AI Technical Summary
Technical Problem
The air inlet design of the filter cartridge in existing dust removal devices leads to turbulence and uneven filtration, resulting in poor backflushing cleaning effect, easy clogging of the filter cartridge, and affecting filtration efficiency and service life.
Method used
It adopts a movable dust collector filter cartridge design, which uses a ball screw to drive the filter body to stretch and twist, thereby increasing the filtration area and dust removal effect and avoiding filter cartridge clogging.
Benefits of technology
It improves the filtration efficiency and backflushing cleaning effect of the filter cartridge, extends the service life of the filter cartridge, and reduces the risk of filter cartridge clogging.

Abstract
The application relates to a movable dust-removing filter cylinder and a dust-removing device. The dust-removing filter cylinder comprises a filter body and a lead screw. Open side end covers and closed side end covers are arranged at both ends of the filter body. The lead screw is horizontally arranged in the filter body and is screw-connected to the middle part of the closed side end cover. The filter body comprises a plurality of elastic pleats. The plurality of pleats are sequentially connected to form a circular closed loop. The lead screw is located on the axis of the circular closed loop. The two ends of the pleats are connected to the open side end cover and the closed side end cover respectively. An acute angle is formed between the pleats and the lead screw. When back-flushing, high-speed airflow impacts on the closed side end cover. The closed side end cover rotates around the lead screw and simultaneously moves linearly along the lead screw. The pleats of the filter body are stretched along the extension direction of the lead screw. The axial length and the filtering surface area of the filter body are increased. The dust accumulated on the upper part of the filter body is more easily blown away by the back-flushing airflow. The one-side stretching and twisting of the filter body more effectively shakes off the dust accumulated on the upper part of the filter body. The dust accumulated on the upper part of the filter body is avoided. The back-flushing effect is improved.
