Description

本発明は、汚水等の被処理水中の夾雑物を捕集・破砕する夾雑物処理装置に関する。   The present invention relates to a contaminant treatment apparatus that collects and crushes contaminants in water to be treated such as sewage.

空缶、プラスチック容器、木片等の夾雑物が下水（被処理水）と一緒に下水処理施設に流入すると、この下水処理施設の配管内やポンプの詰まり、破損等の事故原因となるため、従来からかかる事故を未然に防止する装置として特許文献１及び特許文献２に記載の装置が知られている。特許文献１に記載の装置は、図７に示すように、下水路中にエンドレスループ形状の開放型メッシュスクリーン２と破砕機１を組み合わせたもので、下水中の夾雑物をエンドレスループ形状の開放型メッシュスクリーン２で捕捉して、これを破砕機１へ搬入し、この破砕機１で細かく破砕して下水中に分散させるものである。   If contaminants such as empty cans, plastic containers, wood chips, etc., flow into the sewage treatment facility together with the sewage (treated water), it may cause accidents such as clogging or damage in the piping of the sewage treatment facility or the pump. Therefore, devices described in Patent Document 1 and Patent Document 2 are known as devices for preventing such accidents. As shown in FIG. 7, the device described in Patent Document 1 is a combination of an endless loop-shaped open-type mesh screen 2 and a crusher 1 in a sewage channel.

Japanese Patent Publication No. 7-85781 JP-A-8-226165

しかしながら、特許文献１に記載の装置では以下のような問題があった。略長円形状の周回軌道を移動するメッシュスクリーン２におけるスクリーン部をポリエチレン・ナイロンのような可撓性材料によって構成しているため、スクリーン部を強固なものにすることができず、スクリーン部は損傷しやすく耐久性が悪いという問題があった。また、スクリーンがエンドレスループ式であるため、スクリーンが二重になり水流抵抗を大きくし、下水の通過を妨げてしまうという問題と共に前面側を通過した夾雑物が後方側から出て行くのが難しくスクリーン部内に滞留し運転が困難になるという問題があった。また、スクリーンは網状に編み込まれたベルト面であるため、その凹凸により夾雑物が絡み付き易く、夾雑物が一旦絡み付くとほどきにくいという問題があった。   However, the apparatus described in Patent Document 1 has the following problems. Since the screen portion of the mesh screen 2 that moves in the substantially elliptical circular orbit is made of a flexible material such as polyethylene / nylon, the screen portion cannot be strengthened. There was a problem that it was easily damaged and had poor durability. In addition, since the screen is an endless loop type, the screen is doubled, the water flow resistance is increased, and the passage of sewage is hindered. There was a problem that the operation stayed in the screen and operation became difficult. Further, since the screen is a belt surface knitted in a net shape, there is a problem that impurities are easily entangled due to the unevenness, and once the impurities are entangled, it is difficult to unwind.

また、特許文献２に記載の装置では、水流が速くなるに連れて、水流の流れ方向の分力が、夾雑物をバースクリーンに沿って移動させる分力よりも過大となってしまい、夾雑物がバースクリーンに押しつけられバースクリーンに沿って移動できずに滞留するという問題があった。   Moreover, in the apparatus described in Patent Document 2, as the water flow becomes faster, the component force in the flow direction of the water flow becomes larger than the component force that moves the contaminants along the bar screen. Has been pressed against the bar screen and cannot move along the bar screen and stays there.

本発明は、このような課題を解決するために成されたものであり、スクリーン装置の耐久性の向上を図りつつ、水流抵抗を減少させて水の通りを良くすると共に、スクリーン装置に夾雑物が滞留せずに運転に支障をきたすことなく、効率的且つ確実に夾雑物を破砕機に収集可能な夾雑物処理装置を提供することを目的とする。   The present invention has been made to solve such problems, and while improving the durability of the screen device, reducing the water flow resistance and improving the passage of water, the screen device is also contaminated. An object of the present invention is to provide a contaminant processing apparatus that can efficiently and surely collect contaminants in a crusher without causing troubles in operation without stagnation.

