Technical Field

[0001] The utility model relates to the technical field of dust removal filter bags, and in particular to a dust removal filter bag that is easy to replace. Background Art

[0002] The dust collecting bag is a kind of high-efficiency dust collecting filter material, which is commonly used in cloth dust collectors. It has good ventilation performance, high dust removal efficiency, and certain acid, alkali and heat resistance. Multi-sided brushing is used in the weaving process to increase the thickness of the fabric, make it elastic, and have very good dust removal effect. The dust collecting filter bag is the heart of the dust collector during operation. Usually, the cylindrical pulse filter bag is hung vertically in the dust collector. The dust-laden gas enters the dust collector from the air inlet, passes through the guide plate of the ash hopper, so that some large particles in the gas are separated by the inertia force and fall directly into the ash hopper. The dust-laden gas enters the filter area of ​​the box body. Most of the dust is captured on the outer surface of the filter bag, and the clean gas enters the inside of the filter bag through the filter material. After the purified gas enters the upper box through the filter bag port, it is discharged from the air outlet. The cage inside the filter bag is used to support the filter bag to prevent the filter bag from collapsing. At the same time, it helps to remove and redistribute the dust cake.

[0003] However, the filter bags in the dust collector need to be replaced frequently. During replacement, some are installed with screws, but the reciprocating disassembly and installation can easily cause thread slippage, which makes the installation of the filter bags inconvenient and wastes time. Therefore, a dust filter bag that is easy to replace is needed to solve the above problems. Utility Model Content
