Description

【０００１】
【発明の属する技術分野】
本発明は、主として車両の軸箱等の洗浄に際して洗浄後排出される高粘度沈着廃棄物（例えば、リチュウムグリスを含むスラッジ等）、などの汚泥を含む洗浄廃液の再生処理を行う高粘度廃棄物を含有する洗浄廃液の再生処理装置に関する。
【０００２】
【従来の技術】
（１）従来の洗浄廃液の濾過処理方法として、例えば、図１０に示すように不織布フイルターを用いた濾過装置が知られる。
【０００３】
この装置は処理液受槽の上部にメッシュコンベアを配設し、ロール状に巻き取られたフイルターエレメントとなる不織布フィルタをメッシュコンベアの上流側から供給可能に設置した構成となっている。
【０００４】
不織布フイルターはメッシュコンベア上に延べ状態に載置して、メッシュコンベアの動きと共に、不織布フイルターは移動しコンベアの後端で自由落下し、容器の中に回収されるようになっている。
【０００５】
被処理液は前記メッシュコンベアの中間でこの不織布フイルター上へ注がれ、濾過された処理済み液は前記メッシュコンベア下方の貯液槽へ回収される（以上は、改良前の既存技術につき文献はない。）。
【０００６】
（２）また、他の例として、金属切粉回収時における切削液の酸欠を防止して、その再利用を可能とする固液分離装置が開示されている。
【０００７】
即ち、原動機により回転する網目状ドラムを貯液槽上に横設し、該網目状ドラムの外部より内部へ通ずる固液流入口を開設し、上面に受口を開口させ側方に吐出口を導出させた固分収容体を網目状ドラム内に横設し、固分収容体内に横設された螺旋体を吐出口の導出方向へ伸延させて原動機で駆動される螺旋繰出機構を構成し、かつ、固分収容体から吐出口へ至る間において、内径面を螺旋体の山部外周から谷部へ向けて偏心状に嵌合させた複数枚の可動環状板と、内径面を螺旋体の山部外周へ同心状に嵌合させて枠状の固定体支承される環状間板とを、軸方向へ交互に重合させて積層し、螺旋体が回転することによりその山部外周が可動環状板の内径面を押圧しつつ環状間板の内径面に沿って回転して可動環状板に偏心回転運動を行わせるよう構成されている、というものであり、処理後の切削液に空気を混入させ、酸欠による切削液の劣化を防止して再利用を可能にするというものである（例えば、特許文献１参照。）。

【発明が解決しようとする課題】
然しながら、上述の従来技術において、（１）の場合、洗浄対象部品（以下、ワークと称す）の汚れ具合によって、ワーク洗浄後の処理液に含まれる高粘度沈着廃棄物や汚泥の混濁の割合（スラリーの程度）は一定しない。
【００１０】
また、混濁状況の時間的変化は、洗浄対象ワークの形状や汚れ物の付着具合により一様ではなく、洗浄開始からの経過時間に対しての混濁割合は反比例する傾向にある。すなわち、洗浄開始直後は多量の廃棄物が含有されるが、洗浄時間の経過と共に、含有される廃棄物は減少する。不織布フイルターでの処理能力は、洗浄後の処理液に含まれる高粘度沈着廃棄物及び、汚泥等の含有量と不織布フイルターの供給速度との相関関係で表される。
【００１１】
このために、不織布フイルターの供給速度を最大混濁状態の濾過速度より低下させると、最大混濁状態のときに不織布フイルターの目詰まりが発生し、濾過されるべき物質が不織布フイルターの表面から溢れて流出し、ワーク洗浄後の処理液が処理液受槽へ未処理状態で回収され、洗浄ノズルを詰まらせ、洗浄不可能となる。
【００１２】
また、貯液槽の内壁には、高粘度物質が付着し周期的に清掃しなければならないという不都合な問題がある。従って、不織布フイルターの供給速度は最大混濁状態を想定した濾過可能速度に設定しなければならい。
【００１３】
更に、最大混濁状態を想定して一定速度にて不織布フイルターを供給すれば高粘度沈着廃棄物や汚泥の混濁の割合が低いときには、不必要な不織布フイルターの消費が大量に発生するという問題がある。
【００１４】
（２）の場合は、高粘度廃棄物を含有する洗浄廃液を対象としたとき、装置内に付着したスラッジを除去するのが難しく、且つ構造が複雑であり、高価な装置となり、経済的に問題がある。
【００１５】
