Description
この発明は、上下水処理場において使用する円形沈殿池のトラフ等に付着する藻などを効果的に除去するための清掃装置に関する。 This invention relates to a cleaning device for effectively removing algae and other debris adhering to the troughs of circular sedimentation tanks used in water and wastewater treatment plants.
上下水処理場において使用する円形沈殿池においては、特に水が浄化された処理工程の後段における最終沈殿池においては、被処理水の溶存酸素が増え、この状態で光と適度の栄養分が作用することにより、沈殿池の処理水が越流するノッチおよびノッチを通じて流出するトラフに藻が多量に付着する形で発生し生長する。
この発生した藻により沈殿池の貯蔵水が汚染され、また大量に発生した藻が腐敗することで腐敗臭が発生する。
この発生した藻を除去するには、手作業によるブラシ掛けや高圧ジェットによる洗浄が行われるが作業者を必要とし、夏には藻の成長が早く作業者の増員が必要になる。また、防藻塗料を施して藻の付着を抑制する方法があるが、塗料を施す前に藻をデッキブラシなどで除去したのち殺藻し、さらに水洗と乾燥を行なってワイヤブラシなどによってケレンするといったように大変な作業が必要である。しかも効き目の持続性が１年半程度であるため塗り替えの必要がある。
In circular sedimentation tanks used in water and wastewater treatment plants, particularly in the final sedimentation tank at the end of the treatment process where the water has been purified, the dissolved oxygen in the treated water increases. In this state, light and adequate nutrients act on the treated water, causing a large amount of algae to grow and attach to the notch through which the treated water overflows and the trough through which it flows.
The algae that grow contaminate the water stored in the sedimentation tank, and the large amount of algae that decomposes generates a foul odor.
Removing this algae requires manual brushing or high-pressure jet cleaning, which necessitates workers, and in the summer, the algae grows quickly, requiring additional workers. Another method involves applying anti-algal paint to suppress algae growth, but this requires a lot of work, including removing the algae with a deck brush before painting, then killing the algae, followed by rinsing and drying, and finally scraping with a wire brush. Moreover, the effect only lasts for about a year and a half, so repainting is necessary.
また、この発生した藻が付着する場所は、特に屋外円形沈殿池の越流ノッチと沈殿池の処理水が越流ノッチを通じて流出するトラフである。
そして、藻が付着した場所毎においても色々な藻の除去装置が存在する。
例えば、越流堰内へ下向きに伸びるブラシ支えステーの下端に（ブラシ取付板を介して）ブラシが取り付けられていてブラシ支えステーの上部に設けられたハンドルを回転させ越流堰内の藻を除去する除去装置（特許文献１）、断面Ｔ形で脚部長手方向にトラフを添着した浄化槽隔壁へ附設され、隔壁上面を長手方向移送可能な枠体と、枠体側面へ垂直に固着したガイド棒と、ガイド棒に沿い昇降可能な滑子と、枠体に附設されモータとクランク軸と連杆とから成る滑子の昇降装置と、背面を滑子に固着された樋形ホルダと、中央部でホルダに枢着され隔壁の所要面へ当接可能なブラシを下端に備えるアームと、アーム上端部を螺合貫通してホルダ底面を押圧可能な調節ボルトと、アームと対向して枠体に附設され両者で隔壁を挾持可能なガイド輪装置とから構成された浄化槽隔壁のブラシ掛け装置（特許文献２）等である。
Furthermore, the areas where this algae grows tend to attach are the overflow notch of the outdoor circular sedimentation tank and the trough through which the treated water from the sedimentation tank flows out.
Furthermore, there are various algae removal devices depending on the location where the algae have attached.
