The damp-proof storage device for titanium dioxide production is used for long-time storage of the produced titanium dioxide. When in use, the flow guide assembly 5 is controlled to move upward by using the first lifting rod 21, the discharge port 7 at the bottom of the storage tank 1 is closed by using the sealing cover, a hole is arranged at the side edge of the storage tank 1, the titanium dioxide is directly put into the inside of the baffle 8 of the storage tank 1 through the hole and is accumulated in the inside of the storage cavity 6, then the hole for feeding is closed, at this moment, the storage can be carried out, the driving mechanism 2 at the top is started regularly during the long-time storage process, the flow guide assembly 5 is controlled to move downward by using the driving mechanism 2, the surface layer titanium dioxide is frictionally crushed by using the flow guide assembly 5, air in the storage cavity 6 is extracted by using the external air blower and other air supply equipment, the air in the storage cavity 6 is replaced by the air in the drying assembly 3 at the side edge after drying, and the dry state of the air in the inside is ensured during the long-time storage process.

[0028] The flow guide assembly 5 includes a rotating disc 19 and a hollow plate 23. The rotating disc 19 is fixedly installed at the bottom of the hollow sleeve 11. An inner baffle 27 is arranged at the inner side of the rotating disc 19. A filter screen 26 is arranged inside the hollow sleeve 11. A flow guide interlayer 28 is arranged between the top of the inner baffle 27 and the inner wall of the rotating disc 19. The inner cavity of the flow guide interlayer 28 is communicated with the inside of the hollow sleeve 11. A shunt plate 29 is arranged at the side edge of the inner baffle 27. The hollow plate 23 is fixedly installed at the bottom of the rotating disc 19. A center hole 25 is formed in the middle of the hollow plate 23. A discharge channel 24 is connected to the bottom of the center hole 25. The bottom of the discharge channel 24 passes through the inside of the discharge port 7, and the side edge of the discharge channel 24 is fitted with the inner wall of the discharge port 7. The side edge of the rotating disc 19 abuts against the inner wall of the surrounding plate 8. A sliding rail 20 is arranged at the top of the rotating disc 19. A telescopic channel 10 is arranged at the top of the storage tank 1. A first lifting rod 21 is installed inside the telescopic channel 10. A roller 22 is installed at the bottom of the first lifting rod 21. The first lifting rod 21 is embedded into the inside of the sliding rail 20 through the roller 22 at the bottom.

[0029] Specifically, when discharging, the flow guide assembly 5 is directly rotated through the driving mechanism 2. The rotating disc 19 is lowered through the control of the first lifting rod 21 until the hollow plate 23 at the bottom of the rotating disc 19 is fitted with the surface of the titanium dioxide. At this time, even if the titanium dioxide surface has been caked, the friction crushing effect can still be provided through the rotation of the hollow plate 23. In this process, the top air supply pipeline 18 is connected with the external air blower. The air blower is started to blow the external airflow into the inside. The airflow enters the inside of the flow guide interlayer 28 along the hollow sleeve 11 and flows downward from the side edge of the flow guide interlayer 28. Finally, the airflow is blown toward the middle from the position of the shunt plate 29. Due to the rotating effect of the bottom hollow plate 23, the titanium dioxide at the bottom can be lifted. The lifted titanium dioxide dust can only be blown into the inside of the discharge channel 24 at the bottom from the center hole 25 in the middle under the blowing of the airflow. Finally, it is discharged to the outside from the bottom of the discharge channel 24. In this process, the amount of titanium dioxide in the storage cavity 6 gradually decreases as the titanium dioxide is discharged. Therefore, the first lifting rod 21 continuously controls the downward movement of the rotating disc 19. The titanium dioxide at the bottom is discharged and processed in the process of friction and downward movement.

