Description
【０００１】[0001]
本考案は、ろ過筒等の、ろ材ユニットを収める為の、耐圧構造を備えたプラス チック製の筒状ハウジングを備えたものに於いて、開放筒端の開閉蓋を、極力製 作コストを押さえながら、迅速・確実に開閉出来る様にしたろ過装置の蓋開閉構 造に関する。 The present invention minimizes manufacturing costs by using an open / close lid at the end of the open cylinder, which has a pressure-resistant plastic housing to accommodate the filter media unit, such as a filter cylinder. However, the present invention relates to a filter opening and closing structure that can be quickly and reliably opened and closed.
【０００２】[0002]
上記のタイプのろ過装置の筒状ハウジングは、必要な耐圧強度を確保する等の 為に、従来は、金属で作るのが一般だった。 然し、昨今では、金属に比べて、軽く、耐蝕性に優れ、成形が容易等の特性を 備えた、プラスチック製の筒状ハウジングが普及しつつある。 Conventionally, the cylindrical housing of the above-mentioned type of filtration device was generally made of metal in order to ensure necessary pressure resistance. However, recently, plastic tubular housings having characteristics such as lighter weight, better corrosion resistance, and easier molding than metal are becoming popular.
【０００３】[0003]
その場合に、筒状ハウジングの筒端を塞ぐ開閉蓋の開閉構造が問題となる。 一般的に考えられるは、筒状ハウジングの開放筒端及び開閉蓋の夫々の外周り に、互いに当接させるフランジを一体に設けて置き、両フランジの周方向の複数 個所に設けた貫通孔に締結ボルトを挿通させて、ナットで締付ける方法が考えら れる。 In that case, the opening / closing structure of the opening / closing lid for closing the cylindrical end of the cylindrical housing becomes a problem. It is generally considered that flanges to be brought into contact with each other are integrally provided around the open cylinder end of the cylindrical housing and the outer periphery of the open / close lid, and are placed in through holes provided at multiple locations in the circumferential direction of both flanges. A possible method is to insert a fastening bolt and tighten with a nut.
【０００４】 然しながら、この構造によると、開蓋時には、総ての締結ボルトからナットを 完全に螺脱させ、蓋閉時には、１本１本の締結ボルトをその貫通孔に挿通させた うえ、一々ナットを嵌め込むという、甚だ手間・暇の掛かる作業を要する。 その上、一旦、取り外したボルトやナットを、見失なわない様に保管して置く 手間も掛かる。However, according to this structure, when the lid is opened, the nuts are completely screwed off from all the fastening bolts, and when the lid is closed, each fastening bolt is inserted into its through hole, It takes a lot of time and effort to fit the nuts. In addition, it is time-consuming to store the bolts and nuts once removed so that they are not lost.
【０００５】 この様な不都合を無くすには、締結ボルトの基端側を、筒状ハウジングの開放 端の個所にピン連結して、このピンの周りに揺動自在とした、いわゆる“スイン グボルト”を用い、このボルトに蝶ナット等のナットを螺着させたままで、蓋の 外周りのフランジ部に設けた切欠部に、ボルトを側方から嵌込む方法が一般的に 考えられる。 その場合、スイングボルトの取付個所は、蓋締付圧の均等な分散と、蓋を確実 に液密固定させる為に、４個所以上とすることが望ましい。In order to eliminate such inconvenience, a so-called “swing bolt” is used in which the base end of the fastening bolt is connected to a pin at the open end of the cylindrical housing so as to be swingable around the pin. It is generally conceivable to insert the bolt from the side into a notch provided in the flange around the outside of the lid while screwing a nut such as a wing nut onto the bolt. In this case, it is desirable that four or more swing bolts be installed to evenly disperse the lid tightening pressure and securely fix the lid in a liquid-tight manner.
