Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cells, in particular to a cobalt electrolytic cell device. Background Art

[0002] The electrolytic cell consists of a cell body, an anode and a cathode, and most of them use a diaphragm to separate the anode chamber from the cathode chamber. According to the different electrolytes, it is divided into three categories: aqueous solution electrolytic cell, molten salt electrolytic cell and non-aqueous solution electrolytic cell. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to produce the desired product. In the existing cobalt electrolytic cell production process, there are at least the following disadvantages: In the existing cobalt electrolytic cell production process, the anode produces waste gas, resulting in serious waste gas overflow at the production site; in the waste gas absorption process, due to the high temperature in the electrolytic cell, the evaporation of the electrolyte will form crystals after condensation in the exhaust gas absorption pipeline, which is easy to block the pipeline, resulting in poor exhaust gas absorption effect; the solution temperature loss in the existing production is relatively fast, which cannot meet the temperature stability in the cobalt electrolysis production process.

A row of tail gas suction holes 2 are arranged on both sides of the inner wall of the electrolytic cell body 1. The tail gas suction holes 2 are respectively connected with the flushing tail gas pipeline inlet 3, the flushing tail gas pipeline outlet 7 and the cell body tail gas absorption pipe 8. The top of the electrolytic cell body 1 is connected to the cell cover 4 through a movable shaft. The electrolytic cell body 1 is provided with cathode and cathode electrodes 9 inside.

The bottom of the electrolytic cell body 1 is provided with a heating device 12.

[0011] The tail gas absorption pipe 8 is connected to the flushing pipeline inlet 3 and the flushing tail gas pipeline outlet 7, and forms a sloped interlayer to facilitate the collection of the solution after flushing. Anodes and cathodes 9 are provided on both sides of the tank and connected to the external silicon rectifier, which are used for the electrolysis busbar in the tank. Anode plates 10 and cathode plates 11 are hung on the busbars on both sides. There are several tail gas suction holes 2 on the upper part of the inner wall of the electrolytic tank body 1, which are connected to the tail gas absorption pipe 8, and the purpose is to quickly absorb the tail gas in the tank.

[0012] In order to maintain the electrolyte temperature in the electrolytic cell, a heating device 12 is installed in the cell, and the device is connected to an external water circulation heating system, through which the electrolyte temperature is maintained at about 80-90°C.

[0013] Working principle: The electrolyte enters the electrolytic cell body 1, and an insoluble anode is used. Direct current passes through the anode and cathode (9) of the electrolytic cell and the cobalt electrolyte, causing the metal ions to be reduced and deposited on the cathode. When the thickness of the cobalt plate reaches the standard, it begins to exit the cell.

[0015] 2) Cathode reaction: Co 2+ +2e - →Co
