Description

Technical Field

[0001] The utility model relates to a discharge device for a liquid collecting tray of a liquid cargo ship. Background Art

[0002] In the currently designed and used liquid cargo ships, the liquid cargo filling station work area is designed on one or both sides of the ship's side. This work area is the loading and unloading station for loading and unloading liquid cargo, such as crude oil, chemicals, etc. This loading and unloading station includes one or more loading and unloading ports, through which it can be connected to the pipeline system on the dock.

[0003] During the process of loading and unloading liquid cargo, liquid will drip. In order to collect liquid, prevent leakage, protect the environment and ensure safe operation, a liquid collecting tray is usually designed to collect the liquid cargo dripping from the loading and unloading port. The discharge device is an important part of the liquid collecting tray, which can ensure that the liquid is effectively discharged without being retained in the liquid collecting tray. The discharge device is mainly composed of a discharge pipe connected to the liquid collecting tray.

[0004] Generally speaking, the liquid cargo collected in the liquid collection tray will be discharged directly to the side, but the design specifications of liquid cargo ships do not allow such devices to exceed the side, so the discharge pipe is usually designed in the following two ways:

[0005] 1. The discharge port of the discharge pipe is placed on the side of the ship, and the liquid is discharged from the discharge port. The disadvantage of this design is that since the discharge port is very close to the side of the ship, the discharged liquid will flow down along the hull of the side of the ship, and the discharged liquid will corrode the paint on the surface of the hull, losing the function of protecting the hull, and destroying the beauty of the hull and the logo painted with paint;

[0006] 2. Place the discharge port of the discharge pipe on the inside of the side of the ship, and close the end flange of the discharge port; when the liquid in the liquid collection tray needs to be discharged, first open the end flange of the closed discharge port, and then connect an external discharge pipe that is long enough to extend to the outside of the side of the ship to discharge the liquid to the outside of the ship; such a design requires the installation and removal of an external discharge pipe, and there may also be liquid leakage during the installation and removal of the external discharge pipe, and the removed external discharge pipe needs a place to be stored. Therefore, the disadvantages of this type of design are that it is troublesome to install and disassemble, and there is a safety risk of liquid leakage at the end flange of the discharge port.
