Abstract

PURPOSE: To restrain a leakage thru a penetrating hole and prevent damages for a driving portion and a stain below a furnace by making a revolving radius of a vane with sweep back angle, provided on a rotatable root-cup covering the penetrating hole at the bottom floor of the furnace, bigger than that of the revolving radius of mixing vanes.
CONSTITUTION: Feeding vanes 8 having a sweep back angle α are fixed to an outer periphery of a root-cup 4 fixed to a vertical shaft 3. The revolving radius RA of the outer end portion of the feeding vane 8 is designed to be bigger than that RB of a mixing vane 6 nearest to the center. After the mixing vane 6 is rotated and passed, burnt residues are being remained in an inner region of the revolving radius RB, however, the residues are scraped out to the outer region of the redius RA when the feeding vanes 8 are rotated and passed, thereby, interposing of the burnt residues below the root-cup 4 may be prevented.
