Abstract

The invention is a sludge dredging boat to prevent turbidity by collecting waste material through a sludge suction pipe after crushing it using the impeller screw. In order to dredge waste sludge accumulated on the bottom of a harbor, river, dam, reservoir, culvert, nursery, or upper stream of a dammed pool, a hull (10) connected to the bank with wire rope (11) lowers a dredging machine (20) to the bottom. Then an oil pressure motor (30) operates, the impeller screw shaft (42) rotates, and the crush cutter (50) and impeller screw (41) also rotates. Sludge concentrated on the center of the impeller screw shaft (42) is crushed by the crush cutter (50), discharged from a sludge suction pipe (22) linked to the impeller screw shaft (40), filtered by the discharge exit near earth and sand tube and its remnants are formed into a cake to prevent waterway pollution.

본 발명은 항만, 하천 댐, 유수지, 취수장, 암거, 가두리양식장, 수중보상류 등 수중바닥에 퇴적된 이물질등의 슬러지를 준설할 수 있는 무혼탁 슬러지 준설선에 관한 것으로서, 무동력 준설선체의 준설기기에 유압모우터에 의하여 수동되는 임펠러스크류체를 형성하여, 이 임펠러스크류체에 의하여 이물질 등의 슬러지들을 중앙으로 이송시키면서 이들을 분쇄시키어, 슬러지흡입관을 통하여 수거되도록 하므로써, 준설작업중에 수질을 혼탁시키지 않고 준설할 수 있는 무혼탁 슬러지 준설선에 관한 것이다.The present invention relates to an undamaged sludge dredger capable of dredging sludge such as debris deposited on the water bottom such as harbors, river dams, reservoirs, intake stations, culverts, cage farms, and underwater replenishments. The impeller screw body which is manually operated by the motor is formed, and the sludge such as foreign matter is transferred to the center by the impeller screw body to be crushed and collected through the sludge suction pipe, so that the dredging work can be dredged without turbid water quality. It is about a mud-free sludge dredger.

종래의 오염된 하천, 항만 등의 수중바닥에 퇴적인 이물질들의 슬러지를 준설함에 있어서는, 대표적인 예로 제1도에 도시한 바와 같이 선체(1)에 준설기기(2)를 장착하여 준설하고자 하는 곳에 선체(1)를 이동시킨 후, 리프트장치(4)등을 이용하여 준설기기를 물속에 집어 넣어 작업할 수 있도록 되어 있는 것이며, 또한 준설기기(2)의 첨단에는, 선체(1)의 구동모우터에 의하여 구동력이 전달되는 구동축(5)에 원추형상의 굴삭체(3)가 연결되어 회전되도록 되어 있어서, 굴삭체(3)의 회전에 의하여 수중바닥의 퇴적된 슬러지를 굴삭시킬 수 있도록 되어 있다.In dredging the sludge of the foreign matter deposited on the underwater bottom of the conventional polluted rivers, harbors, etc., as shown in FIG. 1, the hull 1 is equipped with a dredging device 2 to be dredged After moving (1), the dredging equipment can be put under water by using the lift apparatus 4, etc., and at the tip of the dredging equipment 2, the driving motor of the hull 1 is carried out. The conical excavator 3 is connected to the drive shaft 5 to which the driving force is transmitted, and is rotated, so that the sludge accumulated in the underwater bottom can be excavated by the rotation of the excavator 3.

또한, 위와 같이 굴삭된 슬러지는 슬러지흡입관(6)을 통하여 선체(1) 위로 이송시킬 수 있도록 되어 있다.In addition, the sludge excavated as described above can be transferred to the hull 1 through the sludge suction pipe (6).

The water quality of the cloud would rather result in polluting the water quality.

또한, 슬러지가 일반공장을 제외하고는 찌꺼기하고 혼합된 퇴적토라서 준설작업시에 굴삭체에 또는 슬러지흡입관에 이물질이 걸려서 이물질들을 제거하여야 하는 등으로 작업능률이 현저히 떨어지는 문제점이 있었다.In addition, since the sludge is a sediment and mixed sedimentation soil except in the general factory, there is a problem that the work efficiency is significantly reduced due to the foreign matter caught in the excavator body or the sludge suction pipe during dredging work and the like.

