Sealing frames of adjacent filter press cells - against solids entry by resilient strips projecting from recesses in frame surface

摘要

The elements defining filter chambers in a press and disposed at both faces of a fixed support wall include thick frame edges from which project shaped resilient pressure walls against which a filter element is applied; a chamber for pressure medium results between the pressure wall and the fixed support wall. Recesses formed in the wall of the thick frame edges, immediately adjacent the filter chambers, hold resilient sealing strips whose outer surface, generally parallel to the frame edge, projects slightly beyond the frame edge in the direction of the set of press elements, and thus squeezes against the corresp. sealing strip in the next filter unit. The strip may carry an external compressible bead. ADVANTAGE - Prevents passage of solids into gap between adjacent frame edges, which could cause complications.
