Kaoru Fujimoto, page 65, discloses a technique of performing activation treatment using a plurality of independent kiln-type heating furnaces of a horizontal axis that are slightly inclined with respect to the horizontal line. According to this technology,
As the kiln-type first heating furnace is rotated, pre-heat treatment of the treatment objects is performed as the processed materials such as coconut shells and coal are charged from the upstream end of the furnace chamber of the first kiln-type heating furnace toward the downstream end. To proceed. Next, the processed material discharged from the downstream end of the first heating furnace is charged into the upstream end of the rotating second kiln type heating furnace, and is moved toward the downstream end of the second heating furnace of the kiln type, The carbonization of the processed material is advanced. Next, as the carbonized product discharged from the downstream end of the second heating furnace is charged into the upstream end of the rotating kiln-type third heating furnace, and is moved toward the downstream end of the third heating furnace. , The process of activating the processed product is advanced.

The use of a plurality of kiln-type heating furnaces independent of each other is because the atmospheres of the respective heating furnaces are different. When a plurality of heating furnaces independent of each other are used in this manner, the mixing of the atmospheres in the respective steps can be avoided, which is advantageous for improving the quality of the refining treatment, but increases the equipment cost.

The tempering container has a plurality of tempering containers for carrying out conditioning of the processed material in the storage chamber during transportation, and the tempering container has a shielding plate facing the inner wall surface of the furnace chamber. In the furnace chamber of the heating furnace, at least one of the heating space for heating the conditioning container and the supply and discharge of gas to and from the processed product in the accommodation chamber of the conditioning container is used to condition the processed product. It is characterized by being divided into a tempered space.

(2) The tempering container according to the present invention is used in the continuous heating furnace apparatus according to the present invention, and has a storage chamber for storing a processed material and is transported in the furnace chamber of the heating furnace. A refining container for refining a processed material in a storage chamber during transportation, the refining container has a shield plate facing an inner wall surface of the furnace chamber, and the shield plate is a furnace chamber of the heating furnace. It should be divided into a heating space for heating the tempering container and a tempering space for tempering the treated material by supplying and / or discharging gas to / from the treated material in the accommodation chamber of the tempering container. It is a feature.

(3) According to the present invention, combustion gas or high-temperature furnace gas is supplied to the heating space. As a result, the tempering container is heated, which in turn heats the processed material in the tempering container. Due to the shielding function of the shielding plate provided in the tempering container, the heating space for heating the tempering container and the supply and discharge of gas with respect to the processed material in the accommodation chamber of the tempering container are provided in the furnace chamber of the heating furnace. It is divided into a tempering space where at least one of them is performed. Therefore, due to the shielding action of the shielding plate,
The communication between the heating space and the tempering space is reduced. In other words, the shielding effect of the shielding plate enhances the shielding property between the heating space and the tempering space.

When the refining gas is supplied to the refining space communicating with the accommodating chamber of the refining container, when the material to be treated in the refining container is tempered, the heating space and the refining space are controlled by the shield plate as described above. Since the communication with the heating space is reduced, the combustion gas supplied to the heating space or the gas in the furnace of the heating space is prevented from leaking to the tempering space. As a result, it is possible to efficiently perform the refining process of the processed material in the accommodation chamber of the refining container.

Further, when the gas in the tempering space is sucked in to temper the object to be treated in the tempering container, the communication between the heating space and the tempering space becomes small due to the shielding action of the shielding plate as described above. Therefore, the combustion gas supplied to the heating space or the gas in the furnace of the heating space is suppressed from being sucked into the refining space. Therefore, the gas in the refining space can be efficiently sucked, and the refining process of the object to be treated in the accommodation chamber of the refining container can be efficiently performed.

The tempering container has a shield plate facing the inner wall surface of the furnace chamber. The shielding plate may have a form extending laterally or obliquely of the tempering container. The shielding plate divides the furnace chamber of the heating furnace into a heating space and a tempering space. The heating space is a space for heating the tempering container. The tempering space is a space for supplying and / or discharging gas to / from the processed material in the accommodation chamber of the tempering container. The shielding effect of the shielding plate reduces the communication between the heating space and the tempering space. In other words, the shielding effect of the shielding plate enhances the shielding property between the heating space and the tempering space. The heating space and the tempering space may not be communicated with each other, but there may be some gaps. In short, the communication between the heating space and the tempering space should be smaller than in the case where no shielding plate is provided. Good. In other words, the shielding property between the heating space and the refining space is high as compared with the case where the shielding plate is not provided. Generally, the shielding plate is provided on the side surface of the tempering container.

