Description

本発明は、液体から固体を分離するために使用される沈殿物掻寄機及びその改修方法に関するものである。   The present invention relates to a sediment scraping machine used for separating a solid from a liquid and a method for repairing the same.

液体と固体の分離は、下水、し尿、工場廃水、上水処理においてだけでなく、工場の生産工程等においても重要な操作の一つである。液体と固体の分離には沈殿池が用いられる。そして沈殿池の底に沈殿した沈殿物を除去するために沈殿物掻寄機が設置される。即ち、民間工場の排水処理施設や、官公庁汚水下水道施設等で使用される沈殿池では、固液分離した沈殿物（沈殿汚泥）を掻き集めて系外に搬出する等のために沈殿物掻寄機が利用されている。   Separation of liquid and solid is one of important operations not only in the treatment of sewage, human waste, factory wastewater and clean water, but also in the production process of the factory. A sedimentation basin is used to separate liquid and solid. A sediment scraper is installed to remove the sediment deposited on the bottom of the sedimentation basin. In other words, in sedimentation ponds used in wastewater treatment facilities of private factories and public sewage sewerage facilities, sediment scrapers are used to collect the solid-liquid separated sediment (sediment sludge) and transport it outside the system. Is being used.

従来、この種の沈殿物掻寄機は、沈殿池の中央部を旋回中心とする旋回アームを具備し、この旋回アームに沈殿池の底に沈殿した沈殿物を掻き寄せるブレード（掻寄部）を取り付け、このブレードで掻き寄せた沈殿物を、この旋回アームに取り付けた吸い上げ用のポンプで吸い上げて配管輸送し、輸送した沈殿物を、沈殿池の外周を囲むように敷設した排泥樋に排出するように構成されている。排泥樋に排出された沈殿物は、排泥樋に接続された排泥ピットに集められ、系外に排出される。   Conventionally, this kind of sediment scraping machine is equipped with a swivel arm centering on the center of the settling basin, and a blade (scratching unit) that scrapes the sediment deposited on the bottom of the settling basin on this swivel arm. The sediment scraped by this blade is sucked up by the suction pump attached to this swivel arm and transported by piping, and the transported sediment is put into a mud drainage laid so as to surround the outer periphery of the sedimentation basin. It is configured to discharge. The sediment discharged to the sludge pit is collected in a sludge pit connected to the sludge throat and discharged outside the system.

しかしながら、上記従来の沈殿物掻寄機においては、以下のような問題があった。
（１）沈殿物掻寄機に供給する電力・制御用の配線や、被処理水に薬品を投入する薬品供給管等は、沈殿池に埋設されている場合が多い。このため、これら配線や配管が老朽化した場合は、その補修や取り替えが困難であった。即ち例えば、沈殿物掻寄機駆動用の電源は、水槽やその下部に埋設された配線よりスリップリングを介して供給されるが、長年の使用による経年劣化等（絶縁低下等）により、緊急停止等のトラブルが発生する恐れがあった。これに対する対策として、取り替え等の施工をしようとしても、古い配線が引き抜けない等のため、前記取り替え等が困難となっていた。同様に、埋設された老朽化した薬品供給管の更新も困難であった。 However, the conventional precipitate scraper has the following problems.
(1) Electric power / control wiring supplied to the sediment scraper and chemical supply pipes for supplying chemical to the water to be treated are often buried in the sedimentation basin. For this reason, when these wiring and piping are aged, it is difficult to repair or replace them. That is, for example, the power source for driving the sediment scraper is supplied via the slip ring from the water tank and the wiring embedded in the lower part of the tank. There was a risk of troubles such as As countermeasures against this, even if an attempt is made to perform replacement or the like, the replacement or the like has become difficult because old wiring cannot be pulled out. Similarly, it has been difficult to renew buried aging chemical supply pipes.

（２）上述のように、沈殿物掻寄機のポンプによって吸い上げた沈殿物を沈殿池外周を囲む排泥樋に排出する構成になっている場合、この排泥樋に排出した沈殿物から臭気（排泥臭気）が発生して沈殿池の周囲（近隣住宅等）に拡散してしまう恐れがあった。 (2) As described above, when the sediment sucked up by the pump of the sediment scraping machine is discharged to the waste mud around the outer periphery of the settling basin, the odor is generated from the precipitate discharged into the waste mud. There was a risk that (sewage odor) would occur and spread around the sedimentation basin (neighboring houses, etc.).

本発明は上述の点に鑑みてなされたものでありその目的は、配線や配管が老朽化した際の改修が容易に行え、また臭気が周囲に拡散することを防止できる沈殿物掻寄機及びその改修方法を提供することにある。   The present invention has been made in view of the above points, and the purpose of the present invention is to provide a sediment scraping machine that can be easily repaired when wiring and piping are aged, and that can prevent odors from spreading to the surroundings. The purpose is to provide a repair method.

