After reduction, the iron in the reduced titanium is oxidized and enters the solution in the rusting liquid. After separating the iron, the titanium-rich material is artificial rutile. The artificial rutile in the rusting slurry is separated from the iron oxide, and after washing, dewatering, drying and screening, the artificial rutile product is obtained.

[0054] The mixing unit 244 comprises a rotating pipe fixedly sleeved at the top of the stirring box 243, a stirring shaft movably sleeved in the inner circle of the rotating pipe and downwardly extending and movably sleeved with the bottom of the stirring box 243, bottom scraping plates fixedly connected at both sides of the bottom of the stirring shaft and slidingly connected with the inner side wall of the bottom of the stirring box 243, side scraping plates fixedly connected at the top of the bottom scraping plates and slidingly connected with the inner side wall of the stirring box 243, a cover fixedly connected with the top partition plate 241 and arranged at the end of the rotating pipe extending out of the top partition plate 241, a gear ring fixedly sleeved with the top outer circle of the rotating pipe and arranged in the cover, a gear one engaged at one side of the gear ring, a rotating shaft fixedly sleeved in the inner circle of the gear one, a motor two connected with the cover and arranged at the top of the rotating shaft, a motor three connected with the top inner side wall of the cover and arranged at the end of the stirring shaft extending out of the top of the rotating pipe, and the top and bottom of the stirring box 243 are penetrated by communicating holes.

[0055] Working principle: different types of raw materials for preparing artificial rutile are put into the feeding assembly 1, the size of the storage space in the material changing mechanism 4 is adjusted according to the type of the raw material by the adjusting mechanism 5, so as to adjust the metering of the mixed raw materials, then the raw materials in the hopper 7 are drawn downwardly into the material changing mechanism 4, and then discharged from the conveying pipe 8 to the mixing assembly 2 for blending and homogenizing operation of the raw materials;

[0056] When adjusting the metering of the raw materials, the driving unit one on the adjusting mechanism 5 is started to drive the push-pull plate 53 to move, then drive the pull rod one 52 to slide along the length direction of the driving shaft 41, then the adjusting plate 51 slides along the length direction of the storage passage 43 to adjust the distance between the adjusting plate 51 and the air permeable plate 44, so as to adjust the storage space of the raw materials on the storage passage 43, and realize the storage conversion operation of the raw materials with different metering;

[0057] When the raw material is replaced, the motor at the end of the driving shaft 41 is started, and then the rotating disc 42 rotates, and the storage channel 43 on the rotating disc 42 rotates to the position directly below the hopper 7. At this time, the raw material in the hopper 7 falls downward into the storage channel 43, and the driven rod 69 on the extraction and pressing mechanism 6 moves along the holding channel two 6104 to the holding channel one 6102 under the rotation of the bearing plate 61. At this time, the driven rod 69 moves along the length direction of the driving shaft 41, and then drives the adapter pipe 48 to slide along the length direction of the guide pipe one 76. Under the action of the screw, the rotating part 65 which is screwed with the rotating pipe 48 rotates. When the rotating part 65 rotates, the adjusting groove on the rotating rod of the rotating part 65 drives the top rod 664 on the pulling part 66 which is in sliding connection with the adjusting groove to move, and then makes the piston plate 661 and the extending plate 662 slide along the length direction of the air extraction cylinder 62. Then the gas inside the storage channel 43 is extracted into the air extraction cylinder 62. At this time, the top rod 644 seals the adjusting groove when it moves, the piston plate 661 seals the air extraction cylinder 62, and the extending plate 662 seals the sealing shell 64. When the gas inside the storage channel 43 is extracted into the air extraction cylinder 62, the raw material in the hopper 7 is adsorbed downward under the action of negative pressure while the gas is extracted, so that the adsorbed raw material is completely filled into the storage channel 43. At the same time, the gap between the powdery raw material in the storage channel 43 becomes smaller during the adsorption process, and the filling is compact.

[0058] After that, with the rotation of the motor, the storage channel 43 filled with raw material rotates with the rotating disc 42 to the position of the conveying pipe 8. At this time, the above-mentioned reverse steps are installed, and the air extraction cylinder 62 pushes the gas inside it into the storage channel 43 when discharging, so that the raw material quickly enters the conveying pipe 8 downward.

[0059] When the metered raw material enters the mixing box 22 through the mixing pipe 21, the raw material enters the mixing mechanism 24 under the action of the guide mechanism 22. At this time, the motor two in the shell is started to drive the rotating pipe to rotate, and then make the whole stirring box 243 rotate. When the whole stirring box 243 rotates, the communication hole at the top of the stirring box 243 does not communicate with the conveying channel one on the top partition plate 241, so that the material on the top of the top partition plate 241 does not fall downward into the stirring box 243. After that, the motor three is started to rotate the stirring shaft to stir, mix and homogenize the raw material in the stirring box 243. When the stirring is completed, the motor two is started again to make the whole stirring box 243 rotate. At this time, the communication hole at the bottom of the stirring box 243 communicates with the conveying channel two on the bottom partition plate 242, and the mixed raw material enters the lower guide mechanism 23 downward. After that, the above-mentioned way is installed to sequentially mix, stir and homogenize the raw material metered by the feeding assembly 1.

[0060] The design can accurately measure different types of powder raw materials of artificial rutile according to the preparation needs, the negative pressure air exhaust method is used in the measurement process to exhaust the gas in the measured powder raw materials, the measured powder raw materials are closely contacted, the inaccurate measurement caused by the existence of large gaps in the powder raw materials during the measurement process is avoided, the measurement of the powder raw materials is adjusted, the traditional weighing measurement operation is changed, the continuous production is facilitated, the powder raw materials can be mixed and homogenized for multiple times after the measurement, the mixing and homogenizing efficiency and quality of the powder raw materials are improved, the stability of the raw material supply in the preparation process of the artificial rutile is improved, and the quality of the artificial rutile preparation is improved.

[0061] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the protection scope of the present application. Any non-essential changes and replacements made by those skilled in the art on the basis of the present application shall fall within the protection scope of the present application.