For example, there is a removal device (Patent Document 1) in which a brush is attached (via a brush mounting plate) to the lower end of a brush support stay that extends downward into the overflow weir, and a handle provided on the upper part of the brush support stay is rotated to remove algae from inside the overflow weir, and there is a brushing device for a septic tank partition wall (Patent Document 2) which is attached to a septic tank partition wall with a T-shaped cross section and troughs attached in the longitudinal direction of the legs, and consists of a frame that can be moved longitudinally along the upper surface of the partition wall, a guide rod fixed perpendicularly to the side of the frame, a slider that can move up and down along the guide rod, a slider lifting device attached to the frame and consisting of a motor, a crankshaft and a connecting rod, a trough-shaped holder whose back is fixed to the slider, an arm that has a brush at its lower end that is pivotally attached to the holder in the center and can contact the required surface of the partition wall, an adjustment bolt that can screw through the upper end of the arm and press the bottom surface of the holder, and a guide wheel device attached to the frame opposite the arm and capable of gripping the partition wall together.
上記先行技術は、何れも藻が付着した場所やブラシ掛けの構造が異なる。
円形沈殿池は土木工事によるコンクリートを用いて製作されていることから、円形沈殿池の沈殿池の処理水が越流ノッチを通じて流出するトラフである躯体の表面に数ｍｍから、ときには数十ｍｍ程度の凹凸が生じる事がある。そのために、円形沈殿池の躯体の凸凹に対してブラシが追従できないことから藻の掻き残しが生じてしまう。
また経時劣化により凹凸の大きさや深さが深くなるとブラシが凹凸の内部まで届かないため藻の掻き残しが生じてしまう。
The aforementioned prior art methods all differ in the location where the algae are attached and the structure of the brushing process.
Because circular sedimentation tanks are constructed using concrete from civil engineering works, the surface of the structure, which is the trough through which the treated water from the sedimentation tank flows out through the overflow notch, can have irregularities ranging from a few millimeters to sometimes several tens of millimeters. As a result, brushes cannot follow the irregularities of the circular sedimentation tank structure, leaving behind algae.
Furthermore, as the surface deteriorates over time, the size and depth of the unevenness increase, preventing the brush from reaching the inside of the unevenness, resulting in some algae being left behind.
本発明は、上記の課題に鑑みてなされたものであり、発生した藻が付着する円形沈殿池の越流ノッチや処理水が流出するトラフ等の躯体においてブラシで藻を除去する除藻装置を提供することを目的とする。
また、コンクリートを用いて製造されている円形沈殿池の躯体の凹凸に付着した藻を除去することを目的とする。
The present invention has been made in view of the above problems, and aims to provide an algae removal device that removes algae with a brush from structures such as the overflow notch of a circular sedimentation tank where algae grow and adhere, and the trough through which treated water flows.
Furthermore, the purpose is to remove algae that have adhered to the uneven surfaces of the circular sedimentation tank, which is manufactured using concrete.

In Figures 1 to 9,
1 is a circular sedimentation tank, 2 is a trough, 3 is an overflow notch (wear plate), and 4 is a water storage tank (or septic tank).
The trough from which the treated water from the circular sedimentation tank 1 flows out consists of an annular bottom wall 2b, an annular side wall 2a erected thereon, and an overflow side trough wall 2c.
The upper edge of the overflow trough side wall 2c is provided with a sawtooth-shaped overflow notch 3, which allows clean water from the upper layer to slowly and evenly overflow from the entire reservoir to the outside, preventing sludge and other sediment from being stirred up from the bottom of the reservoir 4.
10 is a passage located above the circular sedimentation tank 1, 20 is a center scraper (sludge scraper), 21 is a drive unit, and 22 is a center cage.
The passage 10 provided in the circular sedimentation tank 1 is used for water quality testing in the water storage tank 4, as well as for inspection and repair of the center scraper 20 and drive unit 21.
30 is a support pole for the algae removal brush, 31 is an arm for the algae removal brush, 32 is an adjustment plate, 33 is a guide rod support member, 34 is a guide rod, 35 is a support plate, 36 is a base for the algae removal brush, 37 is an algae removal brush for the central bottom, 38 is a bracket for the algae removal brush for the side bottom, and 39 is an algae removal brush for the side bottom.
