Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a zirconium-hafnium solution crystallization and separation device. Background Technology

[0002] Due to the characteristics of the production process, zirconium-hafnium solution crystals contain a significant amount of impurities, which need to be removed by a separation device. Existing separation devices use centrifugal force to expel the useful components, while retaining the useless impurities inside the filter cartridge.

[0003] For example, CN 118681300 A discloses a process and equipment for separating zirconium-hafnium solution crystallization, which includes a tank, a bottom loading mechanism, a holding mechanism, and a separation mechanism. A side groove is provided on the side wall of the tank, and a first screw is installed in the side groove. A first motor is connected to the upper end of the first screw. A bottom loading mechanism for disassembling and assembling the separation components is provided on the outer wall of the first screw. A holding tank is installed between the bottom loading mechanisms. This equipment is suitable for separating different types of impurities from zirconium-hafnium solution crystallization. The corresponding separation cylinder is selected according to the type of impurities to be separated. After the zirconium-hafnium solution crystallization is poured into the separation cylinder, the third motor is controlled to rotate the connecting plate, which drives the zirconium-hafnium solution crystallization to flow out through the separation cylinder under centrifugal effect, leaving the impurities to be separated, thus achieving separation. However, the following problems still exist: different types of impurities are reflected in different particle sizes, and changing the separation cylinder before separation is relatively troublesome, which is not conducive to improving production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a zirconium-hafnium solution crystallization separation device with a reasonable structure and reliable operation, which solves the problem that existing separation devices require changing the separation cylinder for impurities of different particle sizes, and significantly improves separation efficiency while ensuring separation effect.

[0005] The technical solution of this utility model is:

[0006] A zirconium-hafnium solution crystallization separation device includes a vertical separation tank and a separation cylinder. The key technical features are: an annular pressure cap is fixed to the top of the vertical separation tank; a supporting bearing is fixed to the center of the bottom surface of the vertical separation tank; a horizontal support plate is fixed to the upper end of the inner ring of the supporting bearing; the separation cylinder is fixed above the horizontal support plate; a top cover is fixed to the upper end of the separation cylinder; a wear-resistant ring is provided on the upper surface edge of the top cover, contacting the bottom surface of the annular pressure cap; a motor is supported above the annular pressure cap; a linkage shaft connected to the motor is located at the center of the top cover; and a coupling shaft is provided inside the separation cylinder. The filter sleeve is attached to the inner wall of the filter sleeve, which is provided with an inner filter hole group. The separator cylinder is provided with an outer filter hole group corresponding to the inner filter hole group. The top cover is provided with a rotating handwheel. The lower end of the rotating handwheel's axle passes through the top cover and fixes the driving gear. The upper inner side of the filter sleeve is fixed with a driven gear ring that meshes with the driving gear. The top cover is provided with a bracket and a horizontal screw is provided on the top of the bracket. The tip of the horizontal screw points to the center line of the rotating handwheel. The outer circumference of the rotating handwheel is evenly provided with a plurality of radial holes for cooperating with the tip of the horizontal screw.

[0007] In the aforementioned zirconium-hafnium solution crystallization separation equipment, the bottom of the separation cylinder is provided with a hollow discharge chamber. The upper surface of the hollow discharge chamber is inclined, and the lower end of the inclined surface is provided with a discharge inlet connecting the hollow discharge chamber and the filter inner sleeve. The side wall of the hollow discharge chamber is provided with a pull plate for blocking the discharge inlet. A connecting piece is fixed to the outer end of the pull plate. An electric push rod is also fixed to the side wall of the hollow discharge chamber. The telescopic rod end of the electric push rod is fixed to the connecting piece. The pull plate and the electric push rod are located on the same side of the connecting piece. A slag discharge valve is provided at the lower part of the hollow discharge chamber.

[0008] In the aforementioned zirconium-hafnium solution crystallization and separation equipment, a transparent viewing window is provided on the upper part of the side wall of the vertical separation box.

[0009] In the aforementioned zirconium-hafnium solution crystallization and separation equipment, the lower end of the side wall of the vertical separation tank is provided with a drain port.

[0010] The zirconium-hafnium solution crystallization and separation equipment described above has a feed inlet on the top cover, and a protective cover is provided at the feed inlet.

[0011] In the aforementioned zirconium-hafnium solution crystallization separation equipment, the inner bottom surface of the separation cylinder is provided with an annular guide groove corresponding to the lower end of the filter inner sleeve.

[0012] The beneficial effects of this utility model are:

[0013] 1. Before use, to match the product's separation and filtration requirements, rotate the handwheel. This uses the drive gear to rotate the driven gear ring and the inner filter sleeve, causing the inner and outer filter hole groups to be completely opposite or offset by a certain distance. This changes the actual flow aperture, ensuring separation speed while simultaneously intercepting impurities. Compared to existing technologies, this eliminates the need to replace the separation cylinder, solving the problem of existing separation equipment requiring cylinder replacement for impurities of different sizes. It significantly improves separation efficiency while maintaining the desired separation effect.

