PROBLEM TO BE SOLVED: To provide an opening plate method of a filter press which can easily release engagement between a stopper receiving a reaction force of filter plates and a rail.SOLUTION: In an opening plate method of a filter press, a stopper 5 at an end part of filter plates 4 is moved to the filter plate side and the filter plates slidably arranged in parallel are closed, the stopper is engaged with a rail 3, a fastening device 11 is extended to press a movable head 6 disposed between the filter plates and the stopper, and an undiluted solution is pressed in therebetween. Thereafter, the fastening device is contracted using an engagement blocking regression of the movable head so that the stopper is moved to the closed plate side, the fastening device is extended so that the movable head is moved to the closed plate side, and locks 15, 20 are received while engagement parts of the stopper and the movable head are separated. Therefore, the locks are easily released without damaging the engagement devices. |
