AI Technical Summary

Technical Problem

After the air purification device is operating for a long time, the filter filter element is easily blocked due to accumulated dust and tiny particles, and the disassembly process is cumbersome, which increases the time cost of maintenance and replacement of the filter element and affects the maintenance efficiency.

Method used

A mobile air purification device is designed, including an anti-blocking cleaning structure, which drives the fixing plate and the cleaning brush plate to rotate by a motor, scratch, squeeze and knock the filter ring to remove accumulated dust and particles, and collect it into the pull-out collection box through a collection funnel and connecting pipe, for easy regular cleaning. At the same time, the device is simple to design, which is convenient for disassembly and maintenance.

Benefits of technology

It effectively avoids clogging of the filter element, simplifies the maintenance and replacement process, reduces time costs, and improves overall maintenance efficiency.

Abstract

The utility model relates to a movable air purification device used in tunnel construction, which comprises an air purification equipment box body, and an anti-blocking cleaning structure is arranged in the air purification equipment box body. The air purification structure comprises a fixing ring, a fixing rod, a sponge filter ring, a glass fiber filter ring, an insertion base, a first fan, a fan cover and a second fan. According to the movable air purification device, when a sponge filter ring and a glass fiber filter ring run for a long time and dust and tiny particulate matter are accumulated, a motor drives a fixing plate and a cleaning brush plate to rotate, and the sponge filter ring and the glass fiber filter ring are scraped, extruded and beaten through the cleaning brush plate; accumulated dust and tiny particles fall off from the sponge filter ring and the glass fiber filter ring, are collected by the collecting funnel in the natural sinking process, and are collected in the drawing type collecting box through the connecting pipe, so that blockage can be effectively avoided.
