Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-5As shown, the utility model is a production equipment for Prussian blue sodium ion cathode material, including a mounting box 1, a box door 11 rotatably connected to the top rear end of the outer wall of the mounting box 1, and also includes;

[0028] The mounting mechanism 2 includes heaters 21 fixedly connected to the left and right sides of the inside of the mounting box 1. Mounting plates 22 are fixedly connected to the bottom left and right sides of the inner wall of the mounting box 1. A first motor 23 is fitted and fixedly connected to the bottom of the inner wall of the mounting box 1. A connecting rod 231 is fixedly connected to the output end of the first motor 23. The top of the outer wall of the connecting rod 231 is rotatably connected to the center of the inner wall of the mounting plate 22. A second motor 25 is fitted and fixedly connected to the top inner wall of the support shell 24. When the first motor 23 is started, it rotates, driving the connecting rod 231, the support shell 24, and the rotating rod 28 to rotate. The rotating rod 28 drives the second bevel gear 29 to rotate eccentrically with the heat-conducting shell 34 and the cover shell 36. Finally, the second motor 25 is started, driving the central rotating shaft 26 and the central first bevel gear 27 to rotate.

[0029] The top inner wall of the support shell 24 is provided with several rotating shafts 26. There are three rotating shafts 26. The bottom ends of the left and right rotating shafts 26 are connected to the left and right rotating rods on the top of the support shell 24, respectively. The bottom end of the rotating shaft 26 at the center is fixedly connected to the output end of the second motor 25.

Second bevel gears 29 are sleeved and fixedly connected to the top of the outer walls of both rotating rods 28. The first bevel gear 27 at the center drives the left and right first bevel gears 27 to rotate. The left and right first bevel gears 27 respectively drive the left and right second bevel gears 29 to rotate with the rotating rods 28. The second bevel gear 29 drives the mounting shell 31, the heat-conducting shell 34, and the material to rotate around the center. The heat-conducting shell 34 will introduce the heat from the heater 21 into the interior of the heat-conducting shell 34 and rotate in conjunction with its rotation to dry and dehydrate the material. By starting the first motor 23, the connecting rod 231, the heat-conducting shell 34, and the material will rotate centrifugally. Then, by starting the second motor 25, the central rotating shaft 26 will rotate with the heat-conducting shell 34 and the material. In conjunction with the heat from the heater 21, the material will be dried and dehydrated, thereby achieving the dehydration effect. This prevents water from occupying the original Na+ storage sites, affecting the normal transport of Na+, reducing the specific capacity of the material, and thus affecting the overall energy density and power output of the battery.

[0031] The rear end of the first threaded rod 32 passes through the interior of the mounting shell 31 and extends to the outside. The outer walls of the front and rear ends of the first threaded rod 32 are rotatably connected to the front and rear ends of the inner wall of the mounting shell 31. The second threaded rod 311 drives the sleeve 312 to move obliquely downward on the inner wall of the fixed shell 39.

[0032] The front and rear ends of the outer wall of the first threaded rod 32 are fitted with and threaded with a convex shell 33. The outer wall of the convex shell 33 is in contact with the inner wall of the mounting shell 31. A heat-conducting shell 34 is provided on the top of the outer wall of the mounting shell 31. First, open the box door 11, then rotate to open the cover shell 36 and pour the material into the heat-conducting shell 34.

[0033] The top of the outer wall of the heat-conducting shell 34 is provided with a threaded line 341. A cover shell 36 is fitted and threadedly connected to the top of the outer wall of the heat-conducting shell 34. A connecting pipe 37 is connected and fixedly connected to the top of the cover shell 36. Then, the cover shell 36 is rotated to close the heat-conducting shell 34. Then, the box door 11 is closed and the material is stored inside the device.

