Abstract:
An apparatus for removing deposits from a pipe, comprising:a reversible drive means; a drive screw having a longitudinal axis, said drive screw located adjacent to an exterior surface of the pipe such that a longitudinal axis of the pipe and the longitudinal axis of the drive screw are substantially parallel, said drive screw rotatably attached to said drive means; a ball nut that is translatably affixed to said drive screw, said drive having an anti-rotation means for limiting the rotation of the ball nut in conjunction with rotation of the ball screw; a first tube that is connected with said reversible drive means and capable of being magnetized, said tube adapted to be translated over an outer surface of the pipe and having a longitudinal axis that is substantially parallel to the longitudinal axis of the pipe; and a second tube that is adapted to be translatably positioned on the interior of the pipe and capable of being magnetized and to be magnetically attracted to said first tube having an outer diameter adapted to permit said second tube to be positioned inside the pipe such that an exterior surface of the second tube is adjacent an interior surface of the pipe, and having a longitudinal axis that is substantially parallel to the longitudinal axis of the pipe.
