Ascension pipe and elbow cleaning apparatus

Abstract

An improved cleaning apparatus for the removal of carbonaceous deposits from the inner surfaces of the ascension pipe elbows and ascension pipe employed on coke ovens. The cleaning apparatus is comprised of a base support, a movable support and a cleaning element. The base support is mounted on a larry car and the movable support is superimposed upon and connected to the base support. The cleaning element is pivotally attached to the movable support and is equipped with a cleaning head mounted on the end of an arm and means for moving the arm in and out of the pipe which is to be cleaned. There is also provided means for adjusting the movable support in either a horizontal or a vertical position so that after the cleaning element has been initially aligned with the lateral leg of the elbow by moving the larry car and by moving the cleaning element on its pivotal connection with the movable support, the cleaning element may be universally further aligned so as to compensate for thermally caused misalignment in the ascension pipe elbow by adjusting the position of the movable support. In a preferred embodiment, means are provided to also move the cleaning element into initial alignment with the vertical leg of the elbow and with the ascension pipe itself and to adjust the position of the movable support so as to further align the cleaning element with these pipes. In this preferred embodiment, the arm of the cleaning element is also telescopically extendable.
