the inlet openings of the others are located either completely below or above the water level. The number of hydraulic lines with water flowing through them will differ, depending on the water level in the upper backwater chamber.
The present invention is directed to an apparatus for guiding portions of backwater produced or stored at different levels of a machine. The apparatus includes an upper backwater chamber arranged to receive first backwater, a lower backwater chamber arranged below the upper backwater chamber and to receive at least a portion of the first backwater from the upper backwater chamber. A plurality of hydraulic lines are arranged to couple the upper backwater chamber to the lower backwater chamber, and inlet openings of the plurality of hydraulic lines are arranged inside thefirst backwater from the upper backwater chamber to a lower backwater chamber through inlet openings to a plurality of hydraulic lines. The inlet openings are arranged at different geodetic heights relative to one another.
According to a feature of the present invention, a level of the first backwater in the upper backwater chamber is such that one of the inlet openings can be partially filled with the first backwater.
The process can further include guiding the first backwater into the lower backwater chamber at a level below a second backwater level contained in the lower backwater chamber.
The first backwater may be guided through concentrically arranged hydraulic tubes.
In accordance with still yet another feature of the instant invention, a first backwater level can controlled by a weir and an overflow drain.
