Product Structure

● The main part of the dehydrator is a filter device that a screw runs through the stacked fixed rings and moving ring.

● The small gaps between fixed rings and moving ring can filter the sludge, and the lumen between screw and rings is filled with polymer grains. The moving ring transfers the sludge to the end of the machine with pressure and extrudes sludge cakes.

● The running of the screw drives the moving ring to clean the gaps and avoid jam.

Flow Chart

● The sludge in the sludge sump is carried to the measuring tank by sludge pump.And the sludge inlet volume can be controlled by adjusting the liquid level tube.

● Sludge and flocculant will form alum floc in the disposal tank after agitator mixing, the ideal diameter of alum floc is about 5mm.

● After gravity thickening in the thickening part, large amount of filtrate will discharge from the gaps between rings.

● The thickened sludge is carried forward by the screw and dehydrated sufficiently under the pressure of the back pressure plate.

● The dehydrated mud cake is discharged from the gaps between back pressure plates and screw body. The treating capacity of sludge and water content’s rate of mud cake can be controlled by adjusting the running speed of screw and gaps between back pressure plates.