本発明による夾雑物処理装置は、被処理水中の夾雑物を捕集するスクリーン装置と、このスクリーン装置により捕集された夾雑物を破砕する破砕機とが、水路を横断するように並設される夾雑物処理装置であって、スクリーン装置と破砕機とは互いに近接して配置され、スクリーン装置は、上下方向に複数が互いに離間して積層された円弧状スクリーン部材と、上下方向に複数が互いに離間して配置され、積層された円弧状スクリーン部材同士の間を移動するレーキと、これらのレーキを支持し上下方向に延在するレーキ軸と、を備え、破砕機は、上下方向を軸心として回転し夾雑物を破砕可能なカッタ刃を有し、このカッタ刃の周回軌道の外周縁は、円弧状スクリーン部材の外周縁に近接され、レーキ軸は、円弧状スクリーン部材の外周縁の中心と偏心して設置されることで、レーキの先端部は、円弧状スクリーン部材の外周縁から出没して円弧状スクリーン部材の外周縁とカッタ刃の周回軌道の外周縁とが近接する位置辺りで没入し、スクリーン装置に捕集された夾雑物を掻き寄せて破砕機へ収集可能とすることを特徴としている。   In the contaminant treatment apparatus according to the present invention, a screen device that collects contaminants in water to be treated and a crusher that crushes contaminants collected by the screen device are arranged side by side so as to cross the water channel. The screen processing device and the crusher are arranged close to each other. The screen device includes an arcuate screen member that is stacked in a plurality of vertical directions and a plurality of screen devices that are stacked in the vertical direction. The crusher is provided with a rake that is spaced from each other and moves between the stacked arc-shaped screen members, and a rake shaft that supports the rake and extends in the vertical direction. The cutter blade has a cutter blade that rotates as a core and can crush impurities. The outer peripheral edge of the orbit of the cutter blade is close to the outer peripheral edge of the arc-shaped screen member, and the rake axis is the outer peripheral edge of the arc-shaped screen member. By being installed eccentrically from the center, the tip of the rake will protrude from the outer periphery of the arcuate screen member at a position where the outer periphery of the arcuate screen member and the outer periphery of the circular orbit of the cutter blade are close to each other. It is characterized by being able to immerse the dust collected in the screen device and collect it in a crusher.

このように構成された夾雑物処理装置によれば、上下方向に円弧状スクリーン部材が積層され、この円弧状スクリーン部材間を移動するレーキを複数備えるレーキ軸が、この円弧状スクリーン部材の外周縁の中心と偏心して設置されているため、レーキの先端部が円弧状スクリーン部材の外周縁から出没し、円弧状スクリーン部材によって捕集された夾雑物をレーキによって掻き寄せることができる。従って、夾雑物が円弧状スクリーン部材に滞留したり、絡みついたりすることが無くされ、水流抵抗を減少させて被処理水の流れを良くすると共に夾雑物を破砕機へ確実に収集させることができる。また、円弧状スクリーン部材は、その後側が開放されているため、円弧状スクリーン部材内での夾雑物の滞留が防止される。また、水流抵抗が減少されるため、スクリーン装置に係る応力を低減させることができ、スクリーン装置の耐久性の向上を図ることができる。また、カッタ刃の周回軌道の外周縁が、円弧状スクリーン部材の外周縁に近接されると共にこの辺りでレーキの先端が円弧状スクリーン部材の外周縁から没入するため、破砕機とスクリーン装置との間から下流側へ流出する夾雑物が大幅に減らされ、夾雑物を効率的且つ確実に破砕機に収集することが可能となる。   According to the contaminant processing apparatus configured as described above, the arc-shaped screen members are stacked in the vertical direction, and the rake shaft including a plurality of rakes moving between the arc-shaped screen members is the outer peripheral edge of the arc-shaped screen member. Therefore, the tip of the rake protrudes from the outer peripheral edge of the arc-shaped screen member, and the foreign matter collected by the arc-shaped screen member can be scraped by the rake. Accordingly, it is possible to prevent the foreign matter from staying or entangled in the arc-shaped screen member, to reduce the water flow resistance and improve the flow of the water to be treated, and to reliably collect the foreign matter in the crusher. . Moreover, since the rear side of the arcuate screen member is opened, the stay of impurities in the arcuate screen member is prevented. Further, since the water flow resistance is reduced, the stress relating to the screen device can be reduced, and the durability of the screen device can be improved. Further, since the outer peripheral edge of the circular orbit of the cutter blade is close to the outer peripheral edge of the arc-shaped screen member and the tip of the rake is immersed from the outer peripheral edge of the arc-shaped screen member, the crusher and the screen device Contaminants flowing out from the space to the downstream side are greatly reduced, and the contaminants can be efficiently and reliably collected in the crusher.