【０００６】 ところが、この方法によると、筒状ハウジング側には、連結ピンを組付ける為 の軸受部を設ける必要が生ずる。 筒状ハウジングはプラスチック製なので、生産性を考えれば、この軸受部は筒 状ハウジングと一体に射出成形するのが最も望ましい。However, according to this method, it is necessary to provide a bearing for attaching the connecting pin to the cylindrical housing. Since the cylindrical housing is made of plastic, it is most desirable that the bearing be integrally molded with the cylindrical housing in view of productivity.
【０００７】 然し、射出成形法を採用すると、複雑な形状の軸受部を、然も、多数個所に備 えた成形型の製作に、著しく高額な支出を余儀なくされることになる。 その為、大量生産の可能性の少ないろ過装置にとっては、上記の一体射出成形 法は採用し難い。However, when the injection molding method is adopted, a considerably high expenditure is required for manufacturing a molding die having a complicatedly shaped bearing portion in many places. For this reason, it is difficult to employ the above-described integral injection molding method for a filtration device that is unlikely to be mass-produced.
【０００８】 そこで、本考案の目的は、プラスチック製の筒状ハウジングの開放筒端を塞ぐ 開閉蓋を備えたろ過装置に就いて、蓋の開閉操作の迅速性を考慮しながら、製作 費を極力抑制出来る様に構成された蓋開閉構造を提供するにある。Accordingly, an object of the present invention is to provide a filtration device having an opening / closing lid for closing an open cylindrical end of a plastic cylindrical housing, and to minimize the manufacturing cost while considering the quickness of opening / closing operation of the lid. An object of the present invention is to provide a lid opening / closing structure configured so as to be able to be suppressed.
【０００９】[0009]
上記の目的を達成する為の、本考案によるろ過装置の蓋開閉構造は、 プラスチック製の筒状ハウジングを備えたものに於いて、開放筒端を塞ぐ開閉 蓋を、その基端部を支点として揺動自在としたスイングボルト・ナットを用いて 開閉する為の構造であって、 筒状ハウジングの開放端及び開閉蓋の夫々の外周りに、互いに当接させるフラ ンジを一体に設け、 筒状ハウジング側のフランジの背面の、所定間隔を距てた複数個所に、スイン グボルトの基端部を揺動自在に支持する為の、筒状ハウジングとは別体に作られ た軸受部材を、適宜の固定手段によって固着したことを特徴とする。 前記固定手段として、螺止するか、又は、接着乃至は熱融着するか、或いは、 軸受部材及び筒状ハウジングに、互いに嵌まり合う嵌合用凹部及び凸部を設けて もよい。 In order to achieve the above object, the filter opening / closing structure of the filtration device according to the present invention is provided with a plastic tubular housing provided with an opening / closing lid closing an open cylindrical end, and a base end serving as a fulcrum. This is a structure for opening and closing using swingable swing bolts and nuts.Flanges to be in contact with each other are integrally provided around the open end of the cylindrical housing and the outer periphery of the open / close lid. A bearing member made separately from the cylindrical housing to support the base end of the swing bolt so that it can swing freely at a plurality of places at a predetermined distance behind the flange on the housing side. Characterized by being fixed by the fixing means. The fixing means may be screwed, bonded or heat-fused, or provided with a fitting concave portion and a convex portion which are fitted to each other on the bearing member and the cylindrical housing.

A wing nut 13 that is tightened by hand is screwed into the tip of the swing bolt. However, this nut is of course not limited to the wing nut 13.
【００１６】 次に、図２〜図４に、この実施例の軸受部材Ｄの具体的な形状を示した。図２ は平面図、図３は半縦断正面図、図４は側面図で、筒状ハウジングＢへの取付状 態の説明図も兼ねている。Next, FIGS. 2 to 4 show specific shapes of the bearing member D of this embodiment. 2 is a plan view, FIG. 3 is a semi-longitudinal front view, and FIG. 4 is a side view, which also serves as an explanatory view of a state of attachment to the cylindrical housing B.
