Description
本発明は、廃水処理における固液分離を行う為の、傾斜板沈降装置に関するものである。 The present invention relates to an inclined plate settling device for performing solid-liquid separation in wastewater treatment.
傾斜板沈降装置は固液分離の沈殿池に設置して、沈殿の有効面積を増加し、廃水処理における固液分離特性を向上させるものである。
傾斜板の有効面積は下記の式で示される。
傾斜板有効面積＝傾斜板実面積×ＣＯＳ（傾斜板設置角度）
上式より、傾斜板設置角度は小さいほど有効面積が大きくなる。従って傾斜板設置角度は傾斜板沈降装置の性能に大きく影響する。
尚、傾斜板の表面に沈殿した沈殿物は、重力により傾斜板表面を滑り落ち、自然落下する。その為、傾斜板設置角度の低下には限界がある。通常、沈殿物が傾斜板より滑り落ちる限界を考慮し、傾斜板設置角度は６０度にて使用される場合が多い。
又、沈殿物に粘性があると重力だけでは、沈殿物が傾斜板表面を滑り落ちず、傾斜板の間に沈殿物が堆積し閉塞する。傾斜板の閉塞を防止する為、傾斜板の下部に空気を吹き込んで傾斜板を洗浄する場合もある。しかし、空気を吹き込んでも気泡が当たるのは傾斜板の裏面であり傾斜板の表面を洗浄する事は出来ない。
傾斜板沈降装置の適用廃水の範囲を広げる為、又、維持管理面からも傾斜板設置角度を９０度以上に変更することが求められる。
しかし、従来、傾斜板設置角度を変更する場合、傾斜板に曲げ力、圧縮力を発生させた。その為、傾斜板の構造は強靭性が必要となり、具現化が困難であり、傾斜板は設置角度を固定化して使用していた。
又、沈殿物に粘性がある廃水には、沈殿物により傾斜板が閉塞するので傾斜板沈降装置は使用できなかった。The inclined plate settling device is installed in a sedimentation basin for solid-liquid separation to increase the effective area of sedimentation and improve the solid-liquid separation characteristics in wastewater treatment.
The effective area of the inclined plate is expressed by the following formula.
Effective area of inclined plate = Actual area of inclined plate x COS (Inclined plate installation angle)
From the above equation, the effective area increases as the inclined plate installation angle decreases. Therefore, the inclined plate installation angle greatly affects the performance of the inclined plate settling device.
In addition, the sediment deposited on the surface of the inclined plate slides down the surface of the inclined plate due to gravity and falls naturally. Therefore, there is a limit to the decrease in the inclined plate installation angle. Usually, in consideration of the limit that the sediment slides down from the inclined plate, the inclined plate installation angle is often used at 60 degrees.
Further, if the precipitate is viscous, the gravity does not slide down the inclined plate surface only by gravity, and the deposit accumulates and closes between the inclined plates. In order to prevent the inclined plate from being blocked, the inclined plate may be washed by blowing air into the lower portion of the inclined plate. However, even if air is blown in, air bubbles hit the back surface of the inclined plate, and the surface of the inclined plate cannot be cleaned.
In order to widen the range of wastewater applied to the inclined plate settling device, it is also required to change the inclined plate installation angle to 90 degrees or more from the maintenance and management aspect.
However, conventionally, when the inclined plate installation angle is changed, bending force and compressive force are generated on the inclined plate. Therefore, the structure of the inclined plate requires toughness and is difficult to realize, and the inclined plate has been used with a fixed installation angle.
In addition, the inclined plate settling device cannot be used for waste water having a viscous precipitate because the inclined plate is blocked by the precipitate.
傾斜板（９）の設置角度を簡単な構造で９０度以上変更できれば、可変式傾斜板の具現化が可能となり、その結果、傾斜板（９）の清掃が容易となるので、沈殿物に粘性がある廃水にも傾斜板沈降装置の適用が可能となる。 If the installation angle of the inclined plate (9) can be changed by 90 degrees or more with a simple structure, a variable-type inclined plate can be realized. As a result, the inclined plate (9) can be easily cleaned, and the deposit is viscous. An inclined plate settling device can be applied to some wastewater.