ここで、円弧状スクリーン部材同士の上下方向の間隔をｔとした場合、カッタ刃の周回軌道の外周縁と円弧状スクリーン部材の外周縁との距離ｘは、３≦ｘ≦ｔ（単位はｍｍ）である構成であると、下流側に流出しても問題にならない大きさの夾雑物はスクリーン装置と破砕機との間を通過し、下流側に流出させたくない大きさの夾雑物は、スクリーン装置と破砕機との間を通過できずに、破砕機へ移送され、夾雑物の大きさによって選別することができ、効率的且つ確実に夾雑物を破砕機に収集することが可能となる。   Here, when the vertical interval between the arcuate screen members is t, the distance x between the outer peripheral edge of the circular orbit of the cutter blade and the outer peripheral edge of the arcuate screen member is 3 ≦ x ≦ t (unit: mm) ) Is a size that does not cause a problem even if it flows out downstream, passes between the screen device and the crusher, and a size that does not want to flow out downstream is Without being able to pass between the screen device and the crusher, it is transferred to the crusher and can be sorted according to the size of the contaminants, and the contaminants can be efficiently and reliably collected in the crusher. .

また、スクリーン装置は、レーキ軸と共に回転し回転するレーキが破砕機を指向する位置の手前から当該指向する位置にかけて、破砕機へ向かう被処理水の流れを形成可能な水流案内部を備える構成であると、捕集された夾雑物が円弧状スクリーン部材の外周縁から剥離し易くなり、一層効率的且つ確実に夾雑物を破砕機に収集することが可能となる。   Further, the screen device is configured to include a water flow guide portion that can form a flow of water to be treated toward the crusher from a position where the rake rotating and rotating with the rake shaft is directed to the crusher to a position directed to the crusher. If it exists, it will become easy to peel the collected foreign material from the outer periphery of an arc-shaped screen member, and it will become possible to collect a foreign material to a crusher more efficiently and reliably.

また、レーキの先端の回転速度は、カッタ刃の外周の回転速度の７０％以下であると好ましく、レーキによって掻き寄せられた夾雑物が破砕機に引き込まれ易くなり、一層効率的且つ確実に夾雑物を破砕機に収集することが可能となる。   Moreover, the rotational speed of the tip of the rake is preferably 70% or less of the rotational speed of the outer periphery of the cutter blade, and the foreign matter raked by the rake is easily drawn into the crusher, making it more efficient and reliable. Objects can be collected in a crusher.

また、レーキは弾性体から構成されていると、レーキと破砕機との間に、例えば硬い材木等の夾雑物が挟まった場合に、レーキが好適に弾性変形するため、レーキの破損の虞が無くされる。   Further, if the rake is made of an elastic body, the rake is preferably elastically deformed when a foreign object such as hard timber is sandwiched between the rake and the crusher, so that the rake may be damaged. Be lost.

本発明によれば、スクリーン装置の耐久性の向上を図りつつ、水流抵抗を減少させて水の通りを良くすると共に、スクリーン装置に夾雑物が滞留せずに運転に支障をきたすことなく、効率的且つ確実に破砕機に収集可能な夾雑物処理装置を提供することができる。   According to the present invention, while improving the durability of the screen device, the water flow resistance is reduced to improve the passage of water, and the screen device is free from impurities and does not hinder the operation. It is possible to provide a foreign matter processing apparatus that can be collected in a crusher in a reliable and reliable manner.

