【発明の属する技術分野】
本発明は、洗浄作用の良好な原液洗剤や液体に粉粒体を混入した液体メディア等の液状洗浄材を注入して形成した混合流を洗浄ノズルから噴射して洗浄作用を行う洗浄装置に関する。より詳しくは、運転の停止中の供給経路内に残留する沈殿したり固まりやすい原液洗剤や液体メディアあるいは粉粒体によって誘引される詰りを防止するための改良技術に関する。
【0002】
【従来の技術】
及び図は、従来の洗浄装置における要部を概略的に示した回路構成図である。図に示した従来技術においては、洗浄ノズル1に対して、エア供給管2からの加圧エアと、液体タンク3からの水等の適宜の液体に液状洗浄材タンク4からの洗浄作用の良好な液状洗浄材を注入した混合液体とが供給され、それらの加圧エアと混合液体とを混合して噴射することにより洗浄作用を行うように構成されている。なお、液状洗浄材としては、原液洗剤や粉粒体を混入してなる液体メディア等の洗浄作用の良好なものが使用される。図示のように、エア供給管2はエア供給源5に接続され、また液体タンク3はボールタップ等の液面調整手段6を介して水道等の液体供給源7に接続されている。また、液体タンク3には、必要に応じて逆止弁機能を備えた吸込口8を沈設した液体供給管9が接続されており、高圧ポンプ10を挟んで高圧供給管11を介して前記洗浄ノズル1に接続されている。さらに、高圧ポンプ10の上流側の液体供給管9には、液状洗浄材供給管12を介して前記液状洗浄材タンク4が接続されており、その途中に配設された前記高圧ポンプ10に比べて小容量低圧の注入用ポンプ13によって液状洗浄材が液体供給管9内に注入されるように構成されている。
【0003】
しかして、洗浄作業においては、注入用ポンプ13を駆動して液状洗浄材タンク4から原液洗剤や液体メディア等の洗浄作用の良好な液状洗浄材を液体供給管9内へ注入して管内の液体に混入させるとともに、高圧ポンプ10を介して所定圧に昇圧し、それらの混合液体を高圧供給管11を経て前記洗浄ノズル1へ供給することになる。この場合、前記注入用ポンプ13の流量は、高圧ポンプ10の流量より小さく設定して、高圧ポンプ10の下流側が加圧されて逆流することのないように構成されている。前記洗浄ノズル1においては、高圧供給管11を経て供給される液体と液状洗浄材との混合液体と、エア供給管2からの加圧エアとを混合しながら高速混合流として外部へ噴射することになる。その場合、図示しない洗浄ノズル1に付随する適宜のバルブ機構や注入用ポンプ13の容量制御等により混合比を調整することも可能である。なお、前記注入用ポンプ13を省略して高圧ポンプ10の吸込側の負圧によって液状洗浄材タンク4から液状洗浄材を吸引するように構成したり、図に示したように、前記液状洗浄材供給管12を高圧ポンプ10の下流側の高圧供給管11に接続するように構成することも可能である。これらの場合には高圧ポンプ10の下流側の液体供給管9が加圧されて吸込口8側へ逆流する恐れはないが、後者のように高圧供給管11に注入する場合には注入用ポンプ13の吐出圧を高圧に設定する必要がある。
【0004】
ところで、以上の従来の洗浄装置において洗浄作業が終了して高圧ポンプ10や注入用ポンプ13を停止した場合には、それらの高圧ポンプ10、注入用ポンプ13や、液状洗浄材供給管12、液体供給管9の連結部より下流側、高圧供給管11及び洗浄ノズル1内には、前述の原液洗剤や液体メディア等からなる液状洗浄材が残留することになる。そして、その液状洗浄材は沈殿しやすかったり固まりやすい場合が多いことから、洗浄運転の停止中にそれらの供給経路に詰りが生じやすく、以後の円滑な洗浄作業を阻害する原因にもなっていた。
【0005】
【発明が解決しようとする課題】
本発明は、以上の従来技術の問題点を解決するために開発したもので、簡単な構成により、従来のように洗浄運転の停止中に残留する原液洗剤や液体メディア等からなる液状洗浄材や粉粒体によって誘引される供給経路の詰りの恐れがない洗浄装置を提供することを目的とするものである。
【0006】
【課題を解決するための手段】
前記課題を解決するため、発明では、少なくとも液体に原液洗剤や液体メディア等の液状洗浄材を注入してなる混合流を洗浄ノズルから噴射して洗浄作用を行う洗浄装置において、前記液体を貯留する液体タンクと、前記液状洗浄材を貯留する液状洗浄材タンクと、前記液体タンク内の液体を洗浄ノズルへ供給する液体供給管と、前記液状洗浄材タンクと前記液体供給管とを接続して液状洗浄材タンク内の液状洗浄材を前記液体供給管に供給する液状洗浄材供給管とを設け、さらに前記液状洗浄材タンク近傍の液状洗浄材供給管と管路内清浄用の洗浄水を貯留した洗浄水貯留部とを管路用洗浄水供給管にて連結するとともに、その液状洗浄材供給管と管路用洗浄水供給管との連結部分に液状洗浄材又は管路用洗浄水のいずれか一方を流通可能な状態に切換える切換手段を配設し、液状洗浄材使用後、該切換手段を切換えて前記液状洗浄材供給管に洗浄水を流すという技術手段を採用した
【0007】
【発明の実施の形態】
