Description

本発明は、圧縮空気と液体とを混合して噴霧する噴霧装置に関する。 The present invention relates to a spraying device that mixes and sprays compressed air and a liquid.

図２は圧縮空気と水とを混合して噴霧する水噴霧装置の構成を示す図であって、この水噴霧装置は例えば、靴等に付着した泥を除去することに用いられる。前記水噴霧装置は空気圧縮機１と空気槽５と貯水槽１５と噴霧ノズル１０とを備え、前記空気圧縮機１が吐出した圧縮空気を一旦空気槽５で貯留してから該圧縮空気を噴霧ノズル１０に供給し、前記噴霧ノズル１０は混合部１１内の空気通路を圧縮空気が流通することで貯水槽１５内の水を該混合部１１内に吸い上げ、圧縮空気と水とを混合して大気へ噴霧する。 FIG. 2 is a diagram showing a configuration of a water spraying device that mixes and sprays compressed air and water, and this water spraying device is used for removing mud adhering to shoes or the like, for example. The water spray device includes an air compressor 1, an air tank 5, a water storage tank 15, and a spray nozzle 10. The compressed air discharged from the air compressor 1 is temporarily stored in the air tank 5 and then sprayed with the compressed air. The spray nozzle 10 sucks the water in the water storage tank 15 into the mixing unit 11 by the compressed air flowing through the air passage in the mixing unit 11 and mixes the compressed air and water. Spray to atmosphere.

前記空気圧縮機１はモータ４によって駆動されることにより外気を吸入して圧縮し、圧縮空気は空気槽５内に吐出される。前記空気槽５に貯留される圧縮空気は温度低下により該空気中の水分が凝縮して空気槽５の底部にドレンが溜まる。このように空気槽５の底部に溜まったドレンは定期的に排出する必要があり、例えば空気圧縮機１の運転を停止したときに作業者が空気槽５の底部と連通するドレン配管２４に設けたドレンコック２５を開いてドレンを機外に排出したり、前記ドレン配管２４にドレン自動排出装置を設け、ドレンが所定量溜まったときに自動で排出弁を開いてドレンを機外へ排出していた（特許文献１参照）。 The air compressor 1 is driven by a motor 4 to suck and compress outside air, and the compressed air is discharged into an air tank 5. The compressed air stored in the air tank 5 condenses moisture in the air due to a decrease in temperature and accumulates drainage at the bottom of the air tank 5. Thus, the drain accumulated at the bottom of the air tank 5 needs to be discharged periodically. For example, when the operation of the air compressor 1 is stopped, the operator is provided in the drain pipe 24 that communicates with the bottom of the air tank 5. The drain cock 25 is opened to discharge the drain to the outside of the machine, or the drain pipe 24 is provided with an automatic drain discharge device, and when the drain has accumulated a predetermined amount, the drain valve is automatically opened and the drain is discharged to the outside of the machine. (See Patent Document 1).

しかしながら、作業者はドレンコック２５を開いてドレンを機外に排出するドレンの排出作業を煩わしく思っていて確実に行われないことから、空気槽５内に長期間ドレンが貯留されてしまう。また、ドレン配管２５にドレン自動排出装置を設けた場合には、作業者によるドレンの排出作業が不要となることから確実にドレンの排出が行われるが、ドレン自動排出装置は高価である。 However, since the operator is troublesome to open the drain cock 25 and discharges the drain to the outside of the machine and is not surely performed, the drain is stored in the air tank 5 for a long time. Moreover, when the drain automatic discharge device is provided in the drain pipe 25, the drain discharge is surely performed because the drain discharge operation by the operator is unnecessary, but the drain automatic discharge device is expensive.

このことから、本発明は噴霧装置において、作業者によるドレン排出作業を不要とすると共に、高価なドレン自動排出装置を用いずに、空気槽内で発生したドレンを簡便に排出することを目的とする。 Therefore, the present invention aims to eliminate drain work by an operator in a spray device and to easily drain drain generated in an air tank without using an expensive automatic drain device. To do.

