[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

Similarly, words such as "one" or "a" do not indicate a quantity limitation, but rather indicate the existence of at least one. Words such as "connected" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0042] First, the dust-proof filtering device for a ship ventilation duct according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Specifically, if Figures 1 to 3 As shown, the dust-proof filtering device for a ship ventilation duct according to an embodiment of the present invention may include: a filter chamber 100 , a filter screen 600 and an aeration assembly 700 .

[0044] The filter chamber 100 has an accommodating cavity formed therein, an air inlet 200 formed on the side and an air outlet 300 formed at the upper end, a water inlet 400 formed at the upper end and a drain outlet 500 formed at the bottom.

[0045] The filter 600 is disposed in the accommodating chamber to partition the accommodating chamber into a first chamber located at an upper portion and a second chamber located at a lower portion in a height direction, wherein the second chamber is communicated with the air inlet 200 and the first chamber is communicated with the air outlet 300 .

[0046] The aeration component 700 is disposed in the second chamber. The air inlet end of the aeration component 700 is communicated with the air inlet 200 and the air outlet direction is toward the filter 600 .

[0047] Specifically, according to an embodiment of the present invention, a dust-proof filter device for a ship ventilation duct includes a filter chamber 100, within which a housing cavity is provided to accommodate a filter screen 600 and an aeration assembly 700. An air inlet 200 is formed on the side of the filter chamber 100, and an air outlet 300 is formed at the top. The filter chamber 100 also includes a water inlet 400 at the top and a water outlet 500 at the bottom. The filter screen 600 is disposed within the housing cavity, dividing the housing cavity vertically into a first chamber located at the top and a second chamber located at the bottom. The second chamber is connected to the air inlet 200, and the first chamber is connected to the air outlet 300. During use, tap water is injected into the filter chamber 100 from above, passes through the filter screen 600, the aeration assembly 700, and is ultimately discharged through the water outlet 500 at the bottom. At the same time, the aeration component 700 is arranged in the second chamber, and the air inlet end of the aeration component 700 is connected to the air inlet 200 and the air outlet direction is toward the filter 600, that is, the gas flows in from the air inlet 200, passes through the filter 600, and finally flows out from the air outlet 300 at the upper end. Thus, the gas is filtered by the filter 600 to remove impurities therein. That is to say, when ventilation and filtration are performed, aeration in water is performed, which not only can remove part of the dust in the air, but also the aeration component 700 generates a large number of tiny bubbles and discharges them into the tap water in the filter chamber 100, so that some tiny particles in the gas will be wetted by the water and mixed into the water, thereby filtering out some tiny particles. At the same time, the air is flushed by the water flowing down from the filter 600 to increase the humidity, and then the bubbles float up and contact the filter 600, and are then filtered by the filter 600. During this period, many bubbles adhere to the lower surface of the filter 600 and pass through the filter 600. At the same time Debris in the air will also be filtered on the lower surface of the filter 600, and the debris filtered out from the lower surface will be washed down by the action of water wetting and the impact force of the rising bubbles. During the period of inactivity, the tap water flow is left to stand, which can settle the debris under the accommodating cavity, thereby avoiding clogging of the mesh of the filter 600. This can avoid the trouble of frequent cleaning and maintenance of the filter 600, making the entire ventilation and filtration process simpler and more efficient, and at the same time can humidify the filtered gas, further improving the convenience and practicality of the dust-proof filter device for ship ventilation ducts.

[0048] In some embodiments of the present invention, the filter screen 600 is formed in an inverted frustum shape.

[0049] The inverted frustum-shaped structure helps water flow, form vortices, and flush the lower surface; and this structure increases the filtering area and improves the filtering efficiency of the dust-proof filter device for ship ventilation ducts.

[0050] In some embodiments of the present invention, the aeration assembly 700 includes a first aeration mechanism 710 , and the first aeration mechanism 710 includes a first air inlet pipe 711 and one or more first aerators 712 .

[0051] One end of the first air inlet pipe 711 is connected to the air inlet 200, thereby receiving fresh air from the outdoor air supply blower through the air inlet 200. The first aerator 712 is connected to the first air inlet pipe 711 and is in air communication with the first air inlet pipe 711. In other words, the first air inlet pipe 711 draws air from the air inlet 200 into the first aerator 712 located below the filter 600. The first aerator 712 then delivers the air to the filter 600 for filtration and discharges it from the air outlet 300 above.

[0052] In some embodiments, as Figures 2 to 3 As shown, there are multiple first aerators 712. The first aeration mechanism 710 also includes a first diverter ring 713 and a first support rod 714. The first diverter ring 713 is connected to the other end of the first air inlet pipe 711. The multiple first aerators 712 are evenly spaced and distributed on the first diverter ring 713. The first support rod 714 is connected to the first diverter ring 713 at one end and to the sidewall of the filter chamber 100 at the other end to support the first aeration mechanism 710 and provide a more secure structure.

