発明の属する技術Technology to which the invention belongs

　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℃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, air may be blown into the lower portion of the inclined plate to clean 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 broaden the range of wastewater applied to the inclined plate settling device, it is also required to change the inclined plate installation angle to 90 ° C. 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.

発明が解決しようとする課題Problems to be solved by the invention

　傾斜板▲９▼の設置角度を簡単な構造で９０℃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 ° C. 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.

課題を解決するための手段Means for solving the problem

　本発明は、図−１に示す如く、前後２枚の傾斜板▲９▼の支持支点（穴▲１６▼、穴▲１７▼）を平行四辺形とし、傾斜板▲９▼を支持する、固定棒▲５▼、回転棒▲６▼、回転棒▲７▼、移動棒▲８▼、の部材を、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▼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 supporting fulcrum (hole (16), hole (17)) of the two front and rear inclined plates (9) is a parallelogram, and the fixed plate that supports the inclined plate (9) is fixed. The members of rod ▲ 5 ▼, rotating rod ▲ 6, rotating rod ▲ 7, moving rod ▲ 8 ▼ are fixed fulcrum ▲ 1 ▼, fixed fulcrum ▲ 2 ▼, moving fulcrum ▲ 3 ▼, moving fulcrum ▲ 4 ▼ By making the fulcrum to be joined with a parallelogram, the installation angle of the inclined plate 9 can be easily changed. In addition, the inclined plate <9> is suspended from the fixed rod <5>, and a moving rod <8> is installed to support the lower portion of the inclined plate <9>, thereby generating a tensile force on the inclined plate <9>. This compensated for the insufficient mechanical strength of the inclined plate (9) and solved the bending of the inclined plate (9) due to the precipitate.
In the present invention, when the inclined plate installation angle is 90 degrees, the inclined plate (9) becomes vertical. Therefore, the precipitate on the surface of the inclined plate {circle around (9)} easily slides down from the surface of the inclined plate {circle around (9)} by gravity.
Further, in the present invention, since the inclined plate installation angle can be set to 90 degrees or more, the precipitate on the inclined plate {circle around (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), the bubbles directly hit the precipitate adhering to the surface of the inclined plate (9), and even a sticky precipitate can be peeled off 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は傾斜板▲９▼を支持する構造の説明図を示す
　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▼が有る。移動棒▲８▼には傾斜板の設置枚数と同じ数の穴▲１７▼が有る。又、傾斜板▲９▼にはスリット▲１８▼がある。
　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り、固定支点▲１▼、固定支点▲２▼、は固定棒▲５▼により固定される。この固定棒▲５▼は沈殿池に固定され、傾斜板を吊り下げる。
　この平行四辺形において、固定棒▲５▼を固定辺として変形する構造となっており、移動棒▲８▼の移動量により傾斜板▲９▼の設置角度を変更する。
　回転棒▲６▼は、固定支点▲２▼を中心として回転する。回転棒▲７▼は、固定支点▲１▼を中心として回転する。
　移動棒▲８▼は、回転棒▲６▼の移動支点▲３▼と回転棒▲７▼の移動支点▲４▼により支持され、回転棒▲６▼、回転棒▲７▼の動きに連動する。
　傾斜板▲９▼の上部には上部ピン▲１０▼が固定し取り付け取り付けられ、傾斜板▲９▼の下部には下部ピン▲１１▼が固定し取り付けられている。
　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。尚、上部ピン▲１０▼と下部ピン▲１１▼を傾斜板▲９▼に取り付ける方法は、溶接でも、圧着でも一体化したものでも良い。　この事により、傾斜板▲９▼の横方向の強度が増加する。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▼が開いている。傾斜板▲９▼は両サイドの上部ピン▲１０▼を穴▲１６▼に挿入し固定棒▲５▼に吊り下げる。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▼が開いている。傾斜板▲９▼は両サイドの下部ピン▲１１▼を穴▲１７▼に挿入し下部を支持し、移動棒▲８▼を移動させ傾斜板▲９▼の設置角度を変更する。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。
　上部ピン▲１０▼は穴▲１６▼の中で自由に回転できる。又、下部ピン▲１１▼も穴▲１７▼の中で自由に回転できる。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▼、穴▲１７▼）は平行四辺形となる。この事により、移動棒▲８▼、が前後に移動すると傾斜板▲９▼の設置角度は変更される。
　移動棒▲８▼は回転棒▲６▼、回転棒▲７▼が固定支点▲２▼、固定支点▲１▼を支点とし回転する事により移動される。この時、移動棒▲８▼、回転棒▲６▼、回転棒▲７▼は傾斜板▲９▼の両サイドに設置され、同一に動く構造とする。
　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。
　通常時、傾斜板▲９▼は図−１に於いて移動支点▲３▼に位置で使用される。
　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▼の設置角度が大きくなり、傾斜板▲９▼表面より沈殿物が除去される。
　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▲１▼を支点として回転し、移動支点▲３▼、移動支点▲４▼、は３’、４’の位置より通常の位置に移動し傾斜板▲９▼の沈降装置としての効果を発揮し廃水中の沈殿物が除去される。
　尚、前段吊上ロープ▲１２▼と後段吊上ロープ▲１３▼は、一体でも、分離でも良い。又、傾斜板▲９▼の両サイド回転棒▲６▼、回転棒▲７▼に対し夫々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。
