Combined type stirring impeller for increasing leaching rate of manganese metal electrolyte

Abstract

The invention discloses a combined type stirring impeller for increasing the leaching rate of manganese metal electrolyte. The stirring impeller is provided with a plurality of layers which are fixedly arranged on a stirring shaft coaxial with a manganese metal electrolyte leaching tank; and each blade of each layer of stirring impeller is a combined type impeller which is formed by connecting a rigid blade section close to the stirring shaft and a flexible blade section far away from the stirring shaft. The rigid blade section is in a flat-plate shape; and the flexible blade section is a flexible slice or two flexible slices which are clamped at both sides of the rigid blade section. The tail end of the flexible blade section can be comb-shaped if necessary. The flexible blade section of the combined impeller can keep on doing extremely reliable transverse vibration in ore pulp. The combined type stirring impeller has more obvious effects on the aspects of saving energy sources and increasing the leaching rate of the manganese metal electrolyte. When the combined type stirring impeller is applied, the accuracy requirements on the layer numbers and the interlayer spacing of the stirring impeller and the length of the rigid blade section of the stirring impeller are extremely reduced. Therefore, the combined type stirring impeller has the advantage of obviously reducing the comprehensive cost.

Description

technical field [0001] The invention relates to a stirring paddle in a metal manganese electrolyte leaching tank. Background technique [0002] 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 metal manganese electrolyte, the starter motor drives the sti...

Problems solved by technology

Yet, because this application is at the outer end of each original blade, only a flexible band (i.e. a strip-shaped flexible band) is fixedly suspended, so it is too soft and difficult to lift to "sweep". That is to say, it is not very ideal to attempt to reduce the "dead zone" in the pulp by its shaking, or in other words, when the combined paddle of the invention is set for different sizes of leaching tanks, the stirring paddle's The number of layers, the distance between layers, the length of the rigid part of the stirring paddle, etc., still need to be calculated more accurately, or to conduct a relatively large number of tests, in order to achieve better results
