Description

この発明は、電車、列車、特に新幹線車両や長距離用の電車、列車に設置され、小便等の汚水を処理する車両用汚水処理装置に関する。   The present invention relates to a sewage treatment apparatus for vehicles which is installed in trains, trains, in particular, bullet trains, long-distance trains, trains, and treats sewage such as urine.

新幹線車両、長距離用電車、列車内に設置される小便用の車両用汚水処理装置では、従来、小便器にされた汚水が汚水管を経由して汚物タンクへ流す方式としては、汚水管の中間に１つの弁体を設け、重力による重力落下式或いは真空で吸引する真空吸引式の２通りの方式によって行われていたことが知られている。（従来技術１）   In sewage treatment equipment for urinals installed in Shinkansen vehicles, long-distance trains, and trains, the conventional method of flowing sewage into a urinal through a sewage pipe to a sewage tank is It is known that a single valve body is provided in the middle, and it has been carried out by two types of methods, that is, a gravity drop method using gravity or a vacuum suction method using vacuum suction. (Prior art 1)

更に、改良された小便用の車両用汚水処理装置は、真空圧送方式によるもので、小便器にされた汚水が汚水管を経由して一度中間タンクに入り、更に中間タンクに内圧を加えることにより汚水管から汚物タンクに流されている方式も知られていた。そしてこのような真空圧送方式は、中間タンクの上流側と下流側の汚水管にそれぞれ弁体を設け中間タンクを加圧減圧することにより汚水を、小便器から汚物タンクへ圧送する構造であった。（従来技術２）   Furthermore, the improved sewage treatment apparatus for vehicles for urine is based on the vacuum pressure feeding system, and the sewage made into the urinal once enters the intermediate tank via the sewage pipe and further applies internal pressure to the intermediate tank. There was also known a method in which the wastewater pipes flowed into the waste tank. And such a vacuum pumping system has a structure in which sewage is pumped from the urinal to the filth tank by providing a valve body in each of the upstream and downstream sewage pipes of the intermediate tank to pressurize and depressurize the intermediate tank. . (Prior art 2)

すなわち、従来技術２の小便用の車内用汚水処理装置は、第１段階として小便器が使用されると中間タンク内を減圧することにより、上流側弁体を開き、中間タンクへ汚水を吸引する。中間タンクに汚水が入ると、次に第２段階として上流側弁体を閉めてから中間タンク内を加圧し、次に下流側弁体を開いて汚水を中間タンクから汚物タンクへ圧送していた。また、特開平６−１９９２３４号公報（従来技術３）には高速走行を行なう新幹線車両は乗客の不快感（耳への不快感など）をなくすための車両用換気装置が開示されている。
特開平６−１９９２３４号公報（従来技術３） That is, the in-car sewage treatment apparatus for urine of Prior Art 2 opens the upstream valve body and sucks sewage into the intermediate tank by reducing the pressure in the intermediate tank when the urinal is used as the first stage. . When sewage enters the intermediate tank, the upstream valve body was closed as the second stage, and then the inside of the intermediate tank was pressurized. Next, the downstream valve body was opened and the sewage was pumped from the intermediate tank to the filth tank. . Japanese Laid-Open Patent Publication No. 6-199234 (Prior Art 3) discloses a vehicle ventilator that eliminates passenger discomfort (such as discomfort to the ear) of a high-speed Shinkansen vehicle.
Japanese Patent Laid-Open No. 6-199234 (Prior Art 3)

長距離用電車、列車内、に設置される小便用の車両用汚水処理装置、特に新幹線車両に設置される小便用の車両用汚水処理装置において、乗客が使用する小便器は車内に設置され、小便等の汚水が溜められる汚物タンクは車外の底部に設けられている。   In sewage treatment equipment for urinals installed on long-distance trains, in trains, and in particular in sewage treatment equipment for urinals installed in Shinkansen vehicles, urinals used by passengers are installed in the cars, A filth tank for collecting sewage such as urine is provided at the bottom of the vehicle.