以上のように構成されている沈殿物掻寄機５００において、被処理水が導入管５３から攪拌部４５内に導入されると、攪拌部４５内で図示しない攪拌板によって攪拌されると共に、薬液供給管５１から薬液（凝集剤）が供給され、その後、内側の整流部４９内に導入される。整流部４９内に導入された被処理水は、上方に向かいながら整流された後、攪拌部４５の上部を越えて沈殿池１０内に導入される。その間、前記薬剤によって固形分の凝集が進行する。   In the sediment scraping machine 500 configured as described above, when the water to be treated is introduced into the stirring unit 45 from the introduction pipe 53, the water is stirred in the stirring unit 45 by a stirring plate (not shown) and the chemical solution A chemical solution (flocculating agent) is supplied from the supply pipe 51 and then introduced into the inner rectification unit 49. The water to be treated introduced into the rectifying unit 49 is rectified while going upward, and then introduced into the sedimentation basin 10 beyond the upper part of the stirring unit 45. Meanwhile, aggregation of solids proceeds by the drug.

沈殿池１０内に導入された被処理水中の凝集された沈殿物は、沈殿池１０の底に沈殿していく。固形分が取り除かれた被処理水（上澄み水）は、図示しない所定の位置で前記側壁１３を乗り越えて次の工程に移送される。一方、沈殿池１０の底に堆積した沈殿物は、駆動装置１３０を駆動することで旋回アーム１１０と共に回転するブレード１２０によって、分岐した各汚泥排出管１４０の先端（下端）近傍に集められる（ブレード１２０は各汚泥排出管１４０の先端近傍に沈殿物を集めるような形状に形成されている）。   The agglomerated precipitate in the water to be treated introduced into the sedimentation basin 10 settles at the bottom of the sedimentation basin 10. The water to be treated (supernatant water) from which the solid content has been removed passes over the side wall 13 at a predetermined position (not shown) and is transferred to the next step. On the other hand, the sediment deposited on the bottom of the sedimentation basin 10 is collected in the vicinity of the tip (lower end) of each branched sludge discharge pipe 140 by the blade 120 that rotates with the swivel arm 110 by driving the driving device 130 (blade). 120 is formed in such a shape as to collect sediment in the vicinity of the tip of each sludge discharge pipe 140).

各汚泥排出管１４０の先端近傍に集められた沈殿物は、各ポンプ１５０を駆動することで汚泥排出管１４０に吸い込まれ、排泥樋１５に排出される。排泥樋１５に排出された汚泥は自然流下によって排泥ピット１７に集められ、次の工程に移送される。   The sediment collected in the vicinity of the tip of each sludge discharge pipe 140 is sucked into the sludge discharge pipe 140 by driving each pump 150 and discharged to the sludge slag 15. The sludge discharged to the sludge slag 15 is collected in the sludge pit 17 by natural flow and transferred to the next process.

次にこの沈殿物掻寄機５００を改修する方法を説明する。改修方法には主として以下の３種類があるので、それぞれについて説明する。なお、以下の説明において、前記沈殿物掻寄機５００と同一又は相当部分には同一符号を付す。なお以下で説明する事項以外の事項については、前記沈殿物掻寄機５００と同様である。   Next, a method for repairing the sediment scraper 500 will be described. There are mainly the following three types of repair methods, and each will be described. In the following description, the same or corresponding parts as those of the precipitate scraper 500 are denoted by the same reference numerals. Note that matters other than those described below are the same as those of the precipitate scraper 500.

〔配線と汚泥排出管の改修〕
上記沈殿物掻寄機５００の配線６７，６９と汚泥排出管１４０とが老朽化してこれらの改修が必要になった場合、以下のようにしてこれらを改修し、図２に示す沈殿物掻寄機１−１とする。即ち、図２に示すように、中央支柱３０上部の旋回支持部６０を改修すると共に、沈殿池１０の上部に新たに架空架台１６０を架け渡す。架空架台１６０は、この例ではＬ字型であり、その一端を、前記改修した中央支柱３０の上部に回転軸受７５を介在して取り付け、他端を、沈殿池１０の外側の地面に固定する。 [Renovation of wiring and sludge discharge pipe]
When the wiring 67, 69 of the sediment scraper 500 and the sludge discharge pipe 140 become obsolete and need to be repaired, they are repaired as follows, and the sediment scraping shown in FIG. Let it be machine 1-1. That is, as shown in FIG. 2, the turning support 60 at the upper part of the central column 30 is repaired, and an aerial mount 160 is newly installed on the upper part of the sedimentation basin 10. The aerial pedestal 160 is L-shaped in this example, and one end thereof is attached to the upper part of the modified central column 30 via a rotary bearing 75 and the other end is fixed to the ground outside the settling basin 10. .

