Sewage treatment screw sludge press dewatering machine is operated by means of screw extrusion, strong pressing force generated by screw diameter and pitch change, and small gap between swimming ring and fixed ring to realize sludge a new type of solid-liquid separation equipment for extrusion dewatering. 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.
In the structural design, the front part of the sewage treatment screw sludge press dewatering machine is the enrichment part, and the rear part is the dewatering part. The concentration of the mud and the dewatering work of the crushing are completed together, replacing the traditional filter cloth and centrifugal filtration with a unique and delicate mode.
Dewatering principle of sewage treatment screw sludge press dewatering machine:
After the sludge is concentrated by gravity in the enrichment section, it is transported to the dehydration section, and the resistance and the pitch gradually decrease during the advancement process, and the resistance of the back pressure plate Underneath, a great internal pressure is generated, and the volume is continuously reduced to achieve the purpose of sufficient dehydration.
