More Information
Summary:The invention discloses an ecological dredging jet pump, which comprises a jet water inlet pipe, a high-pressure distribution cavity and a silt outlet pipe which are connected in turn. Jet water is jetted into the outlet pipe through a primary jet spout and a secondary jet spout in the high-pressure distribution cavity, wherein the primary jet spout directly jets the jet water into the outlet pipe; and the secondary jet spout introduces the jet water into the outlet pipe through a streamline inlet. The ecological dredging jet pump utilizes the hydrodynamics Coanda effect to realize high speed flow, can avoid secondary pollution caused by using rotating components, and can be widely applied to ecological dredging and environment-friendly dredging of river courses, lakes and the like, and absorption of coal dust on the mine bottom of a coal mine.
