Description

Technical Field

[0001] This utility model relates to the field of potassium fluorozirconate preparation technology, specifically a potassium fluorozirconate synthesis apparatus. Background Technology

[0002] In the production process of potassium fluorozirconate, fluorozirconic acid solution and potassium chloride solution need to be fully reacted under normal temperature and pressure conditions to obtain potassium fluorozirconate crystals, which are usually synthesized in a reaction vessel.

[0003] An investigation revealed a novel potassium fluorozirconate synthesis tank (Publication No.: CN218189184U) disclosed in a Chinese utility model patent. The tank includes a synthesis body with support legs fixedly connected to both sides of its bottom. A stirring shaft is movably connected to the bottom of the synthesis body. Two sets of second stirring blades are fixedly connected to the bottom of both sides of the stirring shaft. Six stirring rods are fixedly connected to the outside of the stirring shaft, with first and third stirring blades fixedly connected to the outside of each stirring rod. A feed inlet is fixedly connected to the top of the synthesis body. This novel potassium fluorozirconate synthesis tank uses a drive motor to rotate the stirring shaft. The first and third stirring blades outside the stirring shaft can thoroughly mix the materials, improving synthesis efficiency. The second stirring blades not only improve mixing efficiency but also facilitate stirring of materials settling at the bottom. This structure improves the efficiency of potassium fluorozirconate synthesis through multi-directional stirring, solving the problem of low synthesis efficiency.

[0004] Although the aforementioned patent achieves multi-directional stirring of potassium fluorozirconate through the setting of multiple sets of stirring blades, the stirring rod, stirring shaft and stirring blades are fixedly connected, so the stirring trajectory always remains in a single mode. The single stirring trajectory cannot flexibly adjust the stirring intensity and range according to the reaction process of the material. When the potassium fluorozirconate reaction enters the middle and late stages and the viscosity of the material increases, the fixed blades are difficult to form an effective shearing and diffusion effect, resulting in a slowdown in the mixing speed of the material and a prolongation of the reaction cycle.

[0005] Therefore, this invention provides a potassium fluorozirconate synthesis apparatus to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a potassium fluorozirconate synthesis apparatus, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a potassium fluorozirconate synthesis apparatus, comprising a reaction vessel, and further comprising:

[0010] A stirring assembly, which is installed on the reactor, is used to stir the potassium fluorozirconate raw material;

[0011] The stirring assembly includes a drive motor fixed to the top of the reactor. The output shaft of the drive motor is fixed to a stirring shaft via a coupling. A fixed shaft is fixed to the bottom of the reactor cavity. The stirring shaft is sleeved on the outer surface of the fixed shaft. Two sets of first bevel gears are fixed to the outer surface of the fixed shaft. Several sets of fixed columns are fixed to the outer surface of the stirring shaft. A stirring rod is rotatably connected to the inside of the fixed columns with bearings. One end of the stirring rod extends into the interior of the stirring shaft and is fixed with a second bevel gear. Several sets of stirring blades are fixed to the outer surface of the stirring rod.

[0012] As a preferred technical solution of this application, the stirring shaft has a cavity inside, a return spring and a movable part are sleeved on the inner side of the cavity, and several sets of movable frames are sleeved on the outer side of the stirring shaft. One end of the movable frame extends into the cavity and is fixed with a connecting plate, and the other end of the movable frame is fixed with a scraper.

[0013] As a preferred technical solution of this application, a sealing ring is embedded inside the fixed column, and the sealing ring covers the outer surface of the stirring rod.

[0014] As a preferred technical solution of this application, the second bevel gear is meshed with the first bevel gear.

[0015] As a preferred technical solution of this application, the bottom end of the movable part is tapered, and the movable part is in contact with the connecting plate by compression.

[0016] As a preferred technical solution of this application, the reset spring is elastically supported between the cavity and the moving part.

[0017] As a preferred technical solution of this application, the scraper is in contact with the inner wall of the reactor by compression.

[0018] (III) Beneficial Effects

[0019] The potassium fluorozirconate synthesis device of this invention uses a drive motor to rotate the stirring shaft. Combined with the meshing transmission between the first bevel gear on the fixed shaft and the second bevel gear on the stirring rod, the stirring blades simultaneously revolve around the stirring shaft and rotate on their own axis. This overcomes the limitations of the fixed stirring trajectory in the prior art. It can accelerate the initial mixing of materials in the early stage of the reaction through a large-scale mixing flow field, and enhance the diffusion effect in the middle and later stages of the reaction through strong shear force and circulating flow. It can effectively adapt to changes in material viscosity and shorten the reaction cycle. Attached Figure Description

[0026] 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.

