[0029] like Figure 1-Figure 4 As shown, a squeezing cage filtering device of the utility model comprises a cage body and a filter screen 6 arranged in the cage body, the cage body comprises a frame 1 and a plurality of ribs 2, a plurality of notches 11 are provided on the inner side of the circumference of the frame 1, a plurality of ribs 2 are slidably inserted in the corresponding notches 11, and a pressure ring 3 is fixedly installed at both ends of the frame 1 by fixing bolts, and the two ends of the filter screen 6 are respectively abutted against two pressure rings 3, and the pressure ring 3 is used to block the notches 11. When replacing the rib 2, it is only necessary to remove the pressure ring 3 from the frame 1 and pull out the rib 2 for replacement, which is simple, convenient and quick.

[0030] In this embodiment, an annular groove 31 is provided on the inner side of the circumference of the pressure ring 3, and the notch 11 passes through the pressure ring 3 and is connected with the annular groove 31. A sealing ring 4 is rotatably installed in the annular groove 31, and the sealing ring 4 is used to seal the notch 11. A through groove 41 passing through the sealing ring 4 is provided on the sealing ring 4. The sealing ring 4 is rotated to connect the through groove 41 with the notch 11, so that the rib 2 can be pulled out without removing the pressure ring 3, thereby further improving the convenience of replacing the rib 2.

[0031] In this embodiment, a blocking block 5 is provided in the through slot 41, and the blocking block 5 is used to block the through slot 41 to prevent the rib 2 from slipping out of the through slot 41. A mounting head 51 is provided on one side of the blocking block 5, and a mounting groove 411 is provided at one end of the through slot 41. The mounting head 51 is fixedly installed in the mounting groove 411 to prevent the blocking block 5 from falling off.
