Several sets of outwardly extending heat dissipation fins 5 are fixed on the outer wall of the central pipe 4. A spiral pipe 6 is installed inside the tank body 1. The spiral pipe 6 is located around the central pipe 4 and the heat dissipation fins 5. The upper end of the spiral pipe 6 is connected to a first air inlet pipe 7, and the lower end is connected to a first air outlet pipe 8. The upper part of the central pipe 4 is rotatably connected to the tank body 1. A rotary joint is provided at the top of the tank body 1. The upper end of the central pipe 4 passes through the tank body 1 and is rotatably connected to the rotary joint. A second air inlet pipe 9 communicating with the central pipe 4 is connected to the rotary joint. Specifically, the rotary joint includes a positioning rod 14 and a connector 15 fixed to the positioning rod. The lower end of the positioning rod 14 is connected to the top of the tank body 1. The connector 15 has an annular groove 16. The upper end of the central tube 4 is connected to a slip ring 17, which is slidably disposed in the annular groove 16. The second air inlet pipe 9 is welded to the connector 15 and communicates with the central tube 4. A first sealing ring 18 is provided at the contact point between the connector 15 and the central tube 4. The lower end of the central tube 4 extends out from the bottom of the tank body 1 and is connected to a second air outlet pipe 10. The central tube 4 rotates in the annular groove 16 via the slip ring 17. Steam enters through the second air inlet pipe 9 and then enters the central tube 4, before being discharged through the second air outlet pipe 10. The first sealing ring 18 prevents steam leakage from the connection between the central tube and the connector.

[0026] In this embodiment, the bottom of the tank 1 is provided with a drive mechanism for rotating the central tube 4. The drive mechanism includes a motor 11 mounted on the tank, a transmission shaft connected to the motor via a coupling, a main gear 12 connected to the transmission shaft, and a secondary gear 13 connected to the second vent pipe. The main gear 12 and the secondary gear 13 mesh. Controlling the motor 11 to work drives the transmission shaft to rotate. Through the cooperation of the main gear 12 and the secondary gear 13, the second vent pipe 10 is driven to rotate. The second vent pipe 10 drives the central tube 4 to rotate, thereby driving the heat dissipation fins 5 to rotate. The heat dissipation fins 5 agitate the liquid in the tank 1, making the liquid heated evenly and improving the heating efficiency.

[0027] In this embodiment, a second sealing ring 19 is provided at the contact point between the tank body 1 and the upper end of the central tube 4; a third sealing ring 20 is provided at the contact point between the tank body 1 and the lower end of the central tube 4.

[0029] The working principle of this embodiment is as follows:

[0030] The tank 1 contains a liquid to be heated. Steam is sent into the spiral tube 6 through the first air inlet pipe 7 and into the central tube 4 through the second air inlet pipe 9. The spiral tube 6 heats the outer periphery of the liquid, while the central tube 4 heats the center of the liquid. In addition, the heat dissipation fins 5 on the central tube 4 can further diffuse the heat into the liquid. At the same time, the central tube 4 is rotated by the drive mechanism, and the liquid is stirred by the heat dissipation fins 5, so that the liquid is heated evenly, thereby greatly improving the heating efficiency.
