SEALING MEMBER FOR A FILTER PRESS

摘要

The present invention relates to a sealing member preferably for sealing of the sides of the pressing zone of filter presses used in the pulp and paper industry. Previously known sealing members have been complicated. Most commonly they have been composed of sheet-formed rubber and supporting metal rods attached to each other with bolts. The users have not, however, been satisfied with such arrangements because the bolt attachment has not facilitated the structure of the sealing member remaining unchanged along the whole length of the press, but the sealing member has had to be left unsupported at the narrow end of the pressing zone, whereby it has often failed and let pulp be discharged to the press side. Furthermore, earlier seals have worn down very quickly. The sealing member according to the present invention solves the problems mentioned above because the sealing members (36, 38), made of practically permanent material which is ideal as to its friction properties relative to the wire surfaces, are constructed to form a single sealing member (30) together with the support members (32, 34), which sealing member (30) allows bending thereof conforming to the movements of the press wires, but prevents the tendency of the sealing member to bend, which tendency is caused by the pressure of pulp.
