Description

Technical Field

[0001] This invention relates to the field of purification technology, specifically to a purification apparatus for the preparation of potassium fluorotitanate. Background Technology

[0002] In the potassium fluorotitanate purification process, traditional spraying and feeding are mostly done in a one-way direct spray mode. The sprayed impurity remover and the raw material solution are not mixed evenly, which can easily lead to local high concentrations or reaction blind zones. Moreover, there is no directional swirling flow to guide the feeding, and the solution is prone to stratification, resulting in insufficient reaction of impurities and large fluctuations in crystal purity. At the same time, the one-way flow field is prone to foam accumulation, requiring additional manual intervention to remove the foam, which not only reduces the purification efficiency but also increases the loss of raw materials, making it difficult to meet the needs of large-scale continuous production.

[0003] Patent CN215026743U discloses a purification device for the preparation of potassium fluorotitanate and potassium fluoroborate, including a support platform and a purification box fixedly installed on the upper surface of the support platform. The purification box has a filter chamber and a purification chamber respectively opened from top to bottom, separated by a partition. A motor housing is fixedly installed in the center of the lower end of the partition, and a motor is fixedly installed inside the motor housing. The motor is connected to a rotating shaft via a motor shaft. Multiple scraper plates are fixedly installed at equal intervals on the outer edge of the rotating shaft. The ends of the scraper plates away from the rotating shaft abut against the inner wall of the purification chamber. Multiple slots are equally spaced on the top of the outer edge of the purification box to connect to the filter chamber. Filter screens are detachably installed in each slot. A pull ring is constructed on the side of the filter screen away from the filter chamber. This purification device for the preparation of potassium fluorotitanate and potassium fluoroborate has a reasonable structure, facilitates cleaning of the inner wall of the device, and makes it easy to disassemble the filter screen, making it highly practical.

[0004] When this device is in use, it is difficult to achieve complete fusion and contact between the potassium fluorotitanate solution and the impurity removal agent during the purification process. This can lead to a decrease in the purification rate of the potassium fluorotitanate solution. At the same time, it is difficult to remove the foam generated during the fusion of the potassium fluorotitanate solution and the impurity removal agent, resulting in a decrease in purification quality and affecting the subsequent purification quality of the potassium fluorotitanate solution. Therefore, a purification device for the preparation of potassium fluorotitanate is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a purification apparatus for the preparation of potassium fluorotitanate, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a purification device for the preparation of potassium fluorotitanate, comprising a support frame, a purification storage tank mounted on the support frame, a feed pipe mounted on the purification storage tank, a motor mounted at the bottom of the feed pipe, a rotating shaft rotatably connected to the inner wall of the purification storage tank, a ring frame fixedly connected to the inner wall of the purification storage tank, a fixing block fixedly connected to the circumferential surface of the rotating shaft, an opening box slidably connected to the top of the fixing block, a diverter pipe fixedly connected to the bottom of the feed pipe, a sealing plate fixedly connected to the circumferential surface of the rotating shaft, and a reciprocating screw rotatably connected to the inner wall of the fixing block. The reciprocating screw has a gear fixedly connected to its circumferential surface, a moving block movably connected to its circumferential surface, a spray head fixedly connected to the inner wall of the moving block, a toothed ring fixedly connected to the inner wall of the purification storage tank, a slider slidably connected to the inner wall of the purification storage tank, a limit post fixedly connected to the top of the slider, and a removal agent tank inside the purification storage tank. This allows the fixed block to accelerate the dripping of the solution inside, disperse the solution, and enable the removal agent in the subsequent spraying device to fully contact and quickly fuse with the solution, accelerating the fusion reaction rate of the removal agent and potassium fluorotitanate solution, and speeding up the separation rate of impurities from the solution.

