An air inlet pipe 50 equipped with a valve 51 is connected to 62. At this time, the bushing 90 formed with the same connecting hole 91 as the connecting hole 62 is inserted into the outer circumference of the first shaft 60, so that the air inlet pipe 50 has the bushing 90 and the first shaft ( The through holes 62 and 91 of the connection 60 are to be connected through. Accordingly, each time the connecting holes 62 and 91 and the air inlet pipe 50 communicate with each other when the first shaft 60 and the bushing 90 are rotated by the reducer 30, the compressed air is connected to each connecting hole 62. Will flow into the (91).
제 1 샤프트(60)와 분사관(70) 및 제 2 샤프트(41)의 연결 구조에 대해 설명하면,Referring to the connection structure of the first shaft 60, the injection pipe 70 and the second shaft 41,
먼저 제 1 샤프트(60)의 하측에도 통공(61)의 하측부와 관통되는 다수개의 연결공(63)이 형성되어져 있으므로, 하측의 연결공(63)에는 분사관(70)을 장착하고, 그 외주연으로는 부싱(90)을 삽입하는데, 이때 분사관(70)은 절곡부분이 만곡된 "ㄱ"자 형성으로 형성되어져 있어 챔버 하우징(10) 내부에 형성된 필터부(20)의 상측을 지나 측면에 위치하게 된다. 이때 축이음(47)을 통해 제 1 샤프트(60) 종단에는 통공(45)이 형성된 제 2 샤프트(41)가 결합되어져 있으므로, 제 2 샤프트(41)와 함께 제 2 샤프트(41)에 형성된 브러쉬암(40)의 회전이 가능하게 된다. 상기에서, 브러쉬암(40)은 도 4에 도시된 바와 같이 한쌍의 연결패널(42)(42')이 소정의 이격간격을 가지도록 형성한 후 하나의 연결패널(42)에만 브러쉬(44)를 장착하는데, 이는 브러쉬(44)와 압축공기를 통해 필터부(20)에서 분리된 슬러지들을 제 2 샤프트(41) 중심부의 통공(45)으로 모으기 위함이다.First, since a plurality of connecting holes 63 penetrating the lower part of the through hole 61 are formed in the lower side of the first shaft 60, the lower connection hole 63 is equipped with the injection pipe 70, and Bushing 90 is inserted into the outer circumference, wherein the injection pipe 70 is formed in the form of a bent portion of the "b" is formed to pass through the upper side of the filter portion 20 formed in the chamber housing 10 It is located on the side. At this time, since the second shaft 41 having the through hole 45 is coupled to the end of the first shaft 60 through the shaft joint 47, the brush formed on the second shaft 41 together with the second shaft 41. The arm 40 can be rotated. In the brush arm 40, as shown in FIG. 4, the pair of connecting panels 42 and 42 ′ is formed to have a predetermined interval, and then only the brush 44 is connected to one of the connecting panels 42. This is to collect the sludge separated from the filter unit 20 through the brush 44 and the compressed air to the through-hole 45 of the center of the second shaft (41).
제 2 샤프트(41)와 슬러지 배출관(80)의 연결 구조에 대해 설명하면,Referring to the connection structure of the second shaft 41 and the sludge discharge pipe 80,
먼저 제 2 샤프트(41)의 종단은 챔버 하우징(10) 하측부에 형성된 격벽(11) 중심으로 고정되는데, 이때 제 2 샤프트(41)는 축이음(47)을 통해 고정 연결하고, 상기 축이음(47) 하측으로 슬러지 배출관(80)을 위치시킨 후, 축이음(47)과 슬러지 배출관(80) 외주연으로 부싱(90)을 장착하여 연결 고정시킨다.First, the end of the second shaft 41 is fixed to the center of the partition wall 11 formed in the lower portion of the chamber housing 10, wherein the second shaft 41 is fixedly connected through the shaft joint 47, the shaft joint (47) After the sludge discharge pipe 80 is positioned below, the bushing 90 is mounted and fixed to the outer periphery of the shaft joint 47 and the sludge discharge pipe 80.
본 발명에서 압축공기의 유입과정 및 그로 인한 슬러지의 배출과정에 대해 설명하면,Referring to the inflow process of the compressed air and the discharge process of the sludge resulting from the present invention,

It is introduced into the injection pipe 70 of the compressed air is injected into the injection hole 71 formed in the injection pipe (70). At this time, since the injection pipe 70 is rotated in coordination with the first shaft 60 and the second shaft 41, compressed air is injected from the injection hole 71, and at the same time the brush (40) mounted on the brush arm (40) 44 is to remove the sludge while sweeping the surface of the filter unit 20, which will be described in more detail, that is, the injection pipe 70 and the brush arm 40 while rotating the outer periphery of the filter unit 20 Compressed air is injected into the filter unit 20. At this time, compressed air is injected into the space formed between the filter units 21 to remove the sludge adsorbed or fixed between the filter units 21, and the compressed air is compressed. The sludge removed through the air and the sludge removed through the brush are introduced into the through hole 45 of the second shaft 41 through the sludge inlet 43 of the brush arm 40. And the sludge introduced into the through hole 45 is introduced into the sludge discharge pipe 80 again, it is discharged to the outside.
이상에서 살펴본 바와 같이 기존 필터(100)는 브러쉬(44)만으로 필터 유니트(21) 사이사이에 흡착 또는 고착된 슬러지의 제거가 힘들고, 슬러지의 배출 또한 불편한 반면, 본 발명은 브러쉬(44) 뿐만 아니라, 압축공기의 분사를 통해 필터 유니트(21) 사이에 흡착 또는 고착된 슬러지들을 용이하게 제거할 수 있을 뿐만 아니라, 필터부(20)에서 제거된 슬러지들은 브러쉬암(40)의 슬러지 유입부(43)를 통해 중심의 제 2 샤프트(41)로 모여진 후, 슬러지 배출관(80)을 통해 외부로 용이하게 배출할 수 있다.As described above, the existing filter 100 is difficult to remove the sludge adsorbed or stuck between the filter units 21 by the brush 44 alone, and the discharge of the sludge is inconvenient, but the present invention is not only the brush 44. In addition, the sludge adsorbed or stuck between the filter units 21 may be easily removed through the injection of compressed air, and the sludges removed from the filter unit 20 may be sludge inlets 43 of the brush arm 40. After being gathered to the center second shaft 41 through), it can be easily discharged to the outside through the sludge discharge pipe (80).
이와같은 본 발명은 하우징 챔버의 상단으로는 하우징 챔버 내부의 분사관으로 유입되는 공기 유입관을 형성하고, 하단으로는 하우징 챔버 내부의 제 2 샤프트와 연결되는 슬러지 배출관을 형성한 후, 분사관에 형성된 분사공으로 압축공기를 분사시킴으로써, 필터부에 흡착 또는 고착되어 제거가 어려운 슬러지들을 용이하게 제거할 수 있을 뿐만 아니라, 그로 인하여 여과 효율을 증대시키고, 제거된 슬러지들은 중심으로 모아 슬러지 배출관으로 용이하게 배출시킬 수 있는데 그 효과가 있다.As described above, the present invention forms an air inlet pipe introduced into the injection pipe inside the housing chamber at the upper end of the housing chamber, and forms a sludge discharge pipe connected to the second shaft inside the housing chamber at the lower end thereof. By injecting compressed air into the formed injection hole, sludge that is difficult to remove due to adsorption or sticking to the filter part can be easily removed, thereby increasing the filtration efficiency, and the removed sludge is collected at the center to facilitate the sludge discharge pipe. It can be discharged, but it has an effect.
