Abstract
An adjustable-flow floating weir assembly is provided for regulating the flow of liquid out of a basin which receives a constant or variable flow of liquid. The weir assembly communicates with the exterior of the basin and has notches through which liquid from the basin flows into the weir assembly. The buoyancy of the weir assembly can be changed to correspondingly vary the vertical position of the weir assembly relative to the liquid level in the basin to thereby regulate the flow of liquid through the notches into the weir assembly and to the exterior of the basin.
Claims9
An adjustable-flow floating weir assembly in a liquid-containing basin for regulating the flow of liquid out of said basin, comprising:
- a receptacle including a peripheral wall and a bottom, said wall having a peripheral portion extending upwardly from said bottom and defining at its upper edge a plurality of peripherally spaced notches and a lower peripheral non-porous skirt portion extending below said bottom to a lowermost edge, said lower skirt portion and bottom defining a chamber, said bottom defining an opening, conduit means communicating with said opening and connecting said receptacle to the exterior of said basin, passage means for air to flow under pressure to and from a region within the chamber adjacent the underside of said receptacle bottom above the lowermost edge of said skirt and means for controlling the flow of said air whereby the vertical position of said weir assembly can be varied to regulate the liquid flow through said notches to the exterior of said basin.
An adjustable-flow floating weir assembly in a liquid-containing basin for regulating the flow of liquid out of said basin, comprising:
- a receptacle including a bottom and a peripheral wall having a peripheral portion extending upwardly from said bottom and defining notches at its upper edge to limit the flow of liquid through said weir assembly, depending peripheral non-porous baffle means sealed to said bottom and extending below said bottom to a lowermost edge defining therewith a chamber, said bottom defining an opening, conduit means communicating with said opening and connecting said receptacle to the exterior of said basin, passage means for air to flow under pressure to and from a region within the chamber adjacent the underside of said receptacle bottom above the lowermost edge of said baffle means and means for controlling the flow of said air whereby the vertical position of said weir assembly can be varied to regulate the liquid flow through said notches to the exterior of said basin.
