Latest Patents

One of Gregory's latest patents is titled "Air-assist discharge of filter press cake." This invention features a filter press plate shifter assembly designed with a shifting housing that has a tunnel-like center part. This part passes over the filter plates and housing components positioned adjacent to opposite side rails. The housing parts are rollingly supported on rods extending along the side rails. One housing part is equipped with a rotary pneumatic motor and a drive roller that engages the rod to control the movement of the shifter assembly along the press. Each side housing part includes a pneumatic plate shifter, allowing the endmost plate in the closed stack to be individually and sequentially shifted away from the stack when discharge of filtrate is desired. The shifter housing also mounts a bumping device that cooperates with the endmost plate to effect vertical bumping, assisting in loosening sticky cake adhering to the plate. Additionally, the air-assist discharge mechanism includes a nozzle-bearing head assembly that moves vertically downward between adjacent plates, discharging pressurized airstreams to help remove the sticky cake. The overall operation of the shifter assembly is fully automated, enabling efficient discharge of sticky cake from the filter press.