[0014] 2. When it is necessary to remove impurities from the filter inner sleeve, first add cleaning water to the separator cylinder, then use the electric push rod to push the connecting plate and drive the pull plate away from the discharge inlet, allowing the cleaning water to carry the impurities into the hollow discharge chamber, and then discharge them through the slag discharge valve into the vertical separator box, and finally discharge them through the liquid discharge port, thus achieving cleaning. Compared with the existing technology, it is not necessary to disassemble the separator cylinder, further improving production efficiency.

[0015] 3. The transparent window allows for observation of the interlacing, separation, and cleaning of the inner and outer filter groups, facilitating operation by staff. Attached Figure Description

[0020] The present invention will be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-3 As shown, the zirconium-hafnium solution crystallization separation device includes a vertical separation tank 6 and a separation cylinder 8.

[0022] The vertical separation box 6 has an annular pressure cover 1 fixed to its top, a support bearing 11 fixed to the center of its bottom surface, a horizontal support plate 12 fixed to the upper end of the inner ring of the support bearing 11, a separation cylinder 8 fixed above the horizontal support plate 12, and a top cover 17 fixed to the upper end of the separation cylinder 8. The upper surface edge of the top cover 17 has a wear-resistant ring 2 that contacts the bottom surface of the annular pressure cover 1. A motor 5 is supported above the annular pressure cover 1, and a linkage shaft connected to the motor 5 is located at the center of the top cover 17.

[0023] The separator 8 has an inner filter sleeve 9 attached to its inner wall. The inner bottom surface of the separator 8 has an annular guide groove 29 corresponding to the lower end of the inner filter sleeve 9. The inner filter sleeve 9 has an inner filter hole group 19, and the separator 8 has an outer filter hole group 18 corresponding to the inner filter hole group 19. The top cover 17 has a rotating handwheel 22. The lower end of the rotating handwheel 22's axle passes through the top cover 17 and is fixed to a drive gear 24. The upper inner surface of the inner filter sleeve 9 is fixed with a driven gear ring 16 that meshes with the drive gear 24. The top cover 17 has a bracket 21, and the top of the bracket 21 has a horizontal screw 20. The tip of the horizontal screw 20 points to the center line of the rotating handwheel 22. The outer circumference of the rotating handwheel 22 has a plurality of radial holes 23 evenly distributed for engaging with the tip of the horizontal screw 20.

[0024] In this embodiment, the bottom of the separating cylinder 8 is provided with a hollow discharge chamber 14. The upper surface of the hollow discharge chamber 14 is an inclined surface 13, and the lower end of the inclined surface 13 is provided with a discharge inlet 25 connecting the hollow discharge chamber 14 and the filter inner sleeve 9. A pull-out plate 26 for sealing the discharge inlet 25 is provided on the side wall of the hollow discharge chamber 14. A connecting piece 27 is fixed to the outer end of the pull-out plate 26. An electric push rod 28 is also fixed to the side wall of the hollow discharge chamber 14. The telescopic end of the electric push rod 28 is fixed to the connecting piece 27. The pull-out plate 26 and the electric push rod 28 are located on the same side of the connecting piece 27. A slag discharge valve 15 is provided at the lower part of the hollow discharge chamber 14.

[0025] The vertical separation box 6 has a transparent viewing window 7 on the upper part of its side wall. The vertical separation box 6 has a drain port 10 at the lower end of its side wall. The top cover 17 has a feed inlet 4, and the feed inlet 4 is covered with a protective cover 3.

[0026] Working principle:

[0027] 1. Before operation, to match the product's separation and filtration requirements, rotate the handwheel 22. This uses the drive gear 24 to drive the driven gear ring 16 and the inner filter sleeve 9 to rotate, making the inner filter hole group 19 and the outer filter hole group 18 completely opposite or offset by a certain distance, thereby adjusting the actual flow orifice diameter. Then, rotate the horizontal screw 20 so that the tip of the horizontal screw 20 is inserted into the radial hole 23 on the outer circumference of the handwheel 22 for positioning. There are many radial holes 23 to meet the positioning requirements.

[0028] 2. Open the cover 3 and feed the material through the feed port 4 on the top cover 17, then close the cover 3. Start the motor 5 to drive the separation cylinder 8 to rotate. Under the action of centrifugal force, the material enters the vertical separation box 6 through the flow channel formed by the inner filter hole group 19 and the outer filter hole group 18, and is then discharged through the drain port 10. The impurities are trapped in the inner filter sleeve 9, thus achieving separation.

[0029] 3. When it is necessary to clean impurities, first add cleaning water to the separator 8 through the feed inlet 4, then cover it with the protective cover 3. The motor 5 drives the separator 8 to rotate and clean for a period of time before stopping. Then start the electric push rod 28 to push the connecting plate 27 away and drive the pull plate 26 to disengage from the discharge inlet 25, so that the cleaning water carries the impurities into the hollow discharge chamber 14, and then discharges them into the vertical separator 6 through the slag discharge valve 15, and finally discharges them through the liquid discharge port 10, thus achieving cleaning.

[0030] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