本発明は、上述の点に着目して成されたもので、（１）不織布等のフィルタエレメントの浪費を回避し、（２）沈着・粘性のあるスラッジを容易に分離・排出し、洗浄廃液を再生回収可能とするコスト的に有利な高粘度廃棄物を含有する洗浄廃液の再生処理装置を提供することを目的とする。
【００１６】
【課題を解決するための手段】

【００２７】
（実施例１）
以下、実施例１について、図１〜４を参照して説明する。
【００２８】
ワークＷを洗浄後の被処理液の流れの方向をフィルタエレメントＦＥを挟んで内側から外側へ向かう構成とした固液分離用のフィルタエレメントＦＥを周設した筒状回転体を形成するフィルタドラムＤは、筒状に形成された前記フィルタエレメントＦＥの内側面に所定のピッチで前記筒状回転体の軸心に平行に細長状板体を形成するスラッジ係止部材４を突設し、前記筒状回転体の両端部に側板を設け、該側板の一方は支持軸９に嵌合して従動・回動自在とし、側板の他方は被処理液の流入口を少なくとも１以上設けると共に、駆動源１１と接続して主動・回動自在であり、このフィルタドラムＤの上方に平行して洗浄ノズル装置２を設け、この洗浄ノズル装置２は前記フィルタエレメントＦＥを洗浄すると同時に前記フィルタエレメントＦＥからスラッジを剥離させる機能を有し、剥離したスラッジを収容するスラッジ収容体５を有し、該スラッジ収容体５は、断面がＵ字状の樋に疑似形状をしており、前記フィルタドラムＤの内部に別個に固定して支持され、前記洗浄ノズル装置２及び前記スラッジ係止部材４の下方に開口して成り、前記フィルタドラムＤの回転方向に対して前記開口部の前縁部、後縁部に断面円弧状翼部５ｃ、５ｄを有し、前記スラッジ係止部材４は前記断面円弧状翼部５ｃ、５ｄに近接して相対的に摺動に近い状態で移動し、前記スラッジ収容体５外にスラッジが脱落するのを防止する機能を備え、該スラッジ収容体５の底部に設けられて分離処理後の前記スラッジを吐出口へ導出する搬送手段Ｕと、該搬送手段Ｕで搬送されたスラッジを機外へ排出するための排出手段ＥＶとを有し、上記各構成要素となる洗浄装置２、スラッジ収容体５及び搬送手段Ｕを内蔵するスラッジ収容体５、フィルタドラムＤ、等を１つの筐体１内に組み込み、分離処理後の処理液を吸引回収する回収手段（図示略）を備え、回収した処理液を再生可能とする構成としてある。
【００２９】
スラッジ収容体５は、補強を兼ねた仕切り板５ａが適宜設けられ、落下したスラッジを搬送手段Ｕに規制しつつ供給するようになっている。
【００３０】
またスラッジ収容体５の反対側は、補強を兼ね、且つ開口部を有するスラッジ付着板５ｂが適宜配設されている。
【００３１】
搬送手段Ｕは、第１、第２の二条の螺旋方向相反するコイルバネ６、７を両端フリーの棒状体を心材８として重ねて捲回し、第２のコイルバネ（または固定コイルバネ）７の一方は支持軸９に固着し、他方はフリー端とし、第１のコイルバネ（または回転コイルバネ）６は逆向き螺旋状とすると共に、前記第２のコイルバネ７のフリー端側と重なる側を駆動軸１０側に固着し、他方をフリー端とした互いに逆向き螺旋状の二条のコイルバネコンベアとし、且つ前記第１、第２の両コイルバネ６、７のフリー端側の線材先端部を円錐状にカットして成形し、固定・静止した前記第２のコイルバネ７と擦り合いながら逆向き螺旋状の第１のコイルバネ６が摺動回転してスラッジを移動可能に構成してある。
【００３２】
９ａは、支持軸９を筐体１に固定するためのキーである。
【００３３】
Ｊは、フィルタドラムＤが、固定したスラッジ収容体５の周りに回動自在とする、例えば、軸受けメタル等の軸受け部材である。
【００３４】
尚、搬送手段Ｕを構成する第１、第２コイルバネ６、７のフリー端側の線材先端部を円錐状にカットして成形したのは、搬送操作中の回転状態において、抵抗が少なく、且つ引っかかりを回避する為のものである。
【００３５】
Ｓは、フィルタドラムＤと、筐体１との間のシール部材であり、被処理液がフィルタドラムＤの外側に漏れるのを防止している。
【００３６】
洗浄ノズル装置２は、前記フィルタエレメントＦＥを周設した筒状回転体を形成するフィルタドラムＤの直上、且つフィルタドラムＤの軸心に平行して横設し、前記フィルタエレメントＦＥを挟んで外側から内側に向かって洗浄液が噴射可能に洗浄ノズル装置２を組み込んだ筒体３で構成してある。
【００３７】
