[0002] A steam generator is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam. After searching, it was found that the Chinese utility model patent with the authorization publication number CN214468520U discloses a steam generator.

A cylindrical cavity 405 with a bottom opening is provided on one side of the box body 404. A fan 406 is provided in the box body 404. A hose 407 is connected to the air outlet pipe of the fan 406. A central tube 408 is fixed to the box body 404. The central tube 408 extends into the cylindrical cavity. A plurality of first air holes are opened on the central tube 408.

It should be noted that multiple rows of screw holes can be arranged on both sides of the chassis. When installing the support plate, the support plate can be installed on the appropriate screw holes according to the position of the pneumatic chuck, so that the cylindrical cavity can be located above the pneumatic chuck. Furthermore, in order to enable the pneumatic chuck to accurately reach the bottom of the cylindrical cavity, manual observation may be adopted, or a position sensor may be provided on the pneumatic chuck or the box.

[0029] In this embodiment, a controller is further provided in the chassis, and the first motor 6 and the second motor 11 are both electrically connected to the controller. A control program is preset in the controller for controlling the first motor and the second motor to work respectively.

[0030] The working principle of this embodiment is:

[0031] The processed workpiece is placed on the pneumatic chuck 3 and fixed by the pneumatic chuck 3. The driving mechanism drives the turntable 2 to rotate. After the turntable 2 reaches the bottom of the cylindrical cavity 405, the lifting mechanism controls the box 404 to descend, so that the cylindrical cavity 405 is sleeved on the periphery of the workpiece, and the center tube 408 enters the workpiece, and the spiral tube 410 is located outside the workpiece. Then the fan 406 starts to work, and the wind blows from the first wind hole to the inside of the workpiece, and the wind blows from the second wind hole to the outside of the workpiece, so that the workpiece is cooled quickly.

When drying the inner wall, if the outer shell 13 is not welded with the pipe 14, after the spiral tube 410 is sleeved on the outer shell 13, the outer shell 13 can be located at the center of the spiral tube 410, so that the second air hole blows air evenly to the outer shell. If the outer shell 13 is welded with the pipe 14, it is necessary to slide the spiral tube 410 to adjust the position of the spiral tube 410. After the adjustment is completed, tighten the fastening bolts 414 to fix the positioning plate 413 on the box body 404, so that the entire outer shell 13 and the pipe 14 can enter the spiral tube 410, so that the outer shell and the pipe can be dried at the same time.
