本考案は、原水または廃水に含まれているコロイドなどの凝集を生じさせる攪 拌装置に係り、本装置は、上水道、工業用水の浄化、下水道、工場廃水、工事用 排水の処理や湿式精練などに利用できる他、凝集剤を注入した後、直ちに急速な 攪拌を与える混和装置としても利用でき、本考案において攪拌装置とは、これら の装置をも包含するものである。 This invention is an agitator that causes aggregation of colloids contained in raw water or wastewater. Regarding the stirring device, this device is used for water supply, industrial water purification, sewerage, factory wastewater, construction use. It can be used for wastewater treatment, wet scouring, etc., and can be used for rapid rapid treatment immediately after injecting a flocculant. It can also be used as a mixing device that provides stirring, and in this invention, the stirring device refers to these devices. This also includes devices such as:
【０００２】0002
水中のコロイド粒子は通常負に帯電しており、この負電荷を凝集剤のもつ正荷 電により中和し、粒子を相互に結合させることを凝集といい、化学的作用、静電 気的作用、物理的作用が相互に関連して、微小なフロックができる。 この物理的作用をひきおこす方式としては、大きく分けて外部から機械的エネ ルギを与える方式と、水流自体がもつ流体エネルキ゛による方式とがある。 このうち機械的エネルギを与えるものには、パト゛ル式のフラッシュミキサな どによるものがある。しかしながらこの方式は、回転軸付近の攪拌強度が非常に 小さくなる点、軸受が水中にあるため維持管理が困難である点などの難点があり 、近時敬遠されがちである。 Colloidal particles in water are normally negatively charged, and this negative charge is transferred to the positive charge of the flocculant. The process of neutralization and bonding of particles with each other is called agglomeration, which is caused by chemical action, electrostatic Microscopic flocs are formed due to the interaction of gas and physical effects. Broadly speaking, there are two ways to bring about this physical effect: mechanical energy is applied externally. There are two methods: one that provides energy, and the other that relies on the fluid energy of the water flow itself. Among these, those that give mechanical energy include a patrol type flash mixer. It depends on what. However, with this method, the stirring intensity near the rotating shaft is extremely high. There are disadvantages such as being small and difficult to maintain because the bearings are underwater. , which tends to be avoided these days.
【０００３】 一方、水流自体がもつ流体エネルキ゛による方式は、水中に機械部分がなく維 持管理が容易である点で、機械的エネルギを与える方式より有利である。この方 式には、上下迂流式、水平迂流式及びこれら両者の複合式がある。 このうち上下迂流式とは、上下方向に水流の流れをかえる方式であって、上端 部が自由表面よりも上方にあり下端部が水路底面よりも上方にある第一の阻流壁 と、上端部が自由表面よりも下方にあり下端部が水路底面に連結された第二の阻 流壁とを、深い水路の内側壁と一体に形成し、しかもこれらの阻流壁を水流方向 に沿って互い違いになるように配置してなり、水流が第一の阻流壁の下端部や第 二の阻流壁の上端部をくぐり抜け、上下方向に流れをかえる際に乱流を生じせし めて、攪拌するというものである。 また、水平迂流式とは、左右方向に水流の流れをかえる方式であって、左端部 が水路内側面に一体に連結され右端部が水路内側面よりも中央側にある第一の阻 流壁の下端部と、右端部が水路内側面に一体に連結され左端部が水路内側面より も中央側にある第二の阻流壁の下端部とを、幅広の水路の底面と一体に形成し、 しかもこれらの阻流壁を水流方向に沿って互い違いになるように配置してなり、 水流が第一の阻流壁の右端部や第二の阻流壁の左端部をくぐり抜け、左右方向に 流れをかえる際に乱流を生じせしめて、攪拌するというものである。0003 On the other hand, the method that relies on the fluid energy of the water flow itself has no mechanical parts in the water and can be easily maintained. It is advantageous over methods that apply mechanical energy in that it is easier to maintain and manage. This person Types include vertical detour type, horizontal detour type, and a combination of these two types. Among these, the up-and-down detour type is a method that changes the flow of water in the up-down direction. a first baffle wall whose lower end is above the free surface and whose lower end is above the bottom of the waterway; and a second barrier whose upper end is below the free surface and whose lower end is connected to the bottom of the waterway. The flow walls are formed integrally with the inner wall of the deep channel, and these baffle walls are aligned in the water flow direction. The water flow is arranged alternately along the lower end of the first baffle wall and the It passes through the upper end of the second baffle wall and creates turbulence when the flow changes in the vertical direction. Mix and stir. In addition, the horizontal detour type is a method that changes the flow of water in the left and right direction, and the left end is integrally connected to the inner surface of the waterway, and the right end is located closer to the center than the inner surface of the waterway. The lower end and right end of the flow wall are integrally connected to the inner surface of the waterway, and the left end is connected to the inner surface of the waterway. The lower end of the second baffle wall on the center side is formed integrally with the bottom of the wide waterway, Moreover, these baffle walls are arranged alternately along the water flow direction, The water flow passes through the right end of the first baffle wall and the left end of the second baffle wall, and flows in the left and right direction. When changing the flow, turbulence is created to create agitation.
