<p>A device for use in combination with a plate-type liquid filter apparatus for extracting sheets of filter media (14) from between adjacent plates (12) is disclosed. The device comprises a series of horizontal trays (18) connected to a frame (16) and adapted to support sheets of filter media (14) extending from an adjacent multi-plate filter apparatus. A contact bar (24) is provided for and extends transversely to each sheet. All contact bars are connected at their opposite ends to a pair of vertical drive bars (26) which are attached to drive chains (28, 30) that move the drive bars (26) in a generally rectangular path so that the contact bars (24) are first moved downward in unison to make frictional contact with the media sheets (14), then forwardly to move the sheets along on their support trays (18), then upwardly out of contact and back to the starting point on each extraction cycle.</p> |
