도 2는 본 발명에 따른 상향류식 모래 여과기의 전체적인 구조를 나타낸 도면이고, 도 3은 본 발명에 따른 상향류식 모래 여과기의 유입관 부위를 확대한 상태의 도면이며, 도 4는 본 발명에 따른 상향류식 모래 여과기의 모래세정부를 확대한 상태의 도면이다.Figure 2 is a view showing the overall structure of the upflow sand filter in accordance with the present invention, Figure 3 is an enlarged view of the inlet pipe portion of the upflow sand filter in accordance with the present invention, Figure 4 is an upward view according to the present invention It is an enlarged state of the sand washing part of a flow type sand filter.
도시한 바와 같이 상향류식 모래여과기는 여과탱크(10), 디스트리뷰터(20), 세척수단(30), 에어리프트관(40), 세정수챔버(50), 세정수관(60), 모래세정부(70)로 구성되어 있다.As shown in the upflow sand filter, the filtration tank 10, the distributor 20, the washing means 30, the air lift pipe 40, the washing water chamber 50, the washing water pipe 60, the sand washing unit ( 70).
상기 여과탱크(10)는 내부에 모래여과층(11)이 형성되고, 상기 모래여과층(11)을 통과한 원수가 상측으로 이동되면서 오염물질이 제거된 후 처리수둑(12)에서 오버플로우 되어 배출되도록 처리수관(13)이 상부에 형성되어 있다.The filtration tank 10 has a sand filtration layer 11 formed therein, and the raw water passing through the sand filtration layer 11 is moved upward to remove contaminants and then overflows from the treated water tank 12. The treated water pipe 13 is formed at the top to be discharged.
상기 디스트리뷰터(20)는 유입관(21)을 통해 상기 여과탱크(10) 내부로 유입된 원수를 모래여과층(11)에 분사시키는 것이다.The distributor 20 sprays the raw water introduced into the filtration tank 10 through the inlet pipe 21 to the sand filtration layer 11.
상기 세척수단(30)은 상기 유입관(21)의 내부에 설치되어 유입되는 원수를 세척하는 것으로, 고압의 공기를 분사하도록 관(31)상에 노즐(32)을 복수개 설치하는 것이 바람직하다.The washing means 30 is installed in the inlet pipe 21 to wash the incoming raw water, it is preferable to install a plurality of nozzles 32 on the pipe 31 to inject high-pressure air.
즉, 상기 세척수단(30)에 의해 유입관(21)의 내부로 유입되는 원수에 고압의 공기를 분사하여 원수내에 포함되어져 있는 부유물질이 상기 여과탱크(10)의 내부에 모래에 엉키는 현상을 방지하도록 할 수 있다.That is, by blowing the high-pressure air to the raw water introduced into the inlet pipe 21 by the washing means 30, the floating material contained in the raw water is entangled in the sand inside the filtration tank 10. Can be prevented.
상기 에어리프트관(40)은 상기 여과탱크(10)에 수직으로 설치되고 공기 압축기(미도시)에서 공급되는 공기를 하측에 분사하여 오염된 모래를 상승시키도록 이중관 형태로 이루어져 있다.The air lift pipe 40 is vertically installed in the filtration tank 10 and consists of a double pipe shape to raise contaminated sand by spraying air supplied from an air compressor (not shown) to the lower side.
즉, 상기 에어리프트관(40)의 외통(41)으로 공기 압축기에서 공급되는 공기를 하측으로 분사하여 여과탱크(10)의 하방에 위치되어진 오염된 모래를 내통(42)으로 유입되도록 하는 것이다.That is, by spraying the air supplied from the air compressor to the outer cylinder 41 of the air lift pipe 40 to the lower side to allow the contaminated sand located below the filtration tank 10 to be introduced into the inner cylinder 42.
상기 세정수챔버(50)는 상기 에어리프트관(40)의 상단부에 설치되어져 상기 에어리프트관(40)을 통해 상승된 모래와 세정수가 모이게 되는 것이다.The washing water chamber 50 is installed at the upper end of the air lift pipe 40 is to collect the sand and the washing water raised through the air lift pipe (40).
상기 세정수관(60)은 상기 세정수챔버(50)에 모인 세정수를 배출하도록 일단은 상기 세정수챔버(50)에 연결되고, 타단은 외부와 연결되어진다.The washing water pipe 60 is connected to the washing water chamber 50 at one end thereof and connected to the outside to discharge the washing water collected in the washing water chamber 50.