【０００４】 しかしながら、これらの迂流方式にも、次に述べるような欠点がある。 まず、迂流方式による攪拌エネルギは、流速の３乗に比例する。したがって、 流速が少なくなると極端に攪拌が不十分になり、流速が増えると場合によっては せっかく形成されているフロックを破壊するようになる。また、水温、水質、コ ロイドの性状など変化によっても、必要な攪拌強度は変化する。 ここで、一般に阻流壁はコンクリートの打設などにより水路内面と一体に形成 されているため、事実上上記変化に応じて攪拌強度を調整することが不可能なこ とが多い。また、相隣る阻流壁間の間隔や流路断面を変更するなどの工夫もされ ているが、たかだか極めて限られた段階で調整できる程度であって柔軟に調整す ることができない。さらに、通水時にこの調整を行なうのは流水に接して作業が 危険かつ困難であるし、入水を止め水路を干して行なうと水処理に支障を来すと いう問題がある。 また、上述の迂流方式のうち上下迂流式によると、通水及び排水の作業時に、 特に水路底面付近に大きな水圧がかかり、上述の、下端部が水路底面に連結され た第二の阻流壁は、その下端部が水路底面と一体形成され、この水圧にたえねば ならず、高剛性が要求される。したがって、水路内側面と一体に、例えば鉄筋コ ンクリートなどにより重量大に形成せざるを得ない。 したがって、一旦設置した後に上記のように相隣る阻流壁間の間隔や流路断面 を変更するなどの調整を行なうことは極めて困難である。 加えて、前記第二の阻流壁の下端部は、水路底面と一体形成されているので、 水路内の水や堆積物を排除しようとしても、該下端部に阻まれて極めて困難であ る。 一方、上述の迂流方式のうち水平迂流式によると、フロックが沈澱しない流速 にすべく、水路断面、水深を小とし、しかも滞流時間を確保しなければならない ため、広大な面積を要する問題がある。0004 However, these detour methods also have drawbacks as described below. First, the stirring energy by the bypass flow method is proportional to the cube of the flow velocity. therefore, If the flow rate decreases, stirring will become extremely insufficient, and if the flow rate increases, in some cases It begins to destroy the flocs that have been formed. In addition, water temperature, water quality, The required stirring strength also changes depending on changes in the properties of the roid. Here, the baffle wall is generally formed integrally with the inner surface of the waterway by pouring concrete, etc. Therefore, it is virtually impossible to adjust the stirring intensity according to the above changes. There are many. In addition, efforts have been made to change the spacing between adjacent baffle walls and the cross section of the flow path. However, it can only be adjusted at a very limited level and should not be adjusted flexibly. I can't do it. Furthermore, making this adjustment when water is flowing requires work in contact with running water. It is dangerous and difficult, and if we stop the water from entering and dry the waterway, it will interfere with water treatment. There is a problem. In addition, according to the upper and lower detour method among the above-mentioned detour methods, during water flow and drainage work, In particular, large water pressure is applied near the bottom of the waterway, and as mentioned above, the lower end is connected to the bottom of the waterway. The second baffle wall, whose lower end is integrally formed with the bottom of the waterway, must withstand this water pressure. Therefore, high rigidity is required. Therefore, for example, the reinforcing steel It has no choice but to be made heavy due to concrete, etc. Therefore, once installed, the spacing between adjacent baffle walls and the cross section of the flow path as described above It is extremely difficult to make adjustments such as changing the In addition, since the lower end of the second baffle wall is integrally formed with the bottom surface of the waterway, Even if you try to remove water and sediment from the waterway, it will be extremely difficult as it will be blocked by the lower end. Ru. On the other hand, according to the horizontal detour method among the detour methods mentioned above, the flow velocity is such that the flocs do not settle. In order to achieve this, the waterway cross section and water depth must be made small, and the residence time must be ensured. Therefore, there is a problem that a vast area is required.

