[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a high-efficiency mixing device for the preparation of ultra-dry anhydrous reagents, which has the following beneficial effects:

[0017] 1. This high-efficiency mixing device for preparing ultra-dry anhydrous reagents uses a second servo motor to drive the mounting shaft, stirring shaft, and stirring blades to rotate, thereby mixing the raw materials in the mixing tank. Simultaneously, a dual-axis servo motor drives two drive bevel gears to rotate, which in turn drive two driven bevel gears to rotate two second threaded rods. During rotation, the two threaded rods cause the moving block, mounting shaft, stirring shaft, and stirring blades to move upwards. Then, the dual-axis servo motor rotates in the opposite direction, causing the two threaded rods to rotate in the opposite direction, thus moving the moving block, mounting shaft, stirring shaft, and stirring blades downwards. The dual-axis servo motor then rotates forward again, and this cycle repeats, causing the stirring shaft and stirring blades to move up and down. This, combined with the up-and-down movement of the stirring blades during rotation, expands the mixing range, ensuring thorough mixing of the raw materials in the mixing tank. Ultimately, this improves the mixing effect and efficiency, benefiting the user.

[0018] 2. This high-efficiency mixing device for preparing ultra-dry anhydrous reagents uses two first servo motors to drive two drive gears to rotate, which in turn drive two first threaded rods to rotate via two driven gears. This causes the two traction blocks, cover plate, mounting shaft, stirring shaft, and stirring blades to move upwards as a whole, allowing the stirring shaft and stirring blades to move out of the mixing tank. Next, turning two handwheels drives two worm gears to rotate, which in turn drive two third threaded rods to rotate via two worm wheels. This causes two positioning blocks to move in opposite directions, allowing them to move out of their respective positioning slots, thus releasing the fixing of the connecting blocks. At this point, pulling down the stirring shaft and stirring blades allows for disassembly, facilitating cleaning of the stirring blades and improving usability. Attached Figure Description

[0036] In use, firstly, the vacuum pump 181 is started to extract the air from the mixing tank 3, thereby preventing moisture in the air from affecting the preparation of the ultra-dry anhydrous reagent. Next, the raw materials for the ultra-dry anhydrous reagent are injected into the mixing tank 3 through the feed pipe 15. Then, the second solenoid valve 16 is closed. The second servo motor 23 is then started to drive the mounting shaft 24, stirring shaft 28, and stirring blades 29 to rotate, thereby stirring and mixing the raw materials in the mixing tank 3. Simultaneously, the dual-axis servo motor 221 can be started to drive the two drive bevel gears 222 to rotate, which in turn drives the two driven bevel gears 222 to rotate. The 23rd motor drives the two second threaded rods 19 to rotate. During this rotation, the two second threaded rods 19 cause the moving block 21, mounting shaft 24, stirring shaft 28, and stirring blades 29 to move upwards as a whole. Then, the dual-axis servo motor 221 rotates in the opposite direction, causing the two second threaded rods 19 to rotate in the opposite direction. At this time, the two second threaded rods 19, during their rotation, cause the moving block 21, mounting shaft 24, stirring shaft 28, and stirring blades 29 to move downwards as a whole. Then, the dual-axis servo motor 221 rotates forward again, and this cycle repeats, causing the stirring shaft 28 and stirring blades 29 to move upwards. The stirring blades 29 move up and down in coordination with the rotation, thereby expanding the stirring range and ensuring thorough mixing of the raw materials in the mixing tank 3. This improves the mixing effect and efficiency. After mixing is complete, the first solenoid valve 5 is opened to discharge the raw materials through the discharge pipe 4. When cleaning the stirring blades 29 is required, the two first servo motors 101 are activated to drive the two drive gears 102 to rotate, which in turn drive the two first threaded rods 8 to rotate via the two driven gears 103. This, in turn, drives the two traction blocks 9, the cover plate 12, and the mounting shaft. 24. The stirring shaft 28 and stirring blades 29 are moved upward as a whole to remove them from the inside of the mixing tank 3. Then, the two handwheels 343 can be turned to drive the two worm gears 342 to rotate, which in turn drives the two third threaded rods 31 to rotate through the two worm wheels 341. This causes the two positioning blocks 33 to move in opposite directions, so that the two positioning blocks 33 are removed from the inside of the two positioning slots 32, thereby releasing the fixing of the connecting block 27. At this time, the stirring shaft 28 and stirring blades 29 can be pulled downward to disassemble them, which makes it easier to clean the stirring blades 29.

[0037] In summary, this high-efficiency mixing device for preparing ultra-dry anhydrous reagents uses the second servo motor 23 to drive the mounting shaft 24, stirring shaft 28, and stirring blades 29 to rotate, thereby mixing the raw materials in the mixing tank 3. Simultaneously, the dual-axis servo motor 221 drives two driving bevel gears 222 to rotate, which in turn drives two driven bevel gears 223 to rotate two second threaded rods 19. During rotation, the two second threaded rods 19 cause the moving block 21, mounting shaft 24, stirring shaft 28, and stirring blades 29 to move upwards as a whole, which in turn causes the dual-axis servo motor 221 to... The reverse rotation drives the two second threaded rods 19 to rotate in the opposite direction. During this rotation, the two second threaded rods 19 cause the moving block 21, mounting shaft 24, stirring shaft 28, and stirring blades 29 to move downwards as a whole. Then, the dual-axis servo motor 221 rotates forward again, and this cycle repeats, driving the stirring shaft 28 and stirring blades 29 to move up and down. This causes the stirring blades 29 to move up and down in coordination with the rotation, thus expanding the mixing range and enabling comprehensive mixing of the raw materials in the mixing tank 3. Ultimately, this improves the mixing effect and efficiency of the raw materials, which is beneficial for use. In the user's operation, the two first servo motors 101 are activated to drive the two drive gears 102 to rotate, which in turn drive the two driven gears 103 to rotate the two first threaded rods 8. This causes the two traction blocks 9, cover plate 12, mounting shaft 24, stirring shaft 28, and stirring blades 29 to move upward as a whole, so that the stirring shaft 28 and stirring blades 29 are moved out of the mixing tank 3. Then, the two handwheels 343 are turned to drive the two worm gears 342 to rotate, which in turn drive the two third threaded rods 31 to rotate through the two worm wheels 341. This causes the two positioning blocks 33 to move in opposite directions, so that the two... The positioning blocks 33 are removed from the inside of the two positioning slots 32, thereby releasing the fixing of the connecting block 27. At this time, the stirring shaft 28 and stirring blade 29 can be removed by pulling them down, which facilitates the cleaning of the stirring blade 29 and makes it easier to use. This solves the problems of existing mixing devices, where the stirring blades are mostly fixed in position, resulting in a limited mixing range, poor mixing effect and low efficiency. In addition, the stirring blades in the device are not easy to disassemble, making it inconvenient to clean them and thus hindering their use.
