ABSTRACT:
A high efficiency, self-cleaning system for separating solid materials from liquids. The system includes a primary housing having at least one inlet and a plurality of cylindrical filter cartridges therein which are directly adjacent to and in close proximity with each other. The lower end of each cartridge is positioned on a spring-biased bearing member, with the upper end having an opening therein. Positioned within the opening and connected to each cartridge is a tubular shaft attached to a pulley-type motor drive system. The drive system is used to rotate the cartridges in a selected direction. In operation, fluids to be filtered enter the housing and come in direct contact with the rotating cartridges. Rotation of the multiple cartridges and close proximity of the cartridges to each other creates fluid turbulence within the housing. This turbulence scrubs collected solids from the cartridges and promotes fluid flow into the cartridges. Fluids collected within the cartridges pass into the tubular shafts and out of the system. As a result, the fluids are effectively filtered in a rapid and efficient manner while minimizing system down-time.
