DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carbonization apparatus for converting wood, such as root extraction material, logging material, driftwood, etc., generated in a land to be developed into charcoal.

[0002]

2. Description of the Related Art A large amount of root extraction, logging, driftwood, and other timber are generated in construction works performed in various development projects such as dam construction projects. Trunks having a diameter of about 5 cm or more among these woods can be sold as valuables or effectively used inside and outside the construction site.

[0003] However, other trunks, root extraction materials and branches and leaves have not been found to have any particular effective use, and have conventionally been simply incinerated at construction sites and the like. This incineration is generally called open burning. However, since a large amount of smoke and residual ash is generated, it is becoming impossible to perform anything other than minor incineration in consideration of preservation of the living environment. Disposal of such root materials and foliage has been reclaimed as business-related general waste at public disposal sites.

[0004] However, due to an increase in the amount of general waste other than wood and the limitations of the capacity of disposal sites and treatment facilities, it is becoming impossible to dispose of unnecessary wood as general waste. That is the fact.

Therefore, unlike the conventional open burning, carbonization of wood such as root extraction material and logging material to reduce the volume is performed while taking out a large amount of smoke and residual ash in consideration of preservation of living environment and the like. It is possible. In this way, it is easy to dispose of root extraction material, logging material, and the like, and the obtained charcoal can be used as a soil improvement material or a water purification material in a sludge tank.

[0006]

However, in the construction work, it is difficult to sufficiently carbonize a large amount of root extraction material, which is said to be out of about 600 pieces per ha, with a conventional carbonization apparatus.

The present invention has been made in view of the above-mentioned circumstances, and in consideration of the preservation of living environment and the like, a large amount of wood, such as a root extraction material, which is produced in a large amount of construction work is carbonized for effective use. In addition, it is an object of the present invention to provide a carbonization device that can reduce the volume of wood and facilitate disposal.

[0008]

In order to achieve the above object, a carbonizing apparatus according to the first aspect of the present invention is provided with a carbonizing chamber for accommodating wood and carbonizing, and discharging smoke generated from the carbonizing chamber to the outside. A chimney is provided, and an input port for inputting the wood is provided at an upper part of the carbonization chamber, and an opening / closing lid that seals the input port is provided at the input port, and between the carbonization chamber and the chimney. Is characterized in that two adjusting plates for adjusting the flow of air to the closed carbonization chamber are provided vertically.

The carbonizing device according to a second aspect of the present invention is the carbonizing device according to the first aspect, wherein a plurality of shaped steel members having a U-shaped cross section are combined with each other on the inner wall surface of the carbonizing chamber. A heat-resistant wall filled with a heat insulating material made of fibrous material is disposed in the space of the shaped steel.

The carbonizing device according to a third aspect is characterized in that, in the carbonizing device according to the second aspect, the heat-resistant wall is attached to and detached from the inner wall surface of the carbonizing chamber by attaching and detaching means.

[0011]

According to the first aspect of the present invention, the carbonization apparatus includes a carbonization chamber for accommodating and carbonizing wood and a chimney for discharging smoke generated from the carbonization chamber to the outside. An input port for inputting the wood is provided, and an opening / closing lid for closing the input port is provided at the input port, so that the carbonization chamber in which the logging material such as root extraction is stored can be sealed. And, between the carbonization chamber and the chimney, there are provided two vertically-adjusted adjusting plates for regulating the flow of air to the closed carbonization chamber. Even in this case, sufficient carbonization can be achieved by adjusting the opening of the two adjustment plates disposed in the up-down direction.

[0012] According to the carbonizing apparatus of the second aspect, in the carbonizing apparatus of the first aspect, a plurality of shaped steel members having a U-shaped cross section are combined in a square shape on the inner wall surface of the carbonizing chamber. Since the heat-resistant walls filled with the heat insulating material made of fibrous material are arranged in the space of these shaped steel, the weight of the heat-resistant walls is lighter than that of the conventional carbonization equipment, and other construction works Transfer to the site is easy.

Further, in the carbonizing device according to the third aspect, the heat-resistant wall is configured to be attached to and detached from the inner wall surface of the carbonizing chamber by attaching and detaching means. If the performance of the heat-resistant wall deteriorates due to the heat in the carbonization chamber during use, the heat-resistant wall itself can be replaced.
