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

Embodiment 1

[0048] A kind of anode slime automatic cleaning system, see attached figure 2 , 3 , as shown in 4, figure 2 It is a three-dimensional schematic diagram of the anode slime collection system of the present invention, image 3 for figure 1 front view of the Figure 4 It is a schematic diagram of the bottom structure of the electrolytic cell 100 of the anode slime collection system of the present invention. The automatic anode slime cleaning system of the present invention includes a diversion funnel 1, a sludge discharge pipe 2, and a filter press 3 arranged at the bottom of the electrolytic cell 100, and the diversion funnel 1 communicates with the upper surface 101 and the lower surface 102 of the bottom of the electrolytic cell. The diversion funnel 1 has a conical structure with an inclination angle of 38-50 degrees, and the best inclination angle of the diversion funnel is 45 degrees. The diversion funnel of the conical structure includes an upper opening 11 located o...

Embodiment 2

[0052] Such as Figure 5 , figure 1 as shown, Figure 5 It is a structural schematic diagram of the electrolytic cell and the sludge discharge pipe of the automatic anode slime cleaning system of the present invention. A main pipe 22 is connected to the same row of branch pipes 21 at the bottom of a plurality of side-by-side electrolytic cells; the branch pipes are Y-shaped branch pipes, and one Y-shaped branch pipe is connected to the mud discharge ports of two diversion funnels adjacent to the bottom of the same electrolytic cell , input the anode slime in the two diversion funnels into the main pipe; preferably, one main pipe is connected with the same row of Y-shaped branch pipes at the bottom of multiple electrolytic cells arranged side by side. As a further preferred solution of this embodiment, the bifurcation angle of the Y-shaped branch pipe is not less than 45 degrees. The main pipe is horizontally inclined downward from the end to the end, and the included angle ...

Embodiment 3

[0054] As a further improvement of the present invention, the mud outlet 12 has been thoroughly studied, see Figure 6 , 7 , Figure 6 is a schematic diagram of the structure of an electrolytic cell with a lead plug, Figure 7 yes Figure 6 A partial enlargement of the . The mud outlet 12 adopts a tapered design to ensure that the anode mud does not remain. Simultaneously, the present invention thinks that the internal diameter of the mud discharge port of described diversion funnel is advisable 50-200mm, and 80mm is the best, when mud discharge port 12 is taper design, the internal diameter of said mud discharge port here refers to the mud discharge port. The smallest inner diameter on the mouth. Such an inner diameter ensures that the anode slime does not block the sludge discharge port and does not affect the normal flow of the electrolyte. Also can be equipped with lead plug 8 for described mud outlet 12. The mud discharge port is equipped with a lead plug. When the...

Abstract

The invention discloses an automatic cleaning system for anode mud and an automatic cleaning method for the anode mud. The automatic cleaning system for the anode mud comprises diversion funnels arranged at the bottoms of corresponding electrolytic cells, a sludge discharge pipeline and a filter press. The diversion funnels communicate with the upper surfaces and the lower surfaces of the bottoms of the corresponding electrolytic cells. Each diversion funnel is of a tapered structure with the inclination angle of 38-50 degrees. Each diversion funnel of the tapered structure comprises an upper opening in the upper surface of the bottom of the corresponding electrolytic cell and a sludge discharge opening located in the lower surface of the bottom of the corresponding electrolytic cell. The sludge discharge openings are connected with the sludge discharge pipeline. The sludge discharge pipeline conveys the anode mud collected by the diversion funnels 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, ...
