Agitator blade for improving leaching rate of metal manganese electrolyte

Abstract

The invention discloses an agitator blade for improving the leaching rate of metal manganese electrolyte. A plurality of layers of agitator blades are arranged, and are fixedly arranged on an agitating shaft coaxial with a leaching groove for the metal manganese electrolyte. The outer end of each agitator blade in each layer of agitator blades is fixedly suspended with a flexible belt; the length of the flexible belt of the agitator blade positioned on the upper layer meets the conditions that: the flexible belt in the vertical state cannot be scratched by the agitator blade on the lower layer, and when the flexible belt is unfolded due to centrifugal force and rotates in ore pulp, the flexible belt cannot be scratched by the side wall of the leaching groove; and the length of the flexible belt of the agitator blade positioned at the lowest layer meets the conditions that: the flexible belt in the vertical state cannot be scratched by a corresponding part at the bottom of the leaching groove, and when the flexible belt is unfolded due to centrifugal force and rotates in the ore pulp, the flexible belt cannot be scratched by the side wall of the leaching groove. The agitator blade can eliminate stirring dead zones under the condition of not increasing energy consumption basically, so the leaching rate of the metal manganese electrolyte can be improved. The agitator blade has the advantages of simple structure and low equipment cost.

Description

Stirring paddle for improving leaching rate of metal manganese electrolyte technical field The invention relates to a stirring paddle in a metal manganese electrolyte leaching tank. Background technique In enterprises that produce electrolytic manganese metal (referred to as electrolytic manganese) by electrolysis, most of them use manganese carbonate (rhodochrosite) as raw material, prepare them into pulp and put them in a leaching tank to leach the electrolyte, and then perform electrolysis. In order to ensure sufficient leaching, stirring paddles for stirring ore pulp are installed in the leaching tanks. The specific structure is that a stirring shaft coaxial with the leaching tank is set in the leaching tank, which is driven by a motor to rotate, and several layers of stirring paddles that are all immersed in the ore pulp are set on the stirring shaft (the number of layers of the stirring paddles According to the depth of the actual leaching tank). When leaching the ...
