Description

本発明は、高圧水による洗浄装置のスプレーガンを備えた洗浄ハウジングと、エジェクタを備えた洗浄水回収ハウジングとを取り付け、洗浄ハウジングの洗浄水を回収ハウジング内に通し、回収ハウジング内のエジェクタで回収した洗浄水をバグフィルターで濾過し廃出するジェット洗浄及び洗浄水回収装置に関するものである。   The present invention includes a cleaning housing having a spray gun for a high-pressure water cleaning device and a cleaning water recovery housing having an ejector, passing cleaning water from the cleaning housing through the recovery housing, and recovering with the ejector in the recovery housing. The present invention relates to a jet cleaning and cleaning water recovery device for filtering out the cleaning water with a bag filter and discharging it.

従来、研磨材を高圧水と混合して噴射する高圧水ジェット利用加工装置において、ジェット流のエジェクタ効果を利用して、研磨材と高圧水を吸引し、分離器により研磨材を回収するウォータジェット加工装置の廃液処理装置はしられている(特許文献1参照。)。   Conventionally, in a high-pressure water jet processing device that jets abrasives mixed with high-pressure water and jets, a water jet that uses the ejector effect of the jet stream to suck the abrasives and high-pressure water and collect the abrasives using a separator The waste liquid processing apparatus of the processing apparatus is used (refer patent document 1).

又、ウォータジェット加工装置のノズルからの研磨材混合廃液を受けるキャッチタンクと、研磨材を沈降分離させる沈降タンクとを有し、キャッチタンクから沈降タンクに連通する水管路に圧力流体を噴射することでキャッチタンクから沈降タンクへ移送する流れを発生させる移送用エジェクタ手段を備え研磨材回収装置(特許文献2参照。)もしられている。   Also, a catch tank that receives the abrasive mixed waste liquid from the nozzle of the water jet machining apparatus and a sedimentation tank that settles and separates the abrasive is injected, and a pressure fluid is injected from the catch tank to a water conduit that communicates with the sedimentation tank. In addition, an abrasive recovery device (see Patent Document 2) is also provided that includes a transfer ejector means for generating a flow to be transferred from the catch tank to the sedimentation tank.

これら技術は、研磨材の回収のためにエジェクタを利用するものである。   These techniques use an ejector to recover the abrasive.

このような従来型の高圧水を用いた洗浄装置では、ジェット洗浄時に多量のミストが発生し視界を悪化させたり、RI施設等ではダスト発生を増幅し作業環境を低下させること、そして高圧水を用いて洗浄しても底部は水はけが悪いので、汚れた残水で再び汚染させてしまうこと等の問題があった。   In such a conventional cleaning device using high-pressure water, a large amount of mist is generated during jet cleaning, deteriorating the field of view, and in RI facilities, etc., dust generation is amplified to lower the working environment, and high-pressure water is used. Even if it is used and washed, there is a problem in that the bottom part is poorly drained, so that it is contaminated again with dirty residual water.

このため、事前に底部に溜まった残水を回収し、次にジェット洗浄を行う。再び、ジェット洗浄で噴射した洗浄水を回収する必要があった。   For this reason, the residual water collected in the bottom part is collect | recovered beforehand, and jet cleaning is performed next. Again, it was necessary to collect the washing water sprayed by jet washing.

さらに、従来の残水回収でポンプを用いると、残水中に異物(固形物)があるとポンプを閉塞させたり、エンペラー等に損傷を与えた。   Further, when a pump is used in the conventional residual water recovery, if the foreign water (solid matter) is present in the residual water, the pump is blocked or the emperor is damaged.

さらに又、通常のポンプでは、水位が低くなると、空気を吸引し、残水まで吸引することができなかった。

Jet cleaning and cleaning water recovery device,
The jet cleaning and cleaning water recovery apparatus includes a cleaning housing having a high pressure spray nozzle for high pressure water sent from a high pressure cleaning machine, and an ejector mechanism for recovering and discharging the cleaning water cleaned in the cleaning housing. Is a structure that combines
The cleaning housing and the cleaning water recovery housing communicate with each other at the bottom,
The high-pressure water to the cleaning housing and the high-pressure water to the cleaning water recovery housing can be switched and used via a switching valve,
Waste water generated during jet cleaning in the cleaning housing and mist are sucked and discharged by the ejector mechanism in the cleaning water recovery housing.
The cleaning housing has a divergent shape toward the surface to be cleaned, has a spray nozzle at the top of the cleaning housing, and the cleaning water recovery housing has an ejector mechanism at the top. The high-pressure water piping to the outlet and the discharge hose from the ejector device in the washing water recovery housing are arranged in parallel to facilitate switching of the high-pressure water to both housings by the switching valve.
And the filter housing was provided in the terminal of the drainage hose.

従来のジェット洗浄では、ジェット水によりミストを発生し、放射性ダストを巻き上げたが、洗浄ハウジングと洗浄水回収ハウジングを組合せ、洗浄ハウジング内で巻き上げたミスト等を吸引回収するので、良好な作業環境を維持できる。   In conventional jet cleaning, mist was generated by jet water and radioactive dust was wound up, but the cleaning housing and the cleaning water recovery housing were combined to collect and suck up the mist that was lifted up in the cleaning housing. Can be maintained.

