It comprises a bracket 11, an opening / closing lever 12, a rod 21, a hook 27, and a spring 29. The bracket 11 is fixed to the outside of the seal bang 7 corresponding to the engaging portion 10. The opening / closing lever 12 includes a U-shaped lever main body 13 and a handle 14 provided at a bent portion thereof, and an end portion of the lever main body 13 is supported by support plates 15 and 15 provided on the bracket 11. It is rotatably supported along a plane perpendicular to the furnace shell 1 via lever support shafts 16 and 16. Further, the lever body 13 is provided with through holes 17 and 17, and the safety pin 20 is inserted through the through holes 17 and 17 and the through holes 19 and 19 of the pin support member 18 provided on the bracket 11 to open and close. The lever 12 can be fixed in the closed state (state shown in FIG. 1). The rod 21 is supported by a rod support shaft 24 provided on the lever main body 13 via a collar 22 that is mounted on one end of the rod 21 and a bearing 23 that is connected to the collar 22, and is the same as the opening / closing lever 12.

The hook 27 is made of a rectangular frame, and a through hole 28 is formed in one piece of the frame toward the center of the frame, and the rod 21 is inserted into the through hole 28. The spring 29 is mounted on the portion of the hook 27 located inside the frame, and is prevented from coming off by a nut 26 screwed into the threaded portion 25 at the end of the rod.
【００１０】 前記蓋５で開口部２を閉鎖する場合、前記蓋５を炉殻１の開口部２に配置し、 シールパッキン８をシール押さえ部材４に当接し、図３において一点鎖線で示す 開状態にある複数のパッキン圧着装置９のロッド２１を矢印ｃ方向に回転し、フ ック２７を係合部１０にそれぞれ係合する。次に、開閉レバー１２を矢印ａ方向 に回転し、安全ピン２０を貫通孔１７，１７，，１９，１９に挿通して開閉レバ ー１２を固定する。このとき、ロッド２１はレバー支持軸１６と異なる位置に設 けたロッド支持軸２４に支持されているので、開閉レバー１２の矢印ａ方向への 回転により、ロッド２１は炉殻１から後退する方向（矢印ｂ方向）に移動する。 また、ロッド２１の移動によりナット２６とフック２７に挟まれてスプリング２ ９が縮み、フック２７の係合部１０に対する係合力（圧接力）が増すと共に、シ ールパッキン８がパッキン押さえ部材４に押さえ付けられ、それらの接触部にお けるシールが確保される。When closing the opening 2 with the lid 5, the lid 5 is placed in the opening 2 of the furnace shell 1, the seal packing 8 is brought into contact with the seal pressing member 4, and the opening is shown by a chain line in FIG. The rods 21 of the plurality of packing crimping devices 9 in the state are rotated in the direction of arrow c to engage the hooks 27 with the engaging portions 10, respectively. Next, the opening / closing lever 12 is rotated in the direction of arrow a, and the safety pin 20 is inserted into the through holes 17, 17, 19, 19, and the opening / closing lever 12 is fixed. At this time, since the rod 21 is supported by the rod support shaft 24 provided at a position different from the lever support shaft 16, the rod 21 is retracted from the furnace shell 1 by the rotation of the opening / closing lever 12 in the arrow a direction ( Move in the direction of arrow b). Further, the movement of the rod 21 causes the spring 29 to be contracted by being sandwiched between the nut 26 and the hook 27, so that the engaging force (pressure contact force) of the hook 27 with respect to the engaging portion 10 is increased and the seal packing 8 is pressed against the packing pressing member 4. Affixed, ensuring a seal at their contact.
【００１１】 蓋５を外して開口部２を開放する場合、図３に示すように、安全ピン２０を外 し、開閉レバー１２を矢印ａ’方向に回転する。これにより、ロッド２１が炉殻 １に接近する方向（矢印ｂ’方向）に移動してスプリング２９が伸び、フック２ ７の係合部１０に対する係合力が弱くなる。そして、開閉レバー１２を図３に示 す一点鎖線の位置まで移動させると、スプリング２９が非伸縮状態に復帰し、フ ック２７の係合部１０に対する係合力が消滅すると共に、シールパッキン８のパ ッキン押さえ部材４に対する圧着力も消滅する。したがって、その後は、ロッド ２１およびフック２７を矢印ｃ’方向に回転することによりフック２７が係合部 １０から外れ、蓋５を開口部２から外すことができる。When the lid 5 is removed to open the opening 2, as shown in FIG. 3, the safety pin 20 is removed and the opening / closing lever 12 is rotated in the arrow a'direction. As a result, the rod 21 moves in the direction approaching the furnace shell 1 (direction of arrow b '), the spring 29 extends, and the engaging force of the hook 27 with respect to the engaging portion 10 becomes weak. When the opening / closing lever 12 is moved to the position indicated by the alternate long and short dash line in FIG. 3, the spring 29 returns to the non-expandable state, the engaging force of the hook 27 with respect to the engaging portion 10 disappears, and the seal packing 8 The pressure force applied to the packing pressing member 4 is also eliminated. Therefore, thereafter, by rotating the rod 21 and the hook 27 in the direction of the arrow c ', the hook 27 is disengaged from the engaging portion 10, and the lid 5 can be disengaged from the opening 2.
【００１２】 前記シールパッキン８が経時変化してパッキン押さえ部材４との接触部におけ るばね定数が低下した場合、ナット２６を回転してロッド基部側に移動する。こ れにより、開閉レバー１２が閉状態におけるパッキン押さえ部材４のシールパッ キン８に対する食い込み量が増し、必要なシール性が確保できる。When the seal packing 8 changes with time and the spring constant at the contact portion with the packing pressing member 4 decreases, the nut 26 is rotated to move to the rod base side. As a result, the bite amount of the packing pressing member 4 with respect to the seal packing 8 when the opening / closing lever 12 is closed increases, and the necessary sealing performance can be secured.
【００１３】 前記パッキン圧着装置９は、例えば、前記蓋５が長方形のものであれば、少な くとも対向する２辺、好ましくは４辺、にそれぞれ少なくとも１個設けるように する。また、蓋５が円形の場合、少なくとも対称に２個、好ましくは等間隔に４ 個設ける。For example, if the lid 5 has a rectangular shape, at least one packing crimping device 9 is provided on each of at least two opposite sides, preferably four sides. When the lid 5 has a circular shape, at least two symmetrically provided, preferably four equally spaced.
【００１４】[0014]
以上の説明で明らかなように、本考案にかかる炉開口部シール装置では、パッ キン圧着装置は、ボルトに比べてより少ない数で足り、しかも開閉レバーの回動 操作によって容易に蓋を着脱することができるので、蓋の開閉作業が極めて簡単 容易になる。また、経時変化によってシールパッキンの弾性が低下した場合、ば ね手段の付勢力を調整することにより、シールパッキンとパッキン押さえ部材と の圧接力を一定に維持することができ、常に安定したシール性が得られると共に 、シールパッキンの耐用寿命が延びる。 As is apparent from the above description, in the furnace opening sealing device according to the present invention, the packing crimping device requires a smaller number than the bolts, and the lid can be easily attached / detached by the turning operation of the opening / closing lever. This makes it extremely easy and easy to open and close the lid. Also, if the elasticity of the seal packing deteriorates over time, by adjusting the biasing force of the spring means, it is possible to maintain a constant pressure contact force between the seal packing and the packing pressing member, and to ensure a stable sealing performance. And the service life of the seal packing is extended.
