Spray and aspirating device for construction in construction site

Abstract

The invention discloses a spray dust suppression device for construction on a construction site, which includes a spray dust suppression machine, the spray dust suppression machine includes a spray tube, a bracket and an installation box connected in sequence, the side wall of the spray tube is connected to the bracket in rotation, and the bracket will The spray tube supports the top of the installation box, and a support plate is provided on the side wall of the spray tube near the end of the installation box. The support plate is parallel to the axis of the spray tube, and the end of the support plate away from the spray tube is an arc surface. The axis of the arc-shaped surface coincides with the rotation axis of the spray tube, and the arc-shaped surface is in contact with the end surface of the installation box close to the spray tube. No matter how the spray tube rotates, the arc-shaped surface on the support plate is always in contact with the installation box, and bears part of the weight of the spray tube to reduce the stress on the rotating part between the spray tube and the bracket, so as to improve the long-term use of the intermediate shaft and The coaxiality between the matching holes protects the quality of the bearing and facilitates the adjustment of the angle of the water mist sprayed by the fog and dust suppressor.

Description

Technical field [0001] The invention relates to a spray dust reduction machine, in particular to a spray dust reduction device for construction on a construction site. Background technique [0002] Spray dust reduction is a new type of dust reduction technology. Its principle is to use the particles produced by spray due to their small size and basically zero surface tension. When sprayed into the air, they can quickly absorb dust particles of various sizes in the air, forming effective control. dust. It has a good effect on dust control in large open areas. At the same time, this effect is completely an atomization effect, never producing water droplets and moisture. It is especially suitable for a wide range of applications such as construction sites, foundries, textile factories, food factories, printing plants, airports, playgrounds, pedestrian streets, etc., with low cost and obvious effect. [0003] The principle of the spray dust suppressor is to use a high-pressure pump ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a spray dust suppression device for construction on a construction site, which solves the problem that when the overall weight of the spray cylinder is only supported by the rotating part, not only will the rotating part be subjected to great stress, but also the coaxiality between the rotating shaft and the matching hole will occur. change, or even damage the bearings on the shaft
