PLATED SELF-CLEANING FILTER Russian patent published in 2006 - IPC B01D29/64 

FIELD: construction of self-cleaning filters adapted for cleaning of liquids from mechanical contaminants.

SUBSTANCE: plated filter comprises vertical cylindrical casing equipped with connection pipes for introducing and discharging of medium, discharge device for discharging of sedimentation, cylindrical filtering member located within casing, and piston disposed within filtering member and fixed on rod of hydraulic cylinder positioned on casing cover. Cylindrical filtering member consists of radial metal plates fixed on inner circumference of band rings. Metal plates have projections. Piston located within filtering member is made in the form of disk with metal plates formed as equilateral trapeziums fixed on outer circumference of disk with their smaller bases. Ends of plates are positioned between plates of filtering members and project beyond outer diameter of filtering member.

EFFECT: continuous operation of apparatus due to effective cleaning of filtering member from mechanical contaminants and mechanized discharge of sedimentation.
