Continuous Flow, Variable Capacity Self-Compensating Floating Weir
Continuous Flow, Variable Capacity Self-Compensating Floating Weir
US Patent:
4405458, Sep 20, 1983
Filed:
Apr 29, 1980
Appl. No.:
6/144967
Inventors:
Leo A. McHugh - Pittsburgh PA
International Classification:
E02B 1504
US Classification:
2102423
Abstract:
The floating weir is a device for regulating or maintaining continuous flow from the surface level of a liquid body. As designed, the device provides a continuous, uninterrupted weir edge for controlling liquid flow. The device is particularly suited for skimming applications such as the removal or separation of surface debris, films, scum or secondary liquids of lesser density from a primary liquid body. The unit can be mounted as a fixed installation, such as a connection to a standpipe or, when mounted on a floating platform, as a mobile floating unit. The unit utilizes a float supported weir that is unattached to the apparatus, except for contact with an adjustable retainer, which sets the weir elevation and flow rate. The floating weir is mounted within a close fitting guide collar which guides weir movement and provides, in effect, a liquid seal between these members. The liquid seal also provides a lubricating film to insure free vertical weir movement.
