It can be used for various purposes in various fields. For example, if waste discharged as slurry or the like from various industrial facilities is subjected to drying or melt-solidification treatment by microwave irradiation, its volume can be significantly reduced, which is convenient for subsequent processing. In addition, waste containing radioactive materials discharged from nuclear facilities must be isolated from the human environment and stored in a containment facility for a long period of time after collection. If "volume reduction treatment" is applied, it will reduce the number of storage containers and storage facility space, increase storage capacity, reduce the amount of handling work, etc., and is extremely advantageous economically.

(Reference) related to improvements. Patent application No. 1987-49599 discloses a microwave melting furnace that heats and melts a workpiece charged in a crucible by irradiating microwaves to the workpiece,
An upper furnace body is provided with a waveguide and a tuner connected to a microwave oscillator, and a processing material supply pipe and fixed to a support, and a rotary table having a vertical axis at the bottom. a lower furnace body on which a melting crucible is mounted, and the lower furnace body is detachably attached to the upper furnace body,
Alternatively, the lower furnace body is further provided with an inert gas introduction pipe, and the inert gas supplied from the inert gas introduction pipe is used to make the pressure between the inner wall of the lower furnace body and the crucible positive with respect to the pressure inside the furnace. A batch melting type microwave melting furnace is disclosed. Since the above invention has such a configuration, the melting crucible rotates in the furnace and irradiation is uniformly applied to the workpiece, so that the workpiece can be heated and melted efficiently and smoothly. In addition, since the inside of the furnace can be made into an inert gas atmosphere, it is possible to prevent reactions between the processed material and the atmosphere inside the furnace due to the chemical and physical properties required for melting and solidification. The effect of reducing oxidative wear and tear on the crucible itself can also be obtained.

However, even if the crucible on the two-turn table extends upward due to thermal expansion, it is necessary to provide a considerable gap so that it does not come into contact with the upper furnace body, and microwave leakage still exists. In addition, there remain problems such as the bottom surface of the crucible placed on the three-turn table being susceptible to oxidation due to poor contact with the inert gas.

can be retracted from the upper furnace body 1 to the position 2'.
As shown in FIG. 2, the lower furnace body 2 includes a lower furnace body 21, a rotary container 12 that is rotatably housed in the lower furnace body, and a crucible 8 that is housed in the rotary vessel 12 and rotates. Be prepared. The peripheral wall of the lower furnace main body 21 has a double structure consisting of an outer wall 21a and an inner wall 21b.
A heat insulating material 13 is provided in the gap b and the inner surface of the inner wall 21b.

On the other hand, the bottom surface 21c of the lower furnace body has a substantially disk shape, and an annular protrusion 21e protrudes around the central bearing 21d. The rotating container 12 has a substantially cylindrical shape, has an outer edge 12b projecting outward from the upper part of the peripheral wall 12a in an L-shaped cross section, and is suspended from the bottom surface 12c, and is combined with an annular protrusion 21e on the bottom surface 21c of the lower furnace body.

活性ガスとともに排気管７より排出される。 Therefore, in order to perform a melting process using the melting furnace of the present invention, the rotating container 12 is first screwed and fixed to the shaft core 14 and housed in the lower furnace body 2, and then the crucible 8 is suspended in the rotating container 12. After storing, the lower furnace body 2 is attached to the upper furnace body 1 by rotating and raising/lowering the holding machine 10. Next, inert gas is applied to the shaft core 14.
is introduced into the rotating container 12 through. The inert gas is introduced into the rotating container 12 through the boundary between the heat insulating material and the rotating container 12 when the heat insulating material 13c is an alumina block, or through the inside of the heat insulating material when the heat insulating material 13c is made of fibrous carbon. It may also be introduced through an opening in the center of the insulation material. The inert gas is then introduced into the annular groove through the contact between the rotating container 12 and the crucible 8. Alternatively, the inert gas may be introduced through a plurality of through holes provided near the upper end of the peripheral wall 12a of the rotating container 12. In this way, the gap between the crucible 8 and the rotating container 12, the inside of the crucible 8, and the inner surface of the lower furnace body 2 are made into an inert gas atmosphere, and then the object to be treated is introduced into the crucible 8 through the supply pipe 5. The position of the tuner 4 is adjusted by the driving motor m1 , and microwaves are guided into the furnace from a microwave oscillator (not shown) through the waveguide 3, and the crucible 8 is rotated together with the rotary container 12. The object to be treated is irradiated. The generated dust and fumes are discharged from the exhaust pipe 7 together with the inert gas.

Since it has a rotating container that can be attached to and removed from the rotating shaft core, even if a hole is made in the crucible due to local heating and the melt flows out, it will not reach the shaft core and will remain within the rotating container. It can be removed together with the holder without reducing the operating rate. In addition, since the crucible is suspended and supported on the upper end of the rotating container by the overhanging part of the upper edge, there is almost no upward expansion due to heat during melting. In this case, it is possible to make the circuit (which forms the chain yoke circuit) extremely small, reliably prevent leakage of microwaves, and prevent seizure of the rotating container.
Furthermore, since the crucible is suspended and supported, the entire surface including the bottom surface of the crucible becomes an inert gas atmosphere, thereby preventing oxidative damage.
