Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically an air intake filter that is easy to clean. Background Technology

[0002] The main function of an intake filter is to remove impurities from the medium to protect valves and equipment. Its working principle is primarily based on the filtering effect of the filter screen. After airflow enters the filter, it is filtered by the screen, and impurities are blocked on the outside of the screen, while clean airflow continues to flow through the screen.

[0003] After installing the intake filter at the inlet of the required equipment, start the equipment. Gas will begin to pass through the intake filter, which will filter out impurities in the gas. The filtered clean gas will then flow to the outside from the outlet pipe of the intake filter.

[0004] Through long-term use and observation, it was found that during the dust removal process using the air intake filter, excessive dust accumulation inside the filter weakens its ability to capture particulate matter in the airflow, thereby reducing filtration efficiency.

[0005] Therefore, this utility model provides an air intake filter that is easy to clean. Utility Model Content

[0006] To overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, an easy-to-clean intake filter is proposed.

The system includes a water spray pipe with an inclined structure; a dust collection box that slides on the side wall of the filter cartridge; a corresponding dust collection box and a water storage tank; a handle fixed to the middle of the side wall of the dust collection box; a circulation component fixed between the dust collection box and the water storage tank; and a water storage tank, a fixed cylinder, a movable cylinder, a water spray pipe, a dust collection box, and a circulation component connected together. This step, by setting up the water storage tank, fixed cylinder, movable cylinder, water spray pipe, dust collection box, and handle, allows suspended particulate matter in the airflow to be flushed into the dust collection box by water spray, thereby reducing the dust concentration in the airflow. The detachable dust collection box allows for the centralized collection of liquid carrying suspended particulate matter, facilitating subsequent processing and cleaning, reducing the diffusion of dust and liquid inside the air intake filter, and maintaining the cleanliness of the air intake filter's interior. By setting up the fixed cylinder, movable cylinder, and water spray pipe, dust in all areas inside the air intake filter can be effectively treated, reducing dust suppression blind spots and improving overall dust suppression efficiency.

[0012] Preferably, an atomizing nozzle is fitted in the middle of the side wall of the water spray pipe; the atomizing nozzle is located inside the filter cartridge; this step, by setting the atomizing nozzle, can decompose water molecules into tiny particles to form water mist, allowing it to come into more full contact with suspended particles in the airflow, increasing the probability of collision and adsorption, thereby more effectively removing dust from the airflow.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 4As shown, an easy-to-clean air filter according to an embodiment of the present invention includes a filter cartridge 1; an air inlet pipe 11 is fixed to the middle of the side wall of the filter cartridge 1; an air outlet pipe 12 is fixed to the middle of the side wall of the filter cartridge 1; the filter cartridge 1, the air inlet pipe 11, and the air outlet pipe 12 are all hollow and connected; a housing 13 is assembled to the middle of the side wall of the filter cartridge 1; the housing 13 covers the outside of the filter cartridge 1; a dust-suppressing component is provided to the middle of the side wall of the housing 13; a circulation component is provided to the middle of the side wall of the housing 13; the circulation component and the dust-suppressing component are connected; a filter screen 14 is slidably fitted to the middle of the side wall of the filter cartridge 1; both the filter screen 14 and the dust-suppressing component have limiting components to the middle of their side walls; a drying component is provided to the middle of the side wall of the housing 13; during operation, the operator places the air inlet pipe 11 and the filter to be filtered... The air intake port of the equipment is tightly connected, and the air outlet pipe 12 is connected to the exhaust fan. Then the exhaust fan is turned on, and the exhaust fan will drive the airflow from the air intake port of the equipment to be filtered into the air inlet pipe 11. At this time, the airflow will carry the suspended particles into the inside of the filter cartridge 1. Then the dust suppression component is activated. The dust suppression component sprays water onto the suspended particles to make the particles settle down. At this time, the dust-removed airflow will enter the drying area. The operator activates the drying component, which dries the humid airflow, so that the dried airflow passes through the filter screen 14 and flows out of the air outlet pipe 12 to the outside of the filter cartridge 1. After the dust removal is completed, the operator releases the limiting component and removes the filter screen 14 and the dust suppression component from the inside of the filter cartridge 1 for cleaning.