[0034] A gear 38 is fitted and fixedly connected to the center of the outer wall of the first threaded rod 32. A fixed shell 39 is fixedly connected to the right side of the inner wall of the mounting shell 31. A third motor 310 is fitted and fixedly connected to the right side of the inner wall of the fixed shell 39. When the third motor 310 is started, it drives the second threaded rod 311 to rotate. The second threaded rod 311 drives the sleeve 312 to move obliquely downward on the inner wall of the fixed shell 39. The sleeve 312 drives the toothed plate 313 to slide on the inner wall of the mounting shell 31. The toothed plate 313 drives the gear 38 and the first threaded rod 32 to rotate. The first threaded rod 32 drives the two convex shells 33 to move toward their center, placing the heat-conducting shell 34 above the mounting shell 31. The outer walls of the two convex shells 33 contact the inner walls of the two limiting shells 35, limiting the heat-conducting shell 34 to be installed above the mounting shell 31.

[0035] The output end of the third motor 310 is fixedly connected to the second threaded rod 311. The outer wall of the second threaded rod 311 is fitted with and threadedly connected to the housing 312. The outer wall of the housing 312 contacts the inner wall of the fixed housing 39. The left end of the second threaded rod 311 is fixedly connected to the toothed plate 313. The bottom of the outer wall of the toothed plate 313 is fitted with and slidably connected to the bottom of the inner wall of the mounting housing 31. The outer wall of the toothed plate 313 meshes with the inner wall of the gear 38. By starting the third motor 310, the second threaded rod 311 is driven to rotate. The second threaded rod 311 drives the convex shell 33 to clamp and limit the limiting shell 35 and the heat-conducting shell 34 above the outer wall of the mounting housing 31. This allows for quick installation and removal of the heat-conducting shell 34, facilitating the quick removal and loading of dewatering materials and improving work efficiency.

[0036] A specific application of this embodiment is as follows: When using this device, first open the box door 11, then rotate the cover 36 to pour the material into the heat-conducting shell 34. Next, rotate the cover 36 to close the heat-conducting shell 34, then close the box door 11. Then, start the heater 21 to heat the air inside the installation box 1. Start the first motor 23 again to rotate. The first motor 23 drives the connecting rod 231, the support shell 24, and the rotating rod 28 to rotate. The rotating rod 28 drives the second bevel gear 29 to rotate eccentrically with the heat-conducting shell 34 and the cover 36. Finally, start the second motor 25. The second motor 25 drives the central rotating shaft 26 and the central first bevel gear 27 to rotate. The central first bevel gear 27 drives the left and right first bevel gears 27 to rotate. The left and right first bevel gears 27 respectively drive the left and right first bevel gears 27 to rotate. The second bevel gear 29 rotates with the rotating rod 28. The second bevel gear 29 drives the mounting shell 31, the heat-conducting shell 34, and the material to rotate around the center. The heat-conducting shell 34 will introduce the heat from the heater 21 into the interior of the heat-conducting shell 34 and rotate in conjunction with its rotation to dry and dehydrate the material. By starting the first motor 23, the connecting rod 231, the heat-conducting shell 34, and the material will rotate centrifugally. Then, by starting the second motor 25, the central rotating shaft 26 will rotate with the heat-conducting shell 34 and the material. This, in conjunction with the heat from the heater 21, will dry and dehydrate the material, thus achieving the dehydration effect. This avoids the lack of a corresponding dehydration treatment unit for Prussian blue compounds synthesized from aqueous solutions, which would result in a high moisture content in the produced product, which is not conducive to subsequent drying and pulverizing processes and would also have an adverse effect on the quality and stability of the product.

[0037] When using this device, the third motor 310 is started, which drives the second threaded rod 311 to rotate. The second threaded rod 311 drives the sleeve 312 to move obliquely downward on the inner wall of the fixed shell 39. The sleeve 312 drives the toothed plate 313 to slide on the inner wall of the mounting shell 31. The toothed plate 313 drives the gear 38 to rotate with the first threaded rod 32. The first threaded rod 32 drives the two convex shells 33 to move towards their center, placing the heat-conducting shell 34 above the mounting shell 31. The outer walls of the two convex shells 33 contact the inner walls of the two limiting shells 35, limiting the heat-conducting shell 34 to be mounted above the mounting shell 31. By starting the third motor 310, the second threaded rod 311 is driven to rotate, and the second threaded rod 311 drives the convex shells 33 to clamp and limit the limiting shells 35 and the heat-conducting shell 34 above the outer wall of the mounting shell 31. This allows for quick installation and removal of the heat-conducting shell 34, facilitating the quick removal and loading of dewatering materials and improving work efficiency.
