Method and apparatus for cleaning dust from the exterior of capsules
Abstract
Abstract A METHOD AND APPARATUS FOR CLEANING DUST AWAY FROM THE EXTERIOR OF CAPSULES. THE CAPSULES WHICH ARE TO BE CLEANED ARE INTERMINGLED WITH ELECTROSTATICALLY CHARGED PELLETS WHICH ATTRACT THE DUST AWAY FROM THE CAPSULES ONTO THE PELLETS. THE CAPSULES AND PELLETS ARE FED TOGETHER TO A GIVEN LOCATION WHERE THE PELLETS WITH THE DUST THEREON ARE SEPARATED FROM THE CAPSULES SO THAT THE LATTER CAN BE COLLECTED IN CLEANED CONDITION. THE PELLETS WITH THE DUST THEREON ARE THEN BLOWN UP INTO A SUPPLY TOWER FROM WHICH THE DUST IS ELIMINATED BY A VACUUM SO THAT IN THIS WAY THE PELLETS ARE CLEANED. AS THE PELLETS FALL DOWN THROUGH THE TOWER THEY BECOME AGAIN ELECTROSTATICALLY CHARGED, AND UPON REACHING THE BOTTOM OF THE TOWER, THE PELLETS MEET WITH THE DUST-COVERED CAPSULES TO AGAIN BE FED WITH THE LATTER SO THAT IN THIS WAY THE PELLETS ARE CONTINUOUSLY RECYCLED.
