The outer kiln 13 has a housing shape in which the upper surface is closed and the lower surface is open, and the column 1 is supported via pulleys 16 on the side surfaces.
4 so that it can be lifted.

A balance weight 17 is provided outside the support 14.
The balance weight 17 and the outer kiln 1
3 and the chain 18 guided by the rollers 15 and 15
Are connected. The outer kiln 13 is always fixed to the base portion 12 by a clamp (not shown), and the balance weight 17 is suspended above the column 14. The size of the combustion furnace 11 is such that it can be mounted on a small truck.

The combustion section 20 is formed in a housing shape in which a plurality of bars are combined, and a plurality of bars are arranged on the bottom surface in parallel with an expander metal or at a small pitch. This combustion section 20
Is supplied with wood from waste wood as fuel. Two partition members 21 are attached to the upper surface to divide the inside into three parts.

An auxiliary burner 22 using kerosene as fuel is mounted on the side surface. This auxiliary burner 22
Burns the kerosene during an initial period in which the wood input into the combustion unit 20 is ignited and the amount of heat of combustion is small. Combustion unit 20
When the combustion becomes normal, the supply of kerosene is stopped and only air is blown.

The inner kiln 30 is placed on the combustion section 20 to produce charcoal. In this embodiment, the inner kiln 30 is used.
Three containers 31 and a lid 32 (see FIG. 4) obtained by dividing the volume of
It is composed of The container 31 has a capacity obtained by dividing the inner kiln 30 into three parts.
1 is used. The lid 32 is formed so as to block the flow of air into the container 31.

The inner kiln 30 does not necessarily need to be divided, but may be constituted by a single container having a large capacity as shown in FIG. 5 and fitted with a lid corresponding thereto. The combustion part 20 and the inner kiln 30 are drawn out of the outer kiln 13 by a forklift or the like when the outer kiln 13 is lifted.

The secondary combustion chamber 40 is provided above the outer kiln 13. A burner 41 using kerosene as fuel is provided on a side surface of the secondary combustion chamber 40. A refractory is adhered to the inner peripheral wall, but the bottom surface in contact with the combustion portion 40 is partitioned by a material having good heat conductivity such as an iron plate or a stainless steel plate. The exhaust gas passing through the inside is heated by the burner 41 and the
It is directly heated by the heat from.

Then, the exhaust gas is heated to about 800 ° C. to remove smoke and dioxin. Although not shown, the secondary combustion chamber 40 is provided with a sensor for detecting an internal temperature.

The gypsum heating chamber 50 is provided above the outer kiln 11 and adjacent to the secondary combustion chamber 40. The gypsum heating chamber 50 is heated to 200 to 450 ° C. to recycle waste gypsum generated from the dismantled house by introducing exhaust gas from the secondary combustion chamber 40. Gypsum is filled. That is, the gypsum heating chamber 50 heats the gypsum using the residual heat of the combustion part 20. In order to improve the flow of hot air, it is preferable to provide a bar inside which plate-like gypsum is stacked with a gap therebetween. The method is not particularly limited as long as the method uses residual heat. For example, a heat exchanger may be provided.

Next, the operation of the above configuration will be described.

When the clamp of the outer kiln 13 is released and the balance weight 17 is pulled down, the outer kiln 13 is pulled up (see FIG. 1). Then, the combustion part 20 and the inner kiln 30 are drawn out of the outer kiln 13 using a forklift or the like.
Here, since the combustion part 20 and the gypsum heating chamber 50 are integrally formed, they are compactly assembled and contribute to miniaturization.

Next, wood as fuel is supplied to the combustion section 20. This wood is selected from the scraps of dismantled houses. Also, wood for producing charcoal is filled in the three inner kilns 30. This wood is preferably filled to the full capacity of the inner kilns 30, and if the amount of wood is small relative to the three inner kilns 30, the number of the inner kilns 30 is reduced and each inner kiln 30 is reduced.
Is filled with wood to full capacity. The reason is that the inner kiln 30
If the amount of wood is small relative to the capacity of the wood, the supply of oxygen to the wood will increase, and the wood will burn out,
It becomes ash instead of charcoal.

