Description

Technical Field

[0001] The utility model relates to the technical field of ship engineering, in particular to a buffer device at the end of a breather pipe for a ship oil tank. Background Art

[0002] Breather pipes are provided inside various oil tanks on a ship to balance the air pressure inside the tank and enable smooth suction of the oil. During the navigation of the ship, vibrations and shakes are inevitable, which causes liquid level fluctuations and splashes inside the oil tank. When the fluctuating liquid level exceeds the lowest point of the air pipe, it is inevitable that oil enters the breather pipe, and the next fluctuation will continue to pour in. As time goes by, the concentration of the oil entering the breather pipe increases, which easily causes blockage of the breather pipe. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a buffer device at the end of a breather pipe for a ship oil tank, which keeps the breather pipe smooth and prevents oil from entering the breather pipe and causing blockage.

The breather pipe, the buffer steel pipe, and the sealing plate are arranged on the same central axis; a plurality of steel pipe openings are opened on the circumferential side wall of the buffer steel pipe, and two sealing plate openings are opened on the sealing plate. One of the sealing plate openings is located at the center of the sealing plate, and the other sealing plate opening is arranged at an interval on the side close to the bow of the sealing plate opening located at the center of the sealing plate.

[0006] Further, the plurality of steel pipe openings include two groups of circular openings and one group of semi-circular openings. One group of semi-circular openings is located at the top end of the side wall of the buffer steel pipe, and the two groups of circular openings are arranged at an interval up and down below the semi-circular openings.

[0007] Further, the two groups of circular openings and one group of semi-circular openings are all circularly distributed.

[0008] Further, the diameter of the sealing plate is larger than the diameter of the buffer steel pipe, and the diameter of the buffer steel pipe is larger than the diameter of the breather pipe.

[0009] Further, the distance between adjacent two groups of the two groups of circular openings and one group of semi-circular openings is 115 mm.

[0010] Further, the diameters of the steel pipe openings and the sealing plate openings are both 50 mm.

[0011] Further, the length of the buffer steel pipe is 300 mm.

[0012] The buffer device at the end of the breather pipe of the ship's oil tank of the present utility model can ensure the smoothness of the liquid level below the air pipe as much as possible without affecting the volume of the oil tank, greatly reducing the possibility of blockage of the air pipe of the oil tank; the structure is simple, convenient for disassembly, installation and maintenance; it has a wide range of applications, and breather pipes of various diameters of the oil tank can be used.
