Latest Patents

One of Joel'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. A rotary pneumatic motor and a drive roller are mounted on one housing part, which engages the rod to control the movement of the shifter assembly along the press. Each side housing part is equipped with a pneumatic plate shifter that allows for 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 includes a bumping device that cooperates with the endmost plate to effect vertical bumping, assisting in loosening sticky cake that adheres to the plate. Additionally, an air-assist discharge mechanism is incorporated, featuring a nozzle-bearing head assembly that moves vertically downward between adjacent plates to discharge pressurized airstreams, aiding in the removal of sticky cake. The entire operation of the shifter assembly is automated, allowing for efficient discharge of sticky cake from the plates.
