SCREEN BOWL TYPE DECANTER TYPE CENTRIFUGAL SEPARATOR

摘要

PROBLEM TO BE SOLVED: To provide a screen bowl type decanter type centrifugal separator by which filtration of crystals can be continuously and stably performed better than the conventional screen bowl type decanter type centrifugal separator wherein a parallel part with a small diameter of an outside rotating cylinder is constituted as a filter medium part and recovery efficiency of the crystals is improved. SOLUTION: Two conveyors consisting of a main conveyor 8a wherein a gap in the radial direction between the conveyor blade 8 and the inner wall of a filter medium part 10 is enlarged as a screw conveyor in the filter medium 3b and at least one sub-conveyor 8b wherein it is arranged between pitches of the main conveyor and a gap in the radial direction between the conveyor blade and the inner wall of the filter medium part 10 is made small than that in the main conveyor 8a, are provided.
