본 고안은 연립식 급속여과지의 원수거로부터 공급되는 원수를 각 여과지로 균등하게 분배하는 유량균등 분배장치에 관한 것으로, 특히 원수거에서 여과지로 공급되는 원수가 원수거의 상측벽과 여과지의 측벽 상단에 걸쳐 설치되는 상향류 방식의 웨어구조물에 의해 균등 분배되게한 급속여과지의 유량 균등 분배장치에 관한 것이다.The present invention relates to an equal flow distribution device for evenly distributing the raw water supplied from the raw water collection of the simultaneous rapid filter paper to each filter paper, in particular, the raw water supplied to the filter paper from the raw water collection and the upper side wall of the filter paper The present invention relates to a uniform flow distribution device for rapid filter paper, which is distributed evenly by the upflow type wear structure installed over.

일반적으로 다수의 여과지를 병렬로 설치한 연립식 정압 급속여과지에 있어서는 원수주관 또는 원수주거로부터 각 여과지로 공급되는 원수를 균등 분배하기 위해 유량계를 설치하여 분배유량을 측정하고 원수변의 개도(度)를 조절하는 방식과, 본 고안 출원인이 선출원하여 실용신안등록 제29027호로 등록받은 바 있는 "유량자동 조절을 겸한 원수유입 및 억세척수 배출장치"에서 알려진 바와같이 원수의 등분배를 위한 원통형 웨어를 원수거의 하부벽에 설치하고 승강식 제수변을 이용하여 웨어를 개폐하는 방법등이 있다.In general, in a positive pressure rapid filter paper in which a plurality of filter papers are installed in parallel, a flow meter is installed to evenly distribute the raw water supplied to each filter paper from the raw water pipe or the raw water housing, and the flow rate is measured to measure the flow rate of the raw water. And a cylindrical wear for equal distribution of raw water, as known in the "Law water inflow and flushing water discharge device combined with automatic flow control", which was filed by the applicant of the present invention and registered under Utility Model Registration No. 29027. Is installed on the lower wall of the raw collection and the opening and closing of the wear using a lifting type dividing side.

그러나, 상기와 같은 종래의 유량 분배방법은 원수변 또는 제수변을 수리하거나 교체시에 전체 여과지의 가동을 일시 중지하지 않으면 많되는 폐단이 있으며, 후기의 웨어를 이용한 원수 분배방식에 있어서는 그 웨어가 차지하는 높이가 높아 원수거의 전체 용적이 축소될 뿐만아니라 웨어를 통해 지내로 도입되는 원수가 웨어의 상단을 넘어 들어가 하향식으로 공급되는 것이므로 웨어를 통한 공기의 흡입이 심하여 여과사의 유출이 발생되고 그 웨어의 상부에서 수직방향으로 개폐되는 평저변 즉, 저수변의 개방시 진공상태가 해소되면서 심한 소음이 발생되는 등의 문제점이 있었다.However, the conventional flow distribution method as described above has many closures when the operation of the entire filter paper is not paused at the time of repair or replacement of the raw water side or the fresh water side, and the water occupies the raw water distribution method using the late weir. As the height is high, not only the total volume of raw waste collection is reduced, but also the raw water introduced into the ground through the ware enters the top of the ware and is supplied from top to bottom. There was a problem such that a severe noise is generated when the vacuum is released when the flat bottom, ie, the bottom, is opened and closed in the vertical direction from the top.

따라서, 본 고안의 주목적은 상기와 같은 제반단점과 문제점들을 갖지 않는 급속여과지의 유량 균등 분배장치를 제공함에 있다.Therefore, the main object of the present invention is to provide a uniform flow rate distribution device for rapid filter paper without the above-mentioned disadvantages and problems.

본 고안의 다른 목적은 원수거의 원수를 지내로 균등분배 공급하는 상향류식 웨어 구조물을 원수거의 상측에 설치하여 원수거의 원수가 원통형 웨어의 하부에서 상부로 통과한후 지내에 공급되게 함으로써, 원수의 균등한 분배는 물론 원수의 공급과 차단을 위한 제수변의 밸브시트 기능을 갖게 하고 웨어구조물의 시공 설치가 용이할 뿐만 아니라, 평저변의 수리나 교체시에도 해당 여과지의 정상운전에 지장을 주지 않으며 타여과지의 정상운전이 가능한 급속여과지의 유량 균등 분배장치를 제공함에 있다.Another object of the present invention is to install an upflow ware structure that distributes the raw water of the raw water evenly into the base to the upper side of the raw collection so that the raw water of the raw waste passes from the bottom of the cylindrical ware to the top and then is supplied into the base, It not only distributes raw water but also has the function of valve seat of water valve for supply and blocking of raw water, and it is easy to install and install the wear structure, and it does not interfere with normal operation of the filter paper when repairing or replacing flat bottom. In addition, the present invention provides an equal flow distribution device for rapid filter paper capable of normal operation of other filter papers.

