PURPOSE:To enable to use the supernatant water in sucked matters again for suction work by providing a supernatant-water automatic discharge device with an inlet port with an airtight valve, an outlet port with an airtight valve, and a pressure-reduction releasing mechanism for continuously discharging the supernatant water to the outside of the suction mechanism. CONSTITUTION:This device is constructed of a suction mechanism at least consisting of a suction device, a silencer arranged on a route in the downstream of the air flow direction A of this suction device, and a reservoir tank 4 arranged in the upper stream of the air flow direction of this suction device, and a supernatant-water automatic discharge device 6 connected to the tank 4 via a supernatant-water passage port 5 to be airtight and liquid-tight. This device 6 is equipped with an inlet port 8 with an airtight valve 7, a discharge port 10 with an airtight valve 9, and a pressure-reduction releasing mechanism 13 consisting of a releasing valve 11 and a float 12. This construction permits to discharge the supernatant water in sucked matters continuously to the outside of the suction mechanism without stopping the suction mechanism for discharging the supernatant water, and use this supernatant water again to make suction work for accumulating only solid components of the sucked matters in the reservoir tank. |
