Description

Technical Field

[0001] The utility model relates to the technical field of scraper-suction mud machines, in particular to a peripheral transmission type scraper-suction mud machine. Background Art

[0002] Peripheral drive scraper suction machine is mainly used in radial flow sedimentation tanks with a pool diameter of about 20m in water supply or drainage projects. The water to be treated enters from the central tube water inlet pipe, enters the sedimentation tank through the steady flow tube, and then diffuses and settles around. The clean water flows out from the overflow weir at the edge of the pool, and the sediment is collected by the scraper to the suction port, and then discharged from the suction pipe.

[0003] During the operation of the existing peripheral drive scraper and suction machine, sludge is deposited at the bottom of the pool. When the scraper rotates at the bottom of the pool, some of the sediment scraped up by the scraper may be in the form of flakes or blocks. When the suction pipe sucks out the scooped sediment, these block or flake sediments are very likely to clog the suction pipe, resulting in defects in the use of the peripheral drive scraper and suction machine.
