[0020] 2. While the arc-shaped sealing plate is sealing the inside of the filter cartridge, the top ring installed on the top of the guide rod will abut against the inclined surface of the arc-shaped guide ring. As the turntable continues to rotate, the arc-shaped guide ring will squeeze the guide rod to squeeze the scraper downward, so that the scraper can scrape off the impurities adhering to the inner wall of the filter cartridge. The scraped impurities will fall into the receiving box for collection, so as to automatically clean the filter cartridge and prevent impurities from clogging the filter holes and affecting the filtering effect of the filter holes.

A filter cylinder 8 is rotatably installed on the upper surface of the turntable 5 near the plurality of through holes 7. Half of the outer surface of the filter cylinder 8 A plurality of filter holes 9 are provided through the circumference, and an arc-shaped sealing plate 10 is fixedly installed on the upper surface of the turntable 5 near the filter cartridge 8. The arc-shaped sealing plate 10 is in contact with the outer surface of the filter cartridge 8, and a sealing ring is installed around the inner wall of the arc-shaped sealing plate 10. The sealing ring is against the surface of the filter cartridge 8, which can not only seal the filter cartridge 8, but also limit the position of the filter cartridge 8 to prevent the filter cartridge 8 from rotating at will; a rotating mechanism is provided between the end cover 2 and the filter cartridge 8, and the rotating mechanism includes a transmission gear 13 fixedly installed on the top of the filter cartridge 8, and the top wall of the end cover 2 is evenly fixed in the circumferential direction. A plurality of fixing rods 14 are installed, and an incomplete inner tooth ring 15 is fixedly installed at the bottom end of the plurality of fixing rods 14.

[0032] The drive motor 11 drives the transmission shaft 12 to rotate, so that the transmission shaft 12 drives the turntable 5 to rotate, and the turntable 5 can drive multiple filter cartridges 8 to rotate. When the filter cartridge 8 rotates to the incomplete outer tooth ring 17, the transmission gear 13 installed on the top of the filter cartridge 8 will engage with the incomplete outer tooth ring 17, so that the transmission gear 13 can drive the filter cartridge 8 to rotate 180 degrees clockwise while rolling on the incomplete outer tooth ring 17, so that the filter hole 9 opened on the filter cartridge 8 rotates to the side of the arc-shaped sealing plate 10, so that the arc-shaped sealing plate 10 can seal the filter cartridge 8, and prevent the gas inside the purification cartridge 1 from flowing to the discharge port 23 through the filter hole 9, causing the impurities collected in the receiving box 24 to be blown up and adhere to the inner wall of the filter cartridge 8 again, affecting the cleaning effect of the impurities on the inner wall of the filter cartridge 8.

The reset spring 21 is arranged between the lower surface of the top ring 20 and the top of the filter cartridge 8. After the top ring 20 is separated from the arc-shaped guide ring 22, the reset spring 21 will push the top ring 20 to move upward, thereby resetting the scraper 19, so that the filter cartridge 8 can filter the external gas.

[0034] A method for using a construction air dust reduction device comprises the following steps:

[0035] S1: Connect the air inlet pipe 3 installed on the purification cylinder 1 to the exhaust end of the external exhaust fan, so that the external exhaust fan sucks the dust-containing air generated during construction into the purification cylinder 1 through the air inlet pipe 3;

[0036] S2: The gas flows through the corresponding filter cartridge 8, so that the filter cartridge 8 filters the air containing dust through the filter holes 9 opened on the outer surface thereof;

[0037] S3: The drive motor 11 drives the transmission shaft 12 to rotate, so that the transmission shaft 12 drives the turntable 5 to rotate, and the turntable 5 can drive multiple filter cartridges 8 to rotate. When the filter cartridge 8 rotates to the incomplete outer tooth ring 17, the transmission gear 13 installed on the top of the filter cartridge 8 will engage with the incomplete outer tooth ring 17, so that the transmission gear 13 can drive the filter cartridge 8 to rotate 180 degrees clockwise while rolling on the incomplete outer tooth ring 17, so that the filter hole 9 opened on the filter cartridge 8 rotates to the side of the arc-shaped sealing plate 10, so that the arc-shaped sealing plate 10 can seal the filter cartridge 8, thereby preventing the gas inside the purification cartridge 1 from flowing to the discharge port 23 through the filter hole 9, causing the impurities collected in the receiving box 24 to be blown up.

