Description

本発明は、貯蔵タンクのシール部材に関し、詳細には、貯蔵タンクのインナールーフと側板との隙間に設ける貯蔵タンクのシール部材に関する。   The present invention relates to a seal member for a storage tank, and more particularly to a seal member for a storage tank provided in a gap between an inner roof and a side plate of the storage tank.

貯蔵タンクの中でもインナーフロートタンクは、雨水および大気中の飽和水分における貯蔵油の品質劣化防止、臭気による環境汚染の抑制等のため、主に、石油化学製品油の貯蔵に用いられている。   Among the storage tanks, the inner float tank is mainly used for storing petrochemical oils for the purpose of preventing quality deterioration of stored oil due to rainwater and saturated moisture in the atmosphere, and suppressing environmental pollution due to odor.

当該インナーフロートタンクは、従来の円筒タンク（コーンルーフタンク、ドームルーフタンク）の内部に、改めて浮屋根を追加設置したものが主流である。   The main type of the inner float tank is that a floating roof is newly installed inside a conventional cylindrical tank (cone roof tank, dome roof tank).

従来より、インナーフロートタンクでは、側板内壁面に設けるシール部材として、主にウレタンの表面を、帯電防止用のポリテトラフルオルエチレンでラミネートしたものが使われていた。   Conventionally, in the inner float tank, as a sealing member provided on the inner wall surface of the side plate, a surface of urethane mainly laminated with antistatic polytetrafluoroethylene has been used.

また、大型浮屋根式石油貯蔵タンクのシール部材として、例えば、特許文献１に記載されているようなシール部材が知られている。   Moreover, as a sealing member of a large floating roof type oil storage tank, for example, a sealing member as described in Patent Document 1 is known.

該特許文献１には、タンク内壁面とウェザーシールド先端との隙間から貯蔵タンク内に雨水が浸入するのを確実に防止するために、複数枚の金属板を貯蔵タンクの円形状の側壁に沿って配設してウェザーシールドとし、該ウェザーシールドの基端部を、浮屋根に固定金具を介して取り付けると共に、先端を外側に折り曲げて貯蔵タンクの内壁面に摺接することが記載されている。
また、特許文献１には、ウェザーシールドの先端上方の貯蔵タンク内壁面に、ウェザーシールドの外周面と貯蔵タンクの内壁面との間隙を覆う廂状の覆い部材を設け、この廂状の覆い部材を、ウレタンフォーム等の発泡材により形成することが記載されている。
特開２００１−４８２８６号公報 In Patent Document 1, a plurality of metal plates are arranged along the circular side wall of the storage tank in order to reliably prevent rainwater from entering the storage tank from the gap between the tank inner wall surface and the weather shield tip. It is described that a weather shield is provided and a base end portion of the weather shield is attached to the floating roof via a fixing bracket, and the tip is bent outward to be in sliding contact with the inner wall surface of the storage tank.
Further, in Patent Document 1, a hook-shaped covering member that covers the gap between the outer peripheral surface of the weather shield and the inner wall surface of the storage tank is provided on the inner wall surface of the storage tank above the tip of the weather shield. Is formed of a foam material such as urethane foam.
JP 2001-48286 A

ここで、浮屋根を追加設置したものは、浮屋根式貯蔵タンクとして設置されたものでないため、側板内壁面の縦、横の溶接線の余盛りが除かれておらず、シール部材が摺動するには粗悪な状態であり、これをスムーズにするには、多大なコストが発生するため一般的には粗悪な状態のままでインナールーフを設置することが行われていた。   Here, the additional installation of the floating roof is not the one installed as a floating roof type storage tank, so the vertical and horizontal weld lines on the inner wall of the side plate are not removed, and the sealing member slides. In order to make this smooth, it takes a great deal of cost. Generally, the inner roof has been installed in a poor state.

そのため、長期間の使用による側板内壁面とインナールーフ隙間のシール部材の上下摺動により、シール部材が溶接線余盛りで破損し、本来のシール効果が保たれない場合が生じていた。   For this reason, there has been a case where the seal member is damaged due to the welding line surplus due to the vertical sliding of the seal member between the inner wall surface of the side plate and the inner roof due to long-term use, and the original sealing effect cannot be maintained.

すなわち、インナーフロートタンクのシール部材では、使用中に、表面のポリテトラフルオルエチレンが破損し、該破損部分から内部に浸入した油成分が、ウレタンを破損するので、耐久性に優れたシール効果が得られなかった。   That is, in the seal member of the inner float tank, the polytetrafluoroethylene on the surface is damaged during use, and the oil component that has entered inside from the damaged portion damages the urethane, so that the sealing effect with excellent durability is achieved. Was not obtained.

