[0002] Hydrotalcite is an anionic layered compound. Catalytically active species are inserted into the interlayers of hydrotalcite. Using hydrotalcite as a precursor, highly dispersed composite metal oxide catalysts can be prepared through calcination.

[0045] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0046] Example 1:

[0047] Please combine Figure 1-4, This embodiment. An intelligent and efficient titanium-based hydrotalcite catalyst preparation system, including a drying box 18 and a hopper 1, the inner wall of the drying box 18 is equipped with an electric heater, the bottom surface of the drying box 18 is provided with a channel for the hopper 1 to enter and exit, and also includes

[0048] The stirring mechanism includes a hollow fixed shaft 2 installed on the top of the drying box 18, a fixed cover 19 movably sleeved on the outside of the fixed shaft 2, a fixed plate 7 fixed on the outer periphery of the fixed shaft 2, a mounting plate 21 movably mounted on the bottom of the fixed plate 7 and a plurality of retractable stirring rods installed on the bottom of the mounting plate 21. The top of the fixed shaft 2 extends to the outside of the drying box 18. A driving motor for driving the fixed shaft 2 to rotate is installed on the top of the drying box 18. The stirring rod includes a movable rod 9 and a fixed cylinder 8 movably sleeved on the outside of the movable rod 9. The top of the fixed cylinder 8 is fixedly connected to the bottom surface of the mounting plate 21, and the bottom of the movable rod 9 extends into the hopper 1. The outer wall of the fixed cylinder 8 is threadedly connected with a locking bolt, and one end of the locking bolt abuts against the outer wall of the movable rod 9. After loosening the locking bolt, the height of the movable rod 9 can be adjusted to adapt to stirring under different circumstances.

[0049] A humidity sensor 35 is installed on the bottom surface of the fixed cover 19, and the fixed cover 19 is fixedly connected to the top of the drying box 18. The humidity sensor can monitor the air humidity inside the drying box 18, thereby providing it to the staff to facilitate the staff to finish drying. The external movable sleeve of the fixed shaft 2 is provided with a gear ring 3, and the gear ring 3 is fixed to the top inner wall of the fixed cover 19. A driving component is installed on the fixed plate 7. The driving component is connected to the gear ring 3 and is used to drive the mounting plate 21 to move back and forth when the fixed shaft 2 rotates. The top surface of the fixed plate 7 is provided with a connecting groove 43 arranged along its length direction, and a connecting block 20 is slidably connected in the connecting groove 43. The connecting block 20 The bottom extends to the bottom of the fixed plate 7 and is fixed to the top of the mounting plate 21. The top of the connecting block 20 extends to the top of the fixed plate 7 and is fixed with a movable plate 6. The length of the movable plate 6 is greater than the length of the connecting groove 43. The driving assembly includes a transmission gear 4 rotatably connected to the top of the fixed plate 7 and a connecting rod 5 hinged on the top surface of the transmission gear 4 at a position deviating from the center of the circle. The other end of the connecting rod 5 is hinged to the top surface of the movable plate 6, and the transmission gear 4 is meshed with the ring gear 3. In order to ensure that the material can pass normally, gaps are provided between adjacent stirring rods. After the movable plate 6 moves back and forth, it can ensure that the material between the gaps of the stirring rods can also be fully stirred.

[0050] The crushing mechanism includes a movable sleeve 10 and a connecting ring 39 arranged outside the fixed shaft 2, and a pressure roller 17 installed at the bottom of the movable sleeve 10 through a mounting frame 16. A limit plate arranged along its axial direction is fixed on the outer wall of the fixed shaft 2, and a limit groove arranged along its axial direction is opened on the inner wall of the movable sleeve 10. One side of the limit plate is slid into the limit groove, thereby ensuring that the movable sleeve 10 can only move axially along the fixed shaft 2. The connecting ring 39 is rotatably connected to the movable sleeve 10, and a telescopic part three 37 for driving the movable sleeve 10 to move is installed between the connecting ring 39 and the ring gear 3. The telescopic part three 37 is an electric telescopic rod, which drives the movable sleeve 10 to rise and fall by the extension and contraction of the telescopic part three 37, so that the pressure roller 17 will not contact the material during drying. After the drying is completed, the pressure roller 17 will start to descend and crush the material.

