본 고안은 에어펌핑(Air Pumping)장치에 관한 것으로, 보다 상세하게 설명하면 강산이나 강 알칼리등과 같은 폐수처리장이나 또는 지하수의 펌핑(Pumping)시에 폐수조내에 개폐장치가 착설된 폐수수집물통을 설치하여 에어(Air)를 공급함으로써 침전된 폐수를 용이하게 배출할 수 있도록 한 에어펌핑장치에 관한 것이다.The present invention relates to an air pumping device, and more specifically, to a wastewater treatment plant such as a strong acid or a strong alkali, or a wastewater collection tank having an opening and closing device installed in a wastewater tank during pumping of groundwater. The present invention relates to an air pumping device which is installed to supply air to easily discharge sedimented wastewater.
종래의 폐수처리장등과 같은 곳에 설치되는 펌프장치에 있어서는, 산세척작업중에 발생되는 산 폐수 및, 산을 회수하는 설비에서 발생되는 산 폐수를 중화 및 산화, 침전처리하는 공정에서 산폐수를 이송시키도록 사용된다. 즉 산폐수가 처리장에 유입되면, 중화조에서 수집한 후, 소석회를 투입하여 이를 중화 및 침전시킨 다음 수중펌프를 설치하여 상등수는 펌핑작용에 의해 방류시키고, 하부의 침전물은 침전물 펌프(Sludge Pump)를 이용하여 필터프레스(Filter Press)(미도시)에서 덩어리 상태로 가압하여 소각장으로 이송처리하는 경우가 대부분이다.In a pump device installed in a conventional wastewater treatment plant or the like, acid wastewater generated during pickling operations and acid wastewater generated in an acid recovery facility are neutralized, oxidized and precipitated. It is used to That is, when acid wastewater enters the treatment plant, it is collected in a neutralization tank, neutralized and precipitated by adding lime, and then a submersible pump is installed to discharge the supernatant water by a pumping action, and the lower sediment is a sludge pump. In most cases, it is pressurized in a lump state by using a filter press (not shown) to transfer to an incinerator.
그러나, 상기와 같은 폐수처리조에 있어서는, 산 폐수의 중화작업 불량시 수중 펌프가 부식하며, 산의 부식에 의하 고장이 빈번하여 중화조내에서의 폐수처리 작업에 커다란 어려움이 있음은 물론, 고농도의 폐수처리는 거의 불가능한 단점이 있었다.However, in the wastewater treatment tank as described above, when the acid wastewater neutralization work is poor, the submersible pump is corroded, and failure due to acid corrosion frequently causes great difficulty in the wastewater treatment operation in the neutralization tank, as well as high concentration wastewater. The treatment had an almost impossible disadvantage.
또한, 수중펌프를 설치하는 경우에도 다량의 침전물을 포함한 고농도의 폐수는 쉽게 외부로 배출되지 않고, 수중펌프의 파손을 초래하여 연속적인 폐수처리작업이 이루어질 수 없는 문제점도 갖춘 것이었다.In addition, even in the case of installing an underwater pump, a high concentration of wastewater containing a large amount of sediment is not easily discharged to the outside, and it causes a damage of the underwater pump, and thus, a continuous wastewater treatment operation cannot be performed.
본고안은 상기와 같은 종래의 문제점을 해소하기 위하여 안출된 것으로서, 산의 부식에 의해 파손되지 않고, 간단한 구조를 갖추면서 내부에 큰 부압을 발생시켜 다량의 침전물을 포함한 고농도의 폐수를 쉽게 폐수처리조의 외부로 배출시킴으로서 폐수처리작업을 용이하게 수행할 수 있도록 된 에어펌핑장치를 제공함에 그 목적이 있다.This paper was devised to solve the above-mentioned conventional problems, and it is not damaged by acid corrosion, but has a simple structure and generates a large negative pressure inside to easily treat wastewater of high concentration including a large amount of sediment easily. It is an object of the present invention to provide an air pumping device capable of easily performing wastewater treatment operations by discharging to the outside of the tank.
상기 목적을 달성하기 위하여 본 고안은, P.P, PVC 또는 P.E로 이루어진 내산재의 폐수수집물통내에 압력조정 밸브 및 압력계가 상측에 설치된 에어공급배관이 연결되고, 상기 폐수수집물통의 일측에는 폐수 유입통로가 형성되며, 상단부에는 폐수유출통로가 형성되어 상기 폐수수집물통내로 유입된 폐수를 공기의 압력으로 연속적으로 펌핑하여 외부로 배출시키도록 된 에어펌핑장치에 있어서, 상기 폐수유입 통로에는 내산재로 된 탄력성 고무판으 갖춘 개폐장치가 장착됨을 특징으로 하는 에어펌핑장치를 마련함에 의한다.In order to achieve the above object, the present invention is connected to an air supply pipe having a pressure control valve and a pressure gauge installed at an upper side in a wastewater collection container made of PP, PVC or PE, and at one side of the wastewater collection container. Is formed in the upper end of the wastewater flow passage is formed in the air pumping device to discharge the wastewater introduced into the wastewater collection tank by continuously pumping the pressure of air to the outside, the wastewater inflow passage is made of acid-resistant By providing an air pumping device characterized in that the opening and closing device equipped with a resilient rubber plate.
