[0027] Please refer to the following instructions for the atomizing spray mechanism.

[0028] The atomizing spray mechanism includes a column 4, which is detachably connected to the connecting plate 2. A movable arm 6 is provided in the upper half of the column 4 away from the connecting plate 2. The lower end of the movable arm 6 is hinged to the column 4 through a hinge seat 9. The column 4 is provided with an adjustment mechanism for adjusting the angle between the column 4 and the movable arm 6.

[0029] An atomizing nozzle 7 and a guide pipe 8 are provided on the movable arm 6. The atomizing nozzle 7 is fixedly connected to the upper end of the movable arm 6. The guide pipe 8 is connected to the atomizing nozzle 7. An air blowing assembly is provided on the upper end of the movable arm 6. The air blowing assembly is placed between the atomizing nozzle 7 and the column 4.

[0030] Next, the use of the dust treatment device and the advantages of the technical solution are explained.

[0031] The guide pipe 8 is connected to the pipeline system buried deep on the ground or underground, which is beneficial to the groundwater or water in the fire water pool to provide a water source for the atomizing nozzle 7. After the atomized droplets are sprayed out through the atomizing nozzle 7, they will cooperate with the enclosure 1 to increase the humidity of the air in the construction area and absorb dust particles and impurities in the air, thereby playing a role in dust reduction and dust removal.

[0032] The angle between the column 4 and the movable arm 6 is adjustable, and the spraying height of the atomizing nozzle 7 on the movable arm 6 can be adjusted according to the height of the enclosure 1, thereby reducing the impact of outdoor strong winds on the water mist and increasing the hovering time of the water mist in the construction area. At the same time, the atomized droplets sprayed from the atomizing nozzle 7 will also be blown by the blower assembly and blown toward the center of the construction area, further ensuring that the droplets will not overflow from the top of the enclosure 1 to the outside of the construction area, thereby improving the dust reduction effect.

[0033] In a better implementation.

[0034] The adjustment mechanism includes a positioning plate 15, on which are mounted two second positioning bolts 17, one of which passes through a fourth positioning hole 16 provided on the positioning plate 15 and is threadedly connected to a second positioning hole 13 provided on the outside of the movable arm 6, and the other second positioning bolt 17 passes through the fourth positioning hole 16 and is threadedly connected to a third positioning hole 14 provided on the outside of the column 4. The positioning plate 15 has a plurality of fourth positioning holes 16 on the outside, the column 4 has a plurality of third positioning holes 14 on the outside, and the movable arm 6 has a plurality of second positioning holes 13 on the outside, and the second positioning holes 13 are evenly arranged along the length direction of the movable arm 6.

[0035] comprehensive Figure 3 , Figure 4 and Figure 5 The specific working mode of the regulating mechanism is:

[0036] When adjusting the height of the movable arm 6, the second positioning bolt 17 is screwed out from the corresponding second positioning hole 13 to release the locking of the movable arm 6 by the second positioning bolt 17 on the positioning plate 15. After unlocking, the movable arm 6 is rotated and rotated around the hinge seat 9. When the upper end of the movable arm 6 approaches the upper end of the column 4, the atomizing nozzle 7 is lifted upward. On the contrary, when the upper end of the movable arm 6 is away from the upper end of the column 4, the atomizing nozzle 7 falls. When locking the adjusted movable arm 6 again, the second positioning bolt 17 is screwed into the corresponding second positioning hole 13.

[0037] For the specific structure of the air blowing assembly, please refer to the following description.

[0038] The air blowing assembly includes a cover plate 10 disposed at the upper end of the movable arm 6 . The cover plate 10 is detachably connected to a side of the movable arm 6 close to the column 4 . A blower fan 11 is disposed on the cover plate 10 . The cover plate 10 is arranged on one side of the atomizing nozzle 7 .

[0039] comprehensive Figure 3 and Figure 4 , the specific operation mode of the blast assembly is:

[0040] The motor in the cover plate 10 drives the fan blades to rotate. When the airflow passes through the atomizing nozzle 7, it will blow the droplets sprayed from the atomizing nozzle 7 toward the center of the construction area. In conjunction with the cover plate 10, the spraying range is increased while preventing the droplets from spilling outside the enclosure 1.

[0041] In a preferred embodiment, a plurality of first positioning bolts 5 are mounted on the column 4, and the first positioning bolts 5 pass through the column 4 and are threadedly connected to the first positioning holes 3 provided on the outside of the connecting plate 2. When the column 4 is removed from the connecting plate 2, the first positioning bolts 5 can be screwed out of the corresponding first positioning holes 3.

[0042] In another preferred embodiment, the cover plate 10 is equipped with a plurality of third positioning bolts 18, which pass through the cover plate 10 and are threadedly connected to the fifth positioning holes 19 provided on the outer side of the movable arm 6. When the cover plate 10 is removed from the movable arm 6, the third positioning bolts 18 can be screwed out of the corresponding fifth positioning holes 19.

[0043] Detachable connection mode makes replacement and maintenance of each component easy.

[0044] Based on the previous embodiment, further optimization can be made. Specifically, a groove seat 12 is provided on the side of the cover plate 10 close to the movable arm 6, and the groove seat 12 is clamped on the outer side of the movable arm 6. During assembly, the cover plate 10 can be pre-matched with the movable arm 6 through the groove seat 12, so as to facilitate the screwing in of the third positioning bolt 18 on the cover plate 10.

[0045] In another preferred embodiment, the adjustment mechanism includes an electric push rod 20, which is placed between the movable arm 6 and the column 4, the mounting end of the electric push rod 20 is rotatably connected to the column 4, and the output end of the electric push rod 20 is rotatably connected to the movable arm 6.

[0046] comprehensive Figure 6 The specific working mode of the regulating mechanism is:

[0047] The angle adjustment between the movable arm 6 and the column 4 is controlled by the electric push rod 20. When the electric push rod 20 pushes the movable arm 6, the atomizing nozzle 7 falls down. When the electric push rod 20 pulls the movable arm 6, the atomizing nozzle 7 rises upward. Of course, in addition to the electric push rod 20, other linear push mechanisms can also be used as substitutes, such as pneumatic push rods, hydraulic push rods, etc. Compared with manual adjustment, the control method using the electric push rod 20 saves manpower and is easy to operate, but correspondingly, the failure rate and maintenance cost are also increased.

[0048] The working principle of the present application: the guide pipe 8 is connected to the pipeline system deeply buried on the ground or underground, which is beneficial to the groundwater or water in the fire water pool to provide a water source for the atomizing nozzle 7. After the atomized droplets are sprayed out through the atomizing nozzle 7, they will cooperate with the enclosure 1 to increase the humidity in the air in the construction area and absorb dust particles and impurities in the air. The angle between the column 4 and the movable arm 6 is adjustable, and the spraying height of the atomizing nozzle 7 on the movable arm 6 can be adjusted according to the height of the enclosure 1. At the same time, the atomized droplets sprayed from the atomizing nozzle 7 will also be blown by the blowing assembly and blown toward the center of the construction area, further ensuring that the droplets will not overflow from the top of the enclosure 1 to the outside of the construction area.
