A rotary drum filter has a plurality of longitudinally extending division grids mounted about the outer circumference of a drum. A plurality of corrugated sheets are provided, with the leading and trailing edges of each sheet mounted to circumferentially adjacent pairs of division grids to define filtrate compartments. An equivalent number of perforated filter plates are also provided. Each filter plate is attached to the top of a corrugated sheet and has a leading edge and a trailing edge that are set back from the leading edge and trailing edge of the corrugated sheet. A seal clip is positioned near the leading edge of each corrugated sheet. A seal member or seal members is/are held in place by the seal clip and is/are positioned at the face of the leading edge of each corrugated sheet or beneath and near the face or each corrugated sheet. A perforated cap strip can be removably attached to the top of each division grid to thereby retain for confined movement each filter plate and corrugated sheet combination (filter deck and drainage deck) during rotary drum filter operation and to allow easy replacement of the filter plate and corrugated sheet combination(s) and/or cap strip(s) when the rotary drum filter is not in operation. This rotary drum filter design and operation has increased capacity and efficiency.

High capacity and high efficiency filter deck assembly system and method of use and replacement

A continuous heat set line for setting yarn, having spaced-apart, elongate, tubular entrance and exit cooling chambers interconnected by an elongate intermediate steam heat-setting chamber communicating therewith. The entrance and exit cooling chambers and the intermediate heat-setting chamber collectively define a single longitudinally-extending axis along the combined length thereof. Sealing heads seal the entrance and exit cooling chambers and the intermediate heat-setting chamber to a degree sufficient to maintain a pressurized condition within the heat-setting chamber. A yarn conveyor extends through the pretreatment chamber for conveying the yarn through the entrance and exit cooling chambers and the heat-setting chamber. At least one piston and cylinder assembly moves sealing rolls into and out of position relative to each other, while independently-operating springs urge the rolls together sufficiently to effect a seal.