[0007] Preferably, the circumferential surface of the rotating shaft is provided with a speed-up mechanism for accelerating liquid fusion, and the inner wall of the speed-up mechanism is provided with a protective mechanism for capturing foam. The fixed block is rotatably connected to the inner wall of the ring frame, and the perforated box is fixedly connected to the bottom of the diversion pipe. The diversion pipe is connected to the feed pipe, the diversion pipe is connected to the perforated box, and the perforated box is connected to the fixed block. A liquid guide hole is provided at the bottom of the fixed block, which improves the purification effect and efficiency of the device for potassium fluorotitanate solution. The spray head can spray the impurity removal agent simultaneously, which can increase the contact area between the impurity removal agent and the solution, further improve the fusion reaction rate of the impurity removal agent and the solution, improve the purification speed of potassium fluorotitanate solution, and accelerate the separation of impurities in potassium fluorotitanate solution.

[0008] Preferably, the rotating shaft is fixedly connected to the output end of the motor, the moving block is slidably connected to the circumferential surface of the limiting post, and the limiting post is used to provide motion guidance and limitation for the moving block. The gear meshes with the gear ring, and the gear ring is used to drive the gear to rotate. The spray head is connected to the impurity removal agent tank. The rotation of the fixed block will drive the reciprocating screw to rotate around itself as the rotation center. During the rotation of the reciprocating screw around the fixed block as the rotation center, the rotation of the reciprocating screw will synchronously drive the gear to rotate.

[0009] Preferably, the speed-up mechanism includes a fixed sleeve, which is fixedly connected to the circumferential surface of the rotating shaft. A connecting rod is fixedly connected to the circumferential surface of the fixed sleeve, and an orifice plate is fixedly connected to the circumferential surface of the connecting rod. An elastic telescopic rod is fixedly connected to the front of the orifice plate, and a sealing plate is fixedly connected to the telescopic end of the elastic telescopic rod. A guide inclined plate is rotatably connected to the circumferential surface of the sealing plate via a torsion spring, so that the sealing plate contacts the orifice plate and seals the holes on the surface of the orifice plate. At this time, the mixing speed of the solution can be achieved by rotating the orifice plate forward and backward, and the speed can be dynamically increased according to the amount of potassium fluorotitanate, thereby accelerating the purification speed and quality of the potassium fluorotitanate solution by the device.

[0010] Preferably, the speed-up mechanism further includes a fixed rod, which is fixedly connected to the circumferential surface of the reciprocating lead screw. A fixed column is fixedly connected to the inner wall of the fixed rod, and a scraper is fixedly connected to the circumferential surface of the fixed column. The scraper can clean the residual impurity solution on the inner wall of the purification storage tank, ensuring that the residual impurities and solution on the inner wall of the purification storage tank do not affect the purification operation during the purification of potassium fluorotitanate solution.

[0011] Preferably, the surface of the perforated plate is provided with bubble holes, the scraper is in contact with the purification and storage tank, and the scraper is used to scrape off the residual substances on the inner wall of the purification and storage tank for cleaning. During the rotation of the reciprocating screw, the rotation of the reciprocating screw will drive the fixed rod to rotate, the rotation of the fixed rod will drive the fixed column to rotate, and the rotation of the fixed column will drive the scraper to rotate synchronously.

[0012] Preferably, the protective mechanism includes a second elastic telescopic rod, which is fixedly connected to the inner wall of the fixed block. A filter plate is fixedly connected to the telescopic end of the second elastic telescopic rod. A connector is fixedly connected to the bottom of the perforated box, and a scraper is fixedly connected to the bottom of the connector. This allows the scraper to scrape the surface of the filter plate, improving its service life and preventing the filter plate from becoming clogged with debris due to prolonged use, which would affect the initial treatment of the potassium titanate solution. This enhances the quality and stability of the potassium titanate solution produced by the device.

