Sieve for perfect separation of powder particles or liquids in industry, has evacuation chute integrated into support frame of sieve for evacuation of particles whose size is greater than vacuum mesh

摘要

The sieve (A) has a frame (D) and an evacuation chute (B) integrated into a support frame (C) of the sieve for evacuation of particles whose size is greater than a vacuum mesh, where the sieve acts as a single part with surface continuity, without any seal between the frame and the evacuation chute. An ultrasound excitation system is mounted on the sieve, where the continuous surface between the chute and the frame allows flow of particles without retention zone or loss.
