[0020] See also Figure 1-3 The utility model provides a technical solution: a silicon dioxide blast drying and conveying device, comprising a drying tank 1, and also comprising a linkage mechanism. The drying tank 1 is provided with a feeding port 3, a fixing seat 4 is fixedly provided on the top outer wall of the drying tank 1, a hot air pipe groove 5 is opened on the fixing seat 4, and a stirring shaft groove 7 is opened at the bottom of the hot air pipe groove 5. A hot air pipe 6 is connected in the hot air pipe groove 5, and a stirring shaft 8 is rotatably arranged in the stirring shaft groove 7. The stirring shaft 8 is a hollow shaft and is connected to the hot air pipe 6. A motor 9 is fixedly provided on one side of the fixing seat 4 of the drying tank 1, and the output end of the motor 9 passes through the inner wall of the top of the drying tank 1 and is linked with the stirring shaft 8 through the linkage mechanism. A plurality of stirring rods 14 are fixedly and evenly arranged on the outer wall of the stirring shaft 8, and a plurality of groups are evenly arranged along the axial direction of the stirring shaft 8. The stirring rod 14 is hollow and is connected to the inside of the stirring shaft 8. A plurality of air holes 16 are evenly opened on the stirring rod 14. A discharge pipe 17 is provided at the bottom of the drying tank 1, and a discharge valve 18 is provided in the discharge pipe 17.

[0021] Specifically, the linkage mechanism includes a driving gear 10 and a driven gear 11. The driving gear 10 is fixedly sleeved on the output shaft of the motor 9, and the driven gear 11 is fixedly sleeved on the stirring shaft 8 and meshed with the driving gear 10. The motor 9 drives the driving gear 10 to rotate, and the driven gear 11 is driven to rotate through the meshing of the driving gear 10 and the driven gear 11, thereby causing the stirring shaft 8 to rotate.

[0022] Specifically, the outer wall of the hot air pipe 6 is in contact with the inner wall of the hot air pipe groove 5, and the hot air pipe 6 is inserted into the inner wall of the stirring shaft 8 and is tightly abutted to ensure the inflow of hot air. A bearing groove 12 is opened on the inner wall ring of the stirring shaft groove 7 and multiple bearings are arranged along the axial direction of the stirring shaft groove 7. A bearing 13 with an inner ring fixedly connected to the outer wall of the stirring shaft 8 is rotatably arranged in the bearing groove 12. The stirring shaft 8 can rotate without axial displacement due to the limiting of the bearing 13.

[0023] Specifically, a plurality of stirring paddles 15 are evenly fixed on the side wall of the stirring rod 14. The stirring paddle 15 is a hollow structure and is connected to the stirring rod 14. A plurality of air holes 16 are provided on the stirring paddle 15. The stirring shaft 8 rotates to drive the stirring rod 14 and the stirring paddle 15 to rotate, thereby more fully stirring the silicon dioxide. Hot air flows out from the air holes 15 to cooperate with the rotation of the stirring rod 14 and the stirring paddle 15, so that the hot air is evenly and fully in contact with the silicon dioxide, thereby ensuring the drying effect of the silicon dioxide and improving the drying efficiency of the silicon dioxide.

[0024] Specifically, a scraper 20 attached to the inner wall of the drying tank 1 is fixedly disposed at one end of the stirring rod 14 away from the stirring shaft 8 . The scraper 20 scrapes the inner wall of the drying tank 1 as the stirring rod 14 rotates to prevent silicon dioxide from remaining on the inner wall of the drying tank 1 .

[0025] Specifically, spiral blades 19 are symmetrically arranged on the stirring shaft 8. The upper and lower spiral blades 19 have opposite rotation directions. The spiral blades 19 rotate with the stirring shaft 8. When the spiral blades 19 with opposite rotation directions rotate, they push the silicon dioxide on the upper and lower sides toward the middle, so that the silicon dioxide can be continuously turned over, thereby improving the drying efficiency and drying effect of the silicon dioxide.

[0026] A specific application example of this embodiment is:

[0027] When the device is in use, silicon dioxide is put in from the feed port 3, the hot air pipe 6 is connected to a hot air blower, the hot air is passed from the hot air pipe 6 into the stirring shaft 8 and then into the stirring rod 14 and the stirring paddle 15, and finally dispersed from the air hole 16, the motor 9 is started, the motor 9 drives the driving gear 10 to rotate, and the driven gear 11 is driven to rotate through the meshing of the driving gear 10 and the driven gear 11, so that the stirring shaft 8 rotates, and the rotation of the stirring shaft 8 drives the stirring rod 14 to rotate and drives the stirring paddle 15 to rotate, so that the silicon dioxide is fully stirred, and the hot air is dispersed from the air hole 15 to cooperate with the stirring rod 14 and the stirring paddle 15. The rotation of the stirring paddle 15 allows the hot air to evenly and fully contact the silicon dioxide, ensuring the drying effect of the silicon dioxide and improving the drying efficiency of the silicon dioxide. The spiral blades 19 rotate with the stirring shaft 8. When the spiral blades 19 rotate in opposite directions, the silicon dioxide on the upper and lower sides are pushed toward the middle, so that the silicon dioxide can be continuously turned over, further improving the drying efficiency and drying effect of the silicon dioxide. The scraper 20 rotates with the stirring rod 14 to prevent the silicon dioxide from sticking to the inner wall of the drying tank 1. After the drying is completed, the discharge valve 18 is opened to discharge the silicon dioxide from the discharge pipe 17.
