Description

Technical Field

[0001] The invention relates to the technical field of niobium oxide preparation, in particular to a device for preparing high-purity niobium oxide. Background Art

[0002] High-purity niobium oxide is an important inorganic compound, which is often used in electronic materials, optical materials, catalysts and other fields. One of the common preparation methods of niobium oxide is the sol-gel method, which mixes niobium compounds such as ammonium niobate with a suitable solvent to form a sol, then converts the sol into a gel through a suitable heating and drying process, and further heat treats it to convert it into niobium oxide gel, and finally, the niobium oxide gel is subjected to a high-temperature calcination treatment to convert it into niobium oxide powder.

[0003] However, the single axial stirring device in the existing preparation equipment cannot fully stir the solution inside the device during the stirring process of the solution, especially precipitation may occur at the edge of the device, resulting in an incompletely dissolved structure, affecting the subsequent preparation of niobium oxide and affecting the performance and application of the finished product. Summary of the invention

The bottom plate 406 and the first connection rod 403 will contact with the internal solvent during the downward movement, and will be gradually opened outward by the liquid pressure. In the upward movement, they will also be gradually contracted toward the center by the liquid pressure. The side of the threaded connection seat 409 is threadedly connected with a threaded sleeve 411. The side of the threaded sleeve 411 is fixedly connected with a limiting disk 412. The limiting disk 412 is movably connected with a movable ball 413, a connecting rod 414 and a stirring blade 415.

[0006] The top of the central connecting tube 2 is fixedly connected with a top connecting device 3, and the top connecting device 3 includes an outer shell plate 301, and a movable rod 304 is arranged at the bottom of the outer shell plate 301. The top of the movable rod 304 is fixedly connected with a motor 1, and the motor 1 is arranged inside the outer shell plate 301. The bottom of the movable rod 304 is fixedly connected with a threaded connecting rod 308, and the bottom of the outer shell plate 301 is fixedly connected with a bottom connecting shell 307, and the bottom of the bottom connecting shell 307 is fixedly connected with a connecting rod 309. The bottom of the threaded connecting rod 308 is threadedly connected with a limiting sleeve rod 410, and the limiting sleeve rod 410 is sleeved on the connecting rod 309 and threadedly connected with the connecting rod 309. The threaded connecting rod 308 can perform forward and reverse motion under the drive of the motor 1, thereby driving the limiting sleeve rod 410 threadedly connected to the bottom of the threaded connecting rod 308 to rotate on the outer layer of the connecting rod 309, so as to control the stirring device 4 to reciprocate up and down in a rotating state inside the central connecting tube 2.

[0007] Furthermore, a movable groove in the vertical direction is opened on the inner wall of the limiting plate 412. The movable groove is offset by 60 degrees at both ends based on the normal line, and one movable groove is provided at the top and the bottom.

[0008] Furthermore, a connecting rod 414 is fixedly connected to the center of the movable ball 413, and the connecting rod 414 is arranged at a movable groove on the inner wall of the limiting plate 412 and is movably connected to the limiting plate 412. The stirring blade 415 is arranged on the outer side of the movable ball 413 and is fixedly connected to the movable ball 413.

[0009] Furthermore, a connecting groove is opened at the center of the No. 1 connecting rod 403, and a No. 2 connecting rod 404 is arranged at the connecting groove. The No. 2 connecting rod 404 and the No. 1 connecting rod 403 are connected to the connection between the No. 1 connecting rod 403 and the bottom plate 406 through a pin. The other end of the No. 2 connecting rod 404 is rotatably connected to a connecting disk 405, and a limiting sleeve rod 410 is fixedly connected at the center of the connecting disk 405.

[0010] Furthermore, a connecting plate 407 is provided at adjacent connection points of the bottom plate 406 . The connecting plate 407 is provided at the center of the bottom plate 406 and is movably connected to the bottom plate 406 .

[0011] During use, driven by the motor 1 inside 301, 304 and 308 start to rotate, and the outer side of 308 is threadedly connected with 410. The forward and reverse rotation of motor 1 controls the movement direction of 4. The forward rotation of motor 1 controls 4 to move downward on 309, and the reverse rotation of motor 1 controls 4 to move upward on 309.

[0012] When the limiting sleeve 410 moves downward driven by the threaded connecting rod 308, it will come into contact with the liquid at the bottom during the movement. After being subjected to the pressure of the water, the bottom plate 406 and the connecting plate 407 gradually expand outward, driving the No. 1 connecting rod 403 and the No. 2 connecting rod 404 connected thereto to expand outward, thereby expanding the stirring range of the movable ball 413, the connecting round rod 414 and the stirring fan blade 415 set on the connecting block 408, and can stir the bottom and the inner wall of the central connecting tube 2, reduce the precipitation amount of ammonium niobate, and thus increase the output; when the limiting sleeve 410 moves upward driven by the threaded connecting rod 308, the stirring device 4 gradually moves upward from the liquid, and the connecting rod 308 is connected to the bottom plate 406 and the connecting plate 407. The connecting sleeve 401 moves upward under the action of water pressure, driving the No. 1 connecting rod 403 and the No. 2 connecting rod 404 to shrink inward, driving the bottom plate 406 and the connecting plate 407 set at the bottom to shrink inward. Compared with the downward movement, the pressure in the vertical direction is smaller at this time, and the thread inside the limiting sleeve 410 is less stressed. A larger output power can be used to increase the rotation speed of the stirring device 4. During stirring, the ammonium niobate entering from the feed hole 310 can be fully stirred, thereby increasing the stirring rate of the ammonium niobate. The connecting sleeve 401, the No. 1 connecting rod 403 and the No. 2 connecting rod 404 can balance the force applied to the stirring device 4 when in use, so that the device is more evenly stressed.

[0014] Furthermore, a movable disc 305 is fixedly connected to the movable rod 304 , a fan blade plate 306 is fixedly connected to the side of the movable disc 305 , and a feeding hole 310 is opened at the bottom of the bottom connection shell 307 .

[0015] Furthermore, the inner bottom surface of the outer shell plate 301 is inclined toward the movable rod 304, and the inclination degree is between forty-five and fifty-five degrees.

[0016] During use of the device, ammonium niobate is put into the outer shell plate 301, and the ammonium niobate slides down along the inner wall of the outer shell plate 301 and is crushed by the crushing device 303. The baffle 302 can prevent fragments from splashing out from the outer shell plate 301 and injuring people during the crushing process. After the ammonium niobate is crushed, it will enter the bottom connecting shell 307. The movable rod 304 drives the movable disk 305 and the fan blade plate 306 fixedly connected to the side of the movable disk 305 to rotate. While rotating, the fan blade plate 306 sweeps the ammonium niobate into the groove at the bottom connecting shell 307, and enters the interior of the central connecting cylinder 2 through the feed hole 310 set at the bottom of the bottom connecting shell 307. The crushing process of the ammonium niobate helps to increase the dissolution rate and dissolution amount of the ammonium niobate, thereby increasing the output.

[0017] Beneficial effects:
