<p>A self-cleaning filter for a particulate-laden gas stream. A circular filter surface is positioned in the gas stream exhaust and includes a centrally mounted drive train. An elongate rotor transverses the face of the filter surface and is centrally coupled by a flexible joint to the drive train for rotative drive. Wheels mounted on each end of the rotor engage a circular track at the periphery of the filter surface; one wheel is spring biased to continually force the wheel at the opposite end of the rotor against the track. A vacuum cleaning head is associated with the arm of the rotor opposite the spring biased wheel to remove particulate matter collected on the filter surface.</p> |
