Description

원통형의 메쉬스크린과 헬리컬바를 이용한 고액분리장치 {Solid-liquid separation apparatus using cylindrical mesh screen and helical bar}Solid-liquid separation apparatus using cylindrical mesh screen and helical bar}

본 발명은 오폐수 및 하수를 처리하기 위한 고액분리장치에 관한 것으로서, 보다 구체적으로는 원통형의 메쉬스크린의 내부에 나선형의 바(bar)를 설치하여 고형물과 여액을 효율적으로 분리시키기 위한 고액분리장치에 관한 것이다.The present invention relates to a solid-liquid separator for treating wastewater and sewage, and more particularly, to a solid-liquid separator for efficiently separating solids and filtrates by installing a spiral bar inside a cylindrical mesh screen. It is about.

각종 생활오수, 하수 및 축산폐수, 산업폐수, 고농도 유기성 폐수를 처리하는데 있어 유입수에 포함되어 있는 각종 부유물, 고형물 및 협잡물을 일차적으로 분리 제거시킴으로써 후단의 처리과정이 원활하게 진행될 수 있도록 하는데, 이같은 역할을 수행해 주는 장치로서 고액분리장치가 이용된다.In the treatment of various domestic sewage, sewage and livestock waste, industrial waste, and high concentration organic wastewater, the various processes such as floatation, solids, and contaminants contained in influent are separated and removed, so that the latter process can be carried out smoothly. Solid-liquid separation apparatus is used as a device for performing this.

이와 같은 장치로는 메쉬스크린, 시브스크린, 드럼스크린 등이 있는데, 이들 장치는 유입수의 성상 및 사용목적에 따라 구분되어 사용된다.Such devices include mesh screens, sheave screens, drum screens, and the like, which are used according to the characteristics of the influent and the purpose of use.

상기 장치들은 유입수에 포함되어 있는 각종 부유물질과 고형물, 협잡물들을 분리 제거시키게 되는데, 스크린망을 통과한 여액은 다음 공정으로 흘러 들어가고 스크린망에 걸린 이들 여과물들은 그대로 남겨지거나 유출구를 통해 빠져나가게 된다. 스크린망에 걸린 여과물들은 다량의 수분을 함유하고 있으며 그로 인해 고형물 의 형태를 유지할 수 없어 콘베이어벨트 등을 통해 이송을 할 때 흘러 내리는 현상이 있고, 그 부피 또한 커질 수 밖에 없다.The devices separate and remove various suspended solids, solids and contaminants contained in the influent. The filtrate through the screening network flows into the next process and these filtrates which remain on the screening network are left intact or exit through the outlet. The filtrate caught on the screen net contains a large amount of water, and as a result, it cannot maintain the solid form, so that it may flow down when conveying through a conveyor belt, etc., and the volume thereof may also increase.

또한 반복적인 여과물의 제거 및 여액의 통과로 인해 스크린망의 간극이 폐색되는 현상이 발생될 뿐만 아니라, 이로 인해 전체적인 기능이 저하되는 문제점이 있었다.In addition, due to repeated removal of the filtrate and passage of the filtrate, not only the phenomenon in which the screen net gap is occluded, but also the overall function is reduced.

이러한 문제점으로 인해 스크린망을 자주 청소해주어야 함에 따라 시간도 많이 소요되고 작업효율도 저하되어 사용상의 불편함 뿐만 아니라 후처리공정에도 영향을 주는 단점도 있었다.Due to these problems, screen screens need to be cleaned frequently, which takes a lot of time and reduces work efficiency, which has disadvantages in terms of post-processing as well as inconvenience in use.

또한, 상기 메쉬스크린 표면의 일부 또는 전체에는 일정한 간격의 간극이 구비된다.In addition, some or all of the surface of the mesh screen is provided with a gap at regular intervals.

이와 같이 구성된 본 발명의 작용은 다음과 같다.The operation of the present invention configured as described above is as follows.

메쉬스크린(2) 등을 둘러싸고 있는 몸체(12)와 이를 지지해주는 지지후레임이 있고, 원수인 오폐수 및 하수가 유입배관(1)을 통해 몸체(12)안으로 유입되면 내부의 헤더(9)에서 원수가 배분되어 메쉬스크린(2) 위로 떨어지게 되고, 전원이 인가되어 구동모터(7)가 회전하게 되면 그 회전축상에 있는 구동바퀴(8)가 회전되어 원통형의 메쉬스크린(2)에 회전력을 전달함으로써 헬리컬바(13)가 부착되어 있는 메쉬스크린(2)이 일정한 속도로 회전하게 된다. There is a body 12 surrounding the mesh screen 2 and the like and a supporting frame for supporting the same. When waste water and sewage, which are raw water, are introduced into the body 12 through an inflow pipe 1, raw water is contained in the header 9 inside. Is distributed over the mesh screen 2, and when the power is applied and the driving motor 7 rotates, the driving wheel 8 on the rotation axis is rotated to transmit rotational force to the cylindrical mesh screen 2 by The mesh screen 2 to which the helical bar 13 is attached is rotated at a constant speed.

