Abstract:
A fluid filter apparatus comprising: fluid receiving tank means having opposed side walls and including a first tank section to receive a dirty fluid to be filtered from a dirty fluid source and a successive second tank section to receive remaining clean fluid after it has been filtered; longitudinally extending porous filtering means having opposed side edges moveable in a plane between said first and second tank sections, said filtering means being adapted to separate out particulate matter from said dirty fluid as it is passed from said first tank section to said successive second tank section; fluid recirculating means to recirculate a portion of said clean fluid in said second tank section; to said first tank section, fluid dispensing sealing means connected to said fluid recirculating means in removed, spaced alignment with at least said opposed side edges of said porous filtering means so as to provide and direct clean fluid extended curtains toward and along said opposed side edges of said porous filtering means, said clean fluid extended curtains restricting dirty fluid introduced into said first tank section from by-passing said porous filtering means by flowing around said opposed side edges of said porous filtering means thus insuring passage of said dirty fluid through said longitudinally extending porous filtering means; and, power means associated with said moveable filtering means and said fluid recirculating means to appropriately energize same in accordance with a preselected adjustable program.
