In this process, many chemicals are used, and a large amount of waste is required due to the generation of sludge containing chemicals. It is a reality

종래 경우 돈분뇨 처리의 다른 방법으로는 에어를 주입하여 미세한 기포를 물속에 존재시킨 상태에서 응집제를 투입하여 응집시키는데 이 과정에서 기포의 발생이 지나쳐 악취가 발생하고 분혼입된 거품이 대량 발생하는 문제가 있다Conventionally, in the case of the conventional method of treatment of pig manure, coagulation is performed by injecting a coagulant in a state where fine bubbles are present in water by injecting air. There is

본 발명은 상기한 문제를 해결하기 위하여 발명된 것으로, 돈분뇨에 부유하는 작은 고형물이 포함된 뇨 액상물을 공기를 주입시켜 이 공기를 잘게 쪼개는 임페라를 통과시켜 생성된 미세기포를 이용하여 돈분뇨 중의 고형물입자를 둘러싸게하여 공기와 함께 상부로 부상시켜 처리하는 방법을 제공한다. The present invention has been invented to solve the above problems, by injecting air into the urine liquid material containing a small solid suspended in the manure manure pig manure using fine bubbles generated by passing through the impeller to split the air finely It provides a method of enclosing the solid particles in the air and floating to the top with air to treat.

본 발명의 주요 구성은, 상부는 상커버(2)로 막혀지고 그 중 일부는 개방된 개방부(4)를 형성하는 가압부상실(1)과, 상기 가압부상실(1)의 개방부(4) 상부에 설치되어 전후 이동하는 스크래퍼(5)와, 상기 가압부상실(1) 내부에 설치되는 회전축(7)을 갖는 임펠러(8)와, 임펠러(8)를 회전 가동시키는 모터(9)와, 상기한 임펠러(8) 주변에 설치되어 에어를 불어 넣는 에어공급장치를 포함하는 것을 특징으로 하며, 상기한 에어공급장치는, 회전축(7)의 내부가 공동으로 형성되며, 그 회전축(7) 외주가 통공(11)이 형성되어, 이 통공(11)을 통하여 에어가 배출되게 구성한 것을 특징으로 하며, 상기한 에어공급장치는, 블로워(21)와, 이와 연결되며 외주에는 배출공(23)이 형성된 송급관(20)으로 구성되어, 임펠러(8) 주변에 설치하는 것을 특징으로 하며, 상기한 스크래퍼(5)는 이송롤러(15)를 갖춘 이송장치(6)에 설치되어, 이송장치(6)의 작동에 의하여 개방부(4) 상부에서 전후진 이동하는 것을 특징으로 한다

이하, 본 발명을 첨부 도면에 의거 추가로 상술한다Hereinafter, the present invention will be further described based on the accompanying drawings.

먼저, 도 1 은 본 발명에 따른 가압부상실을 예시한다First, Figure 1 illustrates the pressure loss in accordance with the present invention

가압부상실(1)에는 예를들어, 돈분 혼합물을 전처리로 고형물을 분리한 후, 액상의 뇨폐수가 주류를 이룬다. 이러한 뇨폐수에는 다량의 분 고형물이 혼합되어 있다. 이 미세한 분고형물을 일괄적으로 깨끗이 제거하기에는 매우 어려운 문제이다The pressurized inlet chamber 1, for example, after separating the solids by pretreatment of the pig meal mixture, the liquid urine wastewater is the mainstream. This urine wastewater contains a large amount of powdered solids. It is very difficult to remove all these finely divided solids in a batch.

따라서 본 발명에서는 도시한 바와 같이, 가압부상실(1) 내부에 임펠러(8)가 달린 회전축(7)이 설치되어 모터(9)의 작동으로 회전한다. 그리고 회전축(7)은 파이프 형상으로 그 내부에 공동이 형성되어 있다Therefore, in the present invention, as shown in the figure, the rotating shaft 7 with the impeller 8 is installed inside the pressure inlet chamber 1 to rotate by the operation of the motor 9. And the rotating shaft 7 is a pipe shape, the cavity is formed in the inside.

