Abstract

The invention relates to the technical field of potassium chloride purification, and discloses a three-in-one filter press for potassium chloride purification based on cyclic soaking; when the filter press lamination is unfolded, the filter cake is torn through the sawtooth-shaped insection on the tearing block, the friction among the spherical particles can generate vibration, the vibration can promote the loosening of the filter cake, meanwhile, the electric telescopic rod pushes the lifting moving block to move along with the expansion of the interval among the filter press lamination, at the moment, the connecting cable is slowly changed into a horizontal inclined form from a vertical inclined form to cut the filter cake, in the cutting process, the connecting cable can pull the moving frame to irregularly vibrate at the moment, the scattering of the filter cake is promoted, when the lifting moving block is at the farthest distance, the distance among the filter press lamination can be further enlarged, the moving frame horizontally moves under the action of the traction force of the connecting cable until the moving frame and the sealing layer are positioned on the same plane, and the filter cake is pushed away from the filter press lamination.
