Abstract
Description
本発明は、浄水場の沈殿池設備に設置される上向流式沈降装置に使用される傾斜管ユニットに関し、特に現場での補修が可能であり、有機溶剤が溶出する恐れのない傾斜管ユニットとその製造方法に関するものである。 The present invention relates to an inclined pipe unit used for an upflow type settling device installed in a settling pond facility of a water purification plant, and in particular, an inclined pipe unit that can be repaired in the field and has no fear of elution of an organic solvent. And its manufacturing method.
本発明の傾斜管ユニットは、図１に示す沈殿池設備に、浮遊物などを効率よく沈殿させる目的で設置される上向流式沈降装置に使用されるものであり、一般的には、沈殿池１内に傾斜管ユニットから構成される上向流式沈降装置２が配置され、上向流式沈降装置２の上部に集水トラフ３、下部に水が流入する流入室４が配置されている。 The inclined pipe unit of the present invention is used for an upflow type settling device installed in the settling basin facility shown in FIG. An upward flow settling device 2 composed of an inclined pipe unit is arranged in the pond 1, a water collecting trough 3 is arranged in the upper part of the upward flow settling device 2, and an inflow chamber 4 into which water flows is arranged in the lower part. Yes.
沈殿池１の側部には整流壁５が配置され、該整流壁５を通して整流された水が流入室４に流入するようになっている。
該流入室４に流入した水は上向流式沈降装置２の下端流入部に流入する。上向流式沈降装置２内においては、流入水は固液分離されて、水は上昇して集水トラフ３に流れ込む。流水中の汚泥は上向流式沈降装置２内で分離され、傾斜面を滑り落ち、流入室４を沈降し、該流入室４の底部に堆積する。堆積したフロック、即ち汚泥は汚泥排出装置６で排泥ピット７に集められた後、沈殿池１の外に排出されるようになっている。
A rectifying wall 5 is disposed on the side of the settling basin 1, and water rectified through the rectifying wall 5 flows into the inflow chamber 4.
The water flowing into the inflow chamber 4 flows into the lower end inflow portion of the upward flow settling device 2. In the upward flow settling device 2, the incoming water is separated into solid and liquid, and the water rises and flows into the water collecting trough 3. Sludge in the flowing water is separated in the upward flow settling device 2, slides down the inclined surface, sinks the inflow chamber 4, and accumulates at the bottom of the inflow chamber 4. The accumulated flock, that is, sludge is collected in the sludge pit 7 by the sludge discharge device 6 and then discharged out of the sedimentation basin 1.
上記沈殿池１に設置される上向流式沈降装置は、浮遊物の沈降距離が短いほど効率的に沈降分離できることに着目し、角型管等を約６０度に傾斜させた傾斜沈降装置であり、その角型管内に水流を通過させ沈降距離を短くしたものである。 The upward flow settling device installed in the settling basin 1 is an inclined settling device in which a square tube or the like is inclined at about 60 degrees, paying attention to the fact that the sedimentation and separation can be performed more efficiently as the settling distance of the suspended matter is shorter. Yes, the water flow is passed through the rectangular tube to shorten the settling distance.
沈降物を受ける部材として、一般的には平板や角型管、ハニカム断面管などが使用される。角型管相互や角型管と平板などの接合は、従来、接着剤が使用されている。
なお、使用樹脂としては、ＰＶＣ（ポリ塩化ビニール）、ＡＢＳ樹脂（アクリロニトリル−ブタジエン−スチレン共重合樹脂）などが使用される。
In general, a flat plate, a square tube, a honeycomb cross-section tube or the like is used as a member for receiving the sediment. Conventionally, an adhesive is used to join the square tubes to each other or between the square tubes and the flat plate.
In addition, as the resin used, PVC (polyvinyl chloride), ABS resin (acrylonitrile-butadiene-styrene copolymer resin), or the like is used.
本願発明で使用する上向流式沈降装置としては、傾斜した角型管と平板とを複数組み合わせた図２のような傾斜管ユニットからなる上向流式沈降装置を対象とし、実際に使用するときは、この傾斜管ユニットを図１の沈澱池設備に複数ユニット設置して上向流式沈降装置として使用する。 As the upward flow settling device used in the present invention, the upward flow settling device comprising the inclined tube unit as shown in FIG. 2 in which a plurality of inclined square tubes and flat plates are combined is actually used. In some cases, a plurality of such inclined pipe units are installed in the settling basin facility of FIG.
図２に示す傾斜管ユニットは、従来、熱可塑性樹脂からなる平板に一定間隔で傾斜管を接着剤で貼り付け、それを複数段積み重ねて、各層間を接着剤で固定する方法で製造されている（図３参照）。 The inclined pipe unit shown in FIG. 2 is conventionally manufactured by a method in which inclined pipes are attached to a flat plate made of a thermoplastic resin at a predetermined interval with an adhesive, stacked in a plurality of stages, and each layer is fixed with an adhesive. (See FIG. 3).
