[0004] When the plate-and-frame filter press is used, the movable end plate and the filter plate are pushed towards the fixed end plate by the hydraulic jack, the movable end plate and the fixed end plate press the filter plate, then sludge is conveyed to the filter plate, the solid mud cake is formed between the filter plates, after the filter pressing is completed, the hydraulic jack is reset, then the filter plates are moved one by one, so that the filter plates move towards the movable end plate, and when the filter plates are moved by the push plate trolley, the mud cake on the filter plates is naturally unloaded under the action of gravity. However, the mud cake has certain adhesion, and is attached to the filter plate, so it is difficult to completely separate the mud cake from the filter plate by relying on gravity alone. In view of this, a filter press device for sludge treatment is needed to be designed to completely separate the mud cake from the filter plate. UTILITY MODEL CONTENTS

Then the second linear movement mechanism runs, driving the third linear movement mechanism and the gripper to approach the support rod. The gripper grips the support rod, and the movable end of the third linear movement mechanism drives the gripper to move up and down. When the filter press plate moves downward, it collides with the support slide plate, and then moves upward. This process is repeated to make the filter press plate shake, shaking the filter cake off the filter press plate and completely separating the two. After the filter cake is separated from the filter press plate, the gripper remains connected to the filter press plate. The first linear mechanism drives the filter press plate to move towards the moving end plate of the plate and frame filter press body. Then the second linear movement mechanism is reset, and the gripper separates from the support rod. Attached Figure Description