また旋回支持部６０に設置するスリップリング６１は、新規なものに取り換える。即ち、スリップリング６１は、相対的に回転側と静止側になる新規な第１部材６３と第２部材６５で構成する。このスリップリング６１は、第１部材６３を回転側部材として旋回支持部６０側に固定し、第２部材６５を静止側部材として架空架台１６０側に固定する。第１部材６３の中央には上下に貫通する貫通孔６４が設けられている。そして第１部材６３側の電極６３ａには新規な配線６９を接続し、この配線６９を旋回支持部６０から沈殿物掻寄除去部１００に設置したポンプ１５０や駆動装置１３０や図示しない制御盤等に接続する。一方、第２部材６５側の電極６５ａには新規な配線６７を接続し、この配線６７を架空架台１６０を通して沈殿池１０の外部に引き出す。   Further, the slip ring 61 installed on the turning support 60 is replaced with a new one. That is, the slip ring 61 is composed of a novel first member 63 and second member 65 that are relatively on the rotating side and the stationary side. The slip ring 61 fixes the first member 63 as the rotation side member to the turning support portion 60 side, and fixes the second member 65 as the stationary side member to the overhead frame 160 side. A through hole 64 penetrating vertically is provided at the center of the first member 63. A new wiring 69 is connected to the electrode 63a on the first member 63 side, and the wiring 69 is installed in the sediment scraping removal section 100 from the swivel support section 60, a driving device 130, a control panel (not shown), etc. Connect to. On the other hand, a new wiring 67 is connected to the electrode 65 a on the second member 65 side, and this wiring 67 is drawn out of the sedimentation basin 10 through the aerial mount 160.

一方、汚泥排出管１４０も新規なものに付け替える。即ちまず、図１に示す古い汚泥排出管１４０を取り外し、その代りに新規な汚泥排出管１４０を取り付ける。新規な汚泥排出管１４０は、一端側を複数本に分岐して前記ブレード１２０近傍に開口させ、他端側を旋回アーム１１０の部分で１本に集合して旋回アーム１１０から旋回支持部６０内に導入し、上記スリップリング６１の貫通孔６４を貫通させて架空架台１６０に至らせ、この架空架台１６０に沿って沈殿池１０の外部に引き出し、その先端を排泥ピット１７に直接接続する。なお、汚泥排出管１４０の上記スリップリング６１の下部の部分は、回転継手（スイベルジョイント）７１によってその上下の配管を回転自在に接続している。また汚泥排出管１４０の排泥ピット１７に近い部分（立ち下がり部分）には、サイフォンブレーク部１４１が取り付けられ、サイフォン作用によって被処理水が自動的に沈殿池１０内から排水されていくことを防止している。これによって、新規な沈殿物掻寄機１−１への改修が完了する。なお上記改修手順はその一例であり、他の各種異なる改修手順を用いて新規な沈殿物掻寄機１−１に改修しても良いことはいうまでもない（以下の各例においても同様）。   Meanwhile, the sludge discharge pipe 140 is also replaced with a new one. That is, first, the old sludge discharge pipe 140 shown in FIG. 1 is removed, and a new sludge discharge pipe 140 is attached instead. The new sludge discharge pipe 140 has one end branched into a plurality of branches and opened in the vicinity of the blade 120, and the other end is gathered into one at the swivel arm 110, and the swivel arm 110 and the swivel support section 60 Then, the through hole 64 of the slip ring 61 is penetrated to reach the aerial rack 160, pulled out along the aerial rack 160 to the outside of the sedimentation basin 10, and its tip is directly connected to the mud pit 17. In addition, the lower part of the slip ring 61 of the sludge discharge pipe 140 has its upper and lower pipes rotatably connected by a rotary joint (swivel joint) 71. In addition, a siphon break portion 141 is attached to a portion (falling portion) of the sludge discharge pipe 140 close to the sludge pit 17 so that the water to be treated is automatically drained from the settling basin 10 by the siphon action. It is preventing. This completes the renovation of the new sediment scraper 1-1. In addition, the said refurbishing procedure is the example, and it cannot be overemphasized that it may renovate to the new deposit scraping machine 1-1 using other various different refurbishing procedures (it is the same also in each following example). .

以上のようにして改修された沈殿物掻寄機１−１において、沈殿池１０における被処理水の流れは上記沈殿物掻寄機５００の場合と同一なので、その説明は省略する。一方、各ポンプ１５０の駆動によって汚泥排出管１４０に吸い込まれた汚泥は、前記回転継手７１とスリップリング６１の貫通孔６４内を通って架空架台１６０上を移送され、直接排泥ピット１７に集められ、次の工程に移送される。   In the sediment scraper 1-1 refurbished as described above, the flow of water to be treated in the sedimentation basin 10 is the same as that in the case of the sediment scraper 500, and a description thereof will be omitted. On the other hand, the sludge sucked into the sludge discharge pipe 140 by the driving of each pump 150 is transferred on the aerial mount 160 through the rotary joint 71 and the through hole 64 of the slip ring 61 and directly collected in the sludge pit 17. And transferred to the next step.

