Description

[Detailed Description of the Invention] The present invention relates to a coal ship having a special structure for the coal storage provided in the front part of the engine room (machine room).

Conventional coal-fired ships, for example, have a coal storage as shown in Figure 25, Nippon Naval Architects Complete Edition, Showa Shipbuilding History (Volume 1) (1972-10-30), Hara Shobo, p.297. Since it was simply placed under the upper deck at the front or side of the steam canister room, it was not rational in terms of utilizing the ship's void space or storing and discharging coal.

The purpose of this invention is to solve such problems, and the void space that constitutes the transverse bulkhead of a ship between the sternmost hold and the engine room is used as a coal storage. By providing a coal ship with a configuration in which the coal drop port is located in the engine room, the upper end is extended above the upper deck and is at the same height as the batch coaming height, and the coal input batch is loaded at this projecting part, Its purpose is distantly related, and it allows a large-capacity coal store to be installed between the sternmost hold and the engine room, making effective use of the void space.

One embodiment will be described below based on FIGS. 1 to 3.

Reference numeral 1 denotes a ship, which has a plurality of holds divided by a ship transverse bulkhead 2 in the bow and stern direction, that is, in the embodiment, the sternmost ship 3A.
It has a hold 3B adjacent to this, and an engine room 4.

5A, 5B are batch, 6A, 6B are batch combing,
? A.

7B shows the batch cover.

A coal storage 8 is formed between the sternmost ship 3A and the engine room 4, and is arranged using a void space that constitutes the ship transverse bulkhead 2.

In a cross section, the lower part of this coal storage 8 has a plurality of hoppers 11A formed by a plurality of (three in the embodiment) center hopper members 9A, 9B, 9C and left and right side hopper members 10A, IOB.

Coal outlets 12A, 12B, 12C, and 12D are located in the engine room 4, and coal ports 12A, 12B, 12C, and 12D are located at the lower ends of these hoppers 11A, 11B, and IIC, and 11D.

In the engine room 4, each coal drop port 12A, 12B,
A pair of left and right belt conveyors 1 facing 12C and 12D
3A, 13B and this belt conveyor 13A, 13B
One packet conveyor 15 is arranged at the centerline of the ship to receive the coal sent through the chute 14.
A dispensing tank 17 facing the discharge port 16 of the packet conveyor 15, a conveyor 19 for conveying coal from the dispensing tank 17 to the boiler 18, and a turbine 20 are provided.

The upper end of the coal storage 8 extends above the upper deck 21 and is at the same height as the batch combings 6A, 6B.
3 is formed.

24 indicates a batch cover.

The loading of coal into the coal storage 8 is carried out by the coal loading step 2.
3, but at this time coal input batch 2
Since position 3 is at the same height as the ship's batch coaming 6A, it is easier to operate the grab when loading coal, and more coal can be stored than in a case where the coal storage is located below the upper deck. Can be installed.

Therefore, the cruising distance can be increased accordingly.

The coal in the coal storage 8 is passed to the packet conveyor 15 via the belt conveyors 13A, 13B and the chute 14,
After being conveyed upward by the packet conveyor 15, the packet is passed from the discharge port 16 to the dispensing tank 17.

The coal dispensed from this dispensing tank 17 is transferred to a conveyor 19.
It is conveyed to the boiler 18 via.

Incidentally, coal having a large particle size is crushed by a crusher before being carried into the boiler 18.

In the above embodiment, the coal storage 8 has a hopper-shaped lower part, but it may have a flat shape as shown in FIG. 4.

In this case, a large number of coal drop ports 12 are formed on the bottom plate 25, and the belt conveyor 13 facing these has chute 14A of packet conveyors 15A and 15B distributed to the left and right,
It is possible to supply coal to 14B.

As described above, according to the present invention, a coal storage for securing coal for fuel is formed in the void space that constitutes the ship's transverse bulkhead between the sternmost hold and the engine room, and the coal storage is Since the upper end of the storage is extended above the upper deck, sufficient coal storage space can be secured by making effective use of the void space without increasing the ship's length or installing a separate coal storage, making it suitable for voyages. Necessary coal can be stored and stored.

Further, loading coal into the coal storage can be carried out by an easy grab operation from a coal charging batch formed on an overhang at the same height as the batch combing height.
