본 고안은 분뇨 종합처리 과정에서 분뇨속에 혼합된 각종 협잡물을 제거한 액체 가운데 함유된 토사류를 분리, 제거하는 장치에 관한 것이다.The present invention relates to a device for separating and removing the earth and sand contained in the liquid to remove various contaminants mixed in the manure during the comprehensive manure process.

우리나라의 분뇨는 선진 외국에 비해 각종 협잡물과 토사류가 과다하게 함유되어 있는바 분뇨중 토사류 함량에 있어 일본국의 경우는 0.03-0.05%이고, 한국은 0.3-0.5%로서 약 10배 달하고 있다고 한다.Korea's manure contains more contaminants and sediments than developed foreign countries. The content of soil in manure is 0.03-0.05% in Japan, and 0.3-0.5% in Korea.

이와 같은 다량의 토사류는 본처리조(저류조, 폭기조, 소화조)에 흘러 들어가서 침전, 퇴적하여 본처리조의 실제 용량을 감소시켜 처리 효율을 저하시킴을 물론 배관의 폐쇄현상을 야기시키는 등의 요인이 되고 있는 것이다.Such a large amount of soil flows into the main treatment tank (storage tank, aeration tank, and digestion tank) to settle and accumulate, reducing the actual capacity of the treatment tank, reducing treatment efficiency and causing pipe closing. It is.

따라서 본 처리조(분뇨 저류조, 폭기조, 소화조등)에 침전, 퇴적된 토사류의 제거를 위해 1-2년에 한번씩 수일간은 처리장의 가동을 중지하고 처리조에 퇴적된 토사류를 인위적으로 제거해야 하는 많은 어려움을 겪고 있는 것이다.Therefore, in order to remove sediment and sediment deposited and deposited in the treatment tank (manure storage tank, aeration tank, digestion tank, etc.), it is necessary to stop the operation of the treatment plant every one or two days for several days and to artificially remove the soil deposited on the treatment tank. I'm having a hard time.

이와 같은 토사류의 제거를 위해 액체 사이크론을 이용할 경우 대부분의 토사류는 분리해 낼 수 있으나 분리된 토사류 중에는 모래의 양보다 더 많은 양의 액체(수분)가 섞여져 있어 이를 다시 일광으로 장시간 건조시켜야 하는 문제점이 있고, 또한 액체 사이크론에서 포집된 모래를 단속적으로 제거해낼 경우는 밸브와 이송관이 폐쇄되는 현상으로 말미암아 원활한 배출이 이루어지지 않는 폐단이 생긴다.When liquid cyclones are used to remove such soils, most soils can be separated, but the separated soils contain more liquid (moisture) than sand, which must be dried for a long time in daylight. There is a problem, and when the sand collected from the liquid cyclone is intermittently removed, the valve and the transfer pipe are closed, resulting in a closed end where smooth discharge is not achieved.

즉, 수분을 많이 함유하고 있는 모래는 물의 분자력이 작용하기 때문에 정체후 이를 배출시킬 때 상협하광형상인 즉, 위가 좁고 아래 부분이 넓은 원추형의 수직관에서도 흘러내리지 않고 관내벽에 부착되는 현상이 생긴다.In other words, the sand containing a lot of water acts on the molecular wall of water, so when it is stagnated, it is in the form of a sub-neolitic light, that is, a phenomenon in which the upper part is attached to the inner wall of the pipe without flowing down even in a narrow conical vertical tube. Occurs.

그리고 모래의 탈수를 위해 원심 분리기를 사용할 경우는 물이 거의 함유되지 않는 모래만을 분리해 낼 수 있으나 이는 처리량이 너무 적어서 경제성이 없게 된다.And if the centrifuge is used for the dewatering of the sand can be separated only the sand containing little water, but this is too low throughput economical.

