한편, 상기 집수조는 바로옆에 침사조를 둘 수도 있는바, 상기 침사조는 집수조와 동일한 용기 개념이다.On the other hand, the sump tank may have a sedimentation tank next to the bar, the sedimentation tank is the same container concept as the sump.

그리고, 상기 집수조(10)에 공기를 제공하는 메인 배관(20)을 상기 집수조(10)의 상부면 일측에 고정설치하며, 상기 메인 배관(20)의 내부에는 중공홀이 형성되어 있기 때문에 외부 불로워에서 공급하는 공기를 중공홀을 통해 이송한다.In addition, the main pipe 20 for supplying air to the sump tank 10 is fixedly installed at one side of the upper surface of the sump tank 10, and since the hollow hole is formed in the main pipe 20, the external fire is not provided. The air supplied from the lower is transferred through the hollow hole.

실제로 상기 메인 배관(20)은 집수조(10)의 측면 일측부터 끝단까지 존재하게 되며, 일정한 각격마다 분배 파이프가 설치되어 있고, 상기 분배 파이프로 공기를 전달한다.In fact, the main pipe 20 is present from one side to the end of the collection tank 10, the distribution pipe is installed at regular intervals, and delivers air to the distribution pipe.

상기 제 1 분배 파이프(30)는 메인배관(20)의 일정간격마다 존재하며 수평하게 튀어나오도록 결합되어 공기압을 중계한다.The first distribution pipe 30 exists at regular intervals of the main pipe 20 and is coupled to protrude horizontally to relay air pressure.

상기 분배 파이프용 조절변(40)은 제 1 분배 파이프(30)의 끝단부에 연결되며, 수도꼭지와 같은 제어수단을 이용하여 제 1 분배 파이프로부터 출력되는 공기압을 조절토록 한다.The control valve 40 for the distribution pipe is connected to the end of the first distribution pipe 30 to adjust the air pressure output from the first distribution pipe using a control means such as a faucet.

상기 배관연결용 고압호스(50)는 유연성이 확보되어 자유롭게 상하로 유동가능하다.The high pressure hose 50 for pipe connection is secured flexibility and can be freely moved up and down.

또한, 상기 배관연결용 고압호스(50) 역시 내부에 중공홀이 형성되어 있기 때문에 제 1 분배 파이프(30)를 통해 입력되는 공기를 전송하는 역할을 한다.In addition, the high pressure hose 50 for pipe connection also serves to transmit the air input through the first distribution pipe 30 because the hollow hole is formed therein.

상기 제 2 분배 파이프(60)는 배관연결용 고압호스(50)에 연결되어 있으며, 자체 무게에 의해서 수직하게 집수조로 내려간 상태를 유지한다.The second distribution pipe 60 is connected to the high pressure hose 50 for pipe connection, and maintains the vertically down to the water collection tank by its own weight.

The configuration of the valve 50 and the control valve 40 enables stable operation by enabling mobility and preventing damage to the main supply air pipe so as to be free from clogging and easy access to a specific place.

이하에서 사용실시예를 통해 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail with reference to examples.

본 발명은 집수조(10) 상부에 메인배관(20)을 설치하여 필요한 수량의 제 1 분배파이프(30) 설치하고, 상기 제 1 분배 파이프(30)에는 배관 연결용 고압호스 (50)및 제 2 분배파이프(60)를 연결하여 구성하며, 제 1 분배 파이프(30)에는 조절변(50)을 설치하여 이루어지는바, 최초 에어를 분사하게 되면 불로워(70)로부터 제공되는 에어가 메인배관(20)을 거치게 되고, 이어 상기 메인배관(20)에 결합된 제 1 분배파이프(30)와 조절변(50)과 배관 연결용 고압호스(50) 및 제 2 분배 파이프(60)를 통해 집수조 하단에 에어를 공급하게 된다.The present invention installs the first distribution pipe 30 of the required amount by installing the main pipe 20 in the upper part of the sump tank 10, the high-pressure hose (50) and the second connection pipe for the first distribution pipe (30) The distribution pipe 60 is connected and configured, and the first distribution pipe 30 is formed by installing the control valve 50. When the first air is injected, the air provided from the blower 70 is the main pipe 20. And then, through the first distribution pipe 30 and the control valve 50 and the high pressure hose for connecting the pipe 50 and the second distribution pipe 60 coupled to the main pipe 20 at the bottom of the sump tank. To supply air.

