[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, the environmental protection engineering construction of this embodiment proposes a high-efficiency, energy-saving, environmentally friendly and self-cleaning air filter, including an air exchange channel 1, a filter frame 4, a deflection mechanism, a conveying mechanism and a cleaning mechanism. One side of the air exchange channel 1 is set as an air intake end 2, and the other side is set as a filter end 3. The air intake end 2 on the air exchange channel 1 is connected to the external air intake fan, and the air intake fan is used to drive the air flow through the filter frame 4 and then enter the air exchange channel 1. There are multiple filter frames 4, and multiple filter frames 4 are rotatably connected to the filter end 3. Adjacent filter frames 4 are in contact end to end. A filter is provided on the filter frame 4. There are two deflection mechanisms, and the two deflection mechanisms are respectively arranged on both sides of the filter end 3. The deflection mechanism is in contact with multiple filter frames 4, and the deflection mechanism is used to drive multiple filter frames 4 rotates, the conveying mechanism is arranged in the air intake end 2, and a cleaning mechanism is arranged on the conveying mechanism, which is used to drive the cleaning mechanism to contact the multiple filter frames 4, and the cleaning mechanism is used to clean the multiple filter frames 4 on the side close to the air intake end 2. When there are many impurities on the filter screen, the multiple filter frames 4 are rotated by the deflection mechanism, so that the side with dust attached is rotated to the side facing the air intake end 2. At this time, the conveying mechanism drives the cleaning mechanism close to the filter frame 4, and then drives the filter frame 4 to move, and cleans each position on the filter screen in turn. After cleaning, the cleaning mechanism is away from the filter frame 4, which does not affect the subsequent filtration. The filter screen can be used for single-sided filtering or double-sided filtering, and the service life of the filter screen can be improved while being able to be cleaned regularly.

[0020] like Figures 4 to 6As shown, multiple filter frames 4 are grouped in pairs. When two filter frames 4 are rotated to contact their edges, they can form a V shape. The edges of multiple groups of filter frames 4 are in contact with each other. Docking strips 21 are provided on both sides of the filter end 3. The filter frames 4 can contact with the docking strips 21. In this embodiment, eight filter frames 4 are provided, which are divided into four groups. The filter frames 4 can maintain two angles when rotating, both of which are inclined. The two sides of the filter are respectively facing one side of the filter end 3 on the ventilation channel 1. The edges of the filter frames 4 are in contact with the adjacent filter frames 4 at the two angles. At the same time, the edges of the two filter frames 4 on both sides are respectively in contact with the docking strips 21 on both sides, so that the airflow needs to pass through the filters on the eight filter frames 4 before entering the ventilation channel 1.

[0021] like Figures 5 and 6 As shown, the deflection mechanism includes a V-shaped extrusion piece 5, an extrusion groove 6, an extrusion frame 7 and a drive cylinder 8. There are multiple V-shaped extrusion pieces 5. Each filter frame 4 is fixedly connected to both sides of the filter end 3 for rotation. A V-shaped extrusion piece 5 is fixedly connected. The two V-shaped extrusion pieces 5 on each group of filter frames 4 are arranged in opposite directions. The extrusion groove 6 is fixedly connected to the filter end 3. The extrusion frame 7 is slidably arranged in the extrusion groove 6. The drive cylinder 8 is fixedly installed on the filter end 3. The output end of the drive cylinder 8 is fixedly connected to the extrusion frame 7. Both ends of the V-shaped extrusion piece 5 are set to be arc-shaped. The frame 7 squeezes the two ends of the V-shaped extrusion sheet 5 to rotate the V-shaped extrusion sheet 5. When the filter frame 4 remains tilted, the two opposite V-shaped extrusion sheets 5 form two openings on both sides, one large and one small. When the extrusion frame 7 squeezes the ends of the V-shaped extrusion sheet 5, the extrusion frame 7 contacts the side of the smaller opening, causing the small openings formed on the two V-shaped extrusion sheets 5 to rotate and open to form a large opening. The original large opening becomes a small opening, thereby causing the filter frame 4 to rotate. For ease of understanding, the large opening is marked with A and the small opening is marked with B.

[0022] like Figure 3 and Figure 6 As shown, the extrusion frame 7 is arranged in a mouth shape, and a plurality of V-shaped extrusion sheets 5 are arranged in the extrusion frame 7. Both ends of the V-shaped extrusion sheet 5 can contact the extrusion frame 7. When the extrusion frame 7 pushes the V-shaped extrusion sheet 5, the V-shaped extrusion sheet 5 can drive the filter frame 4 to rotate. The extrusion frame 7 surrounds the eight V-shaped extrusion sheets 5 on one side. When the driving cylinder 8 pushes the extrusion frame 7 to slide on the extrusion groove 6, the extrusion frame 7 can squeeze the ends of the V-shaped extrusion sheet 5.