発明の実施形態としては、主に洗浄作用を受持つ前記液状洗浄材として、化学的な洗浄作用を有する原液洗剤や物理的な洗浄作用を有する液体メディア等の洗浄作用の良好なものが用いられる。また、その液状洗浄材を適度に薄めたり搬送する流体としては、液体のみの形態や液体と気体の双方を使用する形態が可能である。洗浄ノズルとしては、それらの供給される液状洗浄材や搬送流体を内部で混合しながら噴射可能な従来から知られている適宜の形態の噴射ノズルの使用が可能である。なお、洗浄水や液状洗浄材の供給回路構成としては、前述の図及び図に示したようにポンプを用いた形態だけでなく、後述の図3や図4に示すように、液状洗浄材注入用のポンプを省略して洗浄液供給用のポンプの吸込側負圧を利用して供給するように構成したり、双方のポンプを省略して洗浄ノズル内における加圧エア流のエジェクタ作用を利用して供給するように構成することも可能である。また、各回路構成で採用される液体供給用ポンプないし液状洗浄材注入用ポンプの具体的な形式や吐出流量及び吐出圧などの容量に関しては、その回路構成の形態や規模の大きさ等を勘案して適宜決定される。さらに、それらの供給回路を切換えるための前記切換手段としては、一組の三方弁を用いる形態や、二組の開閉弁を用いる形態などが可能である。
【0008】
【実施例】
以下、図面を用いて本発明の実施例に関して説明する。図1は本発明の第1実施例の要部を概略的に示した回路構成図である。図示のように、本実施例は、前述の図に示した従来技術の洗浄装置と同様の洗浄機構を有しており、さらにその液状洗浄材供給管12の液状洗浄材タンク4の近傍に切換手段として三方弁等からなる切換弁14を配設して、該切換弁14と液体タンク3との間を管路用洗浄水供給管15を介して接続することにより、通常の洗浄運転停止中の前記供給経路内に残留する液状洗浄材を外部へ流出して除去する自己管路内清浄回路を構成した点で特徴を有する。すなわち、本実施例は、液体タンク3に供給される水道水等を洗浄水として活用する場合を例示したもので、洗浄作業が終了した場合には、切換弁14を切換えて液状洗浄材タンク4側への通路を遮断し、液状洗浄材供給管12に管路用洗浄水供給管15を連通させて、液体タンク3内の水を洗浄水として洗浄作業時と同様の供給経路を通じて洗浄ノズル1から噴射することにより自己管路内清浄作業を実施するように構成したものである。この自己管路内清浄作業時には、高圧ポンプ10及び注入用ポンプ13も駆動され、供給経路すなわち切換弁14、液状洗浄材供給管12、注入用ポンプ13、液体供給管9、高圧ポンプ10、高圧供給管11ないし洗浄ノズル1内に残留する液状洗浄材は外部へ流出されることから、従来のように運転停止中に残留する液状洗浄材によってそれらの経路内が詰る問題は解消される。
【0009】
なお、前記洗浄水に関しては、液体タンク3とは別に専用の洗浄水タンクを設置し、そのタンクに貯留された洗浄水を使用するように構成し得ることはいうまでもない。すなわち、管路内清浄用の洗浄水を貯留する洗浄水貯留部の形態としては、前記実施例で例示したように通常の洗浄作業に使用される液体タンク3を兼用した形態でも、液体タンク3とは別に設置した専用の洗浄水タンクを用いる形態でもよい。また、前記自己管路内清浄作業によっては、切換弁14と液状洗浄材タンク4との間に残留する液状洗浄材は除去できないので、それらの切換弁14と液状洗浄材タンク4との間隔はできる限り小さく設定することが望ましい。さらに、液状洗浄材供給管12の液体供給管9への接続部の近傍にバネ付の逆止弁を設けて逆流を防ぐようにしてもよい。
【0010】
図2は本発明の第2実施例の要部を概略的に示した回路構成図である。図示のように、本実施例は、前述の図に示した従来技術に対応したものであり、同従来技術と同様に、液状洗浄材供給管12を高圧ポンプ10の下流側の高圧供給管11に接続するように構成したものである。他の自己管路内清浄機構等に関しては、前記第1実施例と同様であり、液状洗浄材供給管12の液状洗浄材タンク4のなるべく近傍に切換弁14を配設して、該切換弁14と液体タンク3との間を管路用洗浄水供給管15を介して接続することにより、洗浄運転停止中の前記供給経路内に残留する液状洗浄材を流出する自己管路内清浄回路を構成し、同様の自己清浄作用を奏するものである。
【0011】
図3は本発明の第3実施例の要部を概略的に示した回路構成図である。本実施例は、前記第1実施例において液状洗浄材供給管12の途中に配設された注入用ポンプ13を省略して高圧ポンプ10の吸込側の負圧によって液状洗浄材タンク4から液状洗浄材を吸引するように構成したものである。本実施例における洗浄作業終了後の自己管路内清浄機構も、前記第1実施例と同様であり、液状洗浄材供給管12の液状洗浄材タンク4のなるべく近傍に切換弁14を配設して、該切換弁14と液体タンク3との間を管路用洗浄水供給管15を介して接続することにより、洗浄運転停止中の前記供給経路内に残留する液状洗浄材を流出する自己管路内清浄回路を構成し、同様の自己清浄作用を奏するものである。なお、液状洗浄材供給管12の途中にバルブ機構16を配設して、液状洗浄材の供給量の調整や開閉を制御し得るように構成することも可能である。
【0012】
図4は本発明の第4実施例の要部を概略的に示した回路構成図である。本実施例は、前記第3実施例における高圧ポンプ10を更に省略して代りにバルブ機構17を配設し、前記洗浄ノズル1内における加圧エア流のエジェクタ作用を利用して液体タンク3内の液体及び液状洗浄材タンク4内の液状洗浄材の双方を吸引するように構成したものである。なお、バルブ機構16及び17の配置関係に関しては、図示のようにバルブ機構16の下流側をバルブ機構17の上流側に接続してもよいし、逆にバルブ機構17の下流側に接続するように変更してもよい。本実施例における洗浄作業終了後の自己管路内清浄機構は、以上の実施例と同様であり、同様の自己管路内清浄作用を奏するものである。
【0013】
図5は本発明の第5実施例の要部を概略的に示した回路構成図である。本実施例は、前記第1実施例の変形例で、切換手段として採用された三方弁等からなる前記切換弁14に代えて、二組の開閉弁18,19により切換手段を構成したものである。その他の回路構成は第1実施例と同じで、同様の洗浄作用及び自己管路内清浄作用を奏するものである。なお、本実施例では、第1実施例の変形例として説明したが、他の第2実施例ないし第4実施例における切換弁14に代えて二組の開閉弁18,19からなる切換手段を採用することにより、同様にそれぞれの変形例が可能である。