따라서, 집수조(10)의 하단부를 통해 포기처리가 이루어지고, 이후 집수조 내부에서 시멘트의 응고가 발생되면 제 2 분배 파이프(60)를 건져내도록 한다.Therefore, the aeration process is made through the lower end of the sump (10), and if the solidification of cement in the sump is to take out the second distribution pipe (60).

그러면 제 2 분배 파이프(60)를 안전하게 이송시킬 수 있게 되고, 포크레인과 같은 작업도구로 집수조에 응결된 시멘트와 기타 불순물을 제거하게 되며, 이때에는 공기배관을 상부로 건져내어 작업하게 함으로써, 종래와는 달리 집수조 내부의 배관공작물이 파괴되는 것을 예방할 수 있다.Then, the second distribution pipe 60 can be safely transported, and the cement and other impurities condensed in the water collection tank are removed by a work tool such as a fork crane, and in this case, the air pipe is delivered to the upper part to work. Otherwise, the pipework inside the sump can be prevented from being destroyed.

즉, 종래에는 집수조의 바닥면에 배관을 설치하여 포기처리를 하기 때문에 시멘트와 같은 응고제가 응결될시에 포크레인등으로 불순물을 제거하면서 집수조의 바닥면에 설치된 분배파이프를 손상시킬 염려가 있었으나, 본 발명에서와 같이 자바라 형식의 배관 연결용 고압호스(50)를 통해 제 2 분배 파이프(60)를 설치하고 있으므로, 제 2 분배 파이프(60)를 쉽게 건져낼 수 있게 되어 다른 작업도구에 의한 분배 파이프의 파괴를 막을 수 있게 된다.That is, in the past, pipes were installed on the bottom of the sump to give up treatment, and when the coagulant such as cement was condensed, there was a risk of damaging the distribution pipe installed on the bottom of the sump while removing impurities with a fork lane. Since the second distribution pipe 60 is installed through the bellows-type high pressure hose 50 as in the present invention, the second distribution pipe 60 can be easily pulled out of the distribution pipe by another work tool. It can prevent destruction.

또한, 본 발명은 상기와 같이 안전하게 제 2 분배 파이프(60)를 분리하면서도 포기처리를 하는 성능에 있어서는 종래와 동일한 역할을 하게 된다.In addition, the present invention plays the same role as the conventional one in the performance of giving up while separating the second distribution pipe 60 safely as described above.

즉, 제 2 분배 파이프(60)를 다수개 설치하고 그 끝단부를 통해 에어를 분사하기 때문에 종래의 파이프 성능과 차이가 없으며, 또한 본 발명은 각 분배 파이프 에 조절변을 설치하여 원하는 압력으로 포기처리를 하므로 안전하게 장비를 운용할 수 있다.That is, since a plurality of second distribution pipes (60) are installed and air is injected through the ends thereof, there is no difference from conventional pipe performance, and the present invention provides a control valve to each distribution pipe to give up the desired pressure. You can safely operate the equipment.

상술한 바와 같이 본 발명은 전처리 포기의 중단없이 안정적 전처리 포기가 가능하도록 하였으며, 하부의 침적이 이루어진 특정부위에 전처리 포기를 실시하여 침전물을 제거함으로서 집수조의 유효용량을 확보할 뿐만 아니라, 원활한 폐수처리가 이루어지도록 한다.As described above, the present invention enables a stable pretreatment without aborting the pretreatment, and by removing the sediment by giving up the pretreatment to a specific portion of the lower deposition, as well as ensuring the effective capacity of the water collection tank, smooth wastewater treatment To be done.

비록 본 발명이 상기에서 언급한 바람직한 실시예와 관련하여 설명되어졌지만, 본 발명의 요지와 범위로부터 벗어남이 없이 다른 다양한 수정 및 변형이 가능할 것이다. 따라서, 첨부된 청구의 범위는 본 발명의 진정한 범위내에 속하는 그러한 수정 및 변형을 포함할 것이라고 여겨진다.Although the present invention has been described in connection with the above-mentioned preferred embodiments, various other modifications and variations may be made without departing from the spirit and scope of the invention.
