Description

Technical Field

[0001] This invention belongs to the field of reaction vessel technology, and particularly relates to a reaction vessel. Background Technology

[0002] A reaction vessel is an essential piece of equipment used in industrial production processes such as chemical production. It is used to add reactants, including liquids and solids, into the vessel and carry out chemical reactions under specific conditions such as temperature, pressure, and stirring speed to produce the target product.

[0003] Currently, most industrial reaction vessels are characterized by large volume. In order to improve reaction efficiency, the reaction is often stirred by the stirring mechanism built into the reaction vessel. During the reaction, the material system is mixed by the stirring mechanism.

[0004] Given the wide application of reactors in industrial production processes, there are numerous published reports on improvements to reactor equipment technology. For example, Chinese Patent Publication No. CN220034450U discloses a reactor for biopharmaceutical use. The specific structure includes a bottom box, an outer shell fixedly connected to the right side of the top of the bottom box, a motor fixedly connected to the bottom of the inner cavity of the outer shell, a transmission rod fixedly connected to the output end of the motor, and the bottom of the transmission rod penetrating the top of the bottom box and extending into the inner cavity of the bottom box.

[0005] This technology can effectively solve the technical defect of traditional biopharmaceutical reaction vessels, where the internal components have low stirring efficiency, resulting in insufficient mixing and reaction of drugs.

[0006] However, in actual production processes, especially in large-volume reactors, the efficiency of material system fragmentation, dissolution, and reaction under stirring conditions is often not high, especially for materials that are difficult to dissolve or refine. The specific reason is that during the reaction, the material system rotates along with the fluid inside the reactor, and the collision force between the material and the stirring mechanism during this rotation is not significant.

[0007] One specific reason is that, due to the density of the material system, materials with low density tend to be in the upper layer of the system, while the stirring paddle system is located below the liquid. Therefore, materials in the upper layer or in a suspended state are difficult to be impacted, dispersed, dissolved, and participate in chemical reactions by the stirring system.

[0008] Secondly, in the chemical reaction process, when a large-volume vessel is stirred, the main movement trend of the material system is to follow the liquid flow, making it difficult to impact the stirring system of the reaction. Specifically, as the rotating material follows the fluid rotation, the fluid cannot push the rotating material to impact the stirring system, resulting in a slow reaction process in the chemical reaction. Summary of the Invention

[0009] Based on the above background, the purpose of this invention is to provide a reaction vessel.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A reaction vessel includes a vessel body, wherein a plurality of baffles are fixedly assembled and connected within the vessel body, and through the baffles, a plurality of reaction chambers are formed within the vessel body.

[0012] The reactor also includes a layered stirring mechanism, which includes a stirring shaft and a pusher spiral plate assembly fixedly connected to the stirring shaft. The pusher spiral plate assembly includes several lower pusher liquid spiral plates and an upper pusher liquid spiral plate.

[0013] The layered stirring mechanism also includes stirring components located between the lower pushing liquid spiral plate and the upper pushing liquid spiral plate respectively;

[0014] During the stirring process, the downward-pushing liquid spiral plate pushes the reactants upward, and the upward-pushing liquid spiral plate pushes the reactants upward. By pushing the reactants upward with the downward-pushing liquid spiral plate, the stirring components can increase the dissolving, crushing, and mixing effects on the materials.

[0015] Preferably, a first partition and a second partition are fixedly connected inside the vessel body, which are spaced apart vertically.

[0016] An upper reaction chamber is formed between the first partition and the upper end of the vessel body, and an intermediate reaction chamber is formed between the first partition and the second partition.

[0017] The second partition forms a lower reaction chamber between itself and the lower end of the vessel body.

[0018] Preferably, the stirring shaft is fixedly assembled with a first downward pushing liquid spiral plate, a first upward pushing liquid spiral plate, a second downward pushing liquid spiral plate, a third downward pushing liquid spiral plate, a second upward pushing liquid spiral plate, a third upward pushing liquid spiral plate, a fourth downward pushing liquid spiral plate, and a fifth upward pushing liquid spiral plate from top to bottom.

[0019] Preferably, the stirring assembly includes a first stirring component located between the first lower pushing liquid spiral plate and the first upper pushing liquid spiral plate;

[0020] The stirring assembly also includes a second stirring component located below the second downward-pushing liquid spiral plate, the second stirring component being assembled and connected to the top of the first partition plate;

[0021] The stirring assembly also includes a third stirring component located between the third lower pushing liquid spiral plate and the second upper pushing liquid spiral plate;

[0022] The stirring assembly also includes a fourth stirring component located above the third upper liquid-pushing spiral plate;

[0023] The fourth stirring component is assembled and connected to the bottom of the second partition plate;

[0024] The stirring assembly also includes a fifth stirring component located between the fourth downward-pushing liquid spiral plate and the fifth upward-pushing liquid spiral plate.

