Utility Model Content

[0004] The purpose of this invention is to provide a zirconium-based material defluorination device to address the issues in the background technology where defluorination devices still require further improvement in terms of defluorination efficiency and regeneration convenience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a zirconium-based material defluorination device, including a reaction vessel, a sealing cap threaded to the top of the reaction vessel, and a defluorination assembly installed inside the reaction vessel;

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, by setting a symmetrical zirconium-based material filling layer, zirconium dioxide utilizes its excellent fluoride ion adsorption performance to significantly improve the fluoride ion removal efficiency. At the same time, the design of the stirring component ensures that the liquid to be treated is in full contact with the zirconium-based material, avoiding excessively high local concentrations that could affect the adsorption effect, and further ensuring the thoroughness of fluoride removal.

[0016] The adjustable design allows for flexible changes in the extension lengths of the first and second stirring rods to adapt to different liquid levels and reaction requirements. Rotating the sleeve drives the gears, and through the meshing of the gears with the tooth grooves, the first and second stirring rods slide horizontally, satisfying diverse stirring range requirements and enabling the cleaning of the zirconium-based material filling layer surface.

[0018] 3. In this utility model, the filter element is set before the liquid enters the reaction vessel to perform preliminary filtration, remove larger impurities, and prevent impurities from affecting the adsorption performance of zirconium-based materials and the normal operation of internal components of the equipment; the presence of the buffer pad reduces vibration and impact during liquid inlet, and enhances the stability of the equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example; please refer to Figure 1 - Figure 4 The diagram shows a zirconium-based material defluorination device, which includes a reaction vessel 1, a cap 2 threadedly connected to the top of the reaction vessel 1, and a drain outlet 5 on the reaction vessel 1. After the defluorination process is completed, the treated liquid is discharged through the drain outlet 5 on the reaction vessel 1, and the fluoride content of the discharged water needs to be tested. A defluorination component 3 is installed inside the reaction vessel 1.

[0026] The defluorination assembly 3 includes symmetrically and detachably installed zirconium-based material filling layers 31 on both sides of the reactor 1. The zirconium-based material filling layers 31 penetrate the reactor 1 and are inserted into it. The zirconium-based material filling layer 31 is zirconium dioxide, an oxide of zirconium. Zirconium dioxide removes fluoride ions from the liquid through adsorption, achieving the purpose of defluorination. When fluoride-containing water flows through this filling layer, fluoride ions are adsorbed onto the active sites on the surface or inside of the zirconium-based material through physical adsorption, chemical adsorption, and other mechanisms, thereby achieving the removal of fluoride ions from the water. When adsorption reaches saturation... Afterwards, the above-mentioned regeneration process is required to restore its adsorption capacity so that it can continue to carry out defluorination work. The zirconium-based material filling layer 31 is symmetrically fixed with mounting blocks 32 on both sides. The reactor 1 is provided with a mounting groove 34 for the mounting blocks 32 to be inserted. The mounting blocks 32 are threaded with bolts 33 and the bolts 33 are threaded into the mounting groove 34. When it is necessary to replace or maintain the zirconium-based material filling layer 31, the bolts 33 are unscrewed and the mounting blocks 32 are taken out from the mounting groove 34. The regeneration liquid is then evenly sprayed onto the zirconium-based material filling layer 31.

[0027] A motor 35 is detachably mounted on the cover 2. The motor 35 is rotatably connected to a rotating shaft 36 via a coupling. An adjusting component 37 is provided on the rotating shaft 36. The adjusting component 37 includes a cavity 376 formed on the rotating shaft 36. A gear 377 is rotatably connected inside the cavity 376. A rotating sleeve 371 is fixedly mounted on the gear 377. The rotating sleeve 371 passes through the rotating shaft 36 and is located outside the rotating shaft 36. A first stirring rod 372 and a second stirring rod 374 with identical structures are horizontally slidably connected on the rotating shaft 36. Both the first stirring rod 372 and the second stirring rod 374 have tooth grooves 378 adapted to the gear 377. The ends of the first stirring rod 372 and the second stirring rod 374 are... Both the first stirring rod 372 and the second stirring rod 374 are connected by threaded caps 379. Fixing plates 373 are fixedly installed at the ends of both the first stirring rod 372 and the second stirring rod 374. An adhesive layer 3731 is provided on the fixing plate 373, and a cleaning brush 3732 is bonded to the adhesive layer 3731. The cleaning brush 3732 is bonded to the fixing plate 373 through the adhesive layer 3731. Then, the positions of the first stirring rod 372 and the second stirring rod 374 are adjusted by the adjusting component 37 so that the cleaning brush 3732 contacts the surface of the zirconium-based material filling layer 31. The zirconium-based material filling layer 31 is rinsed with clean water, and the cleaning brush 3732 removes residual regeneration liquid and impurities, preparing for the next defluorination operation.

