Each driving unit is activated by each of the driving devices M1 and M2, and the water supply pump is operated to circulate water in the shafts 24 and 31. Further, the inside of the combustion chamber 10 is heated by the waste oil burner 19, so that the carbonization drum 20 is sufficiently heated. The chicken manure put in the hopper 61 is loosened while being returned to the rear portion by the rotary blades 66, and is sent to the combustion device S1 side by the transfer conveyor 62. At the same time, excess chicken manure sent to the discharge side of the hopper 61 is returned by the return screw 67 to the hopper 61.
It is returned to the rear part so that it does not easily harden on the discharge side.
Also, the chicken dung returned by the rotary blades 66 and the return screw 67 is made hard to set at the rear part of the hopper 61 by the action of the inclined plate 68. It should be noted that chicken dung is hard to be solidified and does not easily collapse when it is laminated with a slightly viscous material, so originally it is easy to make it hollow, but according to this embodiment, it can always be made to collapse by the rotary blades 66, so it does not become hollow and the chicken dung is stable. Then supplied. The chicken manure passes through the conveyor bearing 63 and is introduced into the inside of the carbonized drum 20 which is heated and rotating. Carbonization drum 20
Since the inside is in an almost oxygen-free state during operation, chicken manure is gradually carbonized while being conveyed by the agitating and conveying machine 23. At this time, a large amount of combustible gas is generated together with the steam, and these are discharged into the combustion chamber 10 through the discharge holes 29 of the carbonization drum 20. The combustible gas is ignited and burned by the heat of the combustion chamber 10 at the same time as being discharged.

Carbides that have been carbonized inside the carbonization drum 20 are conveyed and fall from the discharge holes 29 to the bottom of the combustion chamber 10. Air is sufficiently introduced into the interior of the combustion chamber 10 from the primary air introducing portion 35 and the secondary air introducing portion 36. The primary air introduced from the primary air introduction unit 35 is introduced while blowing up the carbide conveyed by the agitating and conveying machine 30 with the wind pressure, so the carbide is burned with high efficiency. Waste oil burner 19
Is equipped with an exhaust gas temperature sensor, which stops if sufficient combustion is performed, and operates when the exhaust temperature falls to assist combustion. The agitating and conveying machine 30 of the combustion section 3 is designed to be capable of intermittent operation. For example, when the amount of carbide is too large, the amount of combustion is reduced by intermittent operation so that incomplete combustion due to lack of oxygen does not occur. .. Furthermore, since the shafts 24 and 31 of the agitating and conveying machines 23 and 30 rotate while being water-cooled, bending due to heat and own weight (10) is less likely to occur, and stable operation is achieved. The carbide is burned to burned ash, enters the discharge conveyor 5 through the discharge port 18, and is discharged to the outside. As described above, according to the present embodiment, first, the chicken dung is heated in a substantially oxygen-free state to be carbonized to generate a combustible gas accompanied by a foul odor, and this is burned, and further, the carbide is further heated in a sufficient aerobic state. Since it is burnt in, bad odor does not leak to the outside, and almost complete incineration can be performed with high efficiency. The present invention is not limited to the illustrated embodiments, and various modifications can be made within the scope of the claims.

[0013]

The present invention having the above-mentioned structure has the following effects. (A) According to the incinerator of the present invention, a combustible gas is heated in an almost oxygen-free state to be carbonized to generate a combustible gas accompanied by a foul odor, and the combustible gas is burned. Since it burns with sufficient heat power, no bad odor leaks to the outside and almost complete incineration can be performed with high efficiency. (B) According to the combustion device in which the heating in the carbonization process is performed by the heat generated in the combustion process, unlike the conventional device that burns and reburns fuel separately to deodorize, Since it can be effectively used, the processing cost is low. (C) According to the combustion device in which the shaft of the carbonization device and the shaft of the stirring conveyer of the combustion section are water-cooled, bending due to heat and own weight (10) is difficult to occur in combination with rotation of the shaft, and stable operation is achieved. .. (D) According to the feeding device provided with the collapsing device in the hopper,
For example, if it is a little sticky layer like chicken manure, it is hard to harden and collapse, and even a combustible material that is likely to be hollowed in the lower part of the hopper can be constantly collapsed, so that it can be stably fed to the combustion device.
