Electrolytic cell for nickel mineral wet metallurgy

Abstract

The invention discloses an electrolytic cell for nickel mineral wet metallurgy. The electrolytic cell for nickel mineral wet metallurgy comprises an electrolytic cell body, a liquid inlet pipe is arranged at the upper part position of one side of the electrolytic cell body in a penetrating mode, an anode chamber is connected to the middle position of the top of the electrolytic cell body, and a movable cover plate is connected to the position of one side of the top of the anode chamber through a hinge. A screw hole and a handle are separately arranged at the top of the movable cover plate, ananode bar is arranged on the inner wall of the screw hole, and an anode is connected to the bottom end of the anode bar through a connecting piece. According to the electrolytic cell for nickel mineral wet metallurgy, the screw hole and the anode bar are further arranged simultaneously, the anode bar can be rotated during electrolysis, so that the anode bar moves up and down in the screw hole through a thread on the outer surface, a purpose of adjusting the height of the anode is achieved, thus, the anode is in contact with a electrolyte solution more thoroughly, and the working efficiency ofthe electrolytic cell is greatly improved; and the drainage pipe is filled with waste gas generated in the electrolytic cell absorbed by a carbon nano pipe, and pollution to the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of electrolysis for nickel ore hydrometallurgy, in particular to an electrolytic cell for nickel ore hydrometallurgy. Background technique [0002] The electrolytic cell is composed of a cell body, an anode, and a cathode, and most of them are separated by a diaphragm from the anode chamber to the cathode chamber. According to the different electrolytes, it is divided into three types: aqueous solution electrolyzer, molten salt electrolyzer and non-aqueous solution electrolyzer. Existing electrolytic cells for nickel ore hydrometallurgy will produce some poisonous gases when the electrolyte is energized during nickel ore wet electrolysis, and these gases will cause great harm to the environment if they are discharged without treatment. pollution, and cause damage to the health of users; and the existing electrolytic cell is difficult to freely adjust the height of the anode during electrolysis, resulting in...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an electrolytic cell for nickel ore hydrometallurgy to solve the problem that the untreated gas directly discharged in the above background technology will easily pollute the environment and cause damage to the health of users, and it is difficult to damage the anode. The height is adjusted, resulting in insufficient contact between the anode and the electrolyte, which affects the working efficiency of the electrolytic cell
