[0038] The working principle and usage process of the present invention are as follows: When in use, the wind turbine flange to be processed (hereinafter referred to as the workpiece) is placed on the metal mesh plate 333, and the second driving member 330 is controlled to extend to move the metal mesh plate 333 downward, and vice versa, the metal mesh plate 333 is moved upward, thereby facilitating the user to adjust the distance between the workpiece and the thermal spray gun 344. When the position of the thermal spray gun 344 needs to be adjusted, the fourth driving member 341 is controlled to extend to cause the transmission block 350 to cooperate with the transmission iron pipe 346 to drive the thermal spray gun 344 to move away from the liquid storage metal pipe 345, and vice versa, the thermal spray gun 344 is moved toward the liquid storage metal pipe 345, thereby facilitating the user to quickly adjust the positions of multiple thermal spray guns 344.

[0039] When it is necessary to locally heat the workpiece, the workpiece is heated by the thermal spray gun 344. If the workpiece is driven to rotate by the power output member 336 at this time, annular heating of the workpiece can be achieved. If it is necessary to heat the workpiece in all directions, the third driving member 331 is controlled to contract so that the workpiece moves down into the mounting metal tube 32, and then the first driving member 8 is controlled to extend so that the blocking metal plate 5 is inserted into the top of the mounting metal tube 32, thereby creating a small-scale enclosed space for subsequent heating of the workpiece to increase the heating speed and reduce the heating energy consumption, and energy is stored in the enclosed space so that energy loss can be significantly reduced when multiple workpieces are processed continuously. Then, the workpiece is heated by the thermal spray gun 344. During the heating process, the workpiece is driven to rotate, and the reciprocating movement of the thermal spray gun 344 is coordinated to achieve all-round rapid heating of the workpiece, significantly increasing the heating speed of the workpiece and significantly reducing the energy consumption of the device.

[0040] Therefore, through the mutual cooperation of multiple structures, the user can use the heat treatment device to quickly heat the flange in all directions under the premise of energy saving and environmental protection, effectively reducing the energy consumption of the heat treatment device. Secondly, the present invention can locally heat the flange according to actual processing needs, making the application range of the heat treatment device wider. In addition, the present invention can be applied to flanges of different models, further improving the applicability of the heat treatment device, and the present invention has a simple structure and is easy to use.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