　上記の構造物を傾斜板▲９▼の両サイドに設置し動きを連動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。尚、前段吊上ロープ▲１２▼と後段吊上ロープ▲１３▼は一本で両サイドの移動棒▲８▼を移動させる事も出来る。
　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▼、穴▲１７▼があるが、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。
　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、前後２枚の傾斜板▲２１▼の支持支点（穴▲２２▼、穴▲２３▼）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。しかし、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 in which the inclined plate {circle over (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 shows an explanatory diagram of the structure for supporting the inclined plate (9). The inclined plate settling device of the present invention is a variable installation angle of the inclined plate (9) installed in the settling basin of the wastewater treatment device. Fixed fulcrum (1), fixed fulcrum (2), moving fulcrum (3), moving fulcrum (4), fixed bar (5), rotating bar (6), rotating bar (7), moving bar (8) , Inclined plate (9), upper pin (10), lower pin (11), front hoisting rope (12), rear hoisting rope (13), rope drive device (14), rope guide (15) Is done. The fixed bar (5) has the same number of holes (16) as the number of inclined plates installed. The moving rod (8) has the same number of holes (17) as the number of inclined plates installed. The inclined plate (9) has a slit (18).
Connecting fixed fulcrum (1), fixed fulcrum (2), moving fulcrum (3), and moving fulcrum (4) results in a parallelogram. Fixed fulcrum (1) and fixed fulcrum (2) are fixed bars (5). It is fixed by. This fixed rod (5) is fixed to the sedimentation basin and suspends the inclined plate.
This parallelogram has a structure in which the fixed bar (5) is deformed as a fixed side, and the installation angle of the inclined plate (9) is changed according to the amount of movement of the moving bar (8).
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 the moving fulcrum (3) of the rotating rod (6) and the moving fulcrum (4) of the rotating rod (7) and interlocks with the movement of the rotating rod (6) and the rotating rod (7). .
An upper pin (10) is fixed and attached to the upper part of the inclined plate (9), and a lower pin (11) is fixed and attached to the lower part of the inclined plate (9).
The upper pin (10) and the lower pin (11) are installed by rounding a part of the inclined plate (9). The upper pin (10) and the lower pin (11) may be attached to the inclined plate (9) by welding, crimping or an integrated method. As a result, the lateral strength of the inclined plate (9) increases. Moreover, the strength in the vertical direction is increased by inserting a plurality of slits (18) in the vertical direction of the inclined plate (9).
The fixing bar (5) has a hole (16) into which the upper pin (10) of the inclined plate (9) can be inserted. The inclined plate (9) inserts the upper pins (10) on both sides into the holes (16) and suspends them on the fixing rod (5). Further, the moving rod (8) has a hole (17) through which the lower pin (11) of the inclined plate (9) can be inserted. The inclined plate (9) inserts the lower pins (11) on both sides into the holes (17) to support the lower portion, and moves the moving rod (8) to change the installation angle of the inclined plate (9). The manufacturing error of the inclined plate (9) can be absorbed by making the hole (17) into a horseshoe shape.
The upper pin (10) can freely rotate in the hole (16). The lower pin (11) can also freely rotate in the hole (17). 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 {circle around (16)}, hole {circle around (17)}) of the two front and rear inclined plates {circle over (9)} is a parallelogram. As a result, when the moving rod {8} moves back and forth, the installation angle of the inclined plate {9} is changed.
The moving rod (8) is moved by rotating the rotating rod (6) and the rotating rod (7) with the fixed fulcrum (2) and the fixed fulcrum (1) as fulcrums. At this time, the moving rod (8), the rotating rod (6), and the rotating rod (7) are installed on both sides of the inclined plate (9) so as to move in the same manner.
