Abstract
A floating vertical shaft downflow directional mixer apparatus including a float, a motor driven propeller mounted on an upright propeller shaft below the float, and a draft tube extending downwardly from the float and having a lateral discharge outlet. The float is arranged to support the mixer with the propeller shaft generally upright when the mixer is not in operation. The draft tube and lateral discharge outlet are bilaterally symmetrical with respect to a median plane and a thrust reaction line is attached to the lower portion of the draft tube generally symmetrical to the median plane to counteract the reaction forces on the mixer produced by the stream discharged from the discharge outlet and maintain the propeller shaft generally upright when the mixer is in operation.
