A sludge inlet is provided at the upper end of the thickening section, and a sludge outlet is provided at the bottom of the dewatering section. After the sludge is concentrated by gravity in the thickening section, it is transported to the dewatering section. In the process of moving forward, as the filter gap and the screw pitch gradually become smaller, and under the blocking effect of the back pressure plate, a huge internal pressure is generated, and the volume continues to shrink, thereby achieving the purpose of sufficient dehydration.

[0003] The Chinese utility model patent with publication number CN218969063U in the prior art proposes a screw stacking sludge dewatering machine. When the dewatering machine is working, the screw rotates in the screw stacking sludge dewatering machine, and the screw drives the stirring mechanism and the pressing mechanism to operate. After the sludge is input into the sludge inlet hopper through the pipeline, the stirring mechanism breaks up the lumps in the sludge and separates the hard large particles in the sludge from the sludge.
