Description
본 고안은 침전지(沈澱池)에 관한 것으로, 특히 침전지의 정화수조를 세척하기 위한 브러쉬를 회전시켜 세척을 더욱 확실하게 하도록한 침전지용 정화수조 세척장치에 관한 것이다.The present invention relates to a sedimentation basin, and more particularly, to a clarification basin cleaning apparatus for a sedimentation basin by rotating a brush for cleaning a septic tank of a sedimentation basin.
물속에 섞인 흙과 모래등의 이물을 가라앉히어 물을 맑게 만들기 위한 침전지는 기부 상에 원형의 큰 그릇 형상의 침전지가 구비되고 침전지 둘레 상부에는 정화수조가 구비되어 물의 이물을 침전시키도록 되어 있고, 침전지 중앙에는 회전체가 설치되어 있는바, 이는 하부가 침전지에 결합되고 침전지 바닥면을 따라 안내되도록 일측으로 길게 아암이 형성되어 있으며, 중심에 상측으로 돌출형성된 중심축이 구비되어 있고 그 둘레에 이를 회동시키기 위한 구동장치가 설치되어 있다.The sedimentation basin for submerging foreign substances such as soil and sand in the water to make the water clear is provided with a circular large bowl-shaped sedimentation basin on the base, and a purification tank is provided at the upper part of the sedimentation basin to sediment the foreign substance of water. In the center of the sedimentation basin, a rotating body is installed, which has an arm formed to one side so that the lower part is coupled to the sedimentation basin and guided along the bottom of the sedimentation basin, and has a central axis protruding upward from the center. A drive device for rotating it is installed.
또한 중심축에는 브리지가 연결설치되어 있고 그 단부에는 구동바퀴가 설치되어 있어 구동장치가 작동됨에 따라 브리지가 회동되어 구동바퀴가 침전지 둘레 상면에 접촉 회전되며, 이때 브리지에 연결설치된 브러쉬를 구비한 세척장치가 브리지를 따라 이동되면서 정화수조를 세척하도록 되어 있다.In addition, the bridge is connected to the central axis and the driving wheel is installed at the end. As the driving device is operated, the bridge is rotated, and the driving wheel is rotated in contact with the upper surface of the settling basin. The unit is adapted to flush the septic tank as it moves along the bridge.
그런데 이러한 종래 침전지용 정화수조 세척장치는 구동장치에 의한 브리지의 회전으로 브러쉬가 정화수조의 내면에 접촉된 상태에서 끌리면서 세척되는 비교적 소극적인 세척방법이어서 회전체의 1회전으로는 정화수조 내면을 깨끗이 세척하지 못하였고, 따라서 세척농도를 높이기 위해 브러쉬를 여러번 왕복회전시킴에 따라 작업공수 및 작업시간의 증가가 있었다.However, such a conventional clarification tank cleaning device for the sedimentation basin is a relatively passive cleaning method in which the brush is pulled and washed while the brush is in contact with the inner surface of the septic tank by the rotation of the bridge by the driving device. Failed to clean, therefore, the number of working hours and working time was increased by rotating the brush several times to increase the cleaning concentration.
상술한 문제를 감안하여 본 고안의 목적은 소제장치의 브러쉬가 브리지의 회동에 따라 침전지의 정화수조 내에서 이동되면서 동력전달원에 의해 회전되므로 브리지의 1회전으로 침전지의 정화수조를 깨끗이 소제할 수 있어 작업능률이 향상되도록 한 침전지용 소제장치를 제공하는 것이다.In view of the above problems, the object of the present invention is to clean the settling basin of the settling basin with one rotation of the bridge because the brush of the cleaning device is rotated by the power transmission source as it moves within the settling basin of the settling basin as the bridge rotates. It is to provide a cleaning device for the sedimentation basin to improve the working efficiency.
