Our
decanter can be used to thicken the sludge, dewater the sludge
or thicken-dewater the sludge. The whole sludge dewatering
system has five parts:

Electric
Control System of Complete Set |
We configure different electric control system for different
customer needs:
| 1) |
Simple
Type: Able to control automatically during operation |
| 2) |
General
Type: Have PLC control |
| 3) |
Intelligent
Type: PLC+PC Control, have data sampling and output |
Main Characters of Our Sludge Dewatering Centrifuge
with Bigger Length/Diameter Ratio
1) |
Length/Diameter
Ratio L/D≥4.3.High rotating speed and low differential
speed system is adopted. Bigger length to diameter
ratio increases the resident time of the mixture inside
the bowl so that the time for liquid clarifying and
solid dewatering is prolonged. High rotation speed
generates great centrifugal force. Small differential
speed reduces the stirring of screw to the solid.
With the increased residence time, good efficiency
for dewatering the sludge and clarifying the centrate
is achieved. Comparing with typical decanter centrifuges,
drier solid cake and clearer centrate is produced
by this kind of machine. |
2) |
Big
torque hydraulic backdrive is adopted. This provides
bigger drive torque. (If the size is the same, the
drive torque of hydraulic backdrive is 2 to 4 times
of that of mechanical gearbox.) |
3) |
Hydraulic
differential speed system is adopted. The output torque
is greater （≥16000Nm）. The differential speed changes
with the load. The differential speed is adjusted
automatically through feedback. The discharge power
is automatically compensated. In this way, the solid
inside the bowl is compacted under the centrifugal
force. Moreover, The solid is extruded between the
screw blades in the conical section of the bowl. In
this way, the discharged solid maintains a invariable
dryness and the solid is more dryer. When solid is
discharged out of the bowl , the differential speed
automatically comes back to its original value. The
solid bowl is almost free of clogging. If the throughput
is the same, 30% chemical and electricity consumption
can be saved by using our decanter. The noise is lower
than 84dB. |
4) |
Wide
adjustment range of starting differential speed: the
differential speed is adjusted within the range from
0 to 20 rpm. |
5) |
Super
hard abrasive-resistant material W2C-65% is spay welded
on solid discharge port, feed port and conveyor blade.
The thickness if 2~3mm. Comparing to tiles, it has
better duration and needs no replacement. This prolongs
the operation life. |
