（産業上の利用分野）
本考案は竪型多段式マツフル炉に関するもので
ある。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a vertical multi-stage Matsufuru furnace.
（従来技術とその問題点）
従来、竪型マツフル炉にあつては、マツフルは
その上端部を固定点として吊下げ方式となつてい
る。(Prior art and its problems) Conventionally, in the case of a vertical Matsufuru furnace, the Matsufuru is hung from its upper end as a fixed point.
ところで、この炉内マツフルは、その表面がバ
ーナあるいは、電熱ヒータ等の加熱手段により高
温にさらされることと、上端部を固定点として吊
下げられ、その重量が上端部にかかるため、その
板厚は、マツフル材における高温クリープ制限応
力内で、炉操業条件等により決定され、全長にわ
たつてこの決定された厚みとなつている。 By the way, the surface of Matsufuru in the furnace is exposed to high temperatures by a heating means such as a burner or an electric heater, and the upper end is suspended from a fixed point, so the weight is applied to the upper end, so the thickness of the board is limited. is determined by the furnace operating conditions, etc. within the high temperature creep limit stress of the pinewood material, and the determined thickness is maintained over the entire length.
したがつて、炉温が1150℃であれば、重量上の
制限からマツフル長さは７〜9m程度であり、生
産量の増大に対処するために、炉の大形化（加熱
帯の延長）を図るにも制限があつた。 Therefore, if the furnace temperature is 1150℃, the Matsufuru length is about 7 to 9 meters due to weight restrictions, and in order to cope with the increase in production, the furnace must be made larger (lengthening the heating zone). There were also restrictions on what could be done.
そこで、本出願人は、マツフルの板厚を上部か
ら下部にかけて小さくし、上端部にかかる重量を
実質的に減少することにより、マツフル長を長く
する技術を、特願昭60−151733号（特開昭62−
13985号）で提案した。 Therefore, the present applicant proposed a technique for increasing the length of Matsufuru by reducing the thickness of the Matsufuru from the upper part to the lower part and substantially reducing the weight applied to the upper end. 1986-
No. 13985).
しかしながら、このようにしても、20m以上の
一体構造のマツフルは最上段の板厚が厚くなると
同時に、上下方向における板厚の相違によりマツ
フル内外部の温度差が大となり、実際の使用が不
可能であつた。 However, even with this method, the thickness of the uppermost layer of Matsufuru, which has an integral structure of 20 m or more, becomes thicker, and at the same time, the temperature difference between the inside and outside of Matsufuru increases due to the difference in board thickness in the vertical direction, making it impossible to actually use it. It was hot.
本考案は前記問題点は、マツフルを一体構造と
していることに起因していることを見出した。 The present invention has found that the above-mentioned problem is caused by the integral structure of the matsufuru.
（前記問題点を解決すべき手段）
本考案は前記問題点を解決するために、竪型マ
ツフル炉において、炉殻とマツフルとで構成され

である。(Means for solving the above problems) In order to solve the above problems, the present invention provides a vertical Matsufuru furnace in which a plurality of unit furnace bodies each consisting of a furnace shell and a Matsufuru are vertically arranged in multiple stages. In addition, each matsufuru is connected by expansion joint means.

まず、接続管１１と伸縮継手１２とを取り外す
とともに、図示しないボルトを取り外して下部炉
殻４Ｂを分割炉殻４ｃと固定炉殻４ｄとに分離す
る。 First, the connecting pipe 11 and the expansion joint 12 are removed, and bolts (not shown) are removed to separate the lower furnace shell 4B into the divided furnace shell 4c and the fixed furnace shell 4d.
そして、前記台車８Ｂを図上左方に移動する。
この場合、分割炉殻４ｃと下部マツフル６Ｂとは
台車８Ｂに支持されているため、上部炉殻４Ａと
上部マツフル６Ａの存在しない位置に移動する。 Then, the cart 8B is moved to the left in the figure.
In this case, since the divided furnace shell 4c and the lower Matsufuru 6B are supported by the cart 8B, they are moved to a position where the upper furnace shell 4A and the upper Matsufuru 6A are not present.
したがつて、ここで、下部マツフル６Ｂを適宜
手段により抜き取り、修理あるいは交換すればよ
い。交換が終了すると、再度、下部マツフル６Ｂ

