ROTATING FILTER Russian patent published in 2002 - IPC

FIELD: liquid filtration. SUBSTANCE: rotating filter includes at least two neighboring circular filtering discs, each having many filter members and secured on shaft for rotation round axis perpendicular to central plane of filtering discs. Discharging trough runs to gap between neighboring filtering discs for receiving and discharge of solid phase precipitated and removed from facing filtering means of filter members. Axial interval between the first section of trough upper edges located radially inside sections located radially to internal edges of facing means of neighboring filtering discs is not less than axial interval between sections of internal edges, and axial interval between the second section of upper edges located radially from outside of sections located radially to internal edges is not larger than axial interval between sections of internal edges of facing filtering means. EFFECT: higher efficiency of filtering. 7 cl, 13 dwg
