A plurality of atomizing nozzles 23 are fixedly installed in the annular mounting groove 22. The tops of the plurality of atomizing nozzles 23 are lower than the surface of the annular mounting groove 22. The anti-corrosion rubber layer 15 can prevent corrosion inside the two tube bodies. The heat generating mechanism can generate heat flow and introduce it into the connecting plate 20 through the plurality of second connecting pipes 16 and blow it out from the plurality of ventilation grooves 17 to the surface of the tube body for antifreeze. After the sliding ring 19 is connected to the external antioxidant, the mist antioxidant can be sprayed from the plurality of atomizing nozzles 23 to the surface of the tube body. At the same time, the sliding ring 19 can be controlled to slide horizontally along the tube body, so as to evenly spray the antioxidant on the tube body.

[0023] Secondly, a box body 12 is fixedly mounted on the connecting block 3, a two-way pump 13 is fixedly mounted on the box body 12, and the output ends on both sides of the two-way pump 13 are fixedly connected to the first connecting pipe 14, one end of the first connecting pipe 14 is fixedly connected to the sliding collar 19 and is connected to a plurality of atomizing nozzles 23.
