[0020] Working principle: Steam enters from the air inlet 3, is transmitted to the pipeline 11 through the connecting box 10, then enters the connecting cylinder 7, and is output from the air outlet 6. The fluid is transmitted in the box body 2 through the fluid valve 1 4 and the fluid valve 2 5 to perform heat exchange treatment with the steam; when the steam is output from the air outlet 6, the connecting gear ring 34 is driven to rotate by the control motor 28, and the fixed particle impurities in the steam can be captured by the filter layer 36 to achieve filtration; when the steam enters each pipeline 11 from the connecting box 10, the steam flows through the holes on the porous sliding disk 49. The steam flows at the holes and the flow rate changes, which can enhance turbulence and improve heat exchange efficiency.

[0021] When the inside and outside of the pipe 11 are subsequently maintained, the indexing disk 15 is driven to rotate by the motor 13, so that the pushing electric cylinder 22 is located at the target position, and the pushing electric cylinder 22 pushes the blocking shaft 31, so that the connecting hole 33 is connected with the end of the pipe 11, and the moving rack shaft 21 is driven to move by the moving motor 20, and the moving rack shaft 21 passes through the connecting hole 33 and extends to the inside of the pipe 11. When the clamping cylinder 23 moves to the end face of the porous sliding disk 49, the electromagnetic sliding shaft 26 is connected to the hole position on the matching ring 4901. Cooperate, and the electromagnetic sliding push rod 27 pushes one end of the locking rod 52, so that the locking rod 52 releases the fixation of the porous sliding disk 49, and the clamping cylinder 23 can drive the porous sliding disk 49 to move inside the pipe 11 to push the impurities attached to the inside of the pipe 11. The impurities are pushed into the inside of the connecting cylinder 7, and the orientation is changed by the indexing disk 15 to move the inside of each pipe 11. By moving the rack shaft 21, the porous sliding disk 49 can be transferred back to the end of the pipe 11 and fixed by the locking rod 52.

[0022] Furthermore, the moving rack shaft 16 is driven to move by the moving motor 18. When the clamping cylinder 24 moves to the end face of the moving cylinder 38, the electromagnetic sliding shaft 25 cooperates with the hole on the matching part 39 to fix the moving cylinder 38. At the same time, the electromagnetic sliding shaft 3 51 releases the cooperation with the hole on the matching part 2 54, and the moving rack shaft 16 drives the moving cylinder 38 to move, and the rolling ring 46 moves on the outside of the pipe 11.

After the attachments are removed, the moving cylinder 38 can be transferred to the end face of the connecting box 10 for fixation.
