  • Patent number: 5466369
    Abstract: A liquid circulating device is provided for submersion in a large holding tank to effect continuous mixing and circulation of a liquid material, such as sewage sludge, contained therein in order to facilitate the digestion of the liquid material for environmentally safe disposal. The device includes an upright, elongated stackpipe secured to the floor of the holding tank and a gas bubble generator mounted to the stackpipe for generating gas bubbles into the stackpipe. The gas bubble generator includes an interior chamber with a substantially open bottom, a pair of baffle members transversely extending within the interior chamber and an inverted cone-shaped member positioned between and in spaced adjacency to each baffle member. Gas under pressure is discharged into the interior chamber of the bubble generator by a gas supply line attached to an externally located compressor.
