The filtering mechanism 2 comprises a pipe body 21, and the pipe body 21 is attached to the inner wall of the heat preservation pipe body 1; the pipe body 21 is internally and fixedly connected with a primary filter screen 22, and the primary filter screen 22 is positioned at one end of the pipe body 21 far away from the liquid inlet 11. One end of the pipe body 21, which is far away from the primary filter screen 22, is provided with an annular plate 211 which gradually inclines towards the center of the pipe body 21, one end of the annular plate 211, which has a smaller diameter, is located inside the pipe body 21, and one end of the annular plate 211, which has a smaller diameter, is fixedly connected with a secondary filter screen 23. The diameter of the filtering holes of the primary filtering net 22 is smaller than that of the filtering holes of the secondary filtering net 23.

When the liquid medium in the insulating tube body 1 flows, the liquid medium flows through the second-stage filter screen 23, the second-stage filter screen 23 filters the liquid medium for the first time, and the filtered impurities remain on the second-stage filter screen 23. The filtered liquid medium flows through the secondary filter screen 23 to the primary filter screen 22, and the primary filter screen 22 performs secondary filtration on the liquid medium when the liquid medium flows through the primary filter screen 22. The liquid medium passes through the filtration of second grade filter screen 23 and one-level filter screen 22 in proper order, reduces the possibility of remaining impurity in the liquid medium, improves the circulation efficiency of liquid medium in the insulating tube body 1.

When the liquid medium in the insulating tube body 1 flows, the anti-drop block 41 plays a limiting role on the tube body 21, and the possibility that the tube body 21 moves in the insulating tube body 1 due to the flowing effect of the liquid medium is reduced.

A pull ring 5 is fixedly connected to a side surface of the baffle plate 27 away from the pipe body 21, and the pull ring 5 can enable an operator to take out the filter mechanism 2 more conveniently. When the impurities in the dirt storage pipe 25 are fully collected and the filtering mechanism 2 needs to be taken out and cleaned, the handle 33 is pulled in the direction away from the pipe body 21, the handle 33 and the short rod 32 drive the pin body 31 to move in the direction outside the heat preservation pipe body 1 until one side surface of the pin body 31 connected with the short rod 32 is abutted to the bottom wall of the groove 12, the pin body 31 is integrally positioned in the groove 12 at the moment, and the pin body 31 does not limit the pipe body 21 any more. Then holding the pull ring 5, pulling the pipe body 21 towards the direction close to the liquid inlet 11 until the pipe body 21 is separated from the insulating pipe body 1.

The implementation principle of the insulating tube with the filtering function in the embodiment of the application is as follows: when the filtering mechanism 2 needs to be installed in the heat preservation pipe body 1, the filtering mechanism 2 is placed at the liquid inlet 11 and pushes the filtering mechanism 2 to move towards the interior of the heat preservation pipe body 1, and the spring 42 can be compressed when the filtering mechanism 2 moves towards the interior of the heat preservation pipe body 1; when one end of the pipe body 21 far away from the primary filter screen 22 is located on one side of the groove 12 close to the anti-dropping block 41, the handle 33 is pushed towards the direction close to the inside of the thermal insulation pipe body 1, so that the pin body 31 protrudes out of the groove 12. At this point, the tube 21 is released and the spring 42 returns to its original shape to urge the tube 21 against the side of the pin 31 adjacent to the primary screen 22.

When impurities are fully accumulated in the dirt storage pipe 25 and the filtering mechanism 2 needs to be taken out and cleaned, the handle 33 is pulled in the direction away from the interior of the heat preservation pipe body 1, so that one side surface of the pin body 31 connected with the short rod 32 is abutted against the bottom wall of the groove 12, and the whole pin body 31 is positioned in the groove 12; then holding the pull ring 5, pulling the filtering mechanism 2 towards the direction close to the liquid inlet 11, and moving the pipe body 21 towards the direction close to the liquid inlet 11 until the pipe body 21 is separated from the heat preservation pipe body 1; and finally, cleaning the sewage storage pipe 25.