[0013] Preferably, the protective mechanism further includes a guide slide, which is fixedly connected to the left side of the perforated plate. A float column is slidably connected to the inner wall of the guide slide, and a connecting frame is fixedly connected to the circumferential surface of the float column. A foam trap is fixedly connected to the inner wall of the connecting frame. The foam trap can scrape and collect the foam accumulated above the horizontal plane, which can prevent the foam from carrying impurities, improve product purity, reduce the probability of impurities entering subsequent processes, lay the foundation for improving the purity of the final product, eliminate the obstacle of foam to mass transfer, and ensure that the impurity removal reaction is sufficient.

[0014] Preferably, the scraper second is in contact with the filter plate, and the scraper second is used to scrape off large impurities filtered from the surface of the filter plate. The float column can keep itself above the water surface according to the water level. At this time, during the rotation of the perforated plate, the perforated plate will drive the guide slide to rotate, the rotation of the guide slide will drive the float column to rotate, and the rotation of the float column will drive the connecting frame to rotate.

[0015] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This purification device for potassium fluorotitanate preparation utilizes the coordinated movement of a support frame, purification storage tank, feed pipe, motor, rotating shaft, ring frame, fixed block, perforated box, diverter pipe, sealing plate, reciprocating screw, gear, moving block, spray head, gear ring, slider, and limiting column. This coordinated movement accelerates the dripping of the solution from the fixed block, dispersing the solution and facilitating rapid contact and fusion of the impurity remover with the solution in the subsequent spraying device. This accelerates the fusion reaction between the impurity remover and the potassium fluorotitanate solution, speeding up the separation of impurities from the solution and improving the purification effect and efficiency of the potassium fluorotitanate solution. The spray head simultaneously sprays the impurity remover, increasing the contact area between the impurity remover and the solution, further enhancing the fusion reaction speed, increasing the purification speed of the potassium fluorotitanate solution, and accelerating the separation of impurities from the potassium fluorotitanate solution.

[0016] 2. This potassium fluorotitanate preparation purification device, through the coordinated movement of the fixed sleeve, connecting rod, orifice plate, elastic telescopic rod one, sealing plate two, guide inclined plate, fixed rod, fixed column, and scraper one, allows the sealing plate two to contact the orifice plate and seal the holes on the orifice plate surface. At this time, the mixing speed of the solution can be adjusted by the forward and reverse rotation of the orifice plate, and can be dynamically increased according to the amount of potassium fluorotitanate, thereby accelerating the purification speed and quality of the potassium fluorotitanate solution. The scraper one can clean the residual impurities in the inner wall of the purification storage tank, ensuring that the residual impurities and solution in the inner wall of the purification storage tank do not affect the purification operation during the potassium fluorotitanate solution purification process.

