[0018] like Figures 1-4 As shown, a dust control device for building demolition includes a housing 1 with an air inlet 2 at its upper end and an air outlet 3 on its side wall. It also includes partitions 4, an intake fan 5, a mixing assembly 6, and an atomizing assembly 7. The partitions 4 are fixedly connected between opposite inner walls of the housing 1, symmetrically distributed, and form a dust collection chamber 8 between them. An atomizing chamber 9 is formed between the partitions 4 and the side wall of the housing 1 near the air outlet 3. The intake fan 5 is fixedly connected to the opposite inner side wall of the housing 1 near the air inlet 2. The mixing assembly 6 is rotated and located at the bottom of the dust collection chamber 8. The atomizing component 7 is fixedly connected to the intake fan 5 and located at the bottom of the atomizing chamber 9. A water inlet pipe 15 is connected to the bottom of the housing 1 and is connected to the bottom of the dust collection chamber 8. A solenoid valve 16 is installed in the middle section of the water inlet pipe 15. A fixed amount of water is introduced into the bottom of the housing 1 through the water inlet pipe 15. The solenoid valve 16 controls the opening and closing of the water inlet pipe 15. Dust-laden air is pushed by the intake fan 5 into the integrated chamber and comes into contact with the water surface at the bottom for dust suppression. When the intake fan 5 rotates, it drives the mixing component 6 to rotate synchronously, mixing the water and dust particles, ensuring that the dust continuously entering the dust collection chamber 8 comes into contact with the water surface.

[0019] The upper end of the partition 4 is bent towards the air outlet 3. A strip hole 10 is opened in the middle of the partition 4. The strip holes 10 are arranged at uniform intervals. A mesh 11 is fixedly connected between the bottom wall of the partition 4 and the inner bottom wall of the housing 1. The dust collection chamber 8 is connected to the atomizing chamber 9 through the mesh 11. After contacting the liquid surface, the air flows to both sides and enters the atomizing chamber 9 through the mesh 11 and the strip hole 10. In the atomizing chamber 9, the water mist generated by the atomizing component 7 comes into contact with the air again to achieve air dust reduction. Finally, the air is discharged through the air outlets 3 on both sides of the housing 1, carrying some water mist with it, which increases the dust prevention effect of the device.

[0020] like Figure 3 and Figure 4As shown, in order to realize the water stirring inside the shell 1, promote the mixing of dust particles and water, keep the water surface to absorb the ability of dust particles, push the mixing assembly 6 includes the rotating rod 12 and the spiral blade 13, one end of the rotating rod 12 is fixedly connected to the bottom end of the inlet fan 5, the other end of the rotating rod 12 is rotatably arranged on the bottom wall of the shell 1, the spiral blade 13 is fixedly arranged on the bottom of the outer side wall of the rotating rod 12, the rotating rod 12 is rotated synchronously by the fan blade of the inlet fan 5 to drive the spiral blade 13 to rotate, and the water in the shell 1 is pushed to flow. In order to avoid the water containing dust particles into the atomizing chamber 9, the water is filtered by the screen 11, so that the atomizing assembly 7 is normally atomized.

[0021] As Figure 3 and Figure 4 The atomizing assembly 7 includes an atomizing sheet 14, which is arranged on the inner bottom wall of the atomizing chamber 9. The atomizing sheet 14 is arranged at equal intervals. The water is atomized by the plurality of atomizing sheets 14 on the inner bottom of the atomizing chamber 9, and the atomizing chamber 9 is filled, and the flowing air is dusted again.

[0022] Among them, the side wall of the shell 1 adjacent to the air outlet 3 is fixedly connected with a positioning plate 17, the positioning plate 17 is arranged in an inverted L shape, the positioning plate 17 is provided with positioning holes 18 parallel to the side wall of the shell 1, the positioning holes 18 are arranged at equal intervals, the shell 1 is hung by the positioning plate 17, or the shell 1 is fixed by the positioning holes 18, so that the device is hung and limited.

[0023] In specific use, the operator hangs the shell 1 by the positioning plate 17, or fixes it by the positioning hole 18, connects the water inlet pipe 15 with the external water pipeline, opens the electromagnetic valve 16, and then the water enters the bottom of the shell 1. Close the electromagnetic valve 16 to store a certain amount of water in the bottom of the shell 1. In order to keep the atomized water clean, the water page should not exceed the screen 11.

[0024] In use, the inlet fan 5 is powered on to suck the external gas into the dust collecting chamber 8. The flowing air contacts the liquid surface to dust, and drives the mixing assembly 6 connected with the fan blade of the inlet fan 5 to rotate. The rotating rod 12 rotates synchronously by the fan blade of the inlet fan 5 to drive the spiral blade 13 to rotate, and the water in the shell 1 is pushed to flow. In order to avoid the water containing dust particles into the atomizing chamber 9, the water is filtered by the screen 11, so that the atomizing assembly 7 is normally atomized.

[0025] The air enters the atomizing chamber 9 through the screen 11 and the strip-shaped hole 10 on both sides. In the atomizing chamber 9, the water is atomized by the plurality of atomizing sheets 14 on the inner bottom of the atomizing chamber 9, and the atomizing chamber 9 is filled, and the flowing air is dusted again. Finally, the air is discharged through the air outlet 3 on both sides of the shell 1, and part of the water mist is taken away, which increases the dustproof effect outside the device.
