FIELD: technological processes. ^ SUBSTANCE: invention concerns instrumentation of radial-flow settlement tanks for sewage treatment. Device includes a cage in the form of a bridge with its own drive, and collector and rake unit in the form of a hub with a rake connected to it kinematically, both collector and rake unit connected to the cage kinematically. The hub is rotated by an independent drive mounted on the cage. The collector is attached to outer rake end, and at least a part of rake, if projected to radial-flow settlement tank bottom, is tilted against the segment connecting hub axis and outer rake end. The collector can consist of two parts connected by joints. ^ EFFECT: simplified construction and increased reliability of bottom cleaning device for radial-flow settlement tank. ^ 2 cl, 2 dwg |