[0038] When the top ring 20 installed on the top of the guide rod 18 will abut against the inclined surface of the arc-shaped guide ring 22, as the turntable 5 continues to rotate, the arc-shaped guide ring 22 will squeeze the guide rod 18 to squeeze the scraper 19 downward, so that the scraper 19 can scrape off the impurities adhered to the inner wall of the filter cylinder 8. The scraped impurities will fall into the receiving box 24 for collection, so as to automatically clean the filter cylinder 8 and prevent the impurities from clogging the filter holes 9 and affecting the filtering effect of the filter holes 9.

[0039] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the exhaust pipe 4 installed on the end cover 2 is connected to the air inlet end of the indoor ventilation duct, and the air inlet pipe 3 installed on the purification cylinder 1 is connected to the external gas, so that the external gas enters the purification cylinder 1 through the air inlet pipe 3. Since the baffle 6 is installed at the bottom of the purification cylinder 1, the incoming gas can flow through the corresponding filter cylinder 8, so that the filter cylinder 8 can filter the dust-containing air through the filter holes 9 opened on its outer surface, and the filtered impurities adhere to the inner wall of the filter cylinder 8. The filtered gas will be discharged through the exhaust pipe 4, so as to achieve the dust reduction and purification effect of the dust-containing air during construction;

[0040] When filtering external gas, the transmission shaft 12 is driven to rotate by the driving motor 11, so that the transmission shaft 12 drives the turntable 5 to rotate, and the turntable 5 can drive multiple filter cartridges 8 to rotate. When the filter cartridge 8 rotates to the incomplete outer tooth ring 17, the transmission gear 13 installed on the top of the filter cartridge 8 will mesh with the incomplete outer tooth ring 17, so that the transmission gear 13 can drive the filter cartridge 8 to rotate 180 degrees clockwise while rolling on the incomplete outer tooth ring 17, so that the filter hole 9 opened on the filter cartridge 8 is rotated to the side of the arc-shaped sealing plate 10, so that the arc-shaped sealing plate 10 can seal the filter cartridge 8, and prevent the gas inside the purification cartridge 1 from flowing to the discharge port 23 through the filter hole 9, causing the impurities collected in the receiving box 24 to be blown up and adhere to the inner wall of the filter cartridge 8 again, affecting the cleaning effect of the impurities on the inner wall of the filter cartridge 8;

[0041] While the arc-shaped sealing plate 10 is sealing the inside of the filter cartridge 8, the top ring 20 installed on the top of the guide rod 18 will abut against the inclined surface of the arc-shaped guide ring 22. As the turntable 5 continues to rotate, the arc-shaped guide ring 22 will squeeze the guide rod 18 to squeeze the scraper 19 downward, so that the scraper 19 can scrape off the impurities adhering to the inner wall of the filter cartridge 8. The scraped impurities will fall into the receiving box 24 for collection, so as to automatically clean the filter cartridge 8 and prevent the impurities from clogging the filter holes 9 and affecting the filtering effect of the filter holes 9.

[0042] After the inner wall of the filter cartridge 8 is cleaned, as the turntable 5 drives the filter cartridge 8 to continue to rotate, the transmission gear 13 installed on the top of the filter cartridge 8 engages with the incomplete internal tooth ring 15, and the transmission gear 13 rolls on the incomplete internal tooth ring 15, thereby driving the filter cartridge 8 to rotate 180 degrees counterclockwise to reset, exposing the filter hole 9, so as to continuously filter the air containing dust.

[0043] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
