Design of Decanter System Floating Tank Lifting Type

Abstract:

A new unpowered decanter system was designed to lift the decanting sink only by the dynamic provided by liquid level difference. The system arranged the float tank pools symmetrically in both ends of the decanting sink. The system was run by the difference of liquid level between float tank pool and reaction pool. When the level difference got small, the float tank would rise and hence lift up the decanting sink in the reaction pool to up above the liquid level; when the level difference got large, the float tank no longer received the buoyance so the decanting sink would float in the reaction pool and decant. The testing results of the experiment device showed that by means of difference of liquid level to lift the decanting sink was feasible. The new system is simple in structure, so that the construction and maintenance cost is not high. It also does not consume electricity. It provides a new decanter model.
