[0002] The dust filter bag is the core component of the dust collector, which is mainly used to capture solid particles in dust-laden gas to purify the gas or recover useful solid matter.

[0003] Under certain circumstances, dust filter bags may be subject to mechanical shock or vibration, impacted and rubbed by high-speed dust particles, causing surface wear. This can lead to damage or seal failure, allowing dust particles to escape through the damaged areas, significantly reducing dust removal efficiency. This can affect the overall performance of the dust collector and may also cause the emitted dust concentration to exceed the standard, causing environmental pollution.

[0004] Therefore, it is necessary to invent a dust filter bag with a protective mechanism to solve the above problems. Utility Model Content
