AI Technical Summary

Technical Problem

The existing road and bridge construction dust reduction equipment is inconvenient to be installed on the construction site, and the spray range is limited, resulting in low dust reduction efficiency and serious waste of water resources.

Method used

A dust reduction device including a fog cannon machine and multiple dust removal auxiliary equipment was designed. The dust removal auxiliary equipment consists of a spiral filter cartridge and a vacuum mount. The working mode is controlled by a speed sensor to realize dust removal and cleaning mode, improve dust filtration efficiency, and Convection technology reduces water mist evaporation and increases the contact time between water mist and dust.

Benefits of technology

It improves the coverage and efficiency of dust reduction equipment, reduces waste of water resources, is easy to install and transport, reduces costs, and enhances dust filtration capabilities.

Abstract

The present invention relates to the technical field of air dust separation, and specifically to a dust reduction device for road and bridge construction, which includes a plurality of dust removal auxiliary devices, wherein the support rod of the dust removal auxiliary device is spliced ​​by spiral filter cartridges, and the rotation of the spiral filter screen in the spiral filter cartridge is controlled by a motor, and the working mode of the dust removal auxiliary device is changed according to the decreasing trend of the speed sequence of the spiral filter screen, and the working mode includes a dust removal mode and a cleaning mode, wherein the motor rotates in the positive direction in the dust removal mode, and the speed of the motor is positively correlated with the difference in the speed in the speed sequence; and the motor rotates in the reverse direction in the cleaning mode, and water is injected into the spiral filter cartridge from bottom to top at the same time, and the speed of the motor is positively correlated with the mean of the speed sequence. The present invention further improves the dust removal efficiency of the dust removal device.
