The hydraulic oil cylinder 6 drives the movable plate 3 to press the filter group 5 onto the fixed plate 2, so that the filter plates 51, the filter cloth 53 and the filter frames 52 are tightly attached to each other, and the filter plates 51, the filter cloth 53 and the filter frames 52 are connected in a sealing manner. The upper parts of the frames of the filter plates 51 and the filter frames 52 are respectively provided with a material liquid channel 54, and the material liquid channel 54 of the filter plate 51 and the material liquid channel 54 of the filter frame 52 are aligned with each other and can be in butt joint communication with each other. The frame of each filter frame 52 is provided with a feed hole 55 and a slide hole 57, the feed hole 55 is arranged below the material liquid channel 54, the slide hole 57 is arranged above the material liquid channel 54, the slide hole 57 is aligned with the feed hole 55, the central axis of the slide hole 57 coincides with the central axis of the feed hole 55, two ends of the feed hole 55 are respectively communicated with the material liquid channel 54 and the filter chamber, and two ends of the slide hole 57 are respectively communicated with the outer wall of the filter frame 52 and the material liquid channel 54. Feed liquid to be filtered and dehydrated is injected into all the filter chambers through the feed liquid channel 54 and the feed holes 55, and slurry is injected into each filter chamber along with the continuous injection of the feed liquid. The filter frame 52 is provided with a dredging component 7, the dredging component 7 dredges the feed hole 55 when the filter frame 52 is separated from the filter plate 51, and the dredging component 7 leaves the feed hole 55 when the filter frame 52 is attached to the filter plate 51.

When the filter plate 51 is jointed with the filter frame 52, one end of the dredging rod 71 penetrating through the feed hole 55 is contracted into the slide hole 57, and the return spring 73 is in a stretching state; when the filter plate 51 and the filter frame 52 are separated, the dredging rod 71 penetrates through the feed hole 55 under the action of the return spring 73, and the return spring 73 returns to a natural state. When the filter frame 52 is separated from the filter plate 51, the force applied to the push rod 72 is gradually reduced, and the push rod moves downwards under the force of the return spring 73 until the return spring 73 returns to the natural state. The return spring 73 generates elasticity by twisting, and can play a certain role in limiting the rotation of the dredging rod 71. When the filter plate 51 is attached to the filter frame 52, the push rod 72 is pushed by the filter plate 51 and the push plate 56 to rotate, the relative position between the end of the push rod 72 connected with the push plate 56 and the push plate 56 keeps unchanged, and the end of the push rod 72 connected with the dredging rod 71 moves upwards to drive the dredging rod 71 to move upwards until the filter plate 51 is attached to the filter frame 52.

After the push plate 56 and the filter plate 51 are separated from the push rod 72, the torsion spring can keep a certain angle between the push rod 72 and the dredging rod 71, so that the push rod 72 can drive the dredging rod 71 to move upwards when receiving the pushing force, and meanwhile, one end of the push rod 72, which is far away from the dredging rod 71, is always higher than the filter plate 51, and the situation that the joint of the filter plate 51 and the filter frame 52 is influenced because one end of the push rod 72, which is far away from the dredging rod 71, drops to a position lower than the upper end surface of the filter plate 51 is avoided.
Referring to fig. 4 and 5, the dredging rod 71 is in clearance fit with the sliding hole 57, the diameter of the sliding hole 57 is smaller than that of the feed hole 55, and the side wall of the feed liquid channel 54 connected with the sliding hole 57 is provided with a sealing plane which is arranged around the sliding hole 57. One end of the dredging rod 71 penetrating through the sliding hole 57 is connected with a sealing ring 74, the sealing ring 74 is in threaded connection with the dredging rod 71, the outer diameter of the sealing ring 74 is smaller than the diameter of the feeding hole 55 and larger than the diameter of the sliding hole 57, and the upper end face of the sealing ring 74 can be tightly attached to a sealing plane and seal the lower opening of the sliding hole 57, so that the feed liquid in the feed liquid channel 54 is prevented from entering the sliding hole 57. The sealing washer 75 that rubber was made is installed to the up end of sealing washer 74, and the rubber pad is fixed cohering on sealing washer 74 through the viscose, and sealing washer 75 is compressible, improves sealing performance of sealing washer 74. Because the push rod 72 is in contact with the filter plate 51 and slides relatively, the push rod 72 is in contact with the push plate 56 and slides relatively, the push rod 72, the filter plate 51 and the push plate 56 are abraded, after the filter plate 51 is attached to the filter frame 52, a gap exists between the sealing ring 74 and a sealing plane, so that the feed liquid enters the sliding hole 57 and leaks, the sealing gasket 75 can be kept to be attached to the sealing plane before the abrasion loss of the push rod 72, the push plate 56 and the filter plate 51 reaches a certain degree, the sealing performance of the lower end of the sliding hole 57 is improved, and the service lives of the push rod 72, the push plate 56 and the filter plate 51 are prolonged. In another embodiment, the end of the push rod 72 away from the dredging rod 71 is provided with a roller 77, the roller 77 is rotatably connected with the push rod 72, the push rod 72 is separated from the filter plate 51 by the roller 77, and the roller 77 is in rolling connection with the filter plate 51 during mutual movement, so that the abrasion of the roller 77 and the filter plate 51 can be reduced.

The limiting groove 78 and the limiting rod are matched to limit the dredging rod 71 to rotate, so that the position of the push rod 72 is kept stable, and the situation that the push plate 56 cannot push the push rod 72 due to the rotation of the dredging rod 71 is avoided.
In another embodiment, the push rod 72 comprises a first loop bar and a second loop bar, one end of the first loop bar is connected with one end of the second loop bar in a threaded manner, and the second loop bar is connected with the dredging bar 71. When the push rod 72 is abraded to cause leakage at the position of the sealing gasket 75, the first sleeve rod is rotated to adjust the connection length of the first sleeve rod and the second sleeve rod, so that the sealing gasket 75 can be sealed tightly again, and the problem of leakage of the feed liquid caused by abrasion of the push rod 72 is solved.
The implementation principle of the high-efficient anti-blocking plate and frame filter press of the embodiment of the application is as follows: when the filter chamber discharges slag, the filter plate 51 and the filter frame 52 move apart in sequence, when the filter frame 52 moves away from the filter plate 51, the push rod 72 gradually disengages from the filter plate 51 and the push plate 56, the acting force of the filter plate 51 and the push plate 56 on the push rod 72 is gradually reduced, the pulling force of the push rod 72 on the dredging rod 71 is gradually reduced, and the dredging rod 71 gradually moves downwards under the acting force of the return spring 73. When the filter plate 51 and the push plate 56 are completely separated from the push rod 72, the acting force of the filter plate 51 and the push plate 56 on the push rod 72 disappears, the pulling force of the push rod 72 on the dredging rod 71 disappears, the dredging rod 71 penetrates through the feed hole 55, and the particles blocked in the feed hole 55 are ejected out of the feed hole 55, so that the feed hole 55 is dredged, and the blockage of the feed hole 55 is reduced.