レーキ４６は、平板状を成し硬質ゴム等の弾性体によって構成されている。なお、レーキ４６を、その他のゴム、板バネ等の弾性体によって構成してもよい。レーキ４６の先端部は、図４に示すように、レーキ４６の回転方向に対する表側の端部の半径方向の長さが反対側の裏側の端部の半径方向より長くされた傾斜面４６ａとされている。この傾斜面４６ａの傾斜角θは、１０度〜４５度が好ましい。なお、これとは逆に、レーキ４６の回転方向に対する裏側の端部の半径方向の長さが反対側の表側の端部の半径方向より長くされた傾斜面の場合には、夾雑物が、移動するレーキの先端部で回転してしまい、夾雑物を上手く移送できなくなる。このレーキ４６は、図３〜図５に示すように、上下方向に延在する矩形状の水流案内板（水流案内部）５０に固定されている。   The rake 46 has a flat plate shape and is made of an elastic body such as hard rubber. Note that the rake 46 may be formed of other elastic bodies such as rubber and leaf springs. As shown in FIG. 4, the tip of the rake 46 has an inclined surface 46a in which the radial length of the front end with respect to the rotation direction of the rake 46 is longer than the radial direction of the opposite back end. ing. The inclination angle θ of the inclined surface 46a is preferably 10 to 45 degrees. Contrary to this, in the case of an inclined surface in which the radial length of the back end with respect to the rotation direction of the rake 46 is longer than the radial direction of the front end on the opposite side, impurities are It will rotate at the tip of the moving rake, and it will not be possible to transfer the impurities well. As shown in FIGS. 3 to 5, the rake 46 is fixed to a rectangular water flow guide plate (water flow guide portion) 50 extending in the vertical direction.

この水流案内板５０の上下方向に伸びる一方の端面には、上記複数のレーキ４６が水平方向に伸びるように、上下方向に並設されている。また、水流案内板５０は、ボルト締め用の複数の開口部５０ａを備え、図１及び図６に示すように、レーキ軸４７に固定された固定部材５１を介して、レーキ軸４７に着脱可能に固定されている。水流案内板５０は、レーキ軸４７と共に回転して、被処理水の流れ方向を変更可能とするものであり、回転するレーキ４６が破砕機３０を指向する位置の手前から当該指向する位置にかけて、破砕機３０へ向かう被処理水の流れを形成し、捕集された夾雑物を円弧状スクリーン部材４５の外周縁から剥離し易くさせるものである。この水流案内板５０は、平面視において、円周方向に等間隔（本実施形態では、９０度）で配置されている。このため、被処理水による抵抗を分散して、均一化することができる（詳しくは後述）。なお、最上段の水流案内板５０は、図３に示すように、９串（本）のレーキ４６を備え、その他の水流案内板５０は、１１串（本）のレーキ４６を備えている。この最上段の水流案内板５０の串数を変更することで、水路高さの異なる各種水路に対する適用が可能とされている。   On one end surface of the water flow guide plate 50 extending in the vertical direction, the plurality of rakes 46 are juxtaposed in the vertical direction so as to extend in the horizontal direction. Further, the water flow guide plate 50 is provided with a plurality of bolting openings 50a and can be attached to and detached from the rake shaft 47 via a fixing member 51 fixed to the rake shaft 47 as shown in FIGS. It is fixed to. The water flow guide plate 50 is rotated together with the rake shaft 47 to change the flow direction of the water to be treated. From the position before the position where the rotating rake 46 is directed to the crusher 30 to the position where the direction is directed, The flow of the to-be-processed water which goes to the crusher 30 is formed, and the collected foreign substance is made easy to peel from the outer periphery of the arc-shaped screen member 45. FIG. The water flow guide plates 50 are arranged at equal intervals (90 degrees in the present embodiment) in the circumferential direction in plan view. For this reason, the resistance by the water to be treated can be dispersed and made uniform (details will be described later). As shown in FIG. 3, the uppermost water flow guide plate 50 includes nine skewers (books) of rakes 46, and the other water flow guide plate 50 includes eleven skewers (books) of rakes 46. By changing the number of skewers of the uppermost water flow guide plate 50, application to various water channels having different water channel heights is possible.

