Abstract

The present invention relates to an underwater aeration apparatus for treating livestock excrement. An outlet port of an air suction pipe (26) interposed between an air supply hose (24) and an air storage chamber (20) is positioned in a suction chamber (28) of an underwater pump (12). Accordingly, air is suctioned when the underwater pump (12) pumps the livestock excrement. Accordingly, the air mixed in the livestock excrement pumped passes through the underwater pump (12) such that oxygen is primarily dissolved. The livestock excrement having the primarily dissolved oxygen passes through a nozzle (18) of a primary eruption tube (22) and is erupted into a second eruption pipe (36). In this procedure, oxygen is secondarily dissolved. Livestock excrement having the secondarily dissolved oxygen is tertiarily dissolved while passing through a screw (32) of the second eruption pipe (36). The livestock excrement, which has oxygen tertiarily dissolved, passes through the nozzle (34) of the secondary eruption pipe (36), and is erupted underwater in the state that rotational force and diffusion force given by the screw (32) are added to strong ejection pressure given by the nozzle, such that oxygen is quaternarily dissolved. Accordingly, the aeration efficiency may be significantly increased.

본 발명의 목적은 축산분뇨저장조내 축산분뇨를 펌핑하여 수중에 분출하기까지 산소의 집중적인 용해가 수차례 반복되게 할 수 있고 또 주위 침전물이나 부유물에 대한 호기성 미생물들의 활동을 더욱 촉진시켜줄 수가 있는 축산분뇨 처리를 위한 수중 폭기장치를 제공하는데 있다.It is an object of the present invention to pump livestock manure in a livestock manure storage tank so that the intensive dissolution of oxygen can be repeated several times until it is ejected into the water, and further promote the activity of aerobic microorganisms on surrounding sediments or suspended matter. It is to provide an underwater aeration device for manure treatment.

상기한 목적달성을 위한 본 발명 축산분뇨 처리를 위한 수중 폭기장치는 공기공급호스와 공기저장실을 사이에 두고 있는 공기흡입관의 출구가 수중펌프의 흡입실에 위치하도록 하여 수중펌프가 축산분뇨를 펌핑할시 공기의 흡입이 동시에 이루어져 펌핑된 축산분뇨에 혼입된 상태로 수중펌프를 통과하면서 산소의 1차용해가 이루어지도록 하고, 산소가 1차용해된 축산분뇨는 1차분출관의 노즐을 통과하여 2차분출관에 분출되는 과정에서 산소의 2차용해가 이루어지도록 하고, 산소가 2차용해된 축산분뇨는 2차분출관의 유입관내 스크류를 통과하면서 산소의 3차용해가 이루어지도록 하며, 산소가 3차용해된 축산분뇨는 2차분출관의 노즐을 통과하여 노즐에 의해 주어진 강한 분출압에 스크류에 의해 주어진 회전력과 확산력이 더해진 상태로 수중에 분출되면서 산소의 4차용해가 이루어지도록 구성함을 특징으로 한다.In the underwater aeration device for the treatment of livestock manure according to the present invention for achieving the above object, the outlet of the air suction pipe interposed between the air supply hose and the air storage chamber is located in the suction chamber of the submersible pump, so that the submersible pump can pump livestock manure. At the same time, air is sucked at the same time so that the primary dissolution of oxygen is achieved while passing through the submersible pump in a state mixed with the pumped livestock manure, and the livestock manure with the primary dissolution of oxygen passes through the nozzle of the primary discharge pipe and into the second discharge pipe. In the process of ejection, secondary dissolution of oxygen occurs, and livestock manure in which oxygen is secondary dissolved passes through the screw in the inlet pipe of the secondary ejection pipe so that the third dissolution of oxygen occurs, and the livestock manure in which oxygen is third dissolved is secondary. It is characterized in that it is configured so that the fourth dissolution of oxygen is made by being ejected into the water in a state in which the rotational force and diffusion force given by the screw are added to the strong ejection pressure given by the nozzle through the nozzle of the outlet pipe.

