Description

Technical Field

[0001] The present invention relates to the technical field of atomized dust suppression, and specifically to an atomized dust suppression device for environmental protection construction in construction. Background Art

[0002] Generally, a fog cannon atomizes water into micron-sized particles and then sprays them into the air through a fan to adsorb dust, causing it to coalesce and settle. For example, at a building demolition site or other environmental protection construction scenarios, a fog cannon can quickly suppress dust. In existing fog cannons, water is generally atomized by an atomizing nozzle and then sprayed into the jet airflow of the fan, so that the jet airflow carries the water mist and sprays it far away. The atomizing nozzles are generally arranged in a circle. Among them, the water mist broken by the atomizing nozzles in the lower part needs to overcome gravity to enter the jet airflow. Some atomizing nozzles at the fog cannon mouth of the existing fog cannons are set at different inclination angles to improve the average degree of the travel distance of the water mist at each position in the jet airflow. However, the angle of the atomizing nozzle relative to the fog cannon mouth is fixed. When the elevation angle of the fog cannon is adjusted, the angle of the atomizing nozzle is not easily adjusted accordingly. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. Through the setting of the atomization module and the pitching ring, when the electric telescopic rod expands and contracts, it drives the pitching ring to deflect, thereby controlling the pitching angle of the pitching ring relative to the ring pipe. When the top end of the pitching ring deviates from the ring pipe, the pitching ring drives the nozzle on the upper half of the ring pipe through the connecting rod. The nozzle drives the docking pipe to rotate, causing the nozzle to deflect upward, reducing the angle between the mist ejected by the nozzle on the upper half and the jet airflow of the air duct. At the same time, the angles of the multiple nozzles on the lower half are pushed to deflect upward, increasing the angle between the mist ejected by the nozzles on the lower half and the jet airflow of the air duct, improving the residence time of the mist ejected by the nozzles on the lower half in the jet airflow, realizing the control of the pitching angle of the nozzle according to the pitching angle of the air duct, making the atomized airflow more concentrated, reducing the ineffective diffusion of the water mist, realizing the control of the diffusion distance of the mist ejected by the air duct, and cooperating with the control of the pitching angle of the air duct to adjust the working area position of the air duct, facilitating dust suppression according to the position of the dust source.

[0023] 2. Through the setting of the transverse module, the driving motor 1 drives the gear 1 to rotate through the prism rod, the gear 1 drives the prism rod to rotate, the prism rod drives the gear 2 to rotate through the arc tooth rod, the gear 2 drives the screw rod 2 to rotate, and the screw rod 2 drives the middle transfer ring to move horizontally through the threaded hole. The middle transfer ring drives the pitching ring to move horizontally. The ends of the multiple connecting rods close to the pitching ring are in a converging state towards the middle as a whole. When there is a crosswind, for example, a crosswind from right to left, the water mist on the left side of the jet airflow is likely to break away. The driving motor 1 drives the prism rod to rotate, the prism rod drives the prism rod to rotate through the gear 1, the prism rod drives the gear 2 to rotate through the arc tooth rod, the gear 2 drives the screw rod 2 to rotate, and the screw rod 2 drives the middle transfer ring to move horizontally to the left through the threaded connection with the middle transfer ring. The middle transfer ring drives the left nozzle to deflect to the right through the left connecting rod, and the middle transfer ring pulls the right nozzle to deflect to the right through the right connecting rod, realizing the overall deflection of multiple nozzles to the right, thereby increasing the residence time of the atomized airflow in the jet airflow and improving the adaptability to crosswinds.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 to 7, in an embodiment of the present invention, an environmental protection construction atomizing dust reduction device includes an electrical cabinet 100 and a wind tube 200.

The annular tube 320 is fixedly installed at one end of the wind tube 200, and a plurality of atomizing modules 310 are rotatably installed on the annular tube 320, and the angles of the atomizing modules 310 are adjustable. The pitching ring 330 is installed at one end of the wind tube 200 and is connected between the pitching ring 330 and the plurality of atomizing modules 310. The pitching ring 330 is used to drive the atomizing modules 310 to deflect. The base ring 390 is fixedly installed on the wind tube 200, and a driving ring 360 is slidably installed on the base ring 390. The rotating ring 340 is movably installed on the driving ring 360 and is rotatably connected between the rotating ring 340 and the pitching ring 330.

The transverse module 370 is installed between the driving ring 360 and the base ring 390, and the transverse module 370 is used to drive the rotating ring 340 to move horizontally. The propulsion module 380 is installed on the base ring 390, and the base ring 390 is used to drive the driving ring 360 and the pitching ring 330 to move back and forth. The atomizing module 310 includes a docking pipe 311, the docking pipe 311 is rotatably connected to the annular tube 320, one side of the docking pipe 311 is fixedly communicated with a nozzle 312, a rocker arm 313 is installed on the docking pipe 311, and a plurality of ball seats 331 are fixedly installed on one side of the pitching ring 330.

[0036] Specifically, when the electric telescopic rod 350 expands and contracts, it drives the pitching ring 330 to deflect, thereby controlling the pitching angle of the pitching ring 330 relative to the ring pipe 320. When the top end of the pitching ring 330 deviates from the ring pipe 320, the pitching ring 330 pulls the nozzle 312 on the upper half of the ring pipe 320 through the connecting rod 332. The nozzle 312 drives the docking pipe 311 to rotate, causing the nozzle 312 to deflect upward, reducing the angle between the mist ejected from the nozzles 312 in the upper half and the jet airflow of the air duct 200.

In cooperation with the control of the pitching angle of the air duct 200, the working area position of the air duct 200 is adjusted, facilitating dust suppression according to the position of the dust source.