Cooling the seal portion with the seal cooling means can suppress thermal deformation of the seal portion. An air cooling method can be used as the seal cooling means, but a water cooling method may also be used. In some cases, the shield plate may be provided in the heating furnace, or the shield plate may be provided in both the tempering container and the heating furnace. The shield plate may have a form having a thermal deformation suppressing portion that suppresses thermal deformation of the shield plate. A slit and an opening can be illustrated as a thermal deformation suppression part.

A first seal portion is provided on one end side of the furnace chamber in a direction intersecting the direction in which the tempering container is conveyed, and a second seal portion is provided on the other end side thereof. A form can be adopted. Considering that the communication between the heating space and the refining space is reduced, in other words, the shielding between the heating space and the refining space is increased, the furnace chamber has a high temperature atmosphere, so It is preferable to take the expansion amount into consideration. In this case, the distance between the first sealing surface of the first sealing portion and the second sealing surface of the second sealing portion is relatively high in the furnace chamber in a high temperature region where the temperature is relatively high in the furnace chamber. It is possible to adopt a mode in which the temperature is set larger than the low temperature region where the temperature is low.

The refining container according to the present invention is a refining container that has a storage chamber for storing the processed product, and that is transferred in the furnace chamber of the heating furnace to perform the conditioning of the processed product in the storage chamber during the transfer. Thus, the tempering container has a shield plate. The shielding plate divides the furnace chamber of the heating furnace into a heating space for heating the tempering container and a tempering space facing the accommodation chamber of the tempering container. The tempering container may have a form having a container body having a containing chamber and a partition wall that partitions the containing chamber of the container body into a plurality of chambers and reinforces the container body. If the accommodation chamber of the container body is divided into a plurality of chambers in this manner, it is advantageous to suppress variations in the refining process of the processed material in the accommodation chamber of the refining container.

In the carbonization step, the processed material X in the accommodation chamber 70 of the tempering container 7 is heated and carbonized. That is, in the carbonization step shown in FIG. 4, the high-temperature furnace gas in the activation step is transferred into the gas passage 14 in the heat insulating layer 11 and is directed from the outlet 14c toward the outer wall surface of the tempering container 7 in the furnace chamber 10 by an arrow.

At this time, as described above, the inside of the furnace chamber 10 of the heating furnace 1 is divided into the heating space 100 for heating the tempering container 7 and the tempering space 150 by the shielding plate 8 of the tempering container 7. The communication between the space 100 and the refining space 150 is reduced. That is, the shielding property between the heating space 100 and the refining space 150 is high. Therefore, it is possible to prevent the combustion gas or the furnace gas supplied to the heating space 100 from leaking to the refining space 150 in the carbonization process. That is, the combustion gas or the furnace gas supplied to the heating space 100 passes through the refining space 150 and the suction port 31f.

Therefore, the activation process (conditioning process) of the processed material X in the conditioner container 7 can be efficiently performed.

In the activation step shown in FIG. 5, the second lower supply pipe 4 is
The activating gas in 3 is blown out from the outlet 43f toward the flow passage 77 of the tempering container 7 in the direction of arrow K6. The activation gas blown out from the blowout port 43f is slightly higher than the gas pressure in the furnace, so that it is suppressed from being introduced into the combustion chamber 10m side. As described above, the activating gas is blown out from the blowout port 43f in the direction of the arrow K6, so that FIG.
As can be understood from the above, the activated gas passes through the flow passage 77, and then the first hollow chamber 78 → the first through hole 73a → the second hollow chamber 79 → the second hollow chamber 79
Since the activating gas is also supplied to the inside of the storage chamber 70 of the tempering container 7 from the opening 74a to the inside of the storage chamber 70, the tempering container 7

Then, the cooling air is blown from the outlet 18 of the cooling passage 19 in the direction of the arrow K8 toward the outer wall surface of the tempering container 7, and the processing object X in the tempering container 7 is cooled. Further, in the cooling step shown in FIG. 6, the cooling air supplied by the cooling fan (not shown) also flows through the third lower supply pipe 45, and
From the outlet 45f of the lower supply pipe 45 to the flow passage 7 of the tempering container 7
It is blown toward 7 in the direction of arrow K9. Therefore, as can be understood from FIG. 10, the cooling air passes through the flow passage 77, and then the first hollow chamber 78 → the first through hole 73a → the second hollow chamber 79 → the second hollow chamber 79
Since the cooling air is introduced into the inside of the storage chamber 70 of the tempering container 7, the temperature of the tempering container 7 is increased.
