During the operation of the Screw sludge dewatering machine, the sludge in the sludge tank can effectively pass through the sludge transfer pump, and is transported to the metering tank during use, and the liquid in the metering tank is adjusted during operation. The position adjustment tube regulates the amount of mud, and the excess sludge is returned to the sludge tank through the return pipe.
The sludge and flocculant of the screw sludge dewatering machine are in the flocculation mixing tank, and are fully mixed by a mixer to form the silk flower during operation. The ideal diameter of the silk flower is about 5 mm. The silk flower is concentrated by gravity in the enrichment section, and a large amount of filtrate is discharged from the filter slit of the enrichment section.
The screw sludge dewatering machine continues to advance in the direction in which the concentrated sludge rotates in the direction in which the screw shaft rotates, and is sufficiently dehydrated under the action of the internal pressure formed by the back pressure plate. The dehydrated mud cake is discharged from the gap formed by the back pressure plate and the spiral body. The sludge treatment amount and the moisture content of the mud cake can be adjusted by adjusting the rotational speed of the screw shaft and the gap of the back pressure plate.
