ABSTRACT:
A rotary self-cleaning strainer comprises a circular cylindrical walled PVC pipe on which a circular cylindrical filter screen assembly is journaled for rotation. The PVC pipe has an intake that is surrounded by the filter screen assembly and a discharge that is connected to a pump. When the strainer is placed in a body of water that is to be pumped, water is drawn through the screen that forms the sidewall of the filter screen assembly and enters the intake of the PVC pipe. The filtered water is conducted through the PVC pipe and to the pump. A nozzle structure disposed within the filter screen assembly is supplied with water from a separate supply line connected to the strainer. The water is forcefully emitted against the screen to both rotate the screen assembly and dislodge adhering debris from the exterior of the screen. The strainer also has a lip type seal and a series of wheels which seal and journal one axial end of the filter screen assembly to and on the PVC pipe. The other axial end is journaled and sealed by a series of circular annular discs around a bushing on a pipe that passes coaxially through the PVC pipe and into which the nozzle structure is tapped. The intake is a series of holes of progressively increasing size in the direction away from the discharge.