예컨데 1일 100㎘ 정도의 분뇨를 처리하는 소도시의 분뇨 처리장에서 원심 분리기만으로 모래를 분리 수거하려면 시간당 4㎘ 처리 용량의 중형 원심 분리기를 8시간 기준하여 4대를 장치하고 이를 동시에 가동시켜야 하기 때문에 이는 비현실적인 방법으로서 경제성이 거의 없는 것이다.For example, in order to separate and collect sand using a centrifuge only in a manure treatment plant in a small city where 100 manure is processed per day, four medium centrifuges each having a processing capacity of 4 kW per hour must be installed and operated simultaneously. It is unrealistic and there is little economic feasibility.

따라서 액체 사이크론 또는 원심 분리기는 이를 분뇨속에 함유된 모래 제거용으로 사용할 경우에 있어 어느 하나만으로는 소기의 목적을 달성할 수 없기 때문에 본 고안은 이점을 감안하여 액체 사이크론과 원심 분리기를 유기적으로 결합함으로써 충분히 탈수된 모래를 연속적으로 분리해 낼 수 있는 기늘능과 아울러 경제성이라는 두가지 효과를 동시 수행할 수 있게 한 것으로 이는 0.5+0.5=1이 아니고 2가 되는 상승 효과를 얻고자 한 것이다.Therefore, when the liquid cyclone or centrifuge is used to remove the sand contained in the manure, the present invention cannot combine the liquid cyclone with the centrifuge. By doing so, it is possible to simultaneously perform two effects of economic efficiency as well as economic ability to separate sufficiently dehydrated sand, which is to achieve a synergistic effect of 2, not 0.5 + 0.5 = 1.

이를 도면에 의거 상세히 설명하면 다음과 같다.This will be described in detail based on the drawings.

회전식 격차 장치된 공지한 여과기(1)와 사이크론(3)사이에는 모터펌프(2)를 개재한 이송관(2')이 설치되고, 사이트론(3)의 상부에 연결된 이송관(4')의 선단에는 본처리 공정인 저류조(4)가 설치되며 사이크론(3)의 저면에 연결된 이송관(3')의 선단에는 유입관(6')이 연결되고, 유입관(6')의 주면에는 모터(5")와 연동되는 풀리 (5)(5')가 설치되어 있으되 풀리(5)에는 스크류(7)의 중공축(7')이 연결되고, 풀리(5')에는 후방에 분산판(10')이 있는 지지축간(10)이 개재된 원심 분리기(6)의 실린더(8)가 연결되어 있으되 실린더(8)의 폴리(5')는 스크류 중공축(7')과 연결된 풀리(5)보다 약간느린 속도로 회동되게 하였으며 스크류 중공축(7')에는 다수의 통공(7")이 뚫림되고 앞측 원추부에는 다수의 모래 배츨공(8")이 뚫림되어진 구조이다.Between the well-known filter (1) and the cyclone (3) equipped with a rotary gap, a transfer pipe (2 ') via a motor pump (2) is installed, and a transfer pipe (4') connected to the upper portion of the sight (3) At the front end of the inlet), a storage tank 4, which is a main treatment process, is installed, and an inlet pipe 6 'is connected to the front end of the transfer pipe 3' connected to the bottom of the cyclone 3, and the inlet pipe 6 ' The main surface is provided with pulleys 5 and 5 'which are interlocked with the motor 5 ", but the hollow shaft 7' of the screw 7 is connected to the pulley 5, and to the rear of the pulley 5 '. The cylinder 8 of the centrifugal separator 6 interposed between the supporting shafts 10 with the distribution plate 10 'is connected, but the poly 5' of the cylinder 8 is connected with the screw hollow shaft 7 '. It is rotated at a slightly slower speed than the pulley (5), and a plurality of through holes (7 ") are drilled in the screw hollow shaft (7 ') and a plurality of sand barrel holes (8") in the front cone.