固定部材５１は、図６に示すように、軸方向に分割された半割円筒対５２，５３を備え、その側面には、上下方向に延在し、水流案内板５０を固定するための板状の固定片５４が複数突設されている（なお、図６では、そのうちの一つのみを記載している）。この固定片５４は、円周方向に９０度等配で配置されている。また、固定片５４には、水流案内板５０の開口部５０ａに対応する位置に開口部５４ａが形成され、これらの開口部５０ａ，５４ａには、図１に示すように、ボルト５５が挿通されて、水流案内板５０及び固定部材５１が互いに連結されている。   As shown in FIG. 6, the fixing member 51 includes a pair of halved cylinders 52 and 53 that are divided in the axial direction. A plurality of fixed pieces 54 are formed in a protruding manner (note that only one of them is shown in FIG. 6). The fixed pieces 54 are arranged at an equal angle of 90 degrees in the circumferential direction. Further, the fixed piece 54 is formed with an opening 54a at a position corresponding to the opening 50a of the water flow guide plate 50, and a bolt 55 is inserted into these openings 50a and 54a as shown in FIG. Thus, the water flow guide plate 50 and the fixing member 51 are connected to each other.

レーキ軸４７は、図３に示すように、その両端部が軸受け５６，５７によって支承され、下端側の軸受け５６は、最下段の円弧状スクリーン部材４５に連結され、上端側の軸受け５７は、最上段の円弧状スクリーン部材４５に連結されて、レーキ軸４７は、円弧状スクリーン部材４５の外周縁の中心４５ｏ（図１参照）と偏心する位置に配置されている。すなわち、レーキ軸４７は、円弧状スクリーン部材４５の外周縁の中心４５ｏと偏心して設置されることで、回転するレーキ４６の先端部は、円弧状スクリーン部材４５の外周縁から出没して円弧状スクリーン部材４５の外周縁と回転破砕刃３２の周回軌道の外周縁とが近接する位置辺りで没入し、スクリーン装置４０に捕集された夾雑物を掻き寄せて破砕機３０へ収集可能とされている。因みに、本実施形態では、回転破砕刃３２の周回軌道の外周縁と円弧状スクリーン部材４５の外周縁との距離ｘは、約７ｍｍとされている。そして、これら円弧状スクリーン部材４５、レーキ４６、レーキ軸４７、水流案内板５０等を有するスクリーン装置４０は、その下部に、上記据付枠９０の位置決めピンに嵌合する位置決め孔（不図示）を備えている。   As shown in FIG. 3, the rake shaft 47 is supported at both ends by bearings 56, 57, the lower end side bearing 56 is connected to the lowermost arc-shaped screen member 45, and the upper end side bearing 57 is Connected to the uppermost arcuate screen member 45, the rake shaft 47 is arranged at a position eccentric to the center 45 o (see FIG. 1) of the outer peripheral edge of the arcuate screen member 45. That is, the rake shaft 47 is installed eccentrically with the center 45o of the outer peripheral edge of the arc-shaped screen member 45, so that the leading end of the rotating rake 46 protrudes from the outer peripheral edge of the arc-shaped screen member 45 and is arc-shaped. The outer peripheral edge of the screen member 45 and the outer peripheral edge of the circular orbit of the rotary crushing blade 32 are immersed near each other, and the foreign matter collected by the screen device 40 is scraped and collected into the crusher 30. Yes. Incidentally, in this embodiment, the distance x between the outer peripheral edge of the orbit of the rotary crushing blade 32 and the outer peripheral edge of the arcuate screen member 45 is about 7 mm. The screen device 40 having the arcuate screen member 45, the rake 46, the rake shaft 47, the water flow guide plate 50, and the like has a positioning hole (not shown) fitted in the positioning pin of the installation frame 90 at the lower part thereof. I have.

