この考案は、下水処理場等に設置されるし渣脱水機の目詰り除去装置の改良に 関する。 The present invention relates to improvement of a clogging removal device for a residue dehydrator installed in a sewage treatment plant or the like.
【０００２】[0002]
下水処理場等で発生するし渣の脱水機は公知である。実開平３−４７６８８号 考案、実公昭５６−１０４７５号考案はその例である。実開平３−４７６８８号 考案では、し渣の脱水を行うための円筒スクリーンをウェッジワイヤー状の棒材 をその軸線方向に配列して構成しており、また、実公昭５６−１０４７５号考案 では、長尺の洗浄筒にドラムスクリーンを継足して、その軸心部に送り軸を支架 している。そして、洗浄筒内で洗浄したし渣を脱水するようにし、ドラムスクリ ーン内における送り軸の螺旋翼の外周には、レーキを設けてドラムスクリーンの 目を清掃するようにしている。 A dehydrator of a residue generated in a sewage treatment plant is known. Examples are the invention of the Kaikaihei 3-47688 and the utility model of Sho 56-10475. In the invention of Japanese Utility Model Laid-Open No. 3-47688, a cylindrical screen for dehydrating residue is constructed by arranging wedge-wire-shaped rods in the axial direction, and in Japanese Utility Model Publication No. 56-10475, A drum screen is added to a long cleaning cylinder, and the feed shaft is supported at the center of the drum screen. Then, the residue washed in the cleaning cylinder is dehydrated, and a rake is provided on the outer periphery of the spiral blade of the feed shaft in the drum screen to clean the eyes of the drum screen.
【０００３】[0003]
然しながら、実開平３−４７６８８号考案では、円筒スクリーンを構成するウ ェッジワイヤーが、その軸線方向に向けて配列してあるので、目詰りした時に目 詰物を除去し難く、また、実公昭５６−１０４７５号考案では、ドラムスクリー ンの前段に洗浄筒を設けているので、機長が長くなり設置面積を占めるとともに 、原水中の水分を切ったのち、別途洗浄水で夾雑物を洗うので大量の洗浄水を必 要とする。また、この考案のようにレーキを設けるとすれば、多数のレーキを必 要とし、これを螺旋翼の刃縁につけるには手数を要する。 However, in the invention of Japanese Utility Model Laid-Open No. 3-47688, since the wedge wires that form the cylindrical screen are arranged in the axial direction, it is difficult to remove the clogs when they are clogged. Since the washing cylinder is installed in the previous stage of the drum screen in the No. device, the captain becomes long and occupies the installation area, and after removing the water in the raw water, foreign matters are washed separately with a large amount of washing water. Is required. Further, if the rake is provided as in this invention, a large number of rakes are required, and it takes time to attach the rakes to the blade edge of the spiral blade.
【０００４】[0004]
この考案は、上述のような従来の課題を解決したものであって、その要旨とす るところは、ドラム状に構成したスクリーン内に螺旋翼を巻き回した送り軸を支 架し、スクリーンの一端に供給された原水を他端に向かって搬送し、原水中のし 渣を分離洗浄するようにしたし渣脱水機において、上記スクリーンの始端部をト ラフ状に構成し、このトラフ状のスクリーンのスリット目に係合する櫛歯状のス クレーパーを上記螺旋翼の外周部に設けたものである。 This invention solves the above-mentioned conventional problems, and the gist of the invention is to mount a feed shaft around which a spiral blade is wound inside a screen configured in a drum shape, and The raw water supplied to one end is conveyed to the other end to separate and wash the residual water in the raw water, and the starting end of the screen is configured in the form of a trough. A comb tooth-shaped scraper that engages with the slits of the screen is provided on the outer peripheral portion of the spiral blade.

この考案に係る装置は、上述のように構成してあり、供給槽から流下する原水 中のし渣は、スクリーンによって捕捉され、送り軸の回転に伴って螺旋翼によっ てスクリーンの他端に向かって送られる。そして、このとき、水を切られた夾雑 物は、スクリーンの目に詰まらんとするが、この考案では螺旋翼の外周に設けた 櫛歯状のスクレーパーがスクリーンの各目に嵌合して回転するので夾雑物を掻き 上げて搬送し、効率のよいろ過作業をなすことができる。また、この考案では、 原液を直接スクリーン上に流下させ、し渣の稀薄な原液段階で分離するので分離 し易く、然も、スクリーンの目詰りがなく分離効率が良好なものである。また、 原水を洗浄に利用するので大型の洗浄装置は必要とせず、機体も短尺小型となり 、安価に製作することができる。以下、図面に基づいてこの考案を具体的に説明 する。 The device according to the present invention is configured as described above, and the screen residue in the raw water flowing down from the supply tank is captured by the screen, and is rotated by the spiral blade to the other end of the screen as the feed shaft rotates. Sent to you. At this time, the dewatered contaminants will not clog the eyes of the screen. Therefore, contaminants can be scraped up and transported, and efficient filtration work can be performed. Further, in this invention, the stock solution is made to flow down directly onto the screen and is separated at the stage where the residue is diluted, so that the separation is easy, and the screen is not clogged and the separation efficiency is good. In addition, since raw water is used for cleaning, a large-scale cleaning device is not required, the machine body becomes short and small, and it can be manufactured at low cost. The present invention will be specifically described below with reference to the drawings.

