Abstract (en)
[origin: US5954484A] A sewage lifting station having at least two solid waste collection chambers for receiving pumped solid waste-contaminated sewage. The station has a collection tank for receiving pre-treated waste water flowing from the solid waste collection chambers via connection pipes. Each solid waste collection chamber is connected to a pump to empty the collection tank via one of the connection pipes and solid waste collection chambers to pump the current of sewage into a pressure pipeline. There is a closing device connected to each connection pipe to selectively close an exit orifice in the connection pipe and open a connection to an operating pump to drain the collection tank. A control device alternately closes and opens the exit orifices with the closing devices so that an exit orifice allocated to an operating pump is closed and an exit orifice allocated to a non-operating pump is simultaneously and automatically opened. The present invention ensures precise opening and closing of the exit orifices, thus ensuring efficient operation of the sewage lifting station.
