Product Introduction:

The stacked screw sludge dewatering machine can be widely used in municipal sewage treatment projects as well as water treatment systems in industries such as petrochemicals, light industry, chemical fibers, papermaking, pharmaceuticals, and leather. The actual operation has proven that the stacked screw sludge dewatering machine can create considerable economic and social benefits for customers.

working principle:

1. Concentration: When the spiral drive shaft rotates, the multiple solid and active laminations located on the outer periphery of the drive shaft move relative to each other. Under the action of gravity, water is filtered out from the gaps between the relative moving laminations, achieving rapid concentration.

2. Dehydration: The concentrated sludge moves forward continuously with the rotation of the screw shaft; Along the direction of the mud cake outlet, the pitch of the spiral shaft gradually decreases, the gap between rings also gradually decreases, and the volume of the spiral cavity continues to shrink; Under the action of the back pressure plate at the outlet, the internal pressure gradually increases. With the continuous operation of the spiral drive shaft, the water in the sludge is squeezed and discharged, and the solid content of the filter cake continues to increase, ultimately achieving continuous dewatering of the sludge.

3. Self cleaning: The rotation of the spiral shaft drives the moving ring to continuously rotate, and the equipment relies on the movement between the fixed ring and the moving ring to achieve a continuous self-cleaning process, thus cleverly avoiding the common problem of blockage in traditional dehydrators.
