Description
Technical Field
[0001] The utility model relates to the technical field of ship fuel filtration, in particular to a ship fuel filtration system with multi-layer filtration components. Background Art
[0002] Ship equipment refers to any movable but non-consumable items used on board except for ship spare parts. It mainly includes rudder equipment, anchor equipment, mooring equipment, towing equipment, lifting equipment, life-saving equipment, closing equipment, piping, outfitting, bilge water system, ballast system, daily water system, fire fighting equipment, ventilation, air conditioning and refrigeration equipment, etc. At present, ship engines are basically internal combustion engines, mainly using gasoline and diesel fuel. As a fuel, there must be certain requirements for the quality and cleanliness of the oil. Due to refining and processing reasons, the finished fuel contains a certain amount of impurities, moisture and colloid. The function of the fuel filter is to filter out these impurities in the fuel;
[0003] After checking the publication number: CN217939378U, a multi-layer filter device for marine machinery fuel oil is disclosed. This technology discloses "a multi-layer filter device for marine machinery fuel oil, including a filter cartridge, and also including a filter mechanism and a sealing gasket for filtering mechanical fuel oil, the filter mechanism is detachably connected to the upper end of the filter cartridge, and the lower end is attached to the inside of the filter cartridge, the sealing gasket is arranged on the lower surface of the filter mechanism, the filter mechanism is composed of a portable cover, a threaded rod, a threaded ring and a filter plate, the threaded rod is detachably connected to the lower surface of the portable cover, the threaded ring is threadedly connected to the surface of the threaded rod, and there are multiple threaded rings, and the filter plate is fixedly connected to the outer wall of the threaded ring" and other technical solutions, which have "when filtering the fuel oil, the filter mechanism and the non-solid impurity filter mechanism are installed separately, reducing the disassembly base of the non-solid impurity filter mechanism, and only the filter mechanism needs to be cleaned, reducing the cleaning difficulty and ensuring the filtering effect" and other technical effects;
[0004] The above scheme achieves the effect of step-by-step filtration through multiple filter plates. However, in actual operation, since the top coarse filter layer will first come into contact with the fuel, the larger impurities in the fuel will directly adhere to the surface of the coarse filter layer when flowing through the filter layer. As time goes by, the accumulation of these impurities will not only cause the filtration efficiency of the coarse filter layer to gradually decrease, but may also cause the filter holes to be blocked, thereby affecting the normal circulation of the fuel.