이상과 같이 구성된 본 고안은 분뇨속에 함유된 토사류를 분리 제가하는 장치인바 이를 사용할시는 여과기(1)에 분뇨를 투입하면 각종 협잡물은 여과기(1)내에 설치된 회전식 격차 장치에 의해 별도 수거되고, 이때 탈수된 액체(토사가 함유된 오니 현상)는 모터펌프(2)에 의해 사이크론(3)에 강제 유입되며, 이때의 유입상태는 사이크론(3)의 원통의 접선 수평방향으로 고속 유입되고, 유입된 액체는 원통 내벽을 따라 회전하게 되며 원추부에 이르게 되면 이때에는 회전 반경이 점차 작아지므로 "회전 모멘트 일정의 원리"에 의해 속도가 점차 빨라지면서 회전 하강을 계속한다.The present invention configured as described above is a device that separates the soil contained in the manure. When using this, when manure is put into the filter (1), various contaminants are collected separately by the rotary gap device installed in the filter (1). The dehydrated liquid (soil sludge phenomenon) is forcibly introduced into the cyclone 3 by the motor pump 2, and the inflow state is a high velocity flow in the tangential horizontal direction of the cylinder of the cyclone 3, The introduced liquid rotates along the inner wall of the cylinder, and when it reaches the cone, the radius of rotation becomes smaller at this time, so that the speed is gradually increased by the principle of "rotation moment constant" and the rotation continues to descend.

원추의 하단가까이 도달하면 이때에는 흐름이 반전 상승을 시작하여 사이크론(3)중심부를 따라 회전하면서 올라가 이송관(3')을 통해 본처리조(4)로 이송된다.When the lower end of the cone is reached at this time, the flow starts the reverse rise, rotates along the center of the cyclone 3 and ascends and is transferred to the main treatment tank 4 through the transfer pipe 3 '.

한편, 내벽에 접하여 회전 하강되어진 모래는 아직도 비중차에 의해 하부 배출구를 빠져 나와 이송관(3') 및 유입관(6')을 통하여 원심 분리기(6)로 유입된다. 원심 분리기로 유입되는 모래는 아직도 많은 양의 액체를 함유한 상태로서 중공축(7')에 뚫여있는 다수의 통공(7")을 통하여 실린더(8) 실내로 들어온다.On the other hand, the sand that has been rotated down in contact with the inner wall still exits the lower outlet by the specific gravity difference and is introduced into the centrifuge 6 through the transfer pipe (3 ') and the inlet pipe (6'). The sand entering the centrifuge still enters the cylinder 8 interior through a number of through holes 7 "bored in the hollow shaft 7 'in a state containing a large amount of liquid.

이와 같이 들어오면 실린더실(8)실내의 스크류(7)는 실린더(8)보다 빠른 속도로 회전하고 있음으로 유입된 액체와 모래 혼합액은 원심력 작용에 의해 실린더(8)의 내벽으로 모이게 되고, 이때 비중이 무거운 모래는 실린더 내벽에 밀접되어 원주방향으로 분산되어지고, 비중이 가벼운 물은 배수공(8')을 통해 밖으로 배출된다.In this way, the screw 7 in the cylinder chamber 8 rotates at a faster speed than the cylinder 8, so that the introduced liquid and sand mixture are collected on the inner wall of the cylinder 8 by centrifugal action. The heavy gravity sand is circumferentially distributed in close contact with the inner wall of the cylinder, and the light gravity gravity is discharged out through the drain hole 8 '.

즉, 실린더는 스크류보다 약간 감속되어 회전하고 있기 때문에 이와같은 회전차에 의해 실린더(8)내벽에 분산되어 있는 모래는 비교적 빠르게 회전되는 스크류 익편에 안내되어 배수공(8')과는 반대방향으로 빠져나온 과정, 원심력에 의해 자체가 함유하고 있는 물기가 거의 탈수되어진 후 배출공(8")으로 배출된 후 그 하부에 설치된 콘베어(9)에 의해 수거처리 된다.That is, since the cylinder is rotated slightly lower than the screw, the sand dispersed in the inner wall of the cylinder 8 is guided to the screw blade that is rotated relatively quickly by the rotation difference, and falls out in the opposite direction to the drain hole 8 '. The water contained in the process is almost dehydrated by the centrifugal force, and then discharged into the discharge hole 8 " and then collected by the conveyor 9 installed at the lower portion thereof.