本発明は、図１に示す如く、傾斜板（９）の支持支点を穴（１６−１）、穴（１６−２）、穴（１６−３）、・・・・、穴（１７−１）、穴（１７−２）、穴（１７−３）、・・・・とし、前後２枚の傾斜板（９）を支持する支持支点、｛穴（１６−１）、穴（１６−２）、穴（１７−１）、穴（１７−２）、｝の配置関係を平行四辺形とする。固定棒（５）、回転棒（６）、回転棒（７）、移動棒（８）、の部材により傾斜板（９）を支持する外枠を形成し、固定支点（１）、固定支点（２）、移動支点（３）、移動支点（４）、で接合する支点を平行四辺形とする事により、傾斜板（９）の設置角度の変更が簡単にできる構造にした。又、傾斜板（９）を固定棒（５）に設置した穴（１６）より吊り下げ、傾斜板（９）の下部を支持する為に移動棒（８）を設置し、傾斜板（９）に引張力を発生させる構造とする事により、傾斜板（９）の機械的強度不足を補い、沈殿物による傾斜板（９）の曲がりを解決した。
本発明では、傾斜板設置角度を９０度にすると、傾斜板（９）は垂直となる。その為、傾斜板（９）表面の沈殿物が傾斜板（９）表面より重力により容易に滑り落ちることになる。
更に本発明では傾斜板設置角度を９０度以上にすることができので傾斜板（９）表面の沈殿物は重力により剥離し傾斜板（９）より直接落下することになる。又、この時、傾斜板（９）の下部より空気を吹き込むと、気泡が傾斜板（９）表面に付着した沈殿物に直接当たり粘着性のある沈殿物でも傾斜板（９）表面より剥離できる。In the present invention, as shown in FIG. 1, the support fulcrum of the inclined plate (9) is provided with holes (16-1), (16-2), (16-3),. ), Hole (17-2), hole (17-3),... And supporting fulcrum for supporting the two front and rear inclined plates (9), {hole (16-1), hole (16-2) ), Hole (17-1), hole (17-2),} is a parallelogram. An outer frame that supports the inclined plate (9) is formed by the members of the fixed rod (5), the rotating rod (6), the rotating rod (7), and the moving rod (8), and the fixed fulcrum (1), 2) By making the fulcrum to be joined at the movement fulcrum (3) and the movement fulcrum (4) into a parallelogram, the installation angle of the inclined plate (9) can be easily changed. In addition, the inclined plate (9) is suspended from the hole (16) installed in the fixed rod (5), and the moving rod (8) is installed to support the lower portion of the inclined plate (9), and the inclined plate (9) By adopting a structure that generates a tensile force, the mechanical strength of the inclined plate (9) was compensated for and the bending of the inclined plate (9) due to the precipitate was solved.
In the present invention, when the inclined plate installation angle is 90 degrees, the inclined plate (9) is vertical. Therefore, the precipitate on the surface of the inclined plate (9) easily slides down from the surface of the inclined plate (9) due to gravity.
Furthermore, in the present invention, since the inclined plate installation angle can be 90 degrees or more, the precipitate on the surface of the inclined plate (9) is peeled off by gravity and directly falls from the inclined plate (9). At this time, if air is blown in from the lower part of the inclined plate (9), even if the air bubbles are directly applied to the precipitate adhering to the surface of the inclined plate (9), the adhesive deposit can be separated from the surface of the inclined plate (9). .
