Description
【０００１】[0001]
本考案は、水平室炉式コークス炉のドア・シール装置に関するものである。 The present invention relates to a door sealing device for a horizontal chamber coke oven.
【０００２】[0002]
一般に、水平室炉式コークス炉では、シール機構を有するドアを炭化室のフレ ームに押接することにより、炭化室内の気密を保持している。そのシール機構と しては、その一例が特開昭56−70087 号公報に示されているように厚さ１mm程度 の鋼板とシール条片とによるものを使用している。 Generally, in a horizontal chamber type coke oven, the airtightness inside the carbonization chamber is maintained by pressing a door having a sealing mechanism against the frame of the carbonization chamber. As an example of the sealing mechanism, as shown in Japanese Unexamined Patent Publication No. 56-70087, a mechanism using a steel plate having a thickness of about 1 mm and a sealing strip is used.
【０００３】[0003]
このように、従来の方式は、ドアの取付・取外しの方向に、シール条片を押し 付けるものであった。しかるに、ドア及びドアフレームは、熱によりその表面プ ロフィルが不規則に変化している。したがって、図５に示すようにドアの取付・ 取外し時に、シール条片10が局部的にドアフレーム２に当たったり、しゅう動し たりして、キズ（ミゾ）11が形成され、このため、シール性が悪化するという問 題があった。 In this way, the conventional method is to press the seal strip in the direction of attaching and detaching the door. However, the surface profile of doors and door frames changes irregularly due to heat. Therefore, as shown in FIG. 5, when the door is attached / detached, the seal strip 10 locally abuts on or slides on the door frame 2 to form a scratch (groove) 11. Therefore, the seal 11 is formed. There was a problem that sex deteriorates.
【０００４】 本考案は、前記問題点を基本的に解決した、コークス炉のドア・シール装置を 提供することを目的とするものである。An object of the present invention is to provide a coke oven door sealing device that basically solves the above problems.
【０００５】[0005]
本考案は、水平室炉式コークス炉において、ドアフレーム２前面の開口部全周 にナイフエッジ３を設立し、ナイフエッジ３を挟み込むように配設した、内部に 圧空等を充填可能な可撓管４、４′を可撓管受け５、５′を介してドア本体１に 張出したブラケット６に固定し、内周の可撓管受け５′にダイヤフラム７の外周 を気密接合し、更に、可撓管内の圧力を制御する手段を具備したことを特徴とす るコークス炉のドア・シール装置である。 The present invention is a horizontal chamber furnace type coke oven, in which a knife edge 3 is established around the opening of the front surface of the door frame 2 and the knife edge 3 is sandwiched between the knife edge 3 and the inside thereof. The pipes 4 and 4'are fixed to the bracket 6 which is extended to the door body 1 through the flexible pipe receivers 5 and 5 ', and the outer periphery of the diaphragm 7 is airtightly joined to the flexible pipe receiver 5'on the inner periphery. A coke oven door sealing device comprising means for controlling the pressure in a flexible tube.
【０００６】[0006]
本考案は、前述したようにドアフレーム２前面の開口部全周にナイフエッジ３ を設立し、内部に圧空等を充填できうる可撓管２本で該ナイフエッジを挟み込む ようにしたので、従来の方式のようにシール条片をドアフレームに押付ける必要 がなく、従来の問題点、すなわち、シール条片が局部的にドアフレームに当たっ たりしゅう動したりして、キズ（ミゾ）が形成されるということが基本的に解消 した。 According to the present invention, as described above, the knife edge 3 is established around the entire opening of the front surface of the door frame 2 and the knife edge is sandwiched by two flexible tubes capable of filling compressed air inside. There is no need to press the seal strip against the door frame as in the method of No. 1, but the conventional problem is that the seal strip locally hits the door frame or slides to form scratches (grooves). It was basically solved.
【０００７】 次に、本考案を実施例に基づいてより詳細に説明する。Next, the present invention will be described in more detail based on embodiments.