[0027] This invention provides a potassium fluorozirconate synthesis apparatus, such as... Figure 1-4 As shown, the potassium fluorozirconate synthesis apparatus includes a reaction vessel 1 and a stirring assembly. The stirring assembly is disposed on the reaction vessel 1 and is used to stir the potassium fluorozirconate raw material.

[0028] Specifically, the stirring assembly includes a drive motor 2, which is fixedly installed on the top of the reactor 1. The output shaft of the drive motor 2 is fixedly connected to a stirring shaft 3 via a coupling. A fixed shaft 4 is fixed at the bottom of the inner cavity of the reactor 1. The stirring shaft 3 is sleeved on the outer surface of the fixed shaft 4 and can rotate around the fixed shaft 4.

[0029] Two sets of first bevel gears 5 are fixed on the outer surface of the fixed shaft 4, and several sets of fixed columns 6 are fixed on the outer surface of the stirring shaft 3. The stirring rod 7 is rotatably connected to the inside of the fixed column 6 through a mating bearing. This connection method allows the stirring rod 7 to rotate flexibly.

[0030] One end of the stirring rod 7 extends into the interior of the stirring shaft 3 and is fixed with a second bevel gear 8. The second bevel gear 8 meshes with the first bevel gear 5. Several sets of stirring blades 10 are fixed on the outer surface of the stirring rod 7.

[0031] A sealing ring 9 is embedded inside the fixed column 6. The sealing ring 9 covers the outer surface of the stirring rod 7. The sealing ring 9 can enhance the sealing between the fixed column 6 and the stirring rod 7, prevent potassium fluorozirconate raw material from leaking from the gap between the fixed column 6 and the stirring rod 7, and ensure the normal operation of the device.

[0032] Specifically, when the drive motor 2 starts, its output shaft drives the stirring shaft 3 to rotate via a coupling. When the stirring shaft 3 rotates, it drives the fixed column 6 and the stirring rod 7 to rotate together around the axis of the stirring shaft 3. Since the second bevel gear 8 meshes with the first bevel gear 5, during the rotation of the stirring rod 7 around the stirring shaft 3, the second bevel gear 8 will be subjected to the force of the first bevel gear 5, thereby driving the stirring rod 7 to rotate itself. This causes the stirring blade 10 to both revolve around the stirring shaft 3 and rotate on its own axis. This dual motion mode breaks through the limitation of fixed stirring trajectory in the existing technology and can flexibly adjust the stirring intensity and range according to different stages of material reaction. In the early stage of reaction, when the material viscosity is low, the revolution and rotation of the stirring blade 10 can form a large-scale mixing flow field, accelerating the initial mixing of materials. When the reaction enters the middle and late stages, the material viscosity increases, and the rotation of the stirring blade 10 can generate stronger shear force. At the same time, the revolution drives the material to form a circulating flow, enhancing the diffusion effect and effectively avoiding the problem of slowing down the mixing speed, thus shortening the reaction cycle.

[0033] Meanwhile, a cavity 12 is provided inside the stirring shaft 3, and a return spring 13 and a movable part 14 are sleeved on the inner side of the cavity 12. The return spring 13 is elastically supported between the cavity 12 and the movable part 14.

[0034] Specifically, a number of movable frames 15 are sleeved on the outer side of the stirring shaft 3. One end of the movable frame 15 extends into the interior of the cavity 12 and is fixed with a connecting plate 16. The bottom end of the movable part 14 is conical, and the movable part 14 is in contact with the connecting plate 16. The other end of the movable frame 15 is fixed with a scraper 11, and the scraper 11 is in contact with the inner wall of the reactor 1.

[0035] As the return spring 13 is compressed, it pushes the movable part 14 downward. The conical structure at the bottom of the movable part 14 squeezes the connecting plate 16, causing the movable frame 15 to drive the scraper 11 to move away from the stirring shaft 3 until the scraper 11 is in close contact with the inner wall of the reactor 1. Through this movement, the scraper 11 can scrape the inner wall of the reactor 1, effectively reducing the adhesion residue of potassium fluorozirconate raw material on the inner wall of the reactor 1, and further improving the raw material utilization rate and the cleanliness of the device.

[0036] In summary, this potassium fluorozirconate synthesis device, through its unique stirring component design, achieves both revolution and rotation of the stirring blade 10, solving the problems of a single stirring trajectory and inability to adapt to changes in material viscosity in existing technologies, thus improving the stirring effect. At the same time, the movement of the scraper 11 is used to clean the inner wall of the reactor 1, reducing raw material residue. It has the advantages of reasonable structure and good performance.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
