[0027] As a further implementation of this solution, the cover shell 5 is annular, and side guard plates 6 are welded and fixed to the outer sides of both ends of the cover shell 5. The middle position of the side guard plate 6 is hollowed out, and the steel pipe 7 is arranged at the hollow position in the middle of the side guard plate 6. Through the above arrangement, the smoke generated during the cutting process of the steel pipe 7 can be effectively treated;

[0028] As a further implementation of the present invention, the second fixing plate 81 is fixedly connected to the housing 5 by bolts, the straight pipe 82 is connected to the inside of the housing 5 through the second fixing plate 81, and the angle between the straight pipe 82 and the second fixing plate 81 is 90°. Through the above arrangement, the stability of the connection between the dust removal mechanism 8 and the housing 5 can be ensured;

[0029] As a further implementation of this solution, the straight pipe 82 is connected to the inside of the vertical pipe 83, and the center points of the straight pipe 82 and the dust inlet 862 opened inside the filter column housing 861 are arranged on the same horizontal plane, and the angle formed between the straight pipe 82 and the vertical pipe 83 is 90°, which further improves the overall stability of the internal structure of the dust removal mechanism 8;

[0030] As a further implementation of this solution, the fan 84, the vertical pipe 83 and the bottom cover 85 are on the same axis, and the outer wall of the filter column housing 861 is in close contact with the inner wall of the vertical pipe 83, which effectively improves the stability of the entire device during operation;

Then, the laser cutting head 3 can complete the cutting during the rotation of the steel pipe 7. When the laser cutting head 3 is running, the fan 84 works at the same time. At this time, the fan 84 forms a negative pressure inside the upper end of the filter column shell 861. At this time, the elastic plastic plate 864 will keep moving upward (that is, it will not bend), thereby sealing the filter column shell 861. In this process, since the upper end of the filter column shell 861 is In the negative pressure state, the air inside the cover shell 5 enters the filter body 861 through the straight pipe 82, and then is discharged through the fan 84, so that the smoke and dust generated during the cutting process can be filtered together with the air inside the filter cover shell 861 to complete the collection of smoke and dust. After the cutting is completed, the laser cutting head 3 and the fan 84 stop working at the same time, and the elastic plastic plate 864 is bent, so that a certain gap is generated between the elastic plastic plate 864 and the filter column shell 861, and then the dust collected by the filter column shell 861 falls to the bottom of the filter column shell 861 for storage. The bottom cover 85 can be removed later, and the filter column shell 861 can be replaced, which is more convenient.