そして乗客が使用する車内、特に高速走行を行う新幹線車両内は、乗客の耳等に感じる不快感を無くすため従来技術３に開示されているような車両用換気装置を使用して車内圧力が一定範囲で保たれている。しかし汚物タンクが設置されている車外底部は、この圧力調整が行なわれていない。 そのため高速列車同士のすれ違い時や車両のトンネルへの突入時やトンネル内に入り走行する状態になると、急激に汚物タンクにも高圧が掛かることになり、汚物タンク内の圧力も高くなる。例えば高速走行時の新幹線が明かり区間（通常の地上部）で、高速列車同士のすれ違い時の場合に、汚物タンクに掛かる圧力が通常の大気圧にプラスして４００ｍｍＡｑまで上がる状態も発生し、さらにトンネル突入時やトンネル内での走行時では、汚物タンクに掛かる圧力が大気圧にプラスして１２００ｍｍＡｑまで上がる状態も発生する可能性があった。   And in the inside of the Shinkansen that is used by passengers, especially in high-speed Shinkansen vehicles, the vehicle interior pressure is kept constant by using a vehicle ventilator as disclosed in Prior Art 3 in order to eliminate the discomfort felt by the passengers' ears. Kept in range. However, this pressure adjustment is not performed at the bottom of the vehicle where the filth tank is installed. Therefore, when the high-speed trains pass each other, when the vehicle enters the tunnel or enters the tunnel, the high pressure is also applied to the filth tank, and the pressure in the filth tank also increases. For example, when the high-speed Shinkansen is a light section (ordinary ground) and high-speed trains are passing each other, a state where the pressure applied to the filth tank increases to 400 mmAq in addition to the normal atmospheric pressure, When entering the tunnel or traveling in the tunnel, there is a possibility that the pressure applied to the waste tank increases to 1200 mmAq in addition to the atmospheric pressure.

この圧力により、上記従来技術１のように弁体が１つであると、トンネル内での走行等により汚物タンクへ高圧が掛かると、汚水管内の汚水が圧力の低い車内に設置された汚水受器である小便器へ逆流することがあるという問題点を有していた。特に汚水を流すために弁体を開けている状態のときに汚物タンクへ高圧が掛かると、汚水が逆流しやすい欠点があった。   Due to this pressure, if there is only one valve body as in the prior art 1, when a high pressure is applied to the waste tank due to traveling in the tunnel, the waste water in the waste water pipe is installed in the low pressure vehicle. In other words, there was a problem that the urinal may flow back to the urinal. In particular, when high pressure is applied to the filth tank when the valve body is opened in order to flow the sewage, the sewage tends to flow backward.

そして、従来技術２は、汚水管の中間に中間タンクを設け、その中間タンクの上流側と下流側にそれぞれ弁体を設けてあるため、汚物タンクからの逆流を防止することができ、従来技術１の問題点を克服した。   And since the prior art 2 has provided the intermediate tank in the middle of a sewage pipe, and has provided the valve body in the upstream and the downstream of the intermediate tank, respectively, the backflow from a filth tank can be prevented. Overcoming one problem.

しかし、、従来技術２は、中間タンクを減圧して小便器からの汚水を強制的に吸引して排出させるため、吸引作動時に汚水等とともに空気を吸引してしまい、そのときの空気摩擦による騒音が高い頻度で発生してしまう課題があった。   However, in the prior art 2, since the sewage from the urinal is forcibly sucked and discharged by depressurizing the intermediate tank, air is sucked together with the sewage during the suction operation, and noise caused by air friction at that time There is a problem that occurs frequently.