도 3 에서 보듯이, 회전축 외주에 통공(11)이 다수 형성되어 이 통공(11)을 통하여 에어가 분사되어 나온다. 이는 폐수 내에서 공기 방울을 만들어 내고 임펠러(8)는 고속으로 교반 회전하면서 그 발생된 큰 공기 방울을 파쇄한다. 그러면 미세한 공기 방울로 쪼개어 진다. 그 미세한 공기방울 기포(3)는 폐수 내의 뇨 속에 함유되어 있는 분이나 이물질 등의 무거운 부유물들을 감싸서 상부로 부상시킨다. 그리하여 폐수 내의 고형물들을 액상물로부터 분리하여 낸다As shown in FIG. 3, a plurality of through holes 11 are formed on the outer circumference of the rotating shaft, and air is ejected through the through holes 11. This produces air bubbles in the waste water and the impeller 8 stirs at high speed to break up the generated large air bubbles. This breaks up into fine air bubbles. The fine air bubble (3) is wrapped in the heavy suspended solids such as dust and foreign matter contained in the urine in the waste water to rise to the top. Thus, the solids in the wastewater are separated from the liquids

아울러 이 공급되는 에어는 액상의 폐수 내에 용해되어 용존산소의 농도를 높여 줌으로써 호기성 미생물을 성장하게 해 주는 환경을 제공한다In addition, the supplied air is dissolved in the liquid wastewater to increase the concentration of dissolved oxygen to provide an environment for growing aerobic microorganisms.

가압부상실(1)의 상부는 상커버(2)로 막혀 있고 일부는 개방부(4)로 구성되어 개방되어 있다. 그리고 개방부(4) 바로 위에는 스크래퍼(5)가 전후진하게 구성된다. 스크래퍼(5)가 전,후진하면 개방부(4) 위로 부상되는 축분 부유물이나 이물질 등의 고상 부유물들을 걷어냄과 아울러 기포(3)를 터뜨려 고상물만 분리하여 낼 수 있다. 상기 스크래퍼(5)의 전후진은 이송장치(6)에 의하여 전후진된다The upper part of the pressurizing part chamber 1 is closed by the upper cover 2, and a part is made up of the opening part 4, and is open. The scraper 5 is configured to be moved back and forth directly on the opening 4. When the scraper 5 is moved forward and backward, the solids floating, such as the suspended solids and foreign matter floating on the opening (4) can be removed, and the bubble 3 can be blown to separate only the solids. The forward and backward movement of the scraper 5 is advanced back and forth by the transfer device (6).

도 2 는 도 1 의 도면을 상면에서 본 도면이다FIG. 2 is a view of the drawing of FIG. 1 seen from above. FIG.

도시한 바와 같이, 가압부상실(1)을 상부에서 보면, 개방부(4)가 길게 형성되고 내부에는 폐수가 유입 및 유출되도록 흐르고 있다. 선택적으로 액상 폐수가 흐르지 않고 정류된 상태에서 처리할 수도 있음은 물론이다. 대량 처리시에는 천천히 흐르도록 하면서 처리하여도 좋다As shown in the figure, when the pressurization part chamber 1 is seen from above, the opening part 4 is formed long and the waste water flows in and out of the inside. Alternatively, the liquid wastewater may be treated in a rectified state without flowing. In the case of mass processing, you may process, making it flow slowly.

상면은 개방부(4)를 제외하고는 막혀 있어 개방부(4)로 올라오는 기포(3) 덩어리 들을 스크래퍼(5)가 개방부(4) 길이 방향으로 전후진하면서 기포(3)를 한곳으로 쓸어 모아둔다. 모아둔 기포는 별도의 룸에 투입되게 구성하여 그 내부에서 기포가 전부 제거되고 고형물만 남도록 하여도 된다The upper surface is blocked except for the opening portion 4, so that the bubbles (3) agglomerates rising to the opening portion (4) move the bubble (3) in one place while the scraper (5) moves forward and backward in the longitudinal direction of the opening portion (4). Sweep it up. Collected bubbles may be put in a separate room so that all bubbles are removed and only solids remain inside.