又、洗浄水回収ハウジング内でのエジェクタ機構により水中でのスラッジ回収の他、床面に溜まった残水を完全に吸引回収できる。   Moreover, the ejector mechanism in the washing water collecting housing can completely collect and collect the residual water accumulated on the floor surface in addition to collecting sludge in water.

さらに従来は、重装備(PVCスーツ、全面マスク着用)による人手によるジェット洗浄作業と残水回収をしいられたが、本発明により、洗浄と回収作業をも同時にでき、作業員の負担を軽減できるようになった。   Furthermore, in the past, manual cleaning with heavy equipment (PVC suit, full-face mask wearing) and residual water recovery were performed. However, according to the present invention, cleaning and recovery can be performed at the same time, reducing the burden on workers. It became so.

又、ピット等の異物や汚泥が堆積した水も真空で吸引するので回収することが容易にできる。   Moreover, since foreign matter such as pits and water on which sludge is accumulated are sucked in vacuum, they can be easily recovered.

図1は、水抜後のプール、ピットあるいはタンクの底部に付着した汚れを除去・回収する装置の概略系統図である。洗浄水は高圧ポンプ1で高圧水となって分岐管2で分岐され、一方は高圧スプレーノズル3への流水と、高圧洗浄水の切替弁4を経てエジェクタノズル5への流れに分岐される。高圧スプレーノズル3は、汚れた洗浄ハウジング6の底部を洗浄すべく底部で連通している洗浄ハウジング6内へ高圧水を吐出す。   FIG. 1 is a schematic system diagram of an apparatus for removing and collecting dirt adhered to the bottom of a pool, pit or tank after draining. The washing water becomes high-pressure water by the high-pressure pump 1 and is branched by the branch pipe 2. One of the washing water is branched into a flow to the high-pressure spray nozzle 3 and a flow to the ejector nozzle 5 through the high-pressure washing water switching valve 4. The high-pressure spray nozzle 3 discharges high-pressure water into the cleaning housing 6 communicating with the bottom to clean the bottom of the dirty cleaning housing 6.

洗浄水回収ハウジング8内では、エジェクタノズル5から噴出した水は、エジェクタ機構7内通って排水ホース9に高圧水と回収ハウジング8で回収した水と共に送られ、バグフィルターハウジング10に送られ、ここでバグフィルター11で濾過される。   In the washing water recovery housing 8, the water ejected from the ejector nozzle 5 passes through the ejector mechanism 7, is sent to the drain hose 9 together with the high pressure water and the water recovered by the recovery housing 8, and is sent to the bag filter housing 10. And filtered by the bag filter 11.

エジェクタ機構7は、図3に示すように、高圧水をエジェクタ機構7に噴出することにより洗浄水回収ハウジング8を負圧にし、高圧洗浄で発生したミストや洗浄後の排水や底部に残っていた残水を吸引し、エジェクタ5から吐出された水をエジェクタ源として噴射された水で圧送され移送される。   As shown in FIG. 3, the ejector mechanism 7 makes the washing water recovery housing 8 have a negative pressure by ejecting high-pressure water to the ejector mechanism 7, and remains in the mist generated by the high-pressure washing, the waste water after washing, or the bottom. Residual water is sucked, and the water discharged from the ejector 5 is pumped and transferred by the jetted water using the ejector source.

高圧水と同時に回収された汚水は、排水ホース9を経由してバグフィルター11等のフィルタで濾過回収する。   The sewage collected at the same time as the high-pressure water is filtered and collected by a filter such as a bag filter 11 via the drainage hose 9.

エジェクタ部の構成を図3でより詳細に示す。
ジェット洗浄・回収器は、高圧洗浄器12から供給された高圧水をランス13で開閉し、洗浄ノズル3から吐出し洗浄水回収ハウジング8内で底部を洗浄する。また、高圧水はエジェクタ吐出用として、切替弁4を経てエジェクタノズル5からエジェクタ7に向かい高圧で吐出される、このとき、洗浄水回収ハウジング8内は、エジェクタ効果により真空となり、ジェット洗浄後の水やジェット洗浄で発生したミストを吸引するのと共に、底部に溜まった残水をも吸引し、排水ホース9に送る。
The configuration of the ejector portion is shown in more detail in FIG.
The jet cleaning / recovering device opens and closes the high-pressure water supplied from the high-pressure cleaning device 12 with the lance 13, discharges it from the cleaning nozzle 3, and cleans the bottom in the cleaning water recovery housing 8. Moreover, high pressure water is discharged at high pressure from the ejector nozzle 5 to the ejector 7 through the switching valve 4 for ejecting the ejector. At this time, the inside of the cleaning water recovery housing 8 is evacuated by the ejector effect, and after jet cleaning is performed. In addition to sucking water and mist generated by jet cleaning, the remaining water collected at the bottom is also sucked and sent to the drain hose 9.

エジェクタ機構7は、エジェクタ内径を変えることにより大流量・低揚程型と低流量・高揚程型等に変更することができる。   The ejector mechanism 7 can be changed to a large flow rate / low head type and a low flow rate / high head type by changing the inner diameter of the ejector.

回収された残水やジェット洗浄水は、付属のフィルタ11で濾過回収できる。
なお、図2は、回収専用器で、高圧洗浄機構12は省き、高圧水を全て、エジェクタに供給することにより、回収性能を向上させたものである。
