  • Vacuum device for collecting light and heavy material
    Patent number: 9874225
    Abstract: A vacuum device has a motor-driven blower wheel with suction side and with pressure side with pressure channel and blow-out opening. An intake pipe at the suction side has an intake opening and a discharge opening at opposed ends. The intake pipe conveys a suction airflow entraining first and second collected materials. Through the discharge opening the first collected material is discharged from the intake pipe. A blower inlet opening is formed in a wall of the intake pipe. Blower inlet opening, blower wheel, and pressure channel are configured such that second collected material passes through blower inlet opening and blower wheel into the pressure channel for discharge through blow-out opening. The blower inlet opening, in longitudinal direction of the intake pipe, is positioned between discharge opening and intake opening at a first spacing to the intake opening and at a second spacing to the discharge opening.