前記側部底用除藻ブラシ３９は、三角形状に構成されているので円形沈殿池１のトラフ２の底壁２ｂの角部の藻まで除去することができる。
前記ガイド棒支持部材３３は、長穴を設けた調整板３２にボルト、ナット及びワッシャ等の固定具４０でトラフ幅方向の位置を調整できるように除藻ブラシ用アーム３１に取付けられている。なお、以降に記述の固定具も、ナット及びワッシャを用いた例として記述する。また前記ガイド棒支持材３３にはガイド棒３４が取り付けられていて、ガイド棒３４には回動用ピン３５ａ及び３５ｂを介して支持プレート３５が取り付けられている。
そして該支持プレート３５に除藻ブラシ用ベース３６が取付けられている。
このような構成によりガイド棒支持部材３３のトラフ幅方向の位置を調整することで除藻ブラシ用ベース３６の左右の位置を調整することができ、これにより中央底用除藻ブラシ３７や側部底用除藻ブラシ３９の左右の位置を調整することができる。
Since the side bottom algae removal brush 39 is configured in a triangular shape, it can remove algae from the corners of the bottom wall 2b of the trough 2 of the circular sedimentation tank 1.
The guide rod support member 33 is attached to the algae removal brush arm 31 so that its position in the trough width direction can be adjusted using fasteners 40 such as bolts, nuts, and washers on an adjustment plate 32 provided with an elongated hole. The fasteners described below will also be described as examples using nuts and washers. A guide rod 34 is attached to the guide rod support member 33, and a support plate 35 is attached to the guide rod 34 via pivoting pins 35a and 35b.
A base 36 for the algae removal brush is attached to the support plate 35.
With this configuration, the left and right positions of the algae removal brush base 36 can be adjusted by adjusting the position of the guide rod support member 33 in the trough width direction, thereby allowing the left and right positions of the central bottom algae removal brush 37 and the side bottom algae removal brushes 39 to be adjusted.
また、前記除藻ブラシ用ベース３６は、ガイド棒支持部材３３からワイヤー４１で吊られており、底壁２ｂの底面の凹凸に応じて除藻ブラシ用ベース３６が上下した際に、ワイヤー４１の長さを調節することで、除藻ブラシ用ベース３６に設けられたブラシ（３７、３９等）の刷掃力を一定以上に保持してブラシが折れ曲がらずに移動できる。ブラシが折れ曲がりすぎるとブラシの先端が刷掃面にうまく引っ掛からず刷掃力が弱まってしまうので、ブラシの先端を刷掃面に立てて刷掃力を保持させるのである。 Furthermore, the algae-removing brush base 36 is suspended from the guide rod support member 33 by a wire 41. When the algae-removing brush base 36 moves up and down according to the unevenness of the bottom surface of the bottom wall 2b, the length of the wire 41 is adjusted to maintain a certain level of brushing force for the brushes (37, 39, etc.) on the algae-removing brush base 36, preventing the brushes from bending. If the brushes bend too much, the tips of the brushes will not properly catch on the brushing surface, weakening the brushing force. Therefore, the tips of the brushes are positioned upright on the brushing surface to maintain the brushing force.