図１は、この考案に係る装置の全体図で縦断側面図としており、図２はその原 水供給部分の斜面図である。図中、符号１は原水の供給槽、２はその下方に設け たスクリーンで図３〜図５に示すように断面が四角状の線材をトラフ状に多数並 列して構成している。そして、そのトラフ状のスクリーン２内には、図４に示す ように螺旋翼３を有する送り軸４を支架している。次に、図４および図５におい て、符号５は上記螺旋翼３の外周部に取り付けた櫛歯状のスクレーパーであって 、その個々の櫛歯５ａは図５に示すように前述のスクリーン２の目２ａに嵌合さ せてあり、螺旋翼３の回転に伴って目２ａに沿って摺動回転するようにしてある 。尚、符号５ｂは櫛歯５ａの取付バー、２ｂはスクリーン２の補強バーである。 尚、図１および図２において、符号６は、夾雑物の排出管、７は原水の流入管、 ８は処理水槽、９はダンパーである。 FIG. 1 is an overall side view of a device according to the present invention, which is a vertical side view, and FIG. 2 is a perspective view of a raw water supply part thereof. In the figure, reference numeral 1 is a raw water supply tank, 2 is a screen provided below the raw water supply tank, and as shown in FIGS. 3 to 5, a large number of square wire rods are arranged in a trough shape. In addition, as shown in FIG. 4, a feed shaft 4 having spiral blades 3 is supported in the trough-shaped screen 2. Next, in FIGS. 4 and 5, reference numeral 5 is a comb tooth-shaped scraper attached to the outer peripheral portion of the spiral blade 3, and each comb tooth 5a has the above-mentioned screen 2 as shown in FIG. It is fitted in the eye 2a and is adapted to slide and rotate along the eye 2a as the spiral blade 3 rotates. Reference numeral 5b is a mounting bar for the comb teeth 5a, and 2b is a reinforcing bar for the screen 2. In FIGS. 1 and 2, reference numeral 6 is a contaminant discharge pipe, 7 is a raw water inflow pipe, 8 is a treated water tank, and 9 is a damper.
【０００７】 この考案に係る装置は上述のように構成してあり、供給槽１から落下する原水 は、スクリーン２によって急速にろ過され、分離水は下方に設けた処理水槽８で 受け止められて機外に排出され、スクリーン２上に捕捉された夾雑物（し渣）は 、同時に回転している送り軸４の螺旋翼３によって排出管６に向かって送られ、 ダンパー９の存在によってさらに脱水されたのち、機外に取り出される。The apparatus according to the present invention is configured as described above, the raw water falling from the supply tank 1 is rapidly filtered by the screen 2, and the separated water is received by the treated water tank 8 provided below. The contaminants (stains) discharged to the outside and captured on the screen 2 are sent toward the discharge pipe 6 by the spiral blades 3 of the feed shaft 4 which are rotating at the same time, and are further dehydrated by the presence of the damper 9. After that, it is taken out of the plane.
【０００８】 この原水中のし渣の分離脱水時に、この考案では、スクリーン２の各目２ａに スクレーパー５の櫛歯５ａが嵌合してその各目２ａ内を摺動するので、スクリー ン２の底部に溜まらんとする夾雑物を掻き上げるとともに、各目２ａに詰まらん とする夾雑物を除去し、常に、効率のよい分離脱水をなすことができる。In this invention, the comb teeth 5a of the scraper 5 are fitted into the eyes 2a of the screen 2 and slide in the eyes 2a during separation and dewatering of the residue in the raw water. It is possible to scrape off the contaminants that accumulate on the bottom of the tray and remove the contaminants that accumulate on each eye 2a, so that efficient separation and dehydration can always be performed.
【０００９】 また、この考案では、スクリーン２の始端上方に供給槽１を設け、スクリーン ２上に直接原水を落下させるようにしたので、原水の供給と同時に夾雑物（し渣 ）およびスクリーン２を洗浄することができ、上述のスクレーパー５による夾雑 物の除去と相侯って効率のよい脱水をなすことができる。さらに、この考案では 、原水で夾雑物およびスクリーン５を洗うようにしたので短尺の機長で足り、設 置面積を占めない利点を有する。Further, in this invention, since the feed tank 1 is provided above the starting end of the screen 2 and the raw water is dropped directly onto the screen 2, the raw water is supplied, and at the same time, the contaminants and the screen 2 are supplied. It can be washed, and in combination with the removal of impurities by the scraper 5 described above, efficient dehydration can be performed. Further, in the present invention, the contaminants and the screen 5 are washed with raw water, so that a short captain is sufficient and the installation area is not occupied.
【００１０】[0010]
このように、この考案は、原水で夾雑物を洗うと同時に、螺旋翼３に設けたス クレーパー５でスクリーン２を完全に清掃することによって高効率の脱水を可能 にしたものであり、さらに、機長を短縮して設置面積を占めない等、従来のこの 種脱水機の課題を悉く解消し得たものである。 Thus, the present invention enables highly efficient dehydration by washing the screen 2 with the scraper 5 provided on the spiral blade 3 at the same time as washing the foreign matters with the raw water. The machine length was shortened so that the installation area was not occupied, and the problems of the conventional dehydrator of this kind could be solved completely.
