Description

A kind of electrolytic zinc cathode plate

【Technical field】

The utility model relates to an electrolytic equipment accessory, in particular to an electrolytic zinc cathode plate.

【Background technique】

In the heavy non-ferrous hydrometallurgy industry, the electrolytic equipment currently used for the electrolysis of zinc, copper, and manganese, in order to separate the cathode plate into two mutually independent electrodeposited surfaces, so as to facilitate the stripping of the electrolytic layer, and also to avoid the separation between the cathode and the anode. For short circuit, it is generally necessary to install insulating strips on both sides of the cathode plate. The disadvantages of this type of cathode plate are: 1. The upper end of the cathode plate is exposed to the electrolyte for a long time, and it is very easy to be corroded and induced. 2. The insulation strips on both sides of the cathode plate are generally installed by hot pressing, and the insulation strips cannot be organically bonded to the pole plate. After repeated use It is easy to loosen and fall off, and re-installation will affect normal production.

【Content of utility model】

The technical problem to be solved by the utility model is to provide an electrolytic zinc cathode plate which can effectively prevent the upper end from corroding and whose insulating strip is not easy to fall off, so as to overcome the above-mentioned shortcomings in the prior art.

The technical solution to solve the above problems is: an electrolytic zinc cathode plate, including a pole plate, insulating strips are installed on both sides of the pole plate, and an anti-corrosion strip is installed on the exposed part of the top of the pole plate above the electrolyte.

Its further technical solution is: the insulating strip and the anti-corrosion strip are made of synthetic materials, and are integrated with the pole plate through bonding, heating, and vulcanization;

The insulating strip and the anti-corrosion strip are made of synthetic materials, and are integrated with the pole plate by applying a layer of adhesive layer on the surface where the insulating strip and the anti-corrosion strip are bonded to the pole plate.

Its further technical solution is: the synthetic material is TPE improved rubber synthetic material.

Due to the adoption of the above technical scheme, a kind of electrolytic zinc cathode plate of the utility model has the following beneficial effects:

1. Since the upper part of the cathode plate is exposed to the electrolyte for a long time, there are anti-corrosion strips attached, and the upper part of the cathode plate will not be damaged by the corrosion of harsh gases, thus prolonging the service life of the cathode plate;

2. Because the insulating strips on both sides of the cathode plate and the anti-corrosion strip on the upper end are integrated with the pole plate through bonding, heating, vulcanization, or by applying a The adhesive layer and the polar plate are pressed together to form a whole. The insulating strip and the anti-corrosion strip can be organically bonded to the polar plate, and the connection is firm and not easy to fall off.

Below in conjunction with accompanying drawing and embodiment the technical feature of a kind of electrolytic zinc cathode plate of the present utility model is further described:

【Detailed ways】

Embodiment one:

An electrolytic zinc cathode plate, comprising a pole plate 1, insulating strips 2 are installed on both sides of the pole plate, and an anti-corrosion strip 3 is installed on the top of the pole plate exposed above the electrolyte, and the insulating strip 2 and the anti-corrosion strip 3 are both Made of synthetic materials. When making, first apply a layer of glue on both sides and the upper end (both sides) of the cathode plate 1, stick the insulating strip 2 on both sides of the pole plate 1, stick the anti-corrosion strip 3 on both sides of the upper end of the pole plate 1, and then put it into the mold Medium heating and vulcanization treatment to make it integrated with the pole plate 1. Both sides of the cathode plate can be punched with small holes in advance, so that the synthetic materials on both sides after the vulcanization treatment can pass through the small holes to be integrated; it is also possible not to punch holes, but the connection effect is not as good as the punched holes.

Embodiment two:

An electrolytic zinc cathode plate, comprising a pole plate 1, insulating strips 2 are installed on both sides of the pole plate, and an anti-corrosion strip 3 is installed on the top of the pole plate exposed above the electrolyte, and the insulating strip 2 and the anti-corrosion strip 3 are both Made of synthetic materials. When installing, first apply a layer of adhesive layer on the surface where the insulating strip 2 and the anti-corrosion strip 3 are attached to the pole plate, then paste the insulating strip 2 on both sides of the cathode plate 1, and stick the anti-corrosion strip 3 on the cathode plate The two sides of the upper end of the pole plate 1 are pressed tightly so that they are bonded together with the pole plate.
