[0019] like Figure 1-Figure 7 As shown, a nano-zirconia granulation powder production device of the present invention comprises a kettle mechanism, a driving mechanism is fixedly installed on the upper surface of the kettle mechanism, a lifting mechanism is fixedly installed on the upper surface of the kettle mechanism, a stirring mechanism is arranged inside the kettle mechanism, and the upper end of the stirring mechanism passes through the driving mechanism and extends into the lifting mechanism; The kettle body mechanism comprises a kettle body 11, a processing cavity 12 is provided inside the kettle body 11, and a mounting cavity 13 is provided on the inner wall of the kettle body 11; The driving mechanism includes a fixing hole 21, which is opened on the upper end wall of the processing cavity 12, a bearing 22 is fixedly installed on the hole wall of the fixing hole 21, a rotating rod 23 is fixedly installed on the bearing 22, and a rectangular hole 27 is penetrated through the rotating rod 23; The lifting mechanism includes a fixed frame 31, which is fixedly mounted on the upper surface of the kettle body 11, and a support block 32 is fixedly mounted on the fixed frame 31. A lifting cavity 33 is provided inside the support block 32, and a moving hole 34 is provided through the lower end cavity wall of the lifting cavity 33. A reciprocating thread is provided on the cavity wall of the lifting cavity 33, and a reciprocating thread block 35 is connected to the inner thread of the lifting cavity 33. The stirring mechanism includes a rectangular rod 41, which is slidably connected in the rectangular hole 27. The lower end of the rectangular rod 41 extends into the processing chamber 12 and is fixedly connected to an extrusion plate 42. A through hole 43 is penetrated through the extrusion plate 42. A stirring rod 44 is fixedly installed on the rod wall of the rectangular rod 41 located in the processing chamber 12. The upper end of the rectangular rod 41 extends to the lifting chamber 33. One end of the rectangular rod 41 located in the lifting chamber 33 is fixedly connected to the lower surface of the reciprocating threaded block 35.

[0020] A heating coil 14 is fixedly mounted on the cavity wall of the installation cavity 13 , a discharge pipe 15 is fixedly mounted on the cavity wall at the lower end of the processing cavity 12 , and a feed pipe 16 is fixedly mounted on the cavity wall near the upper end of the processing cavity 12 .

[0021] Among them, the lower end of the discharge pipe 15 extends to the outside of the kettle body 11, and an electromagnetic valve 17 is fixedly installed on the discharge pipe 15. After the processing is completed, the electromagnetic valve 17 can be opened to allow the mixture after the reaction to be discharged to the outside through the discharge pipe 15. One end of the feed pipe 16 extends to the outside of the kettle body 11, and a check valve 18 is fixedly installed on the feed pipe 16 to connect the external conveying equipment with the feed pipe 16, and then the raw material is injected into the processing chamber 12 through the feed pipe 16, and the check valve 18 can prevent the raw material from retreating.

[0022] Among them, the upper end of the rotating rod 23 extends to the outside of the kettle body 11 and is fixedly installed with a first bevel gear 24. A driving motor 25 is fixedly installed on the upper surface of the kettle body 11. The output end of the driving motor 25 is fixedly installed with a second bevel gear 26 through a coupling.

The driving motor 25 drives the second bevel gear 26 to rotate, and the second bevel gear 26 drives the rotating rod 23 to rotate by meshing with the first bevel gear 24.

[0023] Among them, the through hole 43 is arranged in a funnel shape, and the aperture of the through hole 43 is arranged to decrease from top to bottom. When the extrusion plate 42 rises, the large aperture above the through hole 43 facilitates the collection of the mixture and discharges it downward, and when the extrusion plate 42 descends, the small aperture below will enhance the force of the mixture ejecting upward, thereby regulating the flow of the entire mixture.

[0024] Among them, the outer wall of the rectangular rod 41 fits with the inner wall of the rectangular hole 27, so that when the rotating rod 23 rotates, it will drive the rectangular hole 27 to rotate synchronously, and the rectangular hole 27 drives the rectangular rod 41 to rotate synchronously by clamping with the rectangular rod 41, and the rectangular rod 41 can rise and fall in the rectangular hole 27 while rotating.

