EXTRACTION COLUMN PROVIDED WITH A SYSTEM FOR FAST MOUNTING, REPLACING AND DISMOUNTING THE SHAFT ELEMENTS

摘要

PURPOSE: An extraction column is provided which is useful for extractioncolumns using solvent. CONSTITUTION: An extraction column is provided with a practical and fast system for mounting, replacing and dismounting the elements of the shaft(2) of the upperdecanter(18) and of the lower decanter(19). The intermediate parts(14) are mounted on fixing means(10) resilient with respect to the support(1). The different elements of the extraction column are mounted on these intermediate parts, compressed by fixing screws(26) placed at the top of the column. The unscrewing of these screws(26) enables, by means of the spring-back(10), the unscrewing of each constituent elements and its quick replacement, without specific tools.