The inner kiln 30 is covered with a lid 32 and the combustion section 20
, That is, between the partition members 21. Then, the inner kiln 30 and the combustion section 20 are placed on the base section 12. Then, when the balance weight 17 is lifted, the outer kiln 13 descends and covers the inner kiln 30 and the combustion unit 20. Therefore, the outer furnace 13 is fixed to the base portion 12 by being clamped.

Next, into the gypsum heating chamber 50, plate gypsum or powder gypsum in the waste material is charged. In order to improve the circulation of the hot air, it is preferable to insert them so that they have a space therebetween.

Next, when the auxiliary burner 22 is burned, the wood introduced into the burning section 20 is ignited. When the auxiliary burner 22 is burned for about 5 minutes, the combustion state of the combustion section 20 becomes a steady state. Thereafter, the supply of kerosene is stopped and only the supply of air is performed.

The wood in the inner kiln 30 is heated according to the combustion of the combustion section 20. Since the supply of air is shut off by the lid 32 inside the inner kiln 30, the wood inside becomes charcoal.

The exhaust gas from the combustion section 20 is introduced into the secondary combustion chamber 40 and heated to about 800 ° C. by the burner 41. Then, smoke is removed and dioxin is further removed. The temperature of the combustion section 20 may be detected by a sensor, and when the temperature becomes equal to or higher than a predetermined temperature, the supply of kerosene to the burner 41 may be stopped, and the combustion section 20 may be directly heated. The hot air that has passed through the secondary combustion chamber 40 is introduced into the gypsum heating chamber 50. The temperature in the gypsum heating chamber 50 is 200 to 450
Partial outside air is introduced so that the temperature becomes ° C. Then, the hot air that has passed through the gypsum heating chamber 50 is discharged to the outside.

When the exhaust gas from the gypsum heating chamber 50 has an odor, the exhaust gas from the gypsum heating chamber 50 is again introduced into the secondary combustion chamber 40 through the ventilation pipe 51 as shown in FIG. It is preferable to discharge after removing the odor.

According to the above embodiment, the following effects can be obtained. (1) Since the combustion section 20 and the gypsum heating chamber 50 are integrally formed, the combustion furnace 11 can be reduced in size, and can be moved on a truck bed, so that on-site processing is also possible. . (2) Since charcoal can be produced using wood as fuel, the fuel efficiency is improved as compared with a conventional fuel that requires fuel such as kerosene. (3) The outer kiln 13 is configured to be movable up and down, and the inner kiln 30 and the combustion unit 20 are moved outward by a forklift or the like. The work of filling wood into the kiln 30 can be performed in a wide place, and workability is significantly improved. (4) Since the secondary fuel chamber 40 is provided and the exhaust gas is heated to a high temperature, dioxin and smoke can be removed, and the environment is not polluted. (5) Since the secondary fuel chamber 40 is provided above the outer kiln 13 and is directly heated by the heat from the combustion section 20, the combustion efficiency is good. (6) Since the inner kiln 30 is divided into a plurality of pieces, it is possible to store an appropriate amount of wood for the capacity of the charcoal to be produced, and to always produce stable quality charcoal. (7) The gypsum heating chamber 50 is provided at the upper part of the outer kiln 11, and the gypsum generated from the dismantled house is heated by introducing exhaust gas into the gypsum heating chamber 50, so that the gypsum can be reused. (8) When the exhaust gas from the gypsum heating chamber 50 has an odor, the exhaust gas from the gypsum heating chamber 50 is introduced again into the secondary combustion chamber 40 through the ventilation pipe 51 and heated, so that the odor can be removed. Does not cause pollution