【００１７】 この軸受部材Ｄは、図３、図４に示した様に、筒状ハウジングＢの外周面に当 接させる湾曲板状のベース部２１と、ベース部の頂端から外向きに延設されて、 フランジ８の下面に当接させる取付部２２と、揺動用支軸１１を組付ける為の軸 受部２３とで構成されている。As shown in FIGS. 3 and 4, the bearing member D has a curved plate-shaped base portion 21 that comes into contact with the outer peripheral surface of the cylindrical housing B, and extends outward from the top end of the base portion. Then, it is composed of a mounting portion 22 to be brought into contact with the lower surface of the flange 8 and a bearing portion 23 for mounting the pivot 11.

A shaft hole 23a through which the swing support shaft 11 is inserted is formed in the bearing portion 23 provided with a loose fitting groove a into which the swing bolt 10 is loosely fitted. On the other hand, as shown in FIG. 4, the flange 8 of the cylindrical housing B is provided with a screw hole 8a at a position opposed to each screw hole 22a.
【００１９】 次に、この実施例の蓋開閉構造の組立手順に就いて、その一例を説明する。 図１に示したろ過装置の組立に先だって、上段側の筒状ハウジングＢのフラン ジ８には、既述の如く、計６個所に軸受部材Ｄを取付ける。Next, an example of an assembling procedure of the lid opening / closing structure of this embodiment will be described. Prior to assembling the filtration device shown in FIG. 1, bearing members D are attached to the flange 8 of the upper cylindrical housing B at a total of six locations as described above.
【００２０】 それには、軸受部材Ｄのベース部２１を、筒状ハウジングＢの外周面に、又、 取付部２２を、フランジ８の下面の所定位置に夫々当てがう。 この状態で、取付部２２とフランジ８とを貫通する１組のビス孔２２ａ、８ａ に、図示は省いたが、ビスを挿通させたうえ、ナットを螺着して締付ければよい 。 そして、上側のビス孔８ａに残された凹みは、適宜のシーリング材を充填して 塞ぐとよい。To this end, the base portion 21 of the bearing member D is applied to the outer peripheral surface of the cylindrical housing B, and the mounting portion 22 is applied to a predetermined position on the lower surface of the flange 8. In this state, although not shown, screws may be inserted into a pair of screw holes 22a, 8a penetrating the mounting portion 22 and the flange 8, and a nut may be screwed and tightened. Then, the recess left in the upper screw hole 8a is preferably filled with an appropriate sealing material and closed.
【００２１】 計６個の軸受部材Ｄを取付け終えたら、次に、ろ過装置のハウジング部分の組 立に掛かる。 それには、図１に示した様に、ベースユニットＡの上に、下段側の筒状ハウジ ングＢを、ボルト・ナット６によって液密に連結させ、更に、その上に、軸受部 材Ｄを取付済みの筒状ハウジングＢを同様にして連結させる。 そして上段の筒状ハウジングＢに、開閉蓋Ｃを、ヒンジ７の個所で連結させれ ば、上記の組立は完了する。After the mounting of the six bearing members D, the assembling of the housing portion of the filtration device is started. For this purpose, as shown in FIG. 1, a lower cylindrical housing B is connected to a base unit A in a liquid-tight manner by bolts and nuts 6, and a bearing member D is further mounted thereon. The mounted tubular housing B is connected in the same manner. Then, when the lid C is connected to the upper cylindrical housing B at the hinge 7, the above-described assembly is completed.