[0026] like Figures 1 to 3As shown, the dust suppression assembly includes a water storage tank 2; the water storage tank 2 is fixed to the side wall of the filter cartridge 1 and the housing 13; multiple fixed cylinders 21 are fixedly connected to the middle of the side wall of the water storage tank 2; a movable cylinder 22 is rotatably connected to the middle of the inner side wall of the fixed cylinder 21; multiple water spray pipes 23 are fixedly connected to the middle of the side wall of the movable cylinder 22; the water spray pipes 23 are arranged with an inclined structure; a dust collection box 24 is slidably fitted on the side wall of the filter cartridge 1; the dust collection box 24 and the water storage tank 2 are correspondingly arranged; a handle 25 is fixed to the middle of the side wall of the dust collection box 24; a circulation assembly is fixed to the dust collection box 24 and the water storage tank 2. Between water tanks 2; water storage tank 2, fixed cylinder 21, movable cylinder 22, spray pipe 23, dust collection box 24 and circulation assembly are connected; when the airflow carrying suspended particles enters the filter cartridge 1 from the air inlet pipe 11, the operator starts the circulation assembly, which will transport water to the water storage tank 2. Because the water storage tank 2, fixed cylinder 21, movable cylinder 22 and spray pipe 23 are connected, the liquid will enter multiple fixed cylinders 21 and flow into the movable cylinder 22, and then be sprayed onto the flowing airflow from multiple spray pipes 23. Suspended particles inside the airflow will fall downwards upon contact with water and eventually be collected inside the dust collection box 24. Because the fixed cylinder 21 and the movable cylinder 22 are rotatably connected, when water is sprayed outwards through multiple inclined spray pipes 23, it will drive the movable cylinder 22 to rotate on the inner wall of the fixed cylinder 21, causing the sprayed liquid to rotate inside the filter cartridge 1. This step, with the water storage tank 2, fixed cylinder 21, movable cylinder 22, spray pipes 23, dust collection box 24, and handle 25, can flush suspended particles in the airflow into the dust collection box 24 through precipitation, thereby reducing the dust concentration in the airflow. The detachable dust collection box 24 allows the liquid carrying suspended particles to be collected centrally, facilitating subsequent processing and cleaning, reducing the diffusion of dust and liquid inside the air intake filter, and keeping the air intake filter clean. By setting up the fixed cylinder 21, movable cylinder 22, and spray pipes 23, dust in all areas inside the air intake filter can be effectively treated, reducing dust blind spots and improving overall dust reduction efficiency.

[0027] like Figures 1 to 4As shown, the limiting assembly includes multiple slots 3; the multiple slots 3 are respectively opened on the side walls of the filter cartridge 1, filter screen 14, and dust collection box 24; a limiting rod 31 is slidably engaged in the middle of the inner side wall of the slot 3; a pair of limiting plates 32 are slidably engaged in the middle of the side wall of the limiting rod 31; a handle 33 is fixed in the middle of the side wall of the limiting plate 32; when the dust collection box 24 is full of wet suspended particles, the operator pulls the pair of handles 33. At this time, the handles 33 will drive the limiting plate 32 to slide along the surface of the multiple limiting rods 31, and then disengage from the limiting rods 31, thus pulling the multiple limiting rods 31 out of the dust collection box 24, at which point it can be easily removed. Song removes and cleans the dust collection box 24 from inside the filter cartridge 1. Similarly, the filter screen 14 can also be removed and cleaned from inside the filter cartridge 1. This step, through the setting of slot 3, limit rod 31, limit plate 32 and handle 33, allows the operator to easily remove the dust collection box 24 and filter screen 14 from inside the filter cartridge 1 for cleaning or replacement. This simplifies the cumbersome process of traditional air intake filters that require complete disassembly and complex cleaning. Furthermore, by regularly cleaning or replacing the dust collection box 24 and filter screen 14, the air intake filter can continue to operate efficiently, which helps to reduce the performance degradation and energy consumption caused by air intake filter clogging.

[0028] like Figures 1 to 4 As shown, the drying component includes multiple grooves 4; multiple grooves 4 are evenly distributed on the side wall of the housing 13; a connecting support 41 is fixedly connected to the middle of the side wall of the housing 13; a power cord 43 is assembled in the middle of the side wall of the connecting support 41; multiple infrared drying lamps 42 are installed in the middle of the side wall of the connecting support 41; multiple infrared drying lamps 42 are located inside the grooves 4; when the airflow after dust removal flows to the drying area inside the filter cartridge 1, the operator turns on the power cord 43, at which time multiple infrared drying lamps 42 start to work, continuously drying the gas flowing towards the filter screen 14. This step, by setting up the grooves 4, connecting support 41, infrared drying lamps 42 and power cord 43, can quickly remove moisture from the airflow, reduce the humid airflow, reduce the filtration efficiency of the intake filter, and even cause the filter screen 14 to become clogged. Moreover, the long-term humid environment inside the intake filter will promote corrosion and microbial growth, causing damage to the intake filter and the entire system. This setting helps to improve the stability and reliability of the entire system.

