Material separator for a vertical pneumatic system

摘要

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 for conveying the entrained material upwardly from the bottom to the top of the silo. Each separator automatically selectively either separates the entrained material, by choking the airflow entraining the material within an outlet tube thereof, and automatically deposits the separated material through an outlet thereof; or else flows therethrough the entrained material without separation. A support system comprises a vertical support that vertically suspends and centers the delivery system within the silo and reinforces the silo, and a horizontal support that selectively supports the delivery system upon the silo floor.

1. A method of delivering material being transported by a conveyor entraining the material within a flow of fluid, wherein said method comprises:
flowing the fluid flow entraining the material into a separator, comprising an inlet, an outlet tube, at least a wall for interconnecting the inlet and the outlet tube, a through aperture between the wall and the outlet tube, and an outlet, through the inlet thereof, wherein the separator, the inlet, the outlet, the through aperture, and the outlet tube are coaxial, and wherein the inlet, the outlet, and essentially entirely the wall are on a proximal side of the through aperture and essentially entirely the outlet tube is on a distal side of the through aperture; flowing at least a portion of the fluid flow entraining the material through the through aperture and within the outlet tube of the separator; separating the material from the fluid flow within the outlet tube of at least the portion of the fluid flow entraining the material therewithin, wherein said separating comprises choking the portion of the fluid flow entraining the material within the outlet tube of the separator; and depositing the material from said separating out of the separator through the outlet thereof.