이와같은 목적을 달성하기 위한 본 고안의 침전지용 소제장치는 브리지의 이동에 안내되어 침전지의 정화수조 바닥면 및 측면등에 침전형성되는 침전물을 제거하는 장치에 있어서, 정화수조의 바닥면에 접촉되는 한쌍의 원판형브러쉬와 정화수조의 양 측면에 접촉되는 한쌍의 원판형 브러쉬와, 정화수조 양측 윗면에 접촉되는 한쌍의 원판형 브러쉬가 구비되고 각 브러쉬의 배면 중앙에는 각각 전동축이 설치되며 각 전동축은 기어에 의해 연결되어 별도의 동력전달원에 의해 동시에 회전되면서 침전지 바닥면과 측면 및 양측 윗면을 소제토록되어 있는 것을 특징으로 한다.In order to achieve the above object, the device for cleaning the sedimentation basin of the present invention is a device which is guided to the movement of a bridge to remove sediment which is formed on the bottom and the side of the purification tank of the sedimentation basin. A pair of disc brushes and a pair of disc brushes in contact with both sides of the septic tank and a pair of disc brushes in contact with the upper sides of the septic tank, each of which has an electric shaft installed at the center of each brush. Is connected by a gear is rotated at the same time by a separate power transmission source, characterized in that the sedimentation basin bottom and side and both top surfaces.

이러한 구성의 본 고안 침전지용 소제장치는 구동장치(8)가 작동됨에 따라 아암(4), 브리지(7)가 회동되어 구동바퀴(10)가 침전지(2) 상면 둘레를 따라 구르게 되는바, 이 구동바퀴(10)의 회전력에 의해 구동축(11)이 회전되어 중간축(12), 제1연결축(13)을 회전시키게 되고, 이 제1연결축(13)에 의해 제1전동축(14), 제4전동축(20)이 회전되어 제2,5브러쉬(15)(21)를 회전시킴과 동시에 제2,5전동축(16)(22)을 회전시키게 되어 제1,4브러쉬(17)(23)를 회전시키며 제3,6전동축(18)(25)에 연결된 제3,6브러쉬(19)(26)를 회전시키게 된다.In the present invention, the cleaning device for the sedimentation basin having the above-described structure, as the driving device 8 is operated, the arm 4 and the bridge 7 are rotated so that the driving wheel 10 rolls around the upper surface of the sedimentation basin 2, The driving shaft 11 is rotated by the rotational force of the driving wheel 10 to rotate the intermediate shaft 12 and the first connecting shaft 13, and the first driving shaft 13 is driven by the first connecting shaft 13. 14), the fourth motor shaft 20 is rotated to rotate the second and fifth brushes 15 and 21, and at the same time, the second and fifth motor shafts 16 and 22 are rotated. The third and sixth brushes 19 and 26 connected to the third and sixth electric shafts 18 and 25 are rotated by rotating the 17 and 23.
여기서 제1,4브러쉬(17)(23)의 회전으로 정화수조(3)의 바닥면(3b)이 깨끗이 소제되고 제2,5브러쉬(15)(21)에 의해 양측면(3a)(3b)이 소제되며 제3,6브러쉬(19)(26)의 회전으로 정화수조 양측상면(3c)(3e)이 소제 된다.Here, the bottom 3b of the purification tank 3 is cleaned by the rotation of the first and fourth brushes 17 and 23 and both sides 3a and 3b are formed by the second and fifth brushes 15 and 21. This is cleaned and the upper and lower sides 3c and 3e of the purification tank are cleaned by the rotation of the third and sixth brushes 19 and 26.
