本考案は、高炉の炉頂部に設けれれる小ベルの取付構造
に関する。[Detailed Description of the Invention] The present invention relates to a mounting structure for a small bell provided at the top of a blast furnace.
高炉の炉頂部には、炉頂に巻上げた装入物を炉内へ適正
に装入させるために、例えば第１図に示すような、小ベ
ルａと大ベルｂとを組合せた装入装置を設けている。At the top of the blast furnace, there is a charging device that combines a small bell a and a large bell b, for example as shown in Fig. has been established.
小ベルおよび大ベルは炉心に垂下させた二重管の吊ロッ
ドに対してそれぞれ別々に連結固定され、独自に昇降作
動させて原料を段階的に落下させるようにしている。The small bell and large bell are each connected and fixed separately to a double-tube hanging rod suspended in the reactor core, and are independently raised and lowered to allow the raw materials to fall in stages.
この装入装置における小ベルの従来の取付構造は、小ベ
ル吊ロッドの円周溝に２つ割の小ベル取付金物を取付け
、その上に小べ１し・を載せて小ベルと取付金物とをボ
ルト止めする構造を用いていた。The conventional mounting structure for the small bell in this charging device is to attach a two-part small bell mounting hardware to the circumferential groove of the small bell hanging rod, place a small bell on top of it, and then attach the small bell and the mounting hardware. A structure was used in which the parts were bolted together.
しかしながら、取付金具ならびに小ベルと吊ロッドとの
間の嵌合部には、ある程度の間隙が存在するために、炉
内で発生する含塵ガスがこの間隙から小ベルの上側へ漏
洩し、このため吊ロッドがガス中のダストの影響で損傷
し、小ベル上への原料装入時、ガスの吹出しによる大気
への粉塵の公害問題や小ベルの落下事故を招くなどの不
都合があった。However, since there is a certain amount of gap between the fitting and the fitting between the small bell and the hanging rod, dust-containing gas generated in the furnace leaks from this gap to the upper side of the small bell. As a result, the hanging rods were damaged by the dust in the gas, causing inconveniences such as the problem of dust pollution caused by gas blowing out into the atmosphere and the accident of the small bell falling when charging raw materials onto the small bell.
本考案の目的は、従来の小ベル取付構造におけるこのよ
うな不都合に対処するために、安定性のある取付構造を
提供することにある。An object of the present invention is to provide a stable mounting structure in order to overcome such disadvantages in the conventional small bell mounting structure.
本考案の取付構造は、第２図および第３図に示すように
、小ベル吊ロッド（以下、吊ロッドという。As shown in FIGS. 2 and 3, the mounting structure of the present invention includes a small bell hanging rod (hereinafter referred to as a hanging rod).
）１の円周溝に２つ割の小ベル取付金物（以下、取付金
物という。) A small bell mounting hardware split into two in the circumferential groove of 1 (hereinafter referred to as the mounting hardware).
）２を嵌合し、取付金物２の上に小ベル３を載せて一体
化する構造は従来手段と同様であるが、小ベル上面の軸
心部に、吊ロッド１に密嵌するガス・シール４を嵌挿し
、さらにその上にノング・プレート５を組合せ、これら
の部材、すなわち取付金物２、小ベル３、ガス・シール
４およびリング・プレート５をボルト６によって一体に
緊結したもので゛ある。) 2 and placing the small bell 3 on the mounting hardware 2 to integrate them is the same as the conventional means. A seal 4 is inserted and a non-long plate 5 is assembled on top of the seal 4, and these members, that is, the mounting hardware 2, the small bell 3, the gas seal 4, and the ring plate 5 are tightened together with bolts 6. be.
これによって、吊ロッド１と小ベル３との間に形成され
ている間隙７は、ガス・シール４によって完全にシール
されるが、さらにリング・プレート５と吊ロッド１との
接合側を、全周囲にわたって溶接し、肉盛８を形成して
おく。As a result, the gap 7 formed between the hanging rod 1 and the small bell 3 is completely sealed by the gas seal 4, but the joining side of the ring plate 5 and the hanging rod 1 is completely sealed. Welding is performed over the periphery to form a build-up 8.
第３図に示すように、リング・ブレート５上を円周方向
に例えば、４等分する位置に、リング・プレート５と吊
ロッド１との両方に接するリブ板９を垂設し、溶接等に
よって両部材に固定しておく。As shown in FIG. 3, a rib plate 9 that contacts both the ring plate 5 and the hanging rod 1 is installed vertically at a position that divides the ring plate 5 into four equal parts in the circumferential direction, and welding etc. Fix it to both parts by.
以上の説明から明らかなように、本考案の取付構造によ
れば、ガス・シールと溶接とによる二重のガス・シール
構造であるので、従来のメタル・シール構造に比較して
著しいシールの完全化が図れる。As is clear from the above explanation, the mounting structure of the present invention has a double gas seal structure consisting of a gas seal and welding, so the seal is significantly more complete than the conventional metal seal structure. can be achieved.
また、リブ板９が小ベル３の吊金物として機能化される
ため支持面で安定性も向上する。Furthermore, since the rib plate 9 functions as a hanging hardware for the small bell 3, stability is also improved in terms of support.
