A drain outlet is located at the bottom of the dust collection box near the air inlet. An upwardly inclined guide seat is located at the bottom of the dust collection box near the drain outlet. A trapping screen is installed at the higher end of the guide seat inside the dust collection box. A rotating shaft is installed at the center of the trapping screen and connected to the motor. A scraper is installed at the end of the rotating shaft facing the air inlet, and the scraper is attached to the end face of the trapping screen. A water inlet pipe is located at the top of the dust collection box, extending into the dust collection box and connected to an atomizing nozzle. The atomizing nozzle is located above the scraper and faces the trapping screen.

[0006] The top of the dust collector is equipped with several baffles above the flow guide seat, and the length of the baffles increases sequentially along the direction from the air inlet toward the interception screen.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0015] like Figure 1 As shown, a noise reduction and dust removal device for indoor building construction includes a dust collection box 1, an air inlet 2, a noise reduction plate 3, a noise reduction chamber 4, an exhaust fan 5, a motor 6, a drain outlet 7, a flow guide seat 8, a trap net 9, a rotating shaft 10, a scraper 11, a water inlet pipe 12, an atomizing nozzle 13, a baffle 14, a connecting ear plate 15, a connecting hole 16, a wheel seat 17, a movable wheel 18, a handle 19, and a support plate 20.

[0016] The dust collector 1 has an air inlet 2 at one end. The inner end of the dust collector 1 is enclosed by a noise reduction plate 3 to form a noise reduction chamber 4. An induced draft fan 5 and a motor 6 are installed in the noise reduction chamber 4. The bottom of the dust collector 1 is provided with a drain outlet 7 near the air inlet 2. The bottom of the dust collector 1 is provided with an inclined upward guide seat 8 at the drain outlet 7. A trap 9 is installed at the higher end of the guide seat 8 inside the dust collector 1. A rotating shaft 10 is installed in the center of the trap 9. The rotating shaft 10 is connected to the motor 6. A scraper 11 is installed at the end of the rotating shaft 10 facing the air inlet 2. The scraper 11 is attached to the end face of the trap 9. A water inlet pipe 12 is provided at the top of the dust collector 1. The water inlet pipe 12 extends into the dust collector 1 and is connected to an atomizing nozzle 13. The atomizing nozzle 13 is located above the scraper 11 and faces the trap 9.

[0017] The top of the dust collector 1 is provided with several baffles 14 above the guide seat 8. The length of the baffles 14 increases sequentially along the direction from the air inlet 2 to the interception screen 9.

[0018] When using this utility model, the device is placed at the downwind end of the indoor construction site. The exhaust fan 5 is turned on, and the dust-laden exhaust gas enters the dust collection box 1 through the air inlet 2. After being continuously impacted by several baffles 14, some dust settles onto the guide seat 8, and the remaining dust is intercepted and removed by the interception net 9. At the same time, the water entering through the water inlet pipe 12 forms a water mist through the atomizing nozzle 13 to blow away the dust. Meanwhile, the motor 6 drives the scraper 11 to scrape the interception net 9 to prevent blockage. The dirt is discharged from the drain outlet 7. During the process, the noise reduction plate 3 can reduce the noise generated by the exhaust fan 5 and the motor 6.

[0019] The dust collector 1 has several connecting ear plates 15 on the front and rear sides of the top. The connecting ear plates 15 have connecting holes 16. The dust collector 1 can be fixed to the relevant device through the connecting ear plates 15, making it more stable.

[0020] The bottom of the dust collector 1 is provided with several wheel seats 17, and movable wheels 18 are installed on the wheel seats 17. A handle 19 is provided on the outside of the closed end face of the dust collector 1, and the movable wheels 18 are provided to facilitate gripping the handle 19 to push the dust collector 1 to move.

[0021] The dust collection box 1 is equipped with a support plate 20, and the rotating shaft 10 passes through the support plate 20 to maintain a more stable rotation of the rotating shaft 10.

[0022] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
