ABSTRACT:
A perpendicular-standing rotary filter for the continuous separation of coarse particles from a suspension. The rotary filter has an upper part which includes a cylindrical filter basket disposed centrally in a cylindrical jacket. A chamber for the filtered material is formed by the space between the cylindrical jacket and the filter jacket of the filter basket. At least one centrally-located rotable scraper is continuously forced by means of a compression spring against the filter jacket. The rotary filter also has a lower part which includes a sump chamber in which at least one rotable stirring sheet is centrally disposed and which continuously presents (or always contains) one outlet for the filtered material and one outlet for the separated material. Preferably at least three scrapers are disposed in the filter basket. Also, preferably at least three stirring sheets are disposed in the sump chamber. The rotary filter can be a pressure filter.