[0017] 3. This purification device for potassium fluorotitanate preparation utilizes the coordinated movement of the elastic telescopic rod II, filter plate, connector, scraper II, guide slide, float column, connecting frame, and foam eliminator. This allows the scraper II to scrape the surface of the filter plate, extending its service life and preventing clogging of the filter pores due to prolonged use, which would affect the initial treatment of the potassium fluorotitanate solution. This improves the quality and stability of the potassium fluorotitanate produced by the device. The foam eliminator scrapes and collects accumulated foam above the horizontal plane, preventing impurities from being carried by the foam, increasing product purity, reducing the probability of impurities entering subsequent processes, laying the foundation for improving the purity of the final product, eliminating the obstacle of foam to mass transfer, and ensuring a complete impurity removal reaction.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-9One embodiment of the present invention is: a purification device for preparing potassium fluorotitanate, comprising a support 1, a purification storage tank 2 mounted on the support 1, a feed pipe 3 mounted on the purification storage tank 2, a motor 4 mounted at the bottom of the feed pipe 3, a rotating shaft 5 rotatably connected to the inner wall of the purification storage tank 2, a ring frame 8 fixedly connected to the inner wall of the purification storage tank 2, a fixing block 9 fixedly connected to the circumferential surface of the rotating shaft 5, an opening box 10 slidably connected to the top of the fixing block 9, and a diversion pipe 11 fixedly connected to the bottom of the feed pipe 3. A sealing plate 12 is fixedly connected to the circumferential surface of shaft 5. A reciprocating screw 13 is rotatably connected to the inner wall of the fixed block 9. A gear 14 is fixedly connected to the circumferential surface of the reciprocating screw 13. A moving block 15 is movably connected to the circumferential surface of the reciprocating screw 13. A spray head 16 is fixedly connected to the inner wall of the moving block 15. A toothed ring 17 is fixedly connected to the inner wall of the purification storage tank 2. A slider 18 is slidably connected to the inner wall of the purification storage tank 2. A limit post 19 is fixedly connected to the top of the slider 18. A purification agent tank is provided inside the purification storage tank 2. When the device is in use, the operator discharges a fixed amount of potassium fluorotitanate solution into the purification storage tank 2 through the feed pipe 3. During the process of the solution entering, the solution is first diverted through the flow diversion pipe 11 of the feed pipe 3. After diversion, the solution reaches the fixed block 9. At this time, the solution flows out through the opening at the bottom of the fixed block 9. At the same time, the motor 4 is started, and the output end of the motor 4 drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the diversion pipe 11 to rotate, and the rotating shaft 5 also drives the fixed block 9 to rotate. During the rotation, the fixed block 9 can slide and rotate at the bottom of the perforated box 10. During the rotation of the fixed block 9, the fixed block 9 will accelerate the dripping of the solution inside, which can disperse the solution and enable it to fully contact and quickly fuse with the impurity removal agent in the subsequent spraying device. This accelerates the fusion reaction rate of the impurity removal agent and the potassium fluorotitanate solution, speeds up the separation rate of impurities from the solution, and improves the purification effect and efficiency of the device for potassium fluorotitanate solution. The circumferential surface of the rotating shaft 5 is provided with a speed-up mechanism 6 for accelerating liquid fusion. The inner wall of the speed-up mechanism 6 is provided with a protective mechanism 7 for capturing foam. The fixed block 9 is rotatably connected to the inner wall of the ring frame 8. The perforated box 10 is fixedly connected to the bottom of the diversion pipe 11. The diversion pipe 11 is connected to the feed pipe 3. The diversion pipe 11 is connected to the perforated box 10. The perforated box 10 is connected to the fixed block 9. The bottom of the fixed block 9 is provided with a liquid guide hole. The rotating shaft 5 is fixedly connected to the output end of the motor 4. The moving block 15 is slidably connected to the circumferential surface of the limiting post 19. The limiting post 19 is used to provide motion guidance and limitation for the moving block 15. The gear 14 meshes with the gear ring 17. The gear ring 17 is used to drive the gear 14 to rotate. The spray head 16 is connected to the impurity removal agent tank. When the device is in use, the rotation of the fixed block 9 causes the reciprocating screw 13 to rotate around itself. This rotation of the reciprocating screw 13 synchronously drives the gear 14 to rotate, which in turn drives the slider 18 to rotate and slide, and simultaneously drives the moving block 15 to rotate. As the gear 14 rotates around the fixed block 9, it engages with the gear ring 17. The gear ring 17, in turn, drives the gear 14 to rotate around itself. This rotation of the gear 14, in turn, drives the reciprocating screw... The rod 13 rotates synchronously, and the rotation of the reciprocating screw 13 will drive the moving block 15 to rotate. However, at this time, the moving block 15 slides on the circumferential surface of the limiting post 19. The limiting post 19 will cause the moving block 15 to move up and down reciprocally through the reciprocating groove opened on the surface of the reciprocating screw 13 during the rotation. The movement of the moving block 15 will drive the spray head 16 to move up and down. During the movement of the spray head 16, the spray head 16 can spray the impurity removal agent synchronously, which can increase the contact area between the impurity removal agent and the solution, further improve the fusion reaction rate of the impurity removal agent and the solution, improve the purification speed of the potassium fluorotitanate solution, and accelerate the separation effect of impurities in the potassium fluorotitanate solution. Overall working principle: The fixed block 9 accelerates the internal solution dripping, disperses the solution, and allows the impurity remover in the subsequent spraying device to fully contact and rapidly fuse with the solution, accelerating the fusion reaction rate of the impurity remover and potassium fluorotitanate solution, speeding up the separation of impurities from the solution, and improving the purification effect and efficiency of the device for potassium fluorotitanate solution. The moving block 15 can only move up and down by reciprocating grooves opened on the surface of the reciprocating screw 13. The movement of the moving block 15 will drive the spray head 16 to move up and down. During the movement of the spray head 16, the spray head 16 can simultaneously spray out the impurity remover, which can increase the contact area between the impurity remover and the solution, further improve the fusion reaction rate of the impurity remover and the solution, improve the purification speed of potassium fluorotitanate solution, and accelerate the separation effect of impurities in potassium fluorotitanate solution.