[0023] like Figure 7As shown, the conveying mechanism includes a guide rod 9, a screw rod 10, a gear box 11 and a motor 12. There are multiple guide rods 9, and the multiple guide rods 9 are fixedly set on the suction end 2. There are two screw rods 10, and the two screw rods 10 are rotatably set on the suction end 2. There are two gear boxes 11, and the gear boxes 11 are fixedly installed on the suction end 2. The screw rods 10 and the gear boxes 11 correspond one to one, and the screw 10 and the gear boxes 11 are transmission connected. The motor 12 is fixedly installed on the suction end 2, and the two gear boxes 11 are both transmission connected to the output end of the motor 12. The output end of the motor 12 is transmitted and turned by the gear box 11, so that the two screw rods 10 are driven to rotate at the same time. The screw 10 pushes the cage frame 13 to rise and fall, thereby adjusting the height of the scraping assembly.

[0024] like Figure 3 and Figure 8 As shown, the cleaning mechanism includes a cage frame 13, an extension track 14, a drive cylinder 2 15 and a scraping assembly. The cage frame 13 is slidably set on the guide rod 9, and the two screws 10 are both threadedly connected to the cage frame 13. The extension track 14 is fixedly connected to the cage frame 13. There are multiple drive cylinders 2 15, and multiple drive cylinders 2 15 are fixedly installed on the cage frame 13. The scraping assembly is slidably connected to the extension track 14. The scraping assembly is used to scrape and clean the filter on the filter frame 4. When the output end of the motor 12 rotates, the two screws 10 can be driven to rotate respectively through the two gear boxes 11. The two screws 10 can drive the cage frame 13 to rise and fall, so that the scraping assembly slides on the filter frame 4 to scrape and remove the dust.

[0025] like Figures 5 to 8 As shown, the scraping assembly includes an air guide pipe 16, an air guide frame 17 and a scraping cone. The air guide pipe 16 runs through the air suction end 2, and the air guide pipe 16 is connected to the external fan. The air guide frame 17 is slidably connected to the extension track 14. The output end of the driving cylinder 2 15 is fixedly connected to the air guide frame 17, and the air guide pipe 16 is fixedly connected to the air guide pipe 16. There are multiple scraping cones, and the multiple scraping cones are fixedly connected to the air guide frame 17. The scraping cones are in contact with the filter screens on two adjacent filter frames 4, and air is inhaled through the external fan. The dust is scraped off and extracted after the scraping cone contacts the filter screen. The dust is filtered in the air guide pipe 16 through the filter screen behind the air guide pipe 16, or the dust is collected by the dust collection frame. At this time, the filter frame 4 rotates again and can be filtered again.

[0026] like Figure 8As shown, the scraping cone is provided with an upper cone plate 18, a lower cone plate 19 and a scraping strip 20, the upper cone plate 18 is fixedly mounted on the upper side of the air guide frame 17, the upper cone plate 18 is in contact with the filter frame 4, the lower cone plate 19 is fixedly mounted on the lower side of the air guide frame 17, a gap is left between the lower cone plate 19 and the filter frame 4, a gap is left between the upper cone plate 18 and the lower cone plate 19, a plurality of scraping strips 20 are provided, and a plurality of scraping strips 20 are provided on the lower cone plate 19. 20 is in contact with the filter on the filter frame 4. When scraping, the scraping cone moves from top to bottom, and the scraping bar 20 is in contact with the filter to scrape the collected dust and impurities on the filter. The air flow is sucked in through the filter and the gap between the lower cone plate 19 and the filter. The impurities are extracted in turn through the air guide frame 17 and the air guide pipe 16. A plate for scraping the filter is also provided on the side of the upper cone plate 18 close to the lower cone plate 19 to scrape off impurities that may not be scraped off.

[0027] In this embodiment, when the filter needs to be cleaned, the output end of the drive cylinder 1 8 is extended or shortened, driving the extrusion frame 7 to slide on the extrusion groove 6, and the inside of the extrusion frame 7 squeezes the end of the V-shaped extrusion sheet 5, so that the V-shaped extrusion sheet 5 rotates. At this time, the filter frame 4 rotates, so that the side of the filter frame 4 with dust attached is facing the suction end 2. At this time, the output end of the motor 12 drives the screw 10 to rotate, and the screw 10 drives the cage frame 13 to move to the upper position on the filter frame 4. The output end of the drive cylinder 2 15 pushes the air guide frame 17 to slide on the extension track 14, so that the upper cone plate 18 and the lower cone plate 19 contact the filter. At this time, the screw 10 drives the air guide frame 17 to move downward, the scraper 20 scrapes off the dust, and the fan extracts the dust through the air guide frame 17 and the air guide pipe 16.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
