Description

[0002] Microchemical technology utilizes microchannel devices at the millimeter or even micrometer scale to realize chemical production processes, offering excellent controllability and without significant scale-up effects. Therefore, microchannel devices can be used to conveniently achieve the mixing and emulsification of special liquids in a controlled manner, a method that has been successfully applied in the synthesis of specialty materials. Microemulsification essentially balances the effectiveness, safety, and stability of the final product through precise manipulation, making it indispensable, especially in fields involving active substances or requiring strict dosage control.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example 1
[0042] Please see Figure 1-4 This utility model provides a technical solution:
[0043] This utility model discloses a micro-volume mixing reaction device, comprising a support frame 2, a diaphragm pump 5, a distributor 16, a confluence mechanism assembly 1, a confluence tank 3, and an emulsifying pump 17. Located on the support frame 2, the storage tank 4, diaphragm pump 5, distributor 16, confluence mechanism assembly 1, and confluence tank 3 are connected sequentially from top to bottom via connecting pipes 18, forming an integral, sealed container. The connecting pipes 18 are capillary connecting pipes made of silicone or PTFE tubing, offering a long service life and meeting the requirements for high-temperature or corrosive materials. It can be used to mix and emulsify two or more liquid materials under special environments, has a wide range of applications, and meets the reaction requirements for micro-volume emulsification in special environments.
[0044] The distributor 16 is mounted on the support bracket 2. The number of diaphragm pumps 5 and distributors 16 corresponds one-to-one with the storage tanks 4. Each set of diaphragm pumps 5 and distributors 16 is used to distribute liquid to the corresponding storage tank 4. The diaphragm pumps 5 draw material from the storage tank 4 and transport it to the distributor 16. Then, the material is transported to the manifold 3 through the manifold assembly 1. The bottom outlet pipe of the manifold 3 is connected to the three-stage emulsifying pump 17 through a pipe with a valve. Finally, through the coordinated action of the distributor 16 and the manifold assembly 1, multiple materials are first separated into finer micro-flows through the distributor 16, and then mixed simultaneously under fine micro-flow conditions through the manifold assembly 1. The multiple fully mixed materials are then concentrated and merged in the manifold 3, significantly improving the micro-channel mixing effect of the whole material and effectively avoiding blockage and damage to the material flow channel under special conditions. This ensures that the entire mixing and emulsification process is continuously effective, improves production efficiency, and meets actual mixing and emulsification needs.
[0045] The number of diaphragm pumps 5 is equal to the number of storage tanks 4, enabling one-to-one discharge of raw materials.
[0046] The diverter 16 is mounted on the support bracket 2. The diverter 16 is a closed disc-shaped container. This structural design of the diverter 16 can effectively reduce the storage time of the material passing through it, while realizing precise multiple diversion operations for the material, saving time and effort, and significantly improving the diversion effect. The upper end of the diverter 16 is provided with a first inlet 1601 connected to the diaphragm pump 5, and the lower end is provided with multiple first outlets 1602 that match the confluence mechanism assembly 1. The number of first outlets 1602 is greater than or equal to two, specifically 2n, where n is greater than or equal to 1.
[0047] The manifold assembly 1 includes a manifold body 6 and multiple manifold port devices installed on the manifold body 6. Each manifold port device is provided with a pipe installation channel that communicates with the manifold trough 3. An inlet regulating pipe is connected to the upper inlet of the pipe installation channel of each manifold port device, and an outlet manifold pipe 7 is connected to the lower outlet. The lower part of the outlet manifold pipe 7 extends into the manifold trough 3, and the lower part of the inlet regulating pipe is sealed to the outlet manifold pipe 7.
[0048] A foldable elastic seal is provided at the connection between the outlet manifold 7 and the manifold 3, ensuring a sealed connection between them. Each set of inlet regulating pipes consists of two or more individual liquid distribution pipes 8 connected together. The lower parts of all individual liquid distribution pipes 8 in each set converge and are sealed within the outlet manifold 7. The first outlet 1602 below the distributor 16 is connected one-to-one with the individual liquid distribution pipes 8 in the inlet regulating pipe of the manifold assembly 1 via a connecting pipe 18. All individual liquid distribution pipes 8 in each set of inlet regulating pipes include those for all types of materials, achieving precise mixing of all components in each set before confluence. This further ensures more thorough mixing and significantly improves the rapid mixing and confluence effect.
