Screw Press Environmental Protection Equipment
Application Scope
The screw press is widely used for sludge dewatering in industries such as municipal wastewater, food and beverage, slaughter and breed aquatics, printing and dyeing, papermaking, leather and pharmacy.
Mechanism
The separation unit of screw press is inter-stacked by the fixed
ring and the moving ring with a small gap between which the screw
shaft runs through. When the screw shaft rotates, the moving ring
is driven to be in circular motion. Water from the mud pie after
flocculation will be filtered out from the gap between and with the
moving ring in circulation, stoppage is prevented. Gap between the
fixed ring and the moving becomes small little by little along the
outward direction of the filter cake from the concentration area to
the dewatering area. And forced dewatering is made under the
backpressure formed on the backpressure plate at the mud outlet.
The Sludge delivery pump conveys sludge to the mud inlet. The
flocculating agent is measured and sent to the flocculation mixing
tank. There, sludge and flocculating agent are stirred, mixed and
flocculated fully into larger flocs in the blenders and then enter
the volute separation unit from the volute sludge inlet. In the
separation unit, flocs on the one hand concentrate under the
gravity and on the other hand move towards the dewatering area with
the spiraling effect. The gap gets narrow and the forcing watering
is furthered under the influence of the backpressure plate and the
filter cake is discharged from the sludge outlet.
