Abstract

A pre-filter layer of sand is formed around a filter tube comprising a spring and after filtration is completed, the sand is dried with air and shaken off by vibrations. A method for filtering liquids under pressure in order to remove solids comprises forming a pre-filter layer of sand around filter tubes formed by springs with small gaps between their coils, so that a tubular sheath of sand is formed the filter tube. The liquid to be filtered is passed through the filter under pressure, then once filtration is complete, air is introduced into the tube to dry out the sand and vibrations are used to remove the dried sand. An Independent claim is also included for the filter device.
