As shown in the figure, conventional storage facilities such as storage tanks contain a large amount of contaminants and contaminants together with pollutants when a large amount of rainwater is initially introduced through the overflow waterway as described in the technology behind the invention. However, a large amount of contaminants flowing into the storage tank provided a cause of enormous disruption and damage to the post-treatment facility.

According to the present invention, contaminants contained in overflow water overflowing to a storage facility through an overflow channel are filtered by a semi-circular overflow screen, which is a simple technical principle, and then the caught contaminants are scraped and at the same time the contaminants are scraped. An object of the present invention is to provide a contaminant treatment device for the overflow water storage facility so that the collection can be carried out stably with a contaminant collection box provided outside the overflow waterway without falling into the overflow waterway again.

A storage facility overflow water contaminant treatment apparatus (1) according to the present invention is a semi-circular overflow screen (10); each rotating disk 20; each scraper 30; It has a specific technical configuration including the slide bar 40 and the guide link member 50 .

The semi-circular overflow screen 10 has a technical configuration in which contaminants contained in the overflow water are hung on the overflow bank 112 through which the overflow water overflows so that it is stored in the storage facility 100 after being introduced into the overflow water channel 110 . The semi-circular overflow screen may be of a perforated type, a mesh type, or a round wedge bar type, which may be selectively used depending on a location or place where a storage facility is installed.

In the above, the upper end of the semi-circular overflow screen 10 is preferably positioned more inclined toward the overflow channel 110 than the lower end mounted on the overflow bank 112 . This is to allow the foreign matter scraped by the scraper to fall to the guide link member smoothly. In addition, the semi-circular overflow screen minimizes the installation area compared to the vertical or inclined type while allowing many contaminants to be caught, and has a structure in which scraping can be performed smoothly by the scraper of the present invention.

Each rotating disc 20 has a technical configuration in which each rotating pin 21 is provided at opposite positions on both sides of the driving shaft 22 rotated by the driving means D to rotate.

In the above, the driving means D has a technical configuration for rotating the driving shaft 22, and has a technical configuration that is rotated by a driving motor and a power transmission means such as a sprocket and chain method or a pulley and a belt method. The drive shaft preferably has a length corresponding to the length of the overflow channel overflowing into the storage facility.

Each of the rotation pins 21 provided on the rotating disk 20 is rotated by the driving means D and sequentially contacted with a pair of operation bars provided on the slide bar to slide the slide bar.

Each scraper 30 scrapes impurities caught on the semi-circular overflow screen 10 on the outer peripheral surface of the drive shaft 22 where the respective rotation pins 21 are located while scraping toward the guide link member. It plays a role in dropping contaminants.

In other words, each scraper provided on the drive shaft serves to scrape up contaminants caught on the semi-circular overflow screen with rotation from the bottom to the top, and then drop them to the guide link member according to the rotation.

Here, the scraper 30 is a rake plate 32 mounted on the drive shaft 22, and a brush mounted to scrape impurities caught in the semi-circular overflow screen 10 at the end of the rake plate 32 ( 34).

Accordingly, impurities caught in the semi-circular overflow screen can be removed by scraping up relatively cleanly.

The slide bar 40 is on each of the guide blocks 42 provided on both sides of the lower side of the rotating disc 20, the respective rotating pins 21 and a pair of operating bars 44 sequentially in contact with each other. It has a technical configuration that is slid by As shown, the slide bar is provided on an installation plate installed on the overflow bank, and the portion located on the storage facility side from the overflow water channel is disposed to have an upward inclination.

In other words, the slide bar slides by a pair of operation bars in which the rotation pins provided on the rotating disk sequentially contact the guide link member so that the guide link member swings, that is, the contaminants scraped by the scraper smoothly into the guide link member. It serves as a barrier to falling.

The specific technical configuration of the pair of operation bars 44 provided in the slide bar 40 is to slide the slide bar 40 by one operation pin 21 to form the guide link member 50 in a semicircular shape. A first operating bar 44A in the form of a bar having the lower end fixed to the slide bar 40 so as to escape from the upper lower surface of the overflow screen 10, and the slide bar 40 by the other operating pin 21 By sliding the lower end is bent so that the lower end can be lifted up and down from the slide bar 40 to a predetermined height to position the guide link member 50 to the upper lower surface of the semi-circular overflow screen 10, that is, the memory of Hangul consonants (“a It is preferable to be constituted by the second actuating bar 44B in the shape of ")". A long hole is formed at a lower end of the second operation bar, and a support pin into which the long hole is inserted is formed in the slide bar, so that it has a structure capable of elevating to a predetermined height.

