Dredger 100 according to the present invention is provided with a settling portion 104 to precipitate particles that can be precipitated in the dredging, such as soil and sludge sucked through the dredging head device 1, the settling portion 104 ) Is connected to one side of the circulation pipe (4) for discharging the dredging free water remaining after the dredged water settled. The other side of the circulation pipe 4 is connected to the dredging head device 1, the dredging free water discharged through the settling section 104 is supplied back to the dredging head device 1 through the circulation pipe (4). .
구체적으로 본 발명에 따른 준설헤드장치(1)는, 저면이 개방되어 있고 전후면 폐쇄되어 있으며 좌우측면에는 선택적으로 개방되는 한 쌍의 도어(12)가 형성되어 있는 흡입구(吸入具)(11)를 포함하고 있다. 즉, 상기 흡입구(11)는, 폐쇄된 전후면과, 개방된 저면과, 선택적으로 개방되는 한 쌍의 도어(12)가 형성되어 있는 좌우면과, 흡입통로(14)가 형성되어 있는 상부면으로 이루어진 상자(box)형상을 가지고 있다. 상기 흡입구(11)의 중앙에는 회전에 의해 와류 형성시키면서 준설물을 파쇄하는 에지테이터(agitator)(13)가 설치되어 있고, 상기 흡입통로(14)는 흡입구(11)의 상부면에서 상기 에지테이터(13)의 주변을 감싸는 형태로 형성되어 있다. 상기 흡입통로(14)는 배토관(2)과 연결되어 있다. Specifically, the dredging head device 1 according to the present invention has a suction opening 11 formed with a pair of doors 12 having a bottom surface opened, a front and back side closed, and selectively opening at left and right sides. It includes. That is, the suction port 11 has a closed front and rear surface, an open bottom surface, a left and right surface on which a pair of doors 12 are selectively opened, and an upper surface on which the suction passage 14 is formed. It has a box shape. At the center of the suction port 11 is provided an edge data 13 (agitator) 13 for crushing the dredging while forming a vortex by the rotation, the suction passage 14 is the edge data at the upper surface of the suction port 11 It is formed in the shape surrounding the periphery of (13). The suction passage 14 is connected to the discharge pipe (2).
한편, 본 발명에서, 상기 흡입구(11)에서 상기 도어(12)가 형성되어 있는 측면 쪽의 상부 내면에는, 순환관(4)을 통해 다시 공급되어 오는 준설 여수가 토출되는 토출부(3)가 형성되어 있다. 도 5는 상기 흡입구(11)를 실선으로 도시한 개략적인 사시도인데, 도 5에 개략적으로 예시된 것처럼, 상기 토출부(3)는 상기 흡입구(11)에서 상기 도어(12)가 형성되어 있는 측면 쪽으로 길게 형성될 수 있으며, 도면에 도시된 것처럼 돌출된 슬릿 형상으로 형성될 수 있다. 물론 토출부(3)는 이와 같은 길게 형성된 돌출 슬릿 형상에 한정되지 아니하며, 원형이나 노즐 형태로 이루어질 수도 있으며, 그 형성 위치 역시 도어(12)가 형성된 측면 쪽 뿐만 아니라, 흡입구(11)의 폐쇄되어 있는 전후면 쪽의 상부 내면에도 형성될 수 있다. 상기 토출부(3)는, 상기 흡입구(11)에 일측이 연결되어 있는 순환관(4)과 연결되어 있다. 즉, 순환관(4)의 일측 단부는 흡입구(11)에서 토출부(3)와 연결되는 것이다. On the other hand, in the present invention, the discharge portion 3 for discharging the dredging free water which is supplied again through the circulation pipe (4) on the upper inner surface of the side of the side in which the door 12 is formed in the inlet 11 Formed. FIG. 5 is a schematic perspective view showing the suction port 11 in a solid line, and as schematically illustrated in FIG. 5, the discharge part 3 has a side at which the door 12 is formed at the suction port 11. It may be formed to be long toward the side, it may be formed in a protruding slit shape as shown in the figure. Of course, the discharge part 3 is not limited to the elongated protruding slit shape, and may be formed in the shape of a circle or a nozzle, and the forming position thereof is also closed on the suction port 11 as well as the side surface on which the door 12 is formed. It can also be formed on the upper inner surface of the front and rear side. The discharge part 3 is connected to a circulation pipe 4, one side of which is connected to the suction port 11. That is, one end of the circulation pipe 4 is connected to the discharge part 3 at the suction port 11.
다음에서는 이와 같은 구성을 가지는 준설헤드장치(1)와, 이를 포함하는 준설기(100)의 작동에 의하여 준설이 이루어지는 방법의 각 단계를 살펴본다. Next, look at each step of the method of dredging by the operation of the dredging head device 1 having such a configuration, and the dredger 100 including the same.
