Abstract
Description
Technical Field
[0001] The utility model belongs to the field of seawater filters, in particular to a self-cleaning seawater filter for ships. Background Art
[0002] During the voyage of a ship, the computing equipment in the ship needs to be cooled by seawater. Seawater is pumped from the sea by a water pump to cool the equipment. If seawater is directly pumped, the impurities in the seawater will pollute the cooling mechanism of the ship. During the voyage of a ship, fish schools may also be encountered. If seawater is directly pumped, the fish schools may enter the cooling mechanism and affect the operation of the equipment. Before the seawater is pumped, it needs to be filtered through a seawater filter. Only the filtered seawater can be used in the cooling process of the equipment.
[0003] When the seawater filter is filtering, the filtered marine garbage, weeds and other impurities will remain in the filter cartridge of the filter. If there are fish schools, the filter cartridge will be seriously blocked. At this time, the pressure of the water pump is reduced, the pumping speed is reduced, and the seawater circulation and water replacement speed in the ship's cooling mechanism is reduced, which also reduces the cooling efficiency of the ship's computing equipment. Usually, a single seawater filter is opened, the filter cartridge of the seawater filter is taken out, and after cleaning, it is installed and continued to be used. This method requires the seawater filter to be disassembled and assembled back and forth. During the disassembly and cleaning process, the seawater filter cannot be used normally, delaying the normal operation of the ship's mechanical equipment;
[0004] In summary, the utility model provides a self-cleaning seawater filter for ships to solve the above problems. Utility Model Content
