symmetrically with respect to both the center line XX and the center of gravity line YY. Similarly, the liquid cargo holds 21, 41 also
They are arranged symmetrically with respect to both the center line XX and the center line YY. Therefore, in both cases where the outbound route transports solid transported material and the return route transports both solid transported material and liquid transported product on the return route, the transported product is transported to the center line of the hull. It can be loaded symmetrically with respect to both XX and the center of gravity line YY.

Conventionally-known cranes 61, 63 and 64 are used for taking in and out of the solid transported goods. While the carrier 1 is navigating, the openings are covered with hatches 12, 32, and 52. This prevents intrusion of rainwater and the like.

Put in and out. The discharge pipes 24, 44 are connected to pumps 28, 48 arranged in the pump chambers 22, 42, whereby the liquid transported material is discharged from the liquid transport cargo holds 21, 41. Injection pipes 22, 42
The discharge pipes 23 and 43 are preferably provided on both the port side and the starboard side, respectively, so that the carrier 1 may berth on either side.

Details of 1, 41 are shown. Hold for liquid cargo 2
1 and 41 have central partition walls 25 and 45 extending along the center line XX in the traveling direction of the ship. As a result, each of the liquid cargo holds 21, 41 is arranged symmetrically with respect to the center line XX of the ship.
1b; 41a, 41b. Each of the liquid cargo holds 21, 41 is divided into two or more in the width direction of the ship, and the liquid cargo is stored in the respective liquid cargo compartments, so that even if the hull tilts in the left-right direction, the balance is remarkable. There is an advantage that it does not break.
