SEALING STRUCTURE OF FILTER AND CERAMIC MEMBRANE FILTER

摘要

PURPOSE: To enable the easy removal of a ceramic membrane filter out of a permeation device without the failure thereof and the assembly thereof into the device by sealing both end faces of the ceramic membrane filter with coating films and providing annular moldings made of a thermoplastic resin so as to cover the edges of the end faces thereof. ;CONSTITUTION: Both end faces in the longitudinal direction of the ceramic membrane filter 1 formed to a circular columnar shape, etc., at the outer contours are sealed with the coating films 2. The annular moldings 3 made of the thermoplastic resin are further fixed to both ends in the longitudinal direction of the ceramic membrane filter 1. The annular molding 3 on one end side of the ceramic membrane filter 1 is inserted and fixed into the recessed part 6d of a first cap 6 at the time of mounting the ceramic film filter 1. A first, sealing member 4A is fixed to the spacing between the flange 6b of the cap 6 and the annular molding 3 and the other end thereof is formed similarly. The ceramic membrane filter is thus easily mounted and removed and the edges 1c thereof are coated and protected.;COPYRIGHT: (C)1994,JPO&Japio
