In addition, the directional terms mentioned in the following embodiments, such as "upper", "lower", "left", "right", etc., are only with reference to the directions in the drawings. Therefore, the directional terms used are for illustration rather than to limit the present invention.

[0019] The present invention will be further described below in conjunction with the drawings and preferred embodiments.

[0020] Embodiment: A dust removal device for civil engineering construction, see the appendix Figure 1 - Appendix Figure 11 It includes a box body 1, a dust suction pipe 2, an air inlet pipe 3, an air extraction fan, a spiral plate 4, a spray head 41 and a spray pipe 5. A plurality of rollers 13 for driving the box body 1 to move are arranged at the bottom of the box body 1, and a motor for driving the rollers 13 to rotate is arranged at the bottom of the box body 1; the dust suction pipe 2 is fixedly connected to the top of the box body 1, and the axis of the dust suction pipe 2 is vertically arranged; the air inlet pipe 3 is fixedly connected to one side of the top of the car wash pipe; the air extraction fan is arranged at a position near the top on one side of the box body 1, and the air extraction fan is used to exhaust the air in the box body 1 to the outside; the spiral plate 4 is arranged in the dust suction pipe 2 and spirally arranged around the axis of the dust suction pipe 2, the outer side of the spiral of the spiral plate 4 is attached to the inner wall of the dust suction pipe 2, and a spiral channel is arranged spirally inside the spiral plate 4; a number of spray heads 41 are arranged on the spiral plate 4, and the multiple spray heads 41 are arranged along the spiral direction of the spiral plate 4 on the spiral plate 4, and the spray heads 41 are arranged at the bottom of the part of the spiral plate 4 connected to the spray heads 41; the spray pipe 5 is arranged as an annular pipe, and the spray pipe 5 is arranged at a position in the dust suction pipe 2 adjacent to the bottom of the air inlet pipe 3.

[0021] Through the action of the rollers 13 at the bottom of the box body 1, the box body 1 moves in the construction site. During the movement of the box body 1, the air extraction fan works. Under the action of the air extraction fan, the outside air with dust enters the dust suction pipe 2 through the air inlet pipe 3, and spirally flows downward in the dust suction pipe 2 under the action of the spiral plate 4 in the dust suction pipe 2. During the spiral flow of the air, the dust particles will continuously change the flow direction and hit the inner wall of the dust suction pipe 2, so that the dust is easily deprived of power and falls onto the spiral plate 4. And during the spiral downward flow of the air, the water mist sprayed by the spray heads 41 will adsorb the dust in the air and drive the adsorbed dust to fall onto the spiral plate 4. The water sprayed by the spray pipe 5 can not only adsorb part of the dust, but also drive the dust on the spiral plate 4 to flow spirally downward along the spiral plate 4 into the box body 1. The dust remains in the box body 1 while the clean air is discharged through the air extraction fan.

[0022] Specifically, this embodiment further includes a rotating shaft 6. The rotating shaft 6 is rotatably connected to the top of the dust suction pipe 2 and is coaxially arranged with the dust suction pipe 2. The spiral plate 4 is fixedly connected to the rotating shaft 6; the inside of the rotating shaft 6 is hollow, and the hollow cavity inside the rotating shaft 6 is communicated with the spiral channel inside the spiral plate 4. The top of the rotating shaft 6 extends upward out of the dust suction pipe 2 and is connected to a water inlet pipe 61, and the rotating shaft 6 is rotatably connected to the water inlet pipe 61.

[0023] Specifically, a vertically oriented guide groove 21 is provided on the inner wall of the dust suction pipe 2.

The bottom of the soft brush 71 contacts the top of the part of the spiral plate 4 that contacts the soft brush 71.

[0024] When dust adheres to the spiral plate 4 and cannot be washed away by the flow of water, the rotating shaft 6 drives the spiral plate 4 to rotate. Under the action of the spiral plate 4, the lifting rod 7 will move up and down, and the soft brush 71 at the bottom of the lifting rod 7 will brush the dust adhering to the spiral plate 4, so that the dust adhering to the spiral plate 4 will fall off from the spiral plate 4.

[0030] Through the arrangement of the support frame 81 and the lifting frame 83, when the filter net 8 is fully adsorbed with dust at the top, the lifting frame 83 moves downward, causing the filter net 8 to disengage from the bottom of the dust suction pipe 2, and leaving a sufficient distance between the filter net 8 and the dust suction pipe 2 to enable the filter net 8 to flip 180°. Then the lifting frame 83 moves upward again, covering the filter net 8 at the bottom of the dust suction pipe 2. At this time, the side of the filter net 8 adsorbed with dust is located at the bottom of the filter net 8, and the water flowing downward in the dust suction pipe 2 will wash off the dust adsorbed on the bottom side of the filter net 8 during the process of passing through the filter net 8.
