A conical guide cover 11 for supporting air flow is arranged at the lower end of the flow opening 10. When the device is running, multiple negative pressure spaces are formed inside the dust removal pipe 1 by running the negative pressure vacuum pump 2, the guide pipe 4, the inclined guide plate 7 and the rotating flow-aiding tooth 8 at the same time, so that the outer The side air is continuously and efficiently sucked into the interior of the device for dust removal. Specifically, through the operation of the negative pressure vacuum pump 2, the air inside the dust removal pipe 1 is discharged to the outlet pipe 202 through the air inlet pipe 201 and the guide pipe 4, so that a negative pressure space is formed above the guide pipe 4, so that the air above can circulate thereto, and then, under the guiding limit of the two inclined guide plates 7 and the acceleration of the air flow by the rotating flow-aiding teeth 8, the volume of the air between the two inclined guide plates 7 is increased in a short time, thereby increasing the pressure between the two inclined guide plates 7, while the air pressure at the other end of the inclined guide plate 7 remains unchanged, so that the air flows quickly to the other side and is sucked by the negative pressure vacuum pump 2, and through the conical guidance of the conical guide cover 11, the air is guided and gathered at the same time when it flows into the dust removal pipe 1, thereby accelerating the flow of the airflow flowing into the device for multiple times, and then under the adsorption of the dust removal device inside the device, the impurities in the gas are suction-type dust removal.
