A kind of anode slime automatic cleaning system and anode slime automatic cleaning method

Abstract

The invention discloses an automatic anode slime cleaning system and an automatic anode slime cleaning method, wherein the automatic anode slime cleaning system includes a diversion funnel arranged at the bottom of an electrolytic cell, a sludge discharge pipe, and a filter press. The funnel connects the upper surface and the lower surface of the bottom of the electrolytic cell, and the diversion funnel is a conical structure with an inclination angle of 38-50 degrees. The diversion funnel of the conical structure includes an upper opening on the upper surface of the bottom of the electrolytic cell and a The mud discharge port on the lower surface of the bottom of the electrolytic cell is connected with the mud discharge pipe, and the mud discharge pipe transports the anode slime collected by the diversion funnel to the filter press.

Description

technical field [0001] The invention relates to a collection and treatment system of anode slime, in particular to the cleaning of anode slime in the smelting of electrolytic copper, electrolytic zinc, electrolytic nickel and other non-ferrous metals. Background technique [0002] During the electrolytic refining of non-ferrous metals, some muddy fine-grained substances will gradually accumulate at the bottom of the electrolytic tank. It is mainly composed of impurities insoluble in the electrolyte in the anode crude metal and the metal to be refined. It often contains precious and valuable metals, which can be recycled as raw materials for refining gold, silver and other precious metals. For example, copper can be recovered from the anode slime of electrolytic refining copper, and gold, silver, selenium, tellurium, etc. can be extracted. Anode slime is generally gray, with a particle size of about 100-200 mesh. Each component mostly exists in the form of metal, sulfide, ...

AI Technical Summary

Problems solved by technology

However, due to the following problems in this method, it cannot be truly realized in the actual electrolysis process

[0005] 1. In the process of scraping mud with this method, the anode residue sinks, the wire is cut off, and the equipment is damaged;

[0006] 2. It is difficult to install pulleys and motors on the tank body;

[0007] 3. The scraper is in the process of advancing, causing the electrolyte turbulence in the electrolytic cell, the anode slime floats up, adheres to the cathode plate, affects the quality of cathode copper, and eventually leads to electrolysis failure and cannot meet the electrolysis requirements

[0008] It can be seen that the current collection method of mud scraping technology is a method of discarding the basics and chasing the last, and each manufacturer cannot really put it into actual production
