Abstract
The invention discloses a stereoscopic fish scale-shaped ore pulp electrolytic cathode device which comprises a conductive copper pipe, wherein one side of the conductive copper pipe is connected with a cathode frame, and stereoscopic fish scale-shaped holes are formed in the cathode frame. The three-dimensional fish scale-shaped holes comprise a plurality of rows of arc-shaped structures, the lower row of arc-shaped structures and the upper row of arc-shaped structures are arranged in a staggered mode, and the arc tops of the lower row of arc-shaped structures press the end portions of the upper row of arc-shaped structures. The aperture ratio of the three-dimensional fish scale-shaped holes is 25-50%. The specific surface area of the three-dimensional fish scale-shaped hole is 1.2-1.5 times of that of the planar open hole. When the area of the electrode is increased, the electrolyte can pass through the cathode electrode, the stirring effect is enhanced, the influence of concentration gradient is reduced, the leaching rate and the current efficiency are improved, and the production capacity of the electrolytic cell is improved.

In prior art, in in-pulp electrolysis groove, conventional anode electrode is graphite rod, and conventional cathode electrode is graphite rod, stainless steel plate or certain metal sheet.
At least there is following shortcoming in above-mentioned prior art:
The electrolyzer that the graphite rod of take is cathode electrode and anode electrode, the product in cathodic area, with sponge state metal powder form output, need add in cathodic area evacuator of pulverized-coal_ sponge state metal powder is extracted out, and will supportingly have filtration, drying installation can obtain primary product; Take graphite rod as anode electrode, the electrolyzer that stainless steel plate or certain metal sheet are cathode electrode, cathodic area product is the sheet metal form output on negative electrode frame with electrodeposition, but is restricted because of cathode electrode area, thereby affected the size that passes into electric current, restricted production capacity.
Summary of the invention
The object of this invention is to provide that a kind of specific surface area is large, leaching yield is high, the solid-fish squamous in-pulp electrolysis cathode assembly of energy efficiency.
The object of the invention is to be achieved through the following technical solutions:
Solid-fish squamous in-pulp electrolysis cathode assembly of the present invention, comprises contact tube, and a side of contact tube is connected with negative electrode frame, is provided with solid-fish squamous hole in described negative electrode frame.
As seen from the above technical solution provided by the invention, the solid-fish squamous in-pulp electrolysis cathode assembly that the embodiment of the present invention provides, owing to being provided with solid-fish squamous hole in negative electrode frame, can increase the area of cathode electrode, in in-pulp electrolysis groove, negative electrode can be realized electrolytic solution water conservancy diversion, when increasing electrode area, electrolytic solution can pass through between cathode electrode, strengthen mixing effect, reduce concentration gradient impact, improve leaching yield and current efficiency, the production capacity that improves electrolyzer, plays the effect of energy efficiency.