상기 수로구조물(10)은 일면이 트여진 U자형 측판(11)이 상기 저판(12)의 상단 주연에 일체로 형성되어 있어 그 측판(11)의 개방측 단부(11a)가 여과지(1)의 일측벽(1a)에 지지 고정되고 그 U자형 측판(11)의 상단부가 여과지(1)의 일측벽(1a)상단 및 원수거(2)의 상측벽(2a)상면과 일치되도록 고정 설치되며, 상기 저판(12)은 상기 측판(11)의 개방측단부(11a)에 위치하는 저판(12)의 일단이 그 반대측 단부보다 약간 낮은 위치에 놓이도록 소정 경사도를 갖는다.The channel structure 10 has a U-shaped side plate 11 having one surface formed integrally with the upper periphery of the bottom plate 12 so that the open end 11a of the side plate 11 is formed of the filter paper 1. It is supported and fixed to one side wall (1a) and the upper end of the U-shaped side plate 11 is fixedly installed so as to coincide with the upper side of the one side wall (1a) of the filter paper 1 and the upper side wall (2a) of the raw water collection (2), The bottom plate 12 has a predetermined inclination such that one end of the bottom plate 12 located at the open side end portion 11a of the side plate 11 is placed at a position slightly lower than the opposite end portion thereof.

상기한 수로구조물(10)의 중앙부에 설치되는 원통형 웨어(20)는 일정높이를 가지는 웨어(20)의 하단이 수로구조물(10)의 경사저판(12)에 형성된 통공(12a)과 일치되도록 수직 방향으로 용착 고정되어 있고 그 저판(12)의 상부로 돌출설치된 웨어(20)의 상단이 원수거(2)내부의 수위(WL)보다 소정폭만큼 낮은쪽에 위치하도록 배치되어 있으며, 이와같이 설치된 원통형 웨어(20)의 외주벽과 수로구조물(10)의 측판(11)사이에는 웨어(20)를 넘쳐 흐르는 원수가 여과지(1)내에 유입되게 하는 U자형 수로(C)가 형성된다.The cylindrical ware 20 installed at the central portion of the waterway structure 10 is vertical so that the lower end of the waterway 20 having a predetermined height coincides with the through hole 12a formed in the inclined bottom plate 12 of the waterway structure 10. And the upper end of the ware 20 which is fixed in the welding direction and protrudes to the upper part of the bottom plate 12 is located at a lower side by a predetermined width than the water level WL in the original collection 2, and the cylindrical ware installed as described above. Between the outer circumferential wall of (20) and the side plate (11) of the waterway structure (10), a U-shaped channel (C) is formed so that raw water flowing over the weir (20) flows into the filter paper (1).

또한, 상기와 같이 구성된 수로구조물(10)의 상부에는 평편상 커버판(30)이 원수거(2)의 상측벽(2a)과 같은 높이로 복개되어 있고 그 커버판(30)의 중앙하부 및 상부에는 상기 웨어(20)의 상단을 개폐하는 평저변(40)및 그 구동용 공압실린더(41)가 각각 설치되어 있다.In addition, the flat cover plate 30 is covered with the same height as the upper wall 2a of the original collection 2 on the upper portion of the channel structure 10 configured as described above, and the center lower portion of the cover plate 30 and In the upper portion, a flat bottom side 40 for opening and closing the upper end of the wear 20 and a driving pneumatic cylinder 41 are respectively provided.

도면중 미설명 부호 5는 급속여과지(1)의 여과층이고, 6은 압력실, 7은 정수거를 각각 보인 것이다.In the figure, reference numeral 5 denotes a filtration layer of the rapid filtration paper 1, 6 denotes a pressure chamber, and 7 denotes a water purifier.

이상과 같이 구성된 본 고안 장치의 작용효과를 다음과 같다.Effects of the present invention configured as described above are as follows.

상기 제4도는 평저변(40) 이 개방되어 원수거(2)의 원수가 여과지(1)로 공급되는 상태를 보인 것으로. 이와같은 상태에서는 원수거(2)내의 수위(WL)가 수로구조물(10)의 저판(12) 및 그 중앙부에 설치된 웨어(20)의 상단보다 높은 위치에 있으므로 원수거(2)의 원수는 웨어(20)의 하부에서 상부로 유입된 후 그 웨어(20)의 상단을 넘어 수로구조물(10)의 저판(12)상면으로 유출되고 이어 측판(11)의 개방측 단부(11a)를 통해 여과지(1)의 집수실(3)로 낙하된 후 분배관(4)을 통해 지내에 공급된다. 따라서 상기와 같은 상향유출식 웨어(20)를 넘어 공급되는 일류(溢流)수위 즉, 웨어(20)의 상류측 수위(WL')는 원수거(2)의 수위(WL)와 상시 동일하게 유지되므로, 각 여과지(1)에 설치되는 웨어(20)의 길이 및 그 설치높이를 동일하게 함으로써 병렬로 배치되는 각여과지에 공급되는 원수의 유량을 균등하게 분배할수 있게 되는 것이다.Figure 4 shows that the flat bottom side 40 is opened to feed the raw water of the raw water collection (2) to the filter paper (1). In this state, since the water level WL in the original collection 2 is at a position higher than the upper end of the bottom plate 12 of the waterway structure 10 and the ware 20 provided at the center thereof, the raw water of the original collection 2 is ware. After flowing from the lower part of the upper part 20 to the upper part of the bottom plate 12 of the water channel structure 10 beyond the upper end of the wear 20, and then through the open end 11a of the side plate 11, the filter paper ( After dropping into the collecting chamber 3 of 1), it is supplied into the ground through the distribution pipe 4. Therefore, the first-class water level supplied above the upflow weir 20, that is, the upstream water level WL ′ of the weir 20, is always the same as the water level WL of the original collection 2. Since it is maintained, the flow rate of the raw water supplied to each filter paper arranged in parallel can be equally distributed by making the length and the installation height of the wear 20 installed in each filter paper 1 the same.