기포가 터지고 고형물만 모아지게 되면 이들을 별도로 다른 가축분 고형물과 함께 퇴비화하여 처리하면 된다. 예를들어 디켄터에서 나오는 분고형물과 함께 퇴비화할 수 있다
If the bubbles burst and only solids are collected, they can be composted separately with other livestock solids. For example, it can be composted with the solids from the decanter.

한편, 가압부상실(1)을 상면에서 보면 모터(9)가 상부에 형성되어 있고 모터(9)에 의한 고속 회전으로 내부가 빈 회전축(7)이 회전 교반된다. 도 1 에서 임펠러(8)를 2개 또는 그 이상 구성시키는데 그 이유는 기포(3)가 더 잘 쪼개어지게 하기 위한 것이다
On the other hand, when the pressurization part chamber 1 is seen from above, the motor 9 is formed on the upper part, and the rotating shaft 7 with an empty inside is rotated and stirred by the high speed rotation by the motor 9. In FIG. 1 two or more impellers 8 are configured to allow the bubbles 3 to split better.

도 4 는 본 발명의 또 다른 구성이다4 is another configuration of the present invention

본 실시 예에서는 회전축(7)에 통공(11)을 형성하지 않고 공기도 불어 넣치 않는다. 단, 별도의 배출공(23)이 다수 형성된 파이프 형상의 송급관(20)과 블로워(21)를 설치하여 임펠러(8)와 접촉하지 않는 근접한 위치에서 에어를 공급한다. 이와 같은 구성으로 하여도 배출공(23)을 통하여 나오는 기포(3)의 분쇄 효과는 동일하다In this embodiment, the through hole 11 is not formed in the rotation shaft 7 and air is not blown. However, by installing the pipe-shaped supply pipe 20 and the blower 21 in which a plurality of separate discharge holes 23 are formed, the air is supplied at a close position not in contact with the impeller 8. Even in such a configuration, the grinding effect of the bubble 3 coming out through the discharge hole 23 is the same.

단, 이 경우는 공기 송급관(20)이 회전하는 임펠러(8)에 방해를 주지 않게 하기 위하여 임펠러(8)는 1단으로 하며, 모터와 임펠러(8)의 전동 회전 기어비를 조정하여 임펠러(8)의 회전수를 모터회전수의 2배인 약 3600RPM으로 올려줌으로서 2단 임펠러의 효율과 거의 비슷한 수준으로 유지할 수 있다.In this case, however, in order to prevent the air supply pipe 20 from interfering with the rotating impeller 8, the impeller 8 is one-stage, and the impeller (by adjusting the electric rotary gear ratio of the motor and the impeller 8) is adjusted. By increasing the rotation speed of 8) to about 3600 RPM, which is twice the speed of the motor, it can be maintained at about the same level as the efficiency of the two-stage impeller.

그 외 임펠러를 사용함과 함께 공기를 유입시켜 부유물을 부상시키는 본 발명의 기술사상을 이용하여 여러 다른 형태의 구조로 만들어 낼 수 있다. 이러한 변형된 실시들도 본 발명의 기술 사상의 범위 내의 것이면 본 발명의 기술 및 권리범위에 속하는 것으로 해석되어야 한다
In addition to the use of the impeller can be made into a variety of different types of structure using the technical idea of the present invention to float the air by introducing air. Such modified embodiments should be construed as belonging to the technology and the scope of the present invention if they are within the scope of the technical idea of the present invention.

이와 같이 본 발명에 의하면 기포를 인위적으로 발생시켜, 폐수 속에서 부유하는 제거하기 어려운 고형물 찌꺼기를 거품이 부착하여 함께 부상하여 제거되므로 부유하는 고형물의 미세입자까지 완벽하게 제거 처리가 가능하다
As described above, according to the present invention, bubbles are artificially generated, and solid particles that are difficult to remove floating in the waste water are attached and removed together with bubbles, so that even fine particles of floating solids can be completely removed.
