21427-144 Apparatus for removing sludge from a settllng basin, comprising a pair of longitudinally extending pontoons, spaced apart, and having mounted therebetween, a submersible pump for pumping the sludge. The pump is pivotally mounted between the pontoons and adjustably pivotal from a vertical position to a substantially horizontal position in either direction so as to vary the depth of the inlet to the pump and thereby variably dilute the sludge. Variable pivotal deflector plates are mounted across both ends of the pontoons and include means for deflecting sludge toward the pump inlet. The pontoons are provided with partitions to provide separate compartments which are separately fed with the desired mixture of water and air, to enable tilting of the pontoons as well as providing a variable ballast for submerging the pontoons and pump to the desired depth in the sludge pond. |
