METHOD OF, AND APPARATUS FOR, FILTERING A SLURRY |
摘要 |
Filter cake formed from a slurry is dried in a filter press comprising a plurality of filtration units each having a chamber bounded by a pair of opposed flexible walls with at least one of said walls being constituted by a filter medium. The flexible walls are sandwiched between flexible membranes. The filter cake is formed and compressed in the chambers by hydraulic fluid pressure acting on the flexible membranes. By means of pressure oscillations set up in the hydraulic fluid, the filter cake in the chambers is deformed by bowing from side to side of an initial central plane, whereby drying is improved. |