さらに、除藻ブラシ用ベース３６には回動用ピン３５ａ及び３５ｂを介して支持プレート３５が取付けられおり、底壁２ｂの底面の凹凸に応じて除藻ブラシ用ベース３６が上下動した際、回動用ピン３５ａ及び３５ｂが図８に示す方向に回動する。除藻ブラシ用ベース３６に取り付けられた中央底用除藻ブラシ３７と側部底用除藻ブラシ３９に加え、除藻ブラシ用ベース３６に装着されている他の部品を含めた自重で底壁２ｂの底面の凹凸に沿って中央底用除藻ブラシ３７と側部底用除藻ブラシ３９を押圧することにより、凹凸のある底壁２ｂの底面を隈なく刷掃することができることとなる。 Furthermore, a support plate 35 is attached to the algae removal brush base 36 via pivot pins 35a and 35b. When the algae removal brush base 36 moves up and down in accordance with the unevenness of the bottom surface of the bottom wall 2b, the pivot pins 35a and 35b rotate in the direction shown in Figure 8. The combined weight of the central bottom algae removal brush 37 and side bottom algae removal brushes 39, along with other components attached to the algae removal brush base 36, presses the central bottom algae removal brush 37 and side bottom algae removal brushes 39 along the unevenness of the bottom surface of the bottom wall 2b, allowing for thorough cleaning of the uneven bottom surface of the bottom wall 2b.
５０は越流側トラフ側壁斜面用除藻ブラシ５１と越流側トラフ側壁上面用除藻ブラシ５２を取付ける越流側トラフ除藻ブラシ用ベースであり、取付板５３と支持軸５４とにより前記除藻ブラシ用ベース３６に取付けられている。
このように、前記越流側トラフ除藻ブラシ用ベース５０は取付板５３を介して除藻ブラシ用ベース３６と繋がっているので除藻ブラシ用ベース３６の左右の移動に応じて越流側トラフ側壁斜面用除藻ブラシ５１と越流側トラフ側壁上面用除藻ブラシ５２が左右に移動できる。
また、前記越流側トラフ除藻ブラシ用ベース５０は、ガイド棒支持部材３３とワイヤー５５で吊られており、越流側トラフ側壁上面２ｄ、越流側トラフ側壁斜面２ｅの凹凸に応じて越流側トラフ除藻ブラシ用ベース５０が上下動した際、ワイヤー５５の長さを調節することで、越流側トラフ除藻ブラシ用ベース５０に設けられたブラシ（５１、５２）の刷掃力を一定以上に保持してブラシが折れ曲がらずに移動できる。
Reference numeral 50 denotes a base for the overflow-side trough algae removal brush, to which the overflow-side trough side wall slope brush 51 and the overflow-side trough side wall upper surface algae removal brush 52 are attached. It is attached to the algae removal brush base 36 by a mounting plate 53 and a support shaft 54.
As described above, the base 50 for the overflow trough algae removal brush is connected to the base 36 for the algae removal brush via the mounting plate 53, so that the algae removal brush 51 for the slope of the overflow trough side wall and the algae removal brush 52 for the upper surface of the overflow trough side wall can move left and right in accordance with the left and right movement of the base 36 for the algae removal brush.
Furthermore, the base 50 for the overflow side trough algae removal brush is suspended by a guide rod support member 33 and a wire 55. When the base 50 for the overflow side trough algae removal brush moves up and down in accordance with the unevenness of the upper surface 2d and the slope 2e of the overflow side trough side wall, the length of the wire 55 can be adjusted to maintain a certain level of brushing force for the brushes (51, 52) provided on the base 50 for the overflow side trough algae removal brush, allowing the brushes to move without bending.
６０はサイド除藻ブラシ用ブラケット、６１はサイド除藻ブラシ、６２は調整板、６３は固定具である。
前記サイド除藻ブラシ用ブラケット６０は、長穴を設けた調整板６２に固定具６３により位置を調整できるように除藻ブラシ用ベース３６に取付けられているので、サイド除藻ブラシ６１の左右方向の位置調整ができる。
また、前記サイド除藻ブラシ用ブラケット６０は、ガイド棒支持部材３３からワイヤー４１で吊られている除藻ブラシ用ベース３６に取り付けられており、底壁２ｂの底面の凹凸による該除藻ブラシ用ベース３６の上下移動に応じてサイド用除藻ブラシ６１の上下方向の移動が可能である。
60 is a bracket for the side algae removal brush, 61 is the side algae removal brush, 62 is an adjustment plate, and 63 is a fixing device.
