[0010] Further, the filter bag fixing assembly comprises a round surface shell embedded in the side wall of the support flower plate, an outer support framework is embedded in the inner side wall of the top of the round surface shell, a filter bag is arranged on the inner side wall of the top of the outer support framework, and two groups of fixing members of the same structure are embedded in the inner cavities of the two sides of the round surface shell.

[0011] Further, the fixing member comprises a square shell embedded in the inner cavity of one side of the round surface shell, a support plate is arranged on the side wall of the inner cavity of the square shell, a sliding sleeve is arranged on the outer wall of one side of the support plate, a pressing rotary round rod is slidingly connected to the inner side wall of the sliding sleeve, the two ends of the pressing rotary round rod extend to the outer side wall of the square shell, a round surface abutting block is arranged on the outer side wall of the inner cavity of the square shell adjacent to the pressing rotary round rod, a spring is arranged on the outer side wall of one end of the sliding sleeve adjacent to the pressing rotary round rod, and an abutting vertical block is arranged on the other end of the pressing rotary round rod.

[0012] Further, the filter bag comprises two sides, which are symmetrically clamped with abutting hollow clamping grooves matched with the pressing rotary round rod and the abutting vertical block arranged on the other end of the pressing rotary round rod, and an inner support framework is arranged on the side wall of the inner cavity of the filter bag.

[0013] Further, the side walls of the support plate and the round surface abutting block are provided with two groups of rotary bearings of the same structure, and the side walls of the two groups of rotary bearings are connected to the two ends of the spring.

[0014] Further, the abutting hollow clamping groove comprises a rubber friction coating arranged on the inner side wall.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model facilitates quick disassembly, replacement, and installation of the filter bag through the filter bag fixing assembly, enabling rapid disassembly, replacement, and installation even when the filter bag is damaged or broken, thus improving the efficiency of filter bag replacement and installation for operators. During disassembly, replacement, and installation, the operator manually opens the filter chamber by opening a sealed hinged door on one side wall. Multiple filter bag fixing assemblies of the same structure are arrayed and embedded on the side wall of the supporting plate. The inner cavities on both sides of the circular shell included in the filter bag fixing assembly are each embedded with two sets of identical fixing members. The filter bag is placed into the inner wall of the outer support frame for support, and the operator simultaneously manually presses both sets of pressing and rotating rods to drive the filter bag. A circular abutment block is located on the outer wall of the inner cavity of the square shell. This block slides towards one end of the filter bag along the inner wall of the sliding sleeve. Simultaneously, two sets of identical rotating bearings are located on the side walls of both the support plate and the circular abutment block. As the circular abutment block slides towards the filter bag, it compresses the spring, causing both sets of pressing and rotating rods to drive the vertical abutment blocks at their other ends to extend towards the filter bag and align with the filter bag. Symmetrical hollow abutment grooves matching the pressing and rotating rods and the vertical abutment blocks at their other ends are located on both sides of the filter bag. Manual rotation causes both sets of pressing and rotating rods to rotate together along the inner wall of the sliding sleeve via the side walls of the two sets of rotating bearings, which are connected to the two ends of the spring. This causes the vertical abutment blocks at the other ends of the pressing and rotating rods to change from a vertical to a horizontal orientation. Releasing the two sets of... Pressing the rotating rod causes a spring to spring back one end of the rod, which is adjacent to a circular abutment block on the outer wall of the square shell's inner cavity. This causes the other end of the rotating rod, with its vertical abutment block, to abut against the matching hollow abutment groove, achieving quick and easy fixation. The hollow abutment groove has a rubber friction coating on its inner wall to increase friction and prevent the vertical abutment block on the other end of the rotating rod from loosening within the matching hollow abutment groove. The inner support frame is then inserted into the inner wall of the filter bag for support and tautness, completing the installation. For disassembly, the same steps are repeated, except the vertical abutment block on the other end of the rotating rod is changed from a vertical to a horizontal position, disengaging from the matching hollow abutment groove, thus completing the filter bag removal. The design facilitates quick disassembly, replacement, and installation of the filter bags, enabling rapid removal and replacement even when the filter bags are damaged or broken. This improves the efficiency of filter bag replacement and installation for operators. When the pulse dust collector is in operation, dust-laden gas enters the filter chamber through an air inlet located on one side wall at the bottom. The gas passes through the filter bags, and the dust is trapped on the surface of the filter bags. The purified gas then passes through the filter bags into the clean air chambers spaced at the top of the filter chamber and is discharged from the air outlet. When cleaning is required, high-pressure air is injected through the jet pipe of the pulse dust collector, which extends to the top of the filter bag fixing assembly. This causes the filter bags to expand and vibrate instantaneously, shaking off the dust adhering to the surface of the filter bags and allowing it to fall into the funnel at the bottom of the filter chamber for recycling.
