[0022] 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.

[0023] Please see Figures 1-7 This utility model discloses a combined layered purification structure device for a ship air conditioning return air vent, including a filter tube 1, a filter layer component inside the filter tube 1, an electrostatic tube 2 installed at the air outlet end of the filter tube 1 by connecting screws, an electrostatic adsorption component on the electrostatic tube 2, an activated carbon adsorption layer 3 fixedly connected at the air outlet end of the electrostatic tube 2, a return air duct 4 installed on the side of the activated carbon adsorption layer 3 away from the electrostatic tube 2 by fastening screws, a negative ion generator 5 installed inside the return air duct 4, and an airflow sensor 6 fixedly connected inside the air outlet end of the return air duct 4.

[0024] Specifically, the filter layer components include a primary filter 7, a medium-efficiency filter 8, and a high-efficiency filter 9. A conical ring 10 is fixedly connected to the surface of each of the primary filter 7, the medium-efficiency filter 8, and the high-efficiency filter 9. A positioning screw 11 is fixedly connected inside the filter tube 1. The conical ring 10 is movably sleeved on the surface of the positioning screw 11, and a nut is threaded onto the positioning screw 11.

[0025] In this implementation scheme, the gas will pass through the primary filter 7, the medium-efficiency filter 8 and the high-efficiency filter 9 in sequence to achieve multi-stage filtration.

[0026] Specifically, the activated carbon adsorption layer 3 includes a carbon-fixing mesh frame 301, an upper cover plate 302, and a lower cover plate 303. The upper cover plate 302 and the lower cover plate 303 are fixedly connected to the upper and lower surfaces of the carbon-fixing mesh frame 301 respectively by connecting screws. One side of the carbon-fixing mesh frame 301 is fixedly connected to the electrostatic tube 2, and the other side is fixedly connected to the return air duct 4.

[0027] The carbon-fixing mesh frame 301 has a column 12 inside, the surface of the column 12 has a diamond-shaped protrusion 13, the surface of the carbon-fixing mesh frame 301 has a positioning protrusion 14, and the column 12 has a positioning groove 15. The positioning protrusion 14 and the positioning groove 15 are movably connected.

[0028] In this embodiment, after adding new activated carbon particles, the column rod 12 is moved up and down to stir the new activated carbon particles with the diamond-shaped protrusions 13 on the column rod 12, thereby reducing the gap.

[0029] Specifically, the electrostatic tube 2 includes a first connecting tube 201 and a second connecting tube 202. The first connecting tube 201 is fixedly connected to the filter tube 1, and the second connecting tube 202 is fixedly connected to the carbon fixation mesh frame 301. The electrostatic adsorption assembly includes a rotating tube 16 and an electrostatic generator 17. The rotating tube 16 is connected to the first connecting tube 201 and the second connecting tube 202 through a connecting bearing. The electrostatic generator 17 is fixedly connected to the rotating tube 16, and the adsorption plate of the electrostatic generator 17 is fixedly connected through the rotating tube 16 and extends into the interior of the rotating tube 16. The surface of the rotating tube 16 is fixedly fitted with teeth 18, and the surface of the first connecting tube 201 is fixedly connected with a drive motor 19. The output shaft of the drive motor 19 is fixedly connected with a gear 20, and the teeth 18 mesh with the gear 20.

[0030] In this embodiment, the drive motor 19 is started, and the rotating tube 16 can be rotated through the gear 20 and the teeth 18, thereby causing the adsorption plate to rotate, which can more effectively perform electrostatic adsorption.

[0031] Specifically, an air guide shroud 21 is fixedly connected inside the return air duct 4, and an airflow sensor 6 is located between the air guide shroud 21 and the return air duct 4.

[0032] In this embodiment, the air guide shroud 21 can guide the gas flow, allowing the gas to come into more effective contact with the negative ion generator 5.

[0033] Specifically, the air inlet of the filter tube 1 is fitted with a disinfection tube 22 by screws, and the inside of the disinfection tube 22 is equipped with an ultraviolet lamp tube 23 and an infrared lamp tube 24.

[0034] In this embodiment, the gas first passes through the disinfection tube 22, where the ultraviolet lamp 23 and infrared lamp 24 disinfect the gas to prevent live bacteria from growing and multiplying on the filter layer component after being filtered by the filter layer component.

[0035] The working principle and usage process of this utility model are as follows: During use, the gas first passes through the disinfection tube 22. The ultraviolet lamp 23 and infrared lamp 24 in the disinfection tube 22 disinfect the gas, preventing live bacteria from growing and multiplying on the filter layer components after being filtered. The gas then sequentially passes through the primary filter 7, the medium-efficiency filter 8, and the high-efficiency filter 9, achieving multi-stage filtration.

[0036] Then it enters the electrostatic tube 2, where the electrostatic generator 17 is energized to generate static electricity, causing impurities to be adsorbed onto the adsorption plates, thus achieving electrostatic adsorption. At the same time, the drive motor 19 starts, and through the gear 20 and teeth 18, the rotating tube 16 can be rotated, thereby causing the adsorption plates to rotate, which can more effectively carry out electrostatic adsorption.

[0037] The gas then enters the activated carbon mesh frame 301, where it undergoes further filtration and adsorption. Finally, it enters the return air duct 4, where the negative ion generator 5 produces a large number of negative ions. These negative ions neutralize the positive ions in the air, purifying it. The air guide hood 21 guides the gas flow, allowing for more effective contact between the gas and the negative ion generator 5.

[0038] Airflow sensor 6 monitors airflow in real time. When the detected airflow is below a set threshold, a blockage is determined. The primary filter 7, secondary filter 8, and high-efficiency filter 9 are disassembled and replaced. Simultaneously, the upper cover 302 and lower cover 303 are removed, causing the activated carbon granules to fall out automatically. The lower cover 303 is then installed, and new activated carbon granules are added. By moving the column rod 12 up and down, the diamond-shaped protrusions 13 on the column rod 12 agitate the new activated carbon granules, reducing the gaps.

[0039] In summary, the combined layered purification structure of this ship's air conditioning return air vent first disinfects the gas through the ultraviolet lamp 23 and infrared lamp 24 in the disinfection tube 22 to prevent bacterial growth on the filter layer components; then it passes through the primary filter 7, medium-efficiency filter 8, and high-efficiency filter 9 in sequence for multi-stage filtration; subsequently, in the electrostatic tube 2, the electrostatic generator 17 generates electrostatic adsorption of impurities, and the drive motor 19 drives the rotating tube 16 to rotate, causing the adsorption plates to rotate and improving the adsorption effect; next, in the activated carbon adsorption layer 3, the activated carbon in the carbon-fixing mesh frame 301 further filters and adsorbs; finally, in the return air duct 4, the air guide hood 21 guides the air to fully contact the negative ion generator 5, purifying the air, and the airflow sensor 6 monitors the airflow in real time. When the airflow is less than the set threshold, it is determined to be blocked, which facilitates the disassembly and replacement of the primary filter 7, medium-efficiency filter 8, and high-efficiency filter 9. At the same time, the activated carbon particles can be replaced by removing the upper cover plate 302 and the lower cover plate 303, and the diamond-shaped protrusions 13 on the column rod 12 are used to stir the new activated carbon particles to reduce the gaps. This device enables multi-stage air purification, intelligent blockage monitoring, and convenient consumable replacement, improving the air quality and maintenance convenience of ship air conditioning return air and effectively solving the problems of air purification, blockage monitoring, and replacement in ship air conditioning return air.