아암(103)이 회동하여 준설헤드장치(1)가 준설할 바닥면에 닿게 되고, 흡입구(11)의 일측의 도어(12)가 개방된 상태에서 개방된 도어(12) 방향으로 준설헤드장치(1)가 수평이동하게 된다. 그에 따라 오니 등의 준설물 개방된 도어(12) 방향으로 밀려들어 오게 되고, 흡입구(11) 내의 에지테이터(13)가 회전하면서 준설토, 오니 등의 준설물 파쇄한다. 파쇄된 준설물(준설토, 오니 등)은 흡입구(11)에서 흡입되어 흡입통로(14) 및 배토관(2)을 거쳐 침전부(104)로 이송된다. 이 때, 준설토, 오니뿐만 아니라 물도 함께 흡입되어 이송된다. The arm 103 is rotated to reach the bottom surface on which the dredging head device 1 is to be dredged, and the dredging head device is opened in the direction of the open door 12 in a state in which the door 12 on one side of the suction port 11 is opened. 1) moves horizontally. As a result, the dredgers, such as sludge, are pushed into the open door 12 direction, and the dredges such as dredged soil and sludge are broken while the edge data 13 in the suction port 11 rotates. The crushed dredged water (dredged soil, sludge, etc.) is sucked by the suction port 11 and is transferred to the precipitation part 104 via the suction passage 14 and the discharge pipe 2. At this time, not only dredged soil and sludge, but also water is sucked and transported.
침전부(104)에서는 자연 침강에 의해 준설토 등의 침전이 가능한 입자들이 침전되고, 기타 준설 여수는 순환관(4)으로 방출되는데, 순환관(4)을 통해 흘러온 준설 여수는 상기 흡입구(11)의 상부 내면에 형성된 토출부(3)를 통해 흡입구(11)의 내부로 배출된다. 이렇게 토출부(3)를 통해 배출된 준설 여수는 일종의 커튼 역할을 하게 되어, 개방된 도어(12)를 통해 준설물을 긁어 낼 때 흡입구(11) 외부의 물이 흡입구(11)로 유입되는 것을 막는 기능을 발휘하게 된다. 한편, 에지테이터(13)의 회전에 의해 준설토, 오니 등이 파쇄되어 흡입통로(14)로 흡입될 때, 토출부(3)를 통해 배출된 준설 여수는 준설토, 오니 등과 함께 다시 흡입통로(14)로 흡입된다. 즉, 흡입구(11) 내로 배출된 준설 여수는 파쇄된 준설토, 오니 등과 함께 다시 흡입통로(14) 내로 흡입되는 것이다. 이와 같이 파쇄된 준설토, 오니 등이, 순환 재공급 된 준설 여부와 함께 흡입통로(14)로 흡입되므로, 흡입구(11) 외부의 물이 유입되지 않아도, 준설토 등이 쉽게 흡입통로914)로 흡입될 수 있게 된다. 이렇게 흡입된 준설 여수는 배토관(2), 침전부(104) 및 순환관(4)을 통해 폐쇄적인 형태로 계속 순환하게 된다. In the settling section 104, particles that can be settled, such as dredged soil is precipitated by natural sedimentation, and other dredged sewage is discharged into the circulation pipe (4), the dredging free water flowing through the circulation pipe (4) is the inlet 11 Through the discharge part 3 formed on the upper inner surface of the discharge port 11 is discharged into the interior. The dredged effluent discharged through the discharge part 3 serves as a kind of curtain, so that water outside the suction port 11 flows into the suction port 11 when scraping the dredged water through the open door 12. Prevents the function. On the other hand, when the dredged soil, sludge, etc. are broken by the rotation of the edge data 13, and is sucked into the suction passage 14, the dredging free water discharged through the discharge portion 3 is back together with the dredged soil, sludge, etc. Inhaled). That is, the dredged effluent discharged into the suction port 11 is sucked back into the suction passage 14 together with the crushed dredged soil and sludge. Since the dredged soil, sludge, etc., crushed in this way, are sucked into the suction passage 14 together with the dredged resupply, the dredged soil and the like can easily be sucked into the suction passage 914 even if water outside the suction port 11 is not introduced. It becomes possible. Dredged Yeosu sucked in this way is continuously circulated in a closed form through the discharge pipe (2), sedimentation unit 104 and the circulation pipe (4).
이와 같이 본 발명에서는 준설 과정에서 발생한 토사 부유물, 오니 부유물이 떠다니는 준설 여수가 무단으로 바다나 하천으로 방류되는 것이 아니라, 준설헤드장치(1)의 흡입구(11)로 다시 공급되어, 준설물과 함께 흡입되고, 계속하여 순환하는 구조를 가지고 있으므로, 준설 여수의 방류로 인한, 주변 물의 탁도 증가, 수질의 저하, 악취 발생 등의 수질 오염을 예방할 수 있게 된다. As described above, in the present invention, the dredged sewage floating in the dredging process and sludge float is not discharged into the sea or the river without permission, but is supplied back to the suction port 11 of the dredging head device 1, Since it has a structure which is sucked together and continues to circulate, it is possible to prevent water pollution such as increased turbidity of the surrounding water, deterioration of water quality, odor generation due to the discharge of dredged water.