[0053] According to this embodiment, by providing multiple first aerators 712, a large number of small bubbles are formed through the aeration assembly, thereby increasing the contact area between gas and water and achieving a better aeration effect. Furthermore, after air is diverted by the first diverter ring 713, it is aerated from different directions below the filter 600 through the multiple evenly spaced first aerators 712, effectively removing debris from the lower surface of the filter 600. Furthermore, in actual use, the gas flow rate is very high, and the provision of the first diverter ring reduces air resistance, allowing gas to evenly enter each first aerator for aeration.

[0054] In some embodiments of the present invention, the aeration assembly 700 also includes a second aeration mechanism 720, which is located below the first aeration mechanism 710. The second aeration mechanism 720 includes: a second air inlet pipe 721 and one or more second aerators 722. One end of the second air inlet pipe 721 is connected to the air inlet 200, and the air inlet 200 receives air delivered by an outdoor air supply fan; the second aerator 722 is connected to the second air inlet pipe 721 and is in air communication with the second air inlet pipe 721.

[0055] That is, in addition to the first aeration mechanism 710, a second aeration mechanism 720 is also provided below it, thereby enabling aeration to be more evenly directed toward the lower surface of the filter screen 600, thereby improving the flushing efficiency of the lower surface and the gas filtration efficiency.

[0056] In some embodiments, as Figures 2 to 3 As shown, there are multiple second aerators 722, and the second aeration mechanism 720 also includes: a second diverter ring 723 and a second support rod 724. The projection of the second diverter ring 723 in the vertical direction is located on the outside of the first diverter ring 713, and the second diverter ring 723 is connected to the other end of the second air inlet pipe 721; multiple second aerators 722 are evenly spaced and distributed on the second diverter ring 723; one end of the second support rod 724 is connected to the second diverter ring 723 and the other end is connected to the side wall of the filter bin 100 to support the second aeration mechanism 720, making the device more firm. Thus, by providing the second diverter ring 723, air is diverted, and since its gas flow rate is very large in actual use, providing the diverter ring can reduce air resistance. In addition, by evenly distributing multiple second aerators 722 on the second diverter ring 723, more gas can be evenly introduced into each second aerator 722 to react with the aeration solution for aeration; and, by making the vertical projection of the second diverter ring 723 located outside the first diverter ring 713, multiple layers of independent first aerators 712 and second aerators 722 are provided from top to bottom, so that the lower surface of the filter screen 600 can be aerated more evenly from different directions, which not only improves the debris removal effect of the filter screen 600, but also helps to improve the gas filtration efficiency.

[0057] It should be noted that the specific structure of the aerator (including the first aerator 712 and the second aerator 722) is not limited in this application. As long as the aerator can solve the problem of filter clogging and cleaning, it can be used. For example, it can be an underwater aerator such as a microporous aerator or a jet aerator, or a tubular aerator, a disc aerator, a diaphragm aerator, etc. Specifically, the aerator can be selected based on the actual characteristics of the filter 600, water pressure, air flow rate and flow rate, machine usage and maintenance frequency, etc.

[0058] In some embodiments of the present invention, the first aerator 712 and / or the second aerator 722 are disc aerators, which can ensure energy-saving design, low installation cost, high reliability, excellent performance, and convenient precision drilling during intermittent and continuous aeration. In addition, the use of precision drilling for the diaphragm in the disc aerator is conducive to efficient oxygen transmission and utilization. In order to meet the specifications of the aeration system, different drilling patterns can be used to adjust the working pressure, such as different slit lengths, distances, and drilling densities. For example, in the use scenario of the present application, that is, dust filtration for ship ventilation ducts, the drilling diameter can be set between 184 and 295 mm. In some embodiments of the present invention, the aeration assembly 700 also includes:

[0059] Docking plate 730 is connected to air inlet 200 and has a first connecting hole and a second connecting hole formed therein. One end of first air inlet pipe 711 is connected to the first connecting hole, and one end of second air inlet pipe 721 is connected to the second connecting hole. The addition of docking plate 730 secures the first and second connecting holes, preventing damage to the air inlet pipe from excessive wind from the blower, making the entire device more stable and extending its service life.

[0060] In some embodiments of the present invention, isolation hopper 800 is formed in an inverted triangular cone shape and is disposed within the second chamber and below aeration assembly 700. A discharge port is formed below isolation hopper 800 to provide communication between the upper and lower portions of isolation hopper 800. The provision of isolation hopper 800 allows dust in tap water to settle below it when the filter is not operating. Furthermore, when the filter is operating, debris below isolation hopper 800 is prevented from disturbing the filtration process.

[0061] In some embodiments of the present invention, the gas outlet 300 is connected to a plurality of branch pipes for delivering gas to different compartments, thereby allowing each compartment to receive filtered air and avoiding the disadvantage of uneven delivery of filtered gas.

[0062] In some embodiments of the present invention, the drain port 500 is connected to a solenoid valve 510, and the water inlet 400 is connected to an openable / closable sealing cap 410. Thus, dust and impurities filtered out by the filter device can be discharged more quickly through the solenoid valve 510, and the spiral-sealed sealing cap 410 attached to the water inlet 400 can also be closed when water is not being injected, thereby preventing contamination and enhancing the airtightness of the device. Of course, this is not limited to this.

[0063] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