[0025] Preferably, the first downward-pushing liquid spiral plate, the first upward-pushing liquid spiral plate, the first stirring component, the second downward-pushing liquid spiral plate, and the second stirring component are located in the upper reaction chamber;

[0026] The third downward-pushing liquid spiral plate, the second upward-pushing liquid spiral plate, and the third stirring component are located in the intermediate reaction chamber;

[0027] The third upward-pushing liquid spiral plate, the fourth stirring component, the fourth downward-pushing liquid spiral plate, the fifth upward-pushing liquid spiral plate, and the fifth stirring component are located in the lower reaction chamber.

[0028] Preferably, the first stirring component, the third stirring component, and the fifth stirring component all include an annular rotating plate, and a plurality of inner curved steel plates are welded inside the annular rotating plate;

[0029] The inner end of the inner curved steel plate is welded to the stirring shaft.

[0030] Preferably, the curved steel plate has two layers distributed on the top and bottom.

[0031] Preferably, the second stirring component and the fourth stirring component include rotating rings respectively rotatably connected to the top of the corresponding first partition and the bottom of the corresponding second partition;

[0032] Several irregularly shaped material plates are fixedly connected to the rotating ring body. The irregularly shaped material plates include those fixedly connected to...

[0033] The lower connecting part on the inner side wall of the rotating ring has an integrally formed upper vertical part, an integrally formed upper V-shaped part protruding outward, and an integrally formed lower V-shaped part concave inward.

[0034] Preferably, the top of the first partition and the bottom of the second partition are respectively fixedly connected with convex annular tracks;

[0035] The convex annular track has an annular inner groove, and the top and bottom of the rotating ring are limited by a number of balls, which roll within the annular inner groove.

[0036] Preferably, a feeding tube is assembled and connected to the reactor body, and the feeding tube has a plurality of material holes that are respectively connected to the reaction chamber.

[0037] The present invention has the following beneficial effects:

[0038] 1. By welding multiple downward-pushing liquid spiral plates and upward-pushing liquid spiral plates onto the stirring shaft, during the reaction process, when the stirring shaft rotates, the downward-pushing liquid spiral plates and upward-pushing liquid spiral plates rotate. The spiral structure of the downward-pushing liquid spiral plate pushes the material system downward (such as materials with lower density), while the upward-pushing liquid spiral plate pushes the material upward (such as materials with slightly higher density). This promotes the materials to move closer to each other, which increases the collision effect between materials and improves the chemical reaction process. It also increases the collision between materials and the stirring structure, thereby improving the dissolution, dispersion, and refinement effects of the materials.

[0039] 2. A first downward-pushing liquid spiral plate, a first upward-pushing liquid spiral plate, a second downward-pushing liquid spiral plate, a third downward-pushing liquid spiral plate, a second upward-pushing liquid spiral plate, a third upward-pushing liquid spiral plate, a fourth downward-pushing liquid spiral plate, and a fifth upward-pushing liquid spiral plate are fixedly assembled and connected to the stirring shaft from top to bottom. Correspondingly, the stirring assembly includes a first stirring component located between the first downward-pushing liquid spiral plate and the first upward-pushing liquid spiral plate, a second stirring component located below the second downward-pushing liquid spiral plate, a third stirring component located between the third downward-pushing liquid spiral plate and the second upward-pushing liquid spiral plate, a fourth stirring component located above the third upward-pushing liquid spiral plate, and a fifth stirring component located between the fourth downward-pushing liquid spiral plate and the fifth upward-pushing liquid spiral plate. This method achieves the goal of using the stirring component as a base point to push and impact the material system above and below the reaction component onto the stirring component. By doing so, materials of different densities are pushed and impacted against the stirring component, thereby improving reaction efficiency.

[0040] 3. By setting the stirring components separately in relatively independent reaction chambers, and because the stirring components and the corresponding liquid-pushing spiral plates form an integrated material action system and are independently located in the reaction chambers, the reaction chambers are used as reaction units to fully stir and react the materials in a separate manner, thereby improving the reaction effect.

[0053] Example 1

[0054] like Figure 1-7 As shown, a reaction vessel includes a vessel body 1. Two baffles are fixedly assembled and connected within the vessel body 1. Specifically, a first baffle 31 and a second baffle 311 are spaced apart vertically (the first baffle 31 and the second baffle 311 are made of stainless steel, and according to conventional methods, multiple flow holes are opened on the baffles to facilitate the movement of the material system within the vessel). Through the baffles, the vessel cavity within the vessel body 1 forms several reaction chambers. Specifically, an upper reaction chamber A is formed between the first baffle 31 and the upper end of the vessel body 1; an intermediate reaction chamber B is formed between the first baffle 31 and the second baffle 311; and a lower reaction chamber C is formed between the second baffle 311 and the lower end of the vessel body 1.

