[0002] Dust filter bags are highly effective filter media with excellent ventilation, high dust removal efficiency, and resistance to acids, alkalis, and heat. Multi-sided brushing is used during the weaving process to increase fabric thickness and elasticity, resulting in excellent dust removal performance and a high dust removal rate. Dust filter bags are made from polyester staple or long fibers, and their service life is generally 4-6 times that of fiberglass fabrics. They offer excellent air permeability, a high dust collection rate, and are easy to clean.

[0003] The filter bag of claim 1, wherein the bottom central wall of the filter bag is connected to the upper filter cartridge, the bottom end of the outer wall of the upper filter cartridge is sleeved with the lower filter cartridge, and the top inner walls on both sides of the lower filter cartridge are provided with supporting blocks, the top outer walls of the supporting blocks are in contact with the bottom outer wall of the upper filter cartridge, the bottom outer walls of the upper filter cartridge are provided with connecting grooves on the left and right bottom outer walls of the upper filter cartridge, the top outer walls of the lower filter cartridge are provided with openings on the left and right top outer walls of the lower filter cartridge, and the inner cavities of the openings are plugged with connecting blocks, one end of the connecting block close to the upper filter cartridge is inserted into the inner cavity of the connecting groove, and the outer wall of the connecting block is sleeved with a spring. In the utility model, the connecting block is pulled outward in the device to remove the connecting block from the connecting groove, so that the fixed connection between the upper filter cartridge and the lower filter cartridge is disconnected, so that the upper filter cartridge and the lower filter cartridge can be separated by simply removing the connecting block from the connecting groove, thereby reducing the difficulty of disassembling the device and facilitating cleaning of the lower filter cartridge.

[0004] However, the above method still has the following defects: the upper filter cartridge and the lower filter cartridge are disassembled from each other by simultaneously stretching the connecting blocks; but in the actual operation, the user is required to operate the two connecting blocks accurately and synchronously to ensure that they can move smoothly towards each other and accurately align with the connecting groove. This process invisibly increases the complexity of the operation, brings inconvenience to the user when replacing the filter bag, and may delay the progress of maintenance work and affect the overall efficiency.

[0009] As a preferred technical solution of the present invention, one end of the insertion rod passes through the card box and is provided with a pull cap, and a slot that slides with the insertion rod is opened in the middle of the card box.

[0010] As a preferred technical solution of the present invention, the limiting assembly includes a moving rod, which is slidably arranged at the top of the card box, and a support plate is provided at the bottom end of the moving rod. The bottom end of the support plate is fixedly connected to the top end of the limiting rod, and a spring is provided between the support plate and the card box, and a spring set is provided on the outside of the moving rod. The top end of the moving rod passes through the card box and extends to the outside of the card box.

[0014] Compared with the related art, the multi-tube combined dust filter bag provided by the utility model has the following beneficial effects:

[0015] By setting a limit assembly, the pressure handle is used to drive the swing rod to swing, and combined with the swing groove, the movable rod can be moved in the vertical direction, so that the limit rods and the limit holes that are plugged into each other are separated from each other. By using the pull cap to drive the insertion rod to move horizontally, under the action of spring 1, the user can loosen the pressure handle to make the limit rod and the other limit hole plug into each other, which changes the cumbersome requirement of synchronously aligning multiple insertion rods with the insertion holes in traditional operations, and instead firmly limits the insertion rods one by one and easily. This process reduces the complexity of the operation, makes it more convenient for users to replace filter bags, improves the progress of maintenance work, and ensures the overall efficiency of filter bag disassembly and assembly.
