Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.
[0025] Example 1: Please refer to Figures 1 to 5This utility model provides a technical solution: a drying device for preparing battery-grade aluminum chloride, the drying device for preparing battery-grade aluminum chloride includes: a drying cylinder 1, a stirring rake tooth 2 is provided inside the drying cylinder 1, an electric heating frame 3 is wrapped around the outer wall of the drying cylinder 1, and a heat insulation sleeve 4 is wrapped around the outside of the electric heating frame 3.
[0026] A support base plate 5 is provided, a vacuum pump 6 is provided on the surface of the support base plate 5, the vacuum pump 6 is connected to the inside of the drying cylinder 1, and a control box 7 is provided on the surface of the support base plate 5.
[0027] When using, aluminum chloride can be placed in the drying cylinder 1, and the vacuum pump 6 can be started to evacuate the internal environment of the drying cylinder 1. Then, the temperature of the electric heating frame 3 can be controlled by the control box 7 to evaporate the moisture. While drying, the rotating stirring rake 2 can prevent local heating and clumping. The control box 7 can also control the temperature of the electric heating frame 3 to prevent changes or decomposition of the material properties, thus avoiding the problem of poor quality of dried aluminum chloride.
[0028] Example 2: Based on Example 1, in order to make the material heat more evenly during drying, a groove is provided at one end of the rotating shaft 10, and the output end of the reducer 13 is inserted into the groove. Several linearly equidistant stirring rake teeth 2 are fixedly installed on the surface of the rotating shaft 10, and the stirring rake teeth 2 are staggered.
[0029] The drying cylinder 1 has holes at both ends, and sealing blocks 8 are inserted into the holes. The sealing blocks 8 are fixedly installed at both ends of the drying cylinder 1. A fixed bearing 9 is installed inside the sealing block 8. A rotating shaft 10 is fixedly connected to the inner ring surface of the fixed bearing 9. A hole is opened at the top of the drying cylinder 1, and a feed pipe 11 is fixedly installed inside the hole. A sealing cover 12 is screwed into the feed pipe 11. A hole is opened at the bottom of the drying cylinder 1, and a discharge pipe 19 is fixedly installed inside the hole. A sealing cover 12 is screwed into the discharge pipe 19.
[0030] During drying, the rotating shaft 10 drives the stirring rake teeth 2 to rotate. The stirring rake teeth 2 are installed in a staggered manner on the surface of the rotating shaft 10. The stirring rake teeth 2 can stir the material in the drying cylinder 1, so that the material forms a continuous circulation state in the cylinder, making it heat more evenly and avoiding the problem of clumping caused by local heating. It can also prevent the material from sticking to the inner wall of the drying cylinder 1, thus making the material heat more evenly as a whole.
[0031] Example 3: Based on Example 2, in order to prevent aluminum chloride from decomposing due to excessively high temperature during material drying, a vacuum pump 6 is installed and connected to the inside of the drying cylinder 1 through a vacuum pipe 14. A transfer box 15 is installed near the end of the vacuum pipe 14 near the drying cylinder 1. A filter screen 16 is fixedly installed on the inner wall of the pipe at the connection between the transfer box 15 and the vacuum pipe 14.
[0032] To prevent aluminum chloride from decomposing due to excessively high drying temperature, a vacuum pump 6 is used to evacuate the inside of the drying cylinder 1 during drying. This lowers the boiling point of water in the material, allowing it to evaporate at a lower temperature. The vacuum pump 6 can also extract the evaporated water vapor from the drying cylinder 1 through the vacuum pipe 14, and the filter screen 16 inside the vacuum pipe 14 can effectively intercept solid particles from entering the vacuum pump 6.
[0033] The electric heating frame 3 has its inner wall attached to the outer wall of the drying cylinder 1. The electric heating frame 3 is electrically connected to the control box 7. The control box 7 has control keys on its surface. The support base plate 5 has a support block 17 on its surface. A motor 18 is fixedly installed at one end of the support block 17. A reducer 13 is installed at one end of the motor 18.
[0034] During drying, the operator can control the drying temperature of the electric heating frame 3 through the control box 7, thereby avoiding the problem of material decomposition due to excessively high drying temperature and insufficient drying due to excessively low drying temperature.
[0035] Working principle: In actual use, aluminum chloride can be placed in the drying cylinder 1, and the vacuum pump 6 is started to evacuate the internal environment of the drying cylinder 1. Then, the temperature of the electric heating frame 3 is controlled by the control box 7 to evaporate the moisture. While drying, the rotating stirring rake 2 is rotated to avoid local heating and clumping. The control box 7 can also control the temperature of the electric heating frame 3 to prevent changes in the material properties or decomposition. This avoids the problem of poor quality of dried aluminum chloride.
[0036] 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.