The bracket 60 for the side algae-removing brush is attached to the base 36 for the algae-removing brush so that its position can be adjusted by fasteners 63 on an adjustment plate 62 with an elongated hole, allowing the position of the side algae-removing brush 61 to be adjusted in the left-right direction.
Furthermore, the bracket 60 for the side algae-removing brush is attached to the base 36 for the algae-removing brush, which is suspended by a wire 41 from the guide rod support member 33. The side algae-removing brush 61 can move vertically in accordance with the vertical movement of the base 36 due to the unevenness of the bottom surface of the bottom wall 2b.
さらに、除藻ブラシ用ベース３６に支持プレート３５を介して接続されているガイド棒３４は、図９に示すように水平方向に回動可能であり、環状の側壁２ａの面と越流側トラフ側壁面２ｆの凹凸に応じて除藻ブラシ用ベース３６がトラフ幅方向の左右に動こうとすると、ガイド棒３４が回動する。従って、除藻ブラシ用ベース３６に設けられたサイド用除藻ブラシ６１、側部底用除藻ブラシ３９および越流側トラフ側壁斜面用除藻ブラシ５１が環状の側壁２ａの面と越流側トラフ側壁面２ｆ並びに越流側トラフ側壁斜面２ｅの凹凸に応じてトラフ幅方向に動くので、凹凸のある環状の側壁２ａの面、越流側トラフ側壁面２ｆ及び越流側トラフ側壁斜面２ｅを隈なく刷掃することができることとなる。
なお、前記〔００１６〕で記述している回動用ピン３５ａ及び３５ｂ並びにガイド棒３４での回動機構は、除藻ブラシ用ベース３６を牽引する支持プレート３５並びに回動用ピン３５ａ及び３５ｂの部分を、ロープ等に代替することでもよい。
Furthermore, the guide rod 34, which is connected to the algae removal brush base 36 via a support plate 35, is rotatable horizontally as shown in Figure 9. When the algae removal brush base 36 attempts to move left or right in the trough width direction in accordance with the irregularities of the annular side wall 2a and the overflow side trough side wall surface 2f, the guide rod 34 rotates. Therefore, the side algae removal brush 61, the side bottom algae removal brush 39, and the overflow side trough side wall slope algae removal brush 51 provided on the algae removal brush base 36 move in the trough width direction in accordance with the irregularities of the annular side wall 2a, the overflow side trough side wall surface 2f, and the overflow side trough side wall slope 2e, so that the irregularities of the annular side wall 2a, the overflow side trough side wall surface 2f, and the overflow side trough side wall slope 2e can be thoroughly cleaned.
Furthermore, the rotation mechanism of the rotating pins 35a and 35b and the guide rod 34 described in [0016] above may be modified by replacing the support plate 35 that pulls the algae removal brush base 36 and the rotating pins 35a and 35b with ropes or the like.
７０は前記除藻ブラシ用アーム３１に接続された越流ノッチ除藻ブラシ用ベース、７１は越流ノッチ除藻ブラシ用ブラケット、７２は越流ノッチ除藻ブラシ、７３は固定具である。
前記越流ノッチ除藻ブラシ用ブラケット７１には長穴が設けられて、前記越流ノッチ除藻ブラシ用ベース７０に固定具７３により位置を調整できるように移動可能に取付けられている。
これにより越流ノッチ除藻ブラシ７２の上下方向の位置調整ができる。
70 is the base for the overflow notch algae removal brush connected to the algae removal brush arm 31, 71 is the bracket for the overflow notch algae removal brush, 72 is the overflow notch algae removal brush, and 73 is the fixing device.
The bracket 71 for the overflow notch algae removal brush is provided with an elongated hole and is movably attached to the base 70 for the overflow notch algae removal brush by a fixing device 73 so that its position can be adjusted.
This allows for vertical position adjustment of the overflow notch algae removal brush 72.