That is, referring to FIG. 3 , when one rotation pin 21 is in contact with the first operation bar 44A and slides the slide bar 40 toward the storage facility, the guide link member 50 is a semi-circular overflow screen 10 ) is located at a distance from the

Again, as the other rotating pin 21 comes into contact with the second operation bar 44B, the slide bar 40 slides toward the overflow water, and the guide link member 50 spaced apart from the semi-circular overflow screen 10 is placed in a semi-circular shape. It is located on the bottom side of the top of the overflow screen (10).

Next, when the other rotation pin 21 leaves the second operation bar 44B, the other rotation pin 21 comes into contact with the first operation pin 44A again and at the same time as the scraper 30 As the scraped contaminants fall onto the guide link member 50 and are guided at the same time as being spaced apart from the semi-circular overflow screen 10, contaminants are discharged to the contaminants collection box (B) located outside the overflow waterway.

As this sequence is repeated by rotation, impurities caught on the semi-circular overflow screen can be smoothly collected by the debris collection box without falling back into the overflow channel by the scraper and guide link member.

In this way, the slide bar serves to swing so that the guide link member is drawn into and spaced apart from the upper bottom surface of the semi-circular overflow screen while sliding.

The guide link member 50 is connected to the end of the slide bar 40 in the form of at least two joints, and the semi-circular overflow screen ( 10) while swinging to the bottom of the upper end has a technical configuration that guides the impurities scraped by the scraper 30 to the impurities collection box (B) provided on the outside of the overflow waterway 110 .

In the above, the specific technical configuration of the guide link member 50 is the link member 52, the bottom of which is mounted to the end of the slide bar 40 so as to be movable at a predetermined interval, and the upper end of the link member 52 is inclined at a predetermined angle. It includes a link guide plate 54 mounted to have a. The lower end of the link member connected to the slide bar is movably connected by a long hole and a pin method.

As a result, the guide link member swings toward the bottom of the upper end of the semi-circular overflow screen by the first and second operation bars of the slide bar sliding accordingly, and contaminants can be smoothly discharged without falling into the overflow water.

In addition, at least one or more guide rollers 56 provided on the side of the link guide plate 54 are provided on the installation plate P provided on the overflow bank 112 at a position corresponding to the guide roller 56 Each guide groove 58 is further included.

In other words, the guide roller and the guide groove serve to allow the link guide plate to swing more stably without departing from a certain range during the swinging process, which is an additional technology that can further stabilize the discharge of contaminants. is a component

Therefore, the present invention does not have a complicated technical configuration, but by a simple technical principle, the contaminants caught on the semi-circular overflow screen can be stably collected without falling into the overflow waterway again and into the foreign material collection box located outside the overflow waterway. .

As a result, contaminants flowing in with a large amount of rainwater instantaneously do not flow into the storage facility and are removed smoothly. conditions can be established.

4 is a partially enlarged side cross-sectional view for explaining a second embodiment of the present invention.

As shown, in the above configuration, it also provides a technical configuration in which the driving means for rotating the driving shaft is smoothly driven even in an area where electricity is not supplied.

The driving means (D) is a water wheel in the form of a water wheel connected to the drive shaft 22 by power transmission means such as sprockets and chains or pulleys and belts and rotated by the overflow water from which impurities are filtered from the semi-circular overflow screen 10 include The upper portion of the water wheel includes a guide guide D1 that smoothly guides the overflow water passing through the semi-circular overflow screen 10 to the water wheel.

In other words, when the water wheel, which is the driving means, is provided in an area where electricity is not supplied, it uses overflow water that falls from the overflow waterway to the storage facility, so that the drive shaft can be smoothly rotated without a separate driving motor driven by electricity. have possible conditions.

The drive shaft rotated by this aberration, as well as each rotating disk, each scraper, slide bar, and guide link member, which are the above-mentioned foreign matter treatment devices, are the same as the above-described technical configuration, as well as the operation and effect are the same, detailed description is omitted. .
