A fourth water pipe 420 is fixedly provided on the outer surface of the second water pipe 402, and a third horizontal water pipe is fixedly installed at the other end of the fourth water pipe 420. One end of the first water pipe 401 away from the water pump 403 is fixedly installed with a third horizontal water pipe parallel to the bottom of the second conveyor belt 502. A number of spray nozzles 404 are fixedly installed on the outer surfaces of the first horizontal water pipe, the second horizontal water pipe, and the third horizontal water pipe. The number of spray nozzles 404 spray water to clean the sludge on the surfaces and the leakage holes of the first conveyor belt 501, the second conveyor belt 502, and the third conveyor belt 503.

A fourth conveyor belt 8 is provided inside the drying box 7. A feeding hopper 6 is provided above the fourth conveyor belt 8. The feeding hopper 6 can centrally convey the dewatered sludge.

[0028] Working principle: The sludge to be dewatered is fed in from the feed inlet 2. The sludge falls onto the first conveyor belt 501. Through the conveyance of the first conveyor belt 501, a large amount of sewage in the sludge leaks out from the leakage holes of the first conveyor belt 501 and flows onto the surface of the first scraper 510. At the same time, the first scraper 510 scrapes off a large amount of sludge remaining on the first conveyor belt 501. The sludge falls from the first conveyor belt 501 onto the second conveyor belt 502. During the falling process, the sludge can be further dewatered. The sewage leaks out through the leakage holes on the second conveyor belt 502 and flows onto the surface of the second scraper 520. At the same time, the second scraper 520 scrapes off a large amount of sludge remaining on the surface of the second conveyor belt 502. The sludge is conveyed by the second conveyor belt 502 and falls onto the third conveyor belt 503. Through the leakage holes of the third conveyor belt 503, the sewage in the sludge is further separated and flows onto the surface of the third scraper 530. At the same time, the third scraper 530 scrapes off the sludge adhering to the surface of the third conveyor belt 503. The dewatered sewage flows through the first scraper 510, the second scraper 520, and the third scraper 530 and into the filter screen 3 for filtration. The filtered water will flow into the bottom reservoir 9. The water in the reservoir 9 is respectively conveyed into the first water pipe 401 and the second water pipe 402. The second water pipe 402 conveys the water into the third water pipe 430 and the fourth water pipe 420. The water flows through the first water pipe 401, the third water pipe 430, and the fourth water pipe 420 and into the first horizontal water pipe, the second horizontal water pipe, and the third horizontal water pipe. It is sprayed out by several spray nozzles 404 on the first horizontal water pipe, the second horizontal water pipe, and the third horizontal water pipe to clean the sludge on the surfaces and leakage holes of the first conveyor belt 501, the second conveyor belt 502, and the third conveyor belt 503, improving the dewatering efficiency of the sludge. The sludge that has been dewatered of a large amount of sewage is conveyed by the third conveyor belt 503 into the feed hopper 6. The sludge flows through the feed hopper 6 and is concentrated onto the fourth conveyor belt 8. The fourth conveyor belt 8 conveys the sludge through the drying box 7 to further dry the remaining moisture.
