RU1801545C - Device for discharge of surface layer of water from settler - Google Patents

Abstract

Usage: collecting the surface layer of water in the sump. SUMMARY OF THE INVENTION: the device comprises a vertical pipe with a spillway in the upper part and connected in the lower part with a horizontal outlet pipe. An additional water inlet is installed craxially outside the vertical pipe below the overflow window. The invention provides a reduction in the content of fine particles in the drain due to the removal of the pull-in lower contaminated stream by an additional water inlet, 1 sludge.

FIELD OF THE INVENTION This invention relates to a technique for purifying recycled process water and can be used on horizontal settling tanks.

The aim of the invention is to increase the efficiency of surface water intake by improving the quality of clarification of water discharged from the sump.

The drawing shows the proposed device, General view.

The device consists of a vertical pipe 1 with a drainage window 2 in the upper part and connected in the lower part with a horizontal outlet pipe 3, an additional water inlet 4 installed in the upper part of the vertical pipe 1 and having an inclined bottom with an opening 5 in the lower part connected to separate vertical 6 and horizontal 7 branch pipes. At the end of the horizontal branch pipe 7, a control flap 8 is installed.

The device operates as follows.

The upper layer of clarified water is discharged from the sump into a vertical pipe 1 through a drain window 2 and then discharged outside the sump through a horizontal drain pipe 3. By increasing the flow rate in the spillway, the boundary of the contaminated flow rises. The pull-down bottom contaminated stream, not income to the drain window 2, enters the inlet 4 with an inclined bottom and through the hole 5 in the lower part, through separate vertical b and horizontal 7 outlet pipes, is discharged outside the sump into the sump-collector or fed back into the tailings discharge device to the sump. The discharge rate of the contaminated water layer is controlled by a shutter 8.
