Abstract
A method for temporary storage of granular material in a receiver having a horizontally elongated chamber within a housing, the chamber having a convex triangular cross-section and a dump flap defining a bottom vertex of the triangular cross-section, with a horizontal air/vacuum resin material inlet connecting to the chamber, and a horizontal air/vacuum outlet leading from and connected to the chamber.
Claims4
A method for temporary storage of granular material prior to processing thereof into a finished or semi-finished product, comprising,
- a) feeding an air/vacuum stream carrying the granular material into a chamber under vacuum;
- b) reducing velocity of the stream in the chamber thereby causing granular material entrained in the stream to fall to the chamber bottom;
- c) continuing drawing the stream from the chamber thereby maintaining vacuum in the chamber;
- d) releasing the vacuum horizontally from the chamber thereby allowing a bottom of the chamber to swing to an open position, in response to granular material resting thereon.
A method for temporary storage of granular material prior to processing thereof into a finished or semi-finished product, comprising:
- a) drawing a vacuum stream carrying granular material in a transport conduit to a chamber, the chamber having cross-sectional area larger than that of the conduit;
- b) introducing the vacuum stream into the chamber thereby
- i) causing speed of the vacuum stream to decrease and causing the carried granular material to drop to the bottom of the chamber;
- and
- ii) closing the chamber bottom as the vacuum acts to provide force on a chamber movable bottom member;
- c) maintaining the chamber bottom closed by continuing to draw vacuum in the chamber;
- d) releasing vacuum from the chamber thereby allowing the movable bottom member to open in response to weight of granular material resting thereon thereby permitting gravity induced flow of granular material downward out of the chamber.
