[0025]
In such a state, the foreign matter taken out from the waste water and dehydrated passes through the chute 31 and is put into the processing container 21 below. The contaminants that have passed through the lower end of the chute 31 are thrown into the processing container 21 from the slide body 32a of the slide body 32 through the upper region of the processing container 21 surrounded by the peripheral surface of the guide body 33. . Drainage impurities falling downward from the slide main body 32 a are guided into the peripheral surface of the guide body 33 fitted in the processing container 21 at the lower end, and are reliably put into the processing container 21. There is no risk of protruding.
[0026]
When the waste contaminants thrown into the processing container 21 are thrown into the processing container 21 almost completely, the state is detected by the full sensor 36. Thereby, the electric cylinder 34 is driven and the piston rod 34a is lowered. When the piston rod 34a is lowered, the entire slide body 32 is lowered, and the pressing plate 32b disposed in the guide body 33 is lowered in the guide body 33, as shown in FIG. 5 (c). The waste contaminants thrown into 21 are pushed into the processing vessel 21. As a result, the waste contaminants thrown into the processing container 21 are filled into the processing container 21.
[0027]
Thereafter, the electric cylinder 34 is driven and the piston rod 34a is raised to the state shown in FIG. 5 (d). Further, as the piston rod 34a is raised, as shown in FIG. 5 (a), the guide The body 33 is lifted upward by the pressing plate 32 b of the slide body 32 and is positioned above the processing container 21.

In this way, when the processing container 21 is filled with the waste contaminants, the container turning body 20 is swung horizontally by 180 degrees by the turning motor 12 and the processing container 21 into which the waste contaminants are charged. Is disposed in the incineration chamber 11. At this time, the processing container 21 initially disposed in the incineration chamber 11 is disposed below the guide body 33 lifted upward by the slide body 32, and the waste contaminants are removed by the same operation as described above. The processing container 21 is filled.
[0029]
While the processing container 21 below the guide body 33 is filled with impurities, the waste water in the processing container 21 disposed in the incineration chamber 11 is incinerated. In this case, the incinerator main body 11 generates microwaves from the magnetron 13, and the generated microwaves are passed through the waveguides 14 to the waste contaminants in the treatment container 21 disposed in the incinerator 11. Irradiate. When the waste water in the processing container 21 is irradiated with microwaves, moisture is evaporated and dried, and combustible gas is generated. Then, the combustible gas is ignited by the electronic ignition device 16 and the waste water in the processing container 21 is combusted. When the waste contaminants in the processing container 21 are combusted, the waste contaminants are carbonized, and the carbonized waste contaminants are combusted by the microwave irradiated from the magnetron 13.
[0030]
In this way, when the waste contaminants in the processing container 21 are completely incinerated, the processing container 21 is forcibly cooled, and the container turning body 20 is rotated 180 degrees horizontally. As a result, the processing container 21 in which the incineration ash of the waste contaminants is accommodated is disposed below the chute 31 outside the incineration chamber 11, and the processing container 21 into which the waste contaminants are charged by the chute 31 is in the incineration chamber 11. Placed inside. And the waste-water impurities of the processing container 21 arrange | positioned in the incineration chamber 11 are incinerated as mentioned above.
[0031]
When the processing container 21 in which the incinerated ash of the waste contaminants is accommodated is disposed below the chute 31, the reversing motor 23 is driven, and the processing container 21 is inverted about 180 ° around the horizontal axis 24. In this case, the guide body 33 provided below the chute 31 is in a state of being lifted upward by the slide body 32 slid upward, and the processing container 21 reversed around the horizontal axis 24 is the guide body. There is no possibility of colliding with 33. When the processing container 21 is turned upside down, the incineration ash of the waste contaminants housed in the processing container 21 is discharged into an appropriate container disposed below the processing container 21. Thereafter, the processing container 21 is inverted by 180 ° around the horizontal axis 24, and the inside of the processing container 21 is opposed to the lower end of the chute 31, so that the waste contaminants introduced from the chute 31 are treated as described above. The container 21 is filled. Thereafter, the same operation is repeated.
[0032]
【The invention's effect】
In the waste incineration apparatus of the present invention, the guide body is slidable in the vertical direction through the pressing plate at the lower end portion of the chute as described above, and the processing container is arranged below the chute. In addition, since the lower end portion of the guide body is fitted into the processing container, the waste contaminants falling from the chute are guided by the guide body and reliably put into the processing container. Accordingly, there is no possibility that the waste contaminants thrown into the processing container protrude from the processing container. Further, when the processing container is rotated around the horizontal axis, the guide body is slid upward, so that the guide body does not collide with the processing container. Furthermore, since the guide body is provided with a pressing plate that pushes the waste impurities introduced into the processing container into the processing container, the waste impurities introduced into the processing container by the pressing plate are contained in the processing container. By being pushed in, it is more reliably prevented that the waste contaminants protrude from the processing container .
