VENTURI INDUCER SYSTEM FOR TRANSFERRING MATERIAL

摘要

A continuous supply of scrap material from a papermaking or converting process is transferred by a venturi inducer system including a housing surrounding a tubular intake duct which defines with the housing an annular air chamber connected to receive pressurized air from a motor driven blower. The housing has a tapered or frusto-conical portion connected to a tapered material outlet duct and which cooperates with the inner end of the intake duct to define an annular nozzle opening. Long adjustable bolts connect the intake duct to the housing outboard of the housing and provide for externally adjusting the intake duct axially for precisely selecting the area of the nozzle opening to optimize the air flow through the nozzle opening for pulling and transferring the material while minimizing the electrical power required to operate the blower motor.
