Abstract
The invention discloses an ore separation drum with an ore pulp equal-distribution device. The ore separation drum comprises a cylindrical container with a bottom plate; a plurality of ore pulp outlets are formed in the bottom plate, and circumferentially distributed in the bottom plate; an overflow drum is arranged in the center of the bottom plate of the cylindrical container, and coaxial with the cylindrical container; a straight ore pulp input tube is arranged directly above the overflow drum, coaxial with the overflow drum and the cylindrical container, and also fixed on the cylindrical container; and the diameter of the straight ore pulp input tube is smaller than that of the overflow drum. Ore pulp goes into the ore separation drum via the ore pulp input tube that is upright, and falls into the overflow drum. Because the diameter of the ore pulp input tube is obviously smaller than that of the overflow drum, the ore pulp flow may fall to the center of the overflow drum, or next to the center of the overflow drum. The straight ore pulp input tube that is upright is welded above the ore separation drum when the ore separation drum is manufactured, such that the verticality and the concentricity can be ensured.