実施例１における洗浄ノズル装置２のノズル穴３ａは、筒体３の所定部位に、例えば、ドリル等で穿設した穴の場合である。
【００３８】
スラッジを機外へ排出するための排出手段ＥＶは、循環回転するチェーン２０にスラッジ保持用板状体１６を片持ち状態でバネ部材１６ａを介して可傾自在に取り付け、ケーシング１７の遠心方向側壁に前記バネ部材１６ａに抗して押圧し、摺動しながら移動し、排出口１９直前（図４の符号１９ａ）で押圧状態から解放され、前記バネ部材１６ａの反力でスラッジ保持用板状体１６は煽り動作を行うと同時に、前記スラッジ保持用板状体１６のスラッジを掻き取るための掻き取り部材１８を設けた排出口１９へスラッジを排出する構成としてある。
【００３９】
スラッジ保持用板状体１６は、図４に示すように、先端部１６ｃを丸めて引っ掛かりをなくし、チェーン取り付け部のバネ付き蝶番側の端部１６ｂでストッパーの役目をするように折り曲げてある。
【００４０】
また、排出手段ＥＶのスラッジ保持用板状体１６とケーシング１７との寸法関係は、図示するように、排出口１９の直前の１９ａの位置までは、スラッジ保持用板状体１６の長さ寸法Ｗ_０よりもケーシング１７の寸法Ｗ_１は小さく、スラッジの排出が終って下降する状態になったとき、ケーシング１７の寸法Ｗ_２はＷ_０よりも大となる。即ち、Ｗ_１＜Ｗ_０≦Ｗ_２の関係を有する。
【００４１】
また、実施例１におけるスラッジ保持用板状体１６は、剛性の金属製または合成樹脂製とした場合である。
【００４２】
チェーン２０は、駆動源１１に接続され、駆動軸１０に周設された駆動側スプロケット１５と従動側スプロケット１５′に張設され、図示のように矢印「ヘ」の方向に回転駆動する。
【００４３】
上述の構成及び図面に基づいて作用を説明する。
【００４４】
洗浄対象物となるワークＷを所定位置に搬送停止し、洗浄液で洗浄され、洗浄後の被処理液を、流入口１２より導入し、図１中の矢印「イ」に沿って筐体１内に供給され、スラッジ収容体５の下方反対側の付着板５ｂ側を矢印「ロ」に沿って流動し、複数の付着板５ｂに交互に切欠いてある開口部を経由しながらスラッジ、スラリー及び懸濁粒子同士の衝突によりフロックが成長し、網目状のフィルタエレメントＦＥに補足されやすくなり、スラッジ係止部材４に係止されてフィルタドラムＤの回転に伴い上昇してスラッジ収容体５の開口縁部の頂上に達したときにフィルタドラムＤのフィルタエレメントＦＥの外周面より洗浄用のノズル穴３ａからの再生処理後の清澄液噴射でスラッジ収容体５内に落下させる。
【００４５】
回転しているフィルタドラムＤの不織布等の網目状のフィルタエレメントＦＥの内側に突設しているスラッジ係止部材４にスラッジが係止されて運ばれ、スラッジ係止部材４に係止されたスラッジは、スラッジ収容体５の前縁部に断面円弧状翼部５ｃを設けたことで、フィルタドラムＤの回転と共に、図３に示す矢印「ホ」の方向に上昇移動する際、スラリー、スラッジがスラッジ収容体５の開口部に達する以前の落下を防止し、かつ、スラッジ収容体５の開口部より下降方向にもスラッジ収容体５の後縁部に断面円弧状翼部５ｄを設けたことで、開口部からの処理液の流出圧力を抑制し網目状のフィルタエレメントＦＥに付着したフロックの再粒子化を防止しすることが出来る。さらに、フィルタドラムＤの外周面より洗浄用ノズル穴３ａでの清澄液噴射からスラリーの飛散を防止し、確実なスラッジの落下を促進する役目をする。
【００４６】
スラッジ係止部材４は、フィルタドラムＤの回転と共に、更に矢印「ホ」の方向に移動し、スラッジ収容体５の後縁部に設けられた断面円弧状翼部５ｄに近接して摺動に近い状態で移動し、洗浄後の濾過された上澄み液が、例えば不織布（または網目状ネット等）のフィルタエレメントＦＥを通過してフィルタドラムＤの外側に流れ、図１に示す矢印「ハ」の方向に進み、更に矢印「ニ」の方向へ不図示の吸引手段により吸引回収される。
【００４７】
スラッジ収容体５内に貯留され、底部に内蔵された搬送手段Ｕの回転駆動によって、第１のコイルバネ（回転コイルバネ）６が固定されている第２のコイルバネ（固定コイルバネ）７及び両端フリーの棒状体を形成する心材８の表面をしごくように擦りながら回転・摺動してスラッジを出口１３へ導出する。
【００４８】
