The working process of the dried sludge part is as follows:

first, the drive motor is started to keep the lower rotating roller 55, the upper rotating roller 56, and the drive belt 57 rotating at a low speed and at a constant speed.

Then, the filtrate is introduced into the filtrate inlet pipe 54, and the filtrate is introduced into the liquid inlet tank 51.

Then, as the elastic blade 58 is rotated out of the liquid inlet tank 51, the filtered material is attached to one side of the elastic blade 58, and as shown in fig. 1, the upper rotating roller 56 rotates counterclockwise, the right elastic blade 58 moves upward, and a wet film is formed on the elastic blade 58.

Finally, the dried elastic scraper 58 rotates to the left side along with the rotation of the driving belt 57, hot air passes through a hot air zone to exchange heat, so that the filter on the elastic scraper 58 is dried, the elastic scraper 58 vertically moves downwards, the elastic scraper 58 slides to the groove stop 53, the elastic scraper 58 deforms along with the elastic scraper, and the dried sludge is scraped into the dried sludge groove 52.
