Description

Technical Field

[0001] This utility model relates to the field of multi-level combined filter bag technology, specifically, to a multi-level combined filter bag. Background Technology

[0002] Dust collector filter bags are a type of high-efficiency dust collection material, characterized by good air permeability, high dust collection efficiency, and certain resistance to acids, alkalis, and heat. The weaving process employs multi-sided napping, increasing the fabric thickness and elasticity, resulting in excellent dust collection performance. However, to enhance the structural strength and filtration efficiency, multi-layered dust collector filter bags are typically used. Currently, in practical use, fine dust particles easily penetrate the filter bag and enter the gaps between adjacent filter layers, clogging the bag, affecting dust collection efficiency, and hindering subsequent cleaning. Existing filter bags require complete replacement after damage, which is wasteful. Furthermore, the connection between the filter bag and the housing is difficult to clean, leading to poor cleaning results.

[0003] In view of this, a multi-stage combined filter bag is provided to overcome the above-mentioned defects. Utility Model Content