一方、搬送手段Ｕの作用により出口１３に導出されたスラッジは、駆動源１１に接続された駆動軸１０に周設され、駆動側スプロケット１５と従動側スプロケット１５′に張設されて回転・移動するチェーン２０に所定ピッチで、且つ片持ち状態でバネ部材１６ａを介して可傾自在に取り付けられたスラッジ保持用板状体１６に保持され、図４に示すように、矢印「ヘ」の方向に進み、ケーシング１７の遠心方向側壁に前記バネ部材１６ａに抗して押圧し、摺動しながら移動し、排出口１９直前の１９ａの位置で押圧状態から解放され、前記バネ部材１６ａの反力でスラッジ保持用板状体１６は煽り動作を行うと同時に、スラッジを掻き取るための掻き取り部材１８により、スラッジ保持用板状体１６に保持されたスラッジは掻き落とされ、排出口１９から排出される。
【００４９】
尚更に説明を加えると、固着してある固定コイルバネ７の根元付近では回転コイルバネ６のフリーの先端は最大の撓みを発生するが、コイルの内側へ嵌装した棒状体を形成する心材８によって公転軌跡の逸脱を抑制することが出来る。
【００５０】
回転コイルバネ６の線材を円錐形状に成形した先端は、固定コイルバネ７へ乗り上がり回転と、潜り込み回転を容易にし、固定コイルバネ７の周りを公転する。
【００５１】
また、回転コイルバネ６は、駆動軸１０に固着されている根元付近では固定コイルバネ７のフリーの先端は最大の撓みを発生するが、コイルの内側に嵌装した棒状体を形成する心材８で公転軌跡の逸脱を抑制することが出来る。
【００５２】
固定コイルバネ７の線材を円錐形状に成形した先端が乗り上がりと潜り込みを容易にし、回転コイルバネ６の周りを公転することで回転コイルバネ６の内周と固定コイルバネ７の外周とが接し、回転コイルバネ６の外周と固定コイルバネ７の内周とが接し、回転コイルバネ６の内周と固定コイルバネ７の内周とが棒状体を形成する心材８の外周に接し、回転コイルバネ６の周りと固定コイルバネ７の周りと心材８の周りとに付着したスラッジ及びスラリーを混合しながら吐出方向へそぎ送りすることが出来る。
【００５３】
そして、外部の吸引ポンプ（図示略）により筐体１の端面壁に突設されている排出口１４より網目を通過した清澄な液は外部の貯液タンク（図示略）に排出され、フィルタドラムＤの外周面から洗浄用ノズル穴３ａよりの清澄液噴射は外部の貯液タンクより送液ポンプ（図示略）で連続して行われる。
【００５４】
（実施例２）
実施例２では、実施例１と異なる部分を説明し、同様な部分は説明を省略する。
【００５５】
実施例２は、洗浄ノズル装置２を実施例１の場合と異なるものとした例である。

【００５７】

【００５８】
尚、ノズル板体２０をサンドイッチ状に両側から背中合わせにして挟持する断面倒立Ｌ字状挟持部材２１、２２、及び筒体３を成形する場合、ボルト等で固着・成形し、分解・組み立てが容易な構造としてある。
【００５９】

【００６０】

The present invention relates to a recycling treatment apparatus for cleaning waste liquid containing water.
[0002]
[Prior art]
(1) As a conventional washing waste liquid filtration method, for example, FIG. 10 As shown in FIG. 1, a filtration apparatus using a nonwoven fabric filter is known.
[0003]
This apparatus has a configuration in which a mesh conveyor is disposed in the upper part of the treatment liquid receiving tank, and a non-woven fabric filter serving as a filter element wound up in a roll shape is installed so as to be supplied from the upstream side of the mesh conveyor.
