Self-cleaning filters for water purification from mechanical impurities from the filter surface consisting of perforated semi-cylindrical ELEMENTS

摘要

A filter for purifying water taken from open water from mechanical impurities, comprising a cylindrical housing with disposed on the cylindrical surface on opposite sides of pipe for supplying polluted and nozzle withdrawal of purified water, mounted within the housing and provided with a tapping pockets with rectangular cross section inputs to suction debris perforated filter surface arranged circumferentially, whose axis has an eccentricity relative to the body axis in the opposite directed w water movement and pivoting flushing device with a pivot axis coaxial with the axis of the filter surface, and having a suction chamber to the inlet of rectangular section identical to the cross section of the entrance of the intake pocket filter surface, characterized in that the filter surface is made up of interconnected edges of the semi-cylindrical elements facing concavity facing upstream water as flushing device is arranged rotatably by 360 °.
