Embodiment Construction

[0065] The bulk carrier and bulk barge of the present invention will be described below with reference to the accompanying drawings. A bulk carrier with propulsion is described here, but the invention is equally applicable to bulk barges without propulsion. In addition, the drawings are only for illustration, and are not necessarily drawn in accordance with the actual ship type or size ratio of the cargo hold. and Figure 9 It is also a diagram used to illustrate loading and unloading methods, and its hull structure is similar to that of Figure 1 to Figure 8 Compared with the hull structure of the ship, the shape of the cargo hold and the discharge port are different.

[0066] Such as Figure 1 ~ Figure 3 As shown, the bulk carrier 1 according to the first embodiment of the present invention includes a cargo hold 10 for loading bulk dry cargo. In this first embodiment, the cargo hold 10 is integrally formed with the hull. That is, the side walls 11 and the like of the ca...

Abstract

Provided are a bulk carrier and a bulk cargo barge, capable of effectively transporting even powders and grains, such as polymer pellets which should be prevented from damage or contamination. In a bulk carrier (1, 1A) on which an unpackaged dry bulk cargo (B) is loaded, in order to reduce the amount of unpackaged dry bulk cargo (B) residue upon unloading and to not cause a shadow area thereby enabling washing out the cargo residue by water-washing and preventing contamination when the cargo is unloaded and another cargo is loaded, a wall of a cargo hold (10, 10A) in which the unpackaged dry bulk cargo (B) is loaded is smoothed without providing rib members projecting inward of the cargo hold (10, 10A), a discharge port (15, 15A) having an inclined portion (12, 12A) is provided in a lower part of the cargo hold (10, 10A), and a gas pipeline (22) connected to the discharge port (15, 15A); is provided to unload the unpackaged dry bulk cargo (B) which is discharged from the discharge port (15, 15A) through a valve (21a), with the help of a flow of a gas (A).

Description

technical field [0001] The present invention relates to a bulk ship and a bulk barge capable of transporting powdery particles such as polymer particles in bags in order to avoid damage and pollution in the conventional technology in bulk. Background technique [0002] In the past, when the polymer pellets were to be transported by ship at sea, container transportation was used, that is, the polymer pellets were bagged and the container containing the bags was transported by a container ship. [0003] Such polymer particles are made of low-density polyethylene, high-density polyethylene, and transparent crystalline (95%) polypropylene, which is called a polymer, into a size of about φ3mm×L3mm to φ6mm×L6mm. grainy. The physical properties of such polymer particles are: the specific gravity is about 0.9 to 1.0, the volume specific gravity is about 0.5, which is relatively light, and the angle of repose is about 30 degrees. Low-density polyethylene has a specific gravity of a...