上述の目的を達成するため本考案は、攪拌装置において 水路の内面に設けた支持枠に複数の阻流板を着脱自在に支持してなり、前記阻 流板には通水孔が多数穿設され、各々の該阻流板はその開度が流れ方向下流側が 上流側よりも大となるように配置するという技術と、 前記阻流板には、該阻流板の通水孔に符合する通水孔が設けられた調整板が摺 動自在に重合されているという技術とをもって構成される。 In order to achieve the above-mentioned purpose, the present invention uses a stirring device in which A plurality of baffle plates are removably supported on a support frame provided on the inner surface of the waterway. A large number of water passage holes are bored in the flow plate, and the opening degree of each baffle plate is such that the downstream side in the flow direction is The technique of arranging it so that it is larger than the upstream side, The baffle plate is provided with an adjustment plate that is provided with a water passage hole that matches the water passage hole of the baffle plate. It is constructed using a technology that allows it to be polymerized in a freely movable manner.

本考案の実施例を図面を参照して説明する。図中矢印は流れ方向を示す。 図１ないし図４は、本考案の上下迂流式による例を示す。 図１に示す阻流板１には、複数の通水孔１ａが板厚方向に穿設され、この通水 孔１ａを水が通過する際に生ずる水位差により、流速即ち攪拌強度を調節するも のである。この通水孔１ａは、縦長矩形としても円形としてもよいし、対向状に しても千鳥状にしてもよい。この阻流板１の短手方向（水路３内において水平方 向）に通水孔１ａを並設したのは、水量が減少し水位が低くなったような場合で も十分対応できるようにしたものである。また、阻流板１の下端部を切り欠くよ うに通水孔１ａを設けたのは、排水後の清掃作業を容易にするためである。この 例では、通水孔１ａを阻流板１のほぼ全面に設けたが、例えば該板１の上下方向 縁あるいは短手方向縁に沿うように、該孔１ａの配置を偏心させたり、形状又は 大きさの異なる通水孔１ａを所望配列により設けても差支えない。 この阻流板１の左右両側縁部及び下端縁部は、図５のように水路３の内側面３ ａ及び底面３ｂに固定される支持枠４に、摺動可能に挿入され、流れ方向に直交 するように支持されるものである。また、図示の支持枠４にかえ、水路３に溝条 （図示外）を設け、これを支持枠として阻流板１を支持してもよい。 この阻流板１に設けられる通水孔１ａの形状、個数及び配置を流れ方向に沿っ て変化させることにより、図５に示すように阻流板１を略等間隔に並設するよう な場合であっても、流速を所望に合わせて調整できる。勿論図５のように、次に 述べる調整板２を用いず、阻流板１のみによってもこの調節は可能である。 図２ないし図４に示すものは、上下迂流式の調整板２であって、これらにも板 厚方向に通水孔２ａが複数穿設される。図２の内、（ａ）で示すものは、水流が 水路３の底面３ｂ付近をくぐって流れるようにする調整板２であって、（ｂ）で 示すものは自由表面付近を流すものであり、これらは図６に示すように、それぞ れ矢印で示す流れ方向に沿って交互に、水路３に固定される支持枠４に挿入支持 され、阻流板１に対し摺動可能に重合されるものである。この通水孔２ａも、図 ２に示すように矩形のものを対向状に配してもよいし、千鳥状（図３）や円形（ 図４）としても差支えない。勿論、調整板２の通水孔２ａの形状及び配列は、阻 流板１の通水孔１ａのそれと符合するようにすることが望ましい。 Embodiments of the present invention will be described with reference to the drawings. Arrows in the figure indicate the flow direction. 1 to 4 show examples of the up-and-down detour type according to the present invention. A plurality of water passage holes 1a are formed in the baffle plate 1 shown in FIG. The flow rate, that is, the stirring intensity, is adjusted by the water level difference that occurs when water passes through the hole 1a. It is. This water passage hole 1a may be a vertically elongated rectangle or a circle, or may be formed in an opposing manner. It may also be staggered. The widthwise direction of this baffle plate 1 (horizontal direction within the waterway 3) The reason why water holes 1a are installed in parallel on the opposite side is when the water volume decreases and the water level becomes low. It has also been designed to be fully compatible with this. Also, cut out the lower end of the baffle plate 1. The reason why the water passage hole 1a was provided in the sea urchin is to facilitate cleaning work after draining water. this In the example, the water passage hole 1a is provided almost on the entire surface of the baffle plate 1, but for example, in the vertical direction of the plate 1. The hole 1a may be arranged eccentrically along the edge or the transverse edge, or the shape or Water passage holes 1a of different sizes may be provided in a desired arrangement. The left and right side edges and the lower edge of this baffle plate 1 are connected to the inner surface 3 of the water channel 3 as shown in FIG. a and the support frame 4 fixed to the bottom surface 3b, and is slidably inserted and perpendicular to the flow direction. It is supported to do so. Also, instead of the support frame 4 shown in the figure, a groove can be installed in the water channel 3. (not shown) may be provided and the baffle plate 1 may be supported using this as a support frame. The shape, number and arrangement of the water holes 1a provided in this baffle plate 1 are adjusted along the flow direction. By changing the flow rate, the baffle plates 1 can be arranged at approximately equal