Problems solved by technology

However, the above methods have their own advantages and disadvantages, and their use environments and methods are different, which will cause more or less inconvenience in the process of ballast water treatment
In addition, the existence of ballast water will increase the weight of the ship itself, increase the fuel consumption of the ship, increase the inertia of the ship, and reduce the flexibility of the ship

Embodiment Construction

[0017] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as Figure 1 to Figure 3 As shown, a through-type ballast water tank described in the present invention includes a ballast water tank 1 mounted on the hull. The ballast water tank 1 is provided with several independent compartments 5, and one end of the independent compartment 5 is provided with a water inlet 2. The other end is provided with a water outlet 3, and the water inlet 2 and the water outlet 3 are connected through. An opening is provided on the outer plate below the waterline of the bow of the hull and is connected to the forepeak tank. The peak tanks are connected, and several air ballast systems 4 are arranged on the top of the independent cabin 5, and a movable pressure plate 7 is arranged inside the independent cabin 5, and the movable pressure plate 7 is controlled to move by a mechanical lifting device. ...

Abstract

The invention relates to the technical field of drainage of ballast water in foreign places, in particular to a through type ballast water tank. The through type ballast water tank comprises a ballast water tank body. The ballast water tank body is provided with a plurality of independent cabins. A water inlet is formed in one end of the independent cabins, and a water outlet is formed in the other end of the independent cabins. A plurality of air ballast systems are arranged at the tops of the independent cabins. Movable pressing plates are arranged in the independent cabins, and the movable pressing plates are controlled through a mechanical lifting device to move. By the adoption of the structural setting, real-time communication can be achieved through the water inlet and the water outlet in the sailing process of a ship; through the corresponding arrangement of the air ballast systems and the movable pressing plates, ballast water is drained within the smallest safe range, the situation that microorganisms in seawater or seaweed is brought into foreign fields is avoided, the influence of foreign microorganisms is eliminated fundamentally, and the problem that foreign microorganism invasion caused by drainage of ballast water in foreign places is solved to a great extent; and meanwhile, the ballast water weight in the ship weight is reduced, the load of the ship is reduced, and the sailing efficiency of the ship is improved.

Description

technical field [0001] The invention relates to the technical field of ballast water discharge in different places, in particular to a through-type ballast water tank. Background technique [0002] With the advantages of large carrying capacity and low operating costs, modern ships have always occupied a pivotal position in the global economic field. Today's maritime transport ships in the world are developing in the direction of large-scale, specialization and automation, which inevitably brings a series of problems. Among them, the alien biological invasion caused by the off-site discharge of ballast water from international sailing ships has become more and more popular. attention. If the situation of alien biological invasion is to be alleviated, some measures must be taken artificially. [0003] The methods currently being studied to treat ballast water mainly include: physical treatment methods, such as filtration, improvement of ship design, heating, ultrasonic wave...
