ABSTRACT:
This invention provides means to screen long, slender objects from a flowing fluid, and more particularly provides means to clear jammed objects therefrom. The screening means comprises a set of opposed, aligned, undulating surfaces, preferably formed as corrugated plates, located within a conduit, that can be moved apart to permit the removal of trapped debris. The plates are so mounted as to be transversely movable relative to the conduit, and are each movable relative to the adjacent plates so as to permit increasing the separation between adjacent plates when the plates are moved to outside of the conduit. The liquid screening means of this invention can usefully be included in a suction type dredging device, between the inlet nozzle and the pump.