이와 같이하여 처리된 양을 사이크론을 중심으로 하여 살펴보면 사이크론(3)으로 유입된 양을 1000ℓ 로 설정하면 이 가운데 약0.5%를 모래라고 볼 때 유입된 분뇨는 액체 995ℓ모래5ℓ로 나누어 진다.As described above, the treated amount is set in terms of the cyclone, and when the amount introduced into the cyclone (3) is set to 1000ℓ, when about 0.5% of this is regarded as sand, the manure introduced is divided into liquid 995ℓ and sand 5ℓ.

그리고 사이크론(3)하부에 배출되는 모래성분과 상부로 배출되는 액체의 비를 1 : 9로 하면(연속시 사이크론에서는 하부와 상부의 배출비를 1 : 4-1 : 20정도까지 조정할 수 있다.)사이크론(3)의 하부에는 모래성분100ℓ가 배출되며, 상부에는 액체 성분 900ℓ가 배출된다.모래는 거의 전부가 하부로 배출되므로 사이크론(3)의 하부에 배출되는 모래 성분 100ℓ는 액체 95ℓ와 모래5ℓ로 나누어진다.즉, 최초 모래 함량 0.5%의 분뇨가 사이크론을 거치는 동안 모래 함량 5%의 분뇨로 농축되는 결과가 된다.If the ratio of the sand component discharged to the lower part of the cyclone (3) and the liquid discharged to the upper part is 1: 9 (in the case of continuous cyclone, the discharge ratio of the lower part and the upper part can be adjusted to about 1: 4-1: 20). 100 l of sand component is discharged from the lower part of the cyclone 3, and 900 l of liquid component is discharged from the upper part. Since 100% of the sand is discharged to the lower part of the sand, 100 l of sand component discharged from the lower part of the cyclone 3 It is divided into 95 liters of liquid and 5 liters of sand, which means that manure with an initial sand content of 0.5% is concentrated to 5% sand with manure during the cyclone.

이 5%모래성분의 분뇨 100ℓ를 이번에는 원심분리기에 투입하여 여기에서는 모래성분 6.5ℓ와 액체성분 93.5ℓ의 분뇨로 분리해 낸다.모래성분 6.5ℓ는 모래 5ℓ와 액체 1.5ℓ의 혼합액으로 이는 수분 함량 약23%의 모래라 할수 있는데 수분 함량 23%의 모래는 손으로 쥐었을 때 손에 물기가 거의 묻어나지 않으며, 모래를 쌓아 놓았을 때 바닥에 물이 베어 나오지 않는 정도로서 모래 입자 사이에 접착력이 생긴 상태에 불과하므로 모래만을 거의 분리해 냈다고 볼수 있는 것이다.이상과 같이 본 고안은 여과기(1)에 의해 협잡물이 여과, 수거된 분뇨액을 사이크론(3)에서 약 90%수분을 미리 제거하고 남은 나머지 10%에 해당되는 모래와 액체의 혼합액을 원심 분리기(6)에 보내어 원심력 및 스크류(7)와 실린더(8)의 회전차에 의해 모래를 원심 분리할 수 있게 하였기 때문에 분뇨의 전처리 효율을 높일수 있는 것이다.This 100% manure of 5% sand is introduced into a centrifuge and separated into 6.5l of sand and 93.5l of liquid. This is a mixture of 5l of sand and 1.5l of liquid. It is about 23% sand, and the water with 23% moisture content hardly adheres to the hands when grasped by hand, and when sand is stacked, water does not come out on the floor. Only sand is almost separated, so it can be seen that the present invention. As described above, the present invention removes about 90% of the manure from the cyclone (3) by collecting the manure liquor filtered and collected by the filter (1). The remaining 10% of the liquid mixture of sand and liquid was sent to the centrifuge (6) to centrifuge the sand by centrifugal force and the rotational difference between the screw (7) and the cylinder (8). Which will in turn, benefits the pretreatment efficiency of manure at the door.
