Description
【0001】[0001]
本考案は、工業用水等の各種用水または汚泥水等の各種懸濁水の濾過もしくは 濃縮に使用される濾過筒において、周壁に多数の小孔を有する筒本体の外周に被 装された筒状濾布の開放端部の締着部構造に関する。 The present invention relates to a filtration cylinder used for filtering or concentrating various types of water such as industrial water or various types of suspended water such as sludge water. A cylindrical filter attached to the outer periphery of a cylinder body having a large number of small holes in its peripheral wall. The present invention relates to a structure of a fastening portion at an open end of cloth.

従来、この種濾過筒における濾布締着部構造として、筒本体の外周に筒状濾布 を被装し、該濾布の開放端部を金属ベルト、針金等の締着バンドで筒本体外周面 に強く締めつけた構成のものが広く知られている。 Conventionally, as a filter cloth fastening part structure in this kind of filtration tube, a tubular filter cloth is covered on the outer circumference of the tube body, and the open end of the filter cloth is attached to the outer circumference of the tube body with a fastening band such as a metal belt or wire. It is widely known that the surface is tightly clamped.

しかし、この従来構造では、濾過筒の使用により濾布外表面に付着した濾滓を 剥離除去するため、濾過筒の内部から濾布を通し外部へ向かって圧力水や圧縮空 気を噴出させる濾滓剥離洗浄作業を行った場合、濾布が内圧により膨張して上記 の濾布締着部に大きな引張り力が加わり、それにより締着バンドの締めつけが不 十分のときは濾布端部がはずれたり、締めつけが十分であっても剥離洗浄作業を 長期間繰返すと、締着部の濾布が伸びきって締着バンドの締めつけ力が減退し、 遂には濾布がはずれてしまう欠点があった。 本考案は、従来の欠点を除くことを課題とする。 However, in this conventional structure, since the filter cake is used to peel off and remove the filter residue attached to the outer surface of the filter cloth, the filter cloth that blows pressured water or compressed air from the inside of the filter tube to the outside through the filter cloth is used. When the slag peeling and cleaning work is performed, the filter cloth expands due to the internal pressure and a large tensile force is applied to the above-mentioned filter cloth fastening portion, which causes the filter cloth end to come off when the fastening band is not sufficiently tightened. Or, if the peeling and cleaning work is repeated for a long time even if the tightening is sufficient, the filter cloth at the tightening part stretches completely and the tightening force of the tightening band decreases, and finally the filter cloth comes off. . The present invention aims to eliminate the drawbacks of the prior art.

上記課題を解決する手段として、本考案は、 筒本体の外周に被装された筒状濾布の開放端部分において、 上記濾布の開放端部分を締着バンドにより筒本体外周面に締着すると共に、少 くとも上記締着バンドの環状端部と濾布との間に全周にわたって弾性粘着剤が施 こされて該締着バンドと濾布とを接合している、 濾過筒の濾布締着部構造を提案する。 As a means for solving the above-mentioned problems, the present invention provides an open end portion of a tubular filter cloth fitted on the outer circumference of a tubular body, wherein the open end portion of the filter cloth is fastened to the outer circumferential surface of the tubular body by a fastening band. In addition, an elastic adhesive is applied over the entire circumference at least between the annular end of the fastening band and the filter cloth to join the fastening band and the filter cloth, A fabric fastening structure is proposed.
【0005】 本考案における上記「締着バンド」とは、金属、合成樹脂、布等からなる帯状 バンド、上記材料からなる線状バンド、その他種々のバンドが含まれる。The “fastening band” in the present invention includes a band-shaped band made of metal, synthetic resin, cloth or the like, a linear band made of the above-mentioned material, and various other bands.
【0006】 また、上記「弾性粘着剤」は、ブタジエン系、ネオプレン系等の合成ゴム系粘 着剤、ゴム系粘着剤、もしくは合成樹脂系粘着剤等の弾性を持続するもので、好 ましくは適度の浸透性を有するものが使用される。これら弾性粘着剤は、そのま ま塗布するものに限らず、紙、アルミ箔、合成樹脂フィルム等のベースに塗着し たものを巻装することもよい。 以下図面を参照して本考案の実施例について説明する。The above-mentioned “elastic adhesive” is preferably one that maintains elasticity of a synthetic rubber-based adhesive such as a butadiene-based or neoprene-based adhesive, a rubber-based adhesive, or a synthetic resin-based adhesive. The one having a suitable permeability is used. These elastic pressure-sensitive adhesives are not limited to those applied as they are, and those applied to the base such as paper, aluminum foil, and synthetic resin film may be wound. An embodiment of the present invention will be described below with reference to the drawings.