上記目的を達成するために、本発明の噴霧装置は、圧縮空気を吐出する空気圧縮機１と、圧縮空気を貯留する空気槽５と、液体を貯留する液体槽１５と、圧縮空気と液体とを混合して噴霧する噴霧ノズル１０とを備え、前記噴霧ノズル１０に前記空気槽５の底部に連通する配管８，１６と液体槽１５に連通する配管１７とを接続し、圧縮空気と共に空気槽５に溜まったドレンを液体と混合して噴霧することを特徴とする。 In order to achieve the above object, the spray device of the present invention includes an air compressor 1 that discharges compressed air, an air tank 5 that stores compressed air, a liquid tank 15 that stores liquid, and compressed air and liquid. A spray nozzle 10 for mixing and spraying, and connecting the spray nozzle 10 with pipes 8 and 16 communicating with the bottom of the air tank 5 and a pipe 17 communicating with the liquid tank 15 together with compressed air. The drain collected in 5 is mixed with a liquid and sprayed.

本発明の噴霧装置は、噴霧ノズル１０に空気槽５の底部に連通する配管８，１６と液体槽１５に連通する配管１７とを接続し、圧縮空気と共に空気槽５に溜まったドレンを液体と混合して噴霧することから、作業者によるドレン排出作業を不要とすると共に、高価なドレン自動排出装置を用いずに、空気槽５内で発生したドレンを簡便に排出することができ、空気槽５内に長期間ドレンが貯留されることがない。また、空気槽５の上部と連通する配管７，２２から供給される圧縮空気にはドレンを含んでいないことから、従来と同様にドレンの含有を嫌う一般的な空気機器に圧縮空気を供給することが可能である。 The spraying apparatus of the present invention connects the pipes 8 and 16 communicating with the bottom of the air tank 5 to the spray nozzle 10 and the pipe 17 communicating with the liquid tank 15, and drains accumulated in the air tank 5 together with the compressed air as liquid. Since it is mixed and sprayed, drain discharge work by an operator is unnecessary, and drain generated in the air tank 5 can be easily discharged without using an expensive automatic drain discharge device. No drain is stored for a long time in 5. In addition, since the compressed air supplied from the pipes 7 and 22 communicating with the upper part of the air tank 5 does not contain drainage, the compressed air is supplied to general air equipment that dislikes the drainage as in the conventional case. It is possible.

次に、本発明の実施形態について添付図面を参照しながら以下説明する。 Next, embodiments of the present invention will be described below with reference to the accompanying drawings.

〔実施形態１〕
図１は、本発明の水噴霧装置を示す図である。 Embodiment 1
FIG. 1 is a view showing a water spray device of the present invention.

水噴霧装置は、圧縮空気を吐出する空気圧縮機１と、圧縮空気を貯留する空気槽５と、液体である水を貯留する貯水槽１５と、圧縮空気と水とを混合して噴霧する噴霧ノズル１０及び圧縮空気を噴出する空気ノズル２０とを備え、水噴霧装置の筐体２内に、前記空気圧縮機１と、前記空気圧縮機１を駆動するモータ４と、前記空気槽５とを収容している。 The water spraying apparatus is a spray that mixes and sprays compressed air and water, an air compressor 1 that discharges compressed air, an air tank 5 that stores compressed air, a water tank 15 that stores liquid water. A nozzle 10 and an air nozzle 20 for ejecting compressed air, and the air compressor 1, the motor 4 for driving the air compressor 1, and the air tank 5 in a housing 2 of a water spraying device. Contained.

前記空気槽５には第１の空気配管７と第２の空気配管８とが接続され、それぞれの配管の他端は機外へ延設し、前記第１の空気配管７は一端を空気槽５の上部と連通すると共に他端を柔軟性のある空気ホース２２を介して前記空気ノズル２０と連通し、前記第２の空気配管８は一端を空気槽５の底部と連通すると共に他端を柔軟性のある空気ホース１６を介して前記噴霧ノズル１０と連通している。 A first air pipe 7 and a second air pipe 8 are connected to the air tank 5, the other end of each pipe extends outside the apparatus, and the first air pipe 7 has one end at the air tank. 5 and the other end communicated with the air nozzle 20 via a flexible air hose 22. The second air pipe 8 communicates one end with the bottom of the air tank 5 and the other end. It communicates with the spray nozzle 10 via a flexible air hose 16.

