Description

Winch type bar screen apparatus driven by winch wire in wastewater treatment

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bar screen device driven by winch wire in wastewater treatment. More specifically, in a winch type bar screen device, the structure of a rake for lifting and lowering the chain from a conventional fixed screen is Sludge contained in the wastewater passing through the fixed screen can be safely and effectively treated without spillage, improving sludge treatment efficiency, extending the service life of the bar screen device, and improving the bar screen device. The present invention relates to a bar screen device driven by winch wires in wastewater treatment.

Bar screen (bar screen) is a device that is installed obliquely inclined to the passage of the wastewater to collect sludges, such as various solids contained in the wastewater passing through the waterway and scrape it up to the top.

The bar screen device consists of a fixed screen installed at an angle to the waterway, and a rake that lifts the sludge collected on the fixed screen upward while lifting between the bar and the bar of the fixed screen. The screen and the rake pass through the waste water by the gap between the bars of the fixed screen, and sludge having a constant particle size contained in the waste water is caught by the eyes between the bars of the fixed screen, and the collected sludge is The rake driven by the chain is scraped upward to process.

Looking at the bar screen device 100 according to the prior art, as shown in Figures 10 and 11, a predetermined interval between the bar 102 and the bar to collect the sludge, such as solids contained in the wastewater in the passage through which the wastewater passes The fixed screen 101 is installed to be inclined so as to be maintained, and the rear surface of the fixed screen includes a rake 103 which is scraped upward while digging collected sludge while passing between the bars of the fixed screen. , The rake 103 is configured to scrape up the sludge collected between the bars of the fixed screen 101 while being rotated to the chain 105 by the drive motor 104.

However, since the rake 103 rotated by the chain 105 does not scrape up to the bottom of the waterway, the sludge treatment efficiency of the bar screen device 100 is significantly reduced, and when the sludge is large, the rake 103 scrapes the sludge upwards. Sludge is frequently leaked in the process, and the chain 105 is always immersed in the wastewater of the water channel, so that corrosion of the portion immersed in the wastewater proceeds rapidly, and the service life of the chain does not last long. In case of corrosion or failure of 105), the whole chain was replaced, so the replacement cost, working time and replacement method were very difficult.

In addition, as shown in FIG. 11, when the rake 103 scrapes the sludge while passing between the bars 102 of the fixed screen 101, the upper end of the bar 102 and the rake 103 is formed into a rectangular flat cross section. And, because the spacing between the bars is a constant bar between the bar has a disadvantage that the blockage occurs due to the solids between the bars, because the flat shape of the rake 103 is a lot of leakage while scraping up the solids, The solid had a flaw that could not be scraped.

The present invention was developed to solve the above problems, the bar screen device by the winch wire drive in the wastewater treatment of the present invention by installing a bucket screen to raise and lower the bar between the bars of the fixed screen by the drive means As the bucket screen rotates on the rail of the fixed screen, the sludge collected from the waste water can be scraped up by the upper conveyor belt, while the sludge can be safely handled without lifting the sludge when scraping the sludge upward. It is possible to reduce the cost of maintaining and maintaining the bar screen device.

In order to achieve the above object, in the wastewater treatment of the present invention, the bar screen device by driving the winch wire has a fixed screen which is installed to be inclined along the raw water traveling direction of the channel through which the wastewater passes, and along the rail of the fixed screen. It is composed of a bucket screen for lifting up and down the sludge collected on the fixed screen while lifting, and driving means for lifting and lowering the bucket screen by the winch wire on the rail of the fixed screen.
