Problems solved by technology

[0002] In the design of traditional ships and ocean engineering platforms, most of the designs are single-function designs for seawater inhalation, and cannot handle seawater suspended matter and sediment, especially in offshore fishing nets, plastic bags and seaweed. There is a lot of marine garbage, which is easily inhaled by the sea tank, causing the filter blockage of the seabed door and the ship's piping system and accelerating the wear of the seawater pump blades, affecting the normal operation of the seawater system. Severe blockage will lead to high seawater outlet temperature. Cause high temperature alarm of ship equipment, shutdown and equipment overheat alarm, thus affecting the normal navigation of the ship, and even causing the ship to crash

Abstract

The invention belongs to the technical field of seawater filters, and discloses a sea chest, a seawater filter and a use method. The sea chest comprises a sea chest body, a ship body outer plate, a sea grid, a connecting flange I, a seawater filtering grid assembly, a sea gate valve, a first compressed air pipe and a second compressed air pipe; the device is small in size, multifunctional and suitable for the technical field of ships and ocean engineering, is used for extracting sufficient seawater for a seawater system, a ballast system and other ship auxiliary systems of a ship or ocean engineering platform, effectively prevents marine litter or dirt from entering the ship system and effectively discharges the marine litter or dirt, and prevents ship system faults.

Description

technical field [0001] The invention relates to the technical field of seawater filters, in particular to a seabed door, a seawater filter and a use method. Background technique [0002] In the design of traditional ships and ocean engineering platforms, most of the designs are single-function designs for seawater inhalation, and cannot handle seawater suspended matter and sediment, especially in offshore fishing nets, plastic bags and seaweed. There is a lot of marine garbage, which is easily inhaled by the sea tank, causing the filter blockage of the seabed door and the ship's piping system and accelerating the wear of the seawater pump blades, affecting the normal operation of the seawater system. Severe blockage will lead to high seawater outlet temperature. Cause high temperature alarm of ship equipment, shutdown and equipment overheat alarm, thereby affecting the normal navigation of the ship, and even causing the ship to crash. [0003] In the design of new ships, th...
