Description

Technical Field

[0001] This utility model relates to the field of marine ventilation technology, specifically a marine air intake filtration device. Background Technology

[0002] During ship operation, equipment such as engines require a large amount of fresh air for combustion and cooling. However, the marine environment in which ships operate contains a large amount of salt, sand, oil, and other impurities. If these impurities directly enter the ship's engine air intake system or other equipment that requires clean air, they will cause serious damage to the equipment.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219061855U) discloses a ship air intake filtration device. This device solves the problem that cleaning the filter requires disassembly, which causes time delays during the disassembly and assembly process. Furthermore, the inability to clean the filter during filtration results in wasted time and reduced filtration efficiency. The device includes a frame, with symmetrical fixing rods at its bottom and a second frame at its top. One end of the first frame is connected to an air inlet pipe, and the other end to an air outlet pipe. A groove is formed in the middle of the inner bottom of the first frame, with filter frames symmetrically arranged on both sides of the top of the groove. Each filter frame contains a filter screen. This design achieves dual filtration, effectively improving filtration quality. Simultaneously, it avoids removing the filter screen during cleaning, effectively reducing disassembly and assembly time and thus improving the filtration efficiency of the ship's air intake.

[0004] However, although traditional ship air intake filtration devices have a certain filtration capacity, their filtration efficiency is poor. When faced with fine particles and harmful gases in the air, the interception and purification effect of the device is extremely limited, making it difficult to meet the stringent requirements of modern ship equipment for high-quality air intake.

[0005] Therefore, this utility model provides a ship air intake filtration device to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a ship air intake filtration device, such as Figs. 1 to 4As shown, the system includes a housing filter base 1, an internal gas chamber 101 within the housing filter base 1, a connecting side plate 2 fixedly mounted on the inner wall of the housing filter base 1, an air inlet 201 on the upper surface of the connecting side plate 2, a stepped end on one side of the connecting side plate 2, an angled frame 3 fixedly mounted at the connection between the inner wall of the connecting side plate 2 and the housing filter base 1, a filter element medium 301 fixedly mounted on the top of the inner wall of the angled frame 3, the angled frame 3 being placed on the other side of the air inlet 201, and two side frames 4 fixedly mounted on the side of the connecting side plate 2 away from the angled frame 3. A filter cavity 401 is fixedly installed in the middle. The filter cavity 401 is placed on the other side of the air inlet 201. The side plate 2 and the side frame 4 are installed in the housing filter base 1 on the same plane. An air outlet 102 is provided on the side of the housing filter base 1 away from the side frame 4. A surrounding member 5 is movably sleeved on the outer arc surface of the air outlet 102. A sealing receiving recess 501 is provided on one side of the outer arc surface of the surrounding member 5. An extension locking end 502 is provided at the top of the outer arc surface of the surrounding member 5. The inner arc surface of the extension locking end 502 is locked to the top of the air outlet 102. An inner hook end 503 is provided at the tail end of the sealing receiving recess 501.

[0025] A surround 5 is snapped onto the air outlet 102 on one side of the filter base 1. The filter cartridge 6 is fitted inside the inner arc surface cavity of the surround 5, and the inner arc surface of the surround 5 is provided with an inner hook end 503. One end of the inner hook end 503 is snapped onto the filter cartridge 6. A conical kit 7 is fitted onto the tail end of the filter cartridge 6, and the concave sealing part 701 provided in the inner arc surface is tightly fitted into the inner arc surface of the filter cartridge 6, effectively preventing unfiltered air from bypassing into the system. When air flows in, the sealed space formed by the concave sealing part 701 can initially buffer and guide the airflow, allowing the airflow to converge more evenly towards the filter nozzle 702. Its surface is covered with densely distributed micropores. When working in conjunction with the concave sealing part 701, the air, after being guided by the concave sealing part 701, is forced to pass through the filter nozzle 702. At this point, fine particles in the air, such as dust and tiny metal fragments, are blocked on the outer surface of the filter nozzle 702 because their particle size is larger than the micropore size of the filter nozzle 702. For harmful gases, the filter nozzle 702 may use special adsorption materials, such as activated carbon, utilizing its porous structure and adsorption properties to adsorb harmful gas molecules inside the filter nozzle 702, thereby achieving highly efficient filtration of fine particles and harmful gases.

[0026] A filter cartridge 6 is movably fitted onto the inner arc surface of the air outlet 102. The filter cartridge 6 has a conical structure. One side of the inner hook end 503 is movably engaged with the outer arc surface of the filter cartridge 6. The outer arc surface of the filter cartridge 6 has several filter holes 601. A conical kit 7 is movably fitted onto the tail side of the filter cartridge 6. The inner arc surface of the conical kit 7 has a concave sealing part 701. The outer arc surface of the concave sealing part 701 corresponds to one side of the filter cartridge 6. The outer arc surface of the conical kit 7 has a filter nozzle 702. One side of the filter nozzle 702 is placed on one side of the angle frame 3. The filter cartridge 6 and the side frame 4 are in the same plane.

[0027] Simultaneously, gas enters the interior of the housing filter base 1 through the air inlet 201. Since filter media 301 and filter chamber holes 401 are provided on both sides, the gas is quickly diverted after entering. A portion of the gas rushes directly to the filter media 301 on one side. Due to the fine pore structure of the filter media 301, larger dust particles, sand, and other impurities are immediately intercepted, achieving initial filtration. Subsequently, the pre-purified gas flows into the filter chamber holes 401 connected to it. Inside the filter chamber holes 401, the airflow speed slows down, and the chamber may be equipped with an adsorption layer or a special turbulence structure. This not only further captures fine particles but also adsorbs harmful gas molecules, thus deeply purifying the gas.

[0028] Meanwhile, another portion of the gas follows a symmetrical path, passing through the dual filtration of the filter media 301 and the filter cavity 401 on both sides. Most impurities and harmful components are removed, allowing pure gas to converge inside the outer shell filter base 1 and be stably output towards the subsequent air outlet channel, providing clean and high-quality air intake for the ship's equipment and effectively ensuring the efficient and stable operation of the ship's equipment.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
