DISC FILTER SECTOR AND DISC FILTER Russian patent published in 2012 - IPC B01D33/21 B01D33/23 

FIELD: process engineering.

SUBSTANCE: invention relates to filtration. Proposed filter comprises adjacent triangular sectors forming disc-like fine structure, casing with, at least, one tubular part rotating about central axis and furnished with sectors secured thereto, vessel accommodating revolving disc, at least one feed channel, means to create negative pressure inside said sector, at least one discharge channel, means to withdraw solid substance accumulated on sector outer surface, and at least one exhaust solid substance discharge trunk. Every sector includes opposite side surfaces with holes, sides connected with side surfaces in radial direction, strap on sector outer edge, section on sector inner edge connected with casing, one, in fact, radial flow channel communicated with side surface holes and neck section. Sector comprises first and second side elements made from plastic and, at least, two, in fact, radial parallel flow channels. Side elements make separation wall between parallel flow channels extending continuously from sector strap to sector neck section to separate flow in adjacent parallel flow channels.

EFFECT: higher efficiency of filtration.
