Description

Technical Field

[0001] The invention relates to the technical field of construction dust reduction, and in particular to dust reduction equipment for building construction. Background Art

[0002] A lot of dust will be generated during the construction process. Construction sites are usually enclosed by fences. Installing atomizing dust reduction equipment at intervals on the fences is the current mainstream dust reduction method. The water is atomized and then contacted with the dust and adsorbed, causing the dust to fall to the ground, thus achieving the purpose of dust reduction.

[0003] However, when the existing dust reduction equipment is in use, the atomized water mist will directly fall to the ground, causing the ground on both sides of the fence to become wet. The outside of the fence is often a road, which will cause the road surface to be slippery. The water mist sprayed on the glasses of pedestrians or cyclists can easily cause blurred vision. Some construction materials are often piled on the inside of the fence, and the long-term humid environment will also have an impact on them. Especially in windy weather, the water mist is more likely to drift to the outside or inside of the fence, causing greater environmental impact. In addition, the atomizing nozzle is in a large amount of dust environment for a long time, and dust will accumulate on its surface, which can easily cause the nozzle to be blocked, requiring staff to clean and maintain it regularly. Due to the large number of atomizing nozzles installed, maintenance operations are time-consuming and laborious. Therefore, a dust reduction equipment for construction is needed to solve the above problems. Summary of the invention

[0034] The clamping assembly 5 is installed on the bracket 1 and is used to fix the dust suppression device on the construction fence; the clamping assembly 5 includes an adjusting screw 51, a clamping plate 52 and an adjusting knob 53.

Through this design, most of the water droplets formed by the combination of water mist and dust can be collected and diverted, avoiding a large amount of water droplets falling directly to the ground, thereby reducing the impact on the environment on both sides of the enclosure.

[0038] A cleaning assembly 10 is installed on the atomizing nozzle 3. The cleaning assembly 10 can clean the spray end of the atomizing nozzle 3 when the atomizing nozzle 3 rotates, and dump impurities in combination with the rotation and tilt of the atomizing nozzle 3; the cleaning assembly 10 includes a driving shaft 101, a scraper 102 and a driven bevel gear 103. The driving shaft 101 is rotatably connected to the atomizing nozzle 3 and coincides with the axis of the atomizing nozzle 3. The upper end of the driving shaft 101 is keyed to the scraper 102, and the lower end of the driving shaft 101 is keyed to the driven bevel gear 103. A driving bevel gear 104 is connected to the support plate at the lower end of the atomizing nozzle 3 through an axis, and the driving bevel gear 104 is meshed with the driven bevel gear 103. The driving bevel gear 104 is coaxially connected with a spur gear 105. A mounting frame 106 is installed on the bracket 1, and an arc-shaped rack 107 meshing with the spur gear 105 is installed on the mounting frame 106; the lower end of the scraper 102 is in contact with the upper end surface of the atomizing nozzle 3, and the rotation of the scraper 102 can scrape off the dust accumulated on the end surface of the atomizing nozzle 3, and dump the dust and impurities in conjunction with the tilted state of the atomizing nozzle 3.

[0039] The working process of the present invention is as follows:

[0040] First, engage the bracket 1 onto the enclosure, turn the adjusting knob 53 to drive the clamping plate 52 to slide, and clamp the bracket 1 on the enclosure through the clamping plate 52 and the plate surface on one side. Connect the water supply pipe to the atomizing nozzle 3, and connect the water pipe to the drainage hole 9 to complete the installation of the dust reduction equipment.

[0041] In a windless state, the atomizing nozzle 3 is in a vertical state, and water of a certain pressure is supplied into the atomizing nozzle 3. The atomizing nozzle 3 atomizes the water and sprays it vertically. The water mist contacts and absorbs the dust in the air, and falls into the box structure formed by the connecting plate 8, the water mist shielding component 6 and the bracket 1, and is discharged through the drainage hole 9, thereby preventing a large amount of water droplets from falling directly to the ground, reducing the impact on the environment on both sides of the enclosure.

[0042] When the ambient wind is toward the outside of the enclosure, the ambient wind blows the wind driving member 11 to drive the rotating shaft 4 to rotate, and the rotating shaft 4 drives the upper end of the atomizing nozzle 3 to rotate toward the inside of the enclosure, so that the water mist sprayed by the atomizing nozzle 3 can offset part of the wind force, and the water mist is dispersed to the top of the enclosure as much as possible. In the process of rotation of the atomizing nozzle 3, the rotating shaft 4 synchronously drives the driving frame 71 and the lever 72 to rotate, and the lever 72 drives the auxiliary baffle 62 on the side of the outside of the enclosure, so that the auxiliary baffle 62 extends from the main baffle 61, increases the shielding area, and reduces the water mist drifting to the outside of the enclosure. When the wind stops, the atomizing nozzle 3 is reset and rotated to a vertical state under the action of the torsion spring, and the auxiliary baffle 62 is retracted and reset under the action of gravity to avoid affecting the spray range of the atomizing nozzle 3; when the ambient wind is toward the inside of the enclosure, the atomizing nozzle 3 rotates in the opposite direction, and the water mist shielding component 6 on the other side of the bracket 1 shields the water mist, reducing the impact of the water mist on the environment on both sides of the enclosure.

[0043] When the atomizing nozzle 3 rotates, the spur gear 105 moves relative to the arc rack 107 and rotates, so that the active bevel gear 104 and the driven bevel gear 103 drive the driving shaft 101 to rotate, and the driving shaft 101 drives the scraper 102 to rotate to clean the dust accumulated on the upper end surface of the atomizing nozzle 3. The dust and impurities are dumped and removed by the rotation and tilting of the atomizing nozzle 3, eliminating the need for manual maintenance operations.
