2. Description of the Related Art Garbage discharged from food factories, hotels, restaurants, apartment houses, etc. has problems such as decay, an increase in the area of garbage storage, and an increase in collection fees for disposal companies, and collection and transportation. It has problems such as cost increase and labor shortage, and also has problems such as measures for incinerators and landfills, and volume reduction, volume reduction, prevention of decay, and deodorization of garbage have become major issues. I have.

[0003] For this purpose, conventionally, an electric heater is applied to the outer periphery of the stirring and drying chamber, or a hot air is blown to the outer periphery of the stirring and drying chamber to heat the garbage from the outside to dry the garbage. With respect to the odor generated from garbage and the like in the drying chamber, a method has been proposed in which a new deodorizer such as an ozone deodorizer is provided. However, the former method has a problem that the garbage is dried by heating the garbage from the inner wall of the stirring and drying chamber, so that the garbage drying processing efficiency is poor and the processing time is long. There is a problem that sufficient deodorization cannot be performed due to insufficient capacity or the like. In addition, a device for reducing the volume by crushing, dewatering, and bagging garbage has been proposed, but due to the presence of moisture in the garbage, there is a problem that the weight is heavy and the transportation cost is not reduced, There is a problem that garbage is easily decomposed and has an adverse effect on the environment.

In order to solve these problems, a crushing and dewatering device for crushing and dewatering garbage, a drying vessel equipped with a stirrer, a combustion device, a heat exchanger and the like are provided. The air heated by the heat exchanger is supplied into the drying container and used for drying the garbage put into the drying container, and the air containing the odor component discharged from the drying container is the air. A garbage disposal apparatus has been proposed in which odor components are heated and decomposed and exhausted by using the air as combustion air in a combustion apparatus (Japanese Patent Laid-Open No. Hei 5-13118).

Further, the duct plate 27 and the first drying chamber are blown out. A plurality of discharge plates 31 are attached to the rotating shaft 6 between the discharge plate 31 and the side plate 21.
Is brought into close contact with the surface of the duct plate 27 and is rotated in synchronization with the rotating shaft 6.

The direct drying air supplied from the direct drying air supply passage 13 passes through a passage formed between the duct plate 27 and the shielding plate 29 provided immediately before, and blows out the lower part of the duct plate 27. First drying room 8 from mouth 25
Since it is guided into the inside and is dried while being in contact with the garbage, the air is directly blown out from the direct drying air supply passage 13 connected to the upper portion of the first drying chamber 8 without disposing the duct plate 27. Appropriate and good contact with the garbage is made and its thermal efficiency is good. Since the discharge plate 31 is brought into close contact with the surface of the duct plate 27 and is rotated in synchronization with the rotating shaft 6, it is possible to prevent garbage from entering from the outlet 25, and the garbage that has entered should be discharged. The plate 31 allows the air to be discharged from the outlet 25 into the first drying chamber 8 again.

The garbage that has entered between the duct plate 27 and the shielding plate 29 is lifted by the discharge plate 31, and simultaneously lifts the water that has been initially mixed and the juice that comes out of the cells that have been destroyed by agitation or temperature rise. Shield plate 29

As shown in FIG. 3A, the discharge plate 31
Is attached to the rotating shaft 6 by using a fixture 34 also serving as a spacer for securing a space between the duct plate 27 and the shielding plate 29, whereby a direct drying air passage is secured.

In the present invention, the garbage disposal is performed by disposing the partitioning plate 23A for dividing the first drying chamber 8 and the second drying chamber 12 having an integral structure above the screw-shaped wings of the stirring and discharging means 11. There is no danger of juice leaking out of the apparatus 1A, and no garbage moves from the first drying chamber 8 to the second drying chamber 12 during stirring and drying. Further, by providing a semi-cylindrical guide plate 9A at the upper part of the stirring and discharging means 11, the fine powder of the dried garbage is discharged directly from the drying air discharge passage 14A and moves to the burner portion of the combustion device 15. It can be prevented by the cyclone effect. That is, when only the partition plate 23A is disposed, the gap formed by the screw-shaped blade of the stirring and discharging means 11 and the partition plate 23A changes depending on the rotational movement position of the screw-shaped blade, and is always large on the rotation circumference. Because of the opening, the direct drying air that has passed through the partition plate 23A may move to the direct drying air discharge passage provided in the second drying chamber 12 together with the fine garbage powder. Further, when the drying air discharge passage is provided directly in the first drying chamber 8, fine powder of garbage may be more easily accompanied and the passage may be closed by the garbage. By providing the guide plate 9A, the air for direct drying moves while rotating along the screw-shaped wings after passing through the partition plate 23A, and the fine powder of garbage conveyed simultaneously with the air is screw-shaped by inertia. Collides with the wall surface of the wing and falls and cannot directly reach the drying air discharge passage 14A, so that movement of garbage to the burner portion of the combustion device 15 can be prevented.

The rotating shafts 6A and 6B are connected at the time of use, and a plurality of L-shaped stirring rods 5 are attached to one rotating shaft 6A to form a stirring device 7 of the first drying chamber 8, and the other rotating shaft 6B is connected to the other rotating shaft 6B. A screw-shaped blade is attached to form the stirring and discharging means 11. L-shaped stirring rod 5 of first drying chamber 8 and second drying chamber 1
Stirring / discharging means 11 composed of two spiral-shaped screw-shaped blades are detachably attached to the rotating shafts 6A and 6B, respectively. That is, the L-shaped stirring rod 5 is welded and fixed to the cylindrical pipe 41A at the welding point 42A, and the cylindrical pipe 41A is attached to the rotating shaft 6A.
And is fixed with fixing bolts 43. Similarly, the stirring / discharging means 11 composed of a screw-shaped blade continuous in a spiral shape is fixed to the cylindrical pipe 41B by welding at a welding point 42B, and the cylindrical pipe 41B is inserted into the rotating shaft 6B and fixed. It is fixed with a bolt 43. 37 is a coupling for connecting the rotating shafts 6A and 6B.

And remove the stirring / discharging means 11 to remove the rotating shaft 6
B is separated from the rotating shaft 6A, the fixing bolt 43 is loosened from the rotating shaft 6A, and the stirring rods 5 are removed one after another.
Cleaning and repair can be performed easily. 43A is a screw hole for the fixing bolt 43. Conventionally, the rotating shaft 6 is constituted by one piece. When the stirring means 5 and the stirring and discharging means 11 are taken out at the time of maintenance, it is necessary to largely move the rotating shaft 6 or take out the whole. However, if the rotating shaft can be divided into two or more parts as described above, it becomes possible to remove the stirring means 5 and the stirring and discharging means 11 only by slightly moving the rotating shaft.

The means for joining the rotating shafts 6A and 6B can be considered variously and is not particularly limited. FIGS. 5A and 5B show the rotating shaft 6.
Examples of joining A and 6B are shown. FIG. 5A shows an example in which the rotating shafts 6A and 6B are joined by uneven coupling and fixed by a coupling 37. FIG. 5B shows an example in which the rotating shafts 6A and 6B are joined by semicircular cross-section and fixed by the coupling 37. As the rotating shaft increases the number of joints, the clearance causes the shaft to sag (eccentric),
The smaller the number of joints, the better.
