Description
【発明の詳細な説明】 複数個のセグメントより成る押し出し装置 この発明は、ハウジング内で、ネジ込みボルトで固定された個々のセグメント より成る少なくとも1基の回転可能な押し出し軸により、生成物を熱的、機械的 、化学的、および/または物理的処理を行う装置に関し、前記ボルトは前記セグ メント内の穿腔に内挿され、螺旋状空腔内に内装され、押し出し軸外装表面は螺 旋状ひだによって包囲されたものである。 この種の押し出し軸は、産業上各種の分野で使用され、通常電動機または変速 機構には、セグメント内の縦方向空腔内に形成された楔状凹部に内装された楔軸 が連結されている。特にこの場合、螺旋状ひだで包囲された押し出し軸が主体で あり、この押し出し軸によって、生成物が熱的、機械的、化学的、および/また は物理的処理を受ける。つまり楔軸の把持によって捕捉される捻り応力が、各セ グメントに作用することを意味する。 この種の装置は、例えばスイス特許第CH−PS674474号、および国際 特許出願番号PCT/CH83/0059号明細書に開示されており、生成物は 、2個の相互作用する押し出し軸によって、機械的に閉鎖され、特に繊維化され 、熱的に処理される。 特に楔軸の凹腔付近で発錆し易く、液体の生成物の場合にセグメントの取り外 し困難で、特に付け換えが困難であるという 欠点がある。 特に楔軸が螺旋状ひだからの捻り応力に耐えるようにするためには、セグメン トの壁厚をかなり厚くせねばならない。 この発明は、単に押し出し軸に限らず、複数個のセグメントより成る全ての押 し出し軸に適用可能である。 この発明は、セグメントと押し出し軸との間の結合を改善し、特に軸の相互連 結を容易ならしめるのに効果がある。 このために、螺旋、螺旋状穿腔まで、各隣接するセグメントには、案内套部が 挿入される凹状空腔が連結され、この套部を通してネジボルトが嵌着される。 この案内套部の利点は、複数個の同様な案内套部が環状リングに配設されてい るので、押し出し軸に作用する回転力が、この案内套部から得られる分力に分割 される。さらに1個の楔軸の使用により、この楔軸とセグメントとの間に錆び付 きが発生しない。案内套部は不錆鋼から成るので、個々のセグメントの間に錆は 発生せず、相互に容易に解消され、また簡単に取り替えることができる。 好ましくはセグメント内に配設された軸方向空腔は、楔軸で包囲しないで、必 要に応じ、軸の冷却または加熱用の媒体で使用することができる。 さらに前記記載の軸方向空腔の周りに、例えば螺旋ひだを有するスリーブ被覆 のように、スリーブ被覆をかなり薄く形成する。こうして、この螺旋状ひだによ って比較的薄いスリーブ壁自体を安定させる。 さらに、軸を外部フランジを介して、または変速フランジに 直接に連結することができるので、外部浸潤位置の個数がかなり少なくなる。 好ましくは、増径部の深さを案内套部の長さの約半分に形成する。これにより 対応する収納区画内にある案内套部を完全に消去することができ、捻りまたは回 転応力が作用する際に、これらを「せん断応力」として案内套部上に均等に分布 させることができる。 複数個の案内套部が円形環上に配設されるので、これら案内套部によって種々 の滑りも低減される。この際2個の押し出し軸が相互に連結されて、反対方向に または同一時計方向に回転されても、いずれでも等価となる。 図面の簡単な説明 第1図は、変速機構フランジを介して連結された押し出し装置の長さ方向分解 図; 第2図は、第1図の軸に沿った縦断面図; 第3図は、他の実施例における分解図; 第4図は、第3図の縦断面図; 第5図は、変速機構が結合された押し出し軸の他の実施例の分解図; 第6図は、変速機構が結合された押し出し軸のさらに他の実施例の分解図; 第7図は、第4図のV−Vに沿った断面図; 第8図および第9図は、さらに他の2種の実施例の縦断面図である。 実施例 第1図図示の通り、押し出し軸1は複数個のセグメント2、3、4より成り、 スリーブ外装6内の縦走腔5を備え、この外装の1個の外装表面7は、螺旋状外 皮8で包囲されている。セグメント2は複数個の螺旋外装を備えるが、セグメン ト3と4は、ほぼ1個だけの螺旋外装を備える。 セグメント3と4は、複数個のねじ込みボルト9で相互に連結され、これらの ボルト9は、セグメント2、3、4内の貫通孔に貫挿され、または穿孔に挿入さ れている。つまりセグメント2は有底孔10を備え、有底孔10の最奥部は雌ネ ジ部11として形成され、増径部12内へは、案内套部13を内挿することがで きる。この増径部12の深さtは、套部13の長さl(エル)の約半分とする。 次のセグメント3は、1個の透孔区画14の両側に、それぞれ1個の増径部1 2.1、12.2を備える。この増径部12.1には、案内套部13の残りのの 半分部分が、また、増径部12.1には、セグメント3と4との間の案内套部1 3.1が収納される。これに対応してセグメント4には、案内套部13.1の第 2の部分を収納するための増径部12.3が形成されている。 増径部12.3の位置には、他の1個の頂部空間16が開口するための他の1 個の穿孔区画15が開口され、この頂部空間16には、ねじ込みボルト9の頂部 17が収納される。 さらにセグメント4には、閉鎖板19が内挿された板状空腔18を形成するこ とができ、前記閉鎖板19を短軸ボルト20で固定すれば、閉鎖板19内のステ ップ空腔21内を貫通し、 螺旋空腔22内でセグメント4内に保持される。 セグメント2には、有底孔10の他端に、接続フランジ23が装着され、これ にも螺旋空腔24がある。ねじ込みボルト25により、変速軸27の位置におい て、減速フランジ26を接続フランジ23に連結することができる。これによっ てねじ込みボルト25が減速フランジ26を貫通して螺旋空腔24にねじ込まれ る。 第2図の通り、セグメント2、3、4および閉鎖板19は、適宜のねじボルト 9および短軸ボルト20によって押し出し軸1に締結され、接続フランジ23を 介して、ねじ込みボルト25により変速軸27の変速フランジ26に固定される 。 押し出し軸1と変速機構部材は、28.1から28.7までの種々の区画より 成るハウジング内に配置されている。さらに導入装置29を通過して、被処理物 質が内部空間29内へに導入される。 第3図と第4図の押し出し軸1.1の実施例は、第1、第2図とは異なり、区 画3.1が、第1図のセグメント3よりもかなり幅広く形成され、かつ多数の螺 旋外装8で包囲されている。セグメント3.1とセグメント2とを結合させるた めに追加の結合ネジ31を備え、収納空間12.2および空腔区画14.1を通 過して、適切なネジ駆動工具で操作することができる。この様に通常複数個のセ グメントが相互結合される(第6図、押し出し軸1.3参照)。 同様にしてセグメント3.1を、第5図のように、結合ネジ31により、1個 の変速機構33内にある変速フランジ 26.1と直接に連結させてもよい。さらにセグメント4と3.1並びに減速フ ランジ26.1との間に、図中に略示した密封リング34.1と34.2を付設 してもよい。 第7図中のハウジング板28.6は、2個の押し出し軸1a、1bを受容する ための2個の内部隔室30.1、30.2を閉鎖する。重畳されたハウジング板 を相互に結合するために、ハウジング板内に穿孔32が形成される。 押し出し軸には、案内スリーブ13.1のための空腔区画14.1および増径 部12.2が形成される。 第8図のような二重構造押し出し装置の場合には、隔室区画28内に、第6図 と同様に、1個の押し出し軸1.3が設けられる。勿論、ハウジング28内には 、生成物の排出口36を備えた摩擦板35が配設される。排出口36は、環状の 区画を介して押し出し装置の内部と連結され、この環状区画により合成樹脂区域 からの溶浸出分が排除される。 第9図では、排出板38内の円錐部39が、ネジ40で外側板41に結合され 、この円錐部39は、案内スリーブ13によりセグメント4に対して支持されて いる。 前記円錐部39と排出板38とで円錐状区画42が形成され、この区画を通過 して、被処理物質はさらに細隙通過されて排出される。