上記課題を解決するために、車両に設けられる車両用汚水処理装置において、
汚水受器から汚水を中間タンクまで送る上流側汚水管と、上流側汚水管の下流端に設けられる中間タンクと、中間タンクから汚水を汚物タンクまで送る下流側汚水管と、下流側汚水管の下流端に設けられる汚物タンクとを有し、
中間タンクの上流側に上流側開閉弁を設け、
中間タンクに、中間タンク内の圧力を加圧でき、また加圧を排圧して常圧にできる圧力調整装置と、中間タンク内圧を検知できるタンク内圧センサーとを設け、
中間タンクの下流側に下流側開閉弁を設けており、
上流側開閉弁と、圧力調整装置と、タンク内圧センサーと、下流側開閉弁は、それぞれ制御装置に接続しており、
汚水受器からの汚水を重力により中間タンクに落下させるとともに、中間タンクの汚水を中間タンク内に加える圧力によって汚物タンクまで圧送させることを特徴とする車両用汚水処理装置を提案する。 In order to solve the above problems, in a sewage treatment apparatus for a vehicle provided in a vehicle,
An upstream sewage pipe that sends sewage from the sewage receiver to the intermediate tank, an intermediate tank provided at the downstream end of the upstream sewage pipe, a downstream sewage pipe that sends sewage from the intermediate tank to the filth tank, and a downstream sewage pipe A waste tank provided at the downstream end,
An upstream on-off valve is provided upstream of the intermediate tank,
The intermediate tank is provided with a pressure adjustment device that can pressurize the pressure in the intermediate tank and exhaust the pressure to normal pressure, and a tank internal pressure sensor that can detect the intermediate tank internal pressure.
A downstream on-off valve is provided downstream of the intermediate tank,
The upstream side open / close valve, the pressure adjusting device, the tank internal pressure sensor, and the downstream side open / close valve are connected to the control device, respectively.
A sewage treatment apparatus for a vehicle is proposed, in which sewage from a sewage receiver is dropped into an intermediate tank by gravity and is pumped to a sewage tank by pressure applied to the intermediate tank.

更に、００１０欄記載の車両用汚水処理装置において、上流側開閉弁と下流側開閉弁の開閉状態が、２つの弁が同時に開口状態にならないように制御されている車両用汚水処理装置を提案する。   Furthermore, in the sewage treatment apparatus for vehicles described in the column 0010, a sewage treatment apparatus for vehicles is proposed in which the open / close states of the upstream side open / close valve and the downstream side open / close valve are controlled so that the two valves do not open simultaneously. .

この発明によれば、中間タンクを減圧して小便器からの汚水を吸引せず、重力によって中間タンクまで導くため、吸引時の空気騒音が発生しない効果がある。更に、中間タンクから汚物タンクへは、中間タンク内を加圧することによって速やかに圧送することができるとともに、汚水の圧送後は中間タンクの圧力を排出して常圧にすることができるため、次の小便器の使用による汚水も重力によって中間タンクまで導くことができる効果がある。   According to the present invention, since the intermediate tank is decompressed and the sewage from the urinal is not sucked and guided to the intermediate tank by gravity, there is an effect that no air noise is generated during suction. Furthermore, from the intermediate tank to the waste tank, it can be pumped quickly by pressurizing the inside of the intermediate tank, and after the pumping of the sewage, the pressure in the intermediate tank can be discharged to normal pressure. The sewage due to the use of urinals can be guided to the intermediate tank by gravity.

また、中間タンクの上流側と下流側にそれぞれ弁体を設け、２つの弁が同時に開口状態にならないように制御、又はほぼ交互に開閉を行うことにより、汚物タンクからの圧力の影響を車内にある小便器まで及ぼすことを防止することができる。   In addition, by providing valve bodies on the upstream side and downstream side of the intermediate tank, and controlling the two valves so that they do not open at the same time, or by opening and closing them almost alternately, the effect of pressure from the waste tank is brought into the vehicle. It is possible to prevent the urinal from being affected.

この発明の車両用汚水処理装置の実施形態に関し、模式説明図を示す図１及び作動状態を示すタイムチャートを示す図２に基づいて説明する。車両用汚水処理装置は、車両内に設けられる小便器である汚水受器１と、汚水管２と、汚物タンク３と、中間タンク４と、上流側開閉弁５と、下流側開閉弁６と、コントロールユニット（制御部）７、洗浄スイッチ８を有する。９は車内と車外を区分する部分であり、実施形態では車内床部分である。   An embodiment of the sewage treatment apparatus for vehicles according to the present invention will be described with reference to FIG. 1 showing a schematic explanatory view and FIG. 2 showing a time chart showing an operation state. The sewage treatment apparatus for vehicles includes a sewage receiver 1 which is a urinal provided in a vehicle, a sewage pipe 2, a filth tank 3, an intermediate tank 4, an upstream on-off valve 5, and a downstream on-off valve 6. A control unit (control unit) 7 and a cleaning switch 8. Reference numeral 9 denotes a portion that separates the inside of the vehicle from the outside of the vehicle, and in the embodiment, a portion of the inside floor of the vehicle.

