Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sludge collection system having a sludge-

The present invention relates to a sludge collecting system having sludge, which is a precipitate accumulated on a lower part of a settling tank in a water treatment plant or a wastewater treatment plant, and a sludge inducing and discharging unit for collecting floating matters (scum) floating on the water surface. More particularly, The residual sludge in the sludge collecting part is scraped by a scraper to be collected and treated as a lower part. The scum, which is a floating substance, is collected by a scraper on the water surface and discharged to the upper part. The sludge improved in the driving part of the sludge collecting part To a sludge collection system having an induction discharge.

Generally, a sludge collector for removing sludge is provided in a water treatment plant, a sewage treatment plant, and the like.

When sludge and wastewater are purified, sludge settles to the bottom of the sludge collector and floats floating on the surface of the sludge collector are generated. These sludges and floats not only rapidly pollute water quality over time, It is possible to improve the purification effect of sewage and wastewater by removing many odors and removing them quickly.

Background Art [2] Generally, a sludge collector of a water treatment facility collects sludge, which is a sediment accumulated in a lower part of a sedimentation tank, in a water purification plant or a wastewater treatment plant by scraping the collected sludge into a specific space. And the sludge is transported to a specific space.

The sludge collector includes a pair of conveying chains which are arranged in an infinite orbit and whose upper portion is disposed close to the water surface and whose lower portion is disposed close to the bottom surface and are parallel to each other, A drive sprocket for moving the transport chain, a drive motor for transmitting power to the drive sprocket, and a plurality of idle sprockets spaced apart from the drive sprocket to support the transport chain.

According to such a sludge collector, the drive sprocket is driven by the drive motor so that the transport chain is orbitally rotated, and the plate is drawn by the transport chain.

Thus, the sludge settled on the bottom of the settling tank is conveyed to the discharge hopper side by the plate 12 moving close to the bottom surface, and the plate is continued by the conveying chain, so that the orbit portion of the conveying chain close to the water surface The float floating on the surface of the water is collected and discharged to the outside.

However, such a sludge collector requires a heavy load, which often causes the conveying chain to break or the drive shaft to bend. Therefore, it is necessary to discharge the sludge heavier than water in the previous stage of the sludge collector and to reinforce the drive shaft or the idle shaft.
