Electrolytic cell measuring robot system

Abstract

The invention discloses an electrolytic cell measuring robot system comprising a guide rail, a measuring robot arranged on the guide rail and walking along the guide rail, a temperature sensor, a manganese ion concentration sensor, a PH sensor, an electrical conductivity sensor, and a robot room arranged at the end of the guide rail. When the system is working, the measuring robot moves along the guide rail to a preset measuring point, and a lifting drive device sends the sensors down to an electrolytic cell to automatically measure the parameters of electrolyte. Measurement is quick and highly accurate, and a strong data support is provided for the improvement of the yield of electrolytic manganese. After measurement at one measuring point ends, the measuring robot can spray water and wash the sensors through a water pump and a high-pressure spray nozzle to clear the electrolyte on the sensors, so the accuracy of next measurement is improved. After completion of measurement, the measuring robot can be maintained in the robot room, such as being cleaned, charged and filled with water. Therefore, smooth measurement is guaranteed, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of electrolytic manganese, in particular to an electrolytic cell measuring robot system. Background technique [0002] The electrolytic manganese process uses manganese sulfate or chloride as the electrolyte, adds certain supporting electrolytes and additives, applies a certain current in the diaphragm electrolyzer, and produces sheet-like manganese metal on the cathode plate. The following reactions take place during electrolysis: [0003] Cathodic electrolysis of manganese, side reaction of hydrogen evolution: Mn 2+ +2e-=Mn↓ [0004] 2H + +2e - =H 2 ↑ [0005] Anodic electrolytic reaction of manganese: Mn 2+ +2H 2 O-2e - =MnO 2 ↓+4H + [0006] 2H 2 O-4e - =O 2 ↑+4H + [0007] For the above-mentioned complex reaction system, to be able to produce manganese metal by electrolysis requires strict control of electrolysis conditions, such as current density, manganese content in bath, pH value, ...

Problems solved by technology

Too high or too low manganese ion concentration is not conducive to the normal progress of manganese deposition

If the Mn in the catholyte 2+ If the concentration is too high, it will lead to the precipitation of high manganese double salt, destroy the electrolysis process, and easily generate Mn(OH) 2 Precipitation, resulting in impure product; if Mn 2+ If the concentration is too low, the depletion of manganese will obviously occur, and the current efficiency will be reduced due to serious concentration polarization, the deposition rate of Mn will be reduced, and shelling will easily occur