DETAILED DESCRIPTION OF THE INVENTION Extruder consisting of multiple segments The present invention relates to individual segments secured by screw bolts in a housing. At least one rotatable extrusion shaft comprising: For performing chemical, chemical and / or physical treatments, wherein the bolts are The inside of the spiral cavity is inserted into the perforation in the It is surrounded by spiral folds. Extrusion shafts of this type are used in a variety of industrial fields, usually with electric motors or transmissions. The mechanism includes a wedge shaft housed in a wedge-shaped recess formed in the longitudinal cavity in the segment. Are connected. Especially in this case, the extruding shaft surrounded by the spiral pleats is mainly used. Yes, the extruded axis allows the product to be thermally, mechanically, chemically, and / or Undergoes physical processing. In other words, the torsional stress captured by gripping the wedge shaft Act on the pigment. Devices of this kind are described, for example, in Swiss Patent No. Patent application number PCT / CH83 / 0059 discloses the product Mechanically closed, especially fibrous, by two interacting extrusion axes Processed thermally. Rust is easy to rust, especially near the wedge shaft cavity. Difficult to change, especially when changing There are drawbacks. In particular, in order for the wedge shaft to withstand the torsional stress caused by the spiral, The thickness of the wall must be quite thick. The present invention is not limited to the extrusion shaft, but includes all extrusions composed of a plurality of segments. Applicable to the extruding shaft. The present invention improves the coupling between the segments and the extruded shaft, especially the interconnection of the shafts. This is effective for making the knot easier. To this end, each adjacent segment, up to the spiral and the helical bore, has a guide sleeve. The concave cavity to be inserted is connected, and a screw bolt is fitted through the sleeve. The advantage of this guide jacket is that a plurality of similar guide jackets are arranged on the annular ring. Therefore, the rotational force acting on the extrusion shaft is divided into the component force obtained from this guide sleeve. Is done. With the use of one more wedge shaft, there is rust between this wedge shaft and the segment. Does not occur. Since the guide sleeve is made of non-rusting steel, rust will not It does not occur, is easily eliminated from each other, and can be easily replaced. Preferably, the axial cavity arranged in the segment is not surrounded by a wedge axis, If desired, it can be used as a medium for cooling or heating the shaft. Furthermore, a sleeve covering, for example with helical pleats, around the axial cavity described above The sleeve coating is made quite thin. Thus, this spiral fold This stabilizes the relatively thin sleeve wall itself. In addition, the shaft can be connected to the external flange or to the shifting flange Because they can be connected directly, the number of external infiltration locations is significantly reduced. Preferably, the depth of the diameter increasing portion is formed to be about half the length of the guide sleeve. This The guide hood in the corresponding storage compartment can be completely erased, twisted or turned. When rolling stress is applied, these are evenly distributed on the guide sleeve as "shear stress". Can be done. Since a plurality of guide sleeves are arranged on a circular ring, various Is also reduced. At this time, the two extrusion shafts are connected to each other and Or, even if they are rotated in the same clockwise direction, they are all equivalent.