헤더(9)를 통해 메쉬스크린(2) 위로 떨어진 원수중 고형물과 협잡물은 스크린에 여과되어 남겨지고 메쉬스크린의 간극을 통해 빠져나간 여액은 몸체(12)의 하부에 집수되어 유출배관(6)을 통해 배출되어 후처리공정으로 이송되게 된다.Solids and contaminants in raw water dropped over the mesh screen (2) through the header (9) are filtered out on the screen and the filtrate drawn out through the gap of the mesh screen is collected in the lower part of the body (12) to drain the outflow pipe (6). It is discharged through and transferred to the aftertreatment process.

원통형의 메쉬스크린(2)은 전체가 미세한 간극을 갖고 있어 액체는 그 간극을 통해 빠져 나가게 되고 액체가 빠져나간 원수중의 슬러지는 회전하고 있는 메쉬스크린(2)에 의해 원심력이 발생됨으로써 슬러지에 부착되어 있는 수분과의 분리가 일어나게 되며, 메쉬스크린 내부에 일정한 간격으로 상하로 설치된 헬리컬바(13)에 의해 슬러지배출부(14)쪽으로 이송이 된다.The cylindrical mesh screen (2) has a fine gap in its entirety, and the liquid is drawn out through the gap, and the sludge in the raw water from which the liquid escapes is attached to the sludge by the centrifugal force generated by the rotating mesh screen (2). Separation with the moisture is generated, it is transported toward the sludge discharge unit 14 by the helical bar 13 installed up and down at regular intervals in the mesh screen.

도 3의 상세도는 메쉬스크린(2)의 내부에 설치된 헬리컬바(13)를 설명하는 것인데, 이 헬리컬바(13)는 메쉬스크린(2)과 일정한 간격을 유지하면서 같은 방향으로 상하로 설치되어 있어 회전하면서 슬러지를 슬러지배출부(14)쪽으로 밀어내게 된다.  The detailed view of FIG. 3 illustrates a helical bar 13 installed inside the mesh screen 2, which is installed vertically in the same direction while maintaining a constant distance from the mesh screen 2. As it rotates, the sludge is pushed toward the sludge discharge unit 14.

슬러지의 진행방향으로 나선구조를 갖는 헬리컬바(13)는 메쉬스크린(2)에 여과된 슬러지를 회전방향과 같은 방향으로 이송시키게 되는데, 이 과정에서 슬러지는 메쉬스크린(2)과 함께 회전을 하게 되며, 동시에 헬리컬바(13)의 나선구조를 따라 슬러지가 다시 트위스트되는데, 일정한 간격으로 상하로 설치되어 있는 헬리컬바(13)를 따라 이러한 연속적이고 반복적인 회전을 거치면서 슬러지에 함유되어 있 는 수분의 탈수가 이루어져 함수율이 적은 고형물의 형태를 갖게 되며, 함수율이 높은 상태의 흘러내리는 현상을 방지할 수 있다.The helical bar 13 having a spiral structure in the direction of the sludge transfers the sludge filtered on the mesh screen 2 in the same direction as the rotation direction. In this process, the sludge rotates together with the mesh screen 2. At the same time, the sludge is twisted again along the helical structure of the helical bar 13, and the water contained in the sludge is subjected to such continuous and repeated rotation along the helical bar 13 installed up and down at regular intervals. Dehydration of the to form a solid having a low moisture content, it is possible to prevent the phenomenon of high water content flowing down.

그리고 이러한 계속되는 고액분리과정에서 메쉬스크린의 간극에 이물질이 붙게 되어 이를 제거해줄 필요가 있는데, 이런 현상을 방지하기 위해 주기적으로 세척장치(3)가 작동된다. In this continuous solid-liquid separation process, foreign matter is attached to the gap of the mesh screen and needs to be removed. To prevent this phenomenon, the cleaning device 3 is periodically operated.

몸체(12)의 하부에 모여진 여액을 이용하여 세척펌프(5)가 작동되면 세척장치(3)를 통해 세척수가 이송되기 시작하며, 세척장치(3)의 말단부를 따라 설치된 노즐(4)을 통해 메쉬스크린(2)의 상부로 세척수가 분사되어 간극에 붙어 있는 이물질을 제거해주게 되는데, 이러한 세척과정은 주기적으로 이루어져 메쉬스크린(2)의 간극이 폐색되는 현상을 방지하여 준다.When the washing pump 5 is operated by using the filtrate collected in the lower part of the body 12, the washing water is started to be transferred through the washing apparatus 3, and through the nozzle 4 installed along the distal end of the washing apparatus 3. The washing water is sprayed to the upper portion of the mesh screen 2 to remove foreign substances adhering to the gap. This washing process is periodically performed to prevent the gap of the mesh screen 2 from being blocked.
