Abstract
A screen intake system has a body with an open end and a chamber. A flat screen is disposed at the open end of the body. To keep the screen clear of debris, an airburst system has pipes disposed in the chamber. The pipes dispose parallel to one another adjacent the flat screen, and each of the pipes has orifices in a side facing the flat screen. Directors are disposed along the backs of the pipes in a lattice, and each of the directors has a channel in which the pipe disposes. Compressed air released by valves from a tank dispersed from the pipe's orifices. Each of the directors directs the resulting water/airburst from the orifices toward the adjacent flat screen to clear it of debris.
Claims20
A debris cleaning apparatus for a screen, the apparatus comprising:
- a manifold in fluid communication with an inlet of the apparatus and defining at least two flow areas, a first of the flow areas in fluid communication between the inlet of the apparatus and a second of the flow areas, the first flow area being greater than the second flow area;
- a plurality of pipes disposed parallel to one another and in fluid communication with the manifold, each of the plurality of pipes comprising a proximal end and a distal end, wherein the proximal end is in fluid communication between the manifold and the distal end, each of the plurality of pipes having a first side adjacent the screen and having a second side opposite the first side, each of the plurality of pipes comprising a plurality of orifices for expelling fluid, the proximal end of at least one pipe of the plurality of pipes defining a third flow area and the distal end of the at least one pipe of the plurality of pipes defining a fourth flow area, wherein the third flow area is greater than the fourth flow area;
- and
- a plurality of directors disposed parallel to one another in a lattice, each director having at least one of the plurality of pipes affixed therein and having a channel in which at least a portion of at least one of the plurality of pipes disposes, each director directing fluid expelled from the orifices in at least one of the plurality of pipes toward the adjacent screen.
