The screw press sludge dewatering machine

The #screwpress #sludgedewatering machine.

The #sludge squeezing and #dewatering is realized through the strong squeezing force generated by the change of screw diameter and pitch, and the small gap between the sliding rings and the fixed rings. It is a new type of solid

liquid #separation equipment. Can be widely used in municipal #sewage, food &

beverage, #slaughterhouses and breeding, printing and# dyeing, #petrochemical, #papermaking, leather, #pharmaceutical and other industries.

The unique dewatering principle makes the equipment suitable for high and low concentration #sludge (from 2000mg / L), creating a precedent for direct #dehydration of low concentration sludge. The innovative structure design makes the equipment suitable for all kinds of sludge with high and low viscosity, especially #oily sludge, which can be called the best dewatering tool for oily sludge!

Through #flocculation experiments, the matching #flocculent type and dosing ratio were determined. If two flocculants are needed for effective flocculation, it is recommended to choose two flocculation mixing tanks. The sludge tank should be equipped with a stirring device. Before and during the operation of the #dehydrator, the sludge must be continuously stirred to ensure the relative stability of the sludge concentration.

Before running the #volutedehydrator, the flocculent solution should be infused with the infusion device. Among them, the normal dilution of #polymer flocculent is 500-1000 times. The sludge is passed through the sludge conveying pump, the matured flocculent is fed into the flocculation mixing tank at the same time by the dosing pump, and is fully mixed by a mixer to form flocs, and the concentrate is #thickened by gravity. Drained out of the filter in the #thickening section. The filtrate in the concentration section has a low solid content and is directly returned to the original pond. The concentrated sludge is advanced forward along the spiral axis, and is fully #dehydrated in the dewatering section under the effect of various combined forces. The filtrate in the dewatering section has a high solid content and can be returned to the sludge tank. The dehydrated mud cake is discharged from the mud cake discharge port, and then sent to the mud truck through a shaftless screw conveyor or directly discharged for reuse.
