The pipe interface 2 is installed on both ends of the air exchanger 1, and the replacement device 3 is disposed on the surface of the pipe interface 2.

[0022] The specific settings and functions of the replacement device 3 and the limiting device 4 will be explained in detail below.

[0023] In this embodiment: the replacement device 3 includes a main frame 31, which is fixedly connected to the surface of the pipe interface 2. The inner side of the main frame 31 is provided with an internal groove 33. A movable frame 32 is slidably connected inside the internal groove 33. A filter element 37 is placed inside the movable frame 32. A movable rod 34 is inserted and connected inside the movable frame 32. The movable rod 34 is inserted into the filter element 37. A tension spring 36 is fixedly connected between the movable rod 34 and the movable frame 32.

[0024] Specifically, a guide rod 35 is fixedly connected to one side of the movable frame 32, and the movable insertion rod 34 is slidably connected to the surface of the guide rod 35. The guide rod 35 can cooperate with the movable frame 32 to support the guide rod 35 and guide the movable insertion rod 34 to slide.

[0025] Specifically, the handle of the movable frame 32 is provided with a limiting device 4, which includes a linkage bar 43, and the linkage bar 43 is fixedly connected to the handle of the movable frame 32.

[0026] In this embodiment, the linkage bar 43 can cooperate with the movable frame 32 to achieve the purpose of supporting the linkage bar 43.

[0027] In this embodiment: support blocks 42 are fixedly connected to both ends of the linkage bar 43. The support blocks 42 are slidably connected to the outer side of the main frame 31. The linkage bar 43 can cooperate with the support blocks 42 to achieve the purpose of fixing the support blocks 42.

[0028] Specifically, the support block 42 has a positioning rod 41 connected to its internal thread, and the positioning rod 41 is located on both sides of the movable frame 32.

[0029] In this embodiment, the positioning rod 41 can cooperate with the support block 42 to guide the positioning rod 41 into the positioning hole 44.

[0030] Specifically, positioning holes 44 are provided on both sides of the main frame 31, and the positioning rod 41 is inserted into the positioning hole 44.

[0031] In this embodiment, the positioning hole 44 can cooperate with the main frame 31 to achieve the purpose of storing the positioning rod 41.

[0032] Working principle: By setting up the replacement device 3, when the worker needs to replace the filter element 37, the new filter element 37 is placed in the empty slot of the movable frame 32, the movable insertion rod 34 is released, and the spring 36 is pulled to pull the movable insertion rod 34. Guided by the guide rod 35, the movable insertion rod 34 slides and inserts into the filter element 37. The worker pulls the handle of the movable frame 32, which moves the movable frame 32 to slide in the built-in slot 33 of the main frame 31. The movable frame 32 moves the installed filter element 37 to slide, the old filter element 37 disengages from the pipe interface 2, and the new filter element 37 connects to the pipe interface 2. The movable frame 32 is then restrained, and the worker can remove the old filter element 37. By setting up the replacement device 3, the worker can effectively and conveniently remove the filter element 37. The replacement of filter element 37 avoids inconvenience for workers during the replacement process, thus reducing the difficulty of filter element replacement. Furthermore, by setting a limiting device 4, when workers need to limit the movement of the movable frame 32, they adjust the movable frame 32, which drives the linkage bar 43. The linkage bar 43 drives the support block 42, which in turn drives the positioning rod 41. When the movable frame 32 slides to the designated position, the positioning rod 41 is rotated, extending and inserting into the positioning hole 44. By setting the limiting device 4, the installation and removal of filter element 37 can be effectively facilitated, preventing the movable frame 32 from sliding during installation or removal, thereby improving the convenience of filter element replacement.
