[0015] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0016] like Figures 1 to 6 As shown, this utility model provides a drying device for the production of sodium iron phosphate cathode material, including a drying chamber 11, a heat insulation layer 12 inside the drying chamber 11, an anti-corrosion layer 13 inside the heat insulation layer 12, a partition 14 on the anti-corrosion layer 13, a sliding platform 15 on the partition 14, multiple sets of support columns 16 on the sliding platform 15, a fixed cover frame 17 between the multiple sets of support columns 16, multiple sets of bearing strips 18 between two sets of support columns 16, each set of bearing strips 18 is provided with a limiting plate 19, each set of limiting plate 19 is provided with multiple sets of pulley columns 21, multiple sets of rolling columns 22 are provided between the multiple sets of support columns 16, the two ends of the multiple sets of rolling columns 22 are respectively sleeved on the multiple sets of pulley columns 21, each set of rolling columns 22 is provided with a drying box 23, and a controller 24 is provided on one side of the drying chamber 11.

[0017] Specifically, the drying chamber 11, as the main frame of the entire device, provides a closed space for the drying process of the sodium iron phosphate cathode material; the heat insulation layer 12 reduces heat loss inside the drying chamber 11, maintains a stable internal temperature, improves drying efficiency, and reduces energy consumption; the anti-corrosion layer 13 resists the erosion of the interior of the chamber by the sodium iron phosphate material or corrosive substances generated during the drying process, extending the service life of the device; the partition 14 provides an installation base for the sliding platform 15, which can slide along the partition 14, facilitating the removal of the drying box 23 from the chamber for material handling operations, thus improving operational convenience; the support column 16 provides support for components such as the long strip 18 and the rolling column 22. The fixed cover frame 17 enhances the connection stability between the support columns 16 and prevents structural deformation. The bearing strip 18 cooperates with the limiting plate 19 to provide an installation position for the pulley column 21 and prevent the pulley column 21 from shifting. The pulley column 21 is sleeved with the rolling column 22, allowing the rolling column 22 to rotate. When the drying box 23 is placed on the rolling column 22, it can be pushed and pulled by the rotation of the rolling column 22, which facilitates quick loading and unloading. The drying box 23 is used to hold the sodium iron phosphate cathode material to be dried, realizing centralized drying treatment of the material. The controller 24 serves as the core control unit, coordinating the operation of various components of the device. The controller 24 can be an XC3-32T-E controller.

[0018] Multiple sets of support columns 16 are provided with anti-detachment railings 25 on one side, multiple sets of drying boxes 23 are detachably connected to multiple sets of pulley columns 21, multiple sets of limiting holes are opened on one side of multiple sets of drying boxes 23, and multiple sets of foot pads are provided at the bottom of the drying box 11.

[0019] Specifically, the anti-detachment barrier 25 is located on one side of the support column 16, which can prevent the drying box 23 from slipping off the edge of the rolling column 22 during the pushing and pulling process, thus improving operational safety; the detachable connection between the drying box 23 and the pulley column 21 makes it easy to remove the drying box 23 for cleaning or replacement, enhancing the convenience of the device; the limiting hole provides a connection point for fixing the drying box 23 later, ensuring the stability of the drying box 23 during the drying process; the foot column supports the bottom of the drying box 11, keeping the device at a certain distance from the ground, preventing ground moisture from directly corroding the box, while also facilitating bottom ventilation and stable placement of the device.

[0020] Multiple sets of guide strips 26 are provided between the two sets of support columns 16. Each set of guide strips 26 is equipped with a limiting pin 27. One end of each set of limiting pins 27 passes through the guide strips 26 and is inserted into the limiting hole.

[0021] Specifically, the guide bar 26 provides installation and movement guidance for the limiting pin 27, ensuring that the limiting pin 27 can be aligned with the limiting hole of the drying box 23; after the limiting pin 27 passes through the guide bar 26 and is inserted into the limiting hole, the drying box 23 can be fixed on the rolling column 22 to prevent the drying box 23 from shifting due to the vibration of the box during the drying process, and to ensure that the material is heated evenly.

[0022] Both the partition 14 and the sliding platform 15 have through holes on one side. The sliding platform 15 and the partition 14 are slidably connected. Each of the through holes is equipped with a limit pin. The partition 14 has a door panel 28 on one side. The door panel 28 is rotatably connected to the drying oven 11.

[0023] Specifically, the sliding connection between the partition 14 and the sliding platform 15 enables the sliding platform 15 to be pulled out, facilitating material loading and unloading. When the sliding platform 15 is pushed into the appropriate position inside the drying chamber 11, the perforations are aligned, and the limit pin is inserted to fix the sliding platform 15, preventing it from accidentally sliding out during drying. The door panel 28 opens and closes the drying chamber 11 by rotating. When closed, it forms a closed space, reducing heat loss and ensuring a stable drying environment. When open, it facilitates the operation of the sliding platform 15 and the drying box 23.

