Liquid filter for filtering e.g. water for localized irrigation in agriculture, has outer cylinder with lower base through which water to be filtered passes tangentially, using centrifugal force, to separate high density particles

摘要

This invention refers to a filtering system for water and other liquids, which includes different filtering stages in the same element, with its cleaning being done automatically by a new procedure. The filtering system is comprised of a cylindrical outer casing with the pipe of the water to be filtered penetrating tangentially through its base, using centrifugal force in the first filtering stage to separate the particles with greater density. Then the liquid takes a helicoidal path and passes through different filtering devices, such as mesh, rings, etc., with the filtered and, therefore, clean water finally being collected in an appropriately perforated central pipe that comes out of the filter through the centre of its lower base. The system is used for the cleaning of liquids, basically water, in agriculture for localised irrigation, in industry, environment, etc.
