AI Technical Summary

Technical Problem

Existing dust suppression devices are ineffective when dealing with small areas of dust, and the vacuum cleaners need to be stopped for cleaning when handling dust, which affects work efficiency.

Method used

A device comprising a dust suppression component, a connection adjustment component, and a dust collection and cleaning component has been designed. The nozzle direction is adjusted by a telescopic connecting pipe and a movable connecting plate. Combined with a dust filter and a lifting cleaning plate, it can efficiently absorb and filter dust of different ranges and clean the dust on the filter without stopping the machine.

Benefits of technology

It improves dust suppression efficiency and applicability to different civil engineering working environments, enhances the flexibility and efficiency of the device, and avoids work interruptions caused by downtime for cleaning.

Abstract

The application discloses a dust falling device and method for civil construction, and relates to the technical field of construction dust falling.The dust falling device comprises a dust falling assembly, a connecting and adjusting assembly and a dust suction and cleaning assembly.When dust falling is performed on large-scale civil work, the water mist main nozzle and the rotating nozzle are opened, the air suction cylinder sucks air, the air guide cylinder and the auxiliary air guide pipe spray out gas to drive water mist to spray out;when dust falling is performed on small-range civil work, the rotating air guide cylinder and the air suction cylinder are rotated, the air suction cylinder air suction port is aligned with the working direction, the connecting plate is moved to drive the air suction cylinder to approach the working position, the connecting plate is moved to drive the rotating nozzle to rotate, the air suction cylinder sucks up the dust, the dustproof filter screen filters the larger dust particles in the air, the gas containing smaller dust particles passes through the water mist main nozzle and the rotating nozzle, the water mist and the dust are more fully contacted, the dust falling effect is improved, the dust falling mode is adjusted according to different civil working environments, the dust falling efficiency is improved, and the applicability of the device is improved.