[0024] like Figure 2 , Figure 7 As shown: A temperature controller 29 is provided on one side of the drying oven 11. A heating tube is installed inside the drying oven 11. The heating tube is located on both sides of the partition 14. The temperature controller 29 is electrically connected to the controller 24.

[0025] Specifically, heating elements are installed on both sides of the partition 14 to uniformly heat the space inside the drying chamber 11, providing the heat required for drying the sodium iron phosphate cathode material. The temperature controller 29 monitors the temperature inside the chamber and feeds the data back to the controller 24. The controller 24 adjusts the working state of the heating elements according to the preset temperature command to control the temperature inside the chamber and ensure that the drying effect meets the process requirements. A filter box 31 is installed inside the drying chamber 11. The bottom of the filter box 31 has multiple sets of air suction holes. A filter plate 32 is installed inside the filter box 31. Multiple sets of suction fans 33 are installed inside the filter box 31, and the suction fans 33 are electrically connected to the controller 24.

[0026] A purification material storage box 34 is provided between multiple sets of suction fans 33 and filter plates 32. A loading frame 35 is provided on the purification material storage box 34. Filter holes are opened on both the purification material storage box 34 and the cover plate 36.

[0027] Specifically, when the suction fan 33 is working, it draws air into the drying chamber 11 through the suction hole at the bottom of the filter box 31, accelerating the air circulation inside the chamber, making the heat distribution more even, and at the same time removing the water vapor evaporated from the material, thus improving the drying efficiency; the filter plate 32 can filter impurities in the air to prevent impurities from contaminating the sodium iron phosphate material; the desiccant or purification material (such as activated carbon) can be placed in the purification material storage box 34 through the loading frame 35. After passing through the filter plate 32, the air passes through the filter hole of the purification material storage box 34, further adsorbing water vapor or harmful components, ensuring a clean drying environment; the cover plate 36 seals and protects the purification material storage box 34, while the filter hole ensures smooth airflow. The suction fan 33 is controlled by the controller 24, and the wind speed can be adjusted to meet the needs of different drying stages.

[0028] The specific usage and function of this embodiment are as follows: In use, first open the drying chamber 11 by rotating the door panel 28, then pull out the limiting pins on the partition 14 and the sliding platform 15, and pull the sliding platform 15 outward along the partition 14. Next, remove the limiting pin 27 on the guide bar 26, push the drying box 23 to slide along the rolling column 22 and the pulley column 21, remove the drying box 23 from between the support columns 16, and then put the sodium iron phosphate cathode material to be dried into the drying box 23.

[0029] Next, place the drying box 23 containing the material back onto the rolling column 22, push the drying box 23 to the appropriate position, align the limiting hole on one side of the drying box 23 with the limiting pin 27 on the guide strip 26, insert the limiting pin 27 to fix the drying box 23 and prevent it from shifting in subsequent operations.

[0030] After loading and securing all drying boxes 23, push the sliding platform 15 back into the drying chamber 11. When the partition 14 aligns with the perforations on the sliding platform 15, insert the limiting pin to secure the sliding platform 15, and finally close the door panel 28. Set the required drying temperature parameters via the controller 24, which then transmits the command to the temperature controller 29. The temperature controller 29 controls the heating elements on both sides of the partition 14 to begin heating the interior of the drying chamber 11. During heating, the temperature controller 29 monitors the temperature inside the chamber and sends feedback to the controller 24, ensuring the temperature remains stable within the set range. At the same time, the controller 24 starts the suction fan 33 in the filter box 31. The suction fan 33 draws air into the drying chamber 11 through the suction hole at the bottom of the filter box 31. The air first passes through the filter plate 32 to filter out impurities, and then passes through the purified material storage box 34 (the material loading frame 35 can hold desiccant or activated carbon and other purification materials). It further adsorbs water vapor and harmful components through the filter holes. The purified air circulates in the drying chamber 11, which accelerates the evaporation of moisture in the material and improves the drying efficiency.

[0031] After drying is complete, controller 24 shuts off the heating element and suction fan 33. Once the temperature inside the drying chamber 11 drops to a suitable range, open door panel 28, pull out limit pin, pull out sliding platform 15, remove limit post 27, and remove drying box 23 to complete the entire drying process. Its main functions are as follows: the heat insulation layer 12 and anti-corrosion layer 13 reduce heat loss and prevent corrosion of the chamber, extending the service life of the device; the cooperation between sliding platform 15 and rolling column 22 makes it easier to place and remove drying box 23, improving operational efficiency; the limit post 27, limit pin, and other components ensure the stability of the positions of each component during drying, guaranteeing a stable drying environment; the coordinated work of heating element and temperature controller 29 achieves temperature control, meeting the drying process requirements of sodium iron phosphate cathode material; the purification circulation system composed of suction fan 33, filter plate 32, and purified material storage box 34 accelerates drying while ensuring material purity; the anti-detachment railing 25 and foot posts respectively improve operational safety and device placement stability.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