본 발명은 수중펌프(12) 펌핑작동시 흡입실(28)에서 작용하는 강한 흡입력에 의해 폭기에 필요한 충분한 량의 외부공기가 흡입되어 축산분뇨에 혼입된 상태로 임펠러의 강한 회전력이 주어지는 수중펌프(12)의 펌핑실(40)과 노즐(18)을 갖는 1차분출관(22) 및 스크류(32)와 노즐(34)을 갖는 2차분출관(36)을 차례로 통과하여 수중에 분출되기까지 4차에 걸친 미립자화로 산소의 용해가 이루어지게 되므로 폭기효율을 현저히 높여줄 수 있어 액비생산기간을 단축시켜줄 수 있고 또 폭기효율이 높아진 만큼 폭기장치의 용량이나 필요대수를 줄여줄 수 있어 설치비용 및 운용비용을 절감할 수 있게 된다.The present invention is a submersible pump 12, in which a sufficient amount of external air required for aeration is sucked by a strong suction force acting in the suction chamber 28 during the pumping operation and mixed into livestock manure, and a strong rotational force of the impeller is given ( It passes through the primary ejection pipe 22 with the pumping chamber 40 and the nozzle 18 of 12) and the secondary ejection pipe 36 with the screw 32 and the nozzle 34 in sequence until it is ejected into water. Since oxygen is dissolved through microparticles over a period of time, the aeration efficiency can be remarkably increased, which can shorten the liquid manure production period. Also, as the aeration efficiency has increased, the capacity or required number of aeration devices can be reduced. Can be saved.

또한 2차분출관(36)을 통과하여 수중에 분출되는 축산분뇨는 노즐(34)에 의한 강한 분출압에 스크류(32)에 의한 회전력과 확산력이 더해지면서 주위의 침전물과 부유물까지도 부상시켜서 호기성 미생물들의 활동을 촉진시켜주게 되므로 액비생산기간을 더욱 단축시켜줄 수가 있게 된다.In addition, livestock manure ejected into the water after passing through the secondary ejection pipe 36 increases the rotational force and diffusion force by the screw 32 to the strong ejection pressure by the nozzle 34, causing the surrounding sediments and suspended matter to float, thereby preventing aerobic microorganisms. Since it promotes the activity, it is possible to further shorten the liquid manure production period.

그리고 수중펌프(12)의 흡입실(28)에서 흡입된 공기가 축산분뇨에 혼입된 상태로 수중펌프(12)와 1차분출관(22) 및 2차분출관(36)을 차례로 통과하면서 4차에 걸친 미립자화로 대부분의 산소가 축산분뇨에 용해되게 할 시 기포발생량이 현저히 줄어들게 되므로 용해되지 못한 산소로 인한 거품발생의 최소화할 수 있어 축산분뇨저장조의 주위환경을 깨끗이 유지할 수 있고 또 거품제거용 펌프를 없애주는데 따른 금전적 이익까지도 기대할 수가 있게 된다.And, while the air sucked from the suction chamber 28 of the submersible pump 12 is mixed in the livestock manure, it passes through the submersible pump 12, the primary ejection pipe 22 and the secondary ejection pipe 36 in order, When most of the oxygen is dissolved in the livestock manure through microparticles, the amount of air bubbles is significantly reduced.Therefore, the generation of bubbles due to undissolved oxygen can be minimized, so that the surrounding environment of the livestock manure storage tank can be kept clean, and a pump for removing bubbles is installed. You can expect even the financial benefits of getting rid of it.

In addition, as the rotational force and diffusion force by the screw 32 are added to the strong ejection pressure by the nozzle 34, the surrounding sediment and floating matter are also floated, and the activity of aerobic microorganisms on the surrounding livestock manure is further enhanced. Will facilitate.

