DEAD BED PROTECTIVE SLEEVE FOR USE IN PROCESSING TACONITE

摘要

To minimize the amount of wear at the outlet or discharge pipe in the bottom of a tank or box through which a liquid or slurry containing abrasive particles flows, such as in the processing of taconite, a dead bed protective sleeve of a material having abrasion-resistant properties is employed, the sleeve having a flange that overlies the bottom of the box circumjacent the outlet pipe and also having a cylindrical portion depending downwardly into the outlet pipe. The flange functions as a dam or baffle so that the particles build up therearound to provide a cushioning effect which protects the bottom of the box in this region. The joint where the outlet pipe is connected to the box is also protected. Still further, the upper portion of the outlet pipe where turbulent action occurs is protected by the depending cylindrical portion of my sleeve.
