Description

Technical Field

[0001] The utility model relates to the technical field of fluid mixing equipment, in particular to a mixing device. Background Art

[0002] In the pharmaceutical industry, the mixing process is the basic unit operation in the pharmaceutical process. The mixing effect of its equipment directly affects the efficiency of chemical reactions and product quality. Especially in the process of API synthesis, drug preparation and biopharmaceuticals, efficient mixing technology is the key to improving production efficiency and product quality. In recent years, with the in-depth research and development of mixing technology, efficient mixing equipment has become an important factor in promoting technological progress in the pharmaceutical and related industries. Among them, the equipment that uses precision-machined static mixing elements to mix materials in the tube has been increasingly favored because of its dual advantages of achieving efficient mixing and heat exchange. Static high-efficiency mixers, through different complex structure mixing elements fixed inside the pipeline, can achieve the segmentation, crossover, reorganization and re-segmentation of the fluid to form a complex fluid form, and use the changing flow channel to generate shear force, thereby accelerating the mixing and reaction of the liquid. This mixing method reduces energy consumption and maintenance costs because there are no moving parts. At the same time, it can self-adjust the mixing path according to the fluid characteristics to optimize the mixing effect.

[0003] However, existing mixing technologies such as blade agitators, stirring mixing kettles and circulation mixers, although they can meet the mixing requirements to a certain extent, the mixing effect for heterogeneous fluids (such as liquid-liquid heterogeneous systems) is often unsatisfactory. For example, the axial flow high-efficiency mixer disclosed in Chinese patent CN202010503881.4 can guide the flow in the pipeline to achieve material mixing, but due to the limitations of the "W"-shaped design of its mixing components, it is difficult for the fluid to effectively cross-merge after shearing, resulting in poor mixing uniformity.

[0009] Furthermore, the mixing device also includes a heat exchange structure, which is sleeved on the outer circumference of the mixing body, and a heat exchange medium flow channel is formed between the inner wall of the heat exchange structure and the outer wall of the mixing body.

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] See also Figures 1 to 9 As shown, the utility model provides a mixing device, which includes: a mixing body 10, having a mixing chamber 11 and a liquid inlet 12 and a liquid outlet 13 connected to the mixing chamber 11; a mixing structure 20, installed in the mixing chamber 11, the mixing structure 20 is located between the liquid inlet 12 and the liquid outlet 13, the mixing structure 20 includes a plurality of liquid passages, at least some of the liquid passages have different liquid outlet directions, at least some of the liquid passages cooperate with each other to pass through the mixing structure 20 along the liquid delivery direction; the mixing structure 20 includes The invention comprises a first hollow structure and / or a second hollow structure, wherein the first hollow structure is formed by a plurality of first hollow bodies 21 arranged in an array and connected to each other, the first hollow body 21 being a polyhedral structure, and at least two surfaces of the first hollow body 21 are provided with liquid passages connected to the inner cavity of the first hollow body 21, and the second hollow structure is formed by a plurality of second hollow bodies 22 arranged in an array and connected to each other, the second hollow body 22 being a spherical structure formed by a plurality of rod structures connected to each other, and the spherical structure having at least two liquid passages connected to each other.

[0027] In this embodiment, two or more liquids to be mixed enter the mixing chamber 11 through the liquid inlet 12, and are discharged from the liquid outlet 13 after passing through the mixing structure 20. The mixing structure 20 has multiple liquid passages, and the liquid outlet directions of some of the liquid passages are different, that is, the liquid to be mixed will experience different flow paths and direction changes when passing through the mixing structure 20, which can promote the full contact and redistribution of the liquid to be mixed. When the liquid to be mixed passes through the multiple liquid passages of the mixing structure 20, it will be cut and diverted by the physical part of the mixing structure 20, and the liquid to be mixed will be distributed in different liquid passages. Since at least some of the liquid passages cooperate with each other to penetrate the mixing structure 20, the liquid to be mixed can finally converge at the liquid passage as the liquid outlet end of the mixing structure 20 and flow out of the mixing structure 20. Through the above-mentioned arrangement, the liquid to be mixed can be counteracted, diverted, etc. when passing through the mixing structure 20, which can reduce the probability of stratification of the liquid to be mixed in the mixing chamber 11, and thus can improve the mixing effect of liquid-liquid heterogeneous phases in the mixing chamber 11.

