[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7This utility model provides a technical solution: a molten salt energy storage drying device, including a base 1, a heating tank 11, and a drying chamber 12. The heating tank 11 has a feeding hopper 13 at its top and a turning component on its surface. A drying component is provided between the drying chamber 12 and the heating tank 11. The turning component includes a first rotating shaft 21 connected to the top of the heating tank 11, a protective box 22 fixedly connected to the bottom of the first rotating shaft 21, a second rotating shaft 23 fixedly connected to the bottom of the protective box 22, a first turning blade 24 fixedly connected to the outer side of the second rotating shaft 23, a driven bevel gear 25 fixedly connected to the outer side of the first rotating shaft 21, a driving bevel gear 26 connected to the driven bevel gear 25, a drive shaft 27 fixedly connected to the driving bevel gear 26, and a component fixed to one end of the drive shaft 27. The system includes a first motor 28 and auxiliary components for further improving heating efficiency. A first rotating shaft 21 is rotatably connected to the heating tank 11. A driving bevel gear 26 meshes with a driven bevel gear 25. The first motor 28 drives the driving bevel gear 26 to rotate, which in turn causes the driven bevel gear 25 and the first rotating shaft 21 to rotate. This, in turn, drives the second rotating shaft 23 and the first agitator 24 to rotate, agitating and heating the molten salt in the heating tank 11 to ensure full contact with the heating wire 32, thus improving heating efficiency. A support plate 71 is provided on the outer side of the drive shaft 27, rotatably connected to it. The bottom of the support plate 71 is fixedly connected to the top of the heating tank 11, providing support for the drive shaft 27 and preventing it from swinging, ensuring the main... To ensure the meshing stability of the moving bevel gear 26 and the driven bevel gear 25, auxiliary components include a third rotating shaft 41 connected to one side of the protective box 22, a fourth rotating shaft 42 connected to the other side of the protective box 22, a second tumbling blade 43 fixedly connected to the outer sides of the third rotating shaft 41 and the fourth rotating shaft 42 respectively, a second motor 44 fixedly connected to the top of the third rotating shaft 41, a driving wheel 45 fixedly connected to the outer side of the third rotating shaft 41, a driven wheel 46 fixedly connected to the outer side of the fourth rotating shaft 42, and a belt 47 disposed between the driving wheel 45 and the driven wheel 46. The driving wheel 45 and the driven wheel 46 are connected by a drive belt 47. Both the third rotating shaft 41 and the fourth rotating shaft 42 are rotatably connected to the protective box 22. The second motor 44 can drive the third rotating shaft 41 and the driving wheel 45 to rotate. The drive belt 47 can drive the driven wheel 46 and the fourth rotating shaft 42 to rotate, which in turn causes the second agitator 43 to rotate. This allows the second agitator 43 to rotate simultaneously with the rotation of the protective box 22, thereby improving the agitation efficiency of the molten salt and its heating efficiency. The top of the feeding hopper 13 is equipped with a fixed cover 61, with a groove 62 on its top. A sliding rod 63 is slidably connected within the groove 62. A first spring 64 is fixedly connected to the bottom of the sliding rod 63, and a first inclined block 65 is fixedly connected to the top of the sliding rod 63. Second inclined blocks 66 are respectively located on both sides of the first inclined block 65, and a locking rod 67 is fixedly connected to one side of each second inclined block 66. Baffles 68 are fixedly connected to both sides of the top of the fixed cover 61, and a second spring 69 is sleeved on the outside of the locking rod 67.The feeding hopper 13 has slots 70 on both sides, and a locking rod 67 is inserted into the slots 70. The locking rod 67 passes through the baffle 68 and is slidably connected to the baffle 68. The two ends of the second spring 69 are fixedly connected to the baffle 68 and the second inclined block 66, respectively. By moving the first inclined block 65 vertically, the two second inclined blocks 66 can be squeezed to move horizontally, thereby driving the locking rod 67 to move. This facilitates the fixing or disassembly of the fixed cover 61. The first spring 64 and the second spring 69 can respectively reset the first inclined block 65 and the locking rod 67. A handle 651 is fixedly connected to the top of the first inclined block 65. The handle 651 is T-shaped and can be used to easily move the first inclined block 65 vertically, thereby allowing the locking rod 67 to move and facilitating the fixing or disassembly of the fixed cover 61.

[0026] Please see Figure 1 , Figure 2 as well as Figure 3 The drying components include a blower 31 fixedly connected to one side of the top of the base 1, a heating wire 32 fixedly connected to the inner wall of the heating tank 11, and a serpentine tube 33 fixedly connected to the output end of the blower 31. The serpentine tube 33 is located inside the heating tank 11 and is connected to the drying chamber 12. The left side of the serpentine tube 33 is fixedly connected to the blower 31, and the right side of the serpentine tube 33 is fixedly connected to the drying chamber 12. The serpentine tube 33 can increase the contact time between the outside air and the molten salt, allowing the heat to be fully absorbed by the air. When the blower 31 is started, air is blown into the serpentine tube 33. Through heat exchange with the molten salt, hot air can be inserted into the drying chamber 12, thereby quickly drying the items inside the drying chamber 12. A door 51 is hinged on one side of the drying chamber 12, and a drive handle 52 is fixedly connected to one side of the door 51. The drive handle 52 can be used to easily open or close the door 51, making it easy to take out items and perform drying operations.

[0027] Working principle: During operation, molten salt is added to the heating tank 11 through the feeding hopper 13. Pulling the handle 651 moves the first inclined block 65 upward, which in turn moves the two sliding rods 63 upward. The upward movement of the sliding rods 63 causes the first spring 64 to deform, and simultaneously, the first inclined block 65 presses the two second inclined blocks 66 to move. The movement of the second inclined blocks 66 moves the locking rod 67, and at the same time, the second spring 69 deforms. Then, the fixing cover 61 is placed on top of the feeding hopper 13, and the handle 651 is released. The first spring 64 and the second spring 69 return to their original positions, causing the first inclined blocks 65 and the second inclined blocks 66 to return to their original positions. This allows the locking rod 67 to engage in the locking slot 70, fixing the fixing cover 61 to the feeding hopper 13. Then, the heating wire 32 is energized, and the first motor 28 and the second motor 44 are started. The first motor 28 drives the drive shaft 27 and the active bevel gear 26 to rotate. The rotation of the driving bevel gear 26 drives the driven bevel gear 25 and the protective box 22 to rotate, which in turn drives the second rotating shaft 23 and the first tumbling blade 24 to rotate. The second motor 44 drives the third rotating shaft 41 and the driving wheel 45 to rotate. The driving wheel 45 drives the driven wheel 46 and the fourth rotating shaft 42 to rotate via the belt 47, which in turn drives the second tumbling blade 43 to rotate. The first tumbling blade 24 and the second tumbling blade 43 can cause the molten salt to tumble, so that it can be heated quickly and then enter the heat preservation state. The blower 31 is started, and the blower 31 blows air into the serpentine tube 33. Through heat exchange with the molten salt, the hot air can be inserted into the drying box 12, so that the items in the drying box 12 can be dried quickly. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
