ABSTRACT:
A vacuum receiver for use in a pneumatic vacuum conveying system having a lid which gas-tightly closes a particle storage vessel. The lid has two apertures therein allowing a gas-particle stream to enter the interior of the vessel and a gas stream to exit the vessel. An upstanding hollow inlet housing is gas-tightly secured on an exterior surface of the lid communicating with one of the apertures. An inlet port is provided in one side of the inlet housing. The gas-particle stream enters the inlet port with sufficient velocity so that the particles strike the inlet housing opposite the inlet port to decelerate the particles. The particles fall through the one aperture and are stored in the vessel. The gas stream also enters the vessel through the one aperture and exits through the other aperture into an upstanding hollow outlet housing. The gas stream exits the outlet housing via an outlet port in the outlet housing. The outlet port is selectively closable by a plunger with a stopper plate thereon housed within the interior of the outlet housing. When the outlet port is closed, no gas-particle stream enters the vacuum receiver.
