The fixed rod 54 rotates on the inner wall of the elliptical through-hole 53, thereby driving the connecting plate 52 to swing up and down, thereby driving the filter screen 51 to swing up and down in the installation box 2, so that the filter screen 51 filters the sludge, and large particles of impurities and garbage in the sludge will pass through the filter screen 51 and flow into the extraction groove 59 inside the rectangular box 58. At this time, the extraction groove 59 can be pulled out by the handle 50, and the large particles of impurities and garbage can be further processed or utilized, while the filtered sludge will continue to fall through the filter screen 51 for subsequent processing. This not only allows the sludge to be preliminarily screened before entering the subsequent processing link, but also facilitates the collection and processing of large particles of impurities and garbage, thereby improving the practicality of the device.

[0037] The sludge and water filtered by the filter screen 51 will fall into the installation cylinder 2 61 together through the two inclined plates 62. At this time, the stepper motor 3 67 is started, so that the stepper motor 3 67 drives the rotating shaft 3 66 to rotate, and then the auger 2 68 is rotated.
