Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 7 The utility model provides a technical solution: a high-pressure micro-mist dust suppression spray device, comprising an inner bracket 1, a support plate 2 and a jet pipe 4, the outer wall of the inner bracket 1 is welded with a support plate 2, and one side of the outer wall of the support plate 2 is welded with an outer bracket 3, the outer bracket 3 and the bottom end of the inner bracket 1 are connected to the jet pipe 4, and the outer wall of the jet pipe 4 is connected to a pipe joint 5, and the bottom end of the pipe joint 5 is butt-jointed with an atomizing nozzle 6, an auxiliary mechanism 7 is provided on the outer wall of the pipe joint 5, and the auxiliary mechanism 7 includes a sealing ring 701 connected to the atomizing nozzle 6, the top end of the atomizing nozzle 6 is connected to an expansion ring 702 through a clamping groove, a positioning seat 703 is welded to the top end of the outer wall of the atomizing nozzle 6, and the top end of the positioning seat 703 is connected to an extension plate 704 through a limiting hole; one side of the outer wall of the extension plate 704 is welded to the pipe joint 5, and the bottom end of the pipe joint 5 A fixing plate 705 is welded; a threaded rod 706 is connected to the internal thread of the fixing plate 705, and the positioning seat 703 is distributed at equal angles on the atomizing nozzle 6; the bottom end of the threaded rod 706 is connected to the lifting plate 707 through a bearing seat, and a limiting strip 708 is welded on one side of the bottom end of the fixing plate 705; the top end of the outer wall of the lifting plate 707 is connected to the fixing strip 709, and a guide hole corresponding to the limiting strip 708 is provided on the side of the lifting plate 707 away from the fixing strip 709; the inner bracket 1 and the outer bracket 3 are in a "U" shape, and a sealing groove corresponding to the sealing ring 701 is provided in the middle of the bottom end of the pipe joint 5; a fixing groove corresponding to the fixing strip 709 is provided on the outer wall of the atomizing nozzle 6, and the lifting plate 707 and the fixing strip 709 form an integrated structure, the fixing plates 705 are distributed at equal angles on the pipe joint 5, and the expansion ring 702 is made of water-absorbing material.

[0022] During specific implementation, during the use of the high-pressure fine mist dust suppression spray device, the water flow is guided to the atomizing nozzle 6 through the jet pipe 4, and then the water is atomized by the atomizing nozzle 6 to form micron-sized water droplets. These tiny water droplets can effectively absorb the dust particles in the air, make them increase their weight and settle quickly, thereby achieving the effect of dust suppression and optimizing the on-site working environment. Afterwards, the atomizing nozzle 6 is arranged in a "U" shape through the mutual cooperation of the inner bracket 1, the support plate 2 and the outer bracket 3. Because the atomizing nozzle 6 is distributed in a "U" shape, it can increase the contact area between the liquid and the air, which helps to better atomize the liquid and form fine droplets, thereby making the fine droplets more evenly distributed in the target area, and the U-shaped design helps to control the flight trajectory of the droplets, reduce the drift of the droplets in the air, and then improve the uniformity of the spray;

[0023] As the use time increases, when the atomizing nozzle 6 needs to be disassembled for cleaning or replacement, the threaded rod 706 in the fixing plate 705 is first rotated downward. Since the bottom end of the threaded rod 706 is connected to the lifting plate 707 through the bearing seat, the threaded rod 706 moves downward to drive the lifting plate 707 to move downward together. Moreover, since the lifting plate 707 is connected to the fixing bar 709, the movement of the lifting plate 707 drives the fixing bar 709 to move together. Moreover, since the lifting plate 707 is slidably connected to the limiting bar 708, the movement of the lifting plate 707 is guided by the limiting bar 708, and then The lifting plate 707 is moved stably until the fixing strip 709 is disconnected from the atomizing nozzle 6 and moves down to the designated position. At this time, the atomizing nozzle 6 is moved down again until the positioning seat 703 is disconnected from the extension plate 704, and the atomizing nozzle 6 is removed from the bottom end of the pipe joint 5. Thereafter, the atomizing nozzle 6 is cleaned or replaced, and the replacement of the atomizing nozzle 6 can be completed without using a special disassembly tool to repeatedly turn multiple sets of screws, thereby saving time and energy, thereby facilitating the replacement of the nozzle and ensuring uniformity when the high-pressure micro-mist dust suppression spray device is used.

[0024] When it is necessary to dock the atomizing nozzle 6 with the pipe joint 5 to complete the installation, since the atomizing nozzle 6 is connected to the positioning seat 703, the movement of the atomizing nozzle 6 drives the positioning seat 703 to move together. First, the positioning seat 703 is inserted into the extension plate 704 to limit the atomizing nozzle 6 to prevent the atomizing nozzle 6 from moving at will and affecting the installation. Then, the threaded rod 706 is rotated upward so that the threaded rod 706 drives the lifting plate 707 to move upward until the fixing bar 709 docks with the atomizing nozzle 6. At this time, the atomizing nozzle 6 and the fixing bar 709 are engaged, and then the atomizing nozzle 6 is fixed so that the atomizing nozzle 6 is installed at the bottom of the pipe joint 5.

[0025] At this time, at the connection between the pipe joint 5 and the atomizing nozzle 6, the two squeeze the sealing ring 701 and the expansion ring 702, thereby causing the sealing ring 701 and the expansion ring 702 to deform, and then seal the connection between the pipe joint 5 and the atomizing nozzle 6. Because the expansion ring 702 is made of water-absorbing material, when water flows through the sealing ring 701 and reaches the expansion ring 702, the expansion ring 702 absorbs water and expands to seal again, thereby ensuring the sealing of the connection between the pipe joint 5 and the atomizing nozzle 6.

[0026] To sum up, when this high-pressure micro-mist dust suppression spray device is used, the water is first pressurized to 20-40MPa through a high-pressure pump, and then the water flow is directed to the atomizing nozzle 6 through the jet pipe 4, and then the water is atomized by the atomizing nozzle 6 to form micron-sized water droplets. These tiny water droplets can effectively adsorb dust particles in the air, increase their weight and settle quickly, thereby achieving the effect of dust suppression. By making the atomizing nozzle 6 distributed in a "U" shape, the fine droplets can be more evenly distributed in the target area, and the U-shaped design helps to control the flight trajectory of the droplets, reduce the drift of the droplets in the air, and thus improve the uniformity of the spray. The auxiliary mechanism 7 makes it convenient for the staff to remove the atomizing nozzle 6, and then clean or replace the atomizing nozzle 6, thereby saving time and energy. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