態に連結するものである。 Therefore, at this point, the lower matsufuru 6B may be removed by appropriate means and repaired or replaced. Once the exchange is complete, lower Matsuful 6B again.
while having the upper end supported by the trolley 8B,
Move the trolley 8B and fix the divided furnace shell 4c to the furnace shell 4d.
and connect the expansion joint means 10 to its original state.
なお、前記上部マツフル６Ａの交換も前記と同
様である。 Note that the replacement of the upper pine full 6A is also the same as described above.
また、前記説明では、２段構造のものを示した

A and 8B, but the present invention is not limited thereto, and other means of transportation may be used.
（効果）
以上の説明で明らかなように、本考案によれ
ば、炉殻とマツフルで構成される単位炉体を上下
方向に複数多段に配設し、かつ、各マツフル間を
伸縮継手手段で接続し、竪型多段式のマツフル炉
としたものであるから、各マツフルは短くてよ
く、つまり、板厚を均一にする場合でも薄くでき
るから熱応答性がよく、温度調節も容易であるば
かりでなく、マツフルの熱収縮は伸縮継手手段で
吸収できるため、全体としてマツフルコストが安
価で、長尺のマツフル炉を可能とすることができ
る。(Effects) As is clear from the above explanation, according to the present invention, a plurality of unit furnace bodies each consisting of a furnace shell and a matsufuru are arranged in multiple stages in the vertical direction, and expansion joint means are used between each matsufuru. Since it is connected to form a vertical multi-stage Matsufuru furnace, each Matsufuru can be short.In other words, even if the plate thickness is made uniform, it can be made thinner, so the thermal response is good and temperature control is easy. Instead, the thermal contraction of the Matsufuru can be absorbed by the expansion joint means, so the Matsufuru cost as a whole is low, and a long Matsufuru furnace can be made possible.
また、炉殻を、固定炉殻と炉長方向に分割した
分割炉殻との分割構造とし、この分割炉殻とマツ
フルとを炉幅方向に移動可能とすれば、冷却帯等
が存在していても、これらに影響されることなく
マツフルを移動でき、マツフルの交換を容易に行
うことができる。 In addition, if the furnace shell has a divided structure of a fixed furnace shell and a divided furnace shell divided in the furnace length direction, and the divided furnace shell and the matsufuru are movable in the furnace width direction, a cooling zone etc. can be eliminated. However, the Matsuful can be moved without being affected by these factors, and the Matsuful can be easily replaced.
しかも、マツフルと分割炉殻とを移動する移動
手段は、マツフルの炉外支持構造物として兼用す
るため、全体としての構造も簡単である。 Moreover, since the moving means for moving the Matsufuru and the divided furnace shells also serves as the support structure outside the furnace for the Matsufuru, the overall structure is simple.
さらに、伸縮継手手段に冷却装置を設ければ、
伸縮継手として金属ベローズを使用する場合でも
金属ベローズの温度を容易に調節でき、その寿命
を延ばすことができる。 Furthermore, if the expansion joint means is provided with a cooling device,
Even when a metal bellows is used as an expansion joint, the temperature of the metal bellows can be easily adjusted and its life span can be extended.
なお、バーナ等の燃焼機器を、実施例に示すよ
うに、固定炉殻側のみに設ければ、マツフルの交
換にあたつて、バーナ配管等を着脱する必要がな
く、マツフルの交換作業がそれだけ簡単になると
いう効果を奏する。 In addition, if combustion equipment such as burners is installed only on the fixed furnace shell side as shown in the example, there is no need to attach or remove the burner piping etc. when replacing the Matsufuru, and the work to replace the Matsufuru is reduced. This has the effect of making it easier.
