상기 구동수유입관(4)의 연결관부에는 고압, 고속으로 송수를 행할 수 있는 구동수노즐(7)을 설치하여 이로부터 강한 유속의 송수를 이행하고 동시에 공기흡입관(12)을 통하여 공기를 송급하고 배출관(4a) 측으로 물이 강제로 배출되면서 기체(1)의 내부가 진공상태가 되는 벤츄리관의 원리에 의해 흡입호퍼(8) 하측이 진공에 의한 흡상(吸上) 압력을 받아 수저면의 오니 등이 흡입호퍼(8)를 통하여 흡입되어 배출관(4a) 쪽으로 토사채취가 이루어질 수 있도록 구성한다.In the connecting pipe part of the driving water inlet pipe 4, a driving water nozzle 7 capable of delivering water at high pressure and high speed is installed, thereby delivering water at a strong flow rate, and at the same time supplying air through the air suction pipe 12. According to the principle of the venturi tube where the inside of the gas 1 is vacuumed while the water is forcibly discharged to the discharge pipe 4a, the lower side of the suction hopper 8 receives the suction pressure caused by the vacuum, The back is sucked through the suction hopper 8 is configured to allow the soil extraction to the discharge pipe (4a).
그리고 상기 흡입호퍼(8) 내부 하측에는 분쇄스크류우(9)를 횡설하여 유압 등으로 구동하는 모터(10)로 회전되게 하고, 분쇄스크류우(9)의 상부에는 일정한 망목(網目)을 갖는 이물질여과망(11)을 설치하여 모터(10)로 분쇄스크류우(9)를 회전시키면서 채취작업을 이행할 수 있도록 구성한다.And the lower side inside the suction hopper (8) to roll the grinding screw (9) to be rotated by the motor (10) driven by hydraulic pressure, etc., the upper part of the grinding screw (9) foreign matter having a constant mesh (網 目) The filter net 11 is installed to rotate the grinding screw 9 with the motor 10 so as to perform the collecting operation.
그리고 상기 기체(1)에 연결된 배출관(4a)측은 전후로 내경이 상이한, 즉 기체(1)의 전측은 내경이 작은 제1배출관(5)으로 구성하고, 후측은 이 보다는 내경이 큰 제2배출관(6)으로 구성하여 송수되는 유속의 증대에 보다 기여할 수 있도록 구성한 것이다.And the discharge pipe (4a) side connected to the gas (1) has a different inner diameter before and after, that is, the front side of the gas (1) is composed of a first discharge pipe (5) having a small inner diameter, the rear side is a second discharge pipe having a larger inner diameter ( 6) is configured to contribute more to the increase in flow rate.
상기와 같이 구성된 본 발명은 수저면에 적층된 오니의 수거 및 모래 등과 같은 각종 골재를 채취하는 등의 용도로 사용되는 것으로서, 이의 작용을 이하에 보다 상세히 설명하면 다음과 같다.The present invention configured as described above is used for the purpose of collecting various aggregates, such as the collection of sludge and sand, etc. laminated on the water surface, and its action will be described in more detail below.
수거 또는 채취작업을 위하여 구동수유입관(4)으로 송수를 이행하면서 공기흡입관(12)을 통하여는 공기를 송급함과 동시에 모터(10)를 가동하여 분쇄스크류우 (9)를 일정 속도로 회전구동시킨다.While collecting water is carried out to the driving water inlet pipe 4 for collecting or collecting work, the air is supplied through the air inlet pipe 12 and the motor 10 is operated to rotate the pulverizing screw 9 at a constant speed. Let's do it.
이와 같이 분쇄스크류우(9)가 회전하면 이의 하부, 즉 수저면에 적층된 오니 등은 물과 함께 격렬하게 와류운동을 하게되어 응집상태로부터 해제되어 강한 상승 흡입력과 함께 용이하게 흡입호퍼(8) 상부로 흡입되고, 상기 흡입호퍼(8)의 상부측에서 이물질여과망(11)에 의해 1차 여과되어 일정한 입자경을 갖는 오니 또는 모래만이 선별되어 상승한 후 배출관(4a)으로 송출됨으로서 오니의 수거 및 모래 등의 채취가 이루어진다.As such, when the grinding screw 9 rotates, the lower portion thereof, that is, the sludge stacked on the bottom surface, vibrates vigorously with water and is released from the cohesive state, thereby easily absorbing the hopper 8 with a strong suction force. The sludge collected by the upper part of the suction hopper 8 is filtered by the foreign matter filtering network 11 at the upper side of the suction hopper 8, and only sand having a predetermined particle size is collected and raised and sent out to the discharge pipe 4a. The sand is collected.
상기 배출관(4a)으로 오니가 송수되는 물과 함께 배출될 시에 제1배출관(5) 보다 제2배출관(6)의 내경이 크게 구성되어 있어 보다 빠른 유속으로 오니 등을 이송할 수 있게 되는 것이다.When the sludge is discharged together with the water to be discharged to the discharge pipe 4a, the inner diameter of the second discharge pipe 6 is larger than that of the first discharge pipe 5 so that the sludge can be transferred at a higher flow rate. .
따라서 본 발명에 의하면 오니 등의 수거효율 및 모래 등의 채취효율이 종래의 진공흡입장치에 비해 수배 이상 증가되어 짧은 시간에 능률적인 오니의 수거 및 모래 등의 채취를 선별적으로 행할 수 있게 되는 것이다.Therefore, according to the present invention, the collection efficiency of sludge and the collection efficiency of sand, etc. are increased several times more than the conventional vacuum suction device, so that efficient collection and collection of sludge can be performed efficiently in a short time. .
한편, 본 발명의 진공흡입장치를 설명함에 있어서, 오니수거 또는 모래 등의 채취를 실시예로 설명하였지만, 이는 용도에 따라 호수의 수저면 청소, 연안해역의 해저면 청소, 각종 해저면의 고형물 흡입채취 및 주위의 2차 오염을 발생시키지 않는 등 여러 분야에 널리 실용화할 수 있어 그 산업적 파급효과가 매우 큰 것이다.On the other hand, in the description of the vacuum suction device of the present invention, the collection of sludge collection or sand, etc. was described as an embodiment, but this is according to the purpose of cleaning the bottom surface of the lake, the bottom surface cleaning of the coastal waters, the solid suction of various sea bottom It can be widely applied to various fields, such as not causing the collection and surrounding secondary pollution, so the industrial ripple effect is very large.
이상에서 상세히 설명한 바와 같이 본 발명은 벤츄리관 원리에 의해 수저면에 적층된 오니 수거 및 모래 등을 채취토록 한 것으로서, 특히 오니 등의 흡입라인 측에 분쇄스크류우(9)를 내장하여 수저면에 강제적인 와류운동과 분쇄운동을 부여토록 하고, 배출관(4a)을 전후 내경을 달리하는 관체로 구성하여 유속을 증대토록 함으로서 오니의 수거효율 및 모래 등의 각종 골재 등의 채취효율을 대폭 향상시킬 수 있는 매우 유용한 발명이다.As described in detail above, the present invention is to collect the sludge collection and sand, etc. stacked on the water surface by the principle of Venturi tube, and particularly, the grinding screw 9 is built into the suction surface of the sludge. Forced vortex and grind movements are provided, and the discharge pipe 4a is composed of pipes with different inner and outer diameters to increase the flow rate, which can greatly improve the efficiency of collecting sludge and collecting aggregates such as sand. That is a very useful invention.