[0029] like Figure 1 and Figure 3As shown, the circulation component includes a water pump 5; the water pump 5 is fixed on the side wall of the housing 13; the water outlet end of the water pump 5 is fixedly connected to a water outlet pipe 51; the water pump suction end of the water pump 5 is fixedly connected to a water suction pipe 52; the water outlet pipe 51 is connected to the water storage tank 2; the water suction pipe 52 is connected to the dust collection box 24; when working, the operator starts the water pump 5, and the water pump 5 will draw the liquid filtered inside the dust collection box 24 into the water outlet pipe 51 through the water suction pipe 52, and then flow back into the water storage tank 2 through the water outlet pipe 51. This step of setting up the water pump 5, the water outlet pipe 51 and the water suction pipe 52 can reduce water waste by recycling water resources and further achieve energy saving effect.

[0030] like Figure 2 and Figure 4 As shown, multiple water guide plates 6 are fixed in the middle of the inner wall of the filter cartridge 1; the water guide plates 6 are set with an inclined structure; by setting multiple inclined water guide plates 6, water molecules splashed onto the surface of the water guide plates 6 can be guided to the inside of the dust collection box 24, preventing liquid from wetting the dry area inside the air intake filter, and further reducing the possibility of bacterial growth.

[0031] like Figure 2 As shown, an atomizing nozzle 7 is installed in the middle of the side wall of the water spray pipe 23; the atomizing nozzle 7 is located inside the filter cartridge 1; this step, by setting the atomizing nozzle 7, can decompose water molecules into tiny particles to form water mist, so that it can come into more full contact with suspended particles in the airflow, increasing the chance of collision and adsorption, thereby more effectively removing dust in the airflow.

[0032] Working principle: The operator tightly connects the air inlet pipe 11 to the air intake of the equipment to be filtered, and simultaneously connects the air outlet pipe 12 to the exhaust fan. The exhaust fan is then turned on, drawing airflow from the air intake of the equipment to be filtered into the air inlet pipe 11. This airflow carries suspended particulate matter into the filter cartridge 1. The dust suppression component is then activated, spraying water onto the suspended particulate matter to cause it to settle. The dust-removed airflow then enters the drying zone, where the operator activates the drying component. This component dries the moist airflow, allowing the dried airflow to pass through the filter screen 14. The air flows from the outlet pipe 12 to the outside of the filter cartridge 1. After dust removal is completed, the staff releases the limiting component, removes the filter screen 14 and dust collection component from the inside of the filter cartridge 1 and cleans them. When the airflow carrying suspended particles enters the filter cartridge 1 from the inlet pipe 11, the staff activates the circulation component, which delivers water to the water storage tank 2. Because the water storage tank 2, fixed cylinder 21, movable cylinder 22 and spray pipe 23 are connected, the liquid enters multiple fixed cylinders 21 and flows into the movable cylinder 22, and is then sprayed onto the flowing airflow from multiple spray pipes 23. When suspended particulate matter in the filter cartridge 1 comes into contact with water, it will fall downwards and eventually fall into the dust collection box 24, where it will be collected. Because the fixed cylinder 21 and the movable cylinder 22 are rotatably connected, when water is sprayed outwards through multiple inclined spray pipes 23, it will cause the movable cylinder 22 to rotate on the inner wall of the fixed cylinder 21, causing the sprayed water to rotate inside the filter cartridge 1. When the dust collection box 24 is full of wet suspended particulate matter, the operator pulls a pair of handles 33. At this time, the handles 33 will cause the limiting plate 32 to slide along the surface of multiple limiting rods 31, and then disengage from the limiting rods 31, thus moving the multiple limiting rods 31 towards the surface of the filter cartridge 1. The lever 31 is pulled out of the dust collection box 24, at which point the dust collection box 24 can be easily removed from the filter cartridge 1 for cleaning. Similarly, the filter screen 14 can also be removed from the filter cartridge 1 for cleaning. When the airflow after dust removal flows to the drying area inside the filter cartridge 1, the operator connects the power cord 43. At this time, multiple infrared drying lamps 42 start working, continuously drying the gas flowing towards the filter screen 14. The operator starts the water pump 5, which draws the filtered liquid inside the dust collection box 24 into the water outlet pipe 51 through the water suction pipe 52, and then flows back into the water storage tank 2 through the water outlet pipe 51.
