Description

Moving screen device with a rotary scraper and bucket {Moving screen device with scraper}

The present invention is a moving screen device having a rotary scraper and a bucket, and if described in more detail, the scraper and the bucket are improved in a rotatable structure to be installed in a waterway to effectively remove garbage and impurities including floating objects. It relates to a moving screen device having a rotary scraper and a bucket.

In general, in places that manage water, such as sewage treatment plants, relay pumping stations, water intake stations, and rainwater treatment facilities, a moving screen device is installed by blocking the waterway to prevent various floating debris from flowing through the waterway. .

In general, a drainage pump for pumping water is installed in a drainage treatment plant or a water intake plant, and a comb-shaped screen is installed in the waterway where the influent water enters to filter floating matters such as dirt or garbage to prevent the pump from malfunctioning.

In addition, a plurality of scrapers are installed at regular intervals to remove floating objects in front of the screen, and the floating objects are automatically removed continuously while the scraper traverses along the front of the screen, but the screen contains thick branches, stones, and plastic. If a hard floating object is caught, the scraper operation is overloaded, which causes a breakdown, which caused the inconvenience of having to periodically remove the floating object by the operator.

Accordingly, in Patent Registration No. 10-1167659 disclosed in the prior art, a comb-shaped screen is installed across the waterway, but the screen is inclined and protruded forward from the bottom of the screen, and guide rails are installed on both sides of the screen so that the chain is guide rail. But the chain is rotated by a motor, and a scraper that moves along the back of the screen and protrudes in front of the screen is installed on the chain, but the scraper is folded when moving downward and unfolded forward when moving upward, and the A base plate that supports the back of the screen is installed in front of the fixing bar installed on the back of the screen, but a gap cone is installed on the base plate to maintain the gap between the screens, and the base plate is erected so that it does not interfere with the movement of the scraper. A technique has been proposed in which the scraper protrudes forward from the inclined lower part of the screen and raises the float.

In addition, in Patent Registration No. 10-1731936, which is another prior art, a rear auxiliary screen installed at the rear of the lower side of the main screen to filter impurities flowing between the main screen and the bottom of the waterway, and between the rear auxiliary screen and the lower end of the main screen. A blocking screen is installed to block the passage of contaminants in the outflow space of the main screen, the blocking screen being fixed to the side frame and extending in the width direction of the main screen, and the screen of the main screen while being suspended from the support rod. A technology including a plurality of ring-shaped blocking members arranged side by side between the bars and extending downward to collect impurities in the outflow space has been previously registered.

However, the above-described conventional techniques are intended to efficiently remove suspended matter (imposed matter) collected on the screen using a scraper (rake), but due to the structural characteristic of the scraper being formed in a plate-shaped blade structure, it is impossible to remove relatively small suspended matter. In the case of linear floats such as those with strong adsorption properties, waste ends that accumulate on scrapers and screens and obstruct water flow followed.