[0055] The above method divides the large-volume reactor into three relatively independent reaction chambers. The purpose of this design is to prevent materials, especially dense materials, from settling too much at the bottom of the reactor, which would result in uneven dispersion of materials during the reaction process.

[0056] To achieve independent stirring of the retained materials in each reaction chamber and improve the stirring effect, the aforementioned reactor also includes a layered stirring mechanism. This mechanism includes a stirring shaft 24 (with a stirring motor mounted on top, as is conventionally done). A pushing spiral plate assembly is fixedly connected to the stirring shaft 24, comprising several downward-pushing liquid spiral plates and upward-pushing liquid spiral plates. Specifically, unlike traditional stirring reactions, multiple downward-pushing and upward-pushing liquid spiral plates are welded onto the stirring shaft 24. The purpose is that during the reaction, when the stirring shaft 24 rotates, the downward-pushing and upward-pushing liquid spiral plates rotate as well. The spiral structure of the downward-pushing liquid spiral plates pushes the material system downwards (e.g., materials with lower density), while the upward-pushing liquid spiral plates push the material upwards (e.g., materials with higher density), promoting the materials to move closer together. This increases the collision effect between materials, improving the chemical reaction process, and also increases the collision between materials and the stirring structure, enhancing the dissolution, dispersion, and refinement effects of the materials.

[0057] The aforementioned layered mixing mechanism also includes a mixing assembly located between the lower pushing liquid spiral plate and the upper pushing liquid spiral plate respectively; the lower pushing liquid spiral plate and the upper pushing liquid spiral plate push the material toward each other in the manner described above.

[0058] During the stirring process, the downward-pushing liquid spiral plate pushes the reactants upward, and the upward-pushing liquid spiral plate pushes the reactants upward. By pushing the reactants upward with the downward-pushing liquid spiral plate, the stirring components can increase the dissolving, crushing, and mixing effects on the materials.

[0059] Example 2

[0060] like Figure 1-7 As shown, in this embodiment, based on the structure of embodiment 1, the stirring shaft 24 is fixedly assembled and connected from top to bottom with the first downward pushing liquid spiral plate 201, the first upward pushing liquid spiral plate 202, the second downward pushing liquid spiral plate 203, the third downward pushing liquid spiral plate 204, the second upward pushing liquid spiral plate 205, the third upward pushing liquid spiral plate 206, the fourth downward pushing liquid spiral plate 207, and the fifth upward pushing liquid spiral plate 208.

[0061] The upper spiral plates are all made of stainless steel. Specifically, the spiral direction of the upper spiral plate that pushes the liquid is exactly opposite to that of the lower spiral plate that pushes the liquid. During the stirring process, the material is pushed in two different directions, up and down.

[0062] Correspondingly, the stirring assembly includes a first stirring component 23 located between the first lower pushing liquid spiral plate 201 and the first upper pushing liquid spiral plate 202. During operation, the first lower pushing liquid spiral plate 201 and the first upper pushing liquid spiral plate 202 push the material from the top and bottom directions, respectively, and impact the material onto the first stirring component 23.

[0063] The mixing assembly also includes a second mixing component located below the second downward pushing liquid spiral plate 203, the second mixing component being assembled and connected to the top of the first partition 31; similarly, the second downward pushing liquid spiral plate 203 pushes the material and impacts it onto the second mixing component.

[0064] The mixing assembly also includes a third mixing component located between the third downward pushing liquid spiral plate 204 and the second upward pushing liquid spiral plate 205 (similarly, the third downward pushing liquid spiral plate 204 and the second upward pushing liquid spiral plate 205 push the material from the top and bottom directions respectively and impact it onto the third mixing component, and the structure and shape of the third mixing component are the same as those of the first mixing component 23).

[0065] The mixing assembly also includes a fourth mixing component located above the third upper pushing liquid spiral plate 206 (the fourth mixing component has the same structure as the second mixing component and is arranged symmetrically in the upper and lower positions); the fourth mixing component 4 is assembled and connected to the bottom of the second partition plate 311 (similarly, the third upper pushing liquid spiral plate 206 pushes the material onto the fourth mixing component 4 to impact and react); the mixing assembly also includes a fifth mixing component located between the fourth lower pushing liquid spiral plate 207 and the fifth upper pushing liquid spiral plate 208 (similarly, under the action of the fourth lower pushing liquid spiral plate 207 and the fifth upper pushing liquid spiral plate 208, the material system pushes and impacts the material onto the fifth mixing component from both the upper and lower directions, and the fifth mixing component has the same structure and shape as the first mixing component 23).