[0030] The driving mechanism 2 includes a transmission box 15 and a transmission sleeve 13. The transmission box 15 is fixedly installed on the top of the storage tank 1. A motor 16 is fixedly installed on the top of the transmission box 15. The transmission sleeve 13 is inserted into the middle position of the top of the storage tank 1. The surface of the transmission sleeve 13 is movably connected to the storage tank 1 through a bearing. A transmission gear 14 is fixedly installed on the surface of the transmission sleeve 13. The side of the transmission box 15 is provided with a hole. The side of the transmission gear 14 penetrates into the inside of the transmission box 15 from the hole of the side of the transmission box 15. The output shaft of the motor 16 is engaged with the transmission gear 14 through a gear structure. The surface of the hollow sleeve 11 is provided with a convex rod 12. The hollow sleeve 11 is embedded on the inner wall of the transmission sleeve 13 through the convex rod 12. The top of the hollow sleeve 11 is connected with a gas conveying pipeline 18 through a butt joint bearing 17. The gas conveying pipeline 18 is connected with an external air blower device. The internal flow guide assembly 5 cooperates with the top driving mechanism 2 to rotate and move downward regularly. In the case of not conveying air, the bottom hollow plate 23 can be extruded and rubbed with the surface area of the titanium dioxide powder accumulated at the bottom. Through this process, the titanium dioxide powder on the surface area can be crushed to ensure that the titanium dioxide powder on the surface layer can further reduce the probability of moisture and caking.

[0031] Specifically, the driving mechanism 2 controls the rotation of the driving shaft at the bottom through the motor 16. The gear on the driving shaft cooperates with the external transmission gear 14 to rotate, which can drive the hollow sleeve 11 in the middle to rotate. The surface of the hollow sleeve 11 is embedded with the inner wall of the transmission sleeve 13 through the convex rod 12. Therefore, the hollow sleeve 11 can rotate while being lifted and lowered by the first lifting rod 21. Therefore, the hollow sleeve 11 drives the rotating disc 19, the hollow plate 23 at the bottom, and the discharge channel 24 at the bottom to rotate. At the same time, the first lifting rod 21 cooperates with the roller 22 at the bottom to rotate in the slide rail 20. The lifting and lowering control process of the entire rotating disc 19 in the rotating state is realized. The top of the hollow sleeve 11 is movably connected with the gas conveying pipeline 18 through the butt joint bearing 17. The rotation of the hollow sleeve 11 does not drive the gas conveying pipeline 18 to rotate synchronously. The airflow in the gas conveying pipeline 18 is kept in communication with the inside of the hollow sleeve 11.

[0032] The drying assembly 3 comprises a drying box 34 and a cover plate 31, the inside of the drying box 34 is provided with a drying particle storage cavity 35, and the top of the drying box 34 is provided with an annular opening 38, the side of the storage tank 1 is welded with a fixing plate 37, the bottom of each fixing plate 37 is provided with a second lifting rod 32, the bottom of the second lifting rod 32 is fixedly connected with the surface of the cover plate 31, the bottom of the cover plate 31 is provided with a sealing ring 33, the sealing ring 33 is aligned with the annular opening 38 at the top of the drying box 34, the inside of the drying particle storage cavity 35 is filled with drying agent particles, and the inner wall of the drying particle storage cavity 35 is provided with an air inlet hole 36, and the inside of the drying particle storage cavity 35 is connected with the inside of the airflow guide channel 9 through the air inlet hole 36. The inside of the storage cavity 6 is extracted by the flow guide assembly 5 towards the top, and the side drying assembly 3 is opened, so that the air flow exchange of the top cavity of the storage cavity can be quickly realized, and the drying degree of the inside of the storage cavity 6 is enhanced.

[0033] Specifically, after the drying agent particles are put into the inside of the drying particle storage cavity 35, the flow guide assembly 5 is controlled to move to the top, at this time, the airflow in the hollow sleeve 11 is extracted by the external air blower, at this time, since the bottom discharge port 7 is always in a closed state, the external air can be extracted from the annular opening 38 on the drying particle storage cavity 35 and enters the airflow guide channel 9 from the air inlet hole 36, and then enters the storage cavity, and finally enters the inside of the flow guide assembly 5 from the bottom of the perforated plate 23 and is discharged, in this process, the original air in the storage cavity 6 can be replaced, and the dried air can be replaced, and when discharging, the second lifting rod 32 drives the bottom cover plate 31 and the sealing plate to move downward, so that the annular opening 38 is closed, and the airflow generated in the above discharge process is prevented from entering the drying particle storage cavity 35.
