상기와 같은 문제점을 해결하기 위한 본 고안은, 슬러지를 포함하고 있는 유체를 저장하는 저류조와; 상기 저류조의 일 외측에 설치되며, 상기 저류조에 저장된 유체를 그 상부에 위치한 슬러지공급호퍼로 펌핑하는 펌프와; 상기 펌프를 통해 공급된 유체를 받아 일정 수위로 저장하고, 저장된 유체 중 일정 유량을 상기 수위의 압력차에 의해 연속적으로 외부로 배출하는 슬러지공급호퍼와; 상기 슬러지공급호퍼를 통해 일정량의 유체를 공급받아 유체에 포함된 슬러지의 수분을 제거하는 탈수장치를 가지고 있다.The present invention for solving the above problems, the storage tank for storing the fluid containing the sludge; A pump installed at one outside of the storage tank and pumping the fluid stored in the storage tank to a sludge supply hopper located at an upper portion thereof; A sludge supply hopper receiving the fluid supplied through the pump and storing the fluid at a predetermined level, and continuously discharging a predetermined flow rate of the stored fluid to the outside by the pressure difference of the level; It has a dewatering device that receives a certain amount of fluid through the sludge supply hopper to remove the water of the sludge contained in the fluid.

상기 슬러지공급호퍼는 수위를 일정하게 유지하기 위하여 일정 수위 이상일 때 유체를 상기 슬러지저류조로 배출하는 호퍼배출구와; 슬러지공급호퍼에 저장된 유체를 배출하는 호퍼밸브를 가지고 있다.The sludge supply hopper has a hopper outlet for discharging the fluid to the sludge storage tank when the water level is above a certain level to maintain a constant level; It has a hopper valve to discharge the fluid stored in the sludge feed hopper.

상기 탈수장치는 오폐수 속에 존재하는 침전물인 슬러지를 압착하여 수분을 제거하는 장치이다.The dewatering device is a device for compressing sludge which is a precipitate present in waste water to remove water.

이하 본 고안에 따른 실시예를 도면을 참조하여 보다 상세하게 설명하겠다.Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

도 2는 본 고안에 따른 실시예의 흐름도이고, 본 고안의 실시예는 슬러지를 포함하는 오수와 같은 유체를 저장하는 저류조(20)와, 저류조(20)의 오수를 펌핑하는 펌프(30)와, 펌프(30)를 통해 유체를 공급받아 탈수장치(50)에 일정량의 슬러지를 공급하는 슬러지공급호퍼(40)를 가지고 있다.2 is a flow chart of an embodiment according to the present invention, an embodiment of the present invention is a storage tank 20 for storing a fluid, such as sewage containing sludge, a pump 30 for pumping the sewage of the storage tank 20, The sludge supply hopper 40 receives the fluid through the pump 30 and supplies a certain amount of sludge to the dehydration device 50.

상기 저류조(20)는 하수관를 통해 유입된 오수를 모아서 저장하는 곳이다.The storage tank 20 is a place to collect and store the sewage introduced through the sewage pipe.

상기 펌프(30)는 일반적으로 유체를 펌핑할 때 사용되는 원심펌프이고, 저류조(20)의 오수를 펌핑하여 위치가 높은 슬러지공급호퍼(40)로 이동시킨다.The pump 30 is a centrifugal pump generally used to pump fluid, and pumps sewage from the storage tank 20 to a high sludge supply hopper 40.

슬러지공급호퍼(40)는 펌프(30)로부터 공급된 오수의 수위를 일정하게 유지하여, 슬러지공급호퍼(40) 내의 오수가 가지는 정수압(Hydrostatic Pressure)을 일정하기 위한 장치이다. 따라서 일정한 정수압을 가지는 오수는 슬러지공급호퍼(40)가 오수를 배출할 때 일정한 압력으로 배출되게 된다. 상기 슬러지공급호퍼(40)는일정 이상의 오수가 공급되었을 때, 초과한 오수를 다시 저류조(20)로 보내기 위한 호퍼배출구(42)와, 탈수장치(50)로 일정한 유량의 오수를 보내기 위한 호퍼밸브(44)를 가지고 있다.The sludge supply hopper 40 is a device for maintaining a constant water level of the sewage supplied from the pump 30, to constant the hydrostatic pressure of the sewage in the sludge supply hopper (40). Therefore, the sewage having a constant hydrostatic pressure is discharged at a constant pressure when the sludge supply hopper 40 discharges the sewage. The sludge supply hopper 40 has a hopper discharge port 42 for sending excess waste water back to the storage tank 20 when a predetermined amount of waste water is supplied, and a hopper valve for sending waste water of a constant flow rate to the dewatering device 50. Has (44)

상기 호퍼밸브(44)는 유량 조절밸브로서 일정 압력으로 배출되는 오수의 양을 조절한다.The hopper valve 44 adjusts the amount of sewage discharged at a constant pressure as a flow control valve.

상기 탈수장치(50)는 하수처리장에서 슬러지의 수분을 제거하기 위해 통상적으로 사용하는 장치로서, 수분을 배출시킬 수 있는 벨트사이로 오수를 유입시켜, 오수 안에 포함되어 있는 슬러지를 압착하여 수분을 제거한다. 탈수장치(50)는 통상적으로 사용되는 장치이므로 그 자세한 설명을 생략하기로 한다.The dehydration device 50 is a device that is commonly used to remove the water of the sludge in the sewage treatment plant, by introducing the sewage between the belt that can discharge the water, by pressing the sludge contained in the sewage to remove the water. . Since the dehydrator 50 is a commonly used device, its detailed description will be omitted.

