Fixing bolts 13 are threadedly connected to the inner surface walls of the two fixing holes 12, and the outer surfaces of the two fixing bolts 13 are movably inserted into the inside of the two through holes 10.

[0024] The effect achieved by the entire Embodiment 1 is that when it is necessary to install the anti - fracture cage bone 3 inside the dust - removal filter bag body 1, first open the dust - removal filter bag body 1. Since the positioning column 2 is fixedly installed at the bottom of the inner wall of the dust - removal filter bag body 1, and then a cross - shaped positioning frame 4 is fixedly installed at the bottom of the anti - fracture cage bone 3, and a positioning hole 5 is also opened on the positioning frame 4. Through the action of the positioning hole 5 and the positioning column 2, the anti - fracture cage bone 3 can be accurately placed at the corresponding position inside the dust - removal filter bag body 1. Also, because a circular slot 6 is opened at the top of the anti - fracture cage bone 3, and the circular insertion ring 7 installed at the bottom of the installation ring 8 is inserted into the circular slot 6. Then, two first fixing blocks 9 are fixedly installed on the outer wall of the installation ring 8, and through holes 10 are opened on both of the two first fixing blocks 9. Since two second fixing blocks 11 are fixedly installed on the outer wall of the dust - removal filter bag body 1, and fixing holes 12 are opened on both of the two second fixing blocks 11. When the two through holes 10 and the two fixing holes 12 correspond to each other, through the action of two fixing bolts 13, the two fixing bolts 13 pass through the through holes 10 on the two first fixing blocks 9 and then are threadedly connected inside the two fixing holes 12, thereby fixedly connecting the installation ring 8 and the dust - removal filter bag body 1 together. And the anti - fracture cage bone 3 can be quickly and accurately installed inside the dust - removal filter bag body 1, and it is convenient for disassembly and assembly, thus improving the disassembly and assembly efficiency of the anti - fracture dust - removal filter bag.

[0026] The effect achieved by the entire Embodiment 2 is that through the action of providing the high - temperature - resistant layer filter bag 14 on the inner wall of the dust - removal filter bag body 1, the high - temperature - resistant layer filter bag 14 is made of fiberglass material and can withstand temperatures above 260 °C. It is a popular choice in high - temperature applications. Its thickness is generally between 0.3 mm and 1.0 mm, mainly used to bear the filtration of high - temperature gases and avoid the degradation or failure of the filter bag in a high - temperature environment. Then, a corrosion - resistant layer filter bag 15 is provided on the inner wall of the high - temperature - resistant layer filter bag 14. The corrosion - resistant layer filter bag 15 is made of polyvinyl fluoride material and has extremely strong corrosion resistance, suitable for a variety of chemicals. Its thickness is generally between 0.2 mm and 0.5 mm, which can effectively protect the dust - removal filter bag from damage by the filtered object, thereby extending the service life of the dust - removal filter bag and further improving the use effect of the anti - fracture dust - removal filter bag.

At the same time, the dust removal filter bag is also protected from damage by the filtered object, and the service life of the dust removal filter bag is extended. Then, since the positioning column 2 is fixedly installed at the bottom of the inner wall of the dust removal filter bag body 1, and the anti-fracture cage bone 3 can be accurately placed at the corresponding position inside the dust removal filter bag body 1 through the positioning frame 4 and the positioning hole 5. Then, the circular insertion ring 7 installed at the bottom of the installation ring 8 is inserted into the circular slot 6 opened at the top of the anti-fracture cage bone 3. At this time, the two first fixing blocks 9 installed on the outer wall of the installation ring 8 correspond to the two second fixing blocks 11 installed on the outer wall of the dust removal filter bag body 1. Since through holes 10 are opened on both of the two first fixing blocks 9 and fixing holes 12 are opened on both of the two second fixing blocks 11, through the action of two fixing bolts 13, they pass through the two through holes 10 and are then threadedly connected to the inside of the two fixing holes 12, thereby fixedly connecting the installation ring 8 and the dust removal filter bag body 1 together, and the anti-fracture cage bone 3 can be quickly fixedly installed inside the dust removal filter bag body 1. The whole process is convenient for disassembly and assembly, thus improving the disassembly and assembly efficiency of the anti-fracture dust removal filter bag, and further improving the use effect of the anti-fracture dust removal filter bag.
