Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering, in particular to a reaction system for preparing supramolecular complexes. Background Art

[0002] Supramolecular refers to an organizational entity with higher complexity that transcends the chemical effects of molecules. For practitioners in the cosmetics field, supramolecular is defined as: molecules with different functions are recombined into a new supramolecular structure through design. This structure not only retains the functions of the original molecules, but also achieves mutual synergy, so that the efficacy is upgraded to 1+1>2. The application of supramolecular in the cosmetics field can be roughly divided into two categories: 1. Supramolecular extraction of plant extracts with specific solvents; 2. Supramolecular combination based on the principle of combinable cosmetic functions to achieve functional diversification such as penetration enhancement and solubility enhancement. From the perspective of extraction, the extraction conditions of supramolecular extraction technology are relatively harsh, and may involve long-term extraction processes such as high temperature and high pressure; from the perspective of finished product application, supramolecular assembly technology does not require harsh reaction conditions and requires maintaining sufficient mixing of materials.

[0003] Taking CN118593367A as an example, a 4-butylresorcinol mesostructured supramolecular gel, its preparation method, and cosmetic composition, the process for assembling the 4-butylresorcinol mesostructured supramolecular gel is not demanding, and the core key control method is the uniformity of mixing.

[0004] The technical problem solved in this case is how to improve the mixing uniformity of polymer complex reactions. Utility Model Content

In the reaction system, a solution flows in a first microchannel and a second microchannel, and a turbulence module in the first microchannel and the second microchannel is used to cause the solution to collide and mix in the first microchannel and the second microchannel, thereby improving the fluidity of the solution in the first microchannel and the second microchannel, so that the solution can collide and mix multiple times in the first microchannel and the second microchannel, and finally a uniformly mixed solution is obtained from the liquid outlet, thereby improving the reaction efficiency in the supramolecular preparation process.

[0006] To achieve the above objectives, this application discloses:

[0007] A reaction system for preparing a supramolecular complex includes a first substrate, a second substrate, and a microchannel unit; the first substrate is composed of a first upper substrate and a first lower substrate; the second substrate is composed of a second upper substrate and a second lower substrate; the first upper substrate is provided with a liquid inlet, and the first lower substrate is provided with a liquid outlet; the microchannel unit is a transparent plastic plate, and the first microchannel and the second microchannel are provided in the plastic plate; the first upper substrate and the first lower substrate clamp one end of the plastic plate, and the second upper substrate and the second lower substrate clamp the other end of the plastic plate; a buffer cavity is provided in the second substrate; the input end of the first microchannel is connected to the liquid inlet; the output end of the second microchannel is connected to the liquid outlet; the output end of the first microchannel, the input end of the second microchannel and the buffer cavity are connected; a turbulence module is provided in both the first microchannel and the second microchannel.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] Please refer to Figures 1 to 8 A reaction system for preparing a supramolecular complex comprises a first substrate 1, a second substrate 2, and a microchannel unit 3; the first substrate 1 is composed of a first upper substrate 11 and a first lower substrate 12; the second substrate 2 is composed of a second upper substrate 21 and a second lower substrate 22; the first upper substrate 11 is provided with a liquid inlet 111, and the first lower substrate 12 is provided with a liquid outlet 121; the microchannel unit 3 is a transparent plastic plate, and the plastic plate is provided with a first microchannel 33 and a second microchannel 34; the first upper substrate The body 11 and the first lower base 12 clamp one end of the plastic plate, and the second upper base 21 and the second lower base 22 clamp the other end of the plastic plate; a buffer cavity is provided in the second base 2; the input end 311 of the first microchannel is connected to the liquid inlet 111; the output end 321 of the second microchannel is connected to the liquid outlet 121; the output end 312 of the first microchannel and the input end 322 of the second microchannel are connected to the buffer cavity; a spoiler module 36 is provided in the first microchannel 33 and the second microchannel 34.

[0022] In actual application, the staff inputs the raw material for forming the supramolecular structure, that is, the solution to be mixed, from the liquid inlet 111 of the first matrix 1 into the first microchannel 33, and flows from the first microchannel 33 to the second microchannel 34, and finally obtains a mixed solution at the liquid outlet 121 of the first matrix 1. Specifically, the solution will pass through the turbulence module 36 arranged in the first microchannel 33 in the first microchannel 33, and collide under the action of the turbulence module 36. After multiple collisions, the fluidity of the solution will be improved. That is to say, the solution can undergo multiple collisions and mixing through the turbulence module 36, so that the solution undergoes multiple collisions and mixing in the first microchannel 33. Similarly, multiple collisions and mixing also occur in the second microchannel 34, so that after the solution passes through the first microchannel 33 and the second microchannel 34 from the liquid inlet 111, a uniformly mixed solution is obtained from the liquid outlet 121. On the other hand, due to multiple collisions, the fluidity of the solution will be improved, which is conducive to the mixing of the solution.

[0023] Preferably, the plastic plate is formed by combining a first plastic plate 31 and a second plastic plate 32 ; the first microchannel 33 and the second microchannel 34 are located on the intersection surface of the first plastic plate 31 and the second plastic plate 32 .

[0024] In the above design, the plastic material can be used to seal the solution through the elasticity and smoothness of the plastic. Under the compression of the first substrate 1 and the second substrate 2, the first plastic plate 31 and the second plastic plate 32 can be tightly fitted together so that the solution will not be lost. In addition, the plastic can also be made of transparent plastics such as PC and PMMA, which can facilitate the staff to intuitively observe the actual condition of the solution.

