Abstract
A filter sub for a wellbore drilling system includes a filter having an uphole end for receiving a drilling fluid, and a downhole end opposite the uphole end, the filter defining a plurality of apertures through which the drilling fluid flows out of the filter, each aperture exhibiting a size that retains debris of a predetermined size within the filter, and a flapper pivotably attached to the filter at the downhole end with an actuatable hinge. The flapper is pivotable at the actuatable hinge between a closed position, where the flapper occludes the downhole end and thereby prevents debris accumulated within the filter from escaping the filter, and an open position, where the flapper exposes the downhole end and thereby allows the debris to escape the filter and be discharged from the filter sub.
