A titanium dioxide purification and impurity removal device according to claim 2, characterized in that: The intermittent device (6) comprises: A turntable (61) fixedly connected to the top of the column (54); A connecting column (62) rotatably connected to the outer wall of the rotating disk (61) via a pin; A rack (63) rotatably connected to the end of the connecting column (62) via a pin; A gear (64) meshingly connected to the lower side of the rack (63); A vertical plate (65), both ends of which are rotatably connected to the inner wall of the feed pipe (4) via sealed bearings, and the back side of which is fixedly connected to the inner wall of the gear (64); Two grooves (66) are provided and both are opened on the surface of the vertical plate (65); A guide portion (67) is arranged inside the cover body (56); Wherein, the rotating disk (61) is driven by the upright column (54) so ​​that the connecting column (62) drives the rack (63) to move back and forth, thereby causing the gear (64) to drive the vertical disk (65) to rotate, thereby causing the groove (66) to rotate, and intermittent material discharge is performed, and the rack (63) is guided by the guide part (67).

4. The titanium dioxide purification and impurity removal device according to claim 3, characterized in that: The guide portion (67) comprises: A slide groove (671) is formed on the inner wall of the cover body (56); A slider (672) is slidably engaged with the inner wall of the slide groove (671), and the bottom of the slider is fixedly connected to the top of the rack (63); Wherein, the sliding block (672) is driven by the rack (63) to slide in the sliding groove (671) to guide the rack (63).

5. The titanium dioxide purification and impurity removal device according to claim 1, characterized in that: The vibration device (7) comprises: A dustproof shell (72) fixedly connected to the bottom of the filter frame (2) and located outside the vibration motor (71); A connecting block (73) fixedly connected to the outer wall of the filter screen frame (2); A telescopic column (74), two ends of which are respectively fixedly connected to the top of the connecting block (73) and the inner wall of the outer shell (1); A spring (75) installed inside the telescopic column (74); An adsorption portion (76) is arranged inside the housing (1); The filter frame (2) is driven by the vibration motor (71) to move the connection block (73), thereby moving the telescopic column (74), and further causing the spring (75) to undergo elastic deformation, thereby filtering the titanium dioxide powder and adsorbing the iron filings inside the titanium dioxide powder through the adsorption portion (76).

6. The titanium dioxide purification and impurity removal device according to claim 5, characterized in that: The adsorption part (76) comprises: An inclined plate (761) fixedly connected to the inner wall of the outer shell (1); A magnet (762) fixedly connected to the upper side of the inclined plate (761); A sliding door (763) hinged to the front side of the housing (1); The titanium dioxide moves along the inclined plate (761), and at this time, the magnet (762) sucks out the iron filings inside the titanium dioxide. The iron filings can be cleaned by opening the sliding door (763).