汚水受器１は、この実施形態では大人用小便器であるが小児用小便器でもよい。汚水受器１は、上部に洗浄弁７２を設けた開閉自在の給水管７０を備えている。給水管７０は、その上流で給水タンク７１に接続しており、電磁開閉弁である洗浄弁７２が適宜の状態で開閉して汚水受器１に送水し汚水受器１を洗浄する。コントロールユニット７は、予め入力されたプログラムによって洗浄弁７２、洗浄スイッチ８、上流側開閉弁５、下流側開閉弁６に検知信号の受信や指示信号の送信を行う。洗浄スイッチ８は光電センサー或いは押しボタンスイッチ等からなるが、この実施例では光電センサーである。   The sewage receiver 1 is an urinal for adults in this embodiment, but may be a urinal for children. The sewage receiver 1 includes an openable and closable water supply pipe 70 provided with a cleaning valve 72 at the top. The water supply pipe 70 is connected to a water supply tank 71 upstream thereof, and a cleaning valve 72 that is an electromagnetic on-off valve opens and closes in an appropriate state to supply water to the sewage receiver 1 and clean the sewage receiver 1. The control unit 7 receives a detection signal and transmits an instruction signal to the cleaning valve 72, the cleaning switch 8, the upstream opening / closing valve 5, and the downstream opening / closing valve 6 according to a program inputted in advance. The cleaning switch 8 is composed of a photoelectric sensor or a push button switch. In this embodiment, the cleaning switch is a photoelectric sensor.

汚水管２は、汚水受器１から汚水を中間タンク４まで送る上流側汚水管２０と、上流側中間タンク４から汚水を汚物タンク３まで送る下流側汚水管２１とからなる。中間タンク４は、車内部分に配設される。   The sewage pipe 2 includes an upstream sewage pipe 20 that sends sewage from the sewage receiver 1 to the intermediate tank 4, and a downstream sewage pipe 21 that sends sewage from the upstream intermediate tank 4 to the filth tank 3. The intermediate tank 4 is disposed in the interior portion of the vehicle.

中間タンク４は、上流側汚水管２０の下流端部と上流側開閉弁５を介して接続し、下流側汚水管２１の上流端部と下流側開閉弁６を介して接続している。別の実施形態では、上流側開閉弁５は、中間タンク４より上流かつ汚水受器１より下流の位置に設けられればよく、下流側開閉弁６は、中間タンク４より下流かつ汚物タンク３より上流の位置に設けられればよい。   The intermediate tank 4 is connected to the downstream end of the upstream sewage pipe 20 via the upstream opening / closing valve 5, and is connected to the upstream end of the downstream sewage pipe 21 via the downstream opening / closing valve 6. In another embodiment, the upstream opening / closing valve 5 may be provided at a position upstream from the intermediate tank 4 and downstream from the sewage receiver 1, and the downstream opening / closing valve 6 is downstream from the intermediate tank 4 and from the waste tank 3. What is necessary is just to provide in an upstream position.

上流側開閉弁５及び下流側開閉弁６は、この実施例では電磁式エアスライドバルブとからなるスライド式開閉弁であるが、管路を開閉する弁であればボール弁等の他の開閉弁で構成してもよい。そして、上流側開閉弁５と下流側開閉弁６は、少なくとも互いの開口状態が同時には起こらないようにコントロールユニット７によって制御されている。すなわち、上流側開閉弁５が開口状態のときは、下流側開閉弁６は閉鎖状態であり、下流側開閉弁６が開口状態のときには上流側開閉弁５が閉鎖状態である。   The upstream side open / close valve 5 and the downstream side open / close valve 6 are slide type open / close valves comprising an electromagnetic air slide valve in this embodiment. You may comprise. The upstream opening / closing valve 5 and the downstream opening / closing valve 6 are controlled by the control unit 7 so that at least the mutual opening state does not occur at the same time. That is, when the upstream opening / closing valve 5 is open, the downstream opening / closing valve 6 is closed, and when the downstream opening / closing valve 6 is open, the upstream opening / closing valve 5 is closed.