[0025] More preferably, the input end 311 of the first microchannel is located on the upper surface of the first plastic plate 31 ; and the output end 321 of the second microchannel is located on the lower surface of the second plastic plate 32 .

[0026] Through the above design, the solution can flow from the liquid inlet 111 of the first substrate 1 to the first microchannel 33 under the action of gravity, and can flow from the second microchannel 34 to the liquid outlet 121 of the first substrate 1, which is conducive to the flow of the solution.

[0027] More preferably, the output end 312 of the first microchannel and the input end 322 of the second microchannel are both located on the end surface of the first plastic plate 31 and / or the second plastic plate 32 .

[0028] In this embodiment, the solution can flow to the second substrate 2 through the output end 312 of the first microchannel. Since the solution is continuously input into the liquid inlet 111 and the fluidity of the solution is improved under the action of the spoiler module 36, the solution can flow from the end face of the first plastic plate 31 to the second substrate 2, and can flow from the second substrate 2 to the end face of the second plastic plate 32.

[0029] More preferably, the first microchannel 33 and the second microchannel 34 are located on the first plastic plate 31, and the spoiler module 36 is located on the second plastic plate 32; or, the first microchannel 33 and the second microchannel 34 are located on the second plastic plate 32, and the spoiler module 36 is located on the first plastic plate 31.

[0030] In this embodiment, the first microchannel 33 and the second microchannel 34 are both located on the first plastic plate 31, and the spoiler module 36 is located on the second plastic plate 32. In this way, the two ends of the first plastic plate 31 and the second plastic plate 32 are fixed to the first upper substrate 11, the first lower substrate 12, the second upper substrate 21, and the second lower substrate 22, so that the spoiler module 36 is located in the first microchannel 33 and the second microchannel 34. Through this combination, it is convenient for staff to maintain and clean the first plastic plate 31 and the second plastic plate 32.

[0031] More preferably, the spoiler module 36 is a spoiler block; an expansion portion 35 is provided at positions corresponding to the first microchannel 33 , the second microchannel 34 and the spoiler module 36 ; and the width of the expansion portion 35 is greater than the width of the corresponding first microchannel 33 , the second microchannel 34 .

[0032] In the above design, the expansion portion 35 can be used to accommodate and place the spoiler, so that when the first plastic plate 31 and the second plastic plate 32 are combined together, the solution can collide with the spoiler and continue to move in the flow direction under the guidance of the expansion portion 35, and this method can also help improve the fluidity of the solution.

[0033] More preferably, the projection of the expansion portion 35 on the horizontal plane is circular or elliptical; and at least one inner recess 361 is provided on the side of the spoiler facing the fluid flow.

[0034] In this embodiment, the projection of the expansion portion 35 on the horizontal plane is circular, and the concave portion 361 of the spoiler can cause the solution to collide with the concave portion 361 when passing through the concave portion 361 and then flow toward both sides, which is beneficial to improving the fluidity of the solution and promoting the uniform mixing of the solution.

[0035] Furthermore, the projection of the spoiler on the water surface is fishbone-shaped; along the direction of fluid flow, the spoiler has at least two layers of inner recesses 361 ; each layer of inner recesses 361 is equidistant from the side wall of the expansion portion 35 .

[0036] In this embodiment, the spoiler has three layers of inner recesses 361, but is not limited to three layers of inner recesses 361. Since the solution will flow to both sides after colliding with the inner recesses 361, the equal distance between the inner recesses 361 and the side walls of the expansion portion 35 is beneficial to improving the mixing uniformity and fluidity of the solution.

[0037] Preferably, the buffer cavity includes a first cavity 211, a second cavity 221 and a connecting channel 23 connecting the first cavity 211 and the second cavity 221; the first cavity 211, the second cavity 221 and the connecting channel 23 are located on the intersection surface of the second upper base 21 and the second lower base 22; the connecting channel 23 is connected to the middle part of the first cavity 211 and the second cavity 221.

[0038] Through the above design, the solutions in the first cavity 211 and the second cavity 221 can be connected through the connecting channel 23, so that the solution passing through the first microchannel 33 can flow from the first cavity 211 to the second cavity 221, and finally flow to the second microchannel 34, thereby ensuring that the flow direction of the solution can pass through the first microchannel 33 and the second microchannel 34 and then be discharged outward from the liquid outlet 121.

[0039] A third cavity 112 is provided on the lower surface of the first upper substrate 11, and a fourth cavity 122 is provided on the upper surface of the second upper substrate 21. The third cavity 112 is connected to the liquid inlet 111 and the input end 311 of the first microchannel; the fourth cavity 122 is connected to the liquid outlet 121 and the output end 321 of the second microchannel; the first upper substrate 11, the first lower substrate 12, the second upper substrate 21, and the second lower substrate 22 are all made of stainless steel; the liquid inlet 111 and the liquid outlet 121 are both detachably connected to the filter 4; the width of the first microchannel 33 and the second microchannel 34 is 0.5 to 2 mm.

[0040] In this embodiment, the stainless steel material can prevent rust from occurring after contact with the solution, thereby contaminating the solution. On the other hand, the filter 4 can filter out impurities in the solution to prevent the solution from being mixed in a state containing impurities, thereby affecting the mixing effect. In addition, the filter 4 is detachable, which makes it convenient for the staff to maintain, clean and replace the filter 4. It should be noted that the width of the first microchannel 33 and the second microchannel 34 in this embodiment is 1.5 mm, but this is only an example choice of this embodiment. The specific width selection can be set according to actual conditions.

[0041] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
