상기 선회유도로(116)는 대략 단면이 사각형인 돌출부가 상기 선회류반응조(114)의 내벽면에 부착된 상태로 나선형태로 꼬이도록 형성된 것이다. 즉, 상기 선회유도로(116)는 상기 선회류반응조(114) 내부를 유통하는 혼합수가 선회할 수 있도록 상기 선회류반응조(114)의 내벽면에 돌출되는 것으로써, 혼합수는 상기 선회류반응조(114)를 유통하면서 상기 선회유도로(116)와의 접촉을 통해 선회하게 된다. The turning induction path 116 is formed to be twisted in a spiral shape with a protrusion having a substantially rectangular cross section attached to an inner wall surface of the turning flow reaction tank 114. That is, the swirl flow path 116 is projected to the inner wall surface of the swirl flow reaction tank 114 so that the mixed water circulating inside the swirl flow reaction tank 114, the mixed water is the swirl flow reaction tank While passing through the 114, the vehicle turns through contact with the turning induction path 116.

상기 슬러지부상방지판(120)은 플레시블한 플라스틱재료로 이루어져서 상하로 변형이 가능하다. 따라서, 상기 슬러지부상방지판(120)이 하측으로 변형되어 상기 경사판(122)의 상단과 맞닿게 되면, 유체의 이동이 차단될 수 있다.The sludge injury prevention plate 120 is made of a flexible plastic material can be deformed up and down. Therefore, when the sludge injury prevention plate 120 is deformed downward to contact the upper end of the inclined plate 122, the movement of the fluid may be blocked.

이 때, 상기 슬러지부상방지판(120)은 비중 1의 재료로 제작되는 것이 유체 내에서 변형이 용이하다.At this time, the sludge injury prevention plate 120 is made of a material having a specific gravity 1 is easily deformed in the fluid.

상기 케이싱(102)의 상부 타측에는 유출포트(130)가 설치되고, 상기 케이싱(102)의 내벽면에는 상기 유출포트(130)와 연통되도록 월류부(132)가 설치된다.Outflow port 130 is installed on the other side of the upper casing 102, and the overflow portion 132 is installed on the inner wall surface of the casing 102 to communicate with the outflow port 130.

본 발명의 실시예에 따른 무동력 고효율 침전조(100)는 기본적으로 상술한 바와 같이 구성된다. 이하, 상기 무동력 고효율 침전조(100)의 작동모습을 설명한다.The non-motor high efficiency sedimentation tank 100 according to the embodiment of the present invention is basically configured as described above. Hereinafter, the operation of the non-power-efficient high efficiency sedimentation tank 100 will be described.

원수가 원수유입포트(104)를 통해 유입되면, 상기 약품혼화조(106)의 일측공간으로 공급된다.When raw water is introduced through the raw water inflow port 104, it is supplied to one side space of the chemical mixing tank 106.

상기 약품혼화조(106)로 공급된 원수에 상기 약품공급관(108)을 통해 공지의 응집용 약품을 공급한다. Through the medicine supply pipe 108 to supply the raw water supplied to the drug mixing tank 106, a known drug for flocculation.

이 때, 상기 혼합홈(110) 및 상기 분리벽(107)에 의해 상기 원수가 회전하면서 약품과 혼화되게 되고, 상기 약품과 혼합된 혼합수는 상기 분리벽(107)을 넘어서, 상기 약품혼화조(106)의 타측공간을 통해 상기 혼합수유입포트(112)를 거쳐 상기 선회류반응조(114)로 공급된다.At this time, the raw water is rotated and mixed with the drug by the mixing groove 110 and the dividing wall 107, and the mixed water mixed with the drug exceeds the dividing wall 107, the chemical mixing tank It is supplied to the swirl flow reaction tank 114 through the mixed water inflow port 112 through the other space of the 106.

상기 선회류반응조(114) 내에 유입된 혼합수는 상기 선회유도로(116)에 의해 선회하면서 응집이 일어나게 된다. 따라서, 이러한 선회류의 영향으로 상기 선회류반응조(114) 내에 혼합수의 체류시간도 길어지게 되고, 선회류에 의한 유체운동으로 인해 응집이 활발하게 일어날 수 있다.The mixed water introduced into the swirl flow reaction tank 114 is caused to aggregate while turning by the swirl flow path 116. Therefore, the residence time of the mixed water in the swirl flow reaction tank 114 is also long due to the influence of the swirl flow, and the flocculation may be actively caused by the fluid movement by the swirl flow.

상기 선회류반응조(114)의 하부에 도달하면 상기 디퓨저(118)에 의해 유속이 감소하면서 선회류가 멈추고 층류로 변환되면서 슬러지가 침강하기 시작한다.When reaching the lower portion of the swirl flow reaction tank 114, the flow rate is reduced by the diffuser 118, the swirl flow is stopped and converted to laminar flow, the sludge begins to settle.

따라서, 상기 침전부(101)에 슬러지가 쌓이게 되며, 슬러지가 분리된 물은 상측으로 이동한다. 이 때, 상기 경사판(122,124) 및 상기 슬러지부상방지판(120)에 의해 슬러지의 부상은 방지된다.Therefore, sludge is accumulated in the precipitation unit 101, and the water from which the sludge is separated moves upward. At this time, the sludge is prevented by the slant plate 122, 124 and the sludge injury prevention plate 120.

상기와 같은 작용으로 처리된 물은 상등하여, 상기 월류부(132)를 거쳐 유출포트(130)로 배출된다.The water treated by the above operation is the same, and is discharged to the outlet port 130 via the overflow portion 132.

따라서, 상기 무동력 고효율 침전조(100)는 동력없이 반응조, 응집조, 침전조의 모든 역할을 수행하게 된다.Therefore, the non-power-efficient high-efficiency settling tank 100 performs all the roles of the reaction tank, the coagulation tank, the precipitation tank without power.

그리고, 상기 슬러지배출구(126)를 통해 슬러지를 배출하는 경우에는 상기 침전부(101) 내부의 압력이 하강하게 되고, 이에 따라 상기 슬러지부상방지판(120) 이 하측으로 변위하여 상기 경사판(122)의 상단에 닿게 되어서 상기 침전부(101)가 폐쇄된다. 따라서, 이러한 작용으로 인해 슬러지의 벌킹현상을 억제할 수 있게 된다.When the sludge is discharged through the sludge discharge port 126, the pressure inside the sedimentation unit 101 is lowered. Accordingly, the sludge injury prevention plate 120 is displaced downward and thus the inclined plate 122. The precipitation portion 101 is closed by touching the top of the. Therefore, due to this action it is possible to suppress the bulking phenomenon of the sludge.