図８及び図９は本発明の円形沈殿池における除藻装置の使用方法を表す図で、図８は側面から見た図であり、図９は図８の平面図である。
図８に示すように駆動装置２１によりセンタースクレーパー２０を回転させると、該センタースクレーパー２０に接続されている除藻ブラシ用サポートポール３０に接続されている除藻ブラシ用アーム３１が回転する。
そして除藻ブラシ用アーム３１が回転すると、除藻ブラシ用アーム３１に調整板３２と固定具４０により移動可能に取付けられているガイド棒支持部材３３が除藻ブラシ用アーム３１の回転と同じ方向に回転する。
このガイド棒支持部材３３が回転すると、該ガイド棒支持部材３３接続されているガイド棒３４、該ガイド棒３４と支持プレート３５を介して接続されている除藻ブラシ用ベース３６が同じ方向に回転する。
Figures 8 and 9 illustrate the method of using the algae removal device in the circular sedimentation tank of the present invention. Figure 8 is a side view, and Figure 9 is a plan view of Figure 8.
As shown in Figure 8, when the center scraper 20 is rotated by the drive device 21, the algae removal brush arm 31, which is connected to the algae removal brush support pole 30 connected to the center scraper 20, rotates.
As the algae-removing brush arm 31 rotates, the guide rod support member 33, which is movably attached to the algae-removing brush arm 31 by an adjustment plate 32 and a fixing device 40, rotates in the same direction as the rotation of the algae-removing brush arm 31.
When the guide rod support member 33 rotates, the guide rod 34 to which the guide rod support member 33 is connected, and the algae removal brush base 36, which is connected to the guide rod 34 via the support plate 35, rotate in the same direction.
そして、除藻ブラシ用ベース３６が回転すると、該除藻ブラシ用ベース３６を介して接続されている中央底用除藻ブラシ３７、側部底用除藻ブラシ３９、越流側トラフ側壁斜面用除藻ブラシ５１、越流側トラフ側壁上面用除藻ブラシ５２及びサイド用除藻ブラシ６１が同じ方向に回転する。
これにより、円形沈殿池の環状の側壁２ａ、環状の底壁２ｂ、越流側トラフ側壁上面２ｄ、越流側トラフ側壁斜面２ｅおよび越流側トラフ側壁面２ｆに付着した藻を除去することができる。
同様に、前記除藻ブラシ用アーム３１が回転すると、該除藻ブラシ用アーム３１に接続された越流ノッチ除藻ブラシ用ベース７０に取付けられた越流ノッチ除藻ブラシ用ブラケット７１が同じ方向に回転するので該越流ノッチ除藻用ブラケット７１に取付けられた越流ノッチ除藻ブラシ７２が同じ方向に回転する。
これにより、円形沈殿池の越流ノッチ３や処理水が流出するトラフ２等の躯体に付着した藻を除去することができる。
As the algae removal brush base 36 rotates, the central bottom algae removal brush 37, the side bottom algae removal brush 39, the overflow side trough side wall slope algae removal brush 51, the overflow side trough side wall upper surface algae removal brush 52, and the side algae removal brush 61, all connected via the algae removal brush base 36, rotate in the same direction.
This makes it possible to remove algae attached to the annular side wall 2a, the annular bottom wall 2b, the upper surface 2d of the overflow side trough side wall, the slope 2e of the overflow side trough side wall, and the surface 2f of the overflow side trough side wall of the circular sedimentation tank.
Similarly, when the algae removal brush arm 31 rotates, the overflow notch algae removal brush bracket 71, which is attached to the overflow notch algae removal brush base 70 connected to the algae removal brush arm 31, rotates in the same direction, causing the overflow notch algae removal brush 72, which is attached to the overflow notch algae removal bracket 71, to rotate in the same direction.
This makes it possible to remove algae attached to the structure of the circular sedimentation tank, such as the overflow notch 3 and the trough 2 through which treated water flows.