[0028] The first hollow body 21 adopts a polyhedral structure. When the liquid to be mixed flows through the first hollow body 21, the multiple edges and vertices of the polyhedral structure will guide the liquid to be mixed to form a complex flow path, so that the liquid to be mixed flows in different directions. Since at least two surfaces of the first hollow body 21 are provided with liquid passages connected to the inner cavity of the first hollow body 21, that is, the liquid to be mixed enters and leaves the first hollow body 21 from different liquid passages on at least two surfaces, so that the liquid to be mixed entering from different directions will collide with each other in the inner cavity of the first hollow body 21, that is, the liquid flows to be mixed collide and mix with each other in the first hollow body. This collision mechanism can increase the turbulence and shearing effect between the fluids, and effectively promote the uniform mixing of the liquid to be mixed. Through the above-mentioned arrangement, the liquid to be mixed can be divided into multiple thin streams when passing through the first hollow structure, and flow into multiple different liquid flow channels. When passing through the liquid flow channels, the liquid to be mixed will not only be divided, but also merged again at the outlet position of the first hollow structure. The multiple divisions and merges in this process can break up and recombine the heterogeneous components in the liquid to be mixed, which is beneficial to the uniform distribution of the components inside the liquid, thereby reducing stratification and improving the mixing effect and reaction efficiency.

[0029] When the liquid to be mixed enters the second hollow structure, it will be guided and dispersed to the different rod structures of the spherical structure, thereby generating a complex flow pattern inside the spherical structure. The spherical structure has at least two interconnected liquid passages, so that the liquid to be mixed can enter and leave the spherical structure from different directions. Since the second hollow structure is formed by an array of multiple second hollow segments 22 arranged and connected, when the liquid to be mixed passes through the second hollow structure, it will be divided into multiple thin streams and produce mutual impact inside the spherical structure, thereby reducing the probability of stratification of liquid-liquid heterogeneous fluids in the mixing chamber 11.

[0030] In addition, since the mixing structure 20 has multiple liquid-passing channels, on the one hand, the mixing structure 20 has a high specific surface area, that is, it can increase the contact area between the fluid and the mixing structure 20. For the heat exchange process, this means that the fluid can contact more surfaces of the mixing structure 20, thereby increasing the effective area of ​​heat exchange. The provision of multiple liquid-passing channels will guide the fluid to form a complex flow path, causing the fluid to undergo multiple turns and disturbances when passing through the mixing structure 20, forming turbulence, which can significantly enhance thermal convection inside the fluid, thereby improving heat exchange efficiency. On the other hand, it can reduce pipeline resistance and meet the passage of a larger flow rate of liquid to be mixed.

[0031] In one embodiment of the present invention, there are multiple mixing structures 20, and the multiple mixing structures 20 are arranged in sequence along the conveying direction of the liquid.

[0032] In this embodiment, there are multiple mixing structures 20, so that the liquid to be mixed will undergo multi-stage mixing during the transportation process, so that the liquid to be mixed can undergo multiple offsets, cutting, diversion, and convergence, thereby making the heterogeneous liquid evenly mixed in the mixing chamber 11, thereby improving the mixing effect of liquid-liquid heterogeneous fluids.

[0033] See also Figures 1 to 5 As shown, in one embodiment of the utility model, the first hollow split body 21 includes a plurality of first polygons 211 and a plurality of second polygons 212, and the plurality of first polygons 211 and the plurality of second polygons 212 are combined with each other to form a polyhedral structure, and at least part of the first polygons 211 and at least part of the second polygons 212 have liquid passages.

