Description

Technical Field

[0001] This utility model relates to the field of chemical crystallization equipment technology, specifically a shear-type material crystallizer. Background Technology

[0002] Crystallization is a key unit operation in the production of petrochemicals, new coal chemicals, pharmaceuticals, food, and fine chemicals, used to separate, purify, and obtain solid products. The particle size distribution, morphology, and purity of crystalline products directly affect the quality of the final product, downstream processing performance, and commercial value.

[0003] Currently, widely used industrial crystallization equipment, such as Oslo crystallizers, DTB crystallizers, and forced circulation crystallizers, largely relies on the fluid shear force and circulation momentum provided by the agitator blades to control the crystallization process. In practical applications, for materials prone to agglomeration or requiring strict particle size control, the shear force generated by traditional agitation is insufficient to effectively break up crystal clusters and secondary crystal nuclei, easily leading to a wide particle size distribution and poor flowability in the product. Furthermore, during the crystallization process, crystals easily deposit and form scale on the vessel walls, cooling surfaces, and internal components, creating a hard, scaly layer that severely reduces heat transfer efficiency, necessitates frequent shutdowns for cleaning, and impacts production continuity and capacity.

[0004] In addition, the control of the crystallization process relies heavily on changing process parameters such as temperature and feeding rate. It lacks direct and active intervention methods for the mechanical strength of crystal particles, and cannot flexibly adapt to the different requirements for shear strength at different stages from crystal nucleus crushing to crystal growth and refinement, making it difficult to achieve precise control of product particle size. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shear-type material crystallizer, including a base, a support mounted on the base, and a crystallization cylinder fixed on the support.

[0006] The base is longer than the crystallization cylinder to ensure its stability. A right-angled bracket is used, with one side of the bracket fixed to one end of the base and the other side fixed to one end of the crystallization cylinder, so that the crystallization cylinder floats above the base, facilitating bottom feeding.

[0007] A stirring assembly is installed inside the crystallization cylinder, which includes a slitting mechanism set inside the crystallization cylinder.

[0008] The stirring assembly also includes a rotating rod movably connected inside the crystallization cylinder, a material turning mechanism for turning the material over, and a cutting mechanism for cutting the material, which are arranged opposite each other on the side of the rotating rod.

[0009] During the rotation of the rotating rod, it drives the material turning mechanism and the cutting mechanism to rotate, and the cutting mechanism and the counter-cutting mechanism form an interlaced shearing cut of the material.

[0010] One end of the crystallization cylinder is equipped with a control mechanism for controlling the continuous operation of the stirring components and adjusting the cutting fineness.

[0011] The control mechanism, as the power source for driving and spacing adjustment, can adjust the displacement of the rotating rod while driving it to rotate, thereby adjusting the spacing between the cutting mechanism and the counter-cutting mechanism to achieve the effect of coarse cutting in the early stage and fine cutting in the later stage.

[0012] As a further improvement to the above scheme, the side of the crystallizer is provided with a feed port and a conveying port arranged vertically opposite each other.

[0013] With the above technical solution, both the feed port and the conveying port are equipped with sealing caps. The feed port is used to input materials into the crystallizing cylinder, while the conveying port is used to output the materials from the crystallizing cylinder.

[0014] As a further improvement to the above scheme, the interior of the crystallizing cylinder has two horizontally opposite socket holes, and both ends of the rotating rod are fixed with socket rods, which are respectively movably sleeved in the corresponding socket holes.

[0015] With the above technical solution, the length of the sleeve rod matches the length inside the sleeve hole. However, the sleeve rods at both ends of the rotating rod cannot be fully engaged with the corresponding sleeve holes at the same time. When one end of the sleeve rod is fully engaged in the corresponding sleeve hole, the other end of the sleeve rod is only engaged in one-third of the corresponding sleeve hole, forming an adjustable displacement space. Thus, by inserting the sleeve rod into the sleeve hole, the stability of the rotating rod's rotation is ensured, while the horizontal displacement of the rotating rod can also be adjusted, thereby adjusting the distance between the side cutting mechanism and the cutting mechanism.

