Pneumatic vacuum separation plant for bulk materials

摘要

A system for density-based particle separation includes a loading bin, a separating feeder, a mesh conveyor belt, a compressor for the mesh conveyor belt, transporting nozzles integrated with the separation bins and located over the mesh conveyor belt, discharge nozzles positioned under the mesh conveyor belt in the same plane with transporting nozzles and adjusted for separation of the primary material into particle products of specific density and an aspiration systems (cyclones), as well as fans for generation of ascending sucking air flows in the transporting nozzles and discharge flows in the discharge nozzles.

1. A pneumatic vacuum density-based particle separation system comprising:
a loading bin for receiving a loose substrate; a separating feeder for feeding separated particles of the loose substrate, the separating feeder having a finned surface with slots positioned lengthwise for removal of the plate-shaped particles from the loose substrate; a mesh conveyor belt; an air compressor blowing air through the mesh conveyor belt; transporting nozzles integrated with pyramidal-shaped separation bins and located over the mesh conveyor belt at different distances from the mesh conveyor belt; discharge nozzles located under the mesh conveyor belt in the same plane as the transporting nozzles and under the transporting nozzles at different vertically adjustable distances from the mesh conveyor belt, wherein the discharge nozzles and the transporting nozzles are simultaneously adjusted for separation of the primary substrate mixture into particles of specific density; a plurality of aspiration cyclones that connect the transporting nozzles to suction devices that generate pre-set velocity and lifting power of an air flow; fans for generation of ascending laminar suction air flows in the transporting nozzles; and a discharge flow generator in each of the discharge nozzles; wherein the transporting and discharge nozzles move along the mesh conveyor belt and the discharge nozzles are connected directly to the discharge flow generators.
