SEWAGE DRAINAGE SYSTEM OF MOVABLE TYPE SEWAGE SOURCE

摘要

PROBLEM TO BE SOLVED: To suck sewage, and to force-feed sewage to a remotely separate sewage main pipe by connecting drain pipes for a toilet tank in a plurality of simple toilets to one vacuum suction apparatus and successively opening and closing electromagnetic on-off valves for each drain pipe at fixed time intervals. ;SOLUTION: Drain inlets 6, 9 for toilet tanks 5 in a plurality of simple toilets 1 and the water storage tank 2a of a simple cooking facility 2 are connected to a main drain pipe 10 with a vacuum suction pump 13 and a pressure pump 14 through drain pipes 7 with electromagnetic on-off valves 8. Electricity is conducted successively through solenoids for each electromagnetic on-off valve 8 at fixed time intervals by a controller, one electromagnetic on-off valve 8 is opened for a fixed time, the vacuum suction pump 13 and the pressure pump 14 are driven, and sewage is discharged to a manhole 17 for a remotely separate sewage main pipe 16 through a discharge pipe 15. Level sensors are installed to each toilet tank 5 and the water storage tank 2a, and sewage and water are sucked and discharged preferentially from the tanks, in which water levels reach fixed values. Since sewage and water are not sucked simultaneously from each toilet tank 5 and the water storage tank 2a, the small-sized vacuum suction pump 13 may be used.;COPYRIGHT: (C)1997,JPO