次に本発明の傾斜板（９）を１段設置した場合の実施形態について説明する
図１は傾斜板（９）を１段設置した場合の実施例側面図を示す。
図２は図１のＡ−Ａ断面を示している。図３は１枚の傾斜板（９）を設置する構造の説明図を示す。図５は複数枚の傾斜板（９）を組み立てた状態を示す。
本発明の傾斜板沈降装置は、廃水処理装置の沈殿池に設置した傾斜板（９）の設置角度を可変式にしたものであり、固定支点（１）、固定支点（２）、移動支点（３）、移動支点（４）、固定棒（５）、回転棒（６）、回転棒（７）、移動棒（８）、傾斜板（９）、上部ピン（１０）、下部ピン（１１）、前段吊上ロープ（１２）、後段吊上ロープ（１３）、ロープ駆動装置（１４）、ロープガイド（１５）、により構成される。固定棒（５）には傾斜板の設置枚数と同じ数の穴（１６−１）、穴（１６−２）、穴（１６−３）、・・・・が有る。移動棒（８）には傾斜板の設置枚数と同じ数の穴（１７−１）、穴（１７−２）、穴（１７−３）、・・・・が有る。又、傾斜板（９）にはスリット（１８）がある。
穴（１６）は、穴（１６−１）、穴（１６−２）・・・で有り、固定棒（５）に設置した穴の総称を示したものである。穴（１６−１）とは一枚目の傾斜板（９）に該当する穴を意味する。以後二枚目の傾斜板（９）に該当する穴を（１６−２）、三枚目の傾斜板に該当する穴を（１６−３）と記載する。
穴（１７）は、穴（１７−１）、穴（１７−２）・・・で有り、移動棒（８）に設置した穴の総称を示したものである。穴（１７−１）とは一枚目の傾斜板（９）に該当する穴を意味する。以後二枚目の傾斜板（９）に該当する穴を（１７−２）、三枚目の傾斜板に該当する穴を（１７−３）と記載する。
固定棒（５）は傾斜板沈降装置を設置する沈殿池に固定され、図５の如く傾斜板（９）を吊り下げる。
固定支点（１）、固定支点（２）、は固定棒（５）に設置される。回転棒（６）は固定支点（２）を中心に回転する。回転棒（７）は固定支点（１）、を中心に回転する。移動棒（８）は回転棒（６）に有る移動支点（３）と、回転棒（７）に有る移動支点（４）で支持されている。尚、移動支点（３）と移動支点（４）と移動棒（８）は回転できる支点で支持されている。
固定支点（１）、固定支点（２）、移動支点（３）、移動支点（４）、を結ぶと平行四辺形となる。この平行四辺形は、固定棒（５）を固定辺として変形する構造となっている。傾斜板（９）の上部には上部ピン（１０）が有り、下部には下部ピン（１１）が有る。
この上部ピン（１０）と下部ピン（１１）は傾斜板（９）の一部を丸めて設置する。又、傾斜板（９）の縦方向にスリット（１８）を複数入れることにより縦方向の強度が増加する。
固定棒（５）には、傾斜板（９）の上部ピン（１０）を挿入できる穴（１６）が有る。傾斜板（９）は上部ピン（１０）を穴（１６）に挿入する事により固定棒（５）より吊り下げる事が出来る。又、移動棒（８）には、傾斜板（９）の下部ピン（１１）を挿入できる穴（１７）が有る。傾斜板（９）は下部ピン（１１）を穴（１７）に挿入し下部を支持している。穴（１７）は馬蹄形にする事により傾斜板（９）の製作誤差が吸収できる。
傾斜板（９）の下部ピン（１１）は移動棒（８）の重量により下方に引っ張られるので、傾斜板（９）には引張力が働き、縦方向に曲がりにくくなる。
前後２枚の傾斜板（９）の支持支点｛穴（１６−１）、穴（１６−２）、穴（１７−１）、穴（１７−２）｝は平行四辺形となる。
図５に示す如く外枠は傾斜板（９）の両サイドに設置される。傾斜板（９）は両サイドの、固定棒（５）、と移動棒（８）により上下を支持される。移動棒（８）は回転棒（６）、回転棒（７）、によ固定棒（５）より吊り下げられている。
回転棒（６）は、前段吊上ロープ（１２）により引っ張られ回転する。回転棒（７）は、後段吊上ロープ（１３）に引っ張られ回転する。この事により移動棒（８）は水平方向に移動する。
移動棒（８）を水平方向に移動させると傾斜板（９）は、穴（１６）を中心に回転する。この時、穴（１６）は移動しない。ので移動棒（８）に設置された穴（１７）が水平方向へ移動する量だけ傾斜板（９）の設置角度が変更できる。
通常時、傾斜板（９）は図１に於いて移動支点（３）の位置で使用される。
傾斜板（９）を掃除する時、後段吊上ロープ（１３）をロープ駆動装置（１４）、にて引っ張ると、回転棒（６）、回転棒（７）、が固定支点（２）、固定支点（１）を支点として回転し、移動支点（３）、移動支点（４）、は（３）’、（４）’に移動し傾斜板（９）の設置角度が変更される。
前段吊上ロープ（１２）をロープ駆動装置（１４）にて引っ張ると、回転棒（６）、回転棒（７）、が固定支点（２）、固定支点（２）を支点として回転し、移動支点（３）’、移動支点（４）’、は（３）、（４）の位置に変更される。
