상기 흡입관(10)은 강이나 정수장 및 하수처리장의 골재 및 모래를 용이하게 흡입하도록 외주연에 금속링(11)과 로프(13)가 설치되는 것으로, 도 1에 도시된 바와 같이 수면 아래에서 잠수부가 물속에 들어가서 흡입관(10)을 상기 로프(13)를 잠수부가 잡은 상태로 자유롭게 이동시키면서 물과 함께 골재 및 모래를 준설할 수 있게 되고, 상기 흡입관(10)의 외주연에 설치된 금속링(11)으로 인해 상기 흡입관(10)이 수면으로 떠오르지 않게 된다. The suction pipe 10 is a metal ring 11 and the rope 13 is installed on the outer periphery so as to easily suck the aggregate and sand of the river or water purification plant and sewage treatment plant, as shown in FIG. It is possible to dredge aggregate and sand together with water while freely moving the suction pipe 10 while the rope 13 is caught by the diver in the water, and the metal ring 11 installed at the outer circumference of the suction pipe 10. Due to the suction pipe 10 does not rise to the surface.

그리고, 상기 샌드펌프(20)는 상기 흡입관(10)의 타측에 연결되어 물밑 골재 및 모래를 물과 함께 퍼 올리도록 하는 것이다. In addition, the sand pump 20 is connected to the other side of the suction pipe 10 to pump up the submerged aggregate and sand together with water.

즉, 상기 샌드펌프(20)를 구동시키면 물밑에서 잠수부가 상기 흡입관(10)을 이동시키면서 골재 및 모래를 물과 함께 펌핑하게 된다. That is, when the sand pump 20 is driven, the submersible pumps aggregate and sand together with water while moving the suction pipe 10 under the water.

또한, 상기 세척부(30)는 상기 샌드펌프(20)에 이동관(35)을 매개로 연결되어 물과 함께 퍼 올려진 골재 및 모래를 세척한다. In addition, the washing unit 30 is connected to the sand pump 20 via a moving pipe 35 to wash the aggregates and sand raised with water.

여기서, 상기 세척부(30)는, 금속으로 제조되고 내주연에 나선형 돌출편(32)이 형성된 중공형 몸체(31)와, 상기 에어 콤푸레셔(40)에서 상기 몸체(31)의 내측으로 공급되는 압축공기의 양을 조절하는 공기조절밸브(33)와, 상기 이동관(35)과 유동관(55)에 연결을 원활히 하기 위한 연결소켓(34)으로 구성되고, 상기 에어 콤푸레셔(40)는 상기 세척부(30)에 에어관(45)을 매개로 연결되어 상기 세척부(30)로 압축공기를 공급하게 된다. Here, the washing part 30 is made of a metal and the hollow body 31 formed with a spiral protrusion 32 on the inner circumference, and is supplied to the inside of the body 31 from the air compressor 40 It consists of an air control valve 33 for adjusting the amount of compressed air, and a connecting socket 34 for smoothly connecting the moving pipe 35 and the flow pipe 55, the air compressor 40 is the washing unit The air pipe 45 is connected to the 30 to supply compressed air to the washing unit 30.

다시 말해, 상기 몸체(31)의 일측단과 타측단에 상기 연결소켓(34)이 구성되어 있어 상기 이동관(35)과 유동관(55)을 연결하는 상태로 설치되고, 상기 세척부(30)를 교체시 원활히 교체할 수 있게 된다. In other words, the connection socket 34 is configured at one end and the other end of the body 31 so as to connect the moving tube 35 and the flow tube 55 to replace the washing unit 30. It can be replaced smoothly.

또한, 상기 몸체(31)에 나선형 돌출편(32)이 형성되어 있어 골재 및 모래가 물과 함께 상기 세척부(30)의 몸체(31)내측으로 인입되어 나선형으로 회전되면서 세척됨과 동시에 상기 에어 콤푸레셔(40)로부터 공급되는 압축공기에 의해 세척효율이 향상된 상태로 상기 유동관(55)으로 배출된다. In addition, a spiral protrusion 32 is formed on the body 31 so that aggregate and sand are introduced into the body 31 of the washing unit 30 together with water to be helically rotated and washed, and at the same time the air compressor. Compressed air supplied from 40 is discharged to the flow pipe 55 in a state where the washing efficiency is improved.

한편, 상기 선별기(50)는 상기 세척부(30)에 유동관(55)을 매개로 연결되어 상기 세척부(30)에서 세척된 골재 및 모래를 선별하게 된다. On the other hand, the sorter 50 is connected to the washing unit 30 through the flow pipe 55 to sort the aggregate and sand washed in the washing unit 30.

