Abstract

본 발명은 편심 댐(dam) 조절 장치가 부착된 3상 원심 분리기에 관한 것이다.  The present invention relates to a three-phase centrifuge with an eccentric dam control device.

종래의 2상 원심분리기는 원심력에 의해 고체와 액체의 2상 분리는 용이하나, 산업용 폐유를 슬러지, 물, 기름처럼 3상으로 분리하는 방법으로는 할 수 없으며 종래의 2상 분리는 고,액체의 성상자체 효율도 매우 낮고 배출된 성분의 질도 떨어질 뿐만 아니라 물과 슬러지를 조절하기 위하여 작동중인 원심분리기를 정지시켜 유출 댐의 위치를 수동으로 조절해야 하는 등의 문제점이 다소 있었다.  Conventional two-phase centrifuges are easy to separate two-phase solids and liquids by centrifugal force, but cannot be used to separate industrial waste oil into three phases such as sludge, water, and oil. In addition to the very low efficiency and poor quality of the discharged components, there were some problems such as manually adjusting the location of the outflow dam by stopping the operating centrifuge to control water and sludge.

본 발명은 상기의 문제점을 해결하고자 안출한 것으로서,  The present invention has been made to solve the above problems,

이의 발명요지는 구동모터(10)의 작동에 따라 스크류 컨베이어(1)와 볼(bowl)(2)이 고속(2500~3000RPM)으로 회전시, 원수(폐유)를 투입한 후 일정시간이 경과하며 볼(2)내부에는 비중차이로 슬러지층, 수분층, 기름층이 각각 분리 형성되면, 상기 슬러지는 스크류 컨베이어(1)가 제거하여 고체 배출구(5)로 배출하고 수분(물)과 기름은 편심 조절댐(3)으로 분리 배출하는 것으로, 이는 이의 성상에 따라 작업자가 작동중에도 편심 댐 조절레버(4)를 간편하게 조절함으로써, 종래에 비하여 유수분리의 배출효율이 높고, 배출된 성분의 질이 양호하며 환경오염을 방지할 뿐만 아니라 폐에너지를 재활용함으로서 매우 경제적이고 실용적인 효과가 있는 것이다.  The invention of the invention is that when the screw conveyor (1) and the bowl (2) rotates at a high speed (2500 ~ 3000RPM) according to the operation of the drive motor 10, a predetermined time passes after the raw water (waste oil) is input When the sludge layer, the water layer, and the oil layer are separately formed due to the difference in specific gravity in the bowl 2, the sludge is removed by the screw conveyor 1 and discharged to the solid outlet 5, and the water (water) and oil are eccentrically controlled. It is separated and discharged to the dam (3), which is easy to adjust the eccentric dam control lever (4) even during operation by the operator according to its properties, the discharge efficiency of the oil and water separation is higher than the conventional, the quality of the discharged components is good In addition to preventing environmental pollution, recycling waste energy has a very economical and practical effect.

본 발명은 편심 댐 조절장치가 부착된 3상 원심분리기에 관한 것으로, 이를 보다 상세히 설명하면, 석유 정제시설중 탱크 하부의 침전 폐유와 산업용 폐유등을 수거하여 이를 3상(슬러지, 수분, 기름)으로 분리하여 산업용 에너지로 재활용할수 있는 장치에 관한 것이다.  The present invention relates to a three-phase centrifugal separator with an eccentric dam control device, which will be described in more detail. The three-phase (sludge, moisture, oil) is collected by collecting sediment waste oil and industrial waste oil at the bottom of a tank in an oil refining facility. The present invention relates to a device that can be separated and recycled into industrial energy.

종래의 2상 분리기는 고체와 액체의 2상 고액분리만 할 수 있어 3상으로 된 폐유를 분리하기에 어려움이 있었을 뿐만 아니라 액체 반출댐 조절구의 수위조절을 원심분리기의 작동중에는 할 수 없고 반드시 원심 분리기를 정지시킨 후 반출댐 커버 볼트를 풀어서 상기 반출댐 조절구의 수위를 적당하게 조절한 후 다시 볼트 체결하는 방식인 바 이는 작업시간이 많이 소요되고 작업성이 저하되는 등의 문제점이 있었다.  Conventional two-phase separators can only separate two-phase solid-liquid separation of solids and liquids, which makes it difficult to separate the three-phase waste oil, and it is impossible to control the level of the liquid discharge dam control during the operation of the centrifuge. After stopping the separator and unloading the discharge dam cover bolts to adjust the water level of the discharge dam control port appropriately and then fastening the bolts again, there was a problem such as a large amount of work time and workability is reduced.

본 발명은 상기의 문제점을 해결하고자 안출한 것으로서,  The present invention has been made to solve the above problems,

It is a device that allows the resources to be recycled by separating and discharging water and oil by simply adjusting the eccentric dam control lever (4) while checking the separate discharge property of oil and oil.

본 발명은 편심댐 조절장치가 부착된 3상 원심분리기에 관한 것으로, 이를 도면에 의거하여 상세히 설명하면 다음과 같다.  The present invention relates to a three-phase centrifuge with an eccentric dam control device, which will be described in detail with reference to the drawings.