図1において、周壁に多数の小孔(2)…を有する両端閉成の円筒本体(1) 内に、その一端から濾液取出し用内管(3)を挿通し、この円筒本体(1)の外 周に織布からなる円筒状濾布(4)を被装し、該濾布(4)の両開放端部分を濾 布締着部構造(A)により円筒本体(1)の外周面にそれぞれ締着してある。 In FIG. 1, an inner pipe (3) for taking out filtrate is inserted from one end into a cylindrical main body (1) having a large number of small holes (2) ... The outer circumference is covered with a cylindrical filter cloth (4), and both open end portions of the filter cloth (4) are attached to the outer peripheral surface of the cylindrical body (1) by the filter cloth fastening portion structure (A). Each is fastened.
【0008】 上記濾布締着部構造(A)は次のようである。図2において、円筒本体(1) の端部寄り外周面に環状凹溝(5)及びその若干中間寄りに環状凸条(6)をそ れぞれ設け、該凹溝(5)内にゴム等の帯状弾性下地材(7)を設置し、この弾 性下地材(7)の上に円筒状濾布(4)の開放端部分を被装し、ついで上記濾布 (4)の弾性下地材(7)に対応する外周面に、一例として金属帯状バンドから なる締着バンド(8)を巻きつけて該濾布(4)を弾性下地材(7)を介して円 筒本体(1)外周面に締着する。The filter cloth fastening structure (A) is as follows. In FIG. 2, an annular groove (5) and an annular ridge (6) are provided on the outer peripheral surface of the cylindrical body (1) near the end, and an annular ridge (6) slightly in the middle of the groove. A band-shaped elastic base material (7) such as the above is installed, the open end portion of the cylindrical filter cloth (4) is covered on the elastic base material (7), and then the elastic base material of the filter cloth (4) is provided. On the outer peripheral surface corresponding to the material (7), for example, a fastening band (8) made of a metal band is wound, and the filter cloth (4) is inserted through the elastic base material (7) into the cylindrical body (1). Tighten the outer peripheral surface.
【0009】 次に、合成ゴム系の弾性粘着剤(9)を、上記締着バンド(8)の上下両環状 端部(10)、(10)と濾布(4)との間の開先状凹部をはじめ、本例では締 着バンド(8)の外周面に全面にわたって塗布する。Next, a synthetic rubber elastic adhesive (9) is applied to the groove between the upper and lower annular ends (10) and (10) of the fastening band (8) and the filter cloth (4). In this example, the entire surface is applied to the outer peripheral surface of the fastening band (8) including the concave portions.
【0010】 このようにすれば、上記粘着剤(9)が濾布(4)と締着バンド(8)を弾性 を保持した状態に接合し、特に粘着剤(9)が締着バンド(8)下面の濾布(4 )内に相当量浸透して、その部分で濾布(4)と締着バンド(8)を接合する。In this way, the adhesive (9) joins the filter cloth (4) and the fastening band (8) in a state where elasticity is maintained, and in particular, the adhesive (9) is fastened to the fastening band (8). ) A considerable amount penetrates into the filter cloth (4) on the lower surface, and the filter cloth (4) and the fastening band (8) are joined at that portion.
【0011】 なお、弾性粘着剤(9)の塗布部を整えるために、上記濾布(4)の上端やや 上から弾性粘着剤(9)全面、ついで凸条(6)の若干下までの範囲をカバー( 11)により全面的に被覆してもよい。上記カバー(11)としては、一例とし てポリ塩化ビニル、ポリエチレン、シリコンゴム等の熱収縮性フィルムからなる チューブを被覆した後加熱により収縮させて形成される。このほか、ゴムチュー ブを被着させたり、テープもしくは接着テープを巻きつける等によるものもよい 。In order to arrange the application portion of the elastic adhesive agent (9), the range from slightly above the upper end of the filter cloth (4) to the entire surface of the elastic adhesive agent (9) and then slightly below the ridge (6). May be entirely covered with the cover (11). The cover (11) is formed, for example, by coating a tube made of a heat-shrinkable film of polyvinyl chloride, polyethylene, silicon rubber or the like, and then shrinking it by heating. Alternatively, a rubber tube may be attached, or tape or adhesive tape may be wrapped around.
【0012】 図3の他の実施例は、薄葉紙からなるベース(15a)に塗着された合成ゴム 系弾性粘着剤(9a)を、締着バンド(8a)の外周面及び該締着バンド(8a )の上下両環状端部(10a)、(10a)と濾布(4a)との間の凹部に貼着 し、他の構造は図1、2と実質的に同一の例である。In another embodiment shown in FIG. 3, a synthetic rubber-based elastic adhesive (9a) applied to a base (15a) made of thin paper is attached to the outer peripheral surface of the fastening band (8a) and the fastening band (8a). 8a) is affixed to the recesses between the upper and lower annular ends (10a), (10a) and the filter cloth (4a), and the other structures are substantially the same as in FIGS.

本考案の濾過筒の濾布締着部構造によれば、弾性粘着剤により濾布と締着バン ドを接合し、濾滓の剥離洗浄作業を長期間繰返しても濾布の締着状態を維持する ことができるようになり、それに伴い締着バンドの濾布締めつけ圧が従来よりも 数段低いもので足りることとなるから、締めつけ作業を簡易化でき、作業能率の 向上にも資するのである。 According to the filter cloth fastening portion structure of the filter cylinder of the present invention, the filter cloth and the fastening band are joined by the elastic adhesive so that the filter cloth is fastened even if the filter cake peeling and washing operation is repeated for a long time. It is possible to maintain the pressure, and the filter cloth tightening pressure of the tightening band is required to be several steps lower than the conventional pressure, so that the tightening work can be simplified and the work efficiency can be improved. .