[0049] The manifold device is axially limited and rotatably connected to the manifold body 6; a vertically arranged fixing bolt mounting hole 9 is also provided on the manifold body 6 to facilitate the connection between the manifold device and the manifold trough 3 through the fixing bolt mounting hole 9 and the bolt.
[0050] The manifold device includes an adjusting column 10, a rotating handle 11, and an end pin 12. The adjusting column 10 has a pipe installation channel in the middle that communicates with the manifold 3. The main body 6 of the manifold plate is provided with a mounting bracket lug 13 that matches the adjusting column 10. The adjusting column 10 is rotatably mounted on the mounting bracket lug 13. The threaded end of the end pin 12 passes laterally through one side of the mounting bracket lug 13 and is fixedly connected to one end of the adjusting column 10. The end of the rotating handle 11 is provided with a bolt. The bolt at the end of the rotating handle 11 passes laterally through the other side of the mounting bracket lug 13 and is fixedly connected to the other end of the adjusting column 10. This structure can drive the adjusting column 10 to rotate by rotating the rotating handle 11, thereby controlling the rotation direction of the outlet manifold 7 and concentrating all the outlet manifolds 7 within the manifold 3.
[0051] A locking bolt 14 is also provided between each set of mounting bracket lugs 13 located on the outside of the adjusting column 10. After the angle of the adjusting column 10 is adjusted by rotating the handle 11, it is clamped laterally by the corresponding outer locking bolt 14 to ensure that the rotation angle of the outlet manifold 7 of the adjusting column 10 remains unchanged during use, and to ensure that the manifold effect continues to be effective.
[0052] An angle scale that matches the rotation angle of the rotating handle 11 is provided on the outer wall of the mounting bracket lug 13 located on one side of the rotating handle 11, which facilitates precise adjustment of multiple groups to achieve the best confluence effect.
[0053] like Figures 1-4 As shown, the main body 6 of the manifold of this utility model is circumferentially equipped with four sets of manifold port devices. The main body 6 of the manifold is a matching grid-shaped mounting bracket, and a vertically arranged fixing bolt mounting hole 9 is provided at the intersection of the mounting brackets of the main body 6 of the manifold.
[0054] Corresponding to the two sets of liquid storage tanks 3 for feeding, each set of inlet regulating pipes consists of two dispensing single pipes 8 connected together. The lower parts of the two dispensing single pipes 8 in each set of inlet regulating pipes converge and their bottoms are sealed and fitted into the outlet manifold 7. At the same time, the two dispensing single pipes 8 in each set of inlet regulating pipes are connected side by side, and the bottom of each dispensing single pipe 8 is beveled. The beveled bottoms of the two dispensing single pipes 8 are set opposite each other, and their tips are set separately on the outside. The bottom angle of this structural design allows all the dispensing single pipes 8 in each set of inlet regulating pipes to finally converge in the outlet manifold 7, increasing the contact area and achieving high-flow-rate and uniform mixing.
[0055] The specific usage process is as follows:
[0056] First, the two sets of liquid storage tanks 3 are fed in, and are respectively connected to the two sets of diverters 16. Each set of diverters 16 has four first outlets 1602. The main body of the manifold plate 6 is circumferentially distributed with four sets of manifold devices corresponding to the diverters 16. The main body of the manifold plate 6 is a grid-shaped mounting bracket that matches it. The inlet regulating pipe of the regulating column 10 of each set of manifold devices is composed of two liquid distribution single pipes 8 connected together. The two liquid distribution single pipes 8 in the regulating column 10 of each set of manifold devices are respectively connected to the first outlets 1602 of the two sets of diverters 16.
[0057] The two materials are thoroughly and slightly mixed at the ends of the two liquid-separating single tubes 8 in the outlet manifold 7 by the manifold assembly 1, and then merged in the manifold trough 3 through the outlet manifold 7.