intervals as shown in FIG. Even in these cases, the flow rate can be adjusted as desired. Of course, as shown in Figure 5, then This adjustment is also possible using only the baffle plate 1 without using the adjustment plate 2 described above. What is shown in FIGS. 2 to 4 is an upper and lower detour type adjustment plate 2, and these also have plates. A plurality of water holes 2a are formed in the thickness direction. In Figure 2, (a) shows that the water flow is An adjustment plate 2 that allows the flow to pass through the vicinity of the bottom surface 3b of the water channel 3, and is The one shown flows near the free surface, and these flow as shown in Figure 6. Insert and support the support frame 4 fixed to the water channel 3 alternately along the flow direction shown by the arrow. and is superimposed on the baffle plate 1 so as to be slidable thereon. This water passage hole 2a is also As shown in Fig. 2, rectangular pieces may be arranged facing each other, or they may be arranged in a staggered pattern (Fig. 3) or circular (Fig. 3). Figure 4) may also be used. Of course, the shape and arrangement of the water holes 2a of the adjusting plate 2 It is desirable to match that of the water passage hole 1a of the flow plate 1.
【０００８】 図７のＡ−Ａ線断面図である図８において、左側が流入側であり、右側が流出 側である。まず、水路３に操作杆５を支持し、図６と同様に、支持枠４に阻流板 １及び調整板２を摺動可能に支持し、調整板２の上縁を操作杆５の符号位置に接 続具６をもって接続する。 そして、図８仮想線で示すように、操作杆５を傾斜させると、図９に拡大して 示すように、重合された阻流板１及び調整板２全体としての開度（通水孔１ａ、 ２ａの双方が開いている面積）を流れ方向に沿って漸増又は漸減させるなど変化 させることができる。 したがって、阻流板１及び調整板２を通過する際の水位差を変化させることが でき、フロックの成長に連れて段階的に攪拌強度を下げてゆく、いわゆるテーパ ート゛・フロッキュレーション方式とすることが容易にできる。 しかも、この攪拌強度の変化を、従来技術のように阻流板１、１間の間隔を増 加させてゆくことなく実現でき、水路３設備全体の規模をコンパクトにすること ができる。 加えて、この操作杆５の傾斜作業は、操作杆５に油圧シリンダーなど周知の昇 降手段（図示外）を用いれば、流水に触れることなく行なうことができ、容易か つ安全である。また、操作杆５を遠隔操作できるようにすることもできる。 上述の阻流板１及び調整板２は、図６と同様に支持枠４によって、縁部を支持 されており、従来技術のように鉄筋コンクリートなどにより重量大かつ高剛性に 形成しなくとも足り、樹脂板やステンレス板などの比較的薄くかつ軽量のものと することができ、取扱を容易にすることができる。[0008] In FIG. 8, which is a cross-sectional view taken along line A-A in FIG. 7, the left side is the inflow side, and the right side is the outflow side. It's on the side. First, the operating rod 5 is supported on the water channel 3, and a baffle plate is placed on the support frame 4 as shown in FIG. 1 and adjustment plate 2 are slidably supported, and the upper edge of adjustment plate 2 is brought into contact with the symbol position of operating rod 5. Connect using fitting 6. When the operating rod 5 is tilted as shown by the imaginary line in FIG. 8, it is enlarged as shown in FIG. As shown, the opening degree of the polymerized baffle plate 1 and adjustment plate 2 as a whole (water passage holes 1a, Changes such as gradually increasing or decreasing the area where both sides of 2a are open along the flow direction. can be done. Therefore, it is possible to change the water level difference when passing through the baffle plate 1 and the adjustment plate 2. The agitation intensity is gradually lowered as the flocs grow, so-called taper. It can easily be made into a flocculation method. Moreover, this change in agitation intensity can be controlled by increasing the distance between the baffle plates 1 and 1 as in the conventional technology. This can be achieved without adding additional waterways, and the overall scale of the three waterway facilities can be made compact. I can do it. In addition, this operation of tilting the operating rod 5 requires a well-known lifting device such as a hydraulic cylinder on the operating rod 5. If you use a means of descent (not shown), you can do it without coming into contact with running water. It is safe. Further, the control rod 5 can also be remotely controlled. The edges of the baffle plate 1 and adjustment plate 2 described above are supported by the support frame 4 as in FIG. Unlike conventional technology, it is made of reinforced concrete and has a large weight and high rigidity. It is not necessary to form the mold, and it is possible to use a relatively thin and lightweight material such as a resin plate or stainless steel plate. can be used to facilitate handling.
