Abstract: A device for the processing of a barrel of which the upper side comprises a filling hole situated in a standardized position, this device comprising a processing enclosure fitted with a supporting structure bearing a rotary annular part on which the barrel can be disposed, centered and pivoted about its vertical axis of symmetry, and with a purging device comprising a purging rod that is vertically translatable, this rod being disposed to come into line with the axis of the hole subsequent to a rotation of the barrel and to then be inserted inside the barrel by translational motion.

Abstract: The device embodying the invention uses a hydraulic press activating a mobile plate in a chamber opposite a base on which a metal barrel can be disposed, and successively comprises: the placing and maintaining of the barrel on the base; the perforating of two opposite sides of the barrel by means of an elongated perforating mechanism running through the barrel from side to side and from top to bottom; the cleaning of the interior of the barrel by projection of a cleansing fluid under pressure by means of a rotary injection head integral with the perforating mechanism; and the crushing of the barrel by displacement of the plate towards the base. The invention notably concerns the processing of polluted metal barrels with a view to facilitating handling, storage and recycling thereof.
