Description

Technical Field

[0001] The utility model relates to the technical field of titanium dioxide filtration, in particular to a titanium dioxide turbid liquid filtration device. Background Technique

[0002] Titanium dioxide is an inorganic compound and an indispensable material in industrial applications. In the process of polyester production, titanium dioxide is used as a raw material to be mixed with other additives. In order to ensure the purity of titanium dioxide, usually before mixing, the turbid liquid of titanium dioxide is filtered to filter out impurities or fine particles in the titanium dioxide.

[0003] However, when the existing titanium dioxide turbid liquid filtration device is in use, the turbid liquid is usually directly introduced into the filtration device for filtration. Since the chemical bond of titanium dioxide is not stable enough, it is easy to agglomerate into large particles of colloid in the turbid liquid, so that the impurities in the turbid liquid are simultaneously wrapped in the colloid, which is not conducive to filtering out the impurities in the turbid liquid, resulting in poor filtration effect of the turbid liquid; in addition, due to the strong adhesion of titanium dioxide particles, when the titanium dioxide particles in the filtered turbid liquid flow in the device, they are easy to form residues on the inner wall of the device, resulting in a time-consuming subsequent cleaning process inside the filtration device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a titanium dioxide turbid liquid filtration device to solve the problems put forward in the above background technique.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In this titanium dioxide turbid liquid filtering device, through the conical cylinder, the nozzle, the annular pipe and the scraping strip, the colloid in the titanium dioxide turbid liquid can be dispersed by the water flow ejected from the nozzle to form particles with smaller particle sizes, and then the scraping strip scrapes along the top of the filter screen to spread the dispersed colloid on the filter screen, so that the impurities wrapped in the colloid can be peeled off from the colloid, which is beneficial to filtering out the impurities in the titanium dioxide turbid liquid and improving the filtering effect of the titanium dioxide turbid liquid.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0023] As Figures 1 to 4 shown, the titanium dioxide turbid liquid filtering device of this embodiment includes a tank body 4. The middle part of the top end of the tank body 4 is penetrated by a feed pipe 1. The outside of the feed pipe 1 is provided with an annular pipe 2. One side of the outer wall of the annular pipe 2 is penetrated by a water inlet pipe 3. The bottom end of the annular pipe 2 is fixedly installed with a plurality of nozzles 8. A conical cylinder 9 is arranged inside the tank body 4. A rotating motor 10 is fixedly installed inside the conical cylinder 9. The output end of the rotating motor 10 is engaged with a rotating shaft 11. A plurality of scraping strips 12 are engaged in the middle of the rotating shaft 11. Two scrapers 15 are engaged at the bottom of the rotating shaft 11. A filter screen 13 is engaged in the middle of the inner side of the tank body 4. One side of the outer wall of the tank body 4 is penetrated by an impurity discharge hopper 5. The bottom of the tank body 4 is fixedly connected with support legs 6. The middle part of the bottom end of the tank body 4 is penetrated by a discharge pipe 7.

[0024] Specifically, both the top and bottom ends of the tank body 4 are in the shape of a "frustum of a cone", enabling the titanium dioxide suspension to flow into and out of the tank body 4 quickly and not easily forming residues. The pipe orifice at the bottom end of the feed pipe 1 is located directly above the top end of the conical cylinder 9, allowing the titanium dioxide suspension input from the feed pipe 1 to directly fall on the outer wall of the conical cylinder 9 and flow along the outer wall of the conical cylinder 9 towards the filter screen 13, dispersing the sediment colloids in the titanium dioxide suspension. The water inlet pipe 3 can continuously introduce high-pressure water flow into the annular pipe 2, enabling the water flow ejected by the nozzle 8 to impact the titanium dioxide suspension flowing along the surface of the conical cylinder 9, so that the colloids in the titanium dioxide suspension can be dispersed, facilitating the exposure of the impurities in the titanium dioxide suspension from the wrapped colloids and being more conducive to the screening of impurities. The water ejection orifice of the nozzle 8 surrounds the top of the conical cylinder 9 and faces the surface of the top of the conical cylinder 9, enabling the ejected water flow to effectively impact the titanium dioxide suspension on the surface of the conical cylinder 9, thus facilitating the dispersion of the titanium dioxide suspension. The cross-section of the conical cylinder 9 is "triangular" and its outer surface is smooth, making it difficult for the titanium dioxide suspension flowing downward along the surface of the conical cylinder 9 to adhere to the conical cylinder 9. The rotating shaft 11 can drive the scraping strip 12 and the scraping plate 15 to rotate simultaneously, realizing the scraping of the filter screen 13 by the scraping strip 12 and the scraping of the inner wall of the tank body 4 by the scraping plate 15. The scraping strip 12 can further spread the dispersed colloid particles on the filter screen 13, enabling the impurities wrapped in the colloid to be separated from the titanium dioxide colloid, thus realizing the screening of impurities. At the same time, the screened impurities can be pushed towards the impurity discharge hopper 5, enabling the impurities to be quickly separated from the filter screen 13 and improving the filtering speed of the filter screen 13. The filter screen 13 can filter the impurities in the colloid. The scraping plate 15 can scrape along the inner wall of the tank body 4, enabling the titanium dioxide particles adhering to the inner wall of the tank body 4 to be quickly discharged from the discharge pipe 7 along with the filtered suspension, reducing the residue of titanium dioxide particles on the inner wall of the device.

