SYSTEM FOR THE CONTAINED TRANSFER OF PARTICULATES

摘要

An economical and reliable system for the contained transfer of particulates by means of a series of transfer containers (140) facilitates the particulat e transfer without either exposure of the operating personnel and the environment to the particulate, or environmental contamination of the particulate itself. The system employs a multiple o-ring canister assembly (110) which can be attached to either the discharging port (120) or charging port (135) of a piece of processing equipment. The canister has a series of circumferential o-ring grooves (115) which allows the attachment of a series of individual containers. In a charging mode, once the particulate is charge d to the processing equipment, a first transfer container is collapsed and a second transfer container is placed in the next o-ring groove, thereby containing the remaining contaminated section (149) of the first transfer container. The first transfer container is removed through a bag-out sleeve (143) which is an integral part of the second transfer container. The proces s is repeated in a stepwise fashion by moving to the next groove in the canist er until the process equipment is completely charged in a particulate contained manner.
