technical field

The utility model relates to an automatic zinc stripping machine, in particular to an automatic zinc stripping machine with a device for cleaning zinc flakes.

Background technique

In the production process of electrolytic zinc, when the cathode zinc is discharged from the tank, the surface of the zinc sheet often adheres to the electrolyte, and a small amount of anode sludge is locally adhered to the surface of some cathode zinc, which leads to an increase in the lead content of the zinc sheet and affects the quality of the zinc sheet.

At present, the zinc flakes are usually peeled off from the cathode plate by an automatic zinc stripper. Then, through a separate cleaning process, the above-mentioned pollutants are cleaned. Manual operation requires an increase in the workload of workers and labor costs; when an automatic cleaning line is used, it needs to occupy a certain space, and it is difficult to add cleaning stations to the existing production line. The splash of high-pressure water used can easily corrode peripheral equipment.

By setting up a dust cover, prevent other dirt from falling into the filter area.

As a preferred solution of the present invention, the water spray angle of the spray hole is deflected downward by 10-30 degrees.

The spray holes are inclined downward, so that the water flow has a downward component force, which is conducive to the downward movement of the dirt under the impact of the water flow. When the angle is too small, the downward component force is insufficient; when the angle is too large, the horizontal component force of the water flow is reduced, and the lateral impact on the dirt is insufficient.

As a preferred solution of the present invention, the water spray angle of the spray holes is deflected downward by 15-20 degrees.

2. The automatic zinc stripping machine with the zinc flake cleaning device of the present utility model, by setting a water collecting tank with a filter screen, realizes the water circulation and at the same time avoids the blockage of the water pump and the spray pipe, and also avoids the particles in the water flow to the zinc. damage and secondary contamination.

3. The automatic zinc stripping machine with the zinc flake cleaning device of the present utility model, by reasonably setting the spray angle of the spray hole, makes the horizontal and downward force of the water flow more suitable for cleaning the dirt on the zinc flakes, reducing the cleaning time. required water pressure.
