摘要:
A nozzle is provided for a header conduit. The nozzle includes an inlet that is resistant to clogs caused by flat materials covering the inlet. The inlet generally includes multiple pathways to an elongated passageway through which waste liquid and sludge (“waste”) are guided and enter the header conduit. In one embodiment, the elongated passageway is oriented to guide the waste along a path that is tangential to at least the inner surface of the header conduit which such incoming waste first contacts. When the conduit has an inner surface of circular cross-section, the passageway may optionally be elongated enough that the incoming waste enters the header conduit along a path tangential to the circular surface. To better assure axial flow of the waste in the conduit to an outlet, in one embodiment the passageway provides both the tangential flow and is at an acute angle to the longitudinal axis of the conduit. The incoming waste is thereby provided with an axial component. In this manner, the passageway assures that the energy and momentum of the incoming waste is helical in direction. The waste previously admitted into the header conduit is urged by the newly entering waste to continue to flow helically in the conduit. The passageways are provided at spaced intervals along the length of the conduit to collect sludge from a wide area of the bottom of the basin. Because of the tangential orientation of each of the passageways and the resulting initial tangential flow of the incoming waste, the waste incoming from each of those multiple passageways reinforces the existing helical flow of waste in the conduit.
