Problems solved by technology

[0002] At present, the PCB industry is one of the industries that consume the most copper resources. There are many ways to recover copper from the microetching solution produced by it, such as adding chemical agents, etc., but the recovery rate of copper is not too high, and the cost of chemical agents It is also relatively high, and it also has certain hazards and pollution, which is not conducive to the market competition and social interests of enterprises.
[0003] With the continuous development of electrochemical technology, it has made new breakthroughs in the copper recycling industry. The main components in electrochemistry that have a greater impact on the overall process are electrodes or electrode groups, and most of the existing electrode groups are more complicated to operate. The cost is also relatively high, which brings great inconvenience to the enterprise

Embodiment Construction

[0011] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0012] See attached figure 1 As shown, a copper recovery electrode group of the present embodiment is composed of an anode 1, a cathode 2, an anode copper row 3 and a cathode copper row 4. The anode 1 is an oxygen-evolving titanium anode, and its surface is coated with iridium oxide , tantalum, rhodium, ruthenium, and platinum coatings, for the development of electrodes for copper recovery, which can significantly improve the efficiency of copper recovery. The cathode 2 is made of titanium plates and titanium-clad copper bars to improve its electrical conductivity. 1 is fixed by screws, the cathode copper bar 4 and the cathode 2 are fixed by scre...

Abstract

The invention discloses a copper-recyclable electrode set. The copper-recyclable electrode set is composed of an anode (1), a cathode (2), an anode copper bar (3) and a cathode copper bar (4). The anode (1) is an oxygen evolution type anode, and the anode copper bar (3) is fixed to the anode (1) through screws. The cathode copper bar (4) is fixed to the cathode (2) through screws. The anode copper bar (3) and the cathode copper bar (4) are connected to the anode and the cathode of a direct-current power source respectively. The copper-recyclable electrode set is convenient to operate, low in cost and high in recycle rate.

Description