[0016] As a further improvement to the above solution, the material turning mechanism includes a rotating rod side, multiple connecting rods arranged along its length, and a scraper installed at the front end of the connecting rods.

[0017] The scraper has a limiting groove on its side, and a sliding block is slidably connected within the limiting groove.

[0018] One end of the scraper is provided with a limiting groove, which is connected to the limiting groove. One end of the connecting rod is provided with a connecting button, one end of which is rotatably connected to the sliding block, and the side of the connecting button is slidably connected in the limiting groove.

[0019] With the above technical solution, when the rotating rod rotates, the connecting rod drives the scraper to rotate, so that the scraper scrapes and cleans the material remaining in the adjustment groove and performs material turning, ensuring that the material is in motion and improving the shearing effect. When the displacement of the rotating rod is adjusted, the connecting button at the front end of the connecting rod drives the sliding block to slide in the limit groove, thereby ensuring that when the distance between the cutting mechanism and the cutting mechanism is adjusted, the scraper remains in the adjustment groove to perform the operation.

[0020] As a further improvement to the above solution, the cutting mechanism includes the side of the rotating rod, multiple connecting rods arranged along its length, an arc-shaped cutting blade fixed at the front end of the connecting rods, and cutting teeth provided on the side of the arc-shaped cutting blade.

[0021] With the above technical solution, when the rotating rod rotates, it drives the arc-shaped cutting blade to rotate circumferentially through the connecting rod two, and the cutting teeth at the blade edge cooperate to achieve the cutting operation of the material.

[0022] As a further improvement to the above solution, the cutting mechanism includes multiple annular cutting blades distributed along the length of the crystallizing cylinder, with mating teeth on the annular cutting blades and adjustment grooves formed between adjacent annular cutting blades.

[0023] Through the above technical solution, the scraper and the arc-shaped cutting blade are movably connected in the adjustment groove. When the arc-shaped cutting blade rotates in the adjustment groove, it forms a scissor-cutting effect with the ring-shaped cutting blade, and the material is clamped by the cutting teeth and the mating teeth, so that large agglomerated blocky materials can be crushed.

[0024] As a further improvement to the above scheme, the control mechanism includes a protective box fixed to one end of the crystallization cylinder. A rotating gear and a transmission gear are rotatably connected inside the protective box, and a transmission toothed belt meshes with the sides of the two gears.

[0025] Through the above technical solution, under the action of the meshing force of the tooth profile, when the rotating gear rotates under the action of the driving force, the transmission gear is driven to rotate simultaneously through the transmission tooth belt.

[0026] As a further improvement to the above solution, a drive motor is fixed to one end of the protective box. The output end of the drive motor passes through the inside of the protective box and is fixed with an irregular rod. The irregular rod is movably sleeved in the rotating gear.

[0027] With the above technical solution, when the drive motor is operating as the driving force, its output end drives the irregular rod to rotate, and the irregular rod drives the rotating gear to rotate.

[0028] As a further improvement to the above solution, an electric telescopic rod is fixed to the other end of the protective box. The output end of the electric telescopic rod passes through the protective box and is rotatably connected to a second irregular rod, which is movably sleeved in the transmission gear.

[0029] With the above technical solution, when the electric telescopic rod is in operation, its output end drives the irregular rod two to move back and forth in the transmission gear, while not affecting the transmission gear driving the irregular rod two to rotate.

[0030] As a further improvement to the above scheme, one end of the irregular rod is fixed with a connecting rod, and one end of the connecting rod is fixed to the sleeve rod at one end of the rotating rod.

[0031] Through the above technical solution, when the irregular rod 2 is operated by the electric telescopic rod, the force of its output end extending and retracting forward and backward drives the rotating rod to move through the connecting rod, thereby realizing the adjustment of the distance between the arc-shaped cutting blade and the ring-shaped cutting blade.