中間タンク４には、中間タンク４内の圧力を加圧でき、また加圧を排圧して常圧にできる圧力調整装置４０と、中間タンク４の内圧を検知できるタンク内圧センサー４１とを設けている。７３はエアタンクであり、エアスライドバルブ及び中間タンク４へ圧力調整装置４０を介して接続している。   The intermediate tank 4 is provided with a pressure adjusting device 40 that can pressurize the pressure in the intermediate tank 4 and discharge the pressure to normal pressure, and a tank internal pressure sensor 41 that can detect the internal pressure of the intermediate tank 4. Yes. Reference numeral 73 denotes an air tank, which is connected to the air slide valve and the intermediate tank 4 via the pressure adjusting device 40.

汚物タンク３は、各汚水受器１からの汚水管２や図示しない汚物管等の下流側に接続され汚水、汚物を列車、電車使用中、貯留する装置である。汚物タンク３は、車体の底部８の下方の車外に配設され、車内の圧力調整を受けない。   The filth tank 3 is a device that is connected to the downstream side of the sewage pipe 2 from each sewage receiver 1 or a filth pipe (not shown) and stores the sewage and filth while the train or train is in use. The filth tank 3 is disposed outside the vehicle below the bottom 8 of the vehicle body and is not subjected to pressure adjustment inside the vehicle.

前記上流側開閉弁５と、圧力調整装置４０と、タンク内圧センサー４１と、下流側開閉弁６は、それぞれコントロールユニット７に接続している。コントロールユニット７によって上流側開閉弁５と下流側開閉弁６の開閉状態は、少なくとも２つの弁が同時に開口状態にならないように制御されている。他の実施例では、上流側開閉弁５と下流側開閉弁６の開閉状態は、互いに開閉が同じ状態にならないように制御されている。すなわち、上流側開閉弁５が開口状態のときは、下流側開閉弁６は閉鎖状態であり、上流側開閉弁５が閉鎖状態のときは、下流側開閉弁６は開口状態となる。   The upstream opening / closing valve 5, the pressure adjusting device 40, the tank internal pressure sensor 41, and the downstream opening / closing valve 6 are each connected to the control unit 7. The open / close state of the upstream side open / close valve 5 and the downstream side open / close valve 6 is controlled by the control unit 7 so that at least two valves are not simultaneously opened. In another embodiment, the open / close states of the upstream open / close valve 5 and the downstream open / close valve 6 are controlled so that the open / close states are not the same. That is, when the upstream side opening / closing valve 5 is in the open state, the downstream side opening / closing valve 6 is in the closed state, and when the upstream side opening / closing valve 5 is in the closed state, the downstream side opening / closing valve 6 is in the open state.

次に、この発明の実施形態の車両用汚水処理装置の作用について図２の作動タイムチャートに基づいて説明する。車内において、使用者の使用前の状態では、上流側開閉弁５及び下流側開閉弁６の両方とも閉鎖状態であり、中間タンク４内の圧力は常圧に近い圧力である。この状態で車両がトンネル内に入っても、上流側開閉弁５も下流側開閉弁６も閉鎖状態であるので汚物タンク３からの加圧はそこで止り、それより上流側へは波及しない。   Next, the operation of the sewage treatment apparatus for vehicles according to the embodiment of the present invention will be described based on the operation time chart of FIG. In the vehicle, both the upstream side open / close valve 5 and the downstream side open / close valve 6 are in a closed state before use by the user, and the pressure in the intermediate tank 4 is close to normal pressure. Even if the vehicle enters the tunnel in this state, both the upstream side open / close valve 5 and the downstream side open / close valve 6 are closed, so the pressurization from the waste tank 3 stops there, and does not spread upstream.

