Filter bag securing for disc filter, comprises passing elastic loop through channel formed in collar around neck opening in bag

摘要

A filter bag has a collar around its neck opening which contains a channel for receiving a loop made from an elastic material. After the neck opening has been tightened around the segment neck, the loop is passed through the channel in the collar. Securing a filter bag to a disc filter comprising a number of substantially triangular-shaped segments with a wide end at the disc periphery and a narrow end located in the disc frame comprises: (a) a filter bag is used which has a neck opening surrounded by a collar having a thickness significantly greater than the thickness of the filter material; (b) the filter bag is pulled over a segment via at least one mounting opening in the bag; (c) the mounting opening is closed; (d) the neck opening is tightened against the segment neck using at least one fastener device; (e) at least one channel extending around the neck opening is formed in the collar; and (f) a loop made from elastic material is passed around the neck opening via the channel in the collar.