次に、夾雑物処理装置１００を設置する方法について説明する。先ず、据付枠９０を水路１０の所定の位置に固定する。次に、スクリーン装置４０に設けられた位置決め孔に、据付枠９０の位置決めピンを嵌合して、スクリーン装置４０の位置決めを行う。また、破砕機３０のウエッジライナー３６〜３８を、据付枠９０のウエッジライナー９１〜９３に対面するように、上方から吊り下ろすことにより、破砕機３０の位置決めを行う。このようにして、破砕機３０及びスクリーン装置４０を据付枠９０の所定の位置に配置し、夾雑物処理装置１００を水路１０に設置する。なお、据付枠９０にスクリーン装置４０、破砕機３０を各々固定した後に、この据付枠９０を吊り下ろして水路１０に設置するようにしてもよい。   Next, a method for installing the foreign matter processing apparatus 100 will be described. First, the installation frame 90 is fixed at a predetermined position in the water channel 10. Next, the positioning pin of the installation frame 90 is fitted into the positioning hole provided in the screen device 40 to position the screen device 40. Further, the crusher 30 is positioned by hanging the wedge liners 36 to 38 of the crusher 30 from above so as to face the wedge liners 91 to 93 of the installation frame 90. In this way, the crusher 30 and the screen device 40 are arranged at predetermined positions of the installation frame 90, and the contaminant processing device 100 is installed in the water channel 10. In addition, after fixing the screen apparatus 40 and the crusher 30 to the installation frame 90, the installation frame 90 may be suspended and installed in the water channel 10.

このように構成された夾雑物処理装置１００では、縦型電動機によって、破砕機３０の回転破砕刃３２，３２が駆動され、平面視において、スクリーン装置４０側（図示左側）の回転破砕刃３２は、右回りに回転し、側壁１０ｃ側（図示右側）の回転破砕刃３２は、左回りに回転する。また、縦型電動機４８によって、スクリーン装置４０のレーキ軸４７が駆動され、水流案内板５０及びレーキ４６が、平面視において、右回りに回転する。なお、レーキ４６の先端の回転速度は、回転破砕刃３２，３２の外周の回転速度の７０％以下としている。また、破砕機３０、スクリーン装置４０は、縦型電動機を個別に備えているため、過負荷時の噛み込み反転動作を、破砕機３０、スクリーン装置４０でそれぞれ個別に行うことができる。   In the contaminant processing apparatus 100 configured in this manner, the rotary crushing blades 32 and 32 of the crusher 30 are driven by the vertical electric motor, and the rotary crushing blade 32 on the screen device 40 side (the left side in the drawing) is viewed in plan view. The rotating crushing blade 32 on the side wall 10c side (the right side in the drawing) rotates counterclockwise. Further, the rake shaft 47 of the screen device 40 is driven by the vertical motor 48, and the water flow guide plate 50 and the rake 46 rotate clockwise in plan view. The rotational speed of the tip of the rake 46 is 70% or less of the rotational speed of the outer periphery of the rotary crushing blades 32, 32. Further, since the crusher 30 and the screen device 40 are individually provided with the vertical electric motor, the biting and reversing operation at the time of overload can be individually performed by the crusher 30 and the screen device 40, respectively.

