Description

Technical Field

[0001] The utility model relates to the technical field of dust removal bag cages, and more specifically, it relates to a dust removal bag cage with good installation stability. Background Art

[0002] In the existing technology, the dust removal bag cages in the prior art have deficiencies in terms of installation stability. These cages often exhibit instability after installation in the dust collector due to design flaws or improper material selection. This instability may manifest as deformation, loosening of the cage, or insecure connection with the filter bag, thus affecting the normal operation of the dust collector. In addition, the installation process of the existing cages is usually cumbersome, requiring a lot of time and labor, which undoubtedly reduces work efficiency and increases operating costs.

This fixed-length design limits the applicable range of the cage, resulting in suboptimal matching in specific dust collectors or filter bag systems. In addition, the cage with unadjustable length may lead to loose installation of the filter bag, affecting the dust removal effect. Summary of the Utility Model
