A duct 8 is provided on the right end surface, which is the other end surface of the drum 2. Reference numeral 9 denotes a vertically long collection portion, on the left side of which a duct 10 protrudes,
The duct 8 and the duct 10 are detachably connected. An exhaust duct 11 is provided upright at the upper part of the collecting part 9, and a collecting box 12 for collecting ash A ′ generated as a result of incinerating the filth is detachably mounted at the lower part. By pulling out the duct 8 from the duct 10 to separate the drum 2 and the recovery unit 9, the duct 8 can be easily handled and transported, and by connecting the duct 8 and the duct 10, the duct 8 can be easily assembled.

A sprocket 14 is provided on the outer periphery of the duct 8.
Is installed. Reference numeral 15 denotes a motor, and a sprocket 16 is mounted on a rotating shaft of the motor. A sprocket 14 and the sprocket 16 are tuned with a chain 17. Therefore, when the motor 15 is driven, the drum 2 rotates about the horizontal axis K. The rotation speed is arbitrarily set, but is preferably about 3 to 10 rotations per minute, and more preferably about 5 to 6 rotations per minute. That is, the motor 15, the sprockets 14 and 16, and the chain 17 serve as a rotating unit of the drum 2.

Next, the internal structure of the drum 2 will be described. FIG. 2 is a sectional perspective view showing the inside of the drum 2, and FIG. 3 is a longitudinal sectional view of the same. The drum 2 has a cylindrical shape, and a plurality of ribs 18 (a total of eight ribs, four on each side of the drum 2 in this embodiment) are fixed inside the drum 2 by welding means. The rib 18 has a long plate shape, and is arranged so as to be inclined from the end of the drum 2 toward the center with respect to the longitudinal direction of the drum 2. In FIG. 3, A is a discharge pipe 5

This waste incineration apparatus has the above-described configuration. Next, a waste incineration method will be described. In FIG. 1, the waste in the toilet 1 is discharged into the drum 2 through the discharge pipe 5 together with the washing water. At this time, the motor 15 is driven, the drum 2 is slowly rotating, the burner 6 is also ignited, and the flame is emitted from the tip of the pipe 7. As described above, when the drum 2 rotates, the waste A inside the drum 2 is guided by the ribs 18 and the central portion S in the drum 2 is rotated.
Focus on

Therefore, the tip end portion 7a of the pipe 7 is arranged so that the flame of the burner 6 is radiated toward the collected waste A. Further, since the waste A concentrated in the central portion S is stirred by the ribs 18, the waste A is heated by the flame very efficiently. In addition, since the ribs 18 are also heated by the flame, the ribs 18 become hot, and the ribs 18 come into contact with the contaminants A, so that the contaminants A are also heated by the heat transfer.

When the filth A is heated, the water content evaporates and becomes a gas. The generated gas is pressure-fed to the right by the wind pressure of the flame radiated toward the right end surface of the drum 2, that is, toward the recovery section 9 side. , The duct 8, as indicated by the dashed arrow in FIG.
The air enters the collection unit 9 through the air outlet 10 and is further discharged from the exhaust duct 11 to the outside. Further, even after the water evaporates, the waste A is further burned by being heated by the flame or the heat transfer of the ribs 18 to become ash A '. The ash A ′ is lightweight, and therefore enters the collection section 9 through the ducts 8 and 10 as indicated by solid arrows due to the wind pressure of the flame toward the duct 8 side, and falls into the collection box 12 below and is collected. Is done. Collection box 12
Ash A ′ collected inside is collected in a bag (not shown) or the like by removing collection box 12 from collection section 9.

Various operating methods of this waste incinerator can be considered. That is, the activation of the motor 15 for rotating the drum 2 and the ignition of the burner 6 may be performed by the user of the toilet operating a manual switch, or a sensor for detecting the wash water discharged from the toilet bowl 1. Alternatively, a sensor or the like for detecting the inflow of dirty water into the drum 2 is provided, and the motor 15 is automatically started and the burner 6 is ignited by the detection signal of the sensor. The drive of 15 may be stopped and the burner 6 may be extinguished. Of course, in this case, the drive time of the motor 15 and the burner 6 is from the toilet 1 to the drum 2
It is freely set according to the amount of filth sent to the burner 6 and the strength of the burner 6's heat power.

If the rotation speed of the drum 2 by the motor 15 is too fast, the dirt A inside may be scattered and scattered from the opening 4 to the outside, and if the rotation speed of the drum 2 is too slow, the dirt A Cannot be sufficiently agitated, so that it is desirable to rotate at a speed of about 5 to 6 times per minute as described above. Of course, the rotation speed varies depending on the dimensions of the drum 2 and the like. The opening 4 is opened to insert the exhaust pipe 5 and the pipe 7 into the drum 2. The opening 4 introduces fresh air from the outside into the drum 2 to promote combustion. It has the role of doing. The rib 18 is not necessarily provided, but as described above, the rib 18 has a stirring action and a heating incineration action for the waste A, and therefore the provision of the rib 18 enables the waste A to be burned more efficiently.

Next, another embodiment of the present invention will be described. FIG.