[0025] The rectangular rod 41 is rotatably connected in the fixing hole 21 and the moving hole 34 , so that the fixing hole 21 and the moving hole 34 will not affect the rotation and lifting of the rectangular rod 41 .

[0026] A method for using a nano zirconium oxide granulation powder production device, Step 1: First, the driving motor 25 is started, and the driving motor 25 drives the rotating rod 23 to rotate through the meshing of the first bevel gear 24 and the second bevel gear 26, and the rotating rod 23 drives the rectangular rod 41 to rotate through the engagement between the rectangular hole 27 and the rectangular rod 41; Step 2: Connect the external conveying equipment to the feed pipe 16, and then inject the raw material into the processing chamber 12 through the feed pipe 16, and start the heating coil 14 when adding the raw material; Step 3: When the rectangular rod 41 rotates, it drives the reciprocating thread block 35 to rotate. When the reciprocating thread block 35 rotates, it reciprocates and rises and falls in the lifting chamber 33, and drives the rectangular rod 41 to rotate and rise and fall simultaneously. The rectangular rod 41 drives the extrusion plate 42 and the stirring rod 44 to move simultaneously, and the stirring rod 44 stirs the mixture. Step 4: The rise of the extrusion plate 42 will drive the mixture above it to rise synchronously, and transport part of the material downward through the through hole 43, so that the mixture flows up and down, making it convenient for the stirring rod 44 to stir the mixture at different heights; Step 5: When the extrusion plate 42 descends, the mixture at the bottom is pressurized, so that the pressurized mixture is ejected upward through the through hole 43, so that the mixture flows up and down, which facilitates the stirring rod 44 to stir the mixture at different heights (for example In this reaction, zirconium hydroxide For solid raw materials, hydrochloric acid As liquid, the two react to form zirconium oxychloride Solution and water. During the reaction, zirconium hydroxide gradually dissolves in the hydrochloric acid solution to form a uniform liquid mixture. After zirconium oxychloride is generated, the subsequent preparation of zirconium oxide powder requires multiple steps. First, evaporation and concentration are performed to increase the solution concentration, reduce the volume, and evaporate part of the water. Then cool and crystallize, lower the temperature to allow zirconium oxychloride to precipitate in the form of crystals to form a solid-liquid mixture. Then filter and wash to separate the crystals and remove impurities. Finally, calcination is performed to decompose the crystals, remove crystal water and other impurities, and generate zirconium oxide powder).

[0027] When in use, first start the drive motor 25 and the heating coil 14, and the drive motor 25 will drive the second bevel gear 26 to rotate, and the second bevel gear 26 drives the rotating rod 23 to rotate by meshing with the first bevel gear 24, and the rotating rod 23 rotates in the fixing hole 21 through the bearing 22, and the rotating rod 23 drives the rectangular rod 41 to rotate synchronously through the rectangular hole 27 and the clamping connection with the rectangular rod 41, and the rectangular rod 41 will drive the reciprocating thread block 35 to rotate, and the reciprocating thread block 35 will reciprocate and rise and fall in the lifting chamber 33 by meshing with the reciprocating thread, and the reciprocating thread block 35 will drive the rectangular rod 41 to rise and fall synchronously, and the rectangular rod 41 will drive the extrusion plate 42 and the stirring rod 44 to rise and fall and rotate synchronously, so that the extrusion plate 42 and the stirring rod 44 are lifted and lowered while rotating. At this time, the external conveying equipment is connected to the feed pipe 16, and then the raw materials are injected into the processing chamber 12 through the feed pipe 16. At this time, the stirring rod 44 mixes the raw materials and heats them. During the mixing process, when the extrusion plate 42 rises upward, the extrusion plate 42 will drive the mixture above it to rise synchronously, and transport part of the material downward through the through hole 43. After that, when the extrusion plate 42 descends downward, the mixture at the bottom will be pressurized, so that the pressurized mixture will spray upward through the through hole 43, and the stirring rod 44 will rise and fall while rotating, so that the overall flow of the mixture inside the processing chamber 12 is irregular, thereby avoiding the regular flow of the mixture causing insufficient internal heating and affecting the overall processing. After the processing is completed, the electromagnetic valve 17 can be opened to allow the mixture after the reaction to be discharged outward through the discharge pipe 15.
