Automatic copper removal system

Abstract

The invention discloses an automatic copper removal system. The automatic copper removal system comprises an air conveying device, an air flow stirring device and a controller. The air conveying device comprises an air conveying main pipe, and one end of the air conveying main pipe is connected with one end of a first air conveying branch pipe and one end of a second air conveying branch pipe; theair flow stirring device comprises a first breather pipe and a second breather pipe, the first breather pipe is arranged in a first liquid making tank, the second breather pipe is arranged in a second liquid making tank, the air inlet end of the first breather pipe is connected with the other end of the first air conveying branch pipe, and the air inlet end of the second breather pipe is connected with the other end of the second air conveying branch pipe; a pressure regulating valve and a pressure sensor are arranged on the air conveying main pipe; control valves are arranged on the first air conveying branch pipe and the second air conveying branch pipe; and the pressure regulating valve, the pressure sensor and the control valves are connected with the controller. According to the automatic copper removal system provided by the invention, a mass transfer effect of a solution in a nickel electrolysis liquid making tank can be automatically improved, and meanwhile, an automatic copper removal function is realized.

Description

technical field [0001] The invention relates to the technical field of metallurgical production, in particular to an automatic decopper system for nickel electrolysis liquid production process. Background technique [0002] The main function of the liquid-making process of the nickel electrolysis process is to electrolyze the external waste liquid containing impurities such as nickel, copper, cobalt, etc. Iron, cobalt removal, and finally transported to electrolysis, so as to achieve the purpose of removing copper and supplementing nickel for the electrolyte in the nickel electrolysis process. Copper removal adopts the operation method of manual shaking of the plate to shake the sponge copper on the cathode to the bottom of the tank. Manual shaking of the plate means that the cathode plate is manually lifted and then mechanically collides with the tank body, causing the sponge copper to vibrate and fall off. The traditional and extensive operation method, The work efficienc...

Problems solved by technology

Copper removal adopts the operation mode of manual shaking of the plate to shake the sponge copper on the cathode to the bottom of the tank. Manual shaking of the plate means that the cathode plate is manually lifted and then mechanically collides with the tank to cause the sponge copper to vibrate and fall off. The operation method is traditional and extensive. The work efficiency is low. At the same time, because the manual shaker requires the operator to stand above the electrolytic tank, there are safety hazards such as objects hitting and falling from heights during operation.