[0028] A filter element 4 is detachably installed on the cover 2;

[0029] The filter element 4 includes a through hole 41 on the cover 2, an inlet pipe 42 inserted into the through hole 41, a retaining ring 422 detachably installed on the inlet pipe 42, a buffer pad 421 bonded inside the retaining ring 422, and a fastening screw 423 detachably installed at the end of the retaining ring 422. The inlet pipe 42 passes through the cover 2 and is threadedly connected to a filter sleeve 424. The filter sleeve 424 has several sets of filter holes 425, and a threaded groove 426 for threaded connection of the inlet pipe 42 is provided on the top of the filter sleeve 424. A fixing plate 373 is located at the bottom of the filter sleeve 424 to prevent the fixing plate 373 from impacting the filter sleeve 424 when the first stirring rod 372 and the second stirring rod 374 rotate with the rotating shaft 36.

[0030] Working principle:

[0031] The fluorine-containing liquid to be treated enters the equipment through the inlet pipe 42. It is first filtered by the filter sleeve 424. The filter holes 425 on the filter sleeve 424 intercept larger impurities in the liquid. The preliminarily purified liquid enters the reaction vessel 1. When the inlet pipe 42 rotates in the threaded groove 426, the filter sleeve 424 can be disassembled.

[0032] The motor 35 is started, which drives the rotating shaft 36 to rotate. The first stirring rod 372 and the second stirring rod 374 on the rotating shaft 36 rotate with the rotating shaft 36 to stir the liquid in the reactor 1. According to actual needs, the rotating sleeve 371 can be rotated. The rotating sleeve 371 drives the gear 377 to rotate in the cavity 376. The gear 377 meshes with the tooth groove 378 on the first stirring rod 372 and the second stirring rod 374, so that the first stirring rod 372 and the second stirring rod 374 slide in the horizontal direction to adjust the stirring range and ensure that the liquid is in full contact with the zirconium-based material filling layer 31 on both sides for defluorination.

[0033] The zirconium-based material filling layer 31 uses zirconium dioxide to remove fluoride ions from the liquid through adsorption, thus achieving the purpose of defluorination. When fluoride-containing water flows through this filling layer, fluoride ions are adsorbed on the active sites on the surface or inside of the zirconium-based material through physical adsorption, chemical adsorption, and other mechanisms, thereby achieving the removal of fluoride ions from the water. When the adsorption reaches saturation, the above-mentioned regeneration process is required to restore its adsorption capacity so that defluorination can be carried out continuously.

[0034] When it is necessary to replace or maintain the zirconium-based material filling layer 31, simply unscrew the bolt 33 and remove the mounting block 32 from the mounting groove 34. Spray the regeneration solution evenly onto the zirconium-based material filling layer 31. The regeneration solution reacts with the fluoride ions adsorbed on the zirconium-based material, restoring the adsorption capacity of the zirconium-based material. The regeneration solution is a sodium hydroxide solution. By utilizing the competitive adsorption between hydroxide ions and fluoride ions, as well as the interaction with the zirconium-based material, the fluoride ions adsorbed on the zirconium-based material are desorbed into the solution, thereby restoring the adsorption sites of the zirconium-based material and allowing it to regain the ability to adsorb fluoride ions. Adhere the cleaning brush 3732 to the fixing plate 373 through the adhesive layer 3731, and then adjust the position of the first stirring rod 372 and the second stirring rod 374 through the adjusting component 37 so that the cleaning brush 3732 contacts the surface of the zirconium-based material filling layer 31. Rinse the zirconium-based material filling layer 31 with clean water, and use the cleaning brush 3732 to remove residual regeneration solution and impurities, preparing for the next defluorination operation.

[0035] After the defluorination process is completed, the treated liquid is discharged through the drain port 5 on the reactor 1.