[0004]
The nonwoven fabric filter is placed on the mesh conveyor in a stretched state, and the nonwoven fabric filter moves and freely falls at the rear end of the conveyor and is collected in the container along with the movement of the mesh conveyor.
[0005]
The liquid to be treated is poured onto the non-woven filter in the middle of the mesh conveyor, and the filtered processed liquid is placed under the mesh conveyor. Storage tank (There is no literature on the existing technology before improvement.)

[Problems to be solved by the invention]
However, in the above-described prior art, in the case of (1), the turbidity ratio of the high-viscosity deposition waste and sludge contained in the processing liquid after the workpiece cleaning (depending on the condition of the workpiece to be cleaned (hereinafter referred to as a workpiece)) ( The degree of slurry) is not constant.
[0010]
Further, the temporal change in the turbidity state is not uniform due to the shape of the workpiece to be cleaned and the degree of adhesion of dirt, and the turbidity ratio with respect to the elapsed time from the start of cleaning tends to be inversely proportional. That is, a large amount of waste is contained immediately after the start of washing, but the contained waste decreases as the washing time elapses. The processing capacity of the nonwoven fabric filter is expressed by the correlation between the content of high-viscosity deposition waste and sludge contained in the treated liquid after washing and the supply rate of the nonwoven fabric filter.
[0011]
For this reason, if the supply rate of the nonwoven fabric filter is reduced below the maximum turbidity filtration rate, the nonwoven fabric filter is clogged in the maximum turbidity state, and the material to be filtered overflows from the surface of the nonwoven fabric filter. Then, the processing liquid after the workpiece cleaning is collected in the processing liquid receiving tank in an unprocessed state, and the cleaning nozzle is clogged and cleaning becomes impossible.

In the case of (2), when cleaning waste liquid containing high-viscosity waste is targeted, it is difficult to remove sludge adhering to the inside of the apparatus, the structure is complicated, and the apparatus becomes expensive, economically. There's a problem.
[0015]

It is comprised with the cylinder 3 incorporating the washing nozzle apparatus 2 so that washing | cleaning liquid can be sprayed toward inner side.
[0037]
The nozzle hole 3a of the cleaning nozzle device 2 in the first embodiment is a case of a hole drilled in a predetermined portion of the cylindrical body 3 with, for example, a drill.
[0038]
The discharging means EV for discharging the sludge to the outside of the machine is attached to the circulating and rotating chain 20 in a cantilevered state via a spring member 16a in a cantilevered state, and a centrifugal side wall of the casing 17 is attached. It is pressed against the spring member 16a, moved while sliding, released from the pressed state immediately before the discharge port 19 (symbol 19a in FIG. 4), and sludge holding plate-like by the reaction force of the spring member 16a The body 16 is configured to discharge the sludge to the discharge port 19 provided with the scraping member 18 for scraping off the sludge of the sludge holding plate-like body 16 at the same time as performing the turning operation.
[0039]
As shown in FIG. 4, the sludge holding plate-like body 16 is bent so as to serve as a stopper at the end 16 b of the chain attachment portion on the hinged side with the spring by rounding the tip end portion 16 c to eliminate the catch.
[0040]
Further, the dimensional relationship between the sludge holding plate 16 and the casing 17 of the discharge means EV is such that the length dimension of the sludge holding plate 16 up to the position 19a immediately before the discharge port 19 is shown in the figure. W ₀ Than the dimension W of the casing 17 ₁ Is small, and when the sludge is discharged, the dimension of the casing 17 is reduced. ₂ Is W ₀ Will be greater than. That is, W ₁ <W ₀ ≦ W ₂ Have the relationship.
[0041]
Further, the sludge holding plate-like body 16 in Example 1 is a case where it is made of rigid metal or synthetic resin.
[0042]
The chain 20 is connected to the drive source 11, is stretched between a drive side sprocket 15 and a driven side sprocket 15 ′ that are provided around the drive shaft 10, and is rotationally driven in the direction of arrow “f” as shown in the figure.
[0043]
The operation will be described based on the above-described configuration and drawings.
[0044]
The workpiece W to be cleaned is stopped at a predetermined position, cleaned with the cleaning liquid, and the processed liquid after cleaning is introduced from the inflow port 12, and the inside of the housing 1 along the arrow “I” in FIG. 1. The sludge container 5 flows on the side of the adhering plate 5b on the opposite side of the sludge container 5 along the arrow “b”, and passes through the openings alternately cut in the adhering plates 5b. The floc grows due to the collision between the turbid particles and is easily captured by the mesh-like filter element FE. The flocs are raised by the rotation of the filter drum D by being locked by the sludge locking member 4 and opening edge of the sludge container 5 When reaching the top, the filter drum D is dropped from the outer peripheral surface of the filter element FE into the sludge container 5 by the refining liquid jet from the cleaning nozzle hole 3a after the regeneration process.
