摘要：The device comprises a sealed enclosure (1) that communicates with a
generator (20) to generate microwave radiation at a treatment frequency and is providedwith a pivot unit for modifying the inclination of the generator with respect to a verticaldirection, and a metallic tank. The sealed enclosure has a filling opening with a partlocated above an axis of the pivot unit. The metallic tank: opens to the microwavegenerator and to the filling opening to contain the material to be treated used in a cycle;and is rotatable and driven in rotation by a unit for varying its speed. The devicecomprises a sealed enclosure (1) that communicates with a generator (20) to generatemicrowave radiation at a treatment frequency and is provided with a pivot unit formodifying the inclination of the generator with respect to a vertical direction, and ametallic tank. The sealed enclosure has a filling opening with a part located above an axisof the pivot unit. The metallic tank: opens to the microwave generator and to the fillingopening to contain the material to be treated used in a cycle; is rotatable and driven inrotation by a unit for varying its speed so as to optimize the mixing of the material to betreated by radial ribs integral with the tank; is placed in the enclosure; and further
comprises a unit for draining the treated material located in the upper part and usedafter tilting the enclosure and vessel. An impedance of the tank is adjustable by a unit foradjusting the height of the tank. The inner rotatable tank is made of refractory steel withlow resistivity. The enclosure further comprises an outlet adapted to discharge thetreated material by gravitation. A seal made of a braided metal: is positioned betweenthe enclosure and its lid so as to prevent the leakage of microwave radiation; and ispositioned between the enclosure and a rotating shaft leading to the tank so as toprevent the leakage of microwave radiation. The lid comprises a metal chute system, onits side facing the tank, for draining the treated material. The enclosure, the lid and thetank are thermally insulated using insulating materials such as alumino-silicate fibers withlow thermal inertia and are transparent to microwave radiation. The insulating material ofthe lid is fixed by a fastening system compatible with the microwave radiation. Themicrowave generator and a waveguide (21) are mounted integral with the enclosure so asto be pivotable. The device further comprises an automatic clamping system that allowsunlocking and locking of the wave guide to disconnect and reassemble the waveguide tothe enclosure, a quartz window provided at each waveguide flange to prevent dust fromrising to the generator, an air injection system disposed on the waveguide to create theoverpressure inside the generator and to prevent the spread of dust, a non-conventionalmicrowave heating unit configured to preheat the material to be treated, a unit forrecovery heat produced by the treated material, and a unit configured to measure thetemperature of the material to be treated to monitor and regulate the heat treatment.The heat recovery unit is present outside of the enclosure. An outlet is disposed on alower part of the enclosure so as to allow the discharge of dust, debris and particlesejected from the cavity.
