[0002] Usually, during navigation, ships inhale seawater from sea-going pipelines, which flows through the water inlet pipes of the heat exchangers and the internal heat exchange pipes, thereby reducing the temperature of the circulating water inside the ship and cooling the electromechanical equipment. However, there are a lot of debris in the seawater, such as aquatic plants, sand and gravel, and plastic. If not filtered, the debris will enter the pipeline with the seawater and accumulate at the heat exchanger port and inside, causing a series of problems such as pipeline blockage and corrosion, and low heat exchange efficiency. Therefore, corresponding filters must be installed in the seawater loop of the cooling system;

[0003] After being used for a period of time, traditional seawater filters will become clogged with impurities on the filter cartridge, reducing the filtering effect. The filter cartridge needs to be disassembled and cleaned for reuse. It cannot be used continuously and the filtering efficiency is low. Utility Model Content

[0018] Three symmetrically distributed fixing rods 23 are fixedly provided on the upper surface of the first fixing block 2, and fixing plates 24 are movably provided on the fixing rods 23. A rotating plate 25 is fixedly provided at one end of the three fixing plates 24 away from the fixing rods 23. A first motor 26 is fixedly provided on the upper surface of the filter housing 1, and the output shaft end of the first motor 26 is fixedly provided on the upper surface of the rotating plate 25. The rotating plate 25 can be driven by the first motor 26, thereby driving the first fixing block 2 to rotate. When the second fixing block 21 rotates, the cleaning scraper 22 will follow its movement to clean the surface of the filter cartridge 14.

[0019] A filter screen 27 is fixedly provided at one end of the water inlet pipe 12 away from the filter housing 1 ; the filter screen 27 can isolate large impurities from the outside.

[0020] A plurality of equally spaced sewage scrapers 3 are fixedly disposed on the lower surface of the second fixed block 21 , and a sewage trough 31 is formed through the first positioning block 15 ; impurities scraped off by the cleaning scraper 22 can be pushed into the sewage trough 31 through the sewage scrapers 3 .

[0024] Working principle: When in use, unfiltered seawater enters the water inlet pipe 12 through the water inlet 13, and then enters the filter housing 1 through the first water opening 11. After entering the filter housing 1, the seawater will be filtered by the filter cartridge 14. The filtered seawater will enter the filter cartridge 14 and pass through the second positioning block 16, the second water opening 17, the drain pipe 18, and finally be discharged through the drain port 19.

[0025] While filtering the seawater, impurities in the seawater will adhere to the outer wall of the filter cartridge 14. At this time, the staff starts the first motor 26. Since the output shaft end of the first motor 26 is fixedly arranged on the upper surface of the rotating plate 25, the fixed plate 24 is fixedly arranged on the rotating plate 25, and the fixed plate 24 is movably arranged on the fixed rod 23. The fixed rod 23 is fixedly arranged on the upper surface of the first fixed block 2, the first motor 26 will drive the first fixed block 2 to rotate when it is working. Since the cleaning scraper 22 is fixedly arranged on the lower surface of the first fixed block 2, when the first fixed block 2 is working, the cleaning scraper 22 is fixedly arranged on the lower surface of the first fixed block 2. When the cleaning scraper 22 rotates, it will move with it and clean the outer wall of the filter cartridge 14, scraping the impurities on the outer wall of the filter cartridge 14 and dropping them on the upper surface of the first positioning block 15. Since the cleaning scraper 22 is fixedly arranged on the upper surface of the second fixed block 21, and the sewage scraper 3 is fixedly arranged on the lower surface of the second fixed block 21, when the cleaning scraper 22 moves, the second fixed block 21 will rotate with it.
