Application of screw sludge dewatering machine in hospital sewage treatment

Sep 19, 2018

The general composition of hospital sewage is particularly complicated, and there are not many dewatering equipments that meet the processing requirements. However, the screw sludge dewatering machine is widely used in hospital sewage treatment, and is generally preferred as an integrated supporting equipment.


The screw sludge dewatering machine pushes the swimming ring by the rotation of the screw shaft to clean the gap of the filter portion to prevent clogging. From the enrichment section to the dehydration section, the diameter of the spiral shaft is gradually narrowed, and the diameter of the spiral shaft is gradually increased. The sludge is concentrated by gravity in the enrichment section and transported to the dehydration section, and the sludge is blocked by the pressure plate of the discharge port. The solid content rate is getting higher and higher, and the purpose of sludge dewatering is achieved.


The unique design makes the screw sludge dewatering machine suitable for any high and low concentration sludge dewatering, no clogging, easy to clean, no need to build flocculation tank, reduce construction cost; at the same time reduce the occupied land area, it is simple and convenient to use, fast and effective .


The screw sludge dewatering machine rotates 2-3 times per minute, the power consumption is very low, the operation is stable and no noise, and it will not cause secondary pollution. It is made of 304 stainless steel to extend the service life of the equipment. Basically, there is no need to replace the parts used in the equipment. The daily maintenance is simple and convenient, and the time is short.
