Description

TECHNICAL FIELD The present invention relates to a scum removing device.

[Technical Background] The applicant has provided a float on the front side of a trough installed on the surface of a sedimentation basin so that the float floats and descends according to the movement of a flight, whereby a scum floating on the surface of the water is obtained. I previously proposed a scum removal device that was designed to attract the inside of the trough. However, since the float is manufactured integrally as a whole, the float must be designed and manufactured each time the size of the sedimentation tank on the user side is different, which causes a large loss. As a result, not only the cost is increased, but also the delivery time is delayed, and it becomes a long product as a whole, and it is difficult to transport and construct to the site.

[Purpose of device]

This invention was made in order to solve such a problem, and the purpose is to make it possible to reduce the cost of designing and manufacturing, simplify the transportation and construction, and shorten the delivery time. Another object of the present invention is to provide a scum removing device.

[Constitution of device]

The present invention has been made to solve the above-mentioned object, and in this invention, a trough shaped like a trough is fixedly installed in the sedimentation pond so that an opening formed at one side of the trough is below the water surface of the sedimentation pond. On the opening side of the trough, a vertical rocking type damming member is attached so as to float up and down across the water surface, and in the sedimentation pond, it is an arm-shaped member and rocks up and down. A rocking arm having both ends supported by a rotation fulcrum so as to move is provided, and the rocking arm is configured to rock by hitting a flight side moving in the sedimentation pond. The damming member is configured so as to be pushed down and interlocked with each other, and the damming member is configured to be able to return to the water surface by obtaining an ascending force by the weight of the swing arm and a restoring means such as buoyancy of the damming member. The dam member It is composed of a pair of common type floats provided only on both sides of the settling pond in the width direction of the pond so that the scum can be crossed by the sinking operation, and a partition plate provided between the floats. In the scum removing device, a long groove-shaped insertion slit into which the partition plate is inserted is formed on the surface of the float on the side of each partition plate, and the float and the partition plate correspond to the pond width dimension. The partition plate is positioned below the tip of the float and floats above the float when it floats. It is characterized in that it is configured to swallow.

〔Example〕

The present invention will be described below with reference to the illustrated embodiments.

1 to 4 show an embodiment of the present invention. Reference numeral 1 is a side wall of the sedimentation basin, and a trough 2 is fixed to the side wall 1. A rubber scum guide plate 3 is obliquely attached to the front side of the trough 2. A damming member 4 is connected to the front side of the scum guide plate 3 to move up and down with the water surface 23 as a boundary. The damming member 4 is
It is composed of a float 5 and a partition plate 6.

The float 5 has a hollow shape that is an isosceles triangle when viewed from the side, and the hypotenuse thereof is arranged to extend substantially along the extension of the scum guide plate 3 and its tip (top apex) 5a.
Is projected above the water surface 23 when ascending. The floats 5 are arranged in a pair on the left and right in the pond width direction.

Each of the floats 5 has a long groove-shaped insertion slit 7 formed in a diagonal direction on the surface on the partition plate 6 side. Both ends of the partition plate 6 are inserted into the slit 7,
It is adapted to be connected and fixed to an appropriate position by a bolt (fixing tool) 8. In this way, since the float 5 is a common type and standardized, even if the user requests a scum removing device for sedimentation basins with different pond widths, the scum removing device that matches it should be designed. Instead, it can be dealt with easily with a short delivery time, and it can be easily transported in a disassembled short state and can be individually constructed. Since the partition plate 6 is a slightly long plate with a margin, the above-mentioned measures can be taken quickly.

The tip 6a of the partition plate 6 is located below the tip 5a of the float 5 when floating, and is configured to swallow the scum before the float 5.

Therefore, the partition plate 6 is deeply sunk for a longer period of time than the float 5, so that when the water level in the sedimentation pond becomes low, the scum retraction ability is weakened only by the float 5, and a large scum cannot be particularly attracted. However, if the low partition plate 6 is provided, the attraction can be exerted deeply and strongly over a long period of time, so that even a large scum can always be reliably attracted through the low posture plate 6 regardless of the water level.

The float 5 floats up first and blocks the scum, but the partition plate 6 blocks it later. Meanwhile, the scum floating in the lateral area is also attracted while being attracted to the center in the width direction, which is the partition plate 6 side. As a result, scum is not accumulated on the water surface on both outer sides of the dam member 4, and no bad odor is generated, and it is also effective for maintaining the appearance.

The scum guide plate 3 can be easily dealt with by cutting it to an appropriate size according to the shape of the dam member 4.

Also, on the trough 2, left and right 1 connected to the float 5
A horizontal bar 10 for rotatably supporting the pair of support arms 9 and 9 is horizontally installed, and the horizontal bar 10 corresponds to the fact that the length of the dam member 4 is adjusted. The bar 10 is also divided into a pipe 11 on both sides and intermediate pipes 12 and 12 so that it can be expanded and contracted according to the width of the pond.

Further, a rail 13 is provided at the bottom of the pond, and a flight 15 is made to move on the rail 13 by a chain 14, but the striker 17 is interlocked by the roller 16 of the flight 15 to stop the dam. The member 4 is adapted to move.

The striker 17 is a swing arm attached to the rotation fulcrum 18.
The first projecting cam 20 is kicked by the roller 16 moving at the bottom of the pond, which is attached to one end of 19, so that the damming member 4 is largely lowered via the interlocking wire 21 and then the flat cam 22. When the roller 16 comes into contact with the dam, the damming member 4 is slightly raised for a certain period of time, but
It is made to come under 23.

Further, the roller 16 hits the second protruding cam 24, so that the damming member 4 is pushed down to the second stage by a large amount. Thereby, the scum is devised so as to be effectively attracted into the trough 2.

By the way, a fixed plate 25 is attached to the swing arm 19, and a vertical moving plate 28 is attached to the fixed plate 25 through a vertically oriented elongated hole 26 for vertical adjustment and a bolt 27. On the vertical moving plate 28, the first, second, and third striker pieces a to c are arranged in a divided manner as having a first protruding cam 20, a flat cam 22, and a second protruding cam 24, respectively.

Each of the striker pieces a to c is continuously provided via a slope 29 so that the striker pieces a to c can be expanded and contracted forward and backward by a longitudinal adjustment elongated hole 30 and a bolt 31. Like this, striker
Since 17 can be adjusted up and down, the sinking depth of the damming member 4 can be adjusted, and since it can also be adjusted forward and backward, the length of time that the damming member 4 sinks is adjusted. It is possible.

Although the swing arm of the above-mentioned embodiment is located at the bottom of the pond and hits the flight side passing through the bottom, the arm may be arranged above the water surface of the pond. In this case, the swing arm may be pushed up by a flight passing over and the damming member may be pushed down and interlocked with the other end of the swing arm. The damming member may be installed on the opposite side of the trough.

[Effect of device]

As described above, the present invention makes it possible to reduce the cost of designing / manufacturing as well as simplify the transportation / construction and shorten the delivery time.

Furthermore, since the damming member consisting of the float and the partition plate is expandable and contractible, it can be adjusted to a length that matches the pond width with a minute gap,
If it is too long, these moving parts will not hit the side wall of the pond, and if it is too short, there will be no risk that the scum will freely enter the trough side through the side of the moving part.