이하, 첨부된 도면에 의거하여 본 고안의 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 의한 에어펌핑장치를 폐수조내에 설치한 상태를 도시한 정단면도로서, P.P, PVC 또는 P.E로 이루어진 내산재의 폐수수집물통(1)내에 압력계(2) 및 압력조절밸브(3)가 상측에 착설한 에어공급배관(5)을 설치하고, 상기 폐수수집물통(1)의 일측인 폐수유입통로에는 탄력성있는 고무판(6)이 장착된 개폐장치(7)를 설치하여 상측의 폐수유출통로(8)를 통해 폐수를 유출토록 한 구성으로 이루어진다.1 is a front sectional view showing a state in which an air pumping apparatus according to the present invention is installed in a waste water tank, and includes a pressure gauge 2 and a pressure regulating valve in a wastewater collection container 1 made of PP, PVC, or PE. 3) the air supply pipe 5 installed on the upper side is installed, and the wastewater inflow passage, which is one side of the wastewater collection container 1, is provided with an opening and closing device 7 equipped with an elastic rubber plate 6, The wastewater outflow passage (8) is made of a configuration to let the wastewater outflow.
다라서, 제2도(a) 및 (b)에 도시된 폐수수집물통(Bucket)에서와 같이 폐수조(4)내에 저장중인 강산 또는 강알칼리성 폐수의 액체는 폐수조(4)의 저부로 침전된 후 개폐장치(7)를 통하여 폐수수집물통(1)내로 유입되며, 이때 작업자가 압력조절밸브(3)를 열게되면, 에어공급배관(5)을 따라 적정량의 에어가 폐수수집물통(1)내로 공급된다. 한편, 폐수수집물통(1)내에서는 유입된 에어로 인하여 개폐장치(7)의 고무판(6)이 닫히게 되어 내부의 폐수가 외부로 배출되는 역류현상이 방지된다.Therefore, the liquid of the strong acid or strong alkaline wastewater being stored in the wastewater tank 4, as in the wastewater bucket shown in Figs. 2 (a) and (b), settles to the bottom of the wastewater tank (4). After being introduced into the wastewater collection container 1 through the opening and closing device 7, when the operator opens the pressure control valve 3, an appropriate amount of air is discharged along the air supply pipe 5 to the wastewater collection container 1. Are fed into. On the other hand, in the wastewater collection container (1), the rubber plate (6) of the opening and closing device (7) is closed due to the introduced air, thereby preventing the backflow phenomenon in which the internal wastewater is discharged to the outside.
따라서, 에어공급배관(5)을 통해 유입된 에어는 폐수수집물통(1)의 상부측에 형성된 폐수배출통로(8)를 통하여 빠른속도로 연속적으로 배출되며, 이러한 에어의 배출작동은 폐수수집물통(1)내부에 큰 부압을 발생시킴으로서 폐수배출통로(8)에 인접한 폐수는 에어와 함께 폐수배출통로(8)로 빠져나가게 되고, 폐수수집통(1)의 하부에 위치한 폐수유입통로의 개폐장치(7)는 고무판(6)이 열려지면서 폐수수집물통(1)으로 빠져나간 만큼의 폐수가 연속적으로 유입되어 펌핑(Pumping)작용이 이루어지게 되는 것이다.Therefore, the air introduced through the air supply pipe (5) is continuously discharged at a high speed through the wastewater discharge passage (8) formed on the upper side of the wastewater collection container (1), the discharge operation of such air is the wastewater collection container (1) By generating a large negative pressure inside, the wastewater adjacent to the wastewater discharge passage 8 exits the wastewater discharge passage 8 together with the air, and the opening and closing device of the wastewater inflow passage located below the wastewater collection passage 1 (7) is the rubber plate 6 is opened as the wastewater is continuously introduced into the wastewater collection container (1) is to be pumped (Pumping) is made.
상기에서와 같이 본 고안의 에어펌핑장치에 의하면, 내산재로 이루어진 폐수수집물통(1)을 폐수조내에 설치하고, 에어공급배관(5)을 연결하여 에어를 공급시킴으로써 상기 폐수수집물통(1)내의 침전된 폐수를 외부로 배출토록 하여 중화조내의 고농도 폐수의 처리시 수중펌프를 별도로 설치해야 하는 번거로움 및 불편함을 해소할 수 있음은 물론, 상기 폐수수집물통(1)내로 에어가 유입되는 경우, 침전물을 포함한 폐수가 역류되어 외부로 배출되는 현상을 개폐장치(7)의 고무판(6)이 효과적으로 차단하기 때문에, 에어는 고농도의 폐수와 함께 폐수배출통로(8)를 통하여 빠른속도로 배출될 수 있고, 이에 따라서 폐수수집물통(1)내에는 큰 부압이 생성되어 개폐장치(7)의 고무판(6)이 열리면서 연속적으로 폐수의 유입작동이 이루어지게 된다.According to the air pumping device of the present invention as described above, by installing the wastewater collection container (1) made of acid-resistant in the wastewater tank, by connecting the air supply pipe (5) to supply air to the wastewater collection container (1) By discharging the sewage within the wastewater to the outside, it is possible to solve the inconvenience and inconvenience of having to install an underwater pump separately in the treatment of the high concentration wastewater in the neutralization tank, as well as the inflow of air into the wastewater collection tank 1. In this case, since the rubber plate 6 of the switchgear 7 effectively blocks the discharge of wastewater including sediment back to the outside, the air is discharged at high speed through the wastewater discharge passage 8 together with the high concentration of wastewater. Accordingly, a large negative pressure is generated in the wastewater collection container 1 so that the rubber plate 6 of the opening and closing device 7 is opened to continuously operate the inflow of wastewater.
따라서, 본 고안에 의하면 다량의 침전물을 포함한 고농도의 폐수를 에어를 이용한 펌핑작용으로 쉽게 폐수처리조의 외부로 배출시킴으로써 폐수처리작업을 연속적으로 수행할 수 있게되는 실용상의 효과를 얻는다.Therefore, according to the present invention, a high concentration of wastewater containing a large amount of sediment is easily discharged to the outside of the wastewater treatment tank by the pumping action using air, thereby obtaining a practical effect of being able to continuously perform the wastewater treatment operation.
