ABSTRACT:
The invention relates to a floating paddlewheel aerator for aerating water or clearing basins. The paddlewheel aerator includes a frame (1) of elongated floats (2, 3), which are substantially arranged at a right angle to each other and are linked with each other in a T or H configuration. On a first float (2), further floats (3) or sections of floats are mounted on both of the first float's opposite ends. The first float (2) has a top which is turned upwards by 90° compared to its lateral sides on which further floats/float sections (3) are mounted and carries a drive unit (9). This drive unit (9) is mounted completely or partially on the floats, and its output shaft (10) projects outwardly from both sides parallel to the longitudinal extension of the further floats/float sections (3). Paddles (22) are disposed on the output shaft (10) and in the operational state of the aerator, when the floats float on the surface of the water or clearing basin, the shaft rotates above the level of the water or clearing basin, and sections of the co-rotating paddles are immersed in the liquid.
