Approximately 000 mm, height is approximately 1500 to 2500
mm, and an air ejection pipe for ejecting air toward the gas discharge side is provided in the entrance of the chimney.

According to the present invention, the air outlet of the vertical air supply pipe actively supplies the outside air to the entire range from the bottom to the required height position in the combustion chamber, and the air outlet of the lower air supply pipe. Is accumulated on the bottom of the combustion chamber and actively supplies outside air to the unburned material which is hardly burned, so that the combustion of the burned material becomes efficient.

[0007] Further, relatively large incineration materials such as wood used for the loading platform of large trucks can be efficiently incinerated without the necessity of small processing. Furthermore, when air is blown from the air blow-out pipe to the inlet of the chimney, this part functions as an ejector, and the combustion gas in the combustion chamber is positively discharged, and the supply of outside air is promoted. In addition to being efficient, black smoke and the like are prevented from leaking from the gap between the incineration opening and the lower opening.

On the upper surface of the base plate 15, relatively large blowers 18, 18 are provided via a box-shaped base 17 at each of opposing positions on the diameter line of the cylindrical body 1 a outside the cylindrical body 1 a. A relatively small blower fan 19 is provided on the side of the blower fan 18. At this time, the capacity of the blower fan 18 is about 7 to ⁹ m ^3, and that of the other blower fan 19 is about 2 to ³ m ³ .

Reference numeral 20 denotes a vertical air supply pipe provided at a vertical position near the peripheral wall of the combustion chamber 1, and the blower fans 18, 18
The pipes having a diameter of about 100 to 150 mm are formed upright at two locations facing each other on the diameter line of the combustion chamber 1, and each supply pipe 20 supplies external air from the corresponding blower fan 18. It is supposed to be done.

Each of the vertical air supply pipes 20 is provided from the bottom of the combustion chamber 1 to a point exceeding the height center point and has a closed end.
A large number of air ejection holes 21 are formed at appropriate intervals, orientations, and arrangements at zero-length positions.

The air ejection holes 21 are specifically shown in FIG.
As shown in each of the vertical air supply pipes 20,
Six holes a having a diameter of 14 mm and two holes a having a diameter of 6 mm
At a specific position in the circumferential direction at approximately the same interval in the vertical direction,

Make

Reference numeral 22 denotes a lower air supply pipe provided along the vicinity of the bottom surface of the combustion chamber 1. Specifically, a pipe member having a diameter of about 30 to 65 mm having a large number of air ejection holes 23 on the peripheral surface is provided. It is directed toward the diametric direction. Reference numeral 24 denotes an air ejection pipe opened in the inlet of the chimney 2 for ejecting air into the chimney 2 toward the gas discharge side.

An example of the use of the product of the present invention configured as described above and the operation thereof will be described. By swinging the operation handle 9,
The incinerated material opening / closing port 3 is temporarily opened to incinerate the incinerated material in the combustion chamber 1.
After opening the lower opening / closing opening 10 and supplying newspaper paper or the like as fired to ignite the incinerated material, the opening / closing opening 10 is closed and the lid 11 is locked by the lock device 13, The three blowing fans 18, 18, and 19 are set to the operating state. During normal operation, the air adjustment valve 26 is in a completely closed state.

The outside air supplied from the blowing fans 18, 18, 19 is blown into the combustion chamber 1 from the vertical air supply pipes 20, 20 and the lower air supply pipe 22, so that the incinerated material keeps burning. I do. At this time, the air blown out from the vertical air supply pipe 20 tends to be blown out in the direction of the arrow f1, so that the inside of the combustion chamber 1 turns from the bottom to the top while turning in the direction of the arrow f1 at an appropriate speed. It is supplied to every corner while flowing.

Further, a large amount of air jetted from the lower air supply pipe 22 is supplied to the lowermost part, particularly the central part, of the combustion chamber 1 and flows upward together with the air supplied from the vertical air supply pipe 20. . Such a flow of air supplies sufficient oxygen for the combustion of the incineration in the combustion chamber 1 and efficiently burns it. At this time, the generated combustion gas is discharged from the chimney 2. You.

When the incinerated material in the combustion chamber 1 is properly incinerated, the incinerated material opening / closing port 3 is opened, and the next incinerated material is additionally supplied. At the time of this supply, the flame rises from the incineration material opening / closing opening 3, but the incineration material is mechanically introduced, so that the hot air does not hinder the work. In addition, when a relatively small amount of incinerated material is introduced, the incineration can be performed through the lower opening / closing port 10. In this case, the flame does not flow outward, so that it can be manually performed.

If the incineration of the incinerated material is continued as described above, unburned ash and small pieces accumulate on the bottom surface of the combustion chamber 1. Due to the active supply of air to the interior of the ash, this deposit burns completely and eventually ends up in ash with a significant reduction in volume and complete fluidity.

During combustion of the incinerated material, when air is not sufficiently supplied due to a large amount of the incinerated material in the combustion chamber 1, the air regulating valve 26 is opened to release the air from the air ejection pipe 24. They erupt. As a result, the inlet of the chimney 2 functions as an ejector, and the gas in the combustion chamber 1 is actively discharged to the outside.
Since the air pressure in the inside of the combustion chamber 1 is reduced, the supply of air from the vertical air supply pipe 20 and the lower air supply pipe 22 is promoted.
The shortage of air inside is eliminated. At this time, black smoke generated in the combustion chamber 1 due to incomplete combustion due to lack of air is prevented from leaking from the incineration material opening 3 and the lower opening 10 and quickly discharged from the chimney 2. Because

In the above embodiment, the vertical air supply pipe 2
Three or more zeros may be provided. In this case, it is preferable that these supply pipes 20 are provided in an equiangular arrangement in the circumferential direction of the combustion chamber 1.

When the product of the present invention was actually manufactured and tested, the wood (length 750) used for the bed of a large truck was
mm) were completely incinerated in about 30 minutes. In addition, rubber tires of trucks, which are generally considered to be difficult to incinerate, could be incinerated with almost no emission of smoke.

[0028]

According to the present invention constructed as described above, it is possible to supply sufficient air to the incinerated material with a simple structure, and it is used for a relatively large incinerated material, for example, a cargo bed of a large truck. In addition to being able to incinerate a relatively large amount of wood and the like quickly and quickly, it is also possible to efficiently incinerate rubber tires of trucks.

According to the second aspect of the present invention, the size of the wood used for the loading platform of the large truck is suitable for incineration, and the wood can be incinerated with little trouble.

According to the third aspect, when the amount of incinerated material in the combustion chamber is too large and the supply of air is insufficient, the inlet of the chimney is made to function as an ejector, so that the gas in the combustion chamber is reduced. Can be positively discharged to the outside, whereby the supply of air from a vertical air supply pipe or the like is promoted, and shortage of air in the combustion chamber can be quickly eliminated.
