Title:
FILTER APPARATUS FOR POLYMERS
Document Type and Number:
WIPO Patent Application WO/1985/002553
Kind Code:
A1
Abstract:
A polymer filtering apparatus includes a polymer pipe (12, 112) having a multiplicity of through-holes formed in its peripheral surface, and leaf filters (13, 113) and support members (14, 14a, 114, 114a) which are detachably and alternately laminated one upon another around the polymer pipe. Each leaf filter has a pair of filter members (21, 121) made of a filter medium which cannot bear filtering pressure. On the other hand, each support member has polymer-permeable support plates (25, 25a, 125, 125a) which respectively contact the filter members of the adjacent leaf filters from the outside thereof such as to support the filter members against filtering pressure. Thus, a polymer is filtered by passing from the inside to the outside of each leaf filter through the filter members and the support members. The leaf filters and the support members can be removed from the polymer pipe and, therefore, it is possible to wash them independently of each other.
