PURPOSE:To scatter sludge which has gone up in a draft tube and has entered a cuved cylinder for scattering a liquid, on distant places from an upper opening by centrifugal force, by providing this curved cylinder to a shaft of an agitator. CONSTITUTION:A curved cylinder 14 for scattering a liquid, whose lower opening 15 is concentrical with a shaft 12 and faces a screw 13, and whose upper opening 16 turns sideway and is gradually smaller in diameter toward the upper direction is provided on the upper part of the screw 13 of the shaft 12. In this way, sludge goes up in a draft tube, and then flows in from the lower part of the curved cylinder 14 which is rotating, is scattered in the distance from the upper part by centrifugal force, and the agitation effect is enhanced remarkably. |