前記噴霧ノズル１０には圧縮空気と水とを混合する混合部１１を備え、前記混合部１１には空気槽５の底部と連通する前記空気ホース１６と共に前記貯水槽１５に連通する水ホース１７を接続している。本実施形態の混合部１１には噴霧量を調整する引き金１２が設けられていて、この引き金１２を引くことにより前記混合部１１に内蔵する弁体を開き、混合部１１内の空気通路を圧縮空気が高速で流通することにより貯水槽１５内の水を該混合部１１へ吸い上げ、圧縮空気と水とを混合する。 The spray nozzle 10 includes a mixing unit 11 that mixes compressed air and water. The mixing unit 11 includes a water hose 17 that communicates with the water storage tank 15 together with the air hose 16 that communicates with the bottom of the air tank 5. Connected. The mixing portion 11 of this embodiment is provided with a trigger 12 for adjusting the spray amount. By pulling the trigger 12, the valve body built in the mixing portion 11 is opened, and the air passage in the mixing portion 11 is compressed. When the air flows at a high speed, the water in the water storage tank 15 is sucked into the mixing unit 11 and the compressed air and water are mixed.

なお、本実施形態は空気槽５を筐体２内に収納しているが、空気槽５を筐体２外に配置してもよい。また、本実施形態では貯水槽１５を筐体２外に配置しているが、貯水槽１５を筐体２内に収納してもよく、前記貯水槽１５内にフロート弁を設け、貯水槽１５内の水位が所定の水位まで下がると弁を開いて水道からの水を貯水槽１５内に給水し、貯水槽１５内の水位が所定の水位まで上がると弁を閉じて給水を止めるようにしてもよい。 In the present embodiment, the air tank 5 is housed in the housing 2, but the air tank 5 may be disposed outside the housing 2. Further, in this embodiment, the water tank 15 is disposed outside the housing 2, but the water tank 15 may be housed in the housing 2, and a float valve is provided in the water tank 15, so that the water tank 15 When the water level in the water tank drops to a predetermined water level, the valve is opened to supply water from the water supply into the water tank 15, and when the water level in the water tank 15 rises to the predetermined water level, the valve is closed to stop the water supply. Also good.

以上のように構成された水噴霧装置は、モータ４が空気圧縮機１を駆動することにより、外気を空気圧縮機１に吸入して圧縮し、圧縮空気は空気槽５内に吐出され一旦貯留される。空気槽内で圧縮空気が貯留されると、温度低下により該空気中の水分が凝縮して空気槽５の底部にドレンが溜まる。 In the water spray apparatus configured as described above, the motor 4 drives the air compressor 1 to suck and compress the outside air into the air compressor 1, and the compressed air is discharged into the air tank 5 and temporarily stored. Is done. When compressed air is stored in the air tank, moisture in the air is condensed due to a temperature drop, and drainage is collected at the bottom of the air tank 5.

前記噴霧ノズル１０の引き金１２を引くと前記混合部１１に内蔵する弁体が開き、この混合部１１内の空気通路を圧縮空気が流通する。そして、前記空気槽５内の底部に溜まったドレンは、圧縮空気の圧力と大気との圧力差によって空気槽５から前記第２の空気配管８及び前記空気ホース１６を介して前記混合部１１まで押し出される。前記混合部１１では空気通路を圧縮空気が高速で流通することによって前記水ホース１７を介して前記貯水槽１５内の水を吸い上げ、圧縮空気とドレンと水とを混合する。その後、噴霧パイプの先端から圧縮空気とドレンと水との混合流体を大気へ噴霧する。なお、空気槽５内で発生したドレンは空気中の水分が凝縮したものであるから、不純物の少ない蒸留水で、噴霧される水とほとんど変わらない。 When the trigger 12 of the spray nozzle 10 is pulled, a valve body built in the mixing unit 11 is opened, and compressed air flows through the air passage in the mixing unit 11. The drain accumulated in the bottom of the air tank 5 reaches the mixing section 11 from the air tank 5 through the second air pipe 8 and the air hose 16 due to the pressure difference between the pressure of compressed air and the atmosphere. Extruded. In the mixing unit 11, compressed air flows through the air passage at high speed to suck up the water in the water storage tank 15 through the water hose 17 and mix the compressed air, drain, and water. Thereafter, a mixed fluid of compressed air, drain, and water is sprayed to the atmosphere from the tip of the spray pipe. In addition, since the drain which generate | occur | produced in the air tank 5 is what condensed the water | moisture content in the air, it is almost the same as the water sprayed with distilled water with few impurities.