[0032] Compared with the prior art, this utility model provides a shear-type material crystallizer, which has the following features:

[0033] Beneficial effects:

[0034] 1. This shear-type material crystallizer uses a rotating rod to drive an arc-shaped cutting blade, which is coupled with a fixed annular cutting blade to form a highly efficient shearing zone. This zone actively and powerfully breaks down crystal clusters and agglomerates formed in the solution, promoting secondary nucleation. Furthermore, a unique control mechanism drives the rotating rod to move axially, seamlessly adjusting the shearing gap. This allows for precise control throughout the process, from coarse cutting to break down large particles in the early stages of crystallization to fine cutting to suppress excessive growth in the later stages. Ultimately, this results in high-quality crystal products with uniform particle size and a narrow distribution range, achieving active and precise control over crystal particle size.

[0035] 2. This shear-type material crystallizer, through the rotation rod driving the arc-shaped cutting blade, also drives the side-mounted material turning mechanism, so that the adjustment groove between the scraper and the ring-shaped cutting blade is precisely matched. During the rotation, the scraper can continuously scrape off the crystal deposits in the groove and on the inner wall of the equipment, realizing online self-cleaning. This not only ensures that the crystallization cylinder wall always has excellent heat transfer performance and improves production efficiency, but also greatly extends the continuous operation cycle of the equipment and reduces the maintenance cost of shutdown cleaning.

[0036] 3. This shear-type material crystallizer, through its high-speed rotating cutting and turning mechanisms, generates strong radial and axial flows, resulting in a much higher degree of material mixing than traditional stirring. This enhanced mixing effectively eliminates gradients in concentration and temperature, preventing localized supersaturation and making the crystallization process more stable and controllable, leading to better product consistency.

[0037] 4. This shear-type material crystallizer integrates the entire drive and adjustment system into the protective box of the control mechanism. It is powered by a drive motor and provides precise displacement through an electric telescopic rod. It has a compact structure, stable operation, and the shear gap can be adjusted remotely through the automated control system. It is easy to operate and precise to adjust, and can fully meet the needs of modern continuous and automated chemical production. Attached Figure Description

[0051] 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.

[0052] Example 1

[0053] Please see Figure 1 - Figure 7 As shown, the shear-type material crystallizer proposed in this embodiment includes a base 1, a support 2 installed on the base 1, and a crystallization cylinder 3 fixed on the support 2.

[0054] The base 1 is longer than the crystallizing cylinder 3 to ensure the stability of the crystallizing cylinder 3. It adopts a right-angled bracket. One side of the bracket 2 is fixed to one end of the base 1, and the other side of the bracket 2 is fixed to one end of the crystallizing cylinder 3, so that the crystallizing cylinder 3 is suspended above the base 1, which facilitates the bottom feeding operation.

[0055] A stirring assembly 4 is installed inside the crystallization cylinder 3. The stirring assembly 4 includes a cutting mechanism 41 provided inside the crystallization cylinder 3.

[0056] The stirring assembly 4 also includes a rotating rod 43 movably connected inside the crystallization cylinder 3. On the side of the rotating rod 43, there is a turning mechanism 44 for turning over the material (large crystals and agglomerated clumps generated during the crystallization process) and a cutting mechanism 45 for cutting the material.

[0057] During the rotation of the rotating rod 43, it drives the material turning mechanism 44 and the cutting mechanism 45 to rotate, and the cutting mechanism 45 and the cutting mechanism 41 form an interlaced shearing cut of the material.

[0058] One end of the crystallizing cylinder 3 is equipped with a control mechanism 5 for controlling the continuous operation of the stirring assembly 4 and adjusting the cutting fineness.

[0059] Among them, the control mechanism 5 serves as the power source for driving and spacing adjustment. While driving the rotating rod 43 to rotate, it can also adjust the displacement of the rotating rod 43, thereby adjusting the spacing between the cutting mechanism 45 and the cutting mechanism 41 to achieve the effect of coarse cutting in the early stage and fine cutting in the later stage.

[0060] Furthermore, the side of the crystallizing cylinder 3 is provided with a feed port 31 and a conveying port 32 arranged vertically opposite each other.

[0061] More specifically, both the feed port 31 and the conveying port 32 are equipped with sealing caps. Material is fed into the crystallizing cylinder 3 through the feed port 31, while the conveying port 32 is used to output the material from the crystallizing cylinder 3.

