Filter assembly with dynamic filter media

摘要

A filter assembly for removing particles from air flow across the filter assembly with a frame around a perimeter of the filter assembly, dynamic filter media for removing particles from air flowing from an upstream side of the filter assembly to a downstream side of the filter assembly that passes from a clean filter media storage chamber to a used filter media collection chamber within the frame on a second side of the filter assembly. The dynamic filter media is moved from the output from a turbine shaft modified by a gearbox to drive a set of drive traction rollers.

1. A filter assembly for removing particles from air flow across the filter assembly, the filter assembly comprising:
a frame around a perimeter of the filter assembly; a quantity of dynamic filter media for removing particles from air flowing from an upstream side of the filter assembly to a downstream side of the filter assembly; a clean filter media storage chamber on a first side of the filter assembly; a used filter media collection chamber within the frame on a second side of the filter assembly, opposite from the first side; a turbine which spins from air flow traveling from the upstream side of the filter assembly to the downstream side of the filter assembly; a gearbox receiving torque input from the turbine, the gearbox drives the dynamic filter media across the upstream side of the filter assembly and deposits dynamic filter media after use into the used filter media collection chamber; and wherein a speed that dynamic media is moved into the used filter media collection chamber is dependent on a rate of air flow and largely independent of a length of time that the filter assembly has been in service.
