SU129336A1 - Electrolytic bath to produce silver powder - Google Patents

Description

In the existing industrial practice, when obtaining a silver powder by electrolysis, removal of the powder from the cathodes and its discharge of the TS electrolysis baths is manual, as a result of which the process of electrolyzing by this method is very laborious and inefficient, and maintenance of the electrolyzer is associated with the use of heavy manual labor.

The design described mechanizes the removal operations from the cathode and the unloading of the silver wirewatch from the wain, thereby improving; working conditions, and the process itself is more productive.

FIG. 1 shows the electrolyzer in vertical section; in FIG. 2 - the same, top view; n.a fig. 3 - the same, side view.

The electrolyzer has an iron casing 1 lined inside the vnnplast 2. A tube 5 is lined up along the vanilla axis, lined with vinyl plastic outside, inside which passes an aluminum shaft 4 se with a hub 5 at the upper end, which serves to fix a rotating aluminum cathode 6. To the top of the casing an aluminum cover 7 is attached, which is an anode shell. In the lid, grooves are cut along the circumference of the cathode for suspending the silver anodoch 8 and the groove for passing the scraper. On the lid 7, a mechanism is installed to secure and tension the scraper.

Using a scraper made of vinyl plastic, the powder is removed from the cathodes and sent to the hopper 10, from where it is discharged by an excavator-type mechanism 11 equipped with buckets 12.

The electrolyte is supplied to the bath through pipe 13, and the drain to pipe 14. Current is supplied to the rotating cathode through a bath filled with mercury and a bus attached to it — wire; IT motor-generator.
