BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing scum from a treatment pond such as oxylation.

[0002]

2. Description of the Related Art A treatment pond called an oxylation is a pond having an oblong plane and a partition wall in a longitudinal direction of the pond. In the pond, sewage is caused to flow in one direction, and aeration is performed therebetween. Or be done.

[0003]

In the conventional oxylation, a device for efficiently collecting a large amount of scum has not been provided.

The present invention has been made to solve such a problem, and has as its object to efficiently collect and remove scum.

[0005]

According to a first aspect of the present invention, there is provided an apparatus for removing scum flowing from a treatment pond, such as an oxylation treatment, outside the treatment pond. The scum is suspended horizontally above the water surface of the treatment pond, rotates around the horizontal axis, dams the scum by rotating in one direction, guides it in the lateral direction, and passes the scum as it is by rotating in the other direction. A weir, a driving means for rotating and driving the weir, a scum collecting unit for taking in the induced scum, and a scum collecting unit only when the upper end is lowered below the water surface in conjunction with the up and down movement of the weir Scum deriving means for introducing the scum taken into the tub and excluding the scum from the pond through a connected pipe.

[0006]

As described above, the scum can be efficiently collected by the combination of the weir, the driving means, the scum collecting section, and the scum deriving means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments. 1 to 4 show one embodiment of the present invention. Here, 1 indicates the entire oxylation, and the oxylation 1 is an oval peripheral wall 2.
And a partition wall 3 therein. In the oxygenation 1, the wastewater 4 circulates clockwise in the direction of the arrow in FIG.

A gantry 5 is fixed to the peripheral wall 2 of the oxylation 1. The gantry 5 includes a main body having a U shape as viewed from above and an auxiliary frame. The gantry 5 is manufactured using an L-shaped channel material. A closing plate 7 which is L-shaped when viewed from above and reaches a water level 6 or lower is attached to the gantry body.

A vertical column 8 is erected from the gantry main body, and a horizontal member 9 is laid horizontally via upper ends of these vertical columns 8. There are two horizontal members 9 including pulleys 10,
10 are attached.

A cylinder (drive means) 12 is mounted on the auxiliary frame, and the rod of the cylinder 12 extends downward. Reference numeral 13 denotes a weir which is horizontally rotatable between the gantry 5 and the partition wall 3 at an angle, and is rotatable.
Supported by

Three levers 15 are attached to the rotating shaft 14. The cylinder 12 is attached to one lever 15. The second lever 15 has a balancer 16
Is installed. And the pulley 1 is on the remaining lever 15
One end of a wire 17 provided through 0 is connected. The weir 13 and the balancer 16 are displaced by approximately 180 °.

The wire 17 operates in the same manner as the weir 13, that is, when the weir 13 goes down, the other end goes down.
The other end goes up when it goes up. At the other end of the wire 17, an attracting cylinder 20, which is provided to be able to move up and down in a collecting section constituted by the closing plate 7 and the peripheral wall 2, is suspended via an auxiliary suspending tool 21.

The guide tube 20 is guided up and down along a fixed tube 22 provided below the water surface.
Is to induce scum. The fixed cylinder 22 is connected to an outlet cylinder 23 that communicates with the outside of the pond. In addition, two floats 24 are attached to the outer periphery of the invitation tube 20, and the float 24 has a tapered lower portion, and buoyancy is slowly applied when entering the water surface, and the invitation tube 20 is lowered. It is configured so that braking at the time becomes gentle.

To explain the operation, the scum S flowing in the oxylation 1 passes through the water surface below the weir 13 because the weir 13 is in the raised state. And it goes around by aeration (illustration omitted). When the cylinder 12 operates and the weir 13 falls below the water level, the scum S is blocked and the scum S is flown obliquely along the weir 13 and guided into the scum collection unit.

The scum S comes on the water surface partitioned by the closing plate 7, and is attracted into the fixed cylinder 22 through the attracting cylinder 20 which is lowered below the water surface by the operation of the cylinder 12. The scum S from inside the fixed cylinder 22 is the lead cylinder 2
It is discharged outside the pond through the inside of 3. When the weir 13 rises, the attracting cylinder 20 also rises, and the attraction of the scum S is prevented.

The water surface 6 has a high state and a low state as indicated by a virtual line in FIG. In addition, on the rotating shaft 14,
A scum guide plate 26 is attached, and when the weir 13 rises, it descends to the surface of the water to guide the scum S out of the scum collection unit and passes the scum S. When the weir 13 descends, it rises greatly and collects the scum S. It is configured to be invited into the department.

As shown in FIG. 4, a guide rail 30 which is an I-shaped member is provided on the outer periphery of the partition wall 3 by a plurality of brackets 3.
1 are fixed so as to be horizontal. The guide rail 30 has an elliptical shape in plan view as shown in FIG. 1, and the guide rail 30 includes a plurality of moving bodies 32 formed by cutting a U-shaped channel material with a lip into short pieces. The rollers 33 run smoothly and stably.

The upper roller 33 is large, and the roller 33 has a sprocket 3 on its side.
4 is provided. The sprocket 34 is rotationally driven by a sprocket 36 and a chain 42 provided on a side of a motor 35 having a speed change function.

A motor 35 is fixed on a table 37, and a pump 38 driven by the motor 35 is also mounted on the table 37.
Fixed on top. The pump 38 has a pipe 40 extending below the water surface 6 and sucking up water in the water. In addition,
The motor 35 is driven using a solar cell 41 erected from the table 37 as a power supply.

A support plate 43 is fixed to the upper surface of the movable body 32 so as to extend horizontally in the pond width direction. A swing plate 45 is attached to the support plate 43 via brackets 44 so as to be able to swing back and forth, and a rubber scum shift 46 is attached to a lower portion of the swing plate 45. The lower portion of the scum shifter 46 sinks down on the water surface 39 and scrapes the scum S floating on the water surface 6. When the scum shifts toward the aeration device or the scum removal device, the scum shifter 46 swings and escapes later. Going beyond.

A horizontal water supply pipe 49 is fixed on the support plate 43 via a bracket 48. A pump 38 communicates with the pipe 49, and water from the pump 38 through the pipe 49 is blown out from the tip of a front nozzle 50, and thereby scum S on the water surface 6 is blown in a circumferential direction to remove scum. It works to bring it to the device. A weight 51 stabilizes the self-propelled performance of the entire apparatus.

In the above-described embodiment, an oval-shaped oxylation is described. However, for example, an oxylation in which a plurality of partition walls are separated from each other in parallel so that sewage flows in a meandering shape is also possible. There are applications.

Since the present invention is configured as described above, scum can be efficiently collected and removed.
