Only open so that some waste water is circulated before discharge.
이를 통해, 본 발명은 오수 배출 전에 오수를 순환시켜 충분히 교반시킨 후에 오수를 배출함과 아울러 배출 중에도 항상 오수를 지속적으로 순환시키도록 자동 제어하게 된다.Through this, the present invention is automatically controlled to circulate the sewage before the discharge of the sewage, and to discharge the sewage after fully stirring, and to continuously circulate the sewage during discharge.
필요에 따라 배출펌프(4), 제 1 및 제 2 개폐밸브(5,7)는 수동으로 조작 가능하도록 구성할 수도 있다.If necessary, the discharge pump 4 and the first and second on-off valves 5 and 7 may be configured to be manually operated.
또한, 본 발명에서는 저장탱크(1) 내에서 오수의 수위를 각각 감지하도록 설치되되 저장탱크(1) 저면으로부터 서로 이격되어 순차적으로 설치되는 제 1 내지 제 3 수위센서(9,10,11)와, 경보를 발생시키는 경보수단이 더 구비되고, 제어부(8)는 제 1 내지 제 3 수위센서(9,10,11)로부터 입력되는 검출신호에 따라 각 배출펌프(4)와 제 1 및 제 2 개폐밸브(5,7)의 가동 여부를 제어하도록 구성되는 데, 여기서, 제 1 수위센서(9)는 단일 배출펌프(4)의 가동 시점에 해당되는 수위인 제 1 수위의 도달 여부를 검출하고, 제 2 수위센서(10)는 양 배출펌프(4)의 가동 시점에 해당되는 제 2 수위를 검출하며, 제 3 수위센서(11)는 만수위로서 경보를 발생시키게 되는 수위인 제 3 수위를 검출하도록 구성된다.In addition, the present invention is installed to detect the water level of the sewage in the storage tank 1, respectively, the first to third water level sensors (9, 10, 11) and sequentially installed spaced apart from each other from the bottom of the storage tank (1) and In addition, the alarm means for generating an alarm is further provided, the control unit 8 is each discharge pump 4 and the first and second in accordance with the detection signal input from the first to third water level sensors (9, 10, 11) It is configured to control the operation of the on-off valves 5 and 7, wherein the first water level sensor 9 detects whether the first water level, which is the level corresponding to the operation time of the single discharge pump 4, has been reached. The second water level sensor 10 detects the second water level corresponding to the operation time of both the discharge pumps 4, and the third water level sensor 11 detects the third water level, which is the water level to generate an alarm as the full water level. It is configured to.
따라서, 저장탱크(1)의 바닥으로부터 제 1 수위센서(9), 제 2 수위센서(10) 및 제 3 수위센서(11)의 순으로 설치됨이 바람직하다.Therefore, it is preferable that the first level sensor 9, the second level sensor 10, and the third level sensor 11 are installed in order from the bottom of the storage tank 1.
구체적으로, 상기 제어부(8)는, 저장탱크(1) 내 오수의 도달 수위가 제 1 수위 미만인 경우에는, 일정 시간(Ta) 경과 여부를 판단하고, 일정 시간 Ta 이상 경과한 경우에는 배출펌프(4)를 가동시키고 제 1 개폐밸브(5)는 폐쇄되며 제 2 개폐밸브(7)는 개방되도록 제어한다.Specifically, the controller 8 determines whether or not a predetermined time Ta has elapsed when the sewage level of the sewage in the storage tank 1 is less than the first water level, and when the elapsed time Ta or more has elapsed, the discharge pump ( 4) and the first on-off valve 5 is closed and the second on-off valve 7 is controlled to open.
이 경우에는 저장탱크(1) 내 오수의 양이 소량이어서 오수의 배출이 필요 없으나, 장시간 동안 오수의 미배출로 인해 일어나는 침전물이 발생 및 경화 작용을 방지하기 위해 오수를 강제 순환시키는 것이다.In this case, since the amount of sewage in the storage tank 1 is small, it is not necessary to discharge the sewage. However, sediment occurring due to the undischarged sewage for a long time is forced to circulate the sewage to prevent the occurrence and curing action.