【０００９】 また、上記のように、阻流板１と調整板２とを直線状に相対移動させずとも、 図１０ないし図１４に示すように、同軸状に移動させることによっても、攪拌強 度の変化を実現することができる。 図１０は阻流板１を示し、この中央には円孔１６が、また同心円状に通水孔１ ａが、それぞれ設けられる。また図１１に示すものが、調整板２であって、これ にも円孔２６及び通水孔２ａが設けられる。そして、図１３に示すように、阻流 板１が水路３内側面３ａ及び底面３ｂに支持され、阻流板１に、円孔１６、２６ が符合するように、調整板２を重合し、軸支部１０により調整板２を阻流板１に 重合した状態において回動可能に支持する。 調整板２の周縁部には、歯２ｂが設けられ、この歯２ｂは歯車６に歯合するも のである。この歯車６は、操作杆５に軸着され、操作杆５の両端部は軸受７によ り水路３上方において回動可能に支持される。また、操作杆５の一端にはハンド ル８が取付けられ、このハンドル８を回動させることにより、阻流板１に対し調 整板２が回動し、阻流板１と調整板２全体としての開度を調節するものである。 この歯車６は、図１２及び図１４に示すように、流れ方向に沿って直径を異なら しめるものであり、該方向に沿って開度を変化させ、攪拌強度を調節するもので ある。 勿論、前記ハンドル８にかえて、図示していないが減速機などの伝動機構とモ ータによって、操作杆５を駆動してもよい。このようにすれば、遠隔操作も可能 である。[0009] Moreover, as mentioned above, even if the baffle plate 1 and the adjustment plate 2 are not moved relative to each other in a straight line, As shown in Figures 10 to 14, the stirring intensity can also be increased by moving coaxially. It is possible to realize a change in degree. FIG. 10 shows a baffle plate 1, with a circular hole 16 in the center and water holes 1 arranged concentrically. a are provided respectively. Also, what is shown in FIG. 11 is the adjustment plate 2, which Also, a circular hole 26 and a water passage hole 2a are provided. Then, as shown in Figure 13, The plate 1 is supported by the inner surface 3a and bottom surface 3b of the water channel 3, and the baffle plate 1 has circular holes 16, 26. overlap the adjustment plates 2 so that the Rotatably supported in the polymerized state. Teeth 2b are provided on the peripheral edge of the adjustment plate 2, and the teeth 2b mesh with the gear 6. It is. This gear 6 is pivoted to an operating rod 5, and both ends of the operating rod 5 are supported by bearings 7. It is rotatably supported above the waterway 3. In addition, a hand is attached to one end of the operating rod 5. A handle 8 is attached, and by rotating this handle 8, adjustment is made to the baffle plate 1. The adjustment plate 2 rotates to adjust the opening degree of the baffle plate 1 and adjustment plate 2 as a whole. As shown in FIGS. 12 and 14, this gear 6 has different diameters along the flow direction. The agitation intensity is adjusted by changing the opening degree along the direction. be. Of course, instead of the handle 8, a transmission mechanism such as a reduction gear and a motor may be used (not shown). The operating rod 5 may be driven by a motor. In this way, remote control is also possible. It is.
