The filter frame 7 and the filter screen 9 are connected by bolts. At the same time, in order to fill the gap between the filter frame 7 and the filter screen 9, a pad 91 is provided on the filter screen 9.

[0028] As an implementation method in this embodiment, in order to enable the filter frame 7 to be quickly disassembled, assembled and replaced, a mounting seat 3 for fixing the filter frame 7 is provided on the connecting beam 4, and a connecting head 8 adapted to the mounting seat 3 is provided on the filter frame 7. The connecting head 8 and the mounting seat 3 are clamped together by a limiting component, and in order to fill the gap between the filter frame 7 and the connecting beam 4, a pad 6 is provided on the connecting beam 4.

[0029] As an implementation method in this embodiment, in order to make the disassembly and assembly of the filter frame 7 more convenient and quick, the limiting assembly also includes a card joint 81 and a fixed plate 13. The top surface of the card joint 81 is provided with a mounting groove, and the fixed plate 13 is installed at the inner bottom of the mounting groove of the card joint 81 through a card spring 12. The card joint 81 is also provided with a sliding groove 82 for the fixing plate 13 to slide up and down. A card block 14 is hinged in the sliding groove 82 above the fixing plate 13, and a torsion spring is also provided between the card block 14 and the sliding groove 82. In the natural state, the end of the card block 14 protrudes from the sliding groove 82. At the same time, the fixed plate 13 is used to limit the rotation angle of the card block 14.

[0032] The working principle of the present invention is as follows: when the filter screen 9 of the spiral extrusion separator 1 needs to be replaced, the spiral extrusion separator 1 is first stopped, and then the straight rod is inserted into the mounting groove of the card joint 81 in the connecting head 8. When the straight rod moves downward, it contacts the fixing plate 13 and the blocking block 14 in turn, so that the blocking block 14 rotates into the sliding groove 82, and the blocking spring 12 is compressed. Through the above operation, the mounting seat 3 and the connecting head 8 are disengaged, and then the filter frame 7 is turned outward with the blocking block 5 as the axis to separate the filter frame 7 from the connecting beam 4, and then the blocking block 71 is separated from the blocking block 5, and the filter frame 7 can be removed. Then, the filter frame 7 is separated from the filter screen 9 by rotating the bolts on the filter frame 7. After the filter screen 9 of the filter frame 7 is replaced, the blocking block 71 of the filter frame 7 is aligned with the blocking block 5 to complete the docking. Then the straight rod in the connecting head 8 is taken out, and the limit of the fixing plate 13 and the blocking block 14 is released. The locking block 14 is hinged in the sliding groove 82 on the clamping joint 81 and is turned outward to the locking groove 31 under the action of the torsion spring. The fixed plate 13 arranged below the clamping block 14 is lifted upward under the action of the clamping spring 12, accelerating the speed of the clamping block 14 turning out, realizing the clamping connection between the connector 8 and the mounting seat 3. The clamping joint 81 is moved upward under the action of the preload spring 11 and the bottom plate 10, so that the connector 8 and the mounting seat 3 are fixed more firmly.