[0022] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the speed-up mechanism 6 includes a fixed sleeve 601, which is fixedly connected to the circumferential surface of the rotating shaft 5. A connecting rod 602 is fixedly connected to the circumferential surface of the fixed sleeve 601, and a perforated plate 603 is fixedly connected to the circumferential surface of the connecting rod 602. An elastic telescopic rod 604 is fixedly connected to the front part of the perforated plate 603, and a sealing plate 605 is fixedly connected to the telescopic end of the elastic telescopic rod 604. A guide inclined plate 606 is rotatably connected to the circumferential surface of the sealing plate 605 through a torsion spring. When the device is in use, as the rotating shaft 5 rotates clockwise, the rotation of the rotating shaft 5 drives the fixed sleeve 601 to rotate. The rotation of the fixed sleeve 601 drives the connecting rod 602 to rotate, which in turn drives the orifice plate 603 to rotate. The rotation of the orifice plate 603 drives the elastic telescopic rod 604 to rotate, which in turn drives the sealing plate 605 to rotate. The sealing plate 605 then drives the guide inclined plate 606 to rotate. At this time, the rotation of the orifice plate 603 can fully mix the potassium fluorotitanate solution and the impurity removal reagent. The potassium fluorotitanate solution can pass through the holes of the orifice plate 603 during its rotation. During the high-speed rotation of the orifice plate 603, bubbles are generated, allowing the solution and reagent to fully mix. At the same time, when the rotating shaft 5 rotates counterclockwise, it also drives the elastic telescopic rod 604 to rotate. The rotation of the first telescopic rod 604 causes the second sealing plate 605 to rotate, which in turn causes the guide plate 606 to rotate. During the rotation of the guide plate 606, it is subjected to the reverse thrust of the liquid. The guide plate 606 rotates until it is on the same horizontal plane as the second sealing plate 605. At this point, the guide plate 606 and the second sealing plate 605 are jointly subjected to the reverse thrust of the liquid. During the movement of the second sealing plate 605, it comes into contact with the orifice plate 603 and seals the holes on the surface of the orifice plate 603. The mixing speed of the solution can be adjusted by the forward and reverse rotation of the orifice plate 603. The speed can be dynamically increased according to the amount of potassium fluorotitanate, which can accelerate the purification speed and quality of the potassium fluorotitanate solution of the device. The speed-up mechanism 6 also includes a fixed rod 607, which is fixedly connected to the circumferential surface of the reciprocating lead screw 13. A fixed column 608 is fixedly connected to the inner wall of the fixed rod 607, and a scraper 609 is fixedly connected to the circumferential surface of the fixed column 608. The surface of the perforated plate 603 is provided with bubble holes. The scraper 609 contacts the purification and storage tank 2 and is used to scrape off the residual substances on the inner wall of the purification and storage tank 2 for cleaning. When the device is in use, the reciprocating screw 13 rotates, which in turn drives the fixed rod 607 to rotate. The rotation of the fixed rod 607 drives the fixed column 608 to rotate, and the rotation of the fixed column 608 drives the scraper 609 to rotate synchronously. During the rotation of the scraper 609, the scraper 609 can clean the residual impurity solution on the inner wall of the purification storage tank 2, ensuring that the residual impurities and solution on the inner wall of the purification storage tank 2 do not affect the purification operation during the purification of potassium fluorotitanate solution. The protective mechanism 7 includes a second elastic telescopic rod 701, which is fixedly connected to the inner wall of the fixed block 9. A filter plate 702 is fixedly connected to