또한, 상기와 같이 구성된 본 고안 장치에 있어서는 그 웨어(20)를 통해 공급되는 원수가 상향 유출된후 여과지(1)의 내부로 공급되는 것이므로 종래의 하향식 웨어를 통한 원수공급시와 같은 공기의 흡입현상과 이로인한 여과사의 유출 현상등이 발생되지 않으며, 웨어(20) 및 수로구조물(10)의 설치 부위가 원수거(2)의 상단부에 위치하게 됨에 따라 원수거의 하측벽에 설치되는 종래의 하향식 웨어에 비해 웨어(20)의 전체 높이를 낮출수 있게 되므로 원수거의 내부 용적을 충분히 활용할수 있게 된다.In addition, in the device of the present invention configured as described above, since the raw water supplied through the wear 20 is discharged upward and then supplied to the inside of the filter paper 1, intake of air as in the supply of raw water through the conventional top-down wear The phenomenon and the outflow phenomenon of the filter sand caused by this, and the installation site of the weir 20 and the water channel structure 10 is located in the upper end of the original collection (2) is a conventional installation on the lower wall of the original collection Compared to the top-down ware it is possible to lower the overall height of the ware 20 can fully utilize the internal volume of the original collection.

한편, 상기와 같은 평저변(40)의 개방 상태에서 원수의 공급을 중단하기 위해 제4도에 가상선으로 도시된 바와같이, 평저변(40)을 하강시켜 웨어(20)의 상단을 폐쇄하게 되면, 웨어(20)내부의 수위가 원수거(2)의 수위(WL)보다 낮은 위치 즉, 웨어(20)의 상단에 위치하게 되므로, 그 웨어(20)의 내부에는 진공 현상이 전혀 발생되지 않게 되고 이에따라 평저변의 재개방시에도 진공이 해소될때 발생되는 소음등은 전혀 발생되지 않게되는 것이다.On the other hand, in order to stop the supply of raw water in the open state of the flat bottom 40 as described above as shown in the virtual line in Figure 4, the flat bottom 40 is lowered to close the top of the wear 20 When the water level inside the weir 20 is lower than the water level WL of the raw collection 2, that is, at the top of the weir 20, no vacuum phenomenon is generated inside the weir 20. Accordingly, even when the flat bottom is reopened, noise generated when the vacuum is released is not generated at all.

이상에서 설명한 바와같이 본 고안은 연립식 여과지의 일측에 배치된 원수거의 원수를 각 단위여과지에 분배하는 웨어를 설치함에 있어서, 원수거의 상측벽과 여과지의 일측벽 상부에 걸쳐 그 원수거의 수위보다 낮은 높이에 배치되는 상향류식 웨어구조물을 설치하여 여과지로 공급되는 원수가 상향 유출된 후 지내에 공급되게한 것이므로, 웨어구조물의 시공 설치가 용이하고 평저변의 수리 또는 교체시에도 해당여과지는 물론 타여과지의 정상 운전이 가능하게 될뿐아니라, 연립식 여과지의 원수거 일측에 배치되는 각 웨어의 설치 높이(표고)를 동일하게 함으로써 각 단위 여과지로 유입되는 원수의 유량을 균등하게 분배할수 있으며, 평저변의 개방에 따른 소음 발생우려 및 원수의 공급에 따른 여과재의 유출 현상등을 배제할수 있게 되는 효과가 있다.As described above, the present invention provides a ware for distributing the raw water of the raw waste disposed on one side of the coalescing filter paper to each unit filter paper, and the raw waste collection over the upper wall of the raw waste collection and the upper side wall of the filter paper. Since the upstream type ware structure is installed at a level lower than the water level, the raw water supplied to the filter paper is discharged upward and then supplied to the ground. Therefore, the construction of the ware structure is easy to install, and the filter can be used even when repairing or replacing the flat bottom. Of course, not only the normal operation of other filter papers is possible, but also the flow rate of raw water flowing into each unit filter paper can be evenly distributed by setting the same height (altitude) of each ware arranged on one side of the raw water collection system of the system. , The possibility of noise generation due to the opening of the flat bottom and the outflow of the filter media due to the supply of raw water have.
