<p>Method and apparatus for cleaning a chamber (25) is disclosed. Scraping blades (65) are rotatably mounted within a chamber (25) and parallel to a longitudinal axis of the chamber (25). The scraping blades (65) are rotated circumferentially within the chamber (25), scraping the inner surface (26) of the chamber (25) to prevent the buildup of particulate matter. An annular gear assembly provides mounting support for the scraping blades (65). A pneumatically operated pushrod assembly (85) rotates the scraping blades (65) circumferentially within the chamber (25). The annular gear assembly and pushrod assembly do not obstruct a direct path through the chamber (25).</p> |
