    摘要: A rotary drum vacuum precoat filter equipped so that the liquid level therein may be controllably varied to completely submerge the drum for precoating, followed by exposure of only a small part of the drum (not more than 30 percent) for cake drying and removal during filtration. There is also disclosed a scraper assembly for cake removal from the exposed drum just prior to resubmergence.