[0034] In this embodiment, the first hollow body 21 is surrounded by a plurality of first polygons 211 and a plurality of second polygons 212. The edges and faces of these polygons are interlaced to provide a multi-directional flow path for the fluid to be mixed. When the liquid to be mixed enters the first hollow body 21, it will flow in from the liquid passages on different polygons, and will produce mutual impact inside the polyhedral structure, which will help to break the stable stratification of the fluid and reduce the probability of stratification of liquid-liquid heterogeneous fluid in the mixing chamber 11.

[0035] In one embodiment, each side of the first polygon 211 and the second polygon 212 is a columnar structure, and the diameter of the columnar structure ranges from 0.1 mm to 5 mm to ensure the structural strength of the first hollow body 21 .

[0036] See also Figure 1 , Figures 6 to 9 As shown, in one embodiment of the utility model, the rod structure is a cross-shaped rod 221, one end of a plurality of cross-shaped rods 221 are connected, and the other ends of the plurality of cross-shaped rods 221 are arranged along the circumferential direction to form a spherical structure, and a liquid passage is formed between at least two cross-shaped rods 221.

[0037] In this embodiment, the structural feature of the cross-shaped rod body 221 is that it has extensions in four directions. When these cross-shaped rod bodies 221 are connected into a spherical structure, they will form a complex structure that is intertwined with each other. After the liquid to be mixed enters the spherical structure, the liquid passage channel formed between the cross-shaped rod bodies 221 can divide the fluid into multiple streams, so that the liquid to be mixed is fully mixed under the action of multi-directional flow forces, thereby improving the mixing effect and reducing stratification.

[0038] It should be noted that, since the first hollow body 21 of the present application is composed of a plurality of first polygons 211 and a plurality of second polygons 212, and the second hollow structure is formed by an array of a plurality of second hollow bodies 22 arranged and connected, and the second hollow body 22 is formed by connecting a plurality of rod structures, by adjusting the angles and lengths of the sides of the first polygon 211 and the second polygon 212, and by adjusting the angles and sizes of the cross-shaped rod body 221, the mixing device of the present application can adapt to working conditions such as a large ratio of the two materials, different flow rates and different flow rates of the liquids to be mixed, etc.

[0039] In a conventional mixing device, extreme differences in material ratios may result in uneven mixing. For example, a large flow of liquid will quickly cover another small flow of liquid, forming a layered or wrapped phenomenon, thereby affecting the final mixing effect. The mixing device of the present application, through its unique design, can promote full contact and dispersion between fluids and ensure uniform mixing even when the material ratio is large. Pressure drop refers to the pressure loss caused by friction, turbulence and other factors when the fluid passes through a pipeline or a mixing device. By adjusting the angle and length of each side of the first polygon 211 and the second polygon 212, and by adjusting the angle and size of the cross-shaped rod 221, the friction resistance of the fluid during the mixing process can be reduced, thereby reducing the pressure drop, reducing the required pumping energy, and reducing the operating cost. In a mixing device, dead corners refer to areas where the fluid is difficult to reach or is not mixed sufficiently. These areas may cause material deposition or incomplete local reaction, affecting the mixing effect and product quality. The mixing structure 20 of the present application can ensure that the fluid passes through the mixing structure 20 unimpeded, and there is no space for fluid retention, thereby avoiding the formation of dead corners, preventing blockage, and extending the service life of the mixing device.

[0040] In one embodiment, the first polygon 211 is a quadrilateral, the second polygon 212 is a hexagon, and the first hollow body 21 is surrounded by six quadrilaterals and eight hexagons. The six quadrilaterals are arranged in pairs, and the two quadrilaterals in each group are arranged opposite to each other, of which two quadrilaterals serve as the top and bottom surfaces, and the remaining four quadrilaterals serve as the side surfaces and are located between the top and bottom surfaces and perpendicular to the top and bottom surfaces. The eight hexagons are distributed between the top and bottom surfaces in two layers, and each layer includes four hexagons arranged along the circumference. The four sides of each quadrilateral serving as the side surface also serve as one side of the four hexagons adjacent to the quadrilateral, the four sides of the quadrilateral serving as the top surface also serve as one side of the four hexagons adjacent to the quadrilateral, and the four sides of the quadrilateral serving as the bottom surface also serve as one side of the four hexagons adjacent to the quadrilateral. The liquid passage of the first hollow body 21 is the hollow area surrounded by the four sides of the quadrilateral and the hollow area surrounded by the six deformations of the hexagon.