[0058] After rotating the handle 11 to ensure that the liquid flowing out of all the outlet manifolds 7 is fully converged in the manifold 3 at the optimal angle, the corresponding locking bolts 14 are used to clamp it laterally to ensure that the rotation angle of the outlet manifolds 7 of the adjusting column 10 remains unchanged during use, thus ensuring that the confluence effect continues to be effective.
[0059] The bottom outlet pipe of the manifold 3 is connected to the three-stage emulsification pump 17 through a pipe with a valve, which finally realizes the micro-mixing and emulsification of all raw materials.
[0060] Meanwhile, a viewing window 19 matching the bottom of the outlet manifold 7 is provided on the manifold 3, which is used to observe and adjust the flow during the adjustment of the bottom angle of the outlet manifold 7 in the manifold 3.
[0061] Ultimately, through the coordinated action of the diverter 16 and the confluence mechanism component 1 of this utility model, multiple materials are first separated into finer micro-flows by the diverter 16, and then mixed simultaneously by the confluence mechanism component 1 under fine micro-flow conditions. The multiple fully mixed materials are then concentrated and merged in the confluence tank 3, which significantly improves the micro-channel mixing effect of the materials and effectively avoids the occurrence of material flow channel blockage and damage under special conditions, ensuring that the entire mixing and emulsification process is continuously effective, improving production efficiency, and meeting actual mixing and emulsification needs. Example 2
[0062] Please see Figure 4-6 This utility model provides a technical solution:
[0063] The micro-volume confluence mixing reaction device of this utility model has the same structure and function as that of Example 1. The same structural and functional parts will not be described in detail. The difference is as follows:
[0064] like Figures 5-7As shown, in the micro-volume mixing reaction device of this utility model, the inlet regulating pipe of the regulating column 10 of the manifold device consists of two single-tube separators 8. The two single-tube separators 8 in each set of regulating columns 10 are connected together by a Y-shaped tube 15, and the bifurcation point of the Y-shaped tube 15 is higher than the height of the regulating column 10. Specifically, the Y-shaped tube 15 includes a vertical tube 1501 and a side branch tube 1502 that penetrate the pipe installation channel on the regulating column 10. The upper ends of the vertical tube 1501 and the side branch tube 1502 are provided with plastic sleeve joints 1503 for fixing the single-tube separators 8. One single-tube separator 8 is sealed and inserted into the vertical tube 1501 and extends into the pipe installation channel at a position 10mm away from the outlet. The other single-tube separator 8 is sealed and inserted into the side branch tube 1502 and does not exceed the bifurcation point of the Y-shaped tube 15. The included angle between the vertical tube 1501 and the side branch tube 1502 is an acute angle.
[0065] During use, the liquid in the side branch pipe 1502 flows from the bifurcation point of the Y-shaped pipe 15 into the vertical pipe 1501, flows down along the side wall of the liquid distribution tube 8 inside, and finally flows into the bottom of the liquid distribution tube 8 in the vertical pipe 1501 for thorough micro-mixing, which further improves its requirement for thorough micro-mixing.
[0066] Finally, all the individual mixed materials converge into one stream in the manifold 3. The mixed material is then transported through valves and pipes to the three-stage emulsifying pump 17 for emulsification, and the material is output after completion. This structure can further meet the needs of materials with corrosive properties or special protection requirements.
[0067] In summary, the micro-volume mixing reaction device of this invention utilizes a multi-stage capillary diversion into microchannels for batch microchannel mixing, achieving sustainable micro-emulsification. This significantly reduces the scale-up effect while ensuring more thorough mixing and emulsification, and minimizes microchannel blockage and damage. This micro-volume mixing reaction device meets the requirements for mixing and emulsifying high-temperature and corrosive materials.
[0068] The above are merely embodiments of this utility model. For example, the diverter 16 has a one-inlet and multiple-outlet structure. The illustration shows a one-inlet and four-outlet structure as an example. In practice, it can be customized according to requirements. One-inlet and two-outlet, one-inlet and four-outlet, one-inlet and eight-outlet, etc. can all be customized. The actual required quantity can be designed to match the corresponding quantity of various materials required, and all of these can realize the micro-flow mixing reaction device of this utility model.
[0069] 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.
