Construction principle and dehydration principle of screw sludge dewatering machine

- Oct 31, 2018-

The screw sludge dewatering machine has the advantages of good performance, high work efficiency, high degree of automation, economical price and long service life. The machine uses the principle of screw extrusion, a powerful pressing force generated by the change of screw diameter and pitch, and a small gap between the swimming ring and the fixed ring to realize a new type of solid liquid for sludge dewatering and dewatering. Separate the device.


From the structural point of view, the front part of the screw sludge dewatering machine is a concentrated part, and the rear part is a dewatering part. The main body of the machine is composed of a plurality of fixing rings and a swimming ring through which the screw shaft is formed. During the operation, the sludge is concentrated by gravity in the enrichment section and transported to the dehydration section. During the advancement process, as the filter joint and the pitch become smaller, and the back pressure plate blocks, the sludge is greatly generated. The internal pressure and the volume are continuously reduced to achieve the purpose of sufficient dehydration.


With its unique dehydration principle and advantages, the screw sludge dewatering machine is quickly used in sludge dewatering in municipal wastewater, food, beverage, slaughtering, printing and dyeing, petrochemical, paper, leather, pharmaceutical and other industries.
