【0002】[0002]

【従来の技術】[Prior art]

高温高圧滅菌装置は、図1や図2に示すように、耐圧構造の滅菌タンク5の中 に被処理原水を所定水量だけ導入し、密封した後に、滅菌タンク5内に配置した 電気ヒーター7や滅菌タンクを囲むように配置した蒸気配管などの加熱手段によ り加熱し、高温高圧状態に所定時間保持して、被処理原水に含まれる細菌及びウ イルスなどを死滅させる。その後に、排水用導管から下水などへ排出する。 As shown in FIG. 1 and FIG. 2, the high-temperature high-pressure sterilizer introduces a predetermined amount of raw water to be treated into a sterilization tank 5 having a pressure resistant structure, seals it, and then installs an electric heater 7 or the like placed in the sterilization tank 5. The sterilization tank is heated by a heating means such as a steam pipe and kept at high temperature and high pressure for a predetermined time to kill bacteria and viruses contained in the raw water to be treated. After that, it is discharged from the drainage pipe to sewage.

【0003】 高温高圧滅菌装置の従来の水位調整手段は、図2に示すように、滅菌タンク5 の中に水位センサー14を配置して滅菌タンク内の水位を検知し設定水位に達す ると水位制御器により汲み上げポンプ3及び第1の制御弁4のON/OFF及び 開/閉を制御する。As shown in FIG. 2, the conventional water level adjusting means of the high temperature high pressure sterilizer has a water level sensor 14 arranged in the sterilization tank 5 to detect the water level in the sterilization tank and reach the set water level when the water level is reached. The controller controls ON / OFF and opening / closing of the pumping pump 3 and the first control valve 4.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかし、滅菌タンクの中にあるために、水位センサーやその配線も高温高圧に さらされる。その結果、水位検知の誤りや水位センサーなどの劣化が生じやすい という問題がある。 However, since it is in the sterilization tank, the water level sensor and its wiring are also exposed to high temperature and high pressure. As a result, there are problems that water level detection is erroneous and that water level sensors and other components are prone to deterioration.

【問題を解決するための手段】[Means for solving the problem]

上記問題点は、請求項1に記載の考案、すなわち、原水貯槽内の底部近くから 滅菌タンクまでを原水導入管により連結し、その間に順番に汲み上げポンプと第 1の制御弁とを配置し、滅菌タンクから原水貯槽の上方までをオーバーフロー管 により連結し、その間に順番に第2の制御弁と水流センサーとを配置し、滅菌タ ンクへの原水導入管の連結位置を、滅菌タンクへのオーバーフロー管の連結位置 よりも高水位とした高温高圧滅菌装置用の水位調整手段によって、解決される。 The above-mentioned problem is the device according to claim 1, that is, the vicinity of the bottom of the raw water storage tank to the sterilization tank is connected by a raw water introduction pipe, and a pumping pump and a first control valve are arranged between them in order. An overflow pipe is connected from the sterilization tank to the upper part of the raw water storage tank, and a second control valve and a water flow sensor are arranged between them in order to connect the connection position of the raw water introduction pipe to the sterilization tank to the sterilization tank. This is solved by the water level adjusting means for the high temperature high pressure sterilizer, which has a higher water level than the connecting position of the pipe.

【作用】[Action]

滅菌タンク5の設定水位にオーバーフロー管21を連結する。一方、原水導入 管20は設定水位より高い位置で滅菌タンク5に連結されている。まず、第1の 制御弁4及び第2の制御弁10をともに開き、汲み上げポンプ3を作動して、原 水貯槽1から滅菌タンク内へ原水2を汲み上げる。滅菌タンク内の原水6の水位 が設定水位に達すると、オーバーフロー管21を通って原水があふれ始め、水流 センサー11によって検知される。あふれた原水はオーバーフロー管21を通っ て原水貯槽1へと戻る。水流センサー11の検知信号によって、汲み上げポンプ 3が停止し、第1の制御弁4が閉じる。その後に、水流センサー11が水流を検 知しなくなった時に、第2制御弁10を閉じて、滅菌タンク5を密閉する。そし て、滅菌タンク内の原水の加熱滅菌処理を開始する。 The overflow pipe 21 is connected to the set water level of the sterilization tank 5. On the other hand, the raw water introduction pipe 20 is connected to the sterilization tank 5 at a position higher than the set water level. First, both the first control valve 4 and the second control valve 10 are opened, the pump 3 is operated, and the raw water 2 is pumped from the raw water storage tank 1 into the sterilization tank. When the water level of the raw water 6 in the sterilization tank reaches the set water level, the raw water begins to overflow through the overflow pipe 21 and is detected by the water flow sensor 11. The overflowed raw water returns to the raw water storage tank 1 through the overflow pipe 21. The pumping pump 3 is stopped by the detection signal of the water flow sensor 11, and the first control valve 4 is closed. After that, when the water flow sensor 11 no longer detects the water flow, the second control valve 10 is closed and the sterilization tank 5 is sealed. Then, heat sterilization of raw water in the sterilization tank is started.