【0014】
【発明の効果】
本発明によれば、以上のようにきわめて簡単な構成により、洗浄運転の停止中の供給経路内に原液洗剤や液体メディア等からなる液状洗浄材や粉粒体が残留することは回避されるので、従来それらの液状洗浄材や粉粒体によって誘引された詰りの問題は解消され、その後の円滑な洗浄運転が可能となり、継続的かつ良好な洗浄作業が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a cleaning device for cleaning action injected from the washing nozzle entrained liquid media such as mixed stream to form a liquid cleaning material is injected in a good stock detergents or liquids granule of washing action . More particularly, to an improved technique for preventing clogging Thus it is attracted to precipitate or solidify easily undiluted detergent or liquid media or granular material remaining in the supply path during stop of the operation.
[0002]
[Prior art]
6 and 7 are circuit configuration diagrams schematically showing a main part of a conventional cleaning apparatus. In the prior art shown in FIG. 6 , the cleaning action from the liquid cleaning material tank 4 is applied to the cleaning nozzle 1 with an appropriate liquid such as pressurized air from the air supply pipe 2 and water from the liquid tank 3. A mixed liquid into which a good liquid cleaning material is injected is supplied, and the compressed air and the mixed liquid are mixed and injected to perform a cleaning action. In addition, as the liquid cleaning material, a material having a good cleaning action such as a liquid medium mixed with a stock detergent or a granular material is used. As shown in the figure, the air supply pipe 2 is connected to an air supply source 5, and the liquid tank 3 is connected to a liquid supply source 7 such as tap water via liquid level adjusting means 6 such as a ball tap. The liquid tank 3 is connected to a liquid supply pipe 9 having a suction port 8 provided with a check valve function as necessary. The liquid tank 3 is connected to the liquid tank 3 via the high-pressure supply pipe 11 with the high-pressure pump 10 interposed therebetween. Connected to the nozzle 1. Further, the liquid cleaning material tank 4 is connected to the liquid supply pipe 9 on the upstream side of the high-pressure pump 10 via a liquid cleaning material supply pipe 12, compared with the high-pressure pump 10 disposed in the middle thereof. Thus, the liquid cleaning material is injected into the liquid supply pipe 9 by a small-capacity low-pressure injection pump 13.
