Novel Design Sludge Dehydrator Screw Filter Press Dewatering
Machine
Product Overview Of Sludge Dewatering Machine
Screw sludge dewatering machine, originating from the advanced
technology of foreign countries, is introduced into China to
realize localization. The automatic renewal filtration technology
is cleverly used in the sludge dewatering machine to replace the
traditional filter screen filtration. The self -renewal filtration
technology ensures that dewatering machine can separate sludge from
sewage water stably. It is a new solid-liquid separation equipment
to extrude and dehydrate the sludge through the strong extrusion
pressure caused by the change of screw diameter and pitch, as well
as the small gap between the floating ring and the fixed ring.

Structure & Advantages
The core part of the screw sludge dewatering machine is one or
several groups of filter units composed of a screw drive shaft,
multiple fixed laminations and multiple floating laminations. Each
filter unit is divided into two parts: concentration section and
dehydration section. From the sewage inlet of the concentration
section to the mud cake outlet of the dewatering section, the pitch
of the screw shaft gradually decreases, and the gap between the
fixed ring and the moving ring gradually changes. small. There is a
back pressure plate at the sludge outlet to adjust the pressure in
the spiral cavity. The spiral sludge dewatering machine completes
the thickening and squeezing and dewatering of the sludge in one
cylinder, replacing the traditional filter cloth and centrifugal
filtration method with a unique and subtle filter body mode.
Working Process
1. Thickening: When the screw drive shaft rotates, the multiple
solid and active laminations arranged on the periphery of the drive
shaft move relative to each other. Under the action of gravity,
water is filtered out of the relatively moving lamination gap to
achieve rapid concentration.
2. Dewatering: The concentrated sludge moves forward with the
rotation of the screw shaft; along the direction of the mud cake
outlet, the pitch of the screw shaft gradually decreases, and the
gap between the rings gradually decreases, and the volume of the
spiral cavity Constantly shrinking; under the action of the back
pressure plate at the outlet, the internal pressure gradually
increases. Under the continuous continuous operation of the screw
drive shaft, the water in the sludge is squeezed and discharged,
and the solid content of the filter cake continues to increase,
finally achieving sludge Continuous dehydration.
3. Self-cleaning: The rotation of the screw shaft pushes the moving
ring to continuously rotate. The equipment relies on the movement
between the fixed ring and the moving ring to achieve a continuous
self-cleaning process, thereby cleverly avoiding the common
blocking problem of traditional dehydrators.