したがって、沈澱池設備に上記傾斜管ユニットからなる上向流式沈降装置を設置した場合、角型傾斜管相互や角型傾斜管と平板との接合に接着剤が使用されているため、作業環境上の問題や接着剤に含まれる有機溶剤などが沈澱水に溶出する問題があった。 Therefore, when an upflow type settling device consisting of the above-mentioned inclined pipe unit is installed in the settling basin equipment, the adhesive is used for joining the rectangular inclined pipes to each other and the rectangular inclined pipe and the flat plate. There was a problem that the organic solvent contained in the adhesive was dissolved into the precipitated water.
また、上記上向流式沈降装置の補修時にも接着剤が使用されることから、補修時においても同様な問題が生じていた。
さらに、傾斜管ユニットの製造に使用される接着剤そのものも、水に溶出する接着剤が使用されているため、経年劣化が生じる欠点もあった。
Moreover, since an adhesive is used also at the time of repair of the said upflow type sedimentation apparatus, the same problem had arisen at the time of repair.
Furthermore, the adhesive itself used for manufacturing the inclined pipe unit also has a drawback in that it deteriorates over time because an adhesive eluting in water is used.
熱可塑性樹脂同士の接合では超音波などの溶着で行う方法もあり、傾斜管ユニットの製造においても、接着剤を使用しない方法として溶着で行う方法が考えられる。
しかし、角型管相互あるいは角型管と平板などの溶着において、傾斜管の上端・下端近くの箇所での溶着は可能であるが、角型管は幅寸法が５０〜１００ｍｍ、長さは５００〜１５００ｍｍ、厚さ０．７ｍｍ程度であるため、傾斜管の深さ方向の中間部の溶着には特殊な機器を用いる必要があり、かつ、厚みが薄いことから、それらの部材に対して安定した溶着は困難であると考えられていた。
There is a method in which bonding of thermoplastic resins is performed by welding such as ultrasonic waves, and in manufacturing an inclined tube unit, a method in which welding is performed as a method not using an adhesive is conceivable.
However, in the welding of rectangular tubes to each other or from a rectangular tube and a flat plate, welding is possible at locations near the upper and lower ends of the inclined tube, but the rectangular tube has a width of 50 to 100 mm and a length of 500. Because it is ~ 1500mm and thickness is about 0.7mm, it is necessary to use special equipment for welding the intermediate part in the depth direction of the inclined pipe, and since it is thin, it is stable against those members Welding was considered difficult.
また、熱可塑性樹脂を溶着すると、その溶着箇所に若干の凹凸ができ、この凹凸が傾斜管内部のフロックの沈降を阻害する恐れがあることから、傾斜管ユニットの製造現場では、溶着による接合はこれまで試みられてこなかった。 In addition, when thermoplastic resin is welded, some unevenness is formed at the welding location, and this unevenness may hinder sedimentation of flocs inside the inclined pipe. Never tried before.
さらに、傾斜管ユニットを用いた沈降装置の設置時には、特に、上端・下端部が損傷することがあり、そのような場合は、現地にて補修する必要があるが、施行現場での特殊な溶着機器を設置した補修は困難であることも、傾斜管ユニットの製造において、これまで溶着による接合が試みられることがなかった一因である。
本発明の目的は、沈降装置の設置現場においても施工可能な、溶着方法による上向流式沈降装置を製造することにある。
In addition, when installing a sedimentation device using an inclined pipe unit, the upper and lower ends may be damaged, and in such cases, it is necessary to repair them on site. It is difficult to repair the equipment installed, which is one of the reasons why joining by welding has not been attempted in the manufacture of the inclined pipe unit.
An object of the present invention is to manufacture an upward flow type settling device by a welding method that can be constructed even at the installation site of the settling device.
本発明は上述の点に鑑みてなされたもので、有機溶剤の溶出の恐れや経年での接着剤の劣化の問題がなく、また、管内部のフロックの沈降を阻害する恐れがなく、現場での補修も容易にでき、さらに、作業環境上の問題が無い上向流式沈降装置に使用する傾斜管ユニット及びその製造方法を提供することを目的とする。 The present invention has been made in view of the above points, and there is no fear of elution of an organic solvent or deterioration of the adhesive over time, and there is no risk of hindering the sedimentation of flocs inside the pipe. It is an object of the present invention to provide an inclined pipe unit for use in an upward flow settling device which can be easily repaired and has no problem in the working environment, and a method for manufacturing the same.
上記課題を解決するため、請求項１に記載の上向流式沈降装置に使用する傾斜管ユニットの発明は、熱可塑性樹脂で形成された平板及び角型管を複数組み合わせてなる傾斜管ユニットであって、上記平板と角型管とが溶着により接合され、該接合部が設置時に側面となることを特徴とする。
請求項２に記載の発明は、請求項１に記載の上向流式沈降装置に使用する傾斜管ユニットにおいて、使用する熱可塑性樹脂がポリエチレンテレフタレート樹脂、ポリ塩化ビニル樹脂及びＡＢＳ樹脂から選ばれる１種又は２種以上の樹脂であることを特徴とする。
In order to solve the above-mentioned problem, the invention of the inclined tube unit used in the upward flow settling device according to claim 1 is an inclined tube unit formed by combining a plurality of flat plates and square tubes formed of a thermoplastic resin. And the said flat plate and a square tube are joined by welding, and this junction part turns into a side surface at the time of installation, It is characterized by the above-mentioned.
