Abstract
Description
本発明は、合流管渠から汚水流出管渠を経て、処理場へ流れる汚水路の途中に分岐接続した放流管渠の入り口に設けるタバコのフィルターや落葉等の微細ゴミの除塵装置に関するものである。 The present invention relates to a dust filter for fine dust such as tobacco filters and fallen leaves provided at the entrance of a discharge pipe that is branched and connected in the middle of a sewage channel that flows from a merging pipe to a treatment plant. .
周知のように、下水道において、入口に除塵スクリーンを配置した放流管渠を設けて、増水時に増水分を放流管渠に分流して、越流雨水を直接、公共水域に放流しているが、その場合の除塵装置として大型ゴミ(30mm以上)の除去については、各種の装置が提供されている。 As is well known, in the sewer, a discharge pipe with a dust screen is installed at the entrance, and when the water increases, the increased moisture is divided into the discharge pipe and the overflow rainwater is discharged directly into the public water area. Various devices are provided for removing large trash (30 mm or more) as a dust removal device in that case.
近年、水の浄化、放流水面の汚染防止および小型ポンプの普及により、タバコのフィルターや落葉等の微細ゴミが公共水域を汚染する虞があるとして、それらの除去が要求される傾向が増加している。 In recent years, with the purification of water, prevention of contamination of the discharged water surface, and the spread of small pumps, there is an increasing tendency that fine dust such as tobacco filters and fallen leaves may contaminate public water areas, and that their removal is required. Yes.
今迄に、これら微細ゴミの除去に、ネットを利用する例があるが、ネットに付着したゴミの洗浄には時間と費用を要し、目詰まり等により実用性に乏しいものが多い。
そこで本発明は、除塵スクリーン上に分離されたゴミの除去を水流の助けを借りて自動的に除去される放流管渠の除塵装置を提供することを課題とするものである。 SUMMARY OF THE INVENTION An object of the present invention is to provide a dust removal device for a discharge pipe that can automatically remove dust separated on a dust removal screen with the aid of a water flow.
本発明は上記の課題を解決するためになされたもので、下水道管渠の途中に雨水吐室を設け、この雨水吐室に接続した放流管渠の流入口前に越流堰を設け、この越流堰の手前に、目幅の狭い除塵スクリーンを配置し、且つこの除塵スクリーンと噛み合わせた櫛歯状の除塵レーキを昇降装置と連繋させると共に、この櫛歯状の除塵レーキにゴミ受け樋を設けたことを特徴とする放流管渠の往復式除塵装置である。 The present invention has been made to solve the above-described problems. A rainwater discharge chamber is provided in the middle of the sewer pipe, and an overflow weir is provided in front of the inlet of the discharge pipe connected to the rainwater discharge chamber. A dust-removing screen with a narrow mesh width is arranged in front of the overflow weir, and a comb-shaped dust removal rake meshed with the dust-removing screen is connected to the lifting device, and the comb-shaped dust removal rake receives dust. A reciprocating dust removing device for a discharge pipe tub, characterized in that.
前記ゴミ受け樋は下流側に傾斜させて設けることが好ましい。 It is preferable that the dust catcher is provided to be inclined to the downstream side.
また、除塵スクリーンは、ステンレス製の線材(例えばφ6mm)を用い各線材の下端を、櫛歯状に配置したバーブラケットにそれぞれ熔接し、上端をバー保持桁に挿通し、ナット等の緊張金具で張設してスクリーンバーを小間隔(例えばバーピッチ15mm)で配置し、しさの掻き取りを容易にした。 The dust removal screen is made of stainless steel wire (for example, φ6 mm), and the lower end of each wire is welded to a bar bracket arranged in a comb shape, and the upper end is inserted into a bar holding girder. The screen bars were stretched and arranged at small intervals (for example, a bar pitch of 15 mm) to facilitate scraping.
また、除塵レーキは掻き揚げ用と掻き下げ用のものを2段にそれぞれ上向き、下向きに設け、掻き取りを助ける構成とした。 In addition, the dust removal rake has a structure for scraping and scraping in two stages upward and downward to assist in scraping.