[0062] Furthermore, the interior of the crystallizing cylinder 3 has two horizontally opposite socket holes 33. Both ends of the rotating rod 43 are fixed with socket rods 431, and the socket rods 431 at both ends are movably sleeved in the corresponding socket holes 33.

[0063] More specifically, the length of the connecting rod 431 matches the length inside the connecting hole 33, but the connecting rods 431 at both ends of the rotating rod 43 cannot be fully connected to the corresponding connecting holes 33 at the same time. When one end of the connecting rod 431 is fully connected to the corresponding connecting hole 33, the other end of the connecting rod 431 is only connected to one-third of the corresponding connecting hole 33, forming an adjustable displacement space. Thus, by inserting the connecting rod 431 into the connecting hole 33, the stability of the rotation of the rotating rod 43 is ensured, and the horizontal displacement of the rotating rod 43 can also be adjusted, so as to adjust the distance between the side cutting mechanism 45 and the cutting mechanism 41.

[0064] Furthermore, the material turning mechanism 44 includes the side of the rotating rod 43, multiple connecting rods 441 distributed along its length, and a scraper 442 installed at the front end of the connecting rods 441.

[0065] A limiting groove 443 is provided on the side of the scraper 442, and a sliding block 444 is slidably connected in the limiting groove 443.

[0066] One end of the scraper 442 is provided with a limiting groove 445, which is connected to the limiting groove 443. One end of the connecting rod 441 is provided with a connecting button 446, one end of which is rotatably connected to the sliding block 444, and the side of the connecting button 446 is slidably connected in the limiting groove 445.

[0067] More specifically, when the rotating rod 43 rotates, it drives the scraper 442 to rotate through the connecting rod 441, so that the scraper 442 scrapes and cleans the material remaining in the adjusting groove 413 and performs material turning, ensuring that the material is in motion and improving the shearing effect. When the displacement of the rotating rod 43 is adjusted, the connecting button 446 at the front end of the connecting rod 441 drives the sliding block 444 to slide in the limiting groove 443, thereby ensuring that when the distance between the cutting mechanism 45 and the cutting mechanism 41 is adjusted, the scraper 442 remains in the adjusting groove 413 to perform the operation.

[0068] It should be further explained that the dimensions of the scraper 442 and the regulating groove 413 are matched to ensure that when the scraper 442 is scraping in the regulating groove 413, it can fully scrape the material left at the corners.

[0069] Furthermore, the cutting mechanism 45 includes the side of the rotating rod 43, multiple connecting rods 451 arranged along its length, an arc-shaped cutting blade 452 fixed at the front end of the connecting rod 451, and cutting teeth 453 provided on the side of the arc-shaped cutting blade 452.

[0070] More specifically, when the rotating rod 43 rotates, it drives the arc-shaped cutting blade 452 to rotate circumferentially through the connecting rod 451, and the cutting blade and cutting teeth 453 at the blade edge realize the cutting operation of the material.

[0071] Furthermore, the cutting mechanism 41 includes a plurality of annular cutting blades 411 arranged along the length of the crystallizing cylinder 3, with mating teeth 412 on the annular cutting blades 411, and adjustment grooves 413 formed between adjacent annular cutting blades 411.

[0072] More specifically, the scraper 442 and the arc-shaped cutting blade 452 are movably connected in the adjusting groove 413. When the arc-shaped cutting blade 452 rotates in the adjusting groove 413, it forms a scissor-cutting effect with the annular cutting blade 411, and the material is positioned by the cutting teeth 453 and the docking teeth 412, thereby enabling the crushing of larger agglomerated block materials.

[0073] Furthermore, the control mechanism 5 includes a protective box 51 fixed to one end of the crystallization cylinder 3. A rotating gear 511 and a transmission gear 512 are rotatably connected inside the protective box 51, and a transmission belt 513 meshes with the sides of the two gears.

[0074] More specifically, under the action of the meshing force of the tooth profiles, when the rotating gear 511 rotates under the action of the driving force, it drives the transmission gear 512 to rotate simultaneously through the transmission belt 513.

