Description

폭기형 수중믹서{Aeration type submersible mixer}Aeration type submersible mixer

본 발명은 폭기형 수중믹서에 관한 것으로서, 좀더 상세하게는 수중에 설치되어 외부에서 공급되는 공기를 수중 내에서 물과 함께 효과적으로 폭기시켜 침전물처리 및 정화를 위한 수처리 시설에 유용하게 사용할 수 있도록 한 폭기형 수중믹서에 관한 것이다.
The present invention relates to an aeration type underwater mixer, and more particularly, it is installed in water to effectively aeration of water supplied from the outside with water in the water so that it can be effectively used in water treatment facilities for sediment treatment and purification It relates to a deformed underwater mixer.

일반적으로 수중펌프, 수중믹서, 수중교반기 등은 수중에 설치되어 유체를 흡입하여 강제 유동시키는 장치로서, 크게 그 구조를 살피면, 케이싱 내에 회전구동을 위한 모터가 설치되고, 모터의 회전축에 유체를 혼합, 혹은 강제 이송시키기 위한 임펠러가 설치된다. In general, a submersible pump, an underwater mixer, an agitator, etc. are installed in water to suck fluid and forcibly flow the fluid. When the structure is largely examined, a motor for rotating driving is installed in the casing, and the fluid is mixed in a rotating shaft of the motor. , Or impellers for forced transport are installed.

상술한 바와 같은 수중펌프, 수중믹서는 정수장과 같은 대규모 정화조를 갖춘 정화시설, 저수지, 폐수처리장 등과 같은 수처리 시설에 대폭 적용되어 운영되고 있으며, 수중에 공기를 투입하여 수중을 폭기시켜 용존산소량을 늘려 수질을 정화하거나, 각종 미생물 공급, 약품공급, 산소공급의 혼합으로서 수질을 정화하는데 이용되고 있다.Submersible pumps and water mixers are widely applied to water treatment facilities such as water purification plants, reservoirs, and wastewater treatment plants with large septic tanks such as water purification plants, and by adding air to the water, aeration of the water to increase dissolved oxygen. It is used to purify water quality, or to purify water quality as a mixture of various microorganism supply, medicine supply, and oxygen supply.

상기와 같이 공기의 공급은 수중에 설치된 수중 믹서에 공기 공급구를 외부에서 최대한 수중믹서의 임펠러측에 근접 설치하여 임펠러의 고속 회전으로 폭기시키고 있으나, 공기와의 혼합 정도가 수중믹서의 가동 대비 교반율이 매우 미비한 문제점이 있었다.As described above, the air supply is aerated in the underwater mixer installed in the water close to the impeller side of the underwater mixer as much as possible from the outside, and aerated by the high speed rotation of the impeller, but the degree of mixing with the air is less than the operation of the underwater mixer There was a problem of very low rate.

상기와 같이 교반 효율이 저조하게 나타남에 다라 수중믹서를 오랜 시간 구동시켜야 하고, 이에 따라 수중믹서의 사용은 전력소비가 높아지며, 수중믹서의 수명이 떨어지는 단점이 있었다. As the stirring efficiency is low as described above, it is necessary to drive the underwater mixer for a long time. Accordingly, the use of the underwater mixer has a disadvantage in that power consumption is increased and the life of the underwater mixer is reduced.

더욱이 심도가 있는 수처리 시설에서는 대기압에 따라 공기가 공급되는 구조와는 별도로 수중믹서의 임펠러 회전작용에 의한 교반이 균일하게 작용하지 않고 개별적으로 작용하는 예가 대부분으로 수중믹서의 교반 성능이 매우 낮아지는 폐단이 있어 특히 심도있는 장소에서의 수중믹서 사용이 불가한 점이 있었다.
In addition, in a deep water treatment facility, agitation by the impeller rotation of the submersible mixer does not work uniformly, apart from the structure in which air is supplied according to the atmospheric pressure. This makes it impossible to use underwater mixers, especially in deep places.

본 발명은 상기와 같이 제반되는 종래의 문제점을 해결하기 위하여 발명한 것으로서, 그 목적은 수중에 설치되어 외부에서 공급되는 공기를 수중 내에서 물과 함께 효과적으로 폭기시켜 침전물처리 및 정화를 위한 수처리 시설에 유용하게 사용할 수 있는 폭기형 수중믹서를 제공함에 있다.

상기 회전축이 관통된 케이싱의 후부에 외부로부터 공기공급관과 연결되는 공기유입구가 일측에 형성되고, 공기유입구와 통하는 내실을 갖는 공기공급케이스가 기밀설치되며, 상기 회전축은 공기공급케이스를 통한 공기를 통과시키기 위한 중공의 축으로 이루어지되, 일단부에 체결부를 두어 제공되는 너트로서 상기 임펠러의 중심결합공을 관통하여 연결설치된 것을 특징으로 한다.An air inlet connected to the air supply pipe from the outside is formed at one side of the casing through which the rotating shaft penetrates, and an air supply case having an inner chamber communicating with the air inlet is hermetically installed, and the rotating shaft passes air through the air supply case. It is made of a hollow shaft for the purpose, it is characterized in that the nut is provided by placing the fastening portion at one end is connected through the center coupling hole of the impeller.

본 발명에 따른 상기 회전축에 결합되는 임펠러의 중심결합공 일측에는 내측에서 외측으로 확장되어 구배지는 요홈부가 형성된 것을 특징으로 한다.

이하, 본 발명을 첨부된 도 1 내지 도 4를 참조하여 더욱 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to FIGS. 1 to 4.