以上、本発明によれば、除塵レーキを上下にのみ往復させる構造が簡易な往復式除塵装置を使用するため、故障が少なく保守コストが少なくて済むと共に、下水道管渠に浮遊するタバコのフィルターや落葉等のゴミは放流管渠に流入する前に除塵スクリーンによって、放流管渠に流入するのを阻止され、除塵スクリーンに付着したゴミは櫛歯状の除塵レーキを上昇することによってゴミ受け樋上に掻き落され、ゴミ受け樋上のゴミは水流によって下流へと流される。 As described above, according to the present invention, since the reciprocating dust removing device having a simple structure for reciprocating the dust removing rake only in the up and down direction is used, the maintenance cost can be reduced and the tobacco filter floating in the sewer pipe can be reduced. The dust such as fallen leaves is prevented from flowing into the discharge pipe by the dust screen before flowing into the discharge pipe, and the dust adhering to the dust screen rises on the dust receptacle by raising the comb-shaped dust rake. The scraps are scraped off, and the garbage on the garbage receptacle is moved downstream by the water flow.
そして、ゴミ受け樋上のゴミは、ゴミ受け樋を下流側に傾斜させることにより、効率よく、水流により下流へ排除させることが出来る。 Then, the dust on the dust catcher can be efficiently removed downstream by the water flow by inclining the dust catcher downstream.
また、除塵スクリーンを線材(スクリーンバー)を以って構成し、一端を緊張金具により固定することにより、プレテンションを発生させて張力を保持させることにより、除塵スクリーンの細かいメッシュを保つことができ、タバコのフィルターや落葉等の細かいゴミをスクリーンで捕らえることができ、しかも除塵レーキによる付着したゴミの除去が容易になる。 Moreover, the fine screen of the dust removal screen can be maintained by constructing the dust removal screen with a wire rod (screen bar) and fixing one end with a tension fitting to generate a pretension and maintain the tension. In addition, fine dust such as tobacco filters and fallen leaves can be captured by the screen, and the attached dust can be easily removed by the dust removing rake.
又、櫛歯状の除塵レーキは、掻き揚げ用と掻き落し用のものを設けることにより、ゴミを除去スクリーンから、効果的に掻き落とすことができる除塵装置を提供することが出来る。 Moreover, the comb-tooth-shaped dust removal rake can provide a dust removal device that can effectively scrape dust from a removal screen by providing scraping and scraping.

図において、1は下水道管渠の途中に設けられた雨水吐室で、上流側の合流管渠1aと、ゴミを含んだ下水を下流側の汚水処理場へ排水させるための汚水流出管渠1bと、ゴミを除去した下水を一般河川に排水させる放流管渠1cが、図3に示すように接続されている。 In the figure, reference numeral 1 denotes a rainwater discharge chamber provided in the middle of a sewer pipe, and an upstream junction pipe 1a and a sewage outflow pipe 1b for draining sewage containing waste to a downstream sewage treatment plant. And the discharge pipe 1c which drains the sewage from which garbage was removed to a general river is connected as shown in FIG.
そして、放流管渠1cの流入口前には、越流堰1dが設けられ(図2参照)、更に越流堰1d前に往復式除塵機2が設けられている。 In addition, an overflow weir 1d is provided in front of the inlet of the discharge pipe 1c (see FIG. 2), and a reciprocating dust remover 2 is further provided in front of the overflow weir 1d.
往復式除塵機2は、除塵スクリーン3と、手動昇降装置4によって昇降する上段レーキ部5aと下段レーキ部5bとからなる櫛歯状の除塵レーキ5とから構成され、除塵スクリーン3は、ステンレス製の線材(例えばφ6mm)を用いたスクリーンバー3aを、図6に示すように櫛歯状に配置したバーブラケット6に下端を熔接し、上段はバー保持桁7に設けた透孔7aに挿通し、ナット8でプレテンションを与えて止め、スクリーンバー3aを小間隔(例えばバーピッチ15mm)に配置された除塵スクリーンとしたものである。 The reciprocating dust remover 2 includes a dust removing screen 3 and a comb-like dust removing rake 5 including an upper rake portion 5a and a lower rake portion 5b that are moved up and down by a manual lifting device 4. The dust removing screen 3 is made of stainless steel. As shown in FIG. 6, the lower end of the screen bar 3a using the wire rod (for example, φ6 mm) is welded to the bar bracket 6 arranged in a comb-teeth shape, and the upper stage is inserted into the through hole 7a provided in the bar holding girder 7. , The nut 8 is pretensioned and stopped, and the screen bar 3a is a dust removing screen arranged at a small interval (for example, a bar pitch of 15 mm).
