  • Self-limiting vacuum nozzle and methods for using same
    Patent number: 9089882
    Abstract: A self-limiting vacuum (SLV) nozzle is provided for collecting or removing combustible dust. The nozzle comprises a nozzle body comprising a nozzle inlet port, a nozzle unloader port, and a suction port; a suction tube assembly operably connected to the nozzle inlet port; a material deflector for directing vacuumed material from the suction tube assembly into the suction port; and an unloader hood installed in the unloader port. Discs can be installed in the unloader or suction port to control collection of combustible dust by the nozzle so that the concentration of dust collected within the hose stays below the minimum explosive concentration (MEC). The nozzle is operably connected to a vacuum source. Systems and methods for collecting combustible dust using the nozzle and a vacuum system are provided. Operation of the nozzle regulates the MEC of the combustible dust that is collected in the vacuum system.
