<p>The device for loading a reactor, particularly a rotary drum furnace, with materials to be thermally treated, particularly waste, comprises a loading channel (19) delivering the materials to the reactor, which are introduced therein through a funnel (1), and a sealing device which prevents the penetration and/or the exhaust of gas inside, respectively outside, the reactor. In addition to the funnel (1) there is provided a loading hopper (2) movable between an unloading position located above the funnel (1) and a loading position located beside the funnel (1). The hopper has in its lower portion an obturable opening (3) and an immersion closure device surrounding both the upper opening (4) of the funnel (1) and the lower opening (3) of the hopper (2) as well as another immersion closure (5) surrounding only the lower closure (3) of the hopper. In this other closure, under the hopper (2) inside the closure device, there is provided a hydraulic closure ring (30) immersed in the liquid (7) and which may be lifted or lowered. Upon loading the hopper (2) the ring may be lifted until the edge (6) of the hopper is immersed in the liquid (7) contained therein and until the opening (3) of the hopper is gas-tightly closed. </p> |