상기 모래세정부(70)는 상기 세정수챔버(50)의 하방에 위치되어져 1차 세정된 모래를 하방으로 낙하시키면서 2차세정하도록 하는 지그재그형의 유로(71)가 형성되며, 상기 지그재그형 유로(71)는 상부보다는 하부의 외경이 넓게 이루어져 있다.The sand washing unit 70 is positioned below the washing water chamber 50 to form a zigzag flow passage 71 for secondary washing while dropping the first washed sand downward. 71 has a wider outer diameter than the upper portion.
상기와 같이 하부의 외경이 상부보다 넓게 형성되도록 하는 것은 하방에서 상승되는 처리수의 유입이 많게 하여 상부에서 낙하하는 모래의 속도를 저하시켜 세척시간을 증가하도록 하는 것이다.The outer diameter of the lower portion is formed to be wider than the upper portion as described above is to increase the washing time by increasing the inflow of the treated water rising from the lower side to lower the speed of the sand falling from the upper portion.
또한, 상기 모래세정부(70)는 종래와는 달리 금속재로 이루어지도록 하여 장시간 운전중도 에어리프트관(40)에서 이탈되지 않도록 한다.In addition, the sand washing unit 70 is made of a metal material unlike the prior art so as not to be separated from the air lift pipe 40 even during long time operation.
본 발명에 따른 작용을 상세히 설명하면 다음과 같다.Referring to the operation according to the invention in detail as follows.
본 발명에 따른 상향류식 모래 여과기는 유입관(21) 내에 설치된 세척수단(30)에서 분사되는 고압의 공기에 의해 원수에 함유된 부유물질이 과다 투입되어도 원활하게 모래여과층(11) 내에 설치되어진 디스트리뷰터(20)에 의해 모래여과층(11) 전역에 균일하게 분사되어 상승하게 된다.The upflow sand filter according to the present invention is smoothly installed in the sand filtration layer 11 even when an excessive amount of suspended solids contained in the raw water is injected by the high pressure air injected from the washing means 30 installed in the inlet pipe 21. The distributor 20 is uniformly sprayed and raised throughout the sand filtration layer 11.
상기 모래여과층(11)에 분사된 원수는 오래여과층(11)을 통과하면서 오염물질은 모래여과층(11)에 포집되고, 여과수는 모래여과층(11)의 상부로 이동하여 처리수둑(12)에서 오버플로우되어 처리수관(13)을 통해 외부로 배출된다.The raw water sprayed on the sand filtration layer 11 passes through the long filtration layer 11, and contaminants are collected in the sand filtration layer 11, and the filtered water moves to the top of the sand filtration layer 11 to treat the treated water basin ( Overflowed in 12) is discharged to the outside through the treated water pipe (13).
상기에서 원수를 여과해서 오탁한 물질을 포착한 오염된 모래는 여과탱크(10)의 하방에 위치되어지며, 이 오염된 모래는 에어리프트관(40)의 외통(41)을 통해 분사되는 압축공기에 의해 내통(42)을 통해 부상하면서 1차로 세정작업이 이루어진다.The contaminated sand, in which the raw water is filtered to capture the contaminated material, is located under the filtration tank 10, and the contaminated sand is compressed air injected through the outer cylinder 41 of the air lift pipe 40. As a result, the cleaning operation is primarily performed while floating through the inner cylinder 42.
상기 에어리프트관(40)을 통해 부상한 오염된 모래는 세정수챔버(50)에 도달하여서는 다시 하방의 모래세정부(70)의 지그재그형 유로(71)를 통해 하방으로 낙하하면서 2차로 세정작업이 이루어진다.The contaminated sand, which floats through the air lift pipe 40, reaches the washing water chamber 50, and is washed secondly while falling downward through the zigzag flow passage 71 of the sand washing unit 70 below. This is done.
이 과정에서 모래세정부(70)의 하부가 상부보다 면적이 넓게 이루어져 하방으로 부터 처리수의 유입이 많게 하여 상부에서 낙하하는 모래의 속도를 저하시켜 세척시간을 증가하도록 하여 세척효율을 향상시키는 것이다.In this process, the lower part of the sand cleaner 70 has a larger area than the upper part, thereby increasing the inflow of treated water from the lower side, thereby decreasing the speed of the sand falling from the upper part to increase the washing time, thereby improving the washing efficiency. .
또한, 상기 세정수챔버(50)에 유입된 세정수는 세정수관(60)을 통해 외부로 배출되어진다.In addition, the washing water introduced into the washing water chamber 50 is discharged to the outside through the washing water pipe (60).
