Description

Cargo hold inlet water treatment device and treatment method

Technical Field

The invention relates to the technical field of ships, in particular to a cargo hold inlet water treatment device and a treatment method.

Background

In the transportation industry, ship transportation plays an important role. The cargo hold of a bulk cargo ship is generally used for loading dry bulk cargos such as ores, coal, grains and the like, and has the characteristics of large size, large opening and the like. A hatch cover is disposed in a cargo hold of a bulk carrier, and the hatch cover is generally large in size and can block wind and rain. When a ship sails on the sea, if severe weather occurs, the head of the ship can greatly wave, and sea waves can repeatedly flap the hatch cover of the ship. The sealing performance of the hatch cover is difficult to resist the wave slapping under severe sea conditions, which leads to the water entering the cargo hold. If the inlet water of the cargo hold is accumulated continuously, a large safety risk is generated to the operation of the ship.

Therefore, a cargo hold inlet water treatment device and a treatment method are needed to solve the technical problems.

Detailed Description

The technical scheme of the invention is further explained by combining the attached drawings and the embodiment. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the elements associated with the present invention are shown in the drawings.

In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection or a removable connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In order to prevent the influence of excessive accumulated water in the cargo hold on the cargo and ensure the safe operation of the ship, as shown in fig. 1, the invention provides a cargo hold water inlet treatment device, which comprises a water collecting well 3, a ballast pipe 1, a water collecting pipe 4 and a ballast pump 2; the water collecting well 3 is arranged in the cargo hold and is used for collecting water entering the cargo hold; specifically, the water collecting well 3 is separated from the cargo hold, so that water is prevented from flowing into the cargo hold to pollute the cargo, and the ballast pipe 1 is arranged at the bottom of the cargo hold; the water collecting pipe 4 is arranged in a water collecting well 3 at the bottom of the cargo hold, one end of the water collecting pipe is communicated with the water collecting well 3, the other end of the water collecting pipe is communicated with the ballast pipe 1, and accumulated water is discharged into the ballast pipe 1 through the water collecting pipe 4; the ballast pump 2 is communicated with the ballast pipe 1 and is used for discharging accumulated water in the ballast pipe 1 out of the ship, so that the safe operation of the ship is ensured.

Further, this cargo hold processing apparatus of intaking still includes one-way check valve 5, and one end and the collector pipe 4 intercommunication of one-way check valve 5, the other end and sump pit 3 intercommunication. By providing a single check valve it can be ensured that standing water can only be discharged from the water collection well 3 into the ballast pipe 1, but not from the ballast pipe 1 into the water collection well 3.

Further, the cargo inlet treatment device further comprises a water level detector, wherein the water level detector is arranged in the ballast pipe 1 and is used for detecting the water level height in the ballast pipe 1. Because ponding is more at one side ponding that ballast pipe 1 is close to ballast pump 2, need monitor in real time, specifically, water level detector sets up the one end of being connected at ballast pipe 1 and ballast pump 2. In this embodiment, the water level detectors are provided in plurality, and the provision of a plurality of water level detectors can ensure that the water level in the ballast pipe 1 can still be monitored in real time when one or more water level detectors have a problem.
