Abstract
A filter press tray separating device has a latch and a pawl for engaging neighboring plates to be separated from the end of a pack of plates and means for separating the pawl from the latch while they engage respectively the end and next-to-end plates of the pack so that the separating force exerted by the pawl on the end plate is matched by an opposite reactive force exerted by the latch on the next-to-end plate, the device including means for disengaging the latch and pawl when a plate has been separated and for repositioning it at the next pair of plates to be separated. The latch and the pawl are both carried by a movable carriage means that moves along a stationary frame that extends along the longitudinal axis of the pack of plates.
Claims3
In a multiplate filter press having a stationary frame which extends along the longitudinal axis of a pack of filter plates mounted thereon and a filter plate separating device, wherein the improvement comprises:
- said filter plate separating device including a carriage being movably mounted to said frame for movement along said stationary frame in the direction of the longitudinal axis of the pack of filter plates,
- a latch carried by the carriage for engaging a filter plate adjacent to the filter plate to be separated from the pack,
- a pawl for engaging the filter plate to be separated from the pack, and
- separating means being movably mounted on the carriage, the pawl being mounted on the separating means, and the separating means including means for moving it with respect to the carriage for moving the pawl away from the latch and for separating the filter plate to be separated from the pack.
