[0022] In this implementation:

[0023] Furthermore, a sliding assembly 16 is installed on the top of the base plate 25, and a guide slider 15 is slidably installed on the top of the sliding assembly 16. The end of the guide slider 15 away from the sliding assembly 16 is connected to the threaded tube 14. The threaded tube 14 is limited by the guide slider 15 to prevent the threaded tube 14 from rotating with the threaded rod 17.

[0024] Furthermore, a steel pipe feed port 4 is provided at the top of the drying box 24 near one end of the bottom plate 25, and a steel pipe discharge port 11 is provided at the top of the drying box 24 away from the steel pipe feed port 4.

[0032] At this time, the threaded tube 14 drives the guide slider 15 to slide along a straight line on the sliding assembly 16, and the threaded tube 14 drives the loading push plate 2 to move together through the L-shaped rod 1, and the loading push plate 2 can push the steel pipe to move, so that the steel pipe passes through the steel pipe feed port 4 and enters the drying box 24;

[0033] After the steel pipe moves into the drying box 24, it moves between the two groups of turning rollers 6, and the bottom of the steel pipe is supported by the two groups of turning rollers 6. The staff can start the vacuum pump 12 and the electric heating wire 20 through the control panel 5. The vacuum pump 12 draws gas into the heating tube 21, and the gas is heated by the electric heating wire 20. The heated hot gas enters the drying tube 19 through the heating tube 21, and the hot gas is evenly blown to different positions in the drying box 24 through the nozzle 18, so that the steel pipe can be heated and dried;

[0034] At the same time, the staff can start the two sets of first servo motors 9 through the control panel 5, so that the two sets of first servo motors 9 drive the turning rollers 6 to rotate clockwise through the rotating shaft 7, so that the rubber ring 8 can rub against the steel pipe and drive the steel pipe to rotate, and the steel pipe can be turned over, so that the hot air can be evenly blown to different positions of the steel pipe, so that the steel pipe can be dried evenly;

[0035] After drying, the staff can start the second servo motor 13 through the control panel 5, so that the second servo motor 13 drives the threaded rod 17 to rotate clockwise, so that the loading push plate 2 can push the steel pipe to continue to move, so that one end of the steel pipe can pass through the steel pipe discharge port 11 and be pushed out from the inside of the drying box 24, thereby facilitating the discharge of the dried steel pipe.