この実施形態によれば、沈殿池１０の上部に設置した架空架台１６０に、配線６７を架け渡す構成なので、老朽化した配線６７の改修を容易に行うことができる。即ち、改修前の老朽化した配線６７を補修等することなく、別途、新たな配線６７を架空架台１６０を用いて容易に架設することができ、その改修を容易に行うことができる。特に、改修前の配線６７が図１に示すように埋設されている構造であったような場合は、埋設された配線６７は不要となってこれを補修する必要がなくなり、今後のメンテナンス性の向上や、安定した運転に寄与できる。   According to this embodiment, since the wiring 67 is bridged over the aerial rack 160 installed in the upper part of the sedimentation basin 10, the aging wiring 67 can be easily repaired. That is, a new wiring 67 can be easily installed by using the aerial mount stand 160 without repairing the aging wiring 67 before the repair, and the repair can be easily performed. In particular, in the case where the wiring 67 before refurbishment has a structure embedded as shown in FIG. 1, the embedded wiring 67 becomes unnecessary, and it is not necessary to repair this, so that future maintenance is possible. It can contribute to improvement and stable operation.

また汚泥排出管１４０を、架空架台１６０を通して直接沈殿池１０の系外に引き出せるので、沈殿池１０の外周を囲むように排泥樋１５を設置又は既にある排泥樋１５を使用する必要がなくなる。このため、排泥樋１５から発生する臭気の周囲への拡散を確実に防止することができる。   Further, since the sludge discharge pipe 140 can be directly drawn out of the system of the sedimentation basin 10 through the aerial mount 160, it is not necessary to install the sludge slag 15 so as to surround the outer periphery of the sedimentation basin 10 or to use the existing sludge slag 15. . For this reason, the spreading | diffusion to the circumference | surroundings of the odor which generate | occur | produces from the waste mud drench 15 can be prevented reliably.

特に上記実施形態では、スリップリング６１を用いることで、静止側の架空架台１６０から、回転側の沈殿物掻寄除去部１００に容易に電力や信号を供給できるようにしているが、さらに汚泥排出管１４０を回転継手７１によって連結すると共に、スリップリング６１を貫通させたので、回転側の沈殿物掻寄除去部１００から、静止側の架空架台１６０に容易に汚泥を移送することができる。   In particular, in the above-described embodiment, the slip ring 61 is used so that power and signals can be easily supplied from the stationary overhead rack 160 to the rotary sediment scraping removal unit 100. Since the pipe 140 is connected by the rotary joint 71 and the slip ring 61 is penetrated, the sludge can be easily transferred from the rotary deposit scraping removal section 100 to the stationary overhead mount 160.

なおこの実施形態では、改修前の沈殿物掻寄機５００を改修して沈殿物掻寄機１−１を構成することについて説明したが、沈殿物掻寄機５００の改修ではなく、沈殿物掻寄機１−１は全く新たに新設しても良い。新設した沈殿物掻寄機１−１の場合、改修した沈殿物掻寄機１−１でも同様であるが、これが老朽化して配線６７や汚泥排出管１４０を取り換える場合、その改修作業を全て地上において行うことができるので、その改修を容易に行うことができる。このことは、以下の各実施形態においても同様である。   In this embodiment, it has been described that the sediment scraping machine 500 before the repair is modified to configure the sediment scraping machine 1-1. The auxiliary machine 1-1 may be newly established. In the case of the newly installed sediment scraping machine 1-1, the same applies to the repaired sediment scraping machine 1-1. However, when this is aged and the wiring 67 and the sludge discharge pipe 140 are replaced, all the repair work is performed on the ground. Therefore, the repair can be easily performed. The same applies to the following embodiments.

またこの実施形態では、架空架台１６０に配線６９と汚泥排出管１４０とを通したが、配線６９のみを改修するような場合には、配線６９のみを架空架台１６０に通しても良い。同様に、汚泥排出管１４０のみを改修するような場合には、汚泥排出管１４０のみを架空架台１６０に通しても良い。   In this embodiment, the wiring 69 and the sludge discharge pipe 140 are passed through the aerial mount 160. However, when only the wiring 69 is to be repaired, only the wiring 69 may be passed through the aerial mount 160. Similarly, when only the sludge discharge pipe 140 is repaired, only the sludge discharge pipe 140 may be passed through the aerial rack 160.

〔汚泥排出管と薬液供給管の改修〕
次に、上記図１に示す沈殿物掻寄機５００の薬液供給管５１と汚泥排出管１４０とが老朽化してこれらの改修が必要になった場合、以下のようにしてこれらを改修し、図３に示す沈殿物掻寄機１−２とする。即ち、図３に示すように、旋回支持部６０を改修すると共に、沈殿池１０の上部に新たに図２で示したものと同様の架空架台１６０を架け渡す。 [Renovation of sludge discharge pipe and chemical supply pipe]
Next, when the chemical solution supply pipe 51 and the sludge discharge pipe 140 of the sediment scraping machine 500 shown in FIG. 1 become obsolete and need to be repaired, they are repaired as follows. The precipitate scraper 1-2 shown in FIG. That is, as shown in FIG. 3, the turning support portion 60 is repaired, and an aerial pedestal 160 similar to that shown in FIG.