【実施例】【Example】

図2に示すように、原水導入管20の開放端は原水貯槽1の中の底部近くに配 置され、原水貯槽内の原水2を開放端から吸い込んで汲み上げる。原水導入管2 0の他端は滅菌タンク5の壁に連結されている。その途中には上流からの順で汲 み上げポンプ3と第1の制御弁4が取り付けられている。汲み上げポンプ3の作 動、停止は、水位制御器12によって、制御される。また、第1の制御弁4の開 閉も水位制御器12によって、制御される。滅菌タンク5は耐圧構造であり、内 部に電気ヒーター7を備えている。滅菌タンク5の頂部には配管22を介して安 全弁8が取り付けられており、設定圧力を越えると安全弁8が開放して滅菌タン ク内の圧力を自動的に低下させる働きをする。滅菌タンク5の底部には排水用導 管23が連結されている。排水用導管23の他方の開放端は下水の上方に配置さ れており、加熱滅菌処理後の水を下水に排出するとともに、下水からの逆流が生 じないように図られている。排水用導管23には第3の制御弁9が取り付けられ ている。さらに、滅菌タンク5の壁の設定水位にオーバーフロー管21が連結さ れている。オーバーフロー管21の他端は、原水貯槽1の上方に配置されており 、その途中には上流からの順で第2の制御弁10と水流センサー11が配置され ている。設定水位を超えると、滅菌タンク内の水の一部はオーバーフロー管21 を通って原水貯槽1へと戻る。その際に、水流センサー11によって水の流動が 検知される。水流センサー11からの検知信号は水位制御器12に入力される。 第2の制御弁10の開閉は水位制御器12によって制御される。電気ヒーター7 への通電はタイマー13によって制御され、第3の制御弁の開閉もまたタイマー 13によって制御されている。水位制御器12とタイマー13との間には相互に 信号のやり取りを行うことができる。 As shown in FIG. 2, the open end of the raw water inlet pipe 20 is arranged near the bottom of the raw water storage tank 1, and the raw water 2 in the raw water storage tank is sucked from the open end and pumped up. The other end of the raw water introduction pipe 20 is connected to the wall of the sterilization tank 5. A pump 3 and a first control valve 4 are attached in the middle of the pump in order from the upstream side. The water level controller 12 controls the operation and stop of the pumping pump 3. The opening / closing of the first control valve 4 is also controlled by the water level controller 12. The sterilization tank 5 has a pressure resistant structure and is equipped with an electric heater 7 inside. A safety valve 8 is attached to the top of the sterilization tank 5 through a pipe 22. When the set pressure is exceeded, the safety valve 8 opens to automatically reduce the pressure in the sterilization tank. A drainage conduit 23 is connected to the bottom of the sterilization tank 5. The other open end of the drainage conduit 23 is arranged above the sewage, and is designed to discharge the water after the heat sterilization process into the sewage and prevent backflow from the sewage. A third control valve 9 is attached to the drainage conduit 23. Further, an overflow pipe 21 is connected to the set water level on the wall of the sterilization tank 5. The other end of the overflow pipe 21 is arranged above the raw water storage tank 1, and a second control valve 10 and a water flow sensor 11 are arranged in the middle thereof in the order from the upstream side. When the set water level is exceeded, part of the water in the sterilization tank returns to the raw water storage tank 1 through the overflow pipe 21. At that time, the water flow sensor 11 detects the flow of water. The detection signal from the water flow sensor 11 is input to the water level controller 12. The opening and closing of the second control valve 10 is controlled by the water level controller 12. Energization of the electric heater 7 is controlled by the timer 13, and opening / closing of the third control valve is also controlled by the timer 13. Signals can be exchanged between the water level controller 12 and the timer 13.

【考案の効果】[Effect of device]

本考案の水位調整手段においては、制御弁を閉じて滅菌タンクを密閉し、加熱 する時に、センサーが制御弁の外側に位置するので、センサーが加熱されること がない。その結果として、センサーが誤動作したり、劣化したり、故障したりす ることが起こりにくいという効果がある。 In the water level adjusting means of the present invention, when the sterilization tank is closed by closing the control valve and heating is performed, the sensor is located outside the control valve, so that the sensor is not heated. As a result, the sensor is less likely to malfunction, deteriorate, or fail.
