[0022] In this embodiment, when the device is used, the feed pipe 228 is connected to the external molten salt feed mechanism, the steam inlet pipe 12 sends the steam generated by thermal power to the inside of the heating body 1, and then the feed mixing mechanism 2 is turned on. The start of the feed mixing mechanism 2 is to turn on the servo motor 211. The start of the servo motor 211 makes the mixing component 21, the feed component 22 and the thermal cycle component 23. The mixing component 21 is driven by the servo motor 211 to rotate the rotating shaft 212. The rotation of the rotating shaft 212 is driven by the driving gear 213 and the four follower gears. The meshing of the wheel 215 drives the driven shaft 214 to rotate, so that the stirring blade 216 on the driven shaft 214 stirs the molten salt to increase the heating surface of the molten salt, and the feeding component 22 is the rotating shaft 212 that drives the worm 220 to rotate, and the worm 220 drives the two worm wheels 222 to rotate by meshing with the two worm wheels 222.

When the active semi-bevel gear 223 rotates to the tooth-missing position, the torsion spring 226 returns the rotating shaft 224 to its original position, so that the follower semi-bevel gear 225 is reset to prepare for the next meshing transmission of the active semi-bevel gear 223. During the rotation of the follower semi-bevel gear 225, the rotating shaft 224 is driven to rotate. The rotation of the rotating shaft 224 causes the baffle 227 to rotate, so that the feed pipe 228 is connected to the inner frame 20 to feed the molten salt. The two baffles 227 on the left and right sides are opened cyclically, so that the feeding is more uniform, which improves the molten salt. Mixing efficiency, and the heat circulation component 23 is one of the follower gears 215 that drives the first meshing gear 232 to rotate, the first meshing gear 232 is meshed with the inner ring teeth of the inner and outer ring gears 233, driving the inner and outer ring gears 233 to rotate, and during the rotation of the inner and outer ring gears 233, through the meshing of its outer ring gear with a plurality of second meshing gears 235, driving a plurality of air outlet shafts 234 to rotate, the rotation of the air outlet shaft 234 causes the fan blades 236 to rotate, thereby accelerating the circulation of steam in the heating body 1 and improving the heating efficiency of the molten salt.
[0023] Example 2 like Figure 1 to Figure 8 As shown, the bottom heating assembly 31 includes a heating base 311, which is fixedly connected to the bottom of the heating frame 11, and a circulation guide plate 312 is fixedly connected to the top of the heating base 311, and the circulation guide plate 312 is in contact with the bottom of the inner frame 20.

[0025] like Figure 1 to Figure 8 As shown, a groove is formed on the circular frame 321 , and a plurality of grooves on the circular frame 321 are arranged at intervals on the left and right, and the connecting pipe 324 fits in the groove.
[0026] In this embodiment, during the molten salt heating and stirring process, steam flows from the steam inlet pipe 12 to the heating mechanism 3, and the steam first passes through the bottom heating component 31, and is circulated and transmitted in the circulation guide plate 312 in the bottom heating component 31, thereby increasing the contact area between the bottom of the inner frame 20 and the steam. After the steam is sent out from the bottom heating component 31, the steam enters the side heating component 32. After entering the side heating component 32, the steam is heat-circulated between the heating frame 11 and the inner frame 20 and inside the inner frame 20 by the arrangement of multiple circular frames 321 and grooves and connecting pipes 324 arranged at intervals on the left and right sides. During the steam heat cycle, the moisture in the steam is intercepted by the side circular frame 321, guided by the side guide plate 322 to fall onto the lower water plate 323, and then falls from the lower water plate 323 to the outer edge of the heating base 311, and is sent out by the water outlet pipe 14, thereby improving the thermal conversion efficiency of the steam.