ここで、レーキ軸４７は、円弧状スクリーン部材４５の中心４５ｏと偏心されて設置されているため、レーキ４６の先端部は、平面視において、円弧状スクリーン部材４５の外周縁の前面左側から外方に出現し、円弧状スクリーン部材４５の外周縁の前面、右側面において、円弧状スクリーン部材４５外を通過し、円弧状スクリーン部材４５の外周縁の右側面後側で円弧状スクリーン部材４５内に没入する。そして、被処理水中の夾雑物は、スクリーン装置４０の円弧状スクリーン部材４５によって捕集され、この円弧状スクリーン部材４５により捕集された夾雑物は、円弧状スクリーン部材４５の外周縁から突き出したレーキ４６の先端部によって、掻き寄せられ破砕機３０に移送される。また、水流案内板５０が、レーキ軸４７と共に回転しレーキ４６が破砕機３０を指向する位置の手前から当該指向する位置にかけて、破砕機３０へ向かう被処理水の流れを形成するため、捕集された夾雑物が円弧状スクリーン部材４５の外周縁から剥離し易くなり、容易に破砕機３０へ移送される。   Here, since the rake shaft 47 is installed eccentrically with the center 45o of the arcuate screen member 45, the tip of the rake 46 is outside the front left side of the outer periphery of the arcuate screen member 45 in plan view. The arcuate screen member 45 passes outside the arcuate screen member 45 on the front and right sides of the outer peripheral edge of the arcuate screen member 45, and enters the arcuate screen member 45 on the rear side of the right side of the outer peripheral edge of the arcuate screen member 45. Immerse yourself in. The contaminants in the water to be treated are collected by the arc-shaped screen member 45 of the screen device 40, and the contaminants collected by the arc-shaped screen member 45 protrude from the outer peripheral edge of the arc-shaped screen member 45. The tip of the rake 46 is scraped and transferred to the crusher 30. Further, since the water flow guide plate 50 rotates together with the rake shaft 47 and forms a flow of water to be treated toward the crusher 30 from a position before the position where the rake 46 is directed to the crusher 30 to a position where the rake 46 is directed. The contaminated foreign matter is easily peeled off from the outer peripheral edge of the arc-shaped screen member 45 and is easily transferred to the crusher 30.

このように夾雑物処理装置１００によれば、夾雑物が円弧状スクリーン部材４５に滞留したり、絡みついたりすることが無くされ、水流抵抗を減少させて被処理水の流れを良くすると共に夾雑物を破砕機３０へ確実に収集させることができる。また、円弧状スクリーン部材４５は、その後側が開放されているため、円弧状スクリーン部材４５内での夾雑物の滞留が防止され、運転に支障をきたすことが防止されている。また、水流抵抗が減少されるため、スクリーン装置４０に係る応力を低減させることができ、スクリーン装置４０の耐久性の向上を図ることができる。また、回転破砕刃３２の周回軌道の外周縁が、円弧状スクリーン部材４５の外周縁に近接されると共にこの辺りでレーキ４６の先端が円弧状スクリーン部材４５の外周縁から没入するため、破砕機３０とスクリーン装置４０との間から下流側へ流出する夾雑物が大幅に減らされ、夾雑物を効率的且つ確実に破砕機３０に収集することが可能となる。   As described above, according to the contaminant processing apparatus 100, the contaminants are not retained or entangled in the arc-shaped screen member 45, and the water flow resistance is reduced to improve the flow of water to be treated and the contaminants. Can be reliably collected in the crusher 30. Further, since the rear side of the arc-shaped screen member 45 is opened, it is possible to prevent the foreign matter from staying in the arc-shaped screen member 45 and preventing the operation from being hindered. Further, since the water flow resistance is reduced, the stress relating to the screen device 40 can be reduced, and the durability of the screen device 40 can be improved. Further, since the outer peripheral edge of the circular orbit of the rotary crushing blade 32 is brought close to the outer peripheral edge of the arcuate screen member 45 and the tip of the rake 46 is immersed from the outer peripheral edge of the arcuate screen member 45 around this, the crusher The contaminants flowing out from between the screen 30 and the screen device 40 to the downstream side are greatly reduced, and the contaminants can be collected in the crusher 30 efficiently and reliably.