また旋回支持部６０に設置するスリップリング６１は、新規なものに取り換える。即ち、スリップリング６１は、相対的に静止側と回転側になる新規な第１部材６３と第２部材６５で構成する。このスリップリング６１は、第１部材６３を静止側部材として攪拌整流部４０側に固定し、第２部材６５を回転側部材として旋回支持部６０側に固定する。第１部材６３の中央には上下に貫通する貫通孔６４が設けられている。そして第１部材６３側の電極６３ａには改修前（又は新規）の配線６７を接続する。一方、第２部材６５側の電極６５ａには改修前（又は新規）の配線６９を接続する。   Further, the slip ring 61 installed on the turning support 60 is replaced with a new one. That is, the slip ring 61 includes a first member 63 and a second member 65 that are relatively stationary and rotating. The slip ring 61 fixes the first member 63 to the stirring and rectifying unit 40 side as a stationary side member, and fixes the second member 65 to the turning support unit 60 side as a rotating side member. A through hole 64 penetrating vertically is provided at the center of the first member 63. Then, the wiring 67 before the repair (or new) is connected to the electrode 63a on the first member 63 side. On the other hand, the wire 69 before repair (or new) is connected to the electrode 65a on the second member 65 side.

汚泥排出管１４０は新規なものに付け替える。即ちまず、図１に示す古い汚泥排出管１４０を取り外し、その代りに新規な汚泥排出管１４０を取り付ける。新規な汚泥排出管１４０は、一端側を複数本に分岐して前記ブレード１２０近傍に開口させ、その他端側を１本に集合して旋回支持部６０内に導入してから架空架台１６０に至らせ、この架空架台１６０に沿わせて沈殿池１０の外部に引き出し、その先端を排泥ピット１７に挿入する。なお、汚泥排出管１４０は上記スリップリング６１の上部において、回転継手（スイベルジョイント）７１によってその上下の配管を回転自在に接続している。また汚泥排出管１４０の排泥ピット１７に近い部分には、サイフォンブレーク部１４１が取り付けられている。   The sludge discharge pipe 140 is replaced with a new one. That is, first, the old sludge discharge pipe 140 shown in FIG. 1 is removed, and a new sludge discharge pipe 140 is attached instead. The new sludge discharge pipe 140 is branched into a plurality of ends at one end and opened in the vicinity of the blade 120, and the other end is assembled into one and introduced into the swivel support part 60 before reaching the aerial platform 160. Then, it is pulled out of the sedimentation basin 10 along the aerial platform 160 and its tip is inserted into the mud pit 17. In addition, the sludge discharge pipe 140 is rotatably connected to the upper and lower pipes by a rotary joint (swivel joint) 71 at the upper part of the slip ring 61. A siphon break portion 141 is attached to a portion of the sludge discharge pipe 140 close to the waste mud pit 17.

一方、薬液供給管５１も新規なものに付け替える。即ちまず、図１に示す古い薬液供給管５１を取り外し、その代りに新規な薬液供給管５１を取り付ける。新規な薬液供給管５１の一端は、攪拌部４５の天板４７に接続し、その他端側を上記スリップリング６１の貫通孔６４に貫通させてその上部に回転継手（スイベルジョイント）５５を介して薬液受け部５７を取り付け、さらにその上方部分を架空架台１６０に至らせ、この架空架台１６０に沿わせて沈殿池１０の外部に引き出し、その先端を図示しない薬液供給源に接続する。なお、薬液受け部５７は漏斗形状であり、上部が大径の開口５７１となっており、この開口５７１内に架空架台１６０側から延びる薬液供給管５１の先端５１１を設置している。薬液受け部５７の開口５７１内には、前記汚泥排出管１４０が導入され、その中央に前記回転継手７１が設置される。薬液供給管５１の先端５１１は、回転継手７１を避けるように屈曲して開口５７１に対向している。つまり、旋回アーム１１０側に取り付けた汚泥排出管１４０と薬液受け部５７は、それぞれに回転継手７１，５５を設けることで両者が一体に回転するように構成され、且つこれらが一体に回転しても薬液供給管５１の先端５１１から供給される薬液が確実に薬液受け部５７に導入されてその下流側に供給できる構造となっている。これによって、新規な沈殿物掻寄機１−２への改修が完了する。なお、上記古い薬液供給管５１の取り外しは、少なくとも天板４７に接続した部分（及びその近傍部分）のみについて行えばよく、その他の部分はそのまま残しておいても良い。   On the other hand, the chemical solution supply pipe 51 is also replaced with a new one. That is, first, the old chemical solution supply pipe 51 shown in FIG. 1 is removed, and a new chemical solution supply pipe 51 is attached instead. One end of the new chemical solution supply pipe 51 is connected to the top plate 47 of the stirring unit 45, and the other end is passed through the through hole 64 of the slip ring 61, and a rotary joint (swivel joint) 55 is provided on the upper end thereof. The chemical solution receiving portion 57 is attached, and the upper portion thereof reaches the aerial frame 160, is drawn out of the sedimentation basin 10 along the aerial frame 160, and the tip is connected to a chemical solution supply source (not shown). The chemical solution receiving portion 57 has a funnel shape, and an upper portion is a large-diameter opening 571, and the tip 511 of the chemical solution supply pipe 51 extending from the aerial mount base 160 side is installed in the opening 571. The sludge discharge pipe 140 is introduced into the opening 571 of the chemical liquid receiver 57, and the rotary joint 71 is installed at the center thereof. The tip 511 of the chemical solution supply pipe 51 is bent so as to avoid the rotary joint 71 and faces the opening 571. In other words, the sludge discharge pipe 140 and the chemical solution receiving portion 57 attached to the swivel arm 110 side are configured so that both rotate together by providing the rotary joints 71 and 55, respectively, and these rotate together. Also, the chemical liquid supplied from the tip 511 of the chemical liquid supply pipe 51 is reliably introduced into the chemical liquid receiving portion 57 and can be supplied downstream thereof. This completes the renovation of the new sediment scraper 1-2. The old chemical solution supply pipe 51 may be removed only at least in the portion connected to the top board 47 (and its vicinity), and the other portions may be left as they are.

