Abstract
Elevating and conveying system and method for unloading vessels, or the like, comprising: a vertical pneumatic pipe having a lower end adapted for being positioned in the particulate material to be removed from the vessel, or the like; an approximately horizontal conveyor; a joining chamber between the horizontal conveyor and the vertical pipe; the vertical pipe has a smaller cross-sectional area and the horizontal pipe has a larger cross-sectional area, such that material suctioned up the vertical pipe will settle out from the air flow as it moves into the horizontal pipe; the joining chamber is enlarged for reducing air flow velocity and redirecting the flow of air and material; a conveyor means in the horizontal conveyor, such as a fluidizing conveyor, a mechanical conveyor, or the like.
