    Abstract: A cylindrical plastic pipe is used as the sidewall of the rotary portion of the strainer. Apertures are drilled radially through the pipe, and one or more screen assemblies are circumferentially wrapped around the outside of and removably fastened to the pipe to cover the apertures. The central core of the strainer contains both supply and suction pipes. The supply pipe feeds cleaning and drive nozzles that are aimed at the pipe apertures. The cleaning nozzles are aimed radially for cleaning certain apertures. The drive nozzles are aimed tangentially toward a circumferential succession of other apertures near the bottom of the pipe to drive the rotary portion. In one embodiment the drive nozzles can rotate the rotary portion in either direction.

    Abstract: A system for limiting the size of particulate matter entering a septic tank pump contains a strainer that has a straining screen through which the pump draws liquid from the septic tank. A nozzle receives some of the effluent being pumped by the pump and is aimed toward the screen for directing effluent toward the screen to dislodge particulate matter from an area of the screen while the pump draws liquid through the screen. The screen and nozzle are arranged for relative movement so that the area of the screen being acted on by the effluent from the nozzle changes as the pump operates. Various embodiments are disclosed.

    Abstract: A rotary self-cleaning strainer comprises a circular cylindrical walled pipe on which a circular cylindrical filter screen assembly is journaled for rotation. The 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 pipe. The filtered water is conducted through the PVC pipe and to the pump. Two sets of nozzles disposed within the filter screen assembly are supplied with return water through a supply line tapped into the pump outlet. The water is forcefully emitted against the screen to both rotate the screen assembly and dislodge adhering debris from the exterior of the screen. Each set of nozzles is 180 degrees from the other so that each acts upon a limited zone of the screen. The use of two nozzle sets enables the strainer to be effective in certain existing systems without having to increase the water pressure to be strained beyond the prevailing system pressure.

    Abstract: A strainer for immersion in liquid, especially shallow water, to prevent debris from entering a pump connected by a suction pipe to the interior of the strainer. The strainer has a cylindrical housing that is closed at the bottom and covered by a circular screen at the top. As the pump sucks water, the screen prevents debris from being sucked into the strainer interior along with the water. Debris drawn against the screen's exterior is dislodged by a rotating spray arm that contains nozzles and is disposed within the strainer interior to spray water against the screen. The water is fed under pressure to the spray arm through a separate supply line tapped into the pump's outlet. The spray arm nozzles are aimed to direct water generally upward through the screen to dislodge the debris and to cause the spray arm to rotate. Hence, as the spray arm spins, the water washes substantially the full face of the screen.

    Abstract: A novel all-wheel journaling of the rotary portion of a rotary self-cleaning strainer on a stationary central core. Respective sets of circumferentially spaced wheels are provided on respective end closures of the rotary portion that close opposite axial ends of a strainer screen to the central core. A first set of wheels on one end closure rides on a wear sleeve around the suction pipe of the stationary core, and a second set on the other end closure rides on a ring disposed around the supply pipe of the stationary core. Two additional rings sandwich the ring on the supply pipe to axially capture the second set of wheels and thereby axially capture the rotary portion on the central core. The rotary portion has a frame, including the end closures, for supporting the screen. Novel tie rod structures extend between the end closures.

    Abstract: A strainer that is used in association with a motor-driven pump that sucks water out of outdoor pits, reservoirs, streams, ponds, and the like, usually for irrigation or watering purposes. The strainer has a cylindrical screen disposed on a spool-like body for rotation substantially about its own axis. Nozzles that are disposed interiorly of the screen spray water outwardly through the screen to both rotate the screen and to dislodge any debris that may have accumulated on it due to the pump suction force. The screen is a plastic that has a specific gravity of approximately one and it is guided for rotation by the margins of circular discs that form the axial ends of the spool-like body.

    Abstract: A novel bearing-seal for the upper journal of a rotary self-cleaning strainer allows an existing strainer whose upper journal has become too loose to be reconstructed without the necessity of replacing the suction pipe, even though the suction pipe has been grooved by a set of circumferentially spaced wheels previously used for the upper journal. The bearing-seal can also be used in a new strainer instead of such a set of wheels. Where sealing is also required, the inventive bearing-seal has a sealing disc for replacing a previously used curved lip seal. The inventive upper bearing-seal significantly reduces rotational friction, enabling the strainer to be operated with significantly increased power efficiency, offering the potential for effective usage with lower pressure suction pumps.

    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.