그리고 제어부(8)는, 도 4에 도시된 바와 같이, 저장탱크(1) 내 오수의 도달 수위가 제 1 수위 이상이고 제 2 수위 미만인 경우에, 단일 배출펌프(4)만 가동시키고 제 1 및 제 2 개폐밸브(5,7)가 개방되도록 제어하되, 이전에 일정 시간 Tb 동안 배출펌프(4)를 가동시키고 제 1 개폐밸브(5)는 폐쇄되며 제 2 개폐밸브(7)는 개방되도록 제어한다.And, as shown in FIG. 4, the controller 8 operates only a single discharge pump 4 when the water level reached in the storage tank 1 is greater than or equal to the first level and less than the second level. The second on-off valves 5 and 7 are controlled to be opened, but before the discharge pump 4 is operated for a predetermined time Tb, the first on-off valve 5 is closed and the second on-off valve 7 is controlled to open. do.
이 경우에는 저장탱크(1) 내 오수의 양이 많지 않으므로 단일 배출펌프(4)로만 오수의 배출이 이루어지며, 오수의 배출 전에 일정 시간 Tb 동안 오수를 순환시켜 저장탱크(1) 내의 오수를 교반시키게 된다.In this case, since the amount of sewage in the storage tank 1 is not large, the discharge of sewage is made only by a single discharge pump 4, and the sewage in the storage tank 1 is stirred by circulating the sewage for a predetermined time Tb before discharge of the sewage. Let's go.
그리고, 저장탱크(1) 내 오수의 도달 수위가 제 2 수위 이상이고 제 3 수위미만인 경우, 양 배출펌프(4)를 가동시키고 제 1 및 제 2 개폐밸브(5,7)가 개방되도록 제어하되, 이전에 일정 시간 Tc 동안 배출펌프(4)를 가동시키고 제 1 개폐밸브(5)는 폐쇄되며 제 2 개폐밸브(7)는 개방되도록 제어한다.In addition, when the water level of the sewage in the storage tank 1 is greater than or equal to the second level and less than the third level, the both discharge pumps 4 are operated to control the first and second on / off valves 5 and 7 to be opened. For example, the discharge pump 4 is operated for a predetermined time Tc, and the first on-off valve 5 is closed and the second on-off valve 7 is controlled to open.
이 경우에는 저장탱크(1) 내 저장된 오수의 양이 많으므로 양 배출펌프(4)로 오수의 배출이 이루어지며, 오수의 배출 전에 일정 시간 Tc 동안 오수를 순환시켜 저장탱크(1) 내의 오수를 교반시키게 된다.In this case, since the amount of stored sewage in the storage tank 1 is large, the discharge of sewage is made by both discharge pumps 4, and the waste water in the storage tank 1 is circulated for a predetermined time Tc before discharge of the sewage. It is stirred.
마지막으로, 저장탱크(1) 내 오수의 도달 수위가 제 3 수위 이상인 경우, 경보를 발생시킴과 함께 양 배출펌프(4)를 가동시키고 제 1 및 제 2 개폐밸브(5,7)를 모두 개방되도록 제어하는데, 저장탱크(1) 내 오수의 양이 과다한 경우(배출량에 비해 유입량이 과다한 경우)에는 오수를 순환시키는 예비과정을 생략하고 오수를 신속히 배출할 수 있도록 제어한다.Finally, when the sewage level of the sewage in the storage tank 1 is higher than or equal to the third level, an alarm is generated and both discharge pumps 4 are operated, and both the first and second on-off valves 5 and 7 are opened. If the amount of sewage in the storage tank (1) is excessive (inflow is excessive compared to the discharge amount), the preliminary procedure for circulating the sewage is skipped and the sewage can be discharged quickly.
예시적으로, Ta는 30일, Tb는 30분, Tc는 20분과 같이 정할 수 있는 데, Ta>Tb>Tc가 바람직하며, Tb>Tc로 하는 것은 저장된 오수의 양이 많은 경우에는 순환시간을 줄임으로써 신속히 오수를 배출하기 위한 것이다.For example, Ta may be set as 30 days, Tb as 30 minutes, and Tc as 20 minutes, and Ta> Tb> Tc is preferable, and Tb> Tc is a cycle time when the amount of stored sewage is large. To reduce the discharge of wastewater quickly.