[0003]
Thus, in the cleaning operation, the injection pump 13 is driven to inject a liquid cleaning material having a good cleaning action, such as a stock detergent or a liquid medium, from the liquid cleaning material tank 4 into the liquid supply pipe 9 and the liquid in the pipe. In addition, the pressure is increased to a predetermined pressure via the high-pressure pump 10, and the mixed liquid is supplied to the cleaning nozzle 1 through the high-pressure supply pipe 11. In this case, the flow rate of the injection pump 13 is set smaller than the flow rate of the high-pressure pump 10 so that the downstream side of the high-pressure pump 10 is pressurized and does not flow backward. In the cleaning nozzle 1, the mixed liquid of the liquid and the liquid cleaning material supplied via the high-pressure supply pipe 11 and the pressurized air from the air supply pipe 2 are mixed and injected outside as a high-speed mixed flow. become. In that case, it is also possible to adjust the mixing ratio by an appropriate valve mechanism associated with the cleaning nozzle 1 (not shown), volume control of the injection pump 13, or the like. Incidentally, the infusion pump 13 is omitted or configured to suck the liquid cleaning material from the liquid cleaning material tank 4 by the negative pressure of the suction side of the high pressure pump 10, as shown in FIG. 7, the liquid cleaning It is possible to connect the material supply pipe 12 to the high-pressure supply pipe 11 on the downstream side of the high-pressure pump 10. In these cases, there is no fear that the liquid supply pipe 9 on the downstream side of the high-pressure pump 10 is pressurized and flows back to the suction port 8 side. It is necessary to set the discharge pressure of 13 to a high pressure.
[0004]
By the way, when the high pressure pump 10 and the injection pump 13 are stopped in the above conventional cleaning apparatus and the high pressure pump 10 and the injection pump 13 are stopped, the high pressure pump 10, the injection pump 13, the liquid cleaning material supply pipe 12, the liquid In the high-pressure supply pipe 11 and the cleaning nozzle 1 on the downstream side of the connecting portion of the supply pipe 9, the liquid cleaning material composed of the above-described undiluted detergent or liquid medium remains. And since the liquid cleaning material tends to settle or harden in many cases, the supply path is easily clogged during the stoppage of the cleaning operation, which has also hindered the subsequent smooth cleaning operation. .
[0005]
[Problems to be solved by the invention]
The present invention was developed to solve the above-described problems of the prior art, and with a simple configuration, a liquid cleaning material comprising a stock detergent or a liquid medium remaining during a stoppage of the cleaning operation as in the prior art, It is an object of the present invention to provide a cleaning device that is free from clogging of a supply path that is attracted by powder particles.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in the present invention, the liquid is stored in a cleaning device that performs a cleaning action by injecting a mixed flow obtained by injecting at least a liquid cleaning material such as a stock detergent or a liquid medium into a liquid from a cleaning nozzle. A liquid tank that stores the liquid cleaning material, a liquid supply pipe that supplies the liquid in the liquid tank to a cleaning nozzle, and the liquid cleaning material tank and the liquid supply pipe are connected to each other. A liquid cleaning material supply pipe for supplying the liquid cleaning material in the liquid cleaning material tank to the liquid supply pipe is provided, and further, a liquid cleaning material supply pipe in the vicinity of the liquid cleaning material tank and cleaning water for cleaning in the pipeline are stored. with a the wash water reservoir connecting with the duct cleaning water supply pipe, one of the liquid cleaning material or the duct washing water to the connecting portion between the liquid cleaning material supply pipe and the duct cleaning water supply pipe Either one can be distributed Disposed a switching means for switching to a state after use liquid cleaning material, employing the technical means of flowing cleaning water in the liquid cleaning material supply pipe by switching said changeover switching means.
[0007]

It is done. In addition, as a fluid for thinning or transporting the liquid cleaning material, a liquid only form or a form using both liquid and gas is possible. As the cleaning nozzle, it is possible to use an injection nozzle of an appropriate form known from the past that can be jetted while mixing the supplied liquid cleaning material and carrier fluid inside.