[0041] Specifically, the above quadrilateral is a square.

[0042] In one embodiment, the second hollow split body 22 is formed by connecting 12 cross-shaped rod bodies 221, and the 12 cross-shaped monomers are grouped into four to form a first group of cross-shaped monomers, a second group of cross-shaped monomers and a third group of cross-shaped monomers. The four cross-shaped monomers in the same group are arranged in sequence along the circumferential direction, and the first group of cross-shaped monomers and the third group of cross-shaped monomers are symmetrically arranged about the second group of cross-shaped monomers. Each cross-shaped monomer includes a first section 2211 and a second section 2212 that are perpendicular to each other. The first sections 2211 of all cross-shaped monomers are connected, and the four cross-shaped monomers of the first group are alternately arranged with the four cross-shaped monomers of the second group along the circumferential direction. The second sections 2212 of two adjacent cross-shaped monomers of the first group and the second sections 2212 of the cross-shaped monomers of the second group located between the two second sections 2212 form a triangular structure, and the second sections 2212 of two adjacent cross-shaped monomers of the third group and the second sections 2212 of the cross-shaped monomers of the second group located between the two second sections 2212 form a triangular structure.

[0043] In one embodiment of the utility model, the hybrid structure 20 includes a first hollow structure and a second hollow structure, the first hollow structure is formed by a plurality of first hollow split bodies 21 arranged in an array and connected, the first hollow split body 21 is a polyhedral structure, and at least two surfaces of the first hollow split body 21 are provided with liquid passages connected to the inner cavity of the first hollow split body 21, and the second hollow structure is formed by a plurality of second hollow split bodies 22 arranged in an array and connected, the second hollow split body 22 is a spherical structure formed by a plurality of rod structures connected, and the spherical structure has at least two liquid passages connected to each other.

[0044] In this embodiment, the first hollow body 21 is a polyhedral structure, and at least two surfaces of the first hollow body 21 are provided with liquid passages connected to the inner cavity of the first hollow body 21. When the liquid to be mixed enters the first hollow structure, the liquid to be mixed will form multi-directional counterflow and diversion, increase the irregularity of the flow of the liquid to be mixed, and promote the liquid to be mixed to form turbulence in the mixing chamber 11, avoiding the formation of stratification and improving the mixing uniformity. The provision of the liquid passage allows the liquid to be mixed to undergo multiple cutting, counterflow and re-merger when passing through the second hollow structure, which helps the liquid to be mixed to achieve higher mixing uniformity.

[0045] like Figure 1 As shown, in one embodiment of the utility model, there are multiple first hollow structures and multiple second hollow structures, and the multiple first hollow structures and the multiple second hollow structures are alternately arranged in the mixing chamber 11 along the liquid delivery direction, which can achieve multi-stage mixing of the liquids to be mixed and significantly improve the mixing effect.

[0047] In this embodiment, the heat exchange structure 30 is arranged to effectively control the temperature of the liquid in the mixing chamber 11. That is, by circulating a specific heat exchange medium (such as water, oil, air or refrigerant, etc.) in the heat exchange medium flow channel 31, heat can be absorbed or released as needed, thereby accurately adjusting the temperature of the fluid in the mixing chamber 11, which is very important for chemical reactions that need to be mixed under specific temperature conditions, and can improve reaction efficiency and product quality.

[0048] In one embodiment, the mixing body 10 and the heat exchange structure 30 are both tube structures, and the length of the heat exchange structure 30 is greater than the length of the mixing body 10. The heat exchange structure 30 can completely cover the mixing body 10, so that the heat exchange effect can be ensured. The diameter of the mixing structure 20 ranges from 6 mm to 50 mm, and the length can be set according to actual needs.

[0049] In one embodiment, the mixing body 10 is a tube structure, and the tube wall thickness of the mixing body 10 is in the range of 0.5 mm to 5 mm to ensure the structural strength of the mixing body 10 .