그리고, 상기 분쇄커터(50)를 중심으로 임펠러스크류축(42)의 임펠러스크류(41)가 서로 대향되게 형성되어 이물질을 임펠러스크류축(42)의 중앙쪽으로 이송시킬 수 있도록 되어 있다.The impeller screw 41 of the impeller screw shaft 42 is formed to face each other with respect to the grinding cutter 50 so as to transfer foreign matter toward the center of the impeller screw shaft 42.

상기 임펠러스크류(41)의 원주에는 등간격으로 칼퀴(43)를 등간격으로 형성하여 임펠러스크류(41)가 구동할때 미끄럼없이 구동될 수 있도록 되어 있다.The circumference of the impeller screw 41 is formed at equal intervals so that the rake 43 is equally spaced so that the impeller screw 41 can be driven without sliding.

상기와 같이 구성된 본 발명의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

항만, 하천, 댐, 유수지, 취수장, 암거, 가두리양식장, 수중보상류 등 수중바닥에 퇴적된 이물질 등의 슬러지를 준설하고자 하는 곳에 본 발명의 선체(10)를 띄어 와이어로우프(11)를 하천 등의 뚝에 연결시킨 후, 선체(10)의 준설기기(20)를 제1도에 도시한 바와 같이 수중의 바닥에 위치시킨다.Floating wire hull (11) of the present invention in the place to be dredged sludge, such as foreign matter deposited on the bottom of the water, such as harbors, rivers, dams, reservoirs, intake, culverts, cages, underwater compensation After connecting to the stack, the dredging device 20 of the hull 10 is positioned at the bottom of the water as shown in FIG.

이후, 유압모우터(30)를 구동시키게 되면, 임펠러스크류축(40)의 임펠러스크류축(42)이 회전함에 따라서 임펠러스크류축(42)의 임펠러스크류(41)와 분쇄커터(50)가 회전하게 된다.Thereafter, when the hydraulic motor 30 is driven, the impeller screw 41 and the grinding cutter 50 of the impeller screw shaft 42 rotate as the impeller screw shaft 42 of the impeller screw shaft 40 rotates. Done.

상기의 임펠러스크류(41)가 제2도 및 제3도에 나타낸 바와 같이 상기 분쇄커터(50)를 중심으로 임펠러스크류축(42)의 임펠러스크류(41)가 서로 대향되게 즉, 스크류의 나선이 대향하게 형성되어 이물질을 임펠러스크류축(42)의 중앙쪽으로 이송시키게 된다.As shown in FIG. 2 and FIG. 3, the impeller screw 41 of the impeller screw shaft 42 is opposed to each other, that is, the screw spiral It is formed to face the foreign matter to the center of the impeller screw shaft 42.

따라서, 임펠러스크류축(42)의 중앙쪽으로 모아지는 슬러지는 분쇄커터(50)에 의하여 분쇄되어 임펠러스크류축(40)와 연결된 슬러지흡입관(22)을 통하여 빠져나가서 준설선의 토사배출구에 형성한 고성능 특수탈수기(도시생략)에서 혼탁된 배출수는 필터링 처리하여 다시 맑은 물은 하천이나 강으로 흘러 보내고, 찌꺼기는 케이크화하여 하천의 재오염을 방지할 수 있는 것이다.Therefore, the sludge collected toward the center of the impeller screw shaft 42 is pulverized by the crushing cutter 50 and exits through the sludge suction pipe 22 connected to the impeller screw shaft 40 to form the soil discharge port of the dredger. Effluent turbidity from the dehydrator (not shown) is filtered to allow clear water to flow into rivers or rivers, and residues are caked to prevent recontamination of rivers.

이상과 같이, 본 발명은 준설기기의 첨단에 임펠러스크류축의 나선이 스크류축의 중앙으로 대향하게 형성된 임펠러스크류체가 유압모우터에 의하여 회전되도록 하므로써, 수중바닥의 이물질 등의 슬러지가 임펠러스크류체의 중앙으로 모아지도록 하고, 모아진 슬러지는 커터에 의하여 분쇄되어서 슬러지흡입관을 통하여 추출시킬 수 있도록 하여, 준설작업중에 수질을 혼탁시키지 않고 준설할 수 있는 것이다.As described above, the present invention allows the impeller screw body formed at the tip of the dredging machine so that the spiral of the impeller screw shaft faces the center of the screw shaft is rotated by the hydraulic motor, so that sludge such as foreign matter on the underwater bottom is moved to the center of the impeller screw body. The collected sludge is crushed by the cutter and can be extracted through the sludge suction pipe so that the dredging can be dredged without turbid water quality.