除塵レーキ5の除塵スクリーン3の前面側にはゴミ受け樋9が下流側に傾斜させて設けられていて、前記手動昇降装置4を駆動させると、スピンドル10,10を介して昇降せしめられ、除塵レーキ5の端部はレーキガイド11,11によって案内されるように構成されている。 On the front side of the dust removing screen 3 of the dust removing rake 5, a dust receiving bowl 9 is inclined to the downstream side. When the manual elevating device 4 is driven, it is raised and lowered via the spindles 10 and 10 to remove dust. The end of the rake 5 is configured to be guided by rake guides 11 and 11.
図1及び図2の状態において、水位が低い通常時は、ゴミを含んだ下水は合流管渠1aから汚水流出管渠1bへ流出するが、雨天時に増水して水位が上がると下水は越流堰1dを越えて、放流管渠1cに流入する。その場合に下水に含まれるゴミは越流堰1dの前面に複数のスクリーンバー3aを密に併設された除塵スクリーン3により阻止されて放流管渠1cへ流入することはない。 In the state of FIG. 1 and FIG. 2, sewage containing garbage flows out from the merging pipe 1a to the sewage outflow pipe 1b at normal times when the water level is low, but when the water level rises in the rain and the water level rises, the sewage overflows It passes over the weir 1d and flows into the discharge pipe rod 1c. In this case, the dust contained in the sewage is not blocked by the dust removing screen 3 in which a plurality of screen bars 3a are closely arranged on the front surface of the overflow weir 1d and does not flow into the discharge pipe 1c.
そしてスクリーンバー3aに付着したゴミは、手動昇降装置4により除塵レーキ5を上昇させると、除塵レーキ5の上方に傾斜している上部レーキ部5aがスクリーンバー3aに付着したゴミをゴミ受け樋9上に掻き落とし、掻き落とされたゴミは水流によりゴミ受け樋9に沿って下流方向へ流される。 When the dust attached to the screen bar 3a is raised by the manual lifting device 4, the upper rake portion 5a inclined above the dust removing rake 5 removes the dust attached to the screen bar 3a. The garbage scraped up and scraped off is caused to flow in the downstream direction along the garbage receiver 9 by the water flow.
この場合、ゴミ受け樋9は下流側に傾斜して設けてあるため除塵レーキ5が水中から水面上に上昇する際に、ゴミが下流へと流されやすい構造と成っている。又、ゴミ受け樋9の側壁により除塵スクリーン3側への水流を防ぐので、ゴミ受け樋9内のゴミが流されて、再びスクリーンバー3aに付着し難い。 In this case, since the dust catcher 9 is provided to be inclined to the downstream side, when the dust removing rake 5 rises from the water to the surface of the water, the dust is easily flowed downstream. Moreover, since the water flow to the dust removing screen 3 side is prevented by the side wall of the dust catcher 9, the dust in the dust catcher 9 is caused to flow and hardly adheres to the screen bar 3a again.
又、除塵レーキ5が上昇した後に、スクリーンバー3aに付着したゴミは、除塵レーキ5の下降時に下段レーキ部5bにより掻き落される。 Further, after the dust removal rake 5 is raised, the dust adhering to the screen bar 3 a is scraped off by the lower rake portion 5 b when the dust removal rake 5 is lowered.
スクリーンバー3aは下端をバーブラケット6に固定し、上端にナット8を螺合してバー保持桁7に張設する構造としたので、ナット8を回転させることによりスクリーンバー3aの張力を調節して除塵スクリーン3を構成するスクリーンバー3aの間隔を均一に保つことができるので、除塵スクリーン3は一定の細かいメッシュを保つことができる。 The screen bar 3a has a structure in which the lower end is fixed to the bar bracket 6 and a nut 8 is screwed to the upper end so as to be stretched on the bar holding beam 7. Therefore, the tension of the screen bar 3a is adjusted by rotating the nut 8. Since the intervals between the screen bars 3a constituting the dust removing screen 3 can be kept uniform, the dust removing screen 3 can keep a constant fine mesh.
