[0002] The filter is an indispensable device on the medium conveying pipeline, usually installed at the inlet end of the pressure reducing valve, pressure relief valve, water level valve, Fanggong filter and other equipment. The ship will be equipped with a seawater filter to provide water to the crew.

[0003] After searching, a seawater filter with an existing announcement number of CN215781915U is found, which includes a filter cartridge, a detachable upper cover on the upper end of the filter cartridge, and the filter cartridge is divided into a water inlet chamber and a water outlet chamber by a partition. The filter cartridge is located on one side of the water inlet chamber and connected to the water inlet pipe, and is located on one side of the water outlet chamber and connected to the water outlet pipe. A filter basket is arranged in the filter cartridge, the filter basket inlet is fixed in the water inlet chamber, and the filter basket extends through the partition to the water outlet chamber. The seawater filter has good corrosion resistance, can increase the filtering area, improve the filtering efficiency, and can meet different pipe layout requirements.

[0004] For seawater filters used in ships, after impurities accumulate in the filter element inside, it needs to be disassembled for inspection or replacement, which is inconvenient to operate and not conducive to automatic flushing and cleaning of the filter element. Therefore, we propose an anti-fouling self-cleaning seawater filter for ships to solve the above problems. Utility Model Content
