Title:
低速担体浮遊機
Document Type and Number:
Japanese Patent JP4230023
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent precipitation by allowing sewage sludge to generate turbulent flow between the bottom end part of the rotary shaft of a low speed carrier floatation machine and the center part of the tank bottom of a reactor and allowing the carrier just precipitating to be accelerated in flow to increase floatation effect. SOLUTION: Relating to the carrier floatation machine, the rotary shaft 4 is vertically provided in the reactor 1 and an agitation blade 5 is provided at the rotary shaft 4, and the sewage sludge in the reactor 1 is made to flow by the rotation of the agitation blade 5. In such a case, an agitation auxiliary blade 7 allowing the sewage sludge W to generate the turbulent flow between the bottom end part of the rotary shaft 4 and the center part 6 of the tank bottom is mounted at the bottom end part of the rotary shaft 4.