【００２２】 このろ過装置の使い方は、筒状ハウジングＢを二段連結して形成させたろ過室 内に、図１に示した様に、複数本のカートリッジ式のろ過筒５を、説明は省くが 、所定の手順に従ってセットする。 然る後、開閉蓋Ｃを閉じて、計本６組のスイングボルト１０と蝶ナット１３に よって液密に締め付ければ、ろ過装置の使用準備が整う。As shown in FIG. 1, a plurality of cartridge-type filter tubes 5 are omitted in a filter chamber formed by connecting cylindrical housings B in two stages. Is set according to the prescribed procedure. Thereafter, the opening / closing lid C is closed, and the filter device is ready for use by tightening the total of six sets of the swing bolts 10 and the wing nuts 13 in a liquid-tight manner.
【００２３】 そこで、送液ポンプ４を起動させると、液入口１からろ過室内に圧入された被 ろ過液は、各ろ過筒５の外周面から筒内に向けて強制透過させられることにより ろ過作用を受ける。 このろ過済み液は、ろ過筒５の筒内下端から、べースユニットＡ内に設けた出 口ポート（図示略）を経て、液出口２から排出される。Therefore, when the liquid feed pump 4 is started, the liquid to be filtered, which has been pressed into the filtration chamber from the liquid inlet 1, is forcibly permeated from the outer peripheral surface of each of the filtration tubes 5 into the inside of the filtration tube, whereby the filtration action is performed. Receive. The filtered liquid is discharged from the lower end of the filter tube 5 through the outlet port (not shown) provided in the base unit A and from the liquid outlet 2.
【００２４】 そして、ろ過筒５の外周面にろ滓が堆積して来たら、ろ過筒５を洗浄する為に 、又は、新しいろ過筒５に取り替える為に、送液ポンプ４を停止させたうえ、開 閉蓋Ｃを開く。 この開蓋作業は、単に、６個の蝶ナット１３を緩めたうえ、各スイングボルト １０を、揺動用支軸１１を支点として外向きに倒すだけで足りる。When the filter cake accumulates on the outer peripheral surface of the filter tube 5, the liquid feed pump 4 is stopped to clean the filter tube 5 or to replace the filter tube 5 with a new filter tube 5. Open the lid C. For this lid opening operation, it is sufficient to simply loosen the six wing nuts 13 and then tilt each swing bolt 10 outward with the swing support shaft 11 as a fulcrum.
【００２５】 そして、ろ過装置を再使用する為に、開閉蓋Ｃを閉ざす時には、上記と逆の操 作を行うだけで、迅速・確実に蓋閉じ操作を終えることが出来る。Then, when closing the opening / closing lid C in order to reuse the filtration device, the lid closing operation can be quickly and reliably completed simply by performing the reverse operation.
【００２６】 又、蓋無しの標準タイプの筒状ハウジングＢを、必要に応じて、蓋付タイプに 変える為に、軸受部材Ｄを取付ける作業も、既述の如くして、極めて簡単・迅速 に行える。 もっとも、この場合は、開閉蓋Ｃを連結させる為のヒンジ７を欠くことになる 。Also, in order to change the standard type cylindrical housing B without a lid to a type with a lid as necessary, the operation of mounting the bearing member D is extremely simple and quick as described above. I can do it. However, in this case, the hinge 7 for connecting the opening / closing lid C is missing.
【００２７】 尚、上記実施例に於いて、軸受部材Ｄを、筒状ハウジングＢの所定個所に取付 ける為の固定手段は、ビス等の止螺に限らず、例えば、共に、熱融着性プラスチ ック製の軸受部材Ｄと、筒状ハウジングＢとを、周知の熱融着手段によって結合 させてたり、接着剤を使って固定させてもよい。 或いは、これ等両者の当接個所に、互いに嵌まり合う嵌合用凹部及び凸部を設 ける方法を採ることも出来る。In the above embodiment, the fixing means for attaching the bearing member D to a predetermined position of the cylindrical housing B is not limited to a set screw such as a screw. The plastic bearing member D and the cylindrical housing B may be connected to each other by a known heat sealing means, or may be fixed using an adhesive. Alternatively, it is also possible to adopt a method in which fitting concave portions and convex portions that fit with each other are provided at the contact points of these two.
