Abstract

A delivery system deposits granular material being pneumatically conveyed within an entraining airflow to sequentially fill a storage silo from bottom to top. The delivery system has a series of vertical tubes and separators, vertically suspended and centered within the silo by a support, for conveying the entrained material upwardly from the bottom to the top of the silo. Each separator selectively separates the material from the airflow by choking the airflow entraining the material therewithin. Each separator automatically selects either to separate the entrained material therewithin and to deposit the separated material therefrom, or else to flow therethrough the entrained material without separation. The support has clamp assemblies, each having clamp halves and clamp brackets, wall brackets, and braces.
