EASILY REMOVABLE FLUID PERMEABLE STRUCTURE FOR AERATED HOPPER DISCHARGE OUTLETS

摘要

A fluid permeable member for an aerated hopper discharge outlet which may be easily inserted within and removed from the hopper discharge outlet. The fluid permeable member comprises a one-piece inner insert having a central discharge opening in vertical alignment with the discharge opening of the bottom discharge outlet and is easily secured in spaced relation to the outer lower housing or body of the discharge outlet by releasable securing means, such as threaded bolts. The inner fluid permeable insert is preferably formed of a stainless steel wire mesh material. The outer housing of the discharge outlet has an upper peripheral flange mating with a lower peripheral flange on the bottom of the hopper, and the fluid permeable member has a peripheral flange positioned and gripped between the mating flanges of the outer housing and the superjacent hopper.