the telescopic end of the second elastic telescopic rod 701. A connector 703 is fixedly connected to the bottom of the perforated box 10, and a scraper 704 is fixedly connected to the bottom of the connector 703. When the device is in use, the rotation of the fixed block 9 will cause the second elastic telescopic rod 701 to rotate, which in turn will cause the filter plate 702 to rotate. During the rotation of the filter plate 702, the perforated box 10 can rotate relative to the top of the fixed block 9. At this time, the rotation of the filter plate 702 will cause it to come into contact with the scraper 704. The scraper 704 can scrape the surface of the filter plate 702, which can improve the service life of the filter plate 702 and prevent the filter plate 702 from being clogged by debris due to long-term use, thus affecting the initial treatment of potassium titanate solution. This can improve the quality and stability of potassium titanate by the device. The protective mechanism 7 also includes a guide slide 705, which is fixedly connected to the left side of the perforated plate 603. A float column 706 is slidably connected to the inner wall of the guide slide 705. A connecting frame 707 is fixedly connected to the circumferential surface of the float column 706. A foam trap 708 is fixedly connected to the inner wall of the connecting frame 707. A scraper 704 contacts the filter plate 702 and is used to scrape off large impurities filtered from the surface of the filter plate 702. When the device is in use, after the potassium titanate preparation solution and the impurity removal agent are mixed, a certain amount of foam will be generated due to chemical reactions and other factors. At this time, the float column 706 can keep itself above the water surface according to the water level. During the rotation of the orifice plate 603, the orifice plate 603 will drive the guide slide 705 to rotate. The rotation of the guide slide 705 will drive the float column 706 to rotate. The rotation of the float column 706 will drive the connecting frame 707 to rotate. The rotation of the connecting frame 707 will drive the foam catching plate 708 to rotate. During the rotation of the foam catching plate 708, it can scrape and collect the foam accumulated above the water surface, which can prevent the foam from carrying impurities, improve product purity, reduce the probability of impurities entering subsequent processes, lay the foundation for improving the purity of the final product, eliminate the obstacle of foam to mass transfer, and ensure that the impurity removal reaction is complete.

[0023] Overall working principle: Sealing plate 605 contacts orifice plate 603 and seals the holes on the surface of orifice plate 603. The mixing speed of the solution can be adjusted by the forward and reverse rotation of orifice plate 603, dynamically increasing the mixing speed based on the amount of potassium fluorotitanate. This accelerates the purification speed and quality of the potassium fluorotitanate solution. Scraper 609 cleans residual impurities from the inner wall of purification storage tank 2, ensuring that residual impurities and solution on the inner wall of purification storage tank 2 do not affect the purification operation. Scraper 70... 4. The ability to scrape the surface of the filter plate 702 can improve the service life of the filter plate 702 and prevent the filter plate 702 from becoming clogged with debris due to long-term use, which would affect the initial treatment of potassium titanate solution. This can improve the quality and stability of potassium titanate in this device. The foam trap 708 can scrape and collect the foam accumulated above the horizontal plane, which can prevent the foam from carrying impurities, improve product purity, reduce the probability of impurities entering subsequent processes, lay the foundation for improving the purity of the final product, eliminate the obstacle of foam to mass transfer, and ensure that the impurity removal reaction is sufficient.