이러한 본 고안의 침전지용 소제장치는 구동장치(8)의 작동으로 브리지(7)가 침전지(2)중앙을 중심으로 회전되어 각각의 브러쉬들(17)(15)(19)(23)(21)(26)을 정화수조(3)의 바닥면(3b), 양측면(3a)(3d) 양측면(3c)(3e)에 접촉된 상태에서 이송시킴과 동시에 구동바퀴(10)의 구동력을 이용하여 브러쉬를 각각 회전시키므로 브러쉬와 정화수조(3) 각각의 면들과의 접촉저항을 증대시켜 세척력을 극대시키게 된다.The cleaning device for the sedimentation basin according to the present invention has the brushes 7, 15, 19, 23, and 21 which are rotated about the center of the sedimentation basin 2 by the operation of the driving device 8. ) 26 is conveyed in contact with the bottom surface 3b, both sides 3a, 3d and both sides 3c, 3e of the purification tank 3, and at the same time, the driving force of the driving wheel 10 is used. Since the brushes are rotated, the contact resistance of the surfaces of the brush and the purification tank 3 is increased to maximize the cleaning power.
또한 구동바퀴(10)의 회전동력을 이용하는 대신 제5도에 도시한 바와같이 보조바퀴(30)의 회전동력을 이용할 수 있는바, 브리지(7)에 케이스(9)를 설치하고 케이스(9) 하단에 힌지편(31)으로 보조바퀴(30)가 구비된 회동력(32)을 결합시킨후 케이스(9)와 회동편(32) 상단에 인장코일 스프링(33)을 설치한다.In addition, instead of using the rotational power of the drive wheel 10, as shown in FIG. 5, the rotational power of the auxiliary wheel 30 can be used. The case 9 is installed on the bridge 7 and the case 9 After coupling the rotational force 32 provided with the auxiliary wheel 30 to the hinge piece 31 at the lower end, the tension coil spring 33 is installed on the case 9 and the upper end of the rotation piece 32.
이와같이 설치된 보조바퀴(30)는 매끄럽지 못한 침전지(2)의 상면둘레를 구르면서 충격에 의한 진동이 발생되는데, 이때 인장코일 스프링(33)의 탄성력에 의해 진동을 어느정도 흡수하여 보조바퀴(30)가 그다지 크게 요동하지 않고 회전되며, 이러한 보조바퀴(30)의 축에 구동축(11)을 연결시키면 바퀴의 떨림에 의한 소제장치의 유동을 어느정도 방지시키게 되어 더욱 깨끗하게 소제할 수 있게 된다.The auxiliary wheel 30 installed in this way is a vibration caused by the impact while rolling the upper surface circumference of the sedimentation basin (2) is not smooth, at this time by absorbing the vibration to some extent by the elastic force of the tension coil spring (33) the auxiliary wheel (30) It is rotated without much shaking, and connecting the drive shaft 11 to the shaft of the auxiliary wheel 30 to prevent the flow of the cleaning device due to the shaking of the wheel to some extent to be able to clean more.
또한 제6도에 도시한 바와같이 구동축(11)을 회전시키기 위해 별도의 동력 즉 구동모터(40)를 구비, 설치할 수 있는데, 케이스(9) 내에 구동모터(40)를 설치하고, 축에 구동축(11)을 연결하여 구동모터(40)의 회전력을 구동축(11)에 전달하여 각각의 브러쉬들을 회전시킬 수도 있다.In addition, as shown in FIG. 6, in order to rotate the drive shaft 11, a separate power, that is, the drive motor 40 may be provided and installed. Connecting the 11 may transmit the rotational force of the drive motor 40 to the drive shaft 11 to rotate the respective brushes.
이상에서와 같은 본 고안에 따른 침전지용 소제장치에 의하면 각각의 브러쉬들을 축들과 기어들에 의해 회전동력을 갖는 동력전달원에 연결시켜 각각의 브러쉬가 회전하면서 정화수조를 따라 이동되므로 그 소제를 더욱 확실하게 하여 작업능률을 향상시키는 효과가 있다.According to the sedimentary cleaning device according to the present invention as described above, each brush is connected to a power transmission source having rotational power by axes and gears, so that each brush is moved along the septic tank while rotating the brush. It has the effect of improving the work efficiency by ensuring.
