[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment: a gas impurity filtering pipe, including a filter pipe body 1, a gas pipe 2, and an anti-loosening sleeve 3. A connecting plate 4 is fixedly installed on both the filter pipe body 1 and the gas pipe 2. A connecting hole 5 is provided on the side of the connecting plate 4, and a receiving groove 6 is provided on the connecting hole 5. A locking seat 7 is fixedly installed at one end of the anti-loosening sleeve 3, and an anti-loosening sleeve 8 is provided at the other end of the anti-loosening sleeve 3. A locking block 9 is fixedly installed at the end of the anti-loosening sleeve 8 away from the anti-loosening sleeve 3. Locking slots 10 are provided at both ends of the locking seat 7, and movable cavities 11 are provided at both ends of the locking block 9. A return spring 12 is fixedly installed inside the movable cavity 11, and a locking rod 13 is fixedly connected to the return spring 12.

A connecting rod 17 is fixedly installed on both the disk 15 and the filter disk 16, and a support ring 18 is fixedly installed on the connecting rod 17.

[0024] Please see Figures 1-3 In this embodiment, the connecting holes 5 and the receiving grooves 6 are arranged in a circular array. The first anti-loosening sleeve 3 and the second anti-loosening sleeve 8 are both adapted to the connecting plate 4. The first anti-loosening sleeve 3 and the second anti-loosening sleeve 8 are rotatably connected. The locking seat 7 is engaged with the locking block 9. The locking rod 13 is pinned to the locking groove 10. The end of the locking rod 13 away from the return spring 12 is provided with a pressing slope. The locking rod 13 is slidably connected to the movable cavity 11. A connecting pull rod 19 is fixedly installed at the front end of the locking rod 13. The upper end of the connecting pull rod 19 extends to the outside of the movable cavity 11 and is connected to the movable cavity. 11. Sliding connection: The filter tube 1 and the gas pipeline 2 are connected by special bolts, which makes it easy to keep the side of the bolt flush with the receiving groove 6. The anti-loosening sleeve 1 3 and anti-loosening sleeve 2 8 are fitted onto the fixed connecting plate 4. At the same time, the anti-loosening sleeve 1 3 and anti-loosening sleeve 2 8 can lock the side of the bolt structure, and make the locking block 9 and the locking seat 7 engage with each other. The return spring 12 drives the locking rod 13 to insert into the locking groove 10, thereby locking the anti-loosening structure and resisting the bolt, preventing the bolt connection structure from loosening. This helps to improve the stability of the gas impurity filter pipeline installation.

[0025] Please see Figures 4-5 In this embodiment, a filter screen 20 is fixedly installed inside the filter disc 16. Air holes 21 are opened on the disk 15 and are evenly spaced. The support ring 18, disk 15, and filter disc 16 are all slidably connected to the mounting groove 14. The connecting rods 17 are arranged in a ring array. A sealing ring 22 is fixedly installed on the support ring 18. The connecting disc 4 and the sealing ring 22 are fitted together, allowing the disk 15 and filter disc 16 to be easily slidably inserted into the two mounting grooves 14. After connecting the filter tube body 1 and the gas pipeline 2, the connecting disc 4 fits against the support ring 18 and the sealing ring 22, thereby achieving the locking and fixing of the disk 15 and filter disc 16, realizing the filtration function. The sealing ring 22 can further improve the sealing performance at the pipeline connection. The filter structure is simple and practical, convenient for installation and disassembly / replacement, and improves the ease of use of the gas impurity filtration pipeline.

[0026] During operation, the filter tube 1 and gas pipeline 2 are connected with dedicated bolts to ensure the bolt edges are flush with the receiving groove 6. Anti-loosening sleeves 3 and 8 are fitted onto the fixed connecting plate 4, simultaneously securing the bolt structure and allowing the locking block 9 to engage with the locking seat 7. The return spring 12 drives the locking rod 13 into the locking groove 10, locking the anti-loosening structure and preventing bolt loosening. This improves the stability of the gas impurity filter pipeline installation. The disk 15 and filter disc 16 are easily slidably installed into the two mounting slots 14. After connecting the filter tube 1 and gas pipeline 2, the connecting plate 4 abuts against the support ring 18 and sealing ring 22, securing the disk 15 and filter disc 16 and achieving the filtering function. The sealing ring 22 further enhances the sealing performance at the pipeline connection. The filter structure is simple and practical, facilitating installation, disassembly, and replacement, thus improving the ease of use of the gas impurity filter pipeline.

[0027] Through the above steps, the filter tube body 1 and the gas pipeline 2 are fixedly connected by special bolts, keeping the side of the bolt flush with the receiving groove 6. The anti-loosening sleeve 1 3 and anti-loosening sleeve 2 8 are fitted onto the fixed connecting plate 4 to easily lock the side of the bolt structure and hold the bolt in place. This solves the problem that the bolt connection structure may loosen after long-term use of the gas impurity filter pipeline, which is not conducive to improving the stability of the gas impurity filter pipeline installation.