尚、前段吊上ロープ（１２）と後段吊上ロープ（１３）は、一体でも、分離でも良く、又、傾斜板（９）の両サイトの外枠に対し１本、又は２本のケースがある。 又、前段吊上ロープ（１２）と後段吊上ロープ（１３）は、ロープガイド（１５）によりガイドされる。
ロープ駆動装置（１４）により傾斜板（９）の両サイドの外枠を同時に同量だけ変形させることにより傾斜板（９）の設置角度を変更することが出来る。
傾斜板（９）の設置角度を変更する場合、ロープの替わりにチェーンとすることもできる。又、直接回転力を回転棒（６）、回転棒（７）の固定支点（１）、固定支点（２）に加えて回転させる事も可能である。
又、傾斜板（９）の設置角度を保持する為、回転棒（６）、回転棒（７）、移動棒（８）にストッパーを設置し、常時ロープに張力が発生することを防止する。
固定棒（５）と移動棒（８）には穴（１６−１）、穴（１６−２）、穴（１６−３）、・・・・、穴（１７−１）、（１７−２）、（１７−３）・・・・、が有るが、穴の替わりに、傾斜板（９）の上部ピン（１０）と下部ピン（１１）を支持できる固定座を設置しても良い。
次に本発明の傾斜板（９）を２段設置した場合の実施形態について説明する
図４は傾斜板（９）を２段設置した場合の実施例側面図を示す。
沈殿池が深い場合は、傾斜板（９）の長さに限界があるので傾斜板（９）を複数段設置する。この場合は、上部傾斜板（９）の移動棒（８）に、下部に設置する傾斜板（２１）を吊り下げる上部ピン（１０）の穴（２２）を設置する。即ち下部に設置する傾斜板（２１）の固定棒の役割を上部傾斜板（９）の移動棒（８）が兼用する事になる。
下部に設置した傾斜板（２１）の設置角度を変更する方法は上部に設置した傾斜板（９）の移動棒（８）により行う。又、傾斜板（２１）の支持は上部の傾斜板（９）と同じであり、前記同様に前後２枚の傾斜板（２１）の支持支点｛穴（２２−１）、穴（２２−２）、穴（２３−１）、穴（２３−２）｝を平行四辺形となるように設置する。
下部の傾斜板（２１）の移動棒（２４）は下部の回転棒（２５）、が支点（２０）を支点とし回転する事により上下方向に移動される。この時、支点（２０）は上下方向を自由にスライドできる構造とする。この事により、水平方向の動きを抑制し下部に設置した傾斜板（２１）の設置角度の変更を可能にする。尚、支点（１９）は移動支点（３）と同じ場所でも図４の如く別々でも良い。Next, an embodiment when the inclined plate (9) of the present invention is installed in one stage will be described. FIG.
FIG. 2 shows an AA cross section of FIG. FIG. 3 is an explanatory view of a structure in which one inclined plate (9) is installed . FIG. 5 shows a state in which a plurality of inclined plates (9) are assembled.
The inclined plate sedimentation device of the present invention is a variable angle installation of the inclined plate (9) installed in the settling basin of the wastewater treatment device. The fixed fulcrum (1), fixed fulcrum (2), moving fulcrum ( 3), moving fulcrum (4), fixed rod (5), rotating rod (6), rotating rod (7), moving rod (8), inclined plate (9), upper pin (10), lower pin (11) , The front hoisting rope (12), the rear hoisting rope (13), the rope driving device (14), and the rope guide (15). The fixed rod (5) has the same number of holes (16-1), holes (16-2), holes (16-3),. The moving rod (8) has the same number of holes (17-1), holes (17-2), holes (17-3),. The inclined plate (9) has a slit (18).
