Product Description



Working principle:
Thickening: When the shaft is driven by the screw, moving rings around the shaft move up and down relatively. Most water is pressed out from the thickening zone and fall down to the filtrate tank for gravity.
Dewatering: The thickened sludge moves forward continuously from the thickening zone towards the dewatering zone. With the pitch of the screw shaft thread getting narrower and narrower, the pressure in the filter chamber increases higher and higher. In addition to the pressure generated by the back-pressure plate, the sludge is greatly pressed and dryer sludge cakes produce.
Self-cleaning: The moving rings rotates continuously up and down under the pushing of the running screw shaft while the gaps between the fixed rings and moving rings are cleaned to prevent from clogging that happens frequently for traditional dewatering equipment.
Product feature:
Special pre-concentrating device, wide feed solids concentration: 2000mg/L-50000mg/L
The dewatering part of MSP (multi-plate screw press) consists of a thickening zone and a dewatering zone. In addition, a special pre-concentrating device is mounted inner the flocculation tank. Therefore, the wastewater with rather low solids content is not a problem to MSP. The applicable feed solids concentration can be as very wide as 2000mg/L-50000mg/L.
The sludge in the sludge storage tank is transported to the meter- ing tank through the sludge con- veying pump
The sludge is transported to the floccula- tion mixing tank by metering, and the remaining sludge is returned to the sludge storage tank by adjusting the water level
The polymer flocculant is in- jected, and the sludge reacts with the polymer flocculant to form flocculant, which is transported to the main body ofthe screw
The sludge is transported to the screw body, and the sludge is ex- truded and dehydrated by the strong extrusion pressure gener- ated by the change ofscrew di- ameter and pitch
The gap between the moving ring and the fixed ring of the de- hydration part Narrows, and the decement cake is dehydrated by the back pressure plate, and the mud cake is discharged
