WAYS OF CENTRIFUGAL FILTRATION IMPROVEMENT Russian patent published in 2008 - IPC B04B3/00 

FIELD: technological processes.

SUBSTANCE: invention is referred to methods of increasing separation efficiency of solid and liquid phases during the centrifugal filtration performed in the tank (1) for centrifugal filtration. These methods lie in increase of overfall of pressure through a filtering deposit (6) with use of an exposure, such as gas introduction through an inlet pipe (9) for compressed air to augment pressure of gas in the filtering chamber, and/or the application of vacuum to an outer side of the filtering chamber. The external unit of increase in overfall of pressure is designed to augment speed of water removal during the drainage period at a centrifugal filtration and, hence, to reduce amount of residual water.

EFFECT: lowering of damp of the filtered deposit.
