Blowing combined tank in electrolytic manganese process

Abstract

The invention discloses an air-blasting chemical combination barrel in an electrolysis technique of manganese. The air-blasting chemical combination barrel comprises a barrel body, a motor, a speed reducer and a stirring shaft, wherein the stirring shaft is inserted into the barrel body; the motor and the speed reducer drive the stirring shaft to rotate; a two-layer stirring paddle is fixed on the stirring shaft; an air ring formed by a taper-surface ring and a sieve hole cylindrical-surface ring is arranged at the interior of the barrel body; the front end of an air blasting pipe is fixed on the air ring; an air outlet of the air blasting pipe is formed in a high position of the interior of the air ring. Through the air-blasting chemical combination barrel, the air ring formed by the taper-surface ring and the sieve hole cylindrical-surface ring is ingeniously used; the oxygen dissolving capability of the chemical combination barrel is greatly improved; the process of oxidation reaction and the subsequent electrolysis operation are facilitated; and the air-blasting chemical combination barrel is simple and reliable in structure and wide in application prospect.

Description

technical field [0001] The invention relates to a compounding device, in particular to a blasting compounding barrel in the electrolytic manganese process. Background technique [0002] Electrolytic manganese is a hydrometallurgical process in which manganese ore is pulverized, compounded, impurity removed, blended and then electrolyzed. Compounding is the process of slurrying manganese ore powder in a compounding tank and adding sulfuric acid for chemical reaction. Compounding can obtain soluble manganese sulfate, which is convenient for later electrolysis operation. [0003] At present, the volume of the compounding tank for industrial application can reach hundreds of cubic meters. During the compounding process, it is necessary to blow air into the compounding tank to realize the oxidation and decomposition of some impurities and the overflow of some harmful gas substances, which is not only beneficial to protect the environment, but also The realization of electrolyte ...

Problems solved by technology

[0004] However, blowing air into the compounding barrel for impurity removal reaction is restricted by the condition of low oxygen solubility, so in practical applications, a large flow of air is generally blown in, and the bottom of the multi-tube compounding barrel is introduced to promote oxidation, but there is also a large energy consumption. , the defect of low efficiency