A hole (16) is a hole (16-1), a hole (16-2)..., And is a generic name of holes installed in the fixing rod (5). The hole (16-1) means a hole corresponding to the first inclined plate (9). Hereinafter, the hole corresponding to the second inclined plate (9) is described as (16-2), and the hole corresponding to the third inclined plate is described as (16-3).
The hole (17) is a hole (17-1), a hole (17-2)..., And is a generic name of the holes installed on the movable rod (8). The hole (17-1) means a hole corresponding to the first inclined plate (9). Hereinafter, the hole corresponding to the second inclined plate (9) is referred to as (17-2), and the hole corresponding to the third inclined plate is referred to as (17-3).
The fixed rod (5) is fixed to a settling basin where an inclined plate settling device is installed, and suspends the inclined plate (9) as shown in FIG .
The fixed fulcrum (1) and the fixed fulcrum (2) are installed on the fixed rod (5) . The rotating rod (6) rotates around the fixed fulcrum (2). The rotating rod (7) rotates around the fixed fulcrum (1). The moving rod (8) is supported by a moving fulcrum (3) on the rotating rod (6) and a moving fulcrum (4) on the rotating rod (7). The movement fulcrum (3), the movement fulcrum (4), and the movement bar (8) are supported by a fulcrum that can rotate.
When the fixed fulcrum (1), the fixed fulcrum (2), the movement fulcrum (3), and the movement fulcrum (4) are connected, a parallelogram is formed. This parallelogram has a structure in which the fixed rod (5) is deformed as a fixed side. The upper part of the inclined plate (9) has an upper pin (10) and the lower part has a lower pin (11).
The upper pin (10) and the lower pin (11) are installed by rounding a part of the inclined plate (9). Moreover, the intensity | strength of a vertical direction increases by putting several slit (18) in the vertical direction of an inclined plate (9).
The fixing rod (5) has a hole (16) into which the upper pin (10) of the inclined plate (9) can be inserted. The inclined plate (9) can be suspended from the fixed rod (5) by inserting the upper pin (10) into the hole (16). Moreover, the moving rod (8) has a hole (17) into which the lower pin (11) of the inclined plate (9) can be inserted. The inclined plate (9) supports the lower part by inserting the lower pin (11) into the hole (17). By making the hole (17) horseshoe-shaped, manufacturing errors of the inclined plate (9) can be absorbed.
Since the lower pin (11) of the inclined plate (9) is pulled downward by the weight of the moving rod (8), a tensile force acts on the inclined plate (9) and it is difficult to bend in the vertical direction.
The supporting fulcrum {hole (16-1), hole (16-2), hole (17-1), hole (17-2)} of the two front and rear inclined plates (9) are parallelograms.
As shown in FIG. 5, the outer frame is installed on both sides of the inclined plate (9). The inclined plate (9) is supported up and down by a fixed rod (5) and a movable rod (8) on both sides. The moving rod (8) is suspended from the fixed rod (5) by the rotating rod (6) and the rotating rod (7).
The rotating rod (6) is pulled and rotated by the front hoisting rope (12). The rotating rod (7) is pulled and rotated by the rear hoisting rope (13). As a result, the moving rod (8) moves in the horizontal direction.
When the moving rod (8) is moved in the horizontal direction, the inclined plate (9) rotates around the hole (16) . At this time, the hole (16) does not move. Therefore, the installation angle of the inclined plate (9) can be changed by the amount by which the hole (17) installed in the moving rod (8) moves in the horizontal direction .
Normally, the inclined plate (9) is used at the position of the moving fulcrum (3) in FIG.
When cleaning the inclined plate (9), pulling the rear lifting rope (13) with the rope drive (14), the rotating rod (6) and rotating rod (7) are fixed fulcrum (2) and fixed. The fulcrum (1) is rotated as a fulcrum, the movement fulcrum (3) and the movement fulcrum (4) are moved to (3) ′, (4) ′, and the installation angle of the inclined plate (9) is changed.