また、円弧状スクリーン部材４５同士の上下方向の間隔をｔ（ｔ＝１６）とし、回転破砕刃３２の周回軌道の外周縁と円弧状スクリーン部材４５の外周縁との距離ｘ（ｘ＝７）は、３≦ｘ≦ｔ（単位はｍｍ）の関係を満たし、下流側に流出しても問題にならない大きさの夾雑物はスクリーン装置４５と破砕機３０との間を通過し、下流側に流出させたくない大きさの夾雑物は、スクリーン装置４５と破砕機３０との間を通過できずに、破砕機３０へ移送され、夾雑物の大きさによって選別することができ、効率的且つ確実に夾雑物を破砕機３０に収集することが可能とされている。なお、回転破砕刃３２の周回軌道の外周縁と円弧状スクリーン部材４５の外周縁との距離は、製作誤差等を考慮して３ｍｍ以上とすることが必要である。   Further, the distance in the vertical direction between the arcuate screen members 45 is t (t = 16), and the distance x (x = 7) between the outer peripheral edge of the circular orbit of the rotary crushing blade 32 and the outer peripheral edge of the arcuate screen member 45. Satisfies the relationship of 3 ≦ x ≦ t (unit: mm), and foreign matter of a size that does not cause a problem even if it flows out to the downstream side passes between the screen device 45 and the crusher 30, Contaminants of a size that you do not want to flow out cannot pass between the screen device 45 and the crusher 30, but are transferred to the crusher 30 and can be sorted according to the size of the contaminants. In addition, it is possible to collect impurities in the crusher 30. Note that the distance between the outer peripheral edge of the circular orbit of the rotary crushing blade 32 and the outer peripheral edge of the arcuate screen member 45 needs to be 3 mm or more in consideration of manufacturing errors and the like.

また、スクリーン装置４０は、水流案内板５０を備えているため、捕集された夾雑物が円弧状スクリーン部材４５の外周縁から剥離し易くなり、一層効率的且つ確実に夾雑物を破砕機３０に収集することができる。   Further, since the screen device 40 includes the water flow guide plate 50, the collected contaminants are easily peeled off from the outer peripheral edge of the arc-shaped screen member 45, and the contaminants are more efficiently and reliably broken. Can be collected.

また、レーキ４６の先端の回転速度は、回転破砕刃３２の外周の回転速度の７０％以下であるため、レーキ４６によって掻き寄せられた夾雑物が破砕機３０に引き込まれ易くなり、一層効率的且つ確実に夾雑物を破砕機３０に収集することができる。因みに、これは本発明者の実験により確認されている。   Further, since the rotation speed of the tip of the rake 46 is 70% or less of the rotation speed of the outer periphery of the rotary crushing blade 32, the foreign matter scraped by the rake 46 is easily drawn into the crusher 30 and is more efficient. In addition, impurities can be reliably collected in the crusher 30. Incidentally, this has been confirmed by the inventors' experiments.

また、レーキ４６は弾性体から構成されているため、レーキ４６と破砕機３０との間に、例えば硬い木材等の夾雑物が挟まった場合に、レーキ４６が好適に弾性変形するため、レーキ４６の破損の虞が無くされる。   In addition, since the rake 46 is made of an elastic body, the rake 46 is preferably elastically deformed when a foreign object such as hard wood is sandwiched between the rake 46 and the crusher 30, so that the rake 46 is suitably deformed. There is no risk of damage.

また、水流案内板５０は周方向に等間隔で配置されているため、周方向における一のレーキ（上下方向に並ぶレーキ群）４６には水流に対向し回転を妨げようとする抵抗が作用するが、一のレーキ４６の反対側の方にある他のレーキ４６には水流により回転を促進しようとする力が作用し、各レーキ４６に係る水流抵抗が好適に分散されるため、レーキ軸４７の回転動力を抑えることが可能となり省エネ化が図られている。なお、レーキ（上下方向に並ぶレーキ群）４６は、周方向に４等配に限定されず、２等配、３等配でもよく、５等配以上であってもよい。   Further, since the water flow guide plates 50 are arranged at equal intervals in the circumferential direction, a resistance that opposes the water flow and prevents rotation is applied to one rake (rake group arranged in the vertical direction) 46 in the circumferential direction. However, a force to promote rotation by the water flow acts on the other rake 46 on the opposite side of the one rake 46, and the water flow resistance related to each rake 46 is preferably dispersed. This makes it possible to reduce the rotational power of the machine and save energy. Note that the rakes (the rake groups arranged in the vertical direction) 46 are not limited to four equals in the circumferential direction, and may be two equals, three equals, or five or more equals.

なお、円弧状スクリーン部材４５を、プラスチックによって形成することで、軽量化を図ることができると共に、低ひずみとすることができる。   In addition, by forming the arc-shaped screen member 45 from plastic, the weight can be reduced and the strain can be reduced.
