ABSTRACT:
Disclosed are a filter cake scraping method which can scrape a filter cake layer deposited on the surface of a filter drum with a scrape blade even if the particles of the cake are fine, and a rotary drum filter using this method. When pressure inside a suspension vessel rises above a predetermined value, a control means quickly reduces the pressure. Accordingly, precoated material or the like, which has been deposited on the filter drum, expands to push a layer of filter cake outward, thus permitting a scrape blade provided beside the filter drum to scrape the expanded cake layer.