When pulling the front hoisting rope (12) with the rope drive device (14), the rotating rod (6) and rotating rod (7) rotate around the fixed fulcrum (2) and fixed fulcrum (2) and move. The fulcrum (3) ′ and the movement fulcrum (4) ′ are changed to positions (3) and (4) .
It should be noted that the front hoisting rope (12) and the rear hoisting rope (13) may be integrated or separated, and one or two cases are provided for the outer frames of both sites of the inclined plate (9). is there. The front-stage hoisting rope (12) and the rear-stage hoisting rope (13) are guided by a rope guide (15).
The installation angle of the inclined plate (9) can be changed by simultaneously deforming the outer frames on both sides of the inclined plate (9) by the same amount by the rope drive device (14) .
When changing the installation angle of the inclined plate (9), a chain can be used instead of a rope. Moreover, it is also possible to rotate by applying a direct rotational force to the fixed fulcrum (1) and fixed fulcrum (2) of the rotating rod (6) and rotating rod (7).
Also, in order to maintain the installation angle of the inclined plate (9), stoppers are installed on the rotating rod (6), rotating rod (7), and moving rod (8) to prevent tension on the rope at all times.
Hole (16-1), hole (16-2), hole (16-3), ..., hole (17-1), (17-2) ), (17-3)..., But a fixed seat that can support the upper pin (10) and the lower pin (11) of the inclined plate (9) may be installed instead of the hole.
Next, an embodiment in which the inclined plate (9) of the present invention is installed in two stages will be described. FIG. 4 shows a side view of an example in which the inclined plate (9) is installed in two stages.
When the sedimentation basin is deep, there is a limit to the length of the inclined plate (9), so that the inclined plate (9) is installed in a plurality of stages. In this case, the hole (22) of the upper pin (10) for suspending the inclined plate (21) to be installed in the lower part is installed in the moving rod (8) of the upper inclined plate (9). That is, the moving rod (8) of the upper inclined plate (9) also serves as the fixed rod of the inclined plate (21) installed at the lower portion.
The method of changing the installation angle of the inclined plate (21) installed in the lower part is performed by the moving rod (8) of the inclined plate (9) installed in the upper part. Further, the support of the inclined plate (21) is the same as that of the upper inclined plate (9), and the supporting fulcrum {hole (22-1), hole (22-2) of the two inclined plates (21) in the same manner as described above. ), Hole (23-1), hole (23-2)} are installed in a parallelogram.
The moving rod (24) of the lower inclined plate (21) is moved in the vertical direction by rotating the lower rotating rod (25) about the fulcrum (20). At this time, the fulcrum (20) has a structure that can slide freely in the vertical direction. This makes it possible to change the installation angle of the inclined plate (21) installed in the lower part while suppressing horizontal movement. The fulcrum (19) may be the same location as the movement fulcrum (3) or may be separate as shown in FIG.
通常、傾斜板（９）の設置角度は沈殿物が傾斜板（９）より滑り落ちる限界より６０度で使用する場合が多い。しかし、清掃時に傾斜板（９）の設置角度を可変出来るのなら、通常時の傾斜板設置角度を６０度以下で使用できる。すなわち、傾斜板沈降装置の有効面積を増加できる。
又、本発明は、傾斜板（９）の設置角度を９０度以上に変更できるので、傾斜板（９）の表面より重力、又は気泡により粘性のある沈殿物の除去が可能となり、傾斜板（９）間の閉塞を防止しできる。従って、沈殿物に粘性がある廃水でも、傾斜板沈降装置の使用が可能となる。Usually, the installation angle of the inclined plate (9) is often used at 60 degrees from the limit where the sediment slides down from the inclined plate (9). However, if the installation angle of the inclined plate (9) can be varied during cleaning, the normal inclined plate installation angle can be used at 60 degrees or less. That is, the effective area of the inclined plate settling device can be increased.
In the present invention, since the installation angle of the inclined plate (9) can be changed to 90 degrees or more, it becomes possible to remove precipitates that are viscous due to gravity or bubbles from the surface of the inclined plate (9). 9) The blockage between can be prevented. Therefore, it is possible to use the inclined plate settling device even with wastewater whose sediment is viscous.
