The invention discloses an automatic
sedimentation scraper unloading device for a
centrifuge, comprising a pneumatic mechanism and a scraper mechanism, wherein the scraper mechanism is fixedly mounted on the pneumatic mechanism, and the scraper mechanism is connected with the pneumatic mechanism, and a lifting rod is driven to move by air pressure, so that the scraper mechanism can move up and down in a
rotating drum of the
centrifuge, and compared with manual scraper unloading, the device is
safer and more efficient; a first scraper blade, a second scraper blade and a third scraper blade are arranged in a scraper
assembly, and the length of the first scraper blade is less than that of the second scraper blade, and the length of the second scraper blade is less than that of the third scraper blade, so that the effect of grading treatment is achieved, and the unloading is more complete without any residual material; an elastic scraper fixing mechanism is arranged in the scraper
assembly, and the first scraper blade, the second scraper blade and the third scraper blade are all installed in a scraper mounting groove through the elastic scraper fixing mechanism, so that the scraper blade is protected and the side wall of the
rotating drum is not damaged by scraping.
