A rotary filter drum in which the drum is a single cell having a perforated cylindrical wall and solid end walls. A hollow central shaft extends through the drum and its opposite ends extend axially from the end walls. The drum contains a plurality of relatively narrow elongated open-top pans that are equally spaced radially from and angularly about the central shaft. Each pan is defined by a bottom, spaced apart inner and outer sidewalls which extend the full length of the drum and the drum end walls. The pan walls are secured to the ends of the drum. The pans are located so the open tops face the direction of drum rotation and the entire leading edge of the outer sidewall of the pan is secured to the perforated cylindrical wall. A closed conduit connects the bottom portion of each pan to the central shaft which in turn connects to the vacuum source so the filtrate is removed from and vacuum applied to the interior of the drum solely through the central shaft but via the pans and connecting conduits.

Rotary vacuum filter

A vacuum disc filtering system is disclosed wherein each of the discs possesses a separate control for its vacuum, feed, drain and blow discharge. The filter discs are of one piece construction and divided into segments by means of grooved radial arms. The radial arms are adapted to receive a caulking media for holding a filter cloth on each of the segments. The filter disc is true running and any of the discs in a filter system may be operated separately and independently of the other discs.
