Description
Technical Field
The invention belongs to the technical field of leaching equipment, and particularly relates to a device for improving the chemical combination leaching rate of low-grade manganese ore.
Background
Manganese series products such as electrolytic manganese dioxide, electrolytic manganese metal, high-purity manganese sulfate, potassium permanganate and the like can not be separated from a manganese sulfate solution, raw materials for producing the manganese sulfate solution are manganese ores (manganese carbonate ores, manganese dioxide ores, manganese oxide ores and the like), the manganese ores are in contact with sulfuric acid to carry out chemical reaction, and the qualified pure manganese sulfate solution is obtained after proper procedure treatment. The index of 'chemical leaching rate' is usually adopted as a measure of the reaction leaching effect of manganese in manganese ore. The combined leaching rate is high, which indicates that the utilization rate of manganese element in the manganese ore is high, the production cost is low, and the economic benefit is good; on the contrary, the chemical combination leaching rate is low, the utilization rate of manganese elements in the manganese ore is low, the production cost is high, and the economic benefit is poor.
The existing leaching device usually only uses blades to accelerate the leaching process, however, the unidirectional blade stirring enables the leachate to rotate only in one direction, the movement locus keeps regular and unchanged, the chemical reaction between substances only normally occurs, the leachate and manganese ore cannot be subjected to more sufficient surface reaction, and the chemical leaching rate of the manganese ore and the utilization rate of manganese elements in the manganese ore are greatly reduced.
Therefore, a device capable of improving the chemical leaching rate of low-grade manganese ore is needed.

The principle and the effect of the technical scheme of the invention are as follows:
when manganese elements in manganese ores need to be extracted to prepare a manganese sulfate solution, corresponding chemical substances are added according to the manganese ore combination leaching condition, then a stirring motor is started, a stirring paddle rotates in a clockwise direction in a stirring mode, manganese ore combination leaching slurry flows along the device in a rotating mode along with the rotation of the stirring paddle, the slurry collides and collides with a turbulence pier in the flowing process, the slurry does not move regularly and unchangeably according to a circular track, but disturbances such as multi-latitude rebound, refraction, cutting and the like occur, large-area particle collision motion and molecular motion are increased to the combination slurry invisibly, chemical reactions among substances do not occur normally but occur abnormally, and therefore the manganese ore combination leaching rate and the manganese element utilization rate in the manganese ores are improved abnormally and effectively.
Furthermore, the turbulence piers of the adjacent turbulence layers are arranged in a 45-degree angle dislocation mode.
The turbulence piers arranged in this way are distributed more evenly, the turbulence effect is better, and the leaching rate is higher.
Furthermore, a clinker outlet pipeline is detachably connected with the leaching tank.
Therefore, after the clinker outlet pipeline is blocked and damaged, the clinker outlet pipeline can be replaced immediately, and the use is convenient and quick.
Further, a plurality of air aeration systems are arranged in the leaching tank, each air aeration system comprises an aeration disc arranged on the inner side wall of the leaching tank, each aeration disc is connected with an air inlet pipeline, and an air inlet control valve is arranged on each air inlet pipeline.
Thus, the air aeration system can aerate the leaching tank to increase the turbulence degree of the leaching slurry, thereby increasing the collision motion and molecular motion of particles in the combined slurry; and meanwhile, the aeration of the aeration disc can also remove iron ions in the leaching solution, so that the purity of manganese in the leaching solution is improved.