これにより、ドレンが圧縮空気及び水と共に噴霧ノズル１０から噴霧されるので、高価なドレン自動排出装置を用いることなく、作業者によるドレンの排出作業が不要となり、空気槽５内で発生したドレンを簡便に排出することができ、空気槽５内に長期間ドレンが貯留されることがなくなった。 Thereby, since the drain is sprayed from the spray nozzle 10 together with the compressed air and water, the drain discharge operation by the operator is unnecessary without using an expensive drain automatic discharge device, and the drain generated in the air tank 5 is removed. The air can be easily discharged, and the drain is not stored in the air tank 5 for a long time.

また、第１の空気配管７は空気槽５の上部と連通することから、空気ホース２２を介して空気ノズル２０へ供給される圧縮空気にはドレンを含まず、従来と同様にドレンの含有を嫌う一般的な空気機器に圧縮空気を供給することが可能である。 In addition, since the first air pipe 7 communicates with the upper part of the air tank 5, the compressed air supplied to the air nozzle 20 via the air hose 22 does not contain drain, but contains drain as in the conventional case. It is possible to supply compressed air to general air equipment that is disliked.

この水噴霧装置を例えば、靴等に付着した泥を除去することに用いるときには、噴霧ノズル１０の先端を泥が付着した箇所に向けて引き金１２を引き、圧縮空気とドレンと水との混合流体を噴霧し泥を洗い流す。その後空気ノズル２０の先端を靴に向けて引き金２１を引き、ドレンの含まない圧縮空気で水を吹き飛ばし靴を乾燥させることができる。 For example, when this water spraying device is used to remove mud adhering to shoes or the like, the trigger 12 is pulled toward the position where the tip of the spray nozzle 10 is adhering to mud, and a mixed fluid of compressed air, drain and water Spray to remove mud. Thereafter, the tip of the air nozzle 20 is directed to the shoe, the trigger 21 is pulled, and the shoe can be dried by blowing off water with compressed air containing no drain.

なお、本発明の噴霧装置は実施形態の水噴霧装置に限定されず、貯水槽１５に薬液、例えば消毒液などの水分を含んでも何ら問題ない液体を貯留して、圧縮空気と薬液およびドレンとを混合して噴霧するようにしてもよい。 The spraying device of the present invention is not limited to the water spraying device of the embodiment, and a liquid that has no problem even if it contains water such as a chemical solution, for example, a disinfecting solution, is stored in the water tank 15, and compressed air, chemical solution, and drain May be mixed and sprayed.

さらに、第２の空気配管８又は空気ホース１６に電磁弁を設け、電磁弁に作動信号を入力することにより弁体を開閉し、噴霧ノズル１０への圧縮空気の供給を開始又は停止する。このとき、混合部１１に内蔵し引き金２１の操作により作動する弁体は設ける必要はない。 Further, an electromagnetic valve is provided in the second air pipe 8 or the air hose 16, and an operation signal is input to the electromagnetic valve to open and close the valve body, and start or stop the supply of compressed air to the spray nozzle 10. At this time, it is not necessary to provide a valve body that is built in the mixing unit 11 and is operated by operating the trigger 21.

さらに、本実施形態の混合部１１は空気通路を圧縮空気が流通することで貯水槽の水を吸い上げるが、これに代えて水ホース１７に水ポンプを設け、混合部１１で圧縮空気と加圧水及びドレンを混合するようにしてもよい。 Furthermore, although the mixing part 11 of this embodiment sucks up the water of a water storage tank because compressed air distribute | circulates through an air path, it replaces with this and provides a water pump in the water hose 17, and in the mixing part 11, compressed air and pressurized water, Drain may be mixed.
