Device for carrying out chemical combination and efficient filter pressing in manganese electrolyzing process

Abstract

The invention discloses a device for carrying out chemical combination and efficient filter pressing in manganese electrolyzing process. An inlet pipe branch I is connected with an outlet pipe through a three-way plug cock and a centrifugal pump; a branch II is connected with the outlet pipe through the other centrifugal pump and the other three-way plug cock; a driving gear is arranged between gears of the two three-way plug cocks and is used for simultaneously driving the two three-way plug cocks to rotate and switch, and the two three-way plug cocks are communicated up and down through a middle connection pipe; the inlet pipe is connected with a manganese solution flowing groove; the flowing groove has a reversed-tapered-shaped bottom structure; two sets of filter presses are connected in parallel and are connected with the outlet pipe through the three-way plug cocks; the flowing groove is connected with an air blowing chemical combination barrel. According to the device disclosed by the invention, the two three-way plug cocks are ingeniously utilized, and the serial and parallel connection of the centrifugal pump can be conveniently operated and the filter pressing efficiency is improved; the device has the characteristics that the structure is simple and the operation does not easily go wrong; the tapered bottom of the flowing groove is good for the output of the manganese solution and mineral dreg; the air blowing chemical combination barrel ingeniously utilizes an air ring body composed of a tapered ring and a sieving hole column surface, so that the oxygen dissolving capability of the chemical combination barrel is extremely improved, and the proceeding of an oxidization reaction and the subsequent electrolyzing operation are facilitated.

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
