Description

[Detailed description of the invention] "Field of industrial application" This invention relates to the prevention of sticking of bulk cargo on the inner surface of the cargo hold of a ship.

``Prior art'' Conventionally, bulk cargo in the form of particulates from a ship's hold was directly dumped into the hold, which caused it to stick to the inner surface of the hold due to condensation water, making removal work difficult and labor-intensive. It had the disadvantage that it was difficult to use for the next shipment unless it was repainted, which required a huge amount of money.

``Problems that the invention attempts to solve'' This invention aims to eliminate the above-mentioned drawbacks.
By covering the inner peripheral surface and the corners of the floorboards of the warehouse with a rubber curtain, it is possible to prevent the inner peripheral surface and the corners of the floorboards from sticking, thereby significantly improving the maintenance and management of the warehouse.

``Means for Solving Problems'' This proposal is for a ship that has a rectangular box-shaped cargo hold inside the ship and a hatch cover that can be opened and closed on the upper deck of the hold. The hold is characterized in that a curtain rail is laid on the circumference, and the inner circumferential surface and the corner of the floor board of the hold can be covered in an openable and closable manner with a rubber curtain suspended from the rail through wheels. Ru.

``Operation'' The curtain 5 stored in the corner of the warehouse 2 is moved manually or by power, and the curtain 5 is stretched around the entire circumference.
When the space covered with bulk cargo is filled with bulk cargo, it presses against the inner wall through the curtain 5, so that regardless of the properties of the cargo, no solid matter is generated on the inner wall or the corner of the floor, so removal work can be carried out as usual. There is no need for
After carrying out the cargo, the curtains 5 are bundled along the rails 7 at the corners of the warehouse either manually or by power.

``Example'' As shown in FIGS. 2, 3, and 4, the curtain 5 is suspended by a curtain fitting 8 with wheels 9 on a curtain rail 7 installed in a warehouse 2, either manually or by power. The inner circumferential surface 6 and floor corner 6' of the hold 2 are coated over the entire circumference at the center of the gunwale, and the cargo (cement) is poured into the space 2' from the hatch opening 3'. , powders such as grains, salt, etc.) are introduced and the cargo is gradually filled, and as shown in FIG. 5 and FIG. Since the bulk material enters through the container 2 and comes into pressure contact with the container 2, the inner circumferential surface and corner portions of the store 2 are kept free from contamination and are not solidified by condensed water. After the cargo is discharged, it is cleaned, and the curtain 5 is moved and concentrated along the rail 7 at the inner corner of the warehouse 2 manually or by power, and is used repeatedly. In the figure, 3' indicates the hatch opening, 4 indicates the cargo handling device, and 8
is the engine room, 10 is the deck, 11 is the reinforcing rib,
12 is a side outer panel, and 13 is a floor board.

``Effects'' Since this project is constructed as described above, there is no need to peel off and paint the stuck objects on the inner surface of the warehouse 2, unlike the conventional method.
There are benefits in that maintenance costs within the warehouse can be significantly reduced, there is no risk of staining the inner walls of the warehouse 2, durability and safety are increased, and the cleaning effect within the warehouse can be significantly improved.