【００１０】 図１５、図１６及び図１７ないし図１９に示すものは、水平迂流式による場合 である。 図１５は、阻流板１のみによる例であり、図１６は阻流板１に調整板２を摺動 可能に重合した例である。 図１７に示す調整板２は、該図右側を流すものであり、右側縁部に縦長の通水 孔２ａが設けられている。 図１８に示す調整板２は、該図左側を流すものであり、左側縁部に正方形の通 水孔２ａが設けられている。 図１９に示す調整板２は、該図中央から右側を主に流し、左側部を若干流すも のである。これら調整板２の下端部を切り欠くように通水孔２ａを設けたのは、 排水後の清掃作業を容易にするためである。 これらの調整板２は、阻流板１と摺動可能に重合されるものである。そして、 阻流板１に対して、水平方向左右にずらすことにより、調整板２及び阻流板１全 体としての開度を調節するものである。 このように、開度を調節することにより、流速即ち攪拌強度をコントロールで きるので、特に水平迂流式を採用した従来技術のように、阻流壁間の間隔を流れ 方向に沿って増加し広大な面積を占めなくとも、図１５、図１６に示すように該 間隔を等間隔としてもよいので、設備の規模を小さくできる。0010 The cases shown in Figures 15, 16, and 17 to 19 are based on the horizontal detour type. It is. FIG. 15 shows an example using only the baffle plate 1, and FIG. 16 shows an example in which the adjustment plate 2 is slid on the baffle plate 1. This is an example of possible polymerization. The adjustment plate 2 shown in Fig. 17 is for flowing water on the right side of the figure, and has a vertically long water passage on the right edge. A hole 2a is provided. The adjusting plate 2 shown in Fig. 18 flows on the left side of the figure, and has a square passage on the left side edge. A water hole 2a is provided. The adjusting plate 2 shown in Fig. 19 mainly flows on the right side from the center of the figure, and slightly flows on the left side. It is. The reason why water holes 2a are provided by cutting out the lower end of these adjustment plates 2 is as follows. This is to facilitate cleaning work after draining water. These adjustment plates 2 are slidably superposed on the baffle plate 1. and, By shifting horizontally left and right with respect to the current baffle plate 1, the adjustment plate 2 and the current baffle plate 1 can be completely removed. This is to adjust the degree of opening of the body. In this way, by adjusting the opening degree, you can control the flow rate, that is, the stirring intensity. In particular, unlike the conventional technology that uses the horizontal detour type, the flow is Even if it increases along the direction and does not occupy a vast area, the Since the intervals may be equal, the scale of the equipment can be reduced.
【００１１】 勿論、本考案は上述の実施例に限定されるものではなく、その要旨を変更しな い範囲において種々変形することができる。[0011] Of course, the present invention is not limited to the above-mentioned embodiments, and the gist thereof may not be changed. Various modifications can be made within a wide range.

本考案は、上述のように構成したので、以下のような効果がある。 （１）流速、水量などに応じて、各阻流板の通水孔の開度を調節することによ り、柔軟かつ容易に攪拌強度を可変できる。 （２）多くの通水孔を水が通過することを利用したので、均一に水が攪拌され る利点がある。勿論、しばしば機械的エネルギを与える方式において見られるよ うな水路中の水の共回りを起こさず、短絡流や停滞を生じにくい。 （３）上下迂流式による場合、各阻流板は水路内面に設けた支持枠によって支 持されているので、阻流板自身の剛性を極めて大にする必要がなく、軽量で取扱 が容易なものとすることができる。また、阻流板は水路から離脱でき、水路内の 水や堆積物を容易に排除することができる。 （４）特に水平迂流式による場合、相隣る阻流板同志の間隔を水流方向に狭く することが可能であり又水深を大とすることにより、設備全体の占める面積を小 さくすることができる。 Since the present invention is configured as described above, it has the following effects. (1) By adjusting the opening degree of the water passage holes of each baffle plate according to the flow rate, water volume, etc. This makes it possible to vary the stirring intensity flexibly and easily. (2) Since water passes through many water holes, the water is evenly stirred. It has the advantage of Of course, as often seen in mechanical energy delivery systems, The water in the waterway does not rotate around, making it difficult to cause short-circuit flow or stagnation. (3) In the case of the vertical detour type, each baffle plate is supported by a support frame installed on the inner surface of the waterway. Since the baffle plate itself does not need to be extremely rigid, it is lightweight and easy to handle. can be made easy. In addition, the baffle plate can be removed from the waterway and Water and sediment can be easily removed. (4) Especially when using the horizontal detour type, the distance between adjacent baffle plates should be narrowed in the water flow direction. By increasing the water depth, the area occupied by the entire equipment can be reduced. can be reduced.
