Abstract
Apparatus for the extraction of objects (32) immobilized in sections (19) of a pneumatic transfer network (30). The apparatus includes a flexible pipe (12), a metal-clad or radiation-impervious container (10) and a blower (5). A flange (16) makes it possible to connect the pipe (12) to the upstream end of the section (19). A suction system then makes it possible to draw the jammed jug (32) to the bottom of the metal-clad container (8) by moving it back into the section (19). Advantageously, the blower (5) is reversible for propelling the jug (32) in the opposite direction to a scrapping installation, to which is connected the flexible pipe (12). Therefore, both the manipulations and the contamination risks are reduced.
