PROBLEM TO BE SOLVED: To provide a device for improving the reliability of judgement whether tightening with tightening means is suitably switched to reaction reception with reaction receiving means upon tightening.SOLUTION: A filter press device has tightening means 51, disposed between a loose head 4, disposed outside of a filter plate present at one end side of a group of filter plates 3 made extendable/contractable and openable/closable in the thickness direction of the filter plates 3 and constituted of a plurality of filter plates, and a reaction seat body to tighten the group of filter plates by moving the loose head 4 in the thickness direction of the filter plates 3, reaction force receiving means 52 that receives reaction force causing the loose head 4 to move in the opposite direction of the tightening direction upon compression at a position of the receiving head moved in the thickness direction of the filter plates 3, and measurement means that measures the travel of the loose head 4, and is configured to stop operation or retighten with the tightening means 51 when the travel of the loose head 4 the measurement means has measured is over a specified value at the stage where the tightening with the tightening means 51 is switched to reaction force receiving with the reaction force receiving means 52.SELECTED DRAWING: Figure 3 |
