Abstract

Disclosed is an article and processes for cleaning rotatory kilns. The article is comprised of a long, rigid or flexible, rod or shaft which supports bristles or tines that extend outward, for example, perpendicularly, from the rod or shaft, for substantially the entire length of the rod or shaft; and one or both ends of the rod or shaft are adapted to receive mechanical rotational and lateral torque forces thereby transferring and producing abrasive forces between the bristles ends in contact with the interior of the rotary kiln chamber. The tines or bristles are constructed of a suitably strong and partially flexible material, such as metal wire or polyester. The cleaning process comprises inserting the article into a rotary kiln that has been soiled or fouled, for example, with synthetic or natural resin coating material; mechanical forces are applied to the rod member to provide agitation and abrasion force to the interior of the rotary kiln chamber, typically a hollow cylinder; and wherein debris adhering to the interior walls of the kiln chamber is loosened easily and removed continuously or batchwise therefrom by, for example, gravity, vacuum, or an air knife. Alternatively, the article can be locked into place at one or both ends and the kiln rotated to accomplish the same scraping and abrading action to liberate debris adhering to the interior walls of the kiln. The cleaning process can be accomplished when the kiln is either heated or cooled depending on the nature and the consistency of the material to be removed. In a related embodiment, a modified article can comprise a rod or shaft with a plate fitted perpendicularly to the axis of the rod at one end of the rod and the other end of the rod is attached to a rotary drive means, for example, a medium to high torque motor; and the plate has bristles or tines attached to one side of the plate and opposite where the rod is attached.
