The spiral scraper 23 fits the inner wall of the filter screen 14, and an arc-shaped groove is opened at the bottom end of the mounting groove. The spiral scraper 23 also fits the inner wall of the arc-shaped groove. A particle discharge channel running through the bottom of the ventilation duct 1 is opened on the right side; the output end of the motor 2 will drive the rotating rod 21 to rotate, and the rotating rod 21 will drive the fan 22 and the spiral scraper 23 to rotate at the same time. The rotation of the fan 22 will push the external air of the ventilation duct 1 into the ventilation duct 1, and filter the air entering the ventilation duct 1 through the filter 14.

[0033] Working principle: The operator first manually moves the block 19 to slide it away from the cover plate 11. The block 19 drives the T-shaped slider 17 to slide to one side of the inside of the T-shaped slide groove 16. At this time, the spring 18 is elastically compressed. When the block 19 is completely separated from the inside of the fixing block 12, the cover plate 11 is rotated to make one end of it away from the inside of the ventilator 1. Then, the filter 14 is placed inside the ventilator 1, so that the limit plates 15 on both sides of the filter 14 enter the corresponding limit grooves respectively, completing the preliminary fixation of the filter 14. Then, the cover plate 11 is rotated in the opposite direction to reset its position. The cover plate 11 is in the After the reset, a pair of pressure plates 13 fit with the corresponding limit plates 15, thereby fixing the pair of limit plates 15, and then release the clamping block 19, the spring 18 starts to elastically recover, the spring 18 drives the T-shaped slider 17 to slide inside the T-shaped slide groove 16, and the T-shaped slider 17 drives one end of the clamping block 19 to re-enter the fixed block 12. When the spring 18 drives the T-shaped slider 17 to reset, the position of the clamping block 19 is also reset again, and the clamping block 19 enters the fixed block 12 to complete the fixation of the cover plate 11, thereby completing the installation and fixation of the filter screen 14;

The output end of the motor 2 drives the rotating rod 21 to rotate, and the rotating rod 21 also drives the fan 22 to rotate. The rotation of the fan 22 will draw external air into the ventilation tube 1, and the filter tube 31 will block larger debris. The filter screen 14 will enter the ventilation tube 1 for filtration, and the filtered air will be transported to the outside of the construction area through the ventilation pipe 33, thereby realizing the exchange of the construction area with the external air. The rotation of the rotating rod 21 also drives the spiral scraper 23 to rotate. The rotation of the spiral scraper 23 will scrape off the filtered particles on the surface of the filter screen 14 and drive it to move toward the rectangular hole opened in the cover plate 11. In the process of continuous movement, the suction force on the particles will be weakened and they will fall under the action of gravity. Finally, they will pass through the rectangular hole and fall into the collection box 3 under the push of the spiral scraper 23, thereby completing the collection of the particles.