従って、本発明の解決しようとする課題は、上述の従来のシール部材の課題を解決し、耐久性に優れたシール部材を提供することにある。   Therefore, the problem to be solved by the present invention is to solve the above-mentioned problems of the conventional seal member and to provide a seal member excellent in durability.

本例では、貯蔵タンクのシール部材１を、例えば、直径が約２０ｍの貯蔵タンクのインナールーフ２と側板５との隙間に、シール受材３を用いて取り付ける場合の一例について説明する。   In this example, an example in which the seal member 1 of the storage tank is attached to the gap between the inner roof 2 and the side plate 5 of the storage tank having a diameter of about 20 m using the seal receiving material 3 will be described.

該シール部材１は、ポリテトラフルオルエチレンからなる、縦が約６０ｃｍ、横が約３０ｃｍ、厚さが約１．５ｍｍの長方形の板状物によるものであり、タンクの大きさに応じて複数枚を用意した。   The seal member 1 is made of a rectangular plate-like material made of polytetrafluoroethylene having a length of about 60 cm, a width of about 30 cm, and a thickness of about 1.5 mm. A sheet was prepared.

当該シール部材１の長手方向を、放物線状に湾曲させて折り曲げ、折曲端の反対側を重ね合わせて重合部１ａとした。   The longitudinal direction of the seal member 1 is bent in a parabolic shape and bent, and the opposite side of the bent end is overlapped to form a superposed portion 1a.

そして、シール部材１の弾性力を利用して、折曲端側を、側板５の内壁面に上向きに圧着状態で接触させつつ、重合部１ａを、インナールーフ２の外縁上面に配置し、ボルトとナットによる固定金具４でインナールーフ２に固定した。   Then, using the elastic force of the seal member 1, the overlapping portion 1 a is arranged on the outer edge upper surface of the inner roof 2 while the bent end side is brought into contact with the inner wall surface of the side plate 5 in an upwardly crimped state. And it fixed to the inner roof 2 with the fixing metal fitting 4 with a nut.

ここで、シール部材１をインナールーフ２に固定する際に、シール部材１の重合部１ａと、インナールーフ２との間に、インナールーフ２より貯蔵タンクの側板５側に突出する長さを有する板状のシール受材３を設置し、シール部材１と共に固定金具４によりインナールーフ２に固定した。   Here, when the seal member 1 is fixed to the inner roof 2, it has a length protruding from the inner roof 2 to the side plate 5 side of the storage tank between the overlapping portion 1 a of the seal member 1 and the inner roof 2. A plate-shaped seal receiving material 3 was installed and fixed to the inner roof 2 together with the seal member 1 by a fixing bracket 4.

シール受材３は、ポリテトラフルオルエチレンからなる、縦が約３０ｃｍ、横が約１９ｃｍ、厚さが約３ｍｍの長方形の板状物によるものであり、シール部材１の数と同数を用意した。   The seal receiving material 3 is made of a rectangular plate-like material made of polytetrafluoroethylene having a length of about 30 cm, a width of about 19 cm, and a thickness of about 3 mm, and the same number as the number of the seal members 1 was prepared. .

このシール受材３を用いることで、湾曲させた折曲端が、取付後も、側板５の内壁面に上向きに圧着状態で接触し続け易くなり、上向形状を保ち易くなり、シール部材１の垂れ下がり防止に有効となる。   By using this seal receiving material 3, the bent bent end can be easily kept in contact with the inner wall surface of the side plate 5 in the crimped state even after being attached, and the upward shape can be easily maintained. It is effective in preventing drooping.

また、本例に係るシール部材１を貯蔵タンク全体に取り付けるために、貯蔵タンクの大きさに応じ、複数枚のシール部材１を用いた。   Moreover, in order to attach the seal member 1 according to this example to the entire storage tank, a plurality of seal members 1 were used according to the size of the storage tank.

このように、複数のシール部材１をシール受材３と共に固定することにより、貯蔵タンクのインナールーフ２と貯蔵タンクの側板５の内壁面との隙間に、略放物線状に湾曲した複数のシール部材１が取り付けられる。   Thus, by fixing the plurality of seal members 1 together with the seal receiving material 3, the plurality of seal members curved in a substantially parabolic shape in the gap between the inner roof 2 of the storage tank and the inner wall surface of the side plate 5 of the storage tank. 1 is attached.

加えて、シール部材１を、帯電防止のために、導電性素材としてガラスクロス入ラミネート材６でラミネートすることにより、静電気による引火の危険性を回避することができる。   In addition, the risk of ignition by static electricity can be avoided by laminating the seal member 1 with a glass cloth-containing laminate material 6 as a conductive material in order to prevent electrification.
