Description

Technical Field

[0001] This utility model relates to the field of dust suppression devices, and more specifically, to a dust suppression device for the demolition and construction of steel box girder bridges. Background Technology

[0002] Bridges generally refer to structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. The construction and demolition of bridges generate a large amount of dust, so it is necessary to spray a large amount of water on the demolition site to reduce dust and particles around the demolition site. However, existing dust suppression mechanisms generally spray a large amount of water onto the steel box girder demolition site, which leads to a waste of water. Furthermore, directly spraying the aqueous solution reduces the space covered by the water, resulting in a decrease in dust suppression efficiency. Therefore, I have proposed a dust suppression device for the demolition and construction of steel box girder bridges. Utility Model Content

By adjusting the connection angle between the connecting ball and the limiting cover, the tilt angle of the mist exhaust pipe can be easily adjusted, thereby facilitating the spraying of water mist onto the steel box girder. Furthermore, by using accessories to spray water mist onto the steel box girder bridge, the space covered by the water mist near the steel box girder bridge is increased, thus facilitating the condensation of water mist and dust, thereby improving the dust suppression efficiency.

The atomizing plates 4 can be any existing solid with a volume less than 0.2 cubic meters. Two symmetrically arranged support frames 5 are mounted on the upper end of the base 1. Limiting shafts 6 are installed on the opposing side walls of the two support frames 5. The limiting shafts 6 are rotatably connected to... The exhaust pipe 7 has multiple arrayed exhaust holes 8 on its side wall. A screening screen 9 is installed at the lower end of the exhaust pipe 7. A serpentine pipe 10 is installed at the upper end of the water storage tank 3 and the lower end of the exhaust pipe 7. A limit cover 11 is installed on the side wall of the exhaust pipe 7. A bracket 13 is installed on the side wall of the two support frames 5. A threaded rod 14 is threadedly connected to the bracket 13. A docking ball 12 is installed on the side wall of the threaded rod 14. The docking ball 12 is rotatably connected to the limit cover 11. A blower 15 is installed on the inner wall of the exhaust pipe 7.

[0025] An air inlet is provided at the lower end of the exhaust pipe 7, and a screening screen 9 is installed on the inner wall of the air inlet, so that the blower 15 can draw in outside air through the air inlet and the screening screen 9 can screen the incoming air.

[0026] The serpentine tube 10 connects the inner cavity of the mist exhaust pipe 7 and the inner cavity of the water storage tank 3. The side wall of the water storage tank 3 is equipped with an inlet pipe and a drain pipe, and the side walls of the inlet pipe and the drain pipe are equipped with control valves, so that the atomizing plate 4 can discharge the water mist in the water storage tank 3 into the serpentine tube 10 and into the mist exhaust pipe 7.

[0027] The side wall of the exhaust pipe 7 is provided with a rotating hole, and the limiting shaft 6 is rotatably connected to the rotating hole to facilitate the rotation of the exhaust pipe 7, thereby adjusting the angle of the exhaust pipe 7.

[0029] In use, a technician in the field adds water to the inner cavity of the water storage tank 3 through the water inlet pipe. Then, the threaded rod 14 is rotated spirally. The threaded rod 14 drives the limiting cover 11 through the connecting ball 12 to adjust the angle of the mist exhaust pipe 7, so that the mist exhaust hole 8 faces the road. Then, the atomizing plate 4 and the blower 15 are started. The atomizing plate 4 atomizes the water in the water storage tank 3, so that the water in the water storage tank 3 can enter the mist exhaust pipe 7 through the serpentine pipe 10. At this time, the blower 15 blows the water mist and air into the inner cavity of the mist exhaust pipe 7, and blows the water mist to the steel box girder of the road through the mist exhaust hole 8.