[0045]
The sludge is locked and carried by the sludge locking member 4 protruding inside the mesh-like filter element FE such as a nonwoven fabric of the rotating filter drum D, and is locked to the sludge locking member 4. When the sludge is moved upward in the direction of the arrow “E” shown in FIG. Is prevented from falling before reaching the opening of the sludge container 5, and the cross-section arcuate wing 5d is provided at the trailing edge of the sludge container 5 in the downward direction from the opening of the sludge container 5. Thus, the outflow pressure of the processing liquid from the opening can be suppressed and re-particulation of the floc attached to the mesh filter element FE can be prevented. Furthermore, it prevents the slurry from scattering from the clarified liquid jet from the cleaning nozzle hole 3a from the outer peripheral surface of the filter drum D, and promotes the reliable sludge fall.
[0046]
As the filter drum D rotates, the sludge locking member 4 further moves in the direction of the arrow “e”, and slides close to the cross-section arcuate wing 5d provided at the rear edge of the sludge container 5. The filtered supernatant liquid after moving in a close state passes through the filter element FE of, for example, a non-woven fabric (or mesh net, etc.) and flows to the outside of the filter drum D. The arrow “c” shown in FIG. In this direction, it is further sucked and collected by a suction means (not shown) in the direction of the arrow “d”.
[0047]
A second coil spring (fixed coil spring) 7 to which a first coil spring (rotating coil spring) 6 is fixed by a rotational drive of a conveying means U stored in the sludge container 5 and built in the bottom, and a rod-like shape free of both ends. The sludge is led to the outlet 13 by rotating and sliding while rubbing the surface of the core material 8 forming the body.
[0048]
On the other hand, the sludge led to the outlet 13 by the action of the conveying means U is provided around the drive shaft 10 connected to the drive source 11, and is stretched around the drive side sprocket 15 and the driven side sprocket 15 'to rotate and move. 4 is held by a sludge holding plate 16 attached to the chain 20 at a predetermined pitch and in a cantilevered manner via a spring member 16a in a cantilevered state, as shown in FIG. Then, it is pressed against the spring side wall of the casing 17 against the spring member 16a, moved while sliding, released from the pressed state at the position 19a immediately before the discharge port 19, and the reaction force of the spring member 16a. Thus, the sludge holding plate-like body 16 performs the turning operation, and at the same time, the sludge held on the sludge holding plate-like body 16 is scraped off by the scraping member 18 for scraping off the sludge. It is discharged from the outlet 19.
[0049]
Further explanation will be made. Although the free tip of the rotary coil spring 6 generates the maximum deflection near the root of the fixed fixed coil spring 7, it is revolved by the core material 8 which forms a rod-like body fitted inside the coil. The deviation of the trajectory can be suppressed.
[0050]
The tip of the wire rod of the rotating coil spring 6 formed into a conical shape climbs onto the fixed coil spring 7 to facilitate rotation and submersion rotation, and revolves around the fixed coil spring 7.
[0051]
The rotating coil spring 6 is revolved by a core material 8 that forms a rod-like body fitted inside the coil, although the free tip of the fixed coil spring 7 generates the maximum deflection near the root fixed to the drive shaft 10. The deviation of the trajectory can be suppressed.
[0052]
The tip of the fixed coil spring 7 formed into a conical shape makes it easy to climb and sink, and revolves around the rotating coil spring 6 so that the inner periphery of the rotating coil spring 6 and the outer periphery of the fixed coil spring 7 come into contact with each other. Of the rotating coil spring 6 and the inner periphery of the fixed coil spring 7 are in contact with the outer periphery of the core material 8 forming a rod-shaped body. Sludge and slurry adhering to the periphery and the periphery of the core material 8 can be fed in the discharge direction while mixing.
[0053]
And the discharge port currently provided in the end surface wall of the housing | casing 1 with the external suction pump (not shown) 14 The clear liquid that has passed through the mesh is discharged to an external liquid storage tank (not shown), and the clear liquid injection from the outer peripheral surface of the filter drum D through the cleaning nozzle hole 3a is sent from the external liquid storage tank to the liquid feed pump ( (Not shown).
[0054]