즉, 본 발명에 이용되는 수중펌프(12)를 가장 널리 이용되고 있는 2마력으로 기준하여볼 때, 펌핑작동시 축산분뇨가 약50mm의 내경을 갖는 흡입실(28)을 약6,8m/sec의 강하고 빠른유속으로 통과하면서 1분당 약0.8톤의 펌핑능률을 발휘하게 되므로 그 흡입실(28)에 약10mm 내경의 공기흡입관(26)이 위치하도록 할 경우 상기 공기흡입관(26)에도 강한 흡입력이 작용하면서 외부로부터 1분당 약15~20L의 공기가 흡입되고 또 흡입된 공기는 곧바로 펌핑된 축산분뇨에 혼입되어 펌핑실(40)을 통과할 시 고속회전하는 임펠러에 의해 미립자화되면서 산소의 1차용해가 이루어지게 된다.That is, based on the water pump 12 used in the present invention based on the most widely used 2 horsepower, the suction chamber 28 having an inner diameter of about 50 mm when the livestock manure is pumped is about 6,8 m/sec. As the air intake pipe 26 with an inner diameter of about 10 mm is located in the suction chamber 28, a strong suction force is also applied to the air intake pipe 26 as it passes at a strong and fast flow rate of about 0.8 ton per minute. As it acts, about 15~20L of air is sucked per minute from the outside, and the sucked air is immediately mixed into the pumped livestock manure, and when it passes through the pumping chamber 40, it becomes particulate by the impeller rotating at high speed, and the primary dissolution of oxygen. Will come true.

또한 수중펌프(12)를 통과하면서 산소가 1차용해된 축산분뇨는 수중펌프(12)의 배출관(14)에 연결된 1차분출관(22)을 통과하면서 출구가 좁은 노즐(18)에 의해 가압력이 주어진 상태에서 2차분출관(36)내에 분출될 시 축산분뇨에 혼입되어 있는 공기가 미립자화 되면서 산소의 2차용해가 이루어지게 된다.In addition, the livestock manure in which oxygen is first dissolved while passing through the submersible pump 12 passes through the primary discharge pipe 22 connected to the discharge pipe 14 of the submersible pump 12, and a pressing force is given by the nozzle 18 with a narrow outlet. When ejected into the secondary ejection pipe 36 in the state, the air mixed in the livestock manure becomes particulate and secondary dissolution of oxygen occurs.

또한 1차분출관(22)을 통과하면서 산소가 2차용해된 축산분뇨는 2차분출관(36)의 유입관(30) 내측후방에 갖는 스크류(32)의 통과시 주어지는 가압력과 회전력에 의해 축산분뇨에 혼입되어 있는 공기가 미립자화 되면서 산소의 3차용해가 이루어지게 된다.In addition, livestock manure in which oxygen is secondly dissolved while passing through the primary outlet pipe 22 is prevented by the pressing force and rotational force applied when the screw 32 inside the inlet pipe 30 of the secondary outlet pipe 36 passes. As the mixed air becomes particulate, the tertiary dissolution of oxygen occurs.

그리고 2차분출관(36)의 스크류(32)를 통과하면서 산소가 3차용해된 축산분뇨는 곧바로 출구가 좁은 노즐(34)을 통과하면서 강한 가압력이 주어지고 또 노즐(34)을 통과하여 스크류(32)에 의해 주어진 회전력을 갖고 수중에 분출될 시 축산분뇨에 혼입되어 있는 공기가 미립자화 되면서 산소의 4차용해가 이루어지게 된다.And the livestock manure in which oxygen is thirdly dissolved while passing through the screw 32 of the secondary ejection pipe 36 immediately passes through the nozzle 34 with a narrow outlet, and a strong pressing force is applied, and passes through the nozzle 34 and passes through the screw 32 When ejected into the water with the rotational force given by ), the air mixed in the livestock manure becomes particulate and the fourth dissolution of oxygen occurs.

더 나아가 2차분출관(36)을 통과하여 수중에 분출되는 축산분뇨는 노즐(34)에 의해 주어지는 강한 분출압에 스크류(32)에 의해 주어지는 회전력과 확산력이 더해지면서 주위의 침전물과 부유물을 부상시켜서 이들에 대한 호기성 미생물들의 활동을 더욱 촉진시켜주게 되므로 액비생산기간을 더욱 단축시켜줄 수 있게 된다.Furthermore, the livestock manure ejected into the water through the secondary ejection pipe 36 floats the surrounding sediments and suspended solids as the rotational force and diffusion force given by the screw 32 are added to the strong ejection pressure given by the nozzle 34. Since the activity of aerobic microorganisms against them is further promoted, the production period of liquid manure can be further shortened.