以上のようにして改修された沈殿物掻寄機１−２において、沈殿池１０における被処理水の流れは上記沈殿物掻寄機５００の場合と同一なので、その説明は省略する。一方、各ポンプ１５０の駆動によって汚泥排出管１４０に吸い込まれた汚泥は、回転継手７１を通って架空架台１６０上を移送され、直接排泥ピット１７に集められ、次の工程に移送される。一方、薬液は、架空架台１６０側の薬液供給管５１から薬液受け部５７、回転継手５５、スリップリング６１の貫通孔６４内を通って攪拌部４５に供給される。   In the sediment scraper 1-2 refurbished as described above, the flow of water to be treated in the sedimentation basin 10 is the same as that in the sediment scraper 500, and a description thereof will be omitted. On the other hand, the sludge sucked into the sludge discharge pipe 140 by driving each pump 150 is transferred on the aerial mount 160 through the rotary joint 71, directly collected in the sludge pit 17, and transferred to the next step. On the other hand, the chemical solution is supplied from the chemical solution supply pipe 51 on the aerial gantry 160 side through the chemical solution receiving portion 57, the rotary joint 55, and the through hole 64 of the slip ring 61 to the stirring portion 45.

この実施形態によれば、沈殿池１０の上部に設置した架空架台１６０に薬液供給管５１を架け渡す構成なので、老朽化した薬液供給管５１の改修を容易に行うことができる。特に、改修前の薬液供給管５１が埋設されている構造であったような場合は、埋設された薬液供給管５１は不要となってこれを補修する必要がなくなり、本発明にかかる沈殿物掻寄機１−２の構造に改修することによる効果は大きい。またこの実施形態では、中央支柱３０部分に薬液との攪拌整流部４０を設けているので、架空架台１６０に架け渡した薬液供給管５１から攪拌整流部４０への連結が容易且つ簡素な構造で行え、好適である。   According to this embodiment, since the chemical solution supply pipe 51 is placed over the aerial mount 160 installed in the upper part of the sedimentation basin 10, the aging chemical solution supply pipe 51 can be easily repaired. In particular, in the case where the chemical solution supply pipe 51 before renovation is embedded, the embedded chemical solution supply pipe 51 becomes unnecessary and does not need to be repaired. The effect of the modification to the structure of the auxiliary machine 1-2 is great. Further, in this embodiment, since the stirring rectification unit 40 with the chemical solution is provided in the central support column 30 portion, the chemical solution supply pipe 51 laid over the aerial mount base 160 can be easily connected to the stirring rectification unit 40 with a simple structure. It is possible and suitable.

また汚泥排出管１４０を、架空架台１６０を通して直接沈殿池１０の系外に引き出せるので、沈殿池１０の外周を囲むように排泥樋１５を設置又は既にある排泥樋１５を使用する必要がなくなる。このため、排泥樋１５から発生する臭気の周囲への拡散を確実に防止することができる。   Further, since the sludge discharge pipe 140 can be directly drawn out of the system of the sedimentation basin 10 through the aerial mount 160, it is not necessary to install the sludge slag 15 so as to surround the outer periphery of the sedimentation basin 10 or to use the existing sludge slag 15. . For this reason, the spreading | diffusion to the circumference | surroundings of the odor which generate | occur | produces from the waste mud drench 15 can be prevented reliably.

