Description

Technical Field

[0001] The utility model relates to the field of sedimentation tank scraper equipment, in particular to a mud clearing auxiliary device for a sedimentation tank scraper. Background Art

[0002] Sedimentation tank scraper equipment is a special equipment used to treat sludge in sedimentation tanks. It scrapes out the sludge at the bottom of the sedimentation tank through a scraper, and discharges the clear liquid on the upper layer through the overflow weir. This equipment can effectively improve the efficiency and effect of sewage treatment, and at the same time reduce the amount of sludge generated, thereby reducing the cost of sewage treatment.

[0003] At present, all domestic scrapers are not equipped with design-related auxiliary devices. There are common problems in the sedimentation tanks of wax printing and dyeing sewage treatment plants, especially. The sludge cannot be settled for too long and the desired sludge concentration cannot be discharged. If the concentration needs to be increased, it takes longer time. The characteristics of wax printing and dyeing sludge are that it is easy to agglomerate and adhere. Due to its characteristics, the longer it adheres to the scraper, the more it adheres. As a result, the sludge as a whole cannot be discharged, and it adheres to the scraper, causing the scraper to stop and stop, resulting in sedimentation tank accidents. Utility Model Content
