【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. FIG. 1 shows an embodiment of this invention. In this embodiment, 1 is the side wall of the sedimentation basin, which indicates the vicinity of the end of the sedimentation basin, and the same side wall 1 is one of the opposite sides. A communication passage 2 is formed on both side walls 1 and 1 by a chipping operation, and a long trough 3 is fixedly installed between both side walls 1 and 1 via a mounting means such as an angle (not shown). There is.

As shown in the figure, the trough 3 has a U-shape with its opening facing upward, and is provided with a bottom wall 4, a front wall 5, and a rear wall 6, and the upper end of the front wall 5 is at the front. In addition to the front projection piece 7 protruding horizontally, the rear wall 6 is also provided with a rear projection piece 8. The front protrusion 7 is set lower than the water surface 10, and the rear protrusion 8 is set higher than the water surface 10.

End plates 12 having openings 11 are fixed to both ends of the trough 3, and the trough 3 is fixed so that the openings 11 are aligned with the communication passages 2. A long rubber seal 13 is fixed on the front projecting piece 7, and the seal 13 is in contact with the seal 13 at the upper front of the seal 13 to prevent water from entering from the front. The rotary shaft 14 is provided. Both ends of the rotary shaft 14 are rotatably supported by bearings (not shown) of the end plate 12.

A hollow weir (float) 15 is fixed to the rotating shaft 14 so as to rotate integrally and move up and down with the water surface 10 as a boundary. Both ends of the weir 15 are fixed to each other by mounting plates 16, and one of the mounting plates 16 shown in the figure has a shaft 17 oriented in the longitudinal direction of the trough 3. A rod 19 oriented vertically is attached to the shaft 17 via a boss 18.

On the other hand, a shaft 21 protrudes from the inner surface of the end plate 12, and a boss 22 mounted via the shaft 21 has a front arm 23 and a rear arm 24 swingably extending. A balancer 25 is attached to the rear arm 24 so as to be movable back and forth, and a water tank 26 is attached to an end of the front arm 23.

The water tank 26 is a cylindrical body, and an overflow port 27 is opened in a half-moon shape at the upper end at the end portion thereof, and a vertical slit-shaped fine drainage port 28 continuous to the overflow port 27 is provided at the lower part thereof. Are formed. The overflow port 27 is for draining the excess water first when the supplied water is excessive, and the fine drain port 28 gradually discharges the remaining water to allow the remaining water in the water tank 26 to be discharged. It is for keeping the amount of water constant.

Then, a water supply pipe 30 that also communicates with a trough provided in another sedimentation basin is passed through the trough 3, and water is supplied from the pipe 30 into the water tank 26 through a supply hose 31. It has become. A bracket 32 is provided in the middle of the front arm 23, and the rod 19 is vertically adjustable via a shaft 33 attached to the bracket 32.

Further, a suspension rod 34 is provided below the water tank 26, and a water level following type lower limit float 35 is suspended via the rod 34. The float 35 floats on the water surface 10 when it descends together with the water tank 26 and comes onto the water surface 10, and restricts further descending operation. The float 35 follows the fluctuation of the water level, and when the water level is low, allows the water tank 26 to descend until it lowers, and when the water level is high, does not lower the water tank 26 too much. Therefore, the descent limit of the weir 15 is also defined by the water level following operation of the float 35.

The shaft 21 may be attached to another place, for example, on the rear projecting piece 8. Further, the weir 15 is a vertically swinging type, but may be a vertically moving type. Further, the trough 3 may have another geometric shape such as a round shape. In the above-described embodiment, the trough 3 is attached to the side wall 1 by an angle or the like, but the trough 3 may be attached to the end of the short pipe inserted into the communication passage 2. Further, in the above-described embodiment, the driving means such as the water tank 26 and the arm 23 is provided on one side of the trough 3, but they may be provided on both ends of the trough 3.

To explain the operation of this suspended matter removing device, FIG. 1 shows a state in which the water in the water tank 26 is discharged and the weir 15 floats above the water surface. From this state, water is supplied into the water tank 26 through the water supply pipe 30 and the supply hose 31. The surplus of the water in the water tank 26 is discharged through the overflow port 27. As a result, the balancer 25 is lifted and the weir 15 is pushed below the water surface, whereby the scum S ... On the water surface 10 is attracted into the trough 3 together with the water. These scum S and the water flow through the trough 3, pass through the next trough and the subsequent trough, and are discharged through the water collecting pit.

Note that scum and water from the upstream side flow into the communication passage 2 in FIG. Then, the water in the water tank 26 is gradually discharged through the slight drainage port 28, the water tank 26 becomes gradually lighter, and the front arm 23 is lifted up due to the weight of the balancer 25 and the buoyancy of the weir 15. The arm 24 is lowered. Along with this, the weir 15 floats and the attraction of the scum S ... Stops.
