[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Example

[0021] like Figures 1-5 As shown, this utility model provides a technical solution: a replaceable dust collector filter bag, including a treatment tank 1 and a top cover 11 fixedly installed on the top of the treatment tank 1. An air inlet pipe 16 is fixedly connected to the bottom of the treatment tank 1, and a valve 17 is fixedly installed on the air inlet pipe 16. An air outlet pipe 18 is fixedly connected to the top of the top of the top of the treatment tank 1. A circular mounting plate 12 is fixedly connected to the inner side wall of the top of the treatment tank 1. The circular mounting plate 12 has multiple mounting holes 13. Dust collector filter bags 14 are inserted into the inner side of each mounting hole 13. Fixed filter cartridges 15 are inserted into the inner side of each of the multiple dust collector filter bags 14. A fixing component 2 for pressing the fixed filter cartridges 15 is provided above the multiple fixed filter cartridges 15. Specifically, in use... During operation, the system first draws in gas containing dust particles through the inlet pipe 16. Valve 17 is used to control the airflow or shut off the airflow so that gas treatment can be stopped or maintenance can be performed when necessary. The drawn-in gas enters the interior of the treatment tank 1. The dust filter bags 14 serve as the filter medium. Their design allows gas to pass through while dust particles are captured on the surface of the filter bags. These filter bags are mounted on the circular mounting plate 12 through the mounting holes 13, ensuring that they are stably and evenly distributed inside the treatment tank 1. This helps to evenly distribute the airflow and reduce the wear of the filter bags. To further enhance the dust removal effect and the stability of the filter bags, a fixed filter cartridge 15 is provided in the device. These fixed filter cartridges 15 are inserted into the dust collector filter bag 14. By increasing support and limiting the expansion of the filter bag, the filter bag is effectively prevented from being excessively deformed or damaged by airflow impact. Furthermore, by setting the fixing component 2 to press the fixed filter cartridges 15, a tight contact between the fixed filter cartridges 15 and the dust collector filter bag 14 and the mounting plate is ensured. This tightness is used to prevent gas from flowing out directly around the filter bag, ensuring the effectiveness and efficiency of the dust removal process. Finally, the gas that has undergone dust removal is discharged through the exhaust pipe 18.

[0022] As one implementation method in this embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, the fixing assembly 2 includes a connecting circular plate 21. Multiple fixing brackets 22 are fixedly connected to the lower end face of the connecting circular plate 21. The bottom ends of the multiple fixing brackets 22 are fixed to the upper end face of the corresponding fixing filter cartridge 15. A snap-fit ​​device 3 for assisting in fixing the connecting circular plate 21 is provided on the upper end face of the connecting circular plate 21. This snap-fit ​​device 3 facilitates the limiting and fixing of the connecting circular plate 21 and facilitates the quick assembly and disassembly of the dust collector filter bag 14. The snap-fit ​​device 3 includes a mounting shell 31 fixedly installed on the upper end face of the connecting circular plate 21. A rotating rod 32 is rotatably connected to the center of the inner top wall of the mounting shell 31. The bottom end of the rotating rod 32 extends into the inner side of the mounting shell 31 and is fixedly connected to the end of a cam 33. A rotating disk 34 is fixedly connected to the top end of the rotating rod 32. A ring array is mounted on the rotating disk 34. The mounting housing 31 has multiple positioning holes 341, and a threaded hole 311 is provided on the upper surface of the mounting housing 31. A positioning rod 35 adapted to the threaded hole 311 is vertically inserted into the positioning hole 341. Sliding openings 312 are provided on the opposite side walls of the mounting housing 31, and a rod 36 is inserted into the inner side of each sliding opening 312. A contact plate 37 is fixedly connected to one end of the rod 36 near the cam 33. A return spring 38 is provided between the contact plate 37 and the inner wall of the mounting housing 31. Insertion frames 39 adapted to the rod 36 are fixedly connected to the opposite side inner walls of the processing tank 1. One end of the return spring 38 is fixed to the contact plate 37, and the other end of the return spring 38 is fixed to the inner wall of the mounting housing 31. In actual use, when it is necessary to fix the circular plate 21, the operator first... Rotating the rotating disk 34 rotates the rotating rod 32 and the cam 33. As the cam 33 rotates, it gradually approaches the insertion rod 36 inside the mounting housing 31. Since the insertion rod 36 is connected to the return spring 38 through the abutment plate 37, when the protruding part of the cam 33 contacts the abutment plate 37, it pushes the abutment plate 37 and the insertion rod 36 outward until the insertion rod 36 is fully inserted into the insertion frame 39 on the inner wall of the processing tank 1. At this time, the cooperation between the insertion rod 36 and the insertion frame 39 plays a limiting and fixing role, ensuring the stable installation of the connecting circular plate 21 (and the fixed filter cartridge 15 and dust filter bag 14 connected to it) inside the processing tank 1. At the same time, since the positioning hole 341 on the rotating disk 34 corresponds to the threaded hole 311 at the upper end of the mounting housing 31, The operator can vertically insert the positioning rod 35 into the positioning hole 341 and screw it into the threaded hole 311. In this way, the positioning rod 35 further fixes the rotating disk 34, preventing loosening due to vibration or misoperation. When it is necessary to disassemble the dust filter bag 14, first pull out the positioning rod 35 to release the fixation of the rotating disk 34, and then rotate the rotating disk 34 in the opposite direction to rotate the cam 33. As the cam 33 gradually moves away, the return spring 38 will push the abutment plate 37 and the insertion rod 36 to move inward until the insertion rod 36 is completely pulled out of the insertion frame 39. At this time, the connecting circular plate 21 and all its components can be easily removed, realizing the quick disassembly and stable fixation of the dust filter bag 14, which greatly improves the maintainability and usage efficiency of the equipment.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