図１は本考案の一実施例を示す局部平断面図、図２はその斜視図であり、図３ は本考案装置の操作説明図である。 ドアフレーム２の全周にナイフエッジ３を取付ける。ナイフエッジ３は、取外 し可能なようにボルト取付け等が好ましい。このナイフエッジを挟み込むように 配置された可撓管４、４′を、それぞれ可撓管受け５、５′を介して、ドア本体 １に取付けたブラケット６に固定する。可撓管４、４′は圧空やスチーム、Ｎ2 ガスなどの気体やあるいは各種液体を所定の圧力をかけて使用する。すなわち、 図３に示すごとく、ドアの取外し、取付け時は、可撓管４、４′内を負圧とする ことにより、可撓管の径を縮小させ、取付完了時には、正圧をかけて可撓管の径 をふくらませることによりナイフエッジに密着させるものである。このための圧 力制御手段および配管フローは、略したが、押出機のドア着脱装置と一体的に設 けることができる。また、ドアーの取付け、外し時に、例えば図４に示すように ガイド12、ガイドアーム12′およびガイドアーム12′の受け面12″等からなるガ イドを利用してスムーズに行うことは望ましい。FIG. 1 is a partially sectional plan view showing an embodiment of the present invention, FIG. 2 is a perspective view thereof, and FIG. 3 is an operation explanatory view of the device of the present invention. Attach knife edge 3 to the entire circumference of door frame 2. The knife edge 3 is preferably bolted so that it can be removed. The flexible tubes 4 and 4'arranged so as to sandwich the knife edge are fixed to the bracket 6 attached to the door body 1 via the flexible tube receivers 5 and 5 ', respectively. The flexible tubes 4 and 4'use a compressed air, a gas such as steam or N 2 gas, or various liquids while applying a predetermined pressure. That is, as shown in FIG. 3, when the door is removed and installed, the inside of the flexible tubes 4 and 4'has a negative pressure to reduce the diameter of the flexible tubes, and when the installation is completed, a positive pressure is applied. The diameter of the flexible tube is inflated so that it will be in close contact with the knife edge. Although the pressure control means and the piping flow for this purpose are omitted, they can be integrated with the door attachment / detachment device of the extruder. Further, when the door is attached and detached, it is desirable to use a guide 12, a guide arm 12 'and a receiving surface 12 "of the guide arm 12' as shown in FIG.
【０００９】 因みに、炭化室の幅 0.5ｍ×高さ 6.1ｍのコークス炉に於いて、外周管、内周 管となる0.07mm×４層のステンレス鋼製の可撓管（自由径φ75mm）を80mmはなし て配設し、圧空にて−0.02kgf/cm2 、＋0.65kgf/cm2 （いずれもゲージ圧）でド アの取付け・外しを行った。 負圧時２本の可撓管は38mmのスキ間があり、ドアの取付け・外しは極めてスム ーズに行うことができた。また正圧時には可撓管表面がつぶれてナイフエッジと 接触する幅はおおむね46mmになっており、十分なシール性があることがわかった 。By the way, in a coke oven having a width of 0.5 m in the carbonization chamber and a height of 6.1 m, a flexible tube made of stainless steel (free diameter φ75 mm) of 0.07 mm × 4 layers as an outer peripheral tube and an inner peripheral tube is used. It was installed without 80mm, and the door was attached / detached in compressed air at -0.02kgf / cm 2 and + 0.65kgf / cm 2 (both gauge pressure). At the time of negative pressure, there was a gap of 38 mm between the two flexible tubes, and it was possible to install and remove the door extremely smoothly. In addition, the width of the flexible tube surface that crushed under positive pressure and contacted with the knife edge was approximately 46 mm, indicating that there was sufficient sealing performance.
【００１０】 本実施例では、可撓管にうすい金属の積層板を用いたが、これに限ることはな く、耐熱性を有するものであれば良い。In this embodiment, a thin metal laminated plate is used for the flexible tube, but the flexible tube is not limited to this and may be any one having heat resistance.
【００１１】[0011]
本考案では、ドアフレームから独立したナイフエッジを可撓管で挟み込むよう にしたから、ドアの取付け・外し時にシール部が接触したり、しゅう動したりす ることがなくなり、キズが全く形成されなくなった。 また、ドアの裝入方向の変形がシール性に与える影響は皆無となり、その横方 向の変形についても２つの可撓管を有しているため、極めて大きな追従性が得ら れるようになった。 In the present invention, since the knife edge, which is independent from the door frame, is sandwiched by the flexible tubes, the seal part does not come into contact or slide when the door is installed or removed, and scratches are not formed at all. It was Also, the deformation of the door in the insertion direction has no effect on the sealing performance, and the lateral deformation of the door has two flexible tubes, so that extremely large followability can be obtained. It was
