WATER INTAKE PURIFYING FACILITY Russian patent published in 2014 - IPC E02B8/02 

FIELD: construction.

SUBSTANCE: water intake purifying facility includes the receiving settling chamber 1 and additional settling chamber 2 between the supply 3 and outlet 4 water lines. The receiving settling chamber 1 for collecting sediments is designed with the inclined bottom and is divided by vertical separating wall 5 into two sections 6 and 7, unified by the window 8. Window 8 is designed in the lower part of separating wall 5. Chamber 1 has a flushing opening 9 with the collector 10. The second section 7 of chamber for collecting sediments is provided with vertical T-shaped wall 14 with horizontal brim 15 at the end of the inclined bottom. Wall 14 is secured to the bottom of pit 16, 20. Visor 15 by one end is mounted to the side of separating wall 5, and by the other - to the side of additional settling chamber 2. Receiving settling chamber 1 is provided by width with horizontal training walls 11, installed by height relative to each other with offset respectively to the separating wall 5. Training walls 11 are fixed from side of the second section 7 of chamber 1. Additional settling chamber 2 is located between the vertical T-shaped wall 14, wall 17 and threshold 18 of discharge section of water line 4. Bottom of chamber 2 is designed with inclination towards the pit 20 with flushing hole 21 with collector 22. Separating wall 5 from the inner side in its upper part is provided with the curved visor 12 with the slotted opening 13. During the facility operation, water containing sediments enters into the receiving settling chamber 1, where slows and sediments are concentrated in the lower part of section 7, and partial possibly suspended sediments enter along the inclined bottom of chamber 2 and drawn into the pit 20 near the flushing hole 21 with collector 22.

EFFECT: efficiency of continuous purification of water from the bottom and suspended sediments is improved, possibility to control the hydraulic flow structure in the additional sedimentation chamber is provided.