[0025] Furthermore, the annular pipe 2 is fixedly installed at the top end of the tank body 4. The nozzle 8 is located inside the tank body 4. The nozzle 8 is internally connected to the annular pipe 2 and the water inlet pipe 3. The nozzle 8 can direct the high-pressure water flow introduced through the annular pipe 2 towards the surface of the conical cylinder 9, dispersing the titanium dioxide suspension flowing along the surface of the conical cylinder 9, thus facilitating the breakup of the colloid precipitation in the titanium dioxide suspension and being more conducive to the filtering out of impurities in the colloid.

[0026] Furthermore, a through hole 17 is provided at the bottom end of the impurity discharge hopper 5. A screen is clamped at the top of the through hole 17. The through hole 17 enables the solution entering the impurity discharge hopper 5 to enter the return pipe 14, thus preventing the solution in the device from flowing out through the opening of the impurity discharge hopper 5.

[0027] Furthermore, a reflux pipe 14 is sleeved at the bottom end of the through hole 17. The bottom end of the reflux pipe 14 penetrates through the bottom of the tank body 4. The reflux pipe 14 enables the aqueous solution entering the impurity discharge hopper 5 to flow back into the device, thereby avoiding unnecessary waste of the titanium dioxide turbid liquid.

[0028] Furthermore, connecting plates 16 are fixedly connected to both sides of the top of the conical cylinder 9. The connecting plates 16 are fixedly connected to the inner wall of the tank body 4. The conical cylinder 9 is fixedly connected to the tank body 4 through the connecting plates 16. The connecting plates 16 enable the conical cylinder 9 to be fixed directly below the feed pipe 1, so that the titanium dioxide turbid liquid flowing in from the feed pipe 1 can smoothly flow onto the surface of the conical cylinder 9.

[0029] Furthermore, the rotating shaft 11 is movably penetrated and connected with the filter screen 13. The scraping strip 12 is movably connected with the filter screen 13 through the rotating shaft 11. The scraping plate 15 is movably connected with the tank body 4 through the rotating shaft 11. When the scraping strip 12 scrapes along the top of the filter screen 13, the colloid precipitate falling on the filter screen 13 can be scraped open, so that the impurities wrapped in the colloid are precipitated, which is beneficial to the filtration of the impurities by the filter screen 13 and improves the filtration effect of the titanium dioxide turbid liquid.

[0030] Furthermore, an opening is provided at the junction of the impurity discharge hopper 5 and the tank body 4. The impurity discharge hopper 5 communicates with the inside of the tank body 4 through the opening. The bottom of the impurity discharge hopper 5 is at the same horizontal height as the top of the filter screen 13, so that the impurities intercepted on the filter screen 13 can be pushed into the impurity discharge hopper 5 by the rotating scraping strip 12 and then quickly discharged from the impurity discharge hopper 5, thereby reducing the impurities accumulated on the filter screen 13 and being beneficial to improving the filtration efficiency of the filter screen 13.

[0031] The usage method of this embodiment is as follows: Before using this titanium dioxide turbid liquid filtering device, it is necessary to first connect the device to an external power supply, and then introduce the titanium dioxide turbid liquid into the feed pipe 1, while pumping high-pressure water flow into the water inlet pipe 3. At this time, the titanium dioxide turbid liquid will flow from the nozzle at the bottom end of the feed pipe 1 to the top of the conical cylinder 9, and then flow along the surface of the conical cylinder 9 to the filter screen 13. At the same time, the high-pressure water flow in the water inlet pipe 3 will enter the annular pipe 2, then enter the nozzle 8 along the annular pipe 2, and then form a high-pressure water column from the nozzle 8 and rush towards the surface of the conical cylinder 9, so that the titanium dioxide turbid liquid flowing along the surface of the conical cylinder 9 is diluted and dispersed. At the same time, the colloid precipitate in the titanium dioxide turbid liquid will also be dispersed and then fall on the filter screen 13. Then, start the rotary motor 10, so that the rotary motor 10 drives the rotation shaft 11 to rotate, driving the scraping strip 12 in the middle of the rotation shaft 11 and the scraping plate 15 at the bottom to scrape along the top of the filter screen 13 and the inner wall of the bottom of the tank body 4 respectively, so that the colloid precipitate in the titanium dioxide turbid liquid falling on the filter screen 13 is further spread out, so that the impurities wrapped in the colloid are exposed and intercepted by the filter screen 13. The titanium dioxide particles formed after the colloid is dispersed will pass through the filter screen 13, and then flow along the inner wall of the tank body 4 to the discharge pipe 7. The impurities intercepted on the filter screen 13 will slide towards the impurity discharge hopper 5 with the push of the scraping strip 12, and then be discharged from the opening of the impurity discharge hopper 5. At the same time, the bottom of the impurity discharge hopper 5 can send the titanium dioxide turbid liquid and titanium dioxide particles that have mistakenly entered the impurity discharge hopper 5 back into the tank body 4 through the return pipe 14, and finally be discharged from the tank body 4 together with the filtered titanium dioxide turbid liquid from the discharge pipe 7.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
