TRANSPORTSYSTEM, INSBESONDERE ZUM TRANSPORTIEREN VON SILIZIUMEINKRISTALLEN DURCH DAS BECKEN EINES FORSCHUNGSREAKTORS

摘要

The invention relates to a transport system for transporting containers (11) or goods inside and along an essentially vertical tube (5, 6) while the containers (11) rotate about the axis of the tube. To obtain a simple construction despite the confined space, the tube is designed as a vertical tube (5) to which is connected a threaded sleeve (6) secured to the end of the transport section so as to remain fixed during rotation. The container (11) has noses (14) which engage in longitudinal guide grooves (15) in the tube (5). These noses (14) also engage in the threaded groove (16) of the threaded sleeve (6). The containers (11) have couplings, e.g. a front toothing (13), at the top and bottom, which transmit a rotary movement from container to container during the transport of a train of contiguous containers, but also allow the containers (11) to be separated from each other in the direction of the axis of the tube. During one rotation of the tube (5), the containers are successively screwed through the threaded sleeve (6), which accomodates at least one container (11). The transport system is particulary suitable for transporting silicon monocrystals in the container (11) through the heavy water tank (2) of a research reactor in order to dope the silicon monocrystals by neutron bombardment.
