Background technique

In the electrolytic copper industry, there are two forms of cathode plates currently used, namely pure titanium panels, titanium-clad copper conductive rods, 316L stainless steel panels, and stainless steel copper-clad conductive rods. Due to the high resistivity of pure titanium and 316L stainless steel, As a result, the current efficiency during electrolysis is low, the energy consumption is high, and the cost of pure titanium panels is high, causing a greater economic burden to the enterprise. The pure titanium cathode plate needs to be manually operated in use, and the monolithic plate is heavier, which brings inconvenience to the operators.

The board panel includes a core aluminum plate and a surface titanium layer. The surface titanium layer covers the two lengths × height planes of the core aluminum plate. There is a strip-shaped gap between the edge of the surface titanium layer near the conductive rod and the conductive rod. The length direction of the gap is parallel to the length direction of the conductive rod, the width of the strip gap along the height direction of the plate panel is 3-5mm, and the strip gap is coated with anti-corrosion paint; the conductive rod includes the core aluminum rod and the outer copper layer , the outer copper layer is sleeved and welded on the outside of the core aluminum rod, the thickness of the outer copper layer is 3-5mm, and one side of the outer copper layer is provided with a through slot for the core aluminum rod and the core aluminum plate to be welded together.

Preferably, a plurality of hoisting holes are opened on the plate panel.

Preferably, insulating edge strips are respectively provided on both sides of the width and height of the pole plate panel.

According to the above-mentioned technical scheme, the beneficial effects of the present invention are:

In the present invention, the two sides of the core aluminum plate of the polar plate panel are respectively covered with surface titanium layers to form a multi-layer structure of "titanium aluminum titanium". Compared with the existing pure titanium panels, more aluminum materials are used as the main raw material. , the conductivity of aluminum is greater than that of titanium and stainless steel, so it has better electrical efficiency and improves the electrical efficiency of the cathode plate. And the density of aluminum is lower than that of titanium and stainless steel, so the weight of a single plate is lighter, which effectively reduces the labor intensity of workers, reduces energy consumption, and improves production efficiency. At the same time, the price of aluminum is much cheaper than that of titanium, so it can bring significant economic benefits and reduce costs.