[0066] The above method achieves the goal of using the stirring component as a base point to push and impact the material system above and below the reaction component onto the stirring component. This method also pushes and impacts materials of different densities onto the stirring component, thereby improving reaction efficiency.

[0067] The first downward-pushing liquid spiral plate 201, the first upward-pushing liquid spiral plate 202, the first stirring component 23, the second downward-pushing liquid spiral plate 203, and the second stirring component are located in the upper reaction chamber A; the third downward-pushing liquid spiral plate 204, the second upward-pushing liquid spiral plate 205, and the third stirring component are located in the intermediate reaction chamber B; the third upward-pushing liquid spiral plate 206, the fourth stirring component 4, the fourth downward-pushing liquid spiral plate 207, the fifth upward-pushing liquid spiral plate 208, and the fifth stirring component are located in the lower reaction chamber C.

[0068] The above method achieves the goal of setting the stirring components separately in relatively independent reaction chambers. Since the stirring components and the corresponding liquid-pushing spiral plates form an integrated material action system and are independently located in the reaction chambers, the reaction chambers are used as reaction units to fully stir and react the materials in a separate manner.

[0069] Example 3

[0070] like Figure 1-7 As shown, in this embodiment, based on the structure of embodiment 1, the first stirring component 23, the third stirring component, and the fifth stirring component all include an annular rotating plate 231. The annular rotating plate 231 has several inner curved steel plates 232 welded inside (the inner ends of the inner curved steel plates 232 are welded to the stirring shaft 24); the curved steel plates are distributed in two layers, one above the other.

[0071] First, the inner curved steel plate 232 is made of 5mm thick steel plate and is formed by mechanical rolling. Its shape is designed with multiple staggered U-shaped structures. The purpose of this design is to increase the shear force points on the inner curved steel plate 232. During the stirring process, the material system can be dispersed and impact different inner curved steel plates 232 under the push of the corresponding liquid spiral plate, thereby increasing the refining and dissolving effect and improving the effect of the material participating in the reaction process.

[0072] The aforementioned second stirring component and fourth stirring component 4 include a rotating ring 331 rotatably connected to the top of the corresponding first partition 31 and the bottom of the corresponding second partition 311, respectively; a plurality of irregularly shaped material plates 34 are fixedly connected to the rotating ring 331, and the irregularly shaped material plates 34 include a lower connecting part 341 fixedly connected to the inner side wall of the rotating ring 331, the lower connecting part 341 is integrally formed with an upper vertical part 342, the upper vertical part 342 is integrally formed with an upper V-shaped part 343 protruding outward, and the upper V-shaped part is integrally formed with a lower V-shaped part 344 recessed inward.

[0073] The irregularly shaped material plate 34 with the above-mentioned irregular structure design (the irregularly shaped material plate 34 is made of steel plate with a thickness of 5mm) has the following advantages: First, it has a large stirring force, which can fully mix the material system. Second, the irregularly shaped material plate 34 has a large stirring surface, which can fully impact and refine the pushed material.

[0074] The top of the first partition 31 and the bottom of the second partition 311 are respectively fixedly connected to a convex annular track 32; correspondingly, an annular inner groove 321 is opened in the convex annular track 32 (the annular inner groove 321 is located on the inner side wall of the convex annular track 32), and a number of balls 332 are limited at the top and bottom of the rotating ring 331 (specifically, according to the existing method, a number of annularly distributed ball grooves are opened at the top and bottom of the rotating ring 331, and the balls 332 are limited in the grooves), and the balls 332 are limited to rolling in the annular inner groove.

[0075] During operation, the material system first moves toward the rotating ring 331-shaped material plate 34 structure under the push of the corresponding liquid spiral plate. Under the push of the fluid and material, the shaped material plate 34 rotates. Because the shaped material plate 34-rotating ring 331-ball 331 structure can rotate freely and flexibly in the convex ring track 32, its rotation flexibility is greatly improved, thereby improving the stirring and mixing effect.

[0076] Example 4

[0077] like Figure 1-7 As shown, in this embodiment, based on the structure of Embodiment 1, a feeding tube is assembled and connected to the aforementioned vessel body 1. The feeding tube has several material holes that connect to the reaction chambers respectively. The first partition 31 and the second partition 311 are not completely fixed to the inner wall of the vessel body 1. Specifically, there is a gap between the sidewall portion of the first partition 31 and the second partition 311 and the inner wall of the vessel body 1. The feeding tube passes through the gap, and the material holes face into each reaction chamber. Firstly, the formation of the gap facilitates the flow of material between each reaction chamber. During the reaction, the stirred material system moves within the vessel along with the solvent system, entering the reaction chamber through the gap and the flow holes on the partition, and remaining within the reaction chamber to participate in the stirring reaction in the manner described above.

[0078] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
