Abstract
This invention relates to apparatus for continuously discharging liquid from a container, such as a waste water tank having a discharge pipe with an inlet located adjacent the container floor and an outlet located outwardly of the container. The liquid flow is controlled by a control unit which operates as a function of the liquid level in the container. The discharge pipe has a riser section between its inlet and its outlet which extends upwardly to an apex section to define an overflow for the liquid. The riser section is adjustable in height which is controlled by control means that always maintains the overflow at a constant elevation below the liquid level in the container.

Apparatus for the continuous constant discharge of liquid from a container therefor having a discharge pipe with the inlet thereof located in the container and the outlet thereof located outside of the container and with the liquid flow therethrough being controlled by a control unit operating as a function of the liquid level in the container, the improvement in that said discharge pipe is generally U-shaped and both ends thereof are located in the vicinity of the floor of said container and has an ascending riser section between said inlet and said outlet with said riser section extending upwardly to an apex section at the base of the U-shaped discharge pipe to define an overflow for the liquid, and control means operatively connected to said discharge pipe to adjust and control the height of said riser section of the discharge pipe in response to fluctuations of the liquid level in said container to maintain said overflow for the liquid at a constant elevation below said liquid level in said container.
Apparatus for the continuous constant discharge of liquid from a container therefor having a discharge pipe with the inlet thereof located in the container and the outlet thereof located outside of the container and with the liquid flow therethrough being controlled by a control unit operating as a function of the liquid level in the container, the improvement in that the inlet of said discharge pipe is located in the vicinity of the floor of said container and has an ascending riser section between said inlet and said outlet with said riser section extending upwardly to an apex section outwardly of said container and into a receiving chamber which is separated from said container to define an overflow for the liquid which is located within said apex section, control means operatively connected to said discharge pipe to adjust and control the height of said riser section of the discharge pipe in response to fluctuations of the liquid level in said container to maintain said overflow for the liquid at a constant elevation below said liquid level in said container, and an impact surface is provided in said receiving chamber onto which the liquid falls with said impact surface having a curved contour corresponding to the path of movement of said overflow in said apex section.
