[0028] In use, wastewater is fed into the right side of the rotating frame 24 inside the housing 3. The wastewater is filtered through the filter screen 2 on the rotating frame 24, and impurities remain on the surface of the filter screen 2 and the filter frame 11. At the same time, the motor b10 rotates, causing the connected rotating frame 24 to rotate counterclockwise. The rotation of the rotating frame 24 causes the connected multiple filter screens 2 to rotate. The continuous rotation of the filter screens 2 causes the impurities intercepted by the filter screens 2 to rotate counterclockwise as well. When the rotation continues to the left, the impurities intercepted by the filter screens 2 are thrown out and discharged to the left along the inclined guide frame 1. As the rotating frame 24 continues to rotate, the mesh plate 23 installed on the surface of the rotating frame 24 and the air blowing frame... Corresponding to the air inlet 25 of the air blowing frame 22, the high-pressure air pump 26 delivers high-pressure air into the air blowing frame 22 and blows it out through the air inlet 25.

After treatment, the water pump a9 is started to extract the partition a4 and the partition b5. Wastewater treated with flocculant is conveyed to the water delivery frame 6. The wastewater is then conveyed downwards to the surface of the filter cloth belt 7. Motor a8 rotates, driving shaft b20 to rotate. Shaft b20 rotates, causing the filter cloth belt 7 on the outside of the pulley to rotate to the right. The filter cloth belt 7 continuously filters the wastewater. The flocculent material intercepted by the filter cloth belt 7 moves upwards with the rotating filter cloth belt 7, passing through shaft a12. During continuous rotation, the scraper a13 at the top of the vertical plate a14 continuously scrapes the surface of the filter cloth belt 7, separating the flocculent material from the filter cloth belt 7 and conveying it along the scraper a13 into the vertical plate a14 and... Between the chambers 3, the filter cloth belt 7 is scraped and moved downwards by the guide roller 16. At this time, the filter cloth belt 7 is located in the cleaning chamber 15. The vibrator 17 at the bottom of the cleaning chamber 15 emits ultrasonic waves upwards, generating cavitation. After the cavitation bubbles generated on the surface of the filter cloth belt 7 break, they generate a large impact force, which can separate the residual flocs on the surface of the filter cloth belt 7 from the filter cloth belt 7. After separation, the filter cloth belt 7 continues to move past the scraper b18. The scraper b18 can scrape the surface of the filter cloth belt 7. After scraping, the filter cloth belt 7 continues to move to filter the sewage again. The filtered flocs can be cleaned while filtering.
