Abstract:
A pumping station for pumping a fluid that contains particulate matter, comprising:a collecting container including a floor pan having a sloped floor part that is arranged to slope downward from a higher location to a lower location;first pump having a first suction inlet in communication with said collecting container at said lower location and having a discharge outlet;an inlet junction adapted to receive a flow of the liquid containing the particulate matter;a first branch line adapted to have the fluid flow therethrough to said collecting container, and having a first inlet end connected to said inlet junction, a first outlet communicating into said collecting container at said higher location, and a downward slope from said first inlet end to said first outlet;a second branch line adapted to have the particulate matter move therethrough, and having a second inlet end connected to said inlet junction, a second outlet communicating into said collecting container above said first outlet, and an upward slope from said second inlet end to said second outlet; anda flushing fluid conduit that is adapted to have a recirculated partial flow of the fluid conveyed therethrough, and that communicates into said collecting container along said sloped floor part at location adjacent and downstream from said first outlet;wherein said second outlet of said second branch line and said first outlet of said first branch line are located and arranged relative to one another such that a particle flow of the particulate matter falling from said second outlet into said collecting container falls onto a fluid flow of the fluid flowing from said first outlet into said collecting container.