[0075] Furthermore, a drive motor 52 is fixed to one end of the protective box 51. The output end of the drive motor 52 passes through the protective box 51 and is fixed with a special-shaped rod 514, which is movably sleeved in the rotating gear 511.

[0076] More specifically, when the drive motor 52 is in operation, its output end drives the irregular rod 514 to rotate, and the irregular rod 514 drives the rotating gear 511 to rotate.

[0077] It should be further explained that the irregular rod 514 is a straight irregular shape (e.g., triangular, quadrangular or pentagonal, as long as the side is not a smooth cylinder, there is no limitation here), and the hole of the shaft core of the rotating gear 511 matches the side of the irregular rod 514, so that the irregular rod 514 can fully drive the rotating gear 511 to rotate.

[0078] Furthermore, an electric telescopic rod 53 is fixed to the other end of the protective box 51. The output end of the electric telescopic rod 53 passes through the protective box 51 and is rotatably connected to a second irregular rod 515. The second irregular rod 515 is movably sleeved in the transmission gear 512.

[0079] More specifically, when the electric telescopic rod 53 is in operation, its output end drives the irregular rod 515 to move back and forth within the transmission gear 512, without affecting the transmission gear 512 driving the irregular rod 515 to rotate.

[0080] Furthermore, a connecting rod 516 is fixed to one end of the irregular rod 515, and one end of the connecting rod 516 is fixed to the sleeve rod 431 at one end of the rotating rod 43.

[0081] More specifically, when the electric telescopic rod 53 operates, the force of its output end extending and retracting forward and backward drives the rotating rod 43 to move through the connecting rod 516, thereby adjusting the distance between the arc-shaped cutting blade 452 and the ring-shaped cutting blade 411.

[0082] The working principle of the shear-type material crystallizer proposed in this embodiment is as follows: During use, the material (the solution and slurry to be crystallized) is poured into the crystallization cylinder 3 through the feed inlet 31, then sealed with a sealing cap. The drive motor 52 is controlled to operate, driving the rotating gear 511 to rotate via the first shaped rod 514. Power is transmitted to the transmission gear 512 via the transmission belt 513, ultimately driving the second shaped rod 515 and the fixed rotating rod 43 to begin rotating. At this time, the electric telescopic rod 53 is in its initial position, causing the arc-shaped cutting blade 452 to... The spacing between the annular cutting blades 411 is relatively large, indicating a "coarse cutting" mode. As the solution cools, evaporates, or seed crystals are added, the crystallization process begins, and tiny crystal nuclei start to form in the solution. The rotating rod 43 drives the arc-shaped cutting blade 452 to pass at high speed through the adjusting groove 413 between the annular cutting blades 411. The two blades intersect to form a high-speed shearing zone, creating a shearing effect similar to scissors. Larger crystals are broken up by the cutting teeth 453 and the mating teeth 412. This stage breaks up the larger crystal clusters and agglomerates that formed early in the solution, promoting crystallization. Secondary nucleation increases the number of crystal nuclei and ensures uniform mixing of materials, preventing local oversaturation and creating conditions for uniform crystallization. Simultaneously, the material turning mechanism 44 works in sync, scraping the material in the regulating tank 413 with the scraper 442 to prevent material from accumulating in dead corners and turning over the material at the bottom, sending it into the high-speed shearing zone to ensure that all materials receive uniform mechanical processing. When the crystal grows to a certain stage and its final particle size needs to be controlled, the electric telescopic rod 53 is activated. The electric telescopic rod pushes the shaped rod 515 and the connecting rod 516, causing the entire rotating rod 43 to generate axial displacement around the socket 33 as the axis. This directly reduces the gap between the rotating arc-shaped cutting blade 452 and the fixed annular cutting blade 411, and the equipment enters the "fine cutting" mode. The smaller gap generates a stronger shearing force, which can further refine the growing crystal particles, effectively inhibiting excessive crystal growth and agglomeration, thereby precisely controlling the crystal particle size within the required range. After crystallization, the final uniformly sized crystal slurry is discharged from the feeding interface 32 and enters the subsequent filtration, washing, and drying processes.

[0083] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
