The working principle of the invention is as follows: the press 105 drives the pressing plate 106 to push the plate frame members 201 movably mounted on the side rail plate 107 to be tightly attached to each other, a complete filter chamber is formed between the pressing films 205 mounted on the adjacent plate frame members 201, at this time, the slurry pump 110 injects slurry stored in the slurry tank 111 into the complete filter chamber formed by the pressing films 205 through the grouting pipe 109, the next complete filter chamber is sequentially filled with slurry through the aligned central pipe 206 after the first filter chamber is filled with slurry, after the injection is completed, the slurry starts to be dehydrated for the first time under the effect of pressure, filtered water is injected into the filtrate holes 202 through the liquid guide grooves 203 at four corners of the pressing films 205, the filtrate holes 202 are attached to each other to form a filtered water channel, filtered water flows in from the channel and is discharged outwards from the liquid discharge pipe 108, then the air pump 209 injects air into the air pipe 211 through the connecting pipe 212, the high-pressure air flow is injected into the inside the plate frame members 201 through the hose 213 and the air injection holes 204 connected with the hose 213, the high-pressure air flow enters the channel inside of the vortex extending channel 214 through the air injection hole 204 at first, so that the movable block 216 is pushed to move inside the channel of the vortex extending channel 214 and finally moves to the limit bent end 215 to stop in a limit mode, when the movable block 216 moves, the cams 222 arranged on the movable block roll the pressing films 205 on two sides respectively, when rolling, the continuously-rolling cams 222 locally press mud in the filter chamber, along with the injection of the high-pressure air flow, when the movable block 216 stops moving, the high-pressure air flow is injected into the inner space of the plate frame 201 through the pressure release valve 223, the pressing films 205 start to expand outwards, the adjacent formed complete filter chambers start to compress, mud at the position starts to be dehydrated for the second time, the filtrate is discharged into the water filtering channel formed by the filtrate hole 202, after the pressure filtration of the mud is completed, the separation between the adjacent plate frame 201 starts, the filter cake that the filter-pressing produced drops from here, still have some mud piece to adhere to press film 205 surface after the filter cake drops, close air pump 209 this moment, high pressure air flow stops to pour into, movable block 216 is reset by the effect of reset soft spring 217, movable block 216 moves to the beginning end of vortex form extension passageway 214 from spacing curved end 215, the cam 222 of this in-process both sides constantly rolls, make the both sides press film 205 surface that contacts with it produce the shake effect, thereby shake off the partial mud piece that adheres to, prevent that the mud piece from producing adverse effect to subsequent filter-pressing, realize the secondary shake off effect to the mud piece through this mode, filter water is discharged from fluid-discharge tube 108 back and is got into filter frame 302, tiny mud impurity that carries in the filter water can be filtered by filter plate 303, the filter water after the secondary filtration can outwards be discharged from drain pipe 305, realize the secondary filter effect to the filter water through this mode of device, after accomplishing the work, servo motor 405 drive 404 rotation, thereby, the rotation drive post sleeve 406 moves forward 411, thereby can make the movable block 412 to make the inclined plane contact with the movable block, thereby change the leading to change to the position to the filter cake piece to change to the appropriate side plug-press piece to the frame 410, thereby make the filter cake piece is changed to the frame is moved to the place to the control the side plug-down to the adjacent to the motion piece, can make the frame 201 and make the change and make the frame 201 and change and make and change and can make and change to the position to the appropriate to the frame to the appropriate side of the frame piece to change and make it to the side of the piece to be used.
