[0024] Embodiment 1

[0025] See Figures 1-6 , this embodiment provides an atomizing dust suppression device at a construction site, including a box body 1, a water tank assembly 5 is assembled on the side of the box body 1, a motor 21 is assembled on the top of the box body 1, and a box door 8 is fixedly connected to the front of the box body 1; At the top of the box body 1, a rotating pipe 22 is rotatably connected through a bearing. A negative pressure fan 23 is assembled on the outer wall of the rotating pipe 22. An extrusion block 24 is fixedly sleeved on the outer wall of the rotating pipe 22. A collecting groove 25 is hinged to the front surface of the inner wall of the box body 1. A hydraulic chamber 26 is fixedly connected to the side of the box body 1. A first hydraulic rod 27 is slidably connected to one end of the piston on the inner wall of the hydraulic chamber 26. A spring 28 is movably sleeved on the outer wall of the first hydraulic rod 27. A second hydraulic rod 29 is slidably connected to the piston at one end inside the hydraulic chamber 26. The second hydraulic rod 29 is hinged to the side of the collecting groove 25. A rotary joint 215 is assembled at the bottom of the rotating pipe 22. A diffusion port 214 is fixedly connected to the bottom of the rotary joint 215. An atomizing pipe 213 is fixedly penetrated through the diffusion port 214. A feeding device 3 for feeding a precipitant is assembled inside the box body 1. A cleaning device 4 for cleaning impurities is assembled inside the box body 1. Through key components such as the rotating pipe 22, the negative pressure fan 23, the atomizing pipe 213, the feeding device 3, and the cleaning device 4, dust can be effectively controlled at a construction site, the dust in the air can be reduced by atomization, and the cleanliness of the construction environment can be increased.

[0026] A filter screen 210 is fixedly connected to the bottom of the collection tank 25. Drain holes 211 are formed in the bottom of the inner wall of the collection tank 25. A load-bearing plate 6 is fixedly connected to the side of the box body 1. A collection box 212 is slidably connected to the load-bearing plate 6. By providing the filter screen 210 and the drain holes 211 at the bottom of the collection tank 25, impurities or moisture generated during the dust reduction process can be effectively filtered and removed, preventing sediment or impurities from accumulating in the tank and ensuring the continuous normal operation of the equipment. At the same time, the design of the load-bearing plate 6 and the collection box 212 enhances the stability of the device. The outer wall of the motor 21 and the outer walls of the two rotating pipes 22 are connected by a sprocket chain 216. A dust collection hood is fixedly connected to the top of the rotating pipe 22. Through the driving method of connecting the motor 21 and the rotating pipe 22 by the sprocket chain 216, the power transmission of the motor 21 to the rotating pipe 22 can be realized. This transmission structure enables the rotating pipe 22 to drive the equipment to rotate efficiently, enhancing the effect of atomized dust reduction. At the same time, the dust collection hood at the top improves the collection of dust. The motor 21 drives the rotating pipe 22 to rotate, and the rotating pipe 22 drives the dust collection hood to rotate, allowing dust and air to enter the interior of the rotating pipe 22 and the diffusion port 214, achieving the collection of dust. The water tank assembly 5 includes a water tank 51, which is fixedly connected to the side of the box body 1. Water pumps 52 are fixedly connected to the top and bottom of the water tank 51 respectively. The water pumps 52 are fixedly connected to a connecting pipe 53. A drain pipe is fixedly connected to the side of the water pump 52. The top of the drain pipe is fixedly connected to the bottom of the atomizing pipe 213. A water suction pipe 54 is fixedly connected to the bottom of the water pump 52 located at the bottom of the water tank 51. The design of the water tank assembly 5 enables the arrangement of the water pumps 52 and the connecting pipe 53 to effectively provide a continuous water source for the atomizing pipe 213, effectively supporting the atomized dust reduction function. The water pumps 52 spray the water in the water tank into the interior of the diffusion port 214 through the atomizing pipe 213, mixing the dust with the water. The dust is left inside the collection tank 25 through the filter screen 210 inside the collection tank 25, achieving the separation of dust and air. The dust is collected in the collection tank 25, and the water is discharged through the drain holes 211. The rotating pipe 22 drives the extrusion block 24 to rotate, and the extrusion block 24 squeezes the first hydraulic rod 27, causing the first hydraulic rod 27 to move to the right. The pressure inside the hydraulic chamber 26 increases, driving the second hydraulic rod 29 to move upward, raising the right side of the collection tank 25, with the left side high and the right side low, causing the dust to roll towards the middle of the box body 1 and finally enter the collection box 212.

[0027] When the above-mentioned device is in specific use, the motor 21 and the negative pressure fan 23 are started. The motor 21 drives the rotary tube 22 to rotate through the sprocket chain 216. The rotary tube 22 drives the dust collection hood to rotate, and dust and air enter the inside of the rotary tube 22 and the diffusion port 214 and are discharged. At the same time, the water pump 52 is started. The water pump 52 sucks water from the inside of the water tank 51 through the connecting pipe 53, conveys the water source to the atomizing tube 213 through the drain pipe, sprays the discharged dust into the inside of the diffusion port 214 through the atomizing tube 213, drives the dust into the inside of the collection tank 25 through the water pressure, leaves the dust in the collection tank 25 through the filter screen 210 inside the collection tank 25, and discharges the water through the water discharge hole 211. When the rotary tube 22 rotates, it drives the extrusion block 24 to rotate. When the extrusion block 24 extrudes the first hydraulic rod 27 and the first hydraulic rod 27 moves to the right, the spring 28 is compressed, the pressure inside the hydraulic chamber 26 increases, driving the second hydraulic rod 29 to move upward. The second hydraulic rod 29 drives the right side of the collection tank 25 to rise, realizing that the left side of the collection tank 25 is high and the right side is low, so that the dust inside the collection tank 25 rolls towards the middle of the box body 1 and falls into the collection box 212. When the extrusion block 24 no longer extrudes the first hydraulic rod 27, the spring 28 drives the first hydraulic rod 27 to move to the left. When the first hydraulic rod 27 moves to the left, the pressure inside the hydraulic chamber 26 decreases, the second hydraulic rod 29 descends, driving the collection tank 25 to return to a flat state.

When the dust is separated from the water, the water pump 52 at the bottom of the water tank 51 is started, and the water source at the bottom of the box body 1 is extracted and recycled through the suction pipe 54.
