A device for compounding and high-efficiency pressure filtration in the electrolytic manganese process

Abstract

The invention discloses a device for compounding and high-efficiency pressure filtration in the electrolytic manganese process. One branch of the inlet pipe is connected to the outlet pipe through a three-way cock and a centrifugal pump, and the second branch is connected through another centrifugal pump and another three-way cock. There is a driving gear between the gears of the two three-way cocks, which simultaneously drives the two three-way cocks to rotate and switch, and is connected up and down through the middle joint pipe; the inlet pipe is connected to the manganese solution flow tank, and the flow tank has an inverted tapered bottom structure ; After the two filter presses are connected in parallel, the outlet pipe is connected through a three-way cock; The invention cleverly uses two three-way cocks to realize the convenient switching operation of the centrifugal pump in series and in parallel, improves the filter press efficiency, has the characteristics of simple structure and easy operation error; Output: The air-blast compounding barrel cleverly utilizes the gas ring formed by the cone surface ring and the sieve hole cylindrical surface ring, which greatly improves the oxygen dissolving capacity of the compounding barrel, which is beneficial to the oxidation reaction and the subsequent electrolysis operation.

Description

technical field [0001] The invention relates to a device for compounding and high-efficiency pressure filtration in an 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 refin...

Problems solved by technology

[0007] However, in the filter press operation, the existing centrifugal pumps cannot automatically adapt to such a process to achieve an ideal working state of high efficiency and high quality

Generally, when a centrifugal pump performs filter press operation, the head of the filter press is low in the early stage, but the flow rate is large, so that the motor is in an overload state, and it is easy to burn the motor; The flow rate decreases rapidly. At this time, although the motor works in a light-load and low-power state, the filter press efficiency is very low; although the filter press pump has the maximum head output state, due to the small flow rate of the filter press fluid, the filter press cannot be fully utilized. Work performance and improve work efficiency
