The thickener with a peripheral drive consists of a rake frame, trough frame, central support, current collection device, drive unit, etc. The drive unit transmits dynamic force from the electric motor to the frame, on which the rake hangs. Under the influence of this force, the frame rotates evenly around the center of the tank, and the rake collects the thickened product into the discharge hole in the center of the tank.
Meanwhile, the clarified overflow water flows along the circumference of the tank and is released through the ring-shaped drain trough.
With the help of the electric control system, programmed by the PLC, an alarm signal is triggered when the concentration of materials increases. It also performs hydraulic automatic lifting of the rake and sectional lifting of the rake, ensuring the normal operation of the equipment.
