AI Technical Summary

Technical Problem

In the oil tank on a large ship, part of the liquid adheres to the inner wall of the storage tank when the liquid moves, and evaporates with the air as the floating plate moves, producing harmful gases and polluting the environment.

Method used

A floating disk sealing structure is designed, including a storage tank and a floating disk. The floating disk is arranged in the interior of the storage tank. A sealing component is arranged between the floating disk and the storage tank. The sealing component includes an arc-shaped elastic sealing plate, a closed shrapnel and a flexible diaphragm. The upper and lower movements of the floating disk drive the movement of the flexible diaphragm, so that the harmful gas generated between the closed shrapnel and the elastic sealing plate is discharged and collected.

Benefits of technology

It effectively realizes the collection and emission of harmful gases, avoids environmental pollution, and improves the sealing performance between the floating disk and the storage tank. The device is simple in structure and easy to use.
