CARRIER OF SLUDGE RAKE FOR RADIAL-FLOW SETTLEMENT TANK Russian patent published in 2008 - IPC B01D21/18 B62D21/00 

FIELD: technological processes.

SUBSTANCE: invention concerns sewage treatment equipment. Carrier of sludge rake for radial-flow settlement tank includes bridge 1, ring bearing 2 of the bridge, positioned in the centre of radial-flow settlement tank, and two-wheel driving truck 4 mounted on the tank edge, with serial wheel arrangement. Frame 6 of two-wheel driving truck 4 has one longitudinal beam 7 and two cross-beams 8 connected to it. Longitudinal beam 7 is rigidly fixed to bridge 1. Cross-beams 8 carry front and rear double-arm suspension levers 14 and 15, rotating around axes 12 and 13, with horizontal arms directed towards each other. Front wheel 18 and rear wheel 19 of two-wheel driving truck are mounted on horizontal arms of double-arm suspension levers 14 and 15, together with rotation drives 20. Vertical arms of double-arm suspension levers 14 and 15 are connected by joints to a rod 23 linking them. Each cross-beam 8 of the two-wheel driving truck can be flexibly attached to longitudinal beam 7 with possibility of rotation around vertical axis 9 and rotation restriction by rigid bolt joint 10 mounted in slots 11 of cross-beams 8, allowing cross-beam position adjustment against the ring bearing 2 of the bridge.

EFFECT: reduced sideslip force moment affecting sludge rake carrier and increased operational reliability.