[0051] The exhaust mechanism includes a connecting cover 15 installed on the top of the mounting frame 16 and a bellows 14 installed on the connecting cover 15. The connecting cover 15 is provided with a plurality of air inlet holes. A fan 41 is installed in the bellows 14, and an air intake pipe communicating with the interior of the connecting cover 15 is installed on one side of the bellows 14. An air outlet pipe 40 communicating with the interior of the fixed shaft 2 is installed on the other side of the bellows 14. The air outlet pipe 40 is a retractable hose. A linkage assembly for driving the fan 41 to rotate is installed between the bellows 14 and the ring gear 3. The linkage assembly includes a transmission shaft 36 installed on the outer wall of the fixed shaft 2, a linkage shaft 44 installed on the bellows 14 and a connecting shaft 46. A connecting gear 11 meshing with the ring gear 3 is fixed on the top of the transmission shaft 36. A driving bevel gear is fixed to the bottom of 36, and a driving gear 13 and a driven bevel gear 12 that cooperates with the driving bevel gear are sleeved on the outside of the linkage shaft 44. One end of the connecting shaft 46 is fixedly connected to the driven gear 38 that meshes with the driving gear 13, and the other end of the connecting shaft 46 extends into the bellows 14 and is transmission-connected to the fan 41. When the driven main gear and the driving bevel gear are in meshing, the fan 41 rotates with the rotation of the fixed shaft 2, so that the water vapor in the drying box 18 can be pumped to the outside of the drying box 18. After the driven main gear and the driving bevel gear are out of meshing, the fan 41 will not rotate, thereby avoiding the waste of material caused by pumping the material to the outside of the drying box 18 during the crushing process.

[0052] The implementation principle of this embodiment is as follows: during drying, the hopper 1 is kept inside the drying box 18, and then the electric heater in the drying box 18 is started. The temperature inside the drying box 18 rises, and the moisture in the material inside the hopper 1 begins to evaporate under the high temperature. The driving motor is started, so that the fixed shaft 2 starts to rotate, and the fixed plate 7 rotates synchronously with the fixed shaft 2, so that the stirring rod can stir the material in the hopper and accelerate the dissipation of moisture in the material. Since the ring gear 3 does not rotate, the transmission gear 4 rotates along the outer circumference of the ring gear 3 while the fixed plate 7 rotates following the fixed shaft 2, thereby driving the movable plate 6 to move back and forth on the top surface of the fixed plate 7, thereby allowing the multiple stirring rods to move back and forth along the diameter direction of the hopper 1;

[0053] When adjusting the length of the stirring rod, first loosen the locking bolt, then move the movable rod 9, and tighten the locking bolt after adjustment. The movable rod 9 can be locked by relying on the static friction between the locking bolt and the pulp on the movable rod.

[0054] While drying the material, the driven bevel gear 12 is kept in meshing with the driving bevel gear. The connecting gear 11 rotates along with the fixed shaft 2 due to the meshing with the ring gear 3, so that the driving bevel gear can drive the driven bevel gear 12 to rotate while the fixed shaft 2 rotates. After the driven bevel gear 12 rotates, it drives the driving gear 13 to rotate. The driving gear 13 then drives the driven gear 38 to rotate, thereby rotating the fan 41.

[0055] After drying is completed, the telescopic part 37 is started to extend, and the movable sleeve 10 is lowered, thereby separating the driving bevel gear from the driven bevel gear 12, and the fan 41 stops rotating until the pressure roller 17 is pressed on the top surface of the material in the hopper 1, and then the telescopic part 37 is stopped from extending, and the pressure roller 17 rotates synchronously with the rotation of the fixed shaft 2, thereby crushing the agglomerated material during the drying process, and the stirring rod can further stir the crushed material to ensure that the material is crushed more fully.

