動層炉が知られている。Prior Art As shown in FIGS. 3 and 4, a cylindrical furnace body 1
A heat insulating material 2 is provided on the inner wall of the retort 4, and a retort 4 having a cylindrical shape and a dispersion plate 3 at the bottom is inserted in the center to form a heating chamber 5 around its outer periphery, and the lower part of the retort 4 is connected to an air supply pipe 6. and the upper opening 7 is opened to the upper opening 8 of the furnace body 1, and the upper opening 8 is opened to the upper opening 8 of the furnace body 1.
The furnace cover 9 can be opened and closed freely, and a jig 11 for hanging processed products having a large number of slit-like recesses 10 radially arranged on the inner surface of the upper part of the retort 4 is fixed via upper and lower reinforcing plates 12 and 13 to hold the elongated object 14. A fluidized bed furnace is known in which the upper flange 15 of the elongated object 14 is engaged with the slit-like recess 10 and suspended.

１１に複数の支柱１６を固着し、この支柱１６を
分散板３上に載置して処理品吊下げ用治具１１を
レトルト４内に支持するようにした流動層炉が知
られている。 In addition, as shown in FIG. 5, a plurality of supports 16 are fixed to the jig 11 for hanging processed products, and the supports 16 are placed on the dispersion plate 3, and the jig 11 for hanging processed products is attached to the retort 4. Fluidized bed furnaces are known.
また、第６図に示すようにレトルト４の上部に
外向フランジ１７を設け、このフランジ１７を炉
本体１の支柱１８に載置してレトルト４を炉本体
１内に吊下げ支持するようにした流動層炉が知ら
れている。 Further, as shown in FIG. 6, an outward flange 17 is provided on the upper part of the retort 4, and this flange 17 is mounted on a support 18 of the furnace body 1, so that the retort 4 is suspended and supported within the furnace body 1. Fluidized bed furnaces are known.
このような流動層炉であれば長尺物１４を吊り
下げて支持できるから長尺物１４を熱処理する際
に歪が発生することを防止できる。 Since such a fluidized bed furnace can suspend and support the elongated object 14, distortion can be prevented from occurring when the elongated object 14 is heat treated.
考案が解決しようとする問題点
第１・第２の流動層炉であると長尺物１４を熱
処理する際にレトルト４あるいは支柱１６が熱膨
張して処理品吊下げ用治具１１の位置が上下方向
に変化するので、炉蓋９を外して上部開口８より
自動搬送機の把持部を挿入して長尺物１４の上部
把持部１４ａを把持する際にその位置が上下に変
化するので、把持部の挿入ストロークが一定であ
ると把持できないことがある。Problems to be Solved by the Invention In the first and second fluidized bed furnaces, when heat treating a long object 14, the retort 4 or the support 16 thermally expands, causing the position of the object suspension jig 11 to change. Since the position changes in the vertical direction, when the furnace lid 9 is removed and the gripping part of the automatic conveyance machine is inserted through the upper opening 8 to grip the upper gripping part 14a of the long object 14, its position changes in the vertical direction. If the insertion stroke of the gripping portion is constant, gripping may not be possible.
また、第１の流動層炉であると処理品吊下げ用
治具１１がレトルト４に固着してあるので、長尺
物１４の自重がレトルト４に全て作用して変形し
易くなる。この変形を防止するためにレトルト４
の強度を向上すると重量が増加してコストアツプ
となるうえ熱容量も大きくなつてランニングコス
トも増える。 Furthermore, in the case of the first fluidized bed furnace, the jig 11 for hanging the processed product is fixed to the retort 4, so that the entire weight of the long object 14 acts on the retort 4, making it easy to deform. To prevent this deformation, retort 4
If the strength is improved, the weight will increase, which will increase the cost, and the heat capacity will also increase, which will increase the running cost.
また、第２の流動層炉であると支柱１６がレト
ルト４内に入るのでそれだけレトルト４内の容量
が減少して有効ゾーンが減少する。 Further, in the case of the second fluidized bed furnace, the support column 16 is placed inside the retort 4, so the capacity inside the retort 4 is reduced accordingly, and the effective zone is reduced.
第３の流動層炉であるとレトルト４が下方に延
びるから処理品吊下げ用治具１１があまり上下動
しないが、レトルト４自重とレトルト４内に充填
したアルミナの重量をすべて上部で支持するので
レトルト４及び炉本体１をかなり強固に作製せね
ばならずコストが高いものとなる。 In the case of the third fluidized bed furnace, the retort 4 extends downward, so the jig 11 for hanging the processed product does not move up and down very much, but the weight of the retort 4 itself and the weight of the alumina filled in the retort 4 are all supported at the top. Therefore, the retort 4 and the furnace body 1 must be made quite strong, resulting in high costs.

るようにしたものである。Means and action for solving the problem The retort is constructed by connecting a lower retort supported at the lower part of the furnace body and an upper retort supported at the upper part of the furnace body in a flexible and airtight manner. The jig for hanging processed products provided in the upper retort does not move up and down even when thermally expanded, and the retort can be supported by the upper and lower parts of the furnace body.

The upper retort 21 is placed on and connected to the support column 18 via the outward flange 17 for support, and the jig 11 for hanging the processed product is attached to the upper retort 21, and the upper part of the lower retort 20 and the lower part of the upper retort 21 are connected to each other. are telescopically and airtightly connected via a retractable sealing material 22 and a bellows 23.

でかつ気密保持して連結する。 Further, as shown in FIG. 2, the upper part of the lower retort 20 is expanded into a funnel shape, and the elastic sealing material 22 is pressed between the funnel-shaped part 20a and the lower cylindrical part 21a of the upper retort 21. The two are connected in a flexible and airtight manner.
２４はシール材２２の受け片である。 24 is a receiving piece for the sealing material 22.
考案の効果
下部レトルト２０と上部レトルト２１とが伸縮
自在でかつ気密保持して連結してあるから、レト
ルト４の熱膨張はその連結部で吸収できて上部レ
トルト２１に設けた処理品吊下げ用治具１１が上
下に変位しないので、長尺物の上部把持部の位置
が常に一定となつて自動搬送機の把持部で上部把
持部を確実に把持できて長尺物の搬入・搬出が容
易となる。Effects of the invention: Since the lower retort 20 and the upper retort 21 are telescopically and airtightly connected, the thermal expansion of the retort 4 can be absorbed by the connecting part, and the upper retort 21 can be used for hanging processed products. Since the jig 11 does not move up and down, the position of the upper grip part of the long object is always constant, and the upper grip part can be reliably gripped by the grip part of the automatic conveyance machine, making it easy to carry in and take out the long object. becomes.
下部レトルト２０が炉本体１の下部で支持さ
れ、上部レトルト２１が炉本体１の上部で支持さ
れるから、炉本体１の上・下でレトルト４を支持
できて炉本体１やレトルト４の強度を増すことな
しに確実に支持できると共に、レトルト４内には
何ら特別な支持部材が挿入されないから有効ゾー
ンが減じることがない。 Since the lower retort 20 is supported at the lower part of the furnace body 1 and the upper retort 21 is supported at the upper part of the furnace body 1, the retort 4 can be supported above and below the furnace body 1, thereby increasing the strength of the furnace body 1 and the retort 4. The retort 4 can be reliably supported without increasing its capacity, and since no special support member is inserted into the retort 4, the effective zone will not be reduced.