본 발명은, 수중모터(10)의 케이싱(11)으로부터 메카니컬 실(12)로 회전가능하게 방수처리된 회전축(13) 일측에 임펠러(20)를 결합하여서 된 폭기형 수중믹서(100)에 있어서,The present invention, in the aeration-type underwater mixer 100 by combining the impeller 20 to one side of the rotating shaft 13 rotatably waterproof from the casing 11 of the submersible motor 10 to the mechanical seal 12 ,

상기 회전축(13)이 관통된 케이싱(11)의 후부에 외부로부터 공기공급관(H)과 연결되는 공기유입구(14a)가 일측에 형성되고, 공기유입구(14a)와 통하는 내실(14b)을 갖는 공기공급케이스(14)가 기밀설치된다.An air inlet 14a connected to the air supply pipe H from the outside is formed at one side of the rear side of the casing 11 through which the rotating shaft 13 penetrates, and the air has an inner chamber 14b communicating with the air inlet 14a. The supply case 14 is airtightly installed.

즉, 상기 내실(14b)의 위치는 회전축(13)의 후방에 위치되며, 상기 수중모터(10)의 케이스(11) 후방과 공기공급케이스(14) 사이에는 별도의 기밀패킹과 외부로부터 체결볼트 및 너트의 체결로서 기밀처리된다.That is, the position of the inner chamber 14b is located at the rear of the rotary shaft 13, and a separate airtight packing and a fastening bolt from the outside between the case 11 and the air supply case 14 of the submersible motor 10. And as the fastening of the nut.

상기 회전축(13)은 공기공급케이스(14)를 통한 공기를 통과시키기 위한 중공의 축으로 이루어지되, 일단부에 체결부(13a)를 두어 제공되는 너트(N)로서 상기 임펠러(20)의 중심결합공(21)을 관통하여 연결설치된다.The rotating shaft 13 is made of a hollow shaft for passing air through the air supply case 14, the center of the impeller 20 as a nut (N) provided by having a fastening portion (13a) at one end It is connected through the coupling hole 21 is installed.

상기 회전축(13)에 결합되는 임펠러(20)의 중심결합공(21) 일측에는 내측에서 외측으로 확장되어 구배지는 요홈부(22)가 형성되어 기포발생이 임펠러의 중앙 내측에서 외측으로 퍼져나가는 형태로 발생하도록 한다. One side of the center coupling hole 21 of the impeller 20 coupled to the rotation shaft 13 is formed with a groove portion 22 extending from the inner side to the outer side to form a bubble so that bubble generation spreads from the inner side of the impeller to the outer side. To occur.

상기와 같이 구성된 본 발명인 수중믹서(100)는 수중에 설치되며, 공기공급관(H)을 통해 외부에서 공기는 별도로 공급시켜 줄 수 있는 상태에서 작동이 이루어진다.Underwater mixer 100 of the present invention configured as described above is installed in the water, the operation is made in a state that can be supplied separately from the air through the air supply pipe (H).

상기와 같은 작동은 수중믹서(100)의 제일 핵심부인 수중모터(10)를 구동하고, 이에 따른 임펠러(20)의 고속회전에서 수중에서 기포의 다량발생과 더불어 효과적으로 폭기시켜줄 수 있게 된다.The operation as described above can drive the underwater motor 10, which is the core of the underwater mixer 100, thereby effectively aeration with a large amount of bubbles in the water at high speed rotation of the impeller 20.

상기 공기공급관(H)측에는 외부에 설치된 밸브(도면에서 생략함)의 제어에 따라 그 공급되는 양을 조절할 수 있으며, 공기공급케이스의 공기유입구(14a)를 따라 그 내실(14b)에 공기가 유입되고, 중공으로 된 회전축(13)을 통하여 임펠러(20)가 결합된 요홈부(22)의 중앙에서 공기를 배출시킨다.The air supply pipe (H) side can be adjusted according to the control of the valve (not shown in the figure) installed on the outside, the air flows into the inner chamber (14b) along the air inlet (14a) of the air supply case The air is discharged from the center of the recess 22 to which the impeller 20 is coupled through the hollow rotating shaft 13.

이때 배출되는 공기는 회전하는 임펠러에 의해 공기방울이 보다 미세하게 부수어지면서 수중 산소량을 늘려준다.At this time, the discharged air increases the amount of oxygen in the water while the air bubbles are broken more finely by the rotating impeller.

즉, 산소가 희박한 수중상태를 효과적으로 공기방울을 임펠러의 회전력으로 폭기되도록 하여 풍부한 상태로 산소량을 늘려줌으로써 특히 오염된 물을 정수시키는 정화시설과 같은 장소에서의 수중믹서 사용은 침전물과의 일정한 믹싱으로 정화효과를 상승시킬 수 있게 된다.In other words, the use of an underwater mixer in a place such as a purification facility that cleans contaminated water by increasing the amount of oxygen in a rich state by effectively aeration of the air bubbles with the impeller's rotational force in an underwater state where oxygen is scarce is necessary. It can increase the purification effect.

본 발명에 따른 중공의 회전축을 통해 임펠러 중앙에서 배출되어 수중을 폭기하도록 한 수중믹서는 비교적 3미터 내지 5미터 정도로 심도가 양수장 등에서도 공기배출 압력 조정과 임펠러의 회전속도를 맞추어 효과적으로 폭기시킬 수 있어 대규모 정화시설, 폐수처리장, 배수펌프장 등지에 적합하게 운영할 수 있는 이점이 있다.
The underwater mixer, which is discharged from the center of the impeller through the hollow rotating shaft according to the present invention to aeration in the water, can be effectively aerated by adjusting the air discharge pressure and the rotational speed of the impeller even at a depth of about 3 m to 5 m. There is an advantage that can be appropriately operated in large-scale purification facilities, wastewater treatment plants, drainage pumping stations.