また、汚泥排出管１４０は、旋回支持部６０内において、回転継手７１によって架空架台１６０側と沈殿物掻寄除去部１００側とが連結され、一方、薬液供給管５１は、旋回支持部６０内において、汚泥排出管１４０の回転に伴って回転し且つ静止側の架空架台１６０側から供給される薬液を受ける薬液受け部５７を有すると共に、この薬液受け部５７の下流側に回転継手５５を連結することで、回転する薬液受け部５７から、静止する被処理水側（沈殿池１０側）に薬液を移送する構成としたので、回転側の沈殿物掻寄除去部１００から静止側の架空架台１６０に容易に汚泥を移送することができると同時に、静止側の架空架台１６０から回転する旋回支持部６０を通して静止する被処理水側に容易に薬液を移送することができる。さらに汚泥排出管１４０の回転に伴って回転し且つ架空架台１６０側から供給される薬液を受ける薬液受け部５７を設けたので、汚泥排出管１４０と薬液供給管５１それぞれの静止側と回転側の連結部分をコンパクトに一体化できる。   The sludge discharge pipe 140 is connected to the aerial gantry 160 side and the sediment scraping removal part 100 side by a rotary joint 71 in the swivel support part 60, while the chemical solution supply pipe 51 is connected to the swivel support part 60. , And a rotary joint 55 is connected to the downstream side of the chemical solution receiving portion 57 and has a chemical solution receiving portion 57 that receives the chemical solution that rotates with the rotation of the sludge discharge pipe 140 and that is supplied from the stationary overhead stand 160 side. By doing so, since the chemical solution is transferred from the rotating chemical solution receiving portion 57 to the stationary water to be treated (precipitation basin 10 side), the stationary-side aerial pedestal from the rotating-side sediment scraping removal portion 100 The sludge can be easily transferred to 160, and at the same time, the chemical solution can be easily transferred to the water to be treated which is stationary through the swivel support portion 60 which rotates from the stationary overhead table 160. Furthermore, since the chemical liquid receiving portion 57 that rotates with the rotation of the sludge discharge pipe 140 and receives the chemical liquid supplied from the aerial mount 160 side is provided, the stationary side and the rotation side of the sludge discharge pipe 140 and the chemical liquid supply pipe 51 respectively. The connecting part can be integrated compactly.

またこの実施形態では、架空架台１６０に汚泥排出管１４０と薬液供給管５１とを通したが、汚泥排出管１４０のみを改修するような場合には、汚泥排出管１４０のみを架空架台１６０に通しても良い。同様に、薬液供給管５１のみを改修するような場合には、薬液供給管５１のみを架空架台１６０に通しても良い。   In this embodiment, the sludge discharge pipe 140 and the chemical solution supply pipe 51 are passed through the aerial mount 160. However, when only the sludge discharge pipe 140 is to be repaired, only the sludge discharge pipe 140 is passed through the aerial mount 160. May be. Similarly, when only the chemical solution supply pipe 51 is to be repaired, only the chemical solution supply pipe 51 may be passed through the aerial mount 160.

〔配線と薬液供給管の改修〕
次に、上記図１に示す沈殿物掻寄機５００の配線６７，６９と薬液供給管５１とが老朽化してこれらの改修が必要になった場合、以下のようにしてこれらを改修し、図４に示す沈殿物掻寄機１−３とする。即ち、図４に示すように、旋回支持部６０を改修すると共に、沈殿池１０の上部に新たに図２で示したものと同様の架空架台１６０を架け渡す。 [Renovation of wiring and chemical supply pipe]
Next, when the wires 67 and 69 of the sediment scraper 500 shown in FIG. 1 and the chemical solution supply pipe 51 have become obsolete and need to be repaired, they are repaired as follows. The precipitate scraper 1-3 shown in FIG. That is, as shown in FIG. 4, the turning support unit 60 is repaired, and an aerial pedestal 160 similar to that shown in FIG.

また旋回支持部６０に設置するスリップリング６１は、新規なものに取り換える。即ち、スリップリング６１は、相対的に回転側と静止側になる新規な第１部材６３と第２部材６５で構成する。このスリップリング６１は、第１部材６３を回転側部材として旋回支持部６０側に固定し、第２部材６５を静止側部材として架空架台１６０側に固定する。そして第１部材６３側の電極６３ａには新規な配線６９を接続し、この配線６９を旋回支持部６０から沈殿物掻寄除去部１００に設置したポンプ１５０や駆動装置１３０や図示しない制御盤等に接続する。一方、第２部材６５側の電極６５ａには新規な配線６７を接続し、この配線６７を架空架台１６０を通して沈殿池１０の外部に引き出す。   Further, the slip ring 61 installed on the turning support 60 is replaced with a new one. That is, the slip ring 61 is composed of a novel first member 63 and second member 65 that are relatively on the rotating side and the stationary side. The slip ring 61 fixes the first member 63 as the rotation side member to the turning support portion 60 side, and fixes the second member 65 as the stationary side member to the overhead frame 160 side. A new wiring 69 is connected to the electrode 63a on the first member 63 side, and the wiring 69 is installed in the sediment scraping removal section 100 from the swivel support section 60, a driving device 130, a control panel (not shown), etc. Connect to. On the other hand, a new wiring 67 is connected to the electrode 65 a on the second member 65 side, and this wiring 67 is drawn out of the sedimentation basin 10 through the aerial mount 160.

