By arranging the electric push rod 301 and the crushing rod 307, the crushing rod 307 can be driven to move up and down when the electric push rod 301 works, so that large-sized materials can be crushed. The bottom of the feeding hopper 303 is connected with a telescopic hose 306. By arranging the telescopic hose 306, the feeding hopper 303 can be connected with the calcining tube 2, and when the telescopic deformation occurs, it can still play a role in good communication. Small vibration motors 305 are installed on the left and right sides of the telescopic hose 306, and a reduction motor 4 is installed on the left bolt of the calcining cylinder 2. The output end of the reduction motor 4 is fixedly connected to a movable rod 9, and a spiral blade 7 is fixedly sleeved on the surface of the movable rod 9. By setting the spiral blade 7 and the movable rod 9, the movable rod 9 can drive multiple spiral blades 7 to rotate simultaneously under the drive of the reduction motor 4, thereby continuously conveying the material to the left. The inner wall of the calcining cylinder 2 is fixedly connected with a convex tooth 8. By setting the convex tooth 8, it can be protruded and arranged in the calcining cylinder 2, and then can contact with the transmitted material to achieve the purpose of extrusion friction and play a role in auxiliary crushing. The bottom of the left side of the inner cavity of the calcining cylinder 2 is connected with a discharge valve 5, and the bottom of the calcining cylinder 2 is fixedly installed with a heating calciner 6;

[0021] See also Figure 3 and Figure 5 The feeding hopper 303 is located at the top of the fixed frame 1, and the bottom of the telescopic hose 306 passes through the fixed frame 1 and is connected to the top of the inner cavity of the calcining cylinder 2;

[0022] See also Figure 3 and Figure 5 The top of the inner cavity of the feeding hopper 303 is fixedly connected with a connecting frame 302, and the bottom bolt of the electric push rod 301 is installed on the top of the connecting frame 302. By setting the connecting frame 302, it can be fixedly connected to the inner wall of the feeding hopper 303 and meet the fixed installation requirements of the electric push rod 301;

[0023] See also Figure 3 and Figure 5 The top fixing sleeve of the telescopic hose 306 is provided with a fixing sleeve 304, and the small vibration motor 305 is bolted on the fixing sleeve 304. By setting the fixing sleeve 304, it can be connected with the telescopic hose 306 and meet the fixed installation requirements of the small vibration motor 305;

[0025] See also Figure 3 and Figure 5 , the bottom of the feeding hopper 303 is fixedly connected to a vertical rod, and the bottom of the vertical rod is fixedly connected to the top of the fixing frame 1;

[0026] There are three heating calciners 6 , and the calcination temperatures of the three heating calciners 6 are different, so as to form a three-stage calcination, which is more in line with actual use requirements.

[0027] During use, all components are in the initial installation state. First, the electric push rod 301 is controlled to extend and retract, driving the crushing rod 307 to continuously move up and down, while the titanium dioxide material is added through the feeding hopper 303. The moving crushing rod 307 crushes the larger-sized condensed materials. Then, the small vibration motor 305 is controlled to work. Under the connection action of the fixed sleeve 304, the telescopic hose 306 produces elastic deformation, which is more conducive to the falling of the material. Finally, the material is placed in the calcining tube 2. At this time, the reduction motor 4 is controlled to rotate forward to drive the movable rod 9 to rotate, so that the multiple spiral blades 7 rotate synchronously, and the material is continuously transported to the left. The friction between the moving material and the protruding teeth 8 can play a role in assisting crushing. At the same time, the heating calciner 6 is operated to calcine the material in the calcining tube 2 in a graded manner. The reduction motor 4 can also be controlled to reverse and transport the material to the right, achieving circular transportation and ensuring the overall calcining efficiency. After the calcining process is completed, the discharge valve 5 is controlled to open and the reduction motor 4 is controlled to rotate forward. The material will continuously move to the left and be discharged through the discharge valve 5.

[0028] In summary, the titanium dioxide graded calcining device, by providing a crushing processing component 3, spiral blades 7, convex teeth 8 and movable rods 9, solves the problem that the device cannot pre-crush the material, and the larger particles of material enter the interior of the equipment, which easily causes blockage at the feed and delivery points, and has certain limitations.
