Control apparatus for setting the speed of rotation of rotary sprinklers in trickling filters and sewage treatment plants

摘要

The invention relates to a control apparatus for setting the speed of rotation of a rotary sprinkler, driven by hydraulic reaction, in trickling filters of sewage treatment plants, the reaction being produced by the waste water exiting from orifices in the distributor tube. On at least one distributor tube (6), in the vicinity of at least some of the outlet orifices (7), there is arranged a baffle plate (8) to be able to pivot or fold in two positions in bearings (10) or hinges and which guides the exiting jet (22) either in the direction (9) of rotation or opposite to the direction (9) of rotation. <IMAGE>
