FIELD: construction.SUBSTANCE: device consists of supply channel 1 with cantilever 3, transit channel 2, and receiving well 4. Rotating filter element 8 with water-permeable plate 18 attached to horizontal rotation axis 11 is installed above well 4 on the side of transit channel 2. Element 8 consists of a set of two similar plates 9 and 10 attached to axis 11. Free end of plates 9 and 10 has slot 13. Horizontal plate 14 is attached with a plane to free ends of plates 9 and 10 and to the end of element 8. Flushing hole 15 with seal 16 is made in element 8 at attachment point to axis 11. Supporting plate 17 is located with an inclination towards transit channel 2 and attached to bottom edge of element 8. Transverse slot 28 for support position of supporting plate 17 is arranged at the bottom of transit channel 2. Grid 22 together with brier teeth 23 and 24 is fixed at the bottom of supply channel 1 with possibility of being turned on horizontal axis 21 and is restricted with a stop in the form of transverse vertical wall 27. Grid 22 is located above filter element 8 and has curved shape and faces with its concave side towards element 8. Slot 13 in plates 9 and 10 of element 8 is installed coaxially to bent end 25 of brier teeth 23 and 24 and the latter are restrictors of its vertical position.EFFECT: simplifying design of the device and improving its operation reliability and water treatment quality.5 cl, 6 dwg |