이하, 본 고안에 따른 실시예의 작동과정을 도 2를 참조하여 보다 자세하게 설명하겠다.Hereinafter, the operation of the embodiment according to the present invention will be described in more detail with reference to FIG. 2.

먼저, 하수관을 통해 오수가 저류조(20)에 모이고, 펌프(30)는 저류조(20)의 오수를 슬러지공급호퍼(40)로 이동시킨다. 슬러지공급호퍼(40)는 일정 수위까지 오수를 담아서 저장하고, 일정 수위 이상이 되면 초과된 오수를 호퍼배출구(42)를 통해 저류조(20)로 다시 보내게 된다. 그리고 슬러지공급호퍼(40)에 저장된 오수는 정수압에 의해 일정 압력을 유지한 채로 호퍼밸브(44)를 통해 탈수장치(50)로 배출된다. 한편, 슬러지공급호퍼(40)는 호퍼밸브(44)를 통해 연속적으로 오수가 배출되기 때문에, 펌프(30) 역시 연속적으로 저류조(20)의 오수를 슬러지공급호퍼(40)로 공급하여야 한다.First, sewage is collected in the storage tank 20 through the sewage pipe, and the pump 30 moves the sewage of the storage tank 20 to the sludge supply hopper 40. The sludge supply hopper 40 stores and stores the sewage up to a predetermined level, and when the water level exceeds a predetermined level, the excess wastewater is sent back to the storage tank 20 through the hopper discharge port 42. And the sewage stored in the sludge supply hopper 40 is discharged to the dewatering device 50 through the hopper valve 44 while maintaining a constant pressure by the hydrostatic pressure. Meanwhile, since the sludge supply hopper 40 continuously discharges wastewater through the hopper valve 44, the pump 30 must also continuously supply the waste water of the storage tank 20 to the sludge supply hopper 40.

그리고 호퍼밸브(44)는 탈수장치(50)가 처리할 수 있는 양(㎥/hr)에 따라 오수의 양을 조절하여 탈수장치(50)에 공급하고, 탈수장치(50)는 오수에 함유되어 있는 슬러지를 압착하여 수분을 제거한다.And the hopper valve 44 is supplied to the dewatering device 50 by adjusting the amount of sewage in accordance with the amount (㎥ / hr) that can be treated by the dehydrating device 50, the dewatering device 50 is contained in the sewage Squeeze the sludge to remove moisture.

상기 슬러지공급호퍼(40)는 본 실시예처럼 하수처리장에 적용되었지만, 일정량의 유체를 연속적으로 공급하는 장치에 이용될 있다. 예를 들어 수돗물을 공급하는 정수장에서는 여과를 위하여 일정양의 약품이나 활성탄을 투입해야 하는바, 본 고안에서와 같이 슬러지공급호퍼(40)와 같은 구조를 통해 약품이나 활성탄을 공급할 수 있다.The sludge supply hopper 40 has been applied to the sewage treatment plant as in the present embodiment, but can be used in an apparatus for continuously supplying a certain amount of fluid. For example, in a water purification plant for supplying tap water, a certain amount of chemicals or activated carbon must be added for filtration, and thus, chemicals or activated carbon can be supplied through a structure such as a sludge supply hopper 40 as in the present invention.

이상에서 본 고안에 따른 실시예를 설명하였으나, 이는 예시이며, 본 고안의 정신을 벗어나지 않고 다양한 변화와 변형이 가능할 것이나, 이러한 변화와 변형은 본 고안의 권리범위에 속하게 됨은 첨부된 청구범위를 통해 이해할 수 있을 것이다.Although the embodiments according to the present invention have been described above, this is merely an example, and various changes and modifications may be made without departing from the spirit of the present invention, but such changes and modifications fall within the scope of the present invention through the appended claims. I can understand.

이상에서 살펴본 바와 같이 종래에 정량펌프에만 의존하여 유체의 양을 조절하였으나, 본 고안에 의한 유체공급구조는 슬러지공급호퍼에 의해 유체의 양을 조절하기 때문에, 정량펌프의 마모에 의해 발생하는 유량의 변화를 예방하는 장점을 가지고 있다.As described above, although the amount of fluid is controlled in accordance with the conventional metering pump only, the fluid supply structure according to the present invention regulates the amount of fluid by the sludge supply hopper, so that the amount of flow generated by abrasion of the metering pump It has the advantage of preventing change.

자세히 설명하면 종래에는 정량펌프를 통해 입자를 포함하는 일정량의 유체를 공급했기 때문에, 유체 안의 입자로 인해 정량펌프는 마모가 발생하고, 이 마모로 인해 정량펌프가 공급하는 유체의 양이 변하게 된다. 그러나 슬러지공급호퍼를 통해 일정량의 유체를 공급하면 펌프의 마모와 상관없이 일정한 양의 유체를 공급할 수 있다.In detail, since a certain amount of fluid including particles is supplied through the metering pump, the metering pump wears due to particles in the fluid, and the amount of fluid supplied by the metering pump changes due to the wear. However, if a certain amount of fluid is supplied through the sludge feed hopper, a certain amount of fluid can be supplied regardless of the wear of the pump.
