Filter deck assembly sliding seal

A deck assembly for a rotary drum filter having a drum mounted for rotation, comprising:

• a plurality of longitudinally extending division grids mounted and spaced in parallel relationship about the outer circumferential surface of the drum;
• a plurality of corrugated sheets each sheet having alternating ridges and channels extending from a leading edge to a trailing edge, the leading and trailing edges of each sheet mounted on adjacent pairs of division grids to define filtrate compartments around the circumference of the drum;
• drainage slots near the trailing edge of each channel for communication to said compartments;
• a plurality of perforated filter plates, each filter plate attached to the top of a corresponding corrugated sheet and having a leading edge that is set back from the leading edge of the correponding corrugated sheet;
• and an "L" shaped seal member having a first leg engaged between the leading edge of the filter plate and the adjacent corrugated sheet;
• and
• a second leg sealingly abutting the leading edge of said corrugated sheet.

• a seal member disposed at the leading edge of each corrugated sheet and having a first leg engaged between the filter plate and the corrugated sheet;
• shoulder portions on both longitudinal faces of each division grid adapted to slidably mount respective leading and trailing edges of circumferentially adjacent corrugated sheets;
• and further comprising;
• and
• a longitudinally extending cap strip which is fixed to the division grid so as to overlap the leading and trailing edges of the adjacent corrugated sheets.