[0056] Example 2:

[0057] Combine Figure 2-5, based on Example 1, this embodiment is further improved in that it also includes an adjusting mechanism, which is installed at the bottom of the hopper 1 and is used to drive the hopper 1 to rise and fall and rotate. A stacking plate 22 is provided inside the hopper 1, and a connecting plate 23 is hinged at the bottom of the stacking plate 22. A telescopic member 24 is installed on the inner wall of the bottom of the hopper 1, and the telescopic end of the telescopic member 24 is fixedly connected to the bottom surface of the connecting plate 23. The interior of the hopper 1 consists of a drying area and a discharge area. The discharge area is located at the bottom of the drying area, and the inner diameter of the discharge area is larger than the inner diameter of the drying area. The stacking plate 22 is located in the discharge area, and the diameter of the stacking plate 22 is larger than the inner diameter of the drying area. A discharge hole communicating with the discharge area is provided on the outer wall of one side of the hopper 1. 26. A receiving plate 27 is fixed to the inner bottom of the discharge hole 26, and a limiting block 25 is fixed on the inner wall of the discharge hole 26 in the discharge area, and the vertical distance between the limiting block 25 and the drying area is smaller than the vertical distance between the receiving plate 27 and the drying area. When the top surface of the stacking plate 22 touches the bottom of the drying area, it will stop rising, so that the stacking plate 22 can maintain a horizontal state, and the setting of the limiting block 25 makes it possible for the stacking plate 22 to touch the limiting block 25 during the descent process. The side of the stacking plate 22 away from the limiting block 25 will gradually tilt as the stacking plate 22 continues to descend, so that the material on the top surface of the stacking plate 22 can be discharged smoothly from the discharge hole 26.

[0058] The adjusting mechanism includes a base plate 33, a rotating shaft 29 fixed to the top surface of the base plate 33, a lifting plate 28 fixed to the bottom surface of the hopper 1 and two threaded rods 34 rotatably connected to the top surface of the base plate 33. Fixed blocks 45 are fixed at both ends of the lifting plate 28, and the two fixed blocks 45 are respectively threadedly sleeved on the outside of the two threaded rods 34. The two threaded rods 34 are connected by a chain transmission. The lifting plate 28 is movably sleeved on the outside of the rotating shaft 29. A motor for driving the threaded rods 34 to rotate is installed on the top of the base plate 33. A plurality of positioning columns 47 are fixed to the bottom surface of the lifting plate 28. A steering assembly for driving its rotation is also installed under the base plate 33. When the motor drives one of the threaded rods 34 to rotate, the two threaded rods 34 rotate at the same time. When the two threaded rods 34 rotate forward, the lifting plate 28 can be driven to move upward. Conversely, when the threaded rods 34 are reversed, the lifting plate 28 is driven downward.

[0059] The steering assembly includes a base 32 fixed to the ground, a telescopic member 2 30 installed on the top of the base 32 and a rack 31 fixed to the extended end of the telescopic member 2 30. The telescopic member 2 30 is an electric telescopic rod. The bottom of the rotating shaft 29 extends to the bottom of the bottom plate 33 and is rotatably connected to the top of the base 32. The outer portion of the rotating shaft 29 is sleeved with a fixed gear engaged with the rack 31. A plurality of casters are installed at the bottom of the bottom plate 33. The setting of the casters serves to support the bottom plate 33. The bottom plate 33 is driven to rotate by the extension and contraction of the telescopic member 2 30, so that the hopper can be rotated to a position deviating from the position directly below the drying box 18, which is convenient for loading and unloading.

[0060] The implementation principle of this embodiment is that when discharging, the motor is first started to drive the two threaded rods 34 to reverse, so that the hopper 1 starts to descend, until the hopper 1 is completely lowered to the outside of the drying box 18, and then the telescopic part 2 30 is started to extend, so that the rotating shaft 29 rotates, thereby gradually rotating the hopper 1 to a position deviating from the bottom of the drying box 18, and then after the telescopic part 2 30 stops extending, the telescopic part 1 24 is started to contract, so that the stacking plate 22 descends. When the stacking plate 22 hits the limit block 25, the side of the stacking plate 22 away from the limit block 25 will gradually tilt during the continued descent of the stacking plate 22, so that the material on the top surface of the stacking plate 22 can be discharged smoothly from the discharge hole 26.

[0061] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