次に使用者が使用を始めると、光電センサーである洗浄スイッチ８がこの状態を検知しコントロールユニット７へ送信し上流側開閉弁５を開口させる。そして使用後に使用者が汚水受器１から離れると、光電センサーである洗浄スイッチ８がこの状態を検知しコントロールユニット７へ送信し洗浄弁７２を開口させ、給水管７０から汚水受器１へ給水し洗浄する。汚水は、重力により上流側汚水管２０から中間タンク４へ自然落下して、中間タンク内４で止められ溜まる。   Next, when the user starts using, the cleaning switch 8 which is a photoelectric sensor detects this state and transmits it to the control unit 7 to open the upstream side open / close valve 5. When the user leaves the sewage receiver 1 after use, the cleaning switch 8 which is a photoelectric sensor detects this state and transmits it to the control unit 7 to open the cleaning valve 72 and supply water from the water supply pipe 70 to the sewage receiver 1. Then wash. The sewage naturally falls by gravity from the upstream sewage pipe 20 to the intermediate tank 4 and is stopped and collected in the intermediate tank 4.

このときの洗浄弁７２の開口作動は、この実施例では３．５秒である。洗浄弁７２の閉鎖後、この実施例では洗浄弁７２の閉鎖の後に上流側開閉弁５が閉鎖する。その後、この実施例では上流側開閉弁５の閉鎖の後に中間タンク４へエアタンク７３から圧力調整装置４０を介してエアが送り込まれ加圧される。この加圧は、短時間で行われる。中間タンク４への加圧が停止すると同時に下流側開閉弁６が開口する。中間タンク４内が加圧された後直ぐに下流側開閉弁６が開口するため、中間タンク４内の汚水は、高圧力で下流側汚水管２１を経由して汚物タンク３へ落下する。   The opening operation of the cleaning valve 72 at this time is 3.5 seconds in this embodiment. In this embodiment, after the cleaning valve 72 is closed, the upstream side opening / closing valve 5 is closed after the cleaning valve 72 is closed. Thereafter, in this embodiment, after the upstream opening / closing valve 5 is closed, air is sent from the air tank 73 to the intermediate tank 4 via the pressure adjusting device 40 and pressurized. This pressurization is performed in a short time. At the same time as the pressurization to the intermediate tank 4 is stopped, the downstream opening / closing valve 6 is opened. Since the downstream on-off valve 6 opens immediately after the inside of the intermediate tank 4 is pressurized, the sewage in the intermediate tank 4 falls to the filth tank 3 via the downstream sewage pipe 21 at a high pressure.

下流側開閉弁６は、開口状態の後に閉鎖される。下流側開閉弁６の閉鎖後、中間タンク４の圧力調整装置４０が開口しタンク内からエアが抜け、中間タンク４内の圧力は常圧に戻る。   The downstream on-off valve 6 is closed after the open state. After the downstream opening / closing valve 6 is closed, the pressure adjusting device 40 of the intermediate tank 4 is opened, air is released from the tank, and the pressure in the intermediate tank 4 returns to normal pressure.

この状態は、使用者の使用前の状態（００２２欄参照）となり、順次使用者の使用により汚水は汚水受器１から重力による落下により中間タンク４内へ至り溜まる。以下順次同様の作用を繰り返す。これらの作動は、予めコントロールユニット７に入力したプログラムに従って自動的に行われる。   This state is a state before use by the user (see column 0022), and the sewage is gradually accumulated from the sewage receiver 1 into the intermediate tank 4 due to the drop of gravity by the user's use. The same action is repeated thereafter. These operations are automatically performed according to a program previously input to the control unit 7.

そのため、どのような状態でも車両がトンネル内に入っても、上流側開閉弁５か下流側開閉弁６のどちらかが閉鎖状態であるので、管内の加圧は、そこで止り、それより上流部へ波及しないため、汚水が汚水受器１内まで逆流することがない。   Therefore, even if the vehicle enters the tunnel in any state, since either the upstream side open / close valve 5 or the downstream side open / close valve 6 is closed, the pressurization in the pipe stops there, and the upstream part Therefore, the sewage does not flow back into the sewage receiver 1.

この発明は、電車、列車、特に新幹線列車、長距離用の電車、列車内に設置され利用される可能性が高い。   The present invention has a high possibility of being installed and used in trains, trains, in particular, Shinkansen trains, long-distance trains, and trains.
