 PolyRex double-deck preparation station
The upper tank is the preparation/maturing tank, the bottom tank is the storage tank for the prepared polymer solution. The powdery polymer is transported to the powder feeder by a vacuum conveyor
and mixed with water in the bottom mixer unit. The solution is than transferred to the upper tank (preparation/maturing tank) using the water pressure of the diluent water. Having matured, the solution
can be transferred to the bottom storage tank via the motor valve.
When using liquid polymers, the system switches to the Spectra eccentric screw pump.
The system is automatically controlled by a Siemens PLC S7.
PolyRex basically consists of the following components:
- vacuum conveyor and powder feeder to meter powdery polymers and an eccentric screw pump to
meter liquid polymers.
- water fitting with wetting cone and injector to produce an effective and homogeneous polymer solution
from powdery polymers (modified system when using liquid polymers)
- double-deck tank made of stainless steel for maturing and storing the polymer solution.
- motor valve to transfer the solution to the storage tank.
- agitator in the upper tank for a gentle mixing of the polymer solution
- control cabinet with S7 control for automatic control of the system.