一方、薬液供給管５１も新規なものに付け替える。即ちまず、図１に示す古い薬液供給管５１を取り外し、その代りに新規な薬液供給管５１を取り付ける。新規な薬液供給管５１の一端は、攪拌部４５の天板４７に接続し、その他端側を上記スリップリング６１の貫通孔６４に貫通させてその上方部分を架空架台１６０に至らせ、この架空架台１６０に沿わせて沈殿池１０の外部に引き出し、その先端を図示しない薬液供給源に接続する。これによって、新規な沈殿物掻寄機１−３への改修が完了する。なお、上記古い薬液供給管５１の取り外しは、少なくとも天板４７に接続した部分（及びその近傍部分）のみについて行えばよく、その他の部分はそのまま残しておいても良い。   On the other hand, the chemical solution supply pipe 51 is also replaced with a new one. That is, first, the old chemical solution supply pipe 51 shown in FIG. 1 is removed, and a new chemical solution supply pipe 51 is attached instead. One end of the new chemical solution supply pipe 51 is connected to the top plate 47 of the stirring unit 45, the other end is passed through the through hole 64 of the slip ring 61, and the upper part thereof reaches the aerial mount 160, Along with the gantry 160, it is pulled out of the sedimentation basin 10, and its tip is connected to a chemical supply source (not shown). This completes the renovation of the new sediment scraper 1-3. The old chemical solution supply pipe 51 may be removed only at least in the portion connected to the top board 47 (and its vicinity), and the other portions may be left as they are.

以上のようにして改修された沈殿物掻寄機１−３において、沈殿池１０における被処理水の流れは上記沈殿物掻寄機５００の場合と同一なので、その説明は省略する。また各ポンプ１５０の駆動によって汚泥排出管１４０に吸い込まれた汚泥の流れも上記沈殿物掻寄機５００の場合と同一なので、その説明は省略する。一方、薬液は、架空架台１６０側の薬液供給管５１からスリップリング６１の貫通孔６４内を通って攪拌部４５に供給される。   In the sediment scraper 1-3 modified as described above, the flow of water to be treated in the sedimentation basin 10 is the same as that in the sediment scraper 500, and the description thereof is omitted. Moreover, since the flow of the sludge sucked into the sludge discharge pipe 140 by driving each pump 150 is the same as that in the case of the sediment scraper 500, the description thereof is omitted. On the other hand, the chemical liquid is supplied from the chemical liquid supply pipe 51 on the aerial mount base 160 side through the through hole 64 of the slip ring 61 to the stirring unit 45.

この実施形態によれば、沈殿池１０の上部に設置した架空架台１６０に、配線６７と薬液供給管５１とを架け渡す構成なので、老朽化した配線６７や薬液供給管５１の改修を容易に行うことができる。特に、改修前の配線６７や薬液供給管５１が埋設されている構造であったような場合は、これら埋設された配線６７や薬液供給管５１は不要となってこれを補修する必要がなくなり、この場合は特に本実施形態にかかる沈殿物掻寄機１−３の構造に改修することによる効果は大きい。   According to this embodiment, since the wiring 67 and the chemical solution supply pipe 51 are bridged to the aerial mount 160 installed in the upper part of the sedimentation basin 10, the old wiring 67 and the chemical solution supply pipe 51 are easily repaired. be able to. In particular, in the case where the wiring 67 and the chemical solution supply pipe 51 before renovation are embedded, the embedded wiring 67 and the chemical solution supply pipe 51 are unnecessary, and it is not necessary to repair them. In this case, in particular, the effect of renovation to the structure of the sediment scraper 1-3 according to the present embodiment is great.

また、配線６７は、スリップリング６１を介して、静止側の架空架台１６０側と、回転側の沈殿物掻寄除去部１００側とが連結されているので、架空架台１６０側から沈殿物掻寄除去部１００側に容易に電源を供給することができ、同時に、薬液供給管５１をスリップリング６１に貫通させたので、装置を一体化できる。   In addition, since the wiring 67 is connected to the stationary overhead rack 160 side and the rotary sediment scraping removal part 100 side via the slip ring 61, the sediment scraping from the overhead rack 160 side. The power can be easily supplied to the removing unit 100 side, and at the same time, since the chemical solution supply pipe 51 is penetrated through the slip ring 61, the apparatus can be integrated.

またこの実施形態では、架空架台１６０に配線６７と薬液供給管５１とを通したが、配線６７のみを改修するような場合には、配線６７のみを架空架台１６０に通しても良い。同様に、薬液供給管５１のみを改修するような場合には、薬液供給管５１のみを架空架台１６０に通しても良い。   In this embodiment, the wiring 67 and the chemical solution supply pipe 51 are passed through the aerial pedestal 160. However, when only the wiring 67 is to be repaired, only the wiring 67 may be passed through the aerial pedestal 160. Similarly, when only the chemical solution supply pipe 51 is to be repaired, only the chemical solution supply pipe 51 may be passed through the aerial mount 160.
