Abstract
An improved galvanizing device for the galvanic precipitation of aluminum from an anhydrous, aprotic, and oxygen-free aluminum-organic electrolyte is provided. The original device having an annularly shaped galvanizing trough, which is sealed from the atmosphere, and which utilizes a centrally located and rotatable contacting and holding mechanism for guiding the goods carriers around and through the electrolyte is herein provided with separate charging and discharging locks attached to the galvanizing trough. Each of the locks is provided with a U-shaped fluid lock to maintain the gaseous seal and an endless chain conveyor to transport the goods carrier to and from the galvanizing trough.
Claims7
An improved galvanizing device for the galvanic precipitation of aluminum from an anhydrous, aprotic, and oxygen-free aluminum-organic electrolyte of the type having an annularly shaped galvanizing trough, which is sealed from the atmosphere and chargeable with a protective gas, and a rotatable contacting and holding device, located at a vertical rotational axis of the trough, the device having a plurality of support arms radiating outwardly from the rotational axis, with goods carriers able to be selectively attached to the support arms for passage around and through the galvanizing trough, wherein the improvement comprises:
- a charging lock;
- and
- a discharging lock, both of said locks attached to the galvanizing trough and each comprising:
- a preliminary chamber,
- a main chamber,
- a U-shaped fluid lock connecting said preliminary chamber to said main chamber, forming a gaseous seal, and
- an endless chain conveyor attached to and running continuously through the preliminary chamber, the main chamber, and the fluid lock, whereby the goods carriers may be conveyed through the chambers of the charging lock, into the galvanizing trough, and through the discharging lock, thereby maintaining the protective atmosphere of the galvanizing trough.