여기서, 상기 선별기(50)는 상기 유동관(55)으로부터 배출되는 골재 및 모래 를 집수하는 집수칸(51)과 상기 집수칸(51)에서 유출되는 골재 및 모래를 크기별로 선별하는 선별칸(52)이 구성되어 있고, 상기 선별칸(52)의 하측에는 상기 선별칸(52)에서 선별된 골재 및 모래를 저장하기 위한 저장칸(53)이 별도로 구성되어 있다. Here, the sorting unit 50 is a collecting compartment 51 for collecting aggregate and sand discharged from the flow pipe 55 and a sorting compartment 52 for selecting aggregate and sand flowing out of the collecting compartment 51 by size. Is configured, the storage compartment 53 for storing the aggregate and the sand selected by the sorting compartment 52, the lower side of the sorting compartment 52 is configured separately.

이와 같이 샌드펌프와 에어 콤푸레셔를 이용하여 샌드펌프에서 물과 함께 흡입된 골재 및 모래를 상기 샌드펌프의 구동에 의한 와류현상과 에어 콤푸레셔에서 공급되는 고압의 공기로 골재 및 모래를 효율적으로 세척하고, 선별기로 보내 선별하도록 함으로써 골재 및 모래등과 같은 여과사를 깨끗한 상태로 재활용할 수 있게 된다. As such, the aggregate and sand sucked together with the water from the sand pump using the sand pump and the air compressor are used to efficiently wash the aggregate and the sand by the vortex phenomenon driven by the sand pump and the high pressure air supplied from the air compressor. By sending it to the sorter to sort the filter sand such as aggregate and sand can be recycled in a clean state.

한편, 도 5는 본 발명에 따른 여과사 세척장치를 이용한 처리방법을 나타낸 블록도이다. On the other hand, Figure 5 is a block diagram showing a treatment method using a filter sand washing apparatus according to the present invention.

상기 도 5에 도시된 바와 같이, 본 발명에 따른 여과사 세척장치를 이용한 처리방법은 삽입단계와, 흡입단계, 세척단계, 선별단계로 구성된다. As shown in FIG. 5, the treatment method using the filter sand washing apparatus according to the present invention includes an insertion step, a suction step, a washing step, and a sorting step.

상기 삽입단계는 일측 외주연에 금속링(11)과 로프(13)가 설치된 흡입관(10)을 강이나 정수장 및 하수처리장의 물속에 삽입하는 것이다. The insertion step is to insert the suction pipe 10, the metal ring 11 and the rope 13 is installed on one side of the outer periphery in the water of the river or water purification plant and sewage treatment plant.

이후, 상기 흡입관(10)에 연결된 샌드펌프(20)를 작동하여 골재 및 모래를 흡입하여 세척부(30)로 이동시킨다. Then, by operating the sand pump 20 connected to the suction pipe 10 to suck the aggregate and sand to move to the washing unit 30.

다시 말해, 상기 샌드펌프(20)가 작동되면 물밑의 잠수부가 상기 흡입관(10)의 일측을 이동시키면서 골재 및 모래가 물과 함께 펌핑되어 상기 세척부(30)로 이동된다. In other words, when the sand pump 20 is operated, the aggregate and sand are pumped together with the water while the submerged portion moves under one side of the suction pipe 10 and is moved to the washing unit 30.

이때, 상기 세척부(30)로 펌핑된 골재 및 모래가 상기 세척부(30)의 내측에 형성된 나선형 돌출편(32)을 타고 이동되고, 이동되는 골재 및 모래에 고압의 공기가 분출되어 골재 및 모래가 더욱 효율적으로 세척된다. At this time, the aggregate and sand pumped to the washing unit 30 is moved aboard the spiral protrusion pieces 32 formed inside the washing unit 30, the high pressure air is ejected to the aggregate and sand to be moved aggregate and The sand is washed more efficiently.

그리고, 상기 세척단계를 거친 골재 및 모래는 유동관(55)를 통해 선별기(50)로 이동되어 크기별로 선별된다. Then, the aggregate and the sand that has undergone the washing step are moved to the sorter 50 through the flow pipe 55 to be sorted by size.

이와 같이, 세척기로 공급된 골재 및 모래와 같은 여과사를 더욱 효율적으로 세척하여 선별기를 통해 선별함으로써 더욱 깨끗한 상태로 여과사를 재활용할 수 있게 된다. As such, the filter sand such as aggregate and sand supplied to the washing machine may be more efficiently washed, and the filter sand may be recycled in a cleaner state by selecting through a sorting machine.

상기와 같이 본 발명에 관해 상세히 설명하였으나, 본 발명이 속하는 분야에 통상의 지식을 갖는 자라면 본 발명의 범주에서 벗어나지 않는 범위에서 다양한 변형실시가 가능할 것이다. 그러므로, 본 발명의 범위는 상술한 실시예에 한정하지 않고, 후술하는 특허등록범위뿐만 아니라, 이 청구범위와 균등한 것들에 의해 정해져야 할 것이다.