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).
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 device (14), the rotating rod (6) and the rotating rod (7) are fixed fulcrum (2) and fixed. Rotating around fulcrum (1) as a fulcrum, moving fulcrum (3) and moving fulcrum (4) move to 3 ', 4', and the installation angle of inclined plate (9) increases, from the surface of inclined plate (9) The precipitate is removed.
When pulling the former stage lifting rope (12) with the rope drive device (14), the rotating rod (6) and the rotating rod (7) rotate around the fixed fulcrum (2) and the fixed fulcrum (1) as the fulcrum. The fulcrum (3) and the moving fulcrum (4) move from the positions 3 ′ and 4 ′ to the normal position, and the effect of the inclined plate (9) as a settling device is exerted to remove the sediment in the wastewater.
Incidentally, the front-stage hoisting rope (12) and the rear-stage hoisting rope (13) may be integrated or separated. In addition, there are one or two cases for the rotating rods (6) and (7) on both sides of the inclined plate (9). Further, the front hoisting rope (12) and the rear hoisting rope (13) are guided by a rope guide (15).
The installation angle of the inclined plate (9) can be changed by installing the above structure on both sides of the inclined plate (9) and interlocking the movements. In addition, the front stage lifting rope (12) and the rear stage lifting rope (13) can move the moving bars (8) on both sides by one.
When changing the installation angle of the inclined plate (9), a chain can be used instead of a rope. Further, it is also possible to rotate by directly applying the rotational force to the fixed fulcrum (1) and fixed fulcrum (2) of the rotary rod (6) and the rotary rod (7).
Further, in order to maintain the installation angle of the inclined plate (9), stoppers are installed on the rotating rod (6), the rotating rod (7), and the moving rod (8) to prevent the rope from being constantly tensioned.
The fixed rod (5) and the movable rod (8) have holes (16) and (17), but instead of the holes, the upper pin (10) and the lower pin (11) of the inclined plate (9) are supported. A fixed seat can be installed.
Next, an embodiment in which the inclined plate {circle over (9)} of the present invention is installed in two stages will be described. FIG.
If the sedimentation basin is deep, there is a limit to the length of the inclined plate {9}, so multiple inclined plates {9} are installed. In this case, the hole {22} of the upper pin {circle around (10)} that suspends the inclined plate {circle around (21)} installed on the lower portion is installed on the moving rod {8} of the upper inclined plate {circle around (9)}.
The method of changing the installation angle of the inclined plate {circle around (21)} installed at the lower part is performed by the moving rod {8} of the inclined plate {circle around (9)} installed at the upper part. The support of the inclined plate (21) is the same as the upper inclined plate (9), and the supporting fulcrum (hole (22), hole (23)) of the two front and rear inclined plates (21) is a parallelogram. Install to be.
The moving rod (24) of the lower inclined plate (21) is moved in the vertical direction by rotating the lower rotating rod (25) with the fulcrum (20) as a fulcrum. At this time, the fulcrum {circle around (20)} is structured so as to slide freely in the vertical direction. However, it is 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.

発明の効果The invention's effect

　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。In general, the inclined plate (9) is installed at an angle of 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.
Further, in the present invention, since the installation angle of the inclined plate {circle over (9)} can be changed to 90 ° or more, it becomes possible to remove sediments that are viscous due to gravity or bubbles from the surface of the inclined plate {circle around (9)}. It is possible to prevent blockage between 9 ▼. Therefore, it is possible to use the inclined plate settling device even with wastewater whose sediment is viscous.
