SLURRY STORAGE TANK WITH STIRRING MEANS

摘要

A slurry storage tank comprises a central vertical column arranged therein. A drive mechanism is mounted on the upper portion of the column. A plurality of rake arms with rake elements are arranged within the tank adjacent to its bottom. The rake arms are slowly rotated about the column by the drive mechanism to direct the lower portion of the slurry toward the side wall of the tank. The slurry is withdrawn from the lower portion of the tank by a pumping means and delivered through a pipe means to a plurality of vertical guide pipes supported by the top wall of the tank and extending into the tank. The withdrawn slurry is distributed over the entire surface of the slurry in the tank through the guide pipes to thereby maintain the slurry in the tank in a homogeneous state.
