Abstract

Planetary tank coaters employed to fabricate selenium (Se) alloy drums require extensive maintenance to remove alloy deposited on the top half of the chamber. The alloy is chipped off after about 150 to 200 runs. The process of removing this material is time consuming and reduces productivity. Proposed is a partially rotatable vacuum chamber that reduces the maintenance work by a factor of about two and improves the ergonomic impact on the maintenance crew.

Planetary tank coaters employed to fabricate selenium (Se) alloy drums require extensive maintenance to remove alloy deposited on the top half of the chamber. The alloy is
chipped off after about 150 to 200 runs. The process of removing this material is time consuming and reduces productivity. Proposed is a partially rotatable vacuum chamber that reduces the maintenance work by a factor of about two and improves the ergonomic impact on the maintenance crew.

A tank rests on four V pulleys that are set on a ring that encompasses the tank. A motor allows the tank to be rotated. After a build up of selenium occurs, instead of shutting down the production system to clean it, the tank is rotated 180 degrees, so that the area that has the selenium build up is in the lower half of the tank while the clean half of he tank is then utilized as the upper portion of the tank. By modlfylng the deposition system tank to rotate on request, the ergonomics of cleaning the built up selenium is greatly improved.