The invention according to claim 2 is the inclined pipe unit used in the upward flow settling device according to claim 1, wherein the thermoplastic resin used is selected from polyethylene terephthalate resin, polyvinyl chloride resin and ABS resin. It is a seed or two or more kinds of resins.
請求項３に記載の上向流式沈降装置に使用する傾斜管ユニットの製造方法の発明は、熱可塑性樹脂で形成された平板及び角型管を複数組み合わせてなる傾斜管ユニットの製造方法であって、角型管の中に受架台を挿入し、平板側から角型管と平板とを部分的又は全面に亘って溶着により接合することを特徴とする。 The invention of the manufacturing method of the inclined pipe unit used for the upward flow type sedimentation apparatus according to claim 3 is a manufacturing method of the inclined pipe unit formed by combining a plurality of flat plates and square tubes formed of a thermoplastic resin. Then, a cradle is inserted into the rectangular tube, and the rectangular tube and the flat plate are joined from the flat plate side by partial or entire surface welding.
請求項４に記載の発明は、請求項３に記載の上向流式沈降装置に使用する傾斜管ユニットの製造方法において、平板と角型管との接合が超音波、熱板又は高周波を用いた溶着にて行われることを特徴とする。
請求項５に記載の発明は、請求項３又は４に記載の上向流式沈降装置に使用する傾斜管ユニットの製造方法において、溶着による接合を空気冷却下で行うことを特徴とする。
According to a fourth aspect of the present invention, in the manufacturing method of the inclined tube unit used in the upward flow settling device according to the third aspect, the joining of the flat plate and the square tube uses an ultrasonic wave, a hot plate or a high frequency. It is performed by welding.
According to a fifth aspect of the present invention, in the manufacturing method of the inclined pipe unit used in the upward flow settling apparatus according to the third or fourth aspect, the joining by welding is performed under air cooling.
上向流式沈降装置に使用する傾斜管ユニットの製造に接着剤を使用しないことで、接着剤から水道水に溶出する有機溶剤などがゼロとなることから、飲料水としての水道水の安全性が高まると同時に、接着剤の経年劣化による傾斜管ユニットの損傷の恐れも回避することができる。
また、従来、接着剤では十分な接着強度が実現できなかったＡ−ＰＥＴ（ポリエチレンテレフタレート）等の材料も、溶着法を採用することにより実用上問題がない接着強度が得られ、使用可能な樹脂材料の選択の幅が広がり、傾斜管ユニットの設置環境に応じた最適な材料の選択が可能となる。
Safety of tap water as drinking water is eliminated because no organic solvent elutes into the tap water from the adhesive by using no adhesive in the manufacture of the inclined pipe unit used in the upward flow settling device At the same time, the risk of damaging the inclined pipe unit due to aging of the adhesive can also be avoided.
In addition, a material such as A-PET (polyethylene terephthalate), which has not been able to realize sufficient adhesive strength with an adhesive, has a practically no problem by using a welding method. The range of materials selection is widened, and it is possible to select the most suitable material according to the installation environment of the inclined pipe unit.
また、沈澱池の沈降装置には、水中のため荷重はかからないが、設置や点検保守時に沈降装置の上部にパネルを載せてその上を作業員が乗ることがある。このため、本願発明の傾斜管ユニットでは、角型管と平板との接合に適宜全面又は部分的溶着を採用することにより十分な溶着強度の確保が可能であり、作業員の荷重により沈降装置が座屈することはない。さらに、本願発明の傾斜管ユニットでは、現場での補修も容易に行なうことができ、作業効率，作業環境面からもすぐれた製造方法である。 In addition, the settling device in the settling pond is underwater, so no load is applied. However, a worker may get on the panel by placing a panel on top of the settling device during installation or inspection maintenance. For this reason, in the inclined pipe unit of the present invention, it is possible to ensure a sufficient welding strength by adopting a full or partial welding as appropriate for joining the square tube and the flat plate. There is no buckling. Furthermore, the inclined pipe unit of the present invention can be easily repaired on site, and is a manufacturing method that is excellent in terms of work efficiency and work environment.

傾斜管ユニットの設置にあたっては、傾斜管内でのフロックの沈降が容易になるように、ホーンで溶着させた部位が側面になるように設置する必要があり、このため、溶着は、常に水の流れの側面となる傾斜管ユニットの平板側から行う。 When installing the inclined pipe unit, it is necessary to install it so that the part welded with the horn is on the side so that the floc settles in the inclined pipe easily. This is done from the flat plate side of the inclined tube unit which is the side of the tube.
