[0034] Working principle: When installing the filter plate 8, it first needs to be inserted into the mounting frame 2. Due to their mutual matching, the installation position of the filter plate 8 can be positioned, and the filter plate 8 abuts against the positioning frame 7. At this time, the positioning rod 13 will pass through the inside of the first positioning hole 10. Then, the fixing frame 3 and the connecting frame 5 are inserted into the inside of the mounting frame 2. Due to the mutual matching of the inside of the fixing frame 3 and the mounting frame 2, the installation position of the fixing frame 3 and the multiple grid bars 4 can be positioned until the rectangular sealing ring 6 contacts the outer wall of the filter plate 8. The positioning rod 13 will enter the second positioning hole 12, and then the internal thread block 15 will be screwed onto the outer wall of the screw 14. When the internal thread block 15 is tightened with a hex wrench, pressure will be applied to the grooved block 11 in the direction of the filter plate 8. At the same time, pressure will be applied to the fixing frame 3, the connecting frame 5 and the rectangular sealing ring 6 in the direction of the filter plate 8 until the rectangular sealing ring 6 and the filter plate 8 are tightly abutted. After that, the filter plate 8 is installed. And through the setting of the rectangular sealing ring 6, dust in the air can be prevented from entering the bumper 1 from the gap between the filter plate 8 and the positioning frame 7.

[0035] When the filter plate 8 needs to be removed, the internal threaded block 15 needs to be removed so that the fixing frame 3 can be removed, and then the filter plate 8 can be taken out from the inside of the mounting frame 2. The operation is simple and quick, which further improves the convenience of disassembling and assembling the filter plate 8, so as to facilitate cleaning and maintenance.
