FILTER DEVICE WITH SOLIDS CONVEYOR

摘要

Filtering devices wherein solid particulate matter is separated by filter media from a liquid flow often contain conveying means for moving the separated solid particulate to an external point for disposition. One such conveying means usable in filtering devices includes spaced endless chain loops wherein each chain comprises alternate center links pivotally joined by pins to alternate sets of spaced side bars. In each center link is an elongated aperture which in a controlled manner holds an extension bar attached to each end of a traversely positioned flight. The spaced chain may be operatively connected to a source of rotary power to periodically advance the conveying means so that the flights may be moved over a section of the filter media to effectively remove separated particulate matter collected thereon.
