ABSTRACT:
An apparatus and a method for cleaning a conduit that has unwanted chemical substances deposited on an interior wall of the conduit are provided. The apparatus utilizes a rack-and-pinion drive mechanism for moving a set of cleaning blades in a rotational motion such that the blades may be driven more reliably and more accurately. The rack-and-pinion drive mechanism further allows the set of cleaning blades to scrape off chemical substances in two directions, i.e., when the pinion gear is rotated either clockwise or counterclockwise. The present invention novel apparatus further provides the alternative of having a second set of blades mounted below the main set of cleaning blades such that a second conduit section situated below the conduit may also be cleaned.
