ABSTRACT:
A limp, porous membrane (18) is formed from a flexible sheet material (20). The membrane is used with a fluidized hopper outlet (10) containing a pulverant, particulate lading which is fluidized and unloaded via the outlet. A valve installed in the outlet, when open, extends substantially through the outlet and allows fluidized lading to be unloaded through the outlet. The outlet has a frame (12) for securing the outlet to the hopper, an outlet opening (14) in which the valve is positioned, and intersecting outlet walls (16) extending between the frame and the opening. An outer margin (54) of the membrane is secured to the frame. An inner margin (18) of the membrane, which defines an opening for the lading, is attached to a boot (36). The boot is secured to the top of an outlet pan (P), adjacent the outlet opening, by a retainer ring (50). The ring locks the boot in place so the opening in membrane is secured adjacent to the outlet opening for the lading to flow into the outlet through the valve.
