Abstract
A vibratory screen separator system having a moving manifold, angled feed nozzles, and angled spray nozzles. The spray nozzles and the feed nozzles are attached to the bottom of the manifold, and the manifold moves back and forth over the screen. The feed nozzles evenly distribute the material to be separated across the screen. The spray nozzles clean the screen before each pass by the feed nozzles.
Claims26
A separator comprising
- a vibratory screen;
- a feeder positioned above said vibratory screen, said feeder including a guide way, a manifold movably mounted on said guide way and having a plurality of feed nozzles directed toward said screen, and a feeder drive coupled to said manifold to move said manifold along said guide way.
A separator comprising
- a vibratory screen;
- a feeder positioned above said vibratory screen, said feeder including a guide way, a manifold movably mounted on said guide way and having a plurality of feed nozzles directed toward said screen, a plurality of spray nozzles directed toward said screen and a feeder drive coupled to said manifold to move said manifold along said guide way.
A method for screening liquid, comprising the steps of
- vibrating a screen;
- distributing influent with back and forth movement onto the vibrating screen;
- spraying clear water with the same back and forth movement onto the vibrating screen adjacent the influent such that both the influent and the clear water are presented to the same areas of the screen seriatim.
A separator comprising
- a vibratory screen including a taut screen cloth, a discharge at one side of said screen cloth, resilient mounting supporting said screen cloth and a vibratory drive coupled to said screen cloth;
- a feeder positioned above said vibratory screen, said feeder including a guide way, a manifold movably mounted on said guide way and having a plurality of feed nozzles, and a feeder drive coupled to said manifold to move said manifold along said guide way, said feed nozzles being directed toward said screen cloth with said manifold at any position along said guide way and each said feed nozzle having a substantially rectangular orifice extending parallel to and inclined toward said discharge.
A separator comprising
- a vibratory screen including a taut screen cloth, a discharge at one side of said screen cloth, resilient mounting supporting said screen cloth and a vibratory drive coupled to said screen cloth;
- and
- a feeder positioned above said vibratory screen, said feeder including a guide way, a manifold movably mounted on said guide way and having a plurality of feed nozzles directed toward said screen, a plurality of spray nozzles directed toward said screen and a feeder drive coupled to said manifold to move said manifold along said guide way, said feed nozzles and said spray nozzles being directed toward said screen cloth and inclined toward said discharge with said manifold at any position along said guide way.
A separator comprising:
- a vibratory screen having a discharge;
- a feeder positioned above said vibratory screen, said feeder including a guide way, and a manifold movably mounted on said guide way and having a plurality of feed nozzles directed toward said screen, a plurality of spray nozzles directed toward said screen and a feeder drive coupled to said manifold to move said manifold along said guide way, said feed nozzles and said spray nozzles being directed towards said screen cloth and inclined toward said discharge with said manifold at any position along said guide way.