[0050] In one embodiment, the mixing body 10 is a circular tube, the mixing structure 20 is a cylindrical structure, and the outer wall surface of the mixing structure 20 is in contact with the inner wall surface of the mixing chamber 11 .

[0051] like Figure 1 As shown, in one embodiment of the utility model, a heat exchange medium inlet 32 ​​and a heat exchange medium outlet 33 are provided on the heat exchange structure 30 , and the heat exchange medium inlet 32 ​​and the heat exchange medium outlet 33 are both connected to the heat exchange medium flow channel 31 .

[0052] In this embodiment, the heat exchange medium inlet 32 ​​and the heat exchange medium outlet 33 are arranged at intervals along the length direction of the mixing body 10. The heat exchange medium enters the heat exchange medium flow channel 31 through the heat exchange medium inlet 32 ​​and can flow out from the heat exchange medium outlet 33 to achieve control of the temperature of the liquid in the mixing chamber 11.

[0053] like Figure 1 As shown, in one embodiment of the present invention, the mixing device further includes at least two branch pipelines 40 , and the liquid outlet ends of the branch pipelines 40 are connected to the liquid inlet 12 .

[0054] In this embodiment, the liquid inlet end of the branch pipeline 40 is used to connect to an external liquid supply device, and the liquid to be mixed enters the mixing chamber 11 through the branch pipeline 40, flows through the mixing structure 20, and then flows out from the liquid outlet 13. Through the above arrangement, two or more liquids to be mixed can be added to the mixing chamber 11.

[0055] In one embodiment, the diameter of the branch pipeline 40 ranges from 3 mm to 20 mm, and the length ranges from 5 mm to 30 mm.

[0056] like Figure 1 As shown, in one embodiment of the utility model, the mixing device also includes a liquid inlet pipe, a first liquid outlet pipe and a second liquid outlet pipe, the liquid inlet pipe and the first liquid outlet pipe are both connected to the heat exchange structure 30, the liquid inlet pipe is connected to the heat exchange medium inlet 32, the first liquid outlet pipe is connected to the heat exchange medium outlet 33, the second liquid outlet pipe is connected to the mixing body 10, and the second liquid outlet pipe is connected to the liquid outlet 13 of the mixing body 10.

[0057] It should be noted that the traditional mixing structure 20 requires a large flow rate, and the flow rate required for heterogeneous mixing is relatively high. In addition, for conventional liquid-liquid heterogeneous static mixers, there are disadvantages such as low mixing efficiency, large structural aspect ratio, easy re-stratification of mixed materials, large pipeline resistance, high pumping pressure required, low heat transfer efficiency, inability to process and manufacture small-scale pipelines, and inability to be suitable for working conditions with a large ratio of two materials. The mixing device of the present application has a compact structure. At the same time, due to the unique structural design, it has the advantages of saving space, being suitable for various types of liquid-liquid heterogeneous reactions, long service life, easy maintenance, and efficient mixing. In addition, the efficient mixing performance can shorten the production cycle and reduce production costs.

[0058] In one embodiment, the mixing structure 20 may be made of stainless steel or titanium alloy.

[0059] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: a mixing body and a mixing structure are provided, the mixing structure has a plurality of liquid passages, and the liquid outlet directions of some of the liquid passages are different, that is, the liquid to be mixed will experience different flow paths and direction changes when passing through the mixing structure, which can promote full contact and redistribution of the liquid to be mixed. When the liquid to be mixed passes through the plurality of liquid passages of the mixing structure, it will be cut and diverted by the physical part of the mixing structure, and the liquid to be mixed will be distributed in different liquid passages. Since at least some of the liquid passages cooperate with each other to pass through the mixing structure, the liquid to be mixed can finally converge at the liquid passage as the liquid outlet end of the mixing structure and flow out of the mixing structure. Through the above-mentioned arrangement, the liquid to be mixed can be counteracted, diverted, etc. when passing through the mixing structure, which can reduce the probability of stratification of the liquid to be mixed in the mixing chamber, thereby improving the mixing effect of liquid-liquid heterogeneous phases in the mixing chamber.
