Horizontally mounted cylindrical segmented bore pleated filter system for rotary broom sweepers

摘要

Disclosed is an air filtration system having a horizontally mounted cylindrical filter element. The sytem includes a clean air plenum having a substantially vertical wall with an inlet opening formed therein. A draw bar is supported at the center of the plenum inlet and extends horizontally away from the plenum. A partition member is mounted on the draw bar and includes a plurality of elongated radially extending partition panels. A cylindrical filter element is supported on the partition panels with the partition panels dividing the bore of the filter into a plurality of segments. An end plate is connected to the draw bar to engage the filter element. A reverse air discharge system is disposed in the plenum for discharging jets of pressure air to backflush the filter segments. An elongated diverter element extends substantially parallel and in close proximity to the upper surface of the filter element.
