Column 9, the top of the threaded ring 10 is provided with a bearing 11, and the bearing 11 is provided with a fastening plate 12, and a second inclined groove 13 is provided on one side of the top of the fastening plate 12, and the second inclined groove 13 is against the first inclined groove 8, and a guide plate 14 is provided on one side of the dust removal tower 1, and a guide groove is provided on the guide plate 14, and the fastening plate 12 is against the guide groove. In this embodiment, the exhaust channel of the cement grinding device is connected through the air inlet pipe 3, and then the filter layer 7 of the sealing plate 6 is against the filter tank, and the sealing plate 6 is against the sealing groove, and then the personnel hold and rotate the threaded ring 10, and the threaded ring 10 rotates upward on the threaded column 9, through the bearing 11 and the fastening plate The plate 12 is against the guide groove of the guide plate 14, which enables the fastening plate 12 to move linearly with the threaded ring 10, but does not follow the rotation angle of the threaded ring 10. The fastening plate 12 moves linearly upward, and the second inclined groove 13 of the fastening plate 12 contacts and presses against the first inclined groove 8. Through the inclination angle of the first inclined groove 8 and the second inclined groove 13, the fastening plate 12 can exert a lateral force on the sealing plate 6, so that the sealing plate 6 is firmly and reliably assembled in the sealing groove. The dust generated by the cement grinding device enters the dust removal tower 1 through the discharge channel and the air inlet pipe 3, and is filtered in the air by the filter layer 7. The dust is then sprayed by the spray mechanism so that the dust passing through the filter layer The air after 7 is sprayed here to make the fine particles come into contact with water, and finally discharged through the exhaust mechanism, achieving efficient dust removal and filtration, and discharging air that meets the standards. The sprayed water directly washes away the dust in the filter layer 7, and then is discharged through the sewage discharge mechanism. After long-term use, in order to ensure that the air after dust removal and filtration meets the emission standards, it is necessary to regularly inspect and replace the filter layer 7. At this time, by rotating the threaded ring 10 in the opposite direction, the threaded ring 10 is rotated downward on the threaded column 9, and the second inclined groove 13 of the fastening plate 12 leaves the first inclined groove 8, so that the filter layer 7 can be replaced by taking out the sealing plate 6, and the filter layer 7 can be quickly replaced and inspected to ensure the dust removal and filtration efficiency.

[0024] In this solution, the spray mechanism includes an annular pipe 15 and a water supply pipe 16.
