Description

Technical Field

[0001] The utility model relates to the technical field of filter bags, and more specifically, to a dust removal filter bag with a multi-layer structure. Background Art

[0002] In the existing technology, firstly, some devices cannot adjust the direction and speed of the airflow inside the filter bag, resulting in poor dust removal effect. The airflow distribution inside the filter bag is uneven, which may cause excessive filtration load in some areas, affecting the life of the filter bag. The dust removal performance cannot be optimized according to different working conditions, reducing the adaptability and flexibility of the device. Secondly, the filter bag and the mounting plate of some devices cannot be reliably fixed, and the filter bag may fall off or be installed loosely. Under working conditions such as vibration or impact, the filter bag is prone to displacement or damage, affecting the dust removal effect and device stability. The filter bag is difficult to install and remove, increasing the maintenance workload and time cost. Finally, the replacement and maintenance efficiency of the filter bags of some devices are low, and the clamping mechanism needs to be operated one by one, which is time-consuming and labor-intensive. It is impossible to achieve simultaneous loading and unloading of multiple filter bags, which increases the complexity of operation and the risk of errors. There is a lack of convenient loading and unloading methods, which is not conducive to timely replacement of worn or clogged filter bags, affecting the continuous operation of the equipment.
