[0002] A drug synthesis reactor is an important device used in the process of chemical drug synthesis, which can realize the synthesis of drug molecules on a laboratory or industrial scale. The design and operation of a drug synthesis reactor are crucial for improving synthesis efficiency, controlling product quality, and ensuring the safety of the production process.

[0003] Currently, most continuous flow drug synthesis reactors still use traditional mechanical stirring methods for mixing, making it difficult to utilize the properties of the liquid itself for mixing, resulting in greater difficulty in the subsequent cleaning work of the stirring device and increasing the maintenance cost; in addition, existing continuous flow reactors usually do not have the ability to flexibly select and switch different reagents for mixing.

[0004] Therefore, it is necessary to provide a regulation system for a continuous flow drug synthesis reactor to solve the problems in the above background art. Summary of the Utility Model

Through the cooperation of the flow channel of the conical platform and the injection nozzle, the pressure of the liquid supply is adjusted, so that the main base liquid and the reaction liquid are initially counter-jet mixed using the properties of the liquid itself, and then through the secondary flow mixing of the drug in the diversion holes on the baffle plate, the contact area between the reactants is increased, thereby accelerating the chemical reaction, facilitating the realization of efficient mixing between liquids, reducing the dependence on traditional stirring methods, and reducing the subsequent cleaning difficulty inside the reactor.

Detailed implementation manners

[0025] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings in the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0026] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features; in the description of the present application, unless otherwise specified, the meaning of "a plurality" is three or more.

[0027] Figures 1-5A continuous flow drug synthesis reactor control system provided by an embodiment of the present application includes: a reactor 1, a main liquid supply adjustment unit 4, and a secondary liquid supply adjustment unit 5. Among them, a main liquid inlet 2 is fixedly arranged at the upper end of the reactor 1, and the main liquid supply adjustment unit 4 is arranged at the upper end of the reactor 1. The secondary liquid supply adjustment unit 5 is arranged at the lower end inside the reactor 1. The main liquid supply adjustment unit 4 includes a servo motor 41 fixed to the upper end of the reactor 1. The output end of the servo motor 41 is fixedly provided with a rotating rod 42. A conical platform 44 is fixedly arranged at the lower end of the rotating rod 42. An expansion adjustment cylinder 43 is fixedly arranged inside the rotating rod 42. The output end of the expansion adjustment cylinder 43 is fixed with a flow isolation component 45. Four inclined flow channels 441 are uniformly arranged inside the conical platform 44. The flow channels 441 are communicated with the main liquid inlet 2. The secondary liquid supply adjustment unit 5 includes a guide seat 51 fixedly arranged at the bottom end inside the reactor 1. Four uniformly distributed injection nozzles 52 are fixedly arranged on the guide seat 51. The number and positions of the flow channels 441 and the injection nozzles 52 correspond to each other. And each injection nozzle 52 is communicated with its corresponding secondary liquid supply mechanism.

[0028] Based on the above technical solution, first, the main base liquid is supplied into the flow channels 441 through the main liquid inlet 2. The operator selectively starts the gear of the servo motor 41 according to the requirements, which is divided into the following four situations:

[0029] When only one flow channel 441 is opened, the injection nozzle 52 corresponding to the opened flow channel 441 is communicated with the secondary liquid supply mechanism. At this time, the main base liquid at one outlet is preliminarily mixed with a reaction liquid in a counter-jet manner.

[0030] When only two flow channels 441 are opened, the injection nozzles 52 corresponding to the opened flow channels 441 are communicated with the secondary liquid supply mechanism. At this time, the main base liquid at two outlets is preliminarily mixed with two reaction liquids in a counter-jet manner.

[0031] When only three flow channels 441 are connected, the injection nozzles 52 corresponding to the opened flow channels 441 are communicated with the secondary liquid supply mechanism. At this time, the main base liquid at three outlets is preliminarily mixed with three reaction liquids in a counter-jet manner.

[0032] When all four flow channels 441 are opened, all the injection nozzles 52 are communicated with the secondary liquid supply mechanism. At this time, the main base liquid at four outlets is preliminarily mixed with four reaction liquids in a counter-jet manner.

[0033] On the basis of the above technical solution, through the cooperation of the flow channels 441 of the conical platform 44 and the injection nozzles 52, the main base liquid and the reaction liquid are preliminarily mixed in a counter-jet manner by using the properties of the liquid itself, which is beneficial to achieving efficient mixing between liquids, reducing the dependence on the traditional stirring method, and reducing the subsequent cleaning difficulty inside the reactor 1.

[0034] In a possible implementation manner, a heating unit 3 and a liquid outlet 8 are further installed on the reactor 1, and a support 7 is fixedly arranged at the lower end of the reactor 1, and the mixed liquid medicine is pumped out from the liquid outlet 8.

[0035] In a possible implementation manner, a main control unit is installed on the reactor 1. The main control unit is electrically connected to the main liquid supply adjustment unit 4 and the secondary liquid supply adjustment unit 5 respectively. Pressure adjustment units are arranged in both the main liquid supply adjustment unit 4 and the secondary liquid supply adjustment unit 5, and both the pressure adjustment unit and the heating unit 3 are electrically connected to the main control unit.

[0036] By adopting the above technical solution, the corresponding number of reaction liquids are selected according to actual needs and fed into the corresponding secondary liquid supply mechanisms. Then, the rotation of the servo motor 41 is controlled by the main control unit to adjust the opening of the corresponding number of flow channels 441 on the conical platform 44. The main control unit then controls the pressure adjustment unit to adjust the supply pressures of the main base liquid and the reaction liquid and the temperature of the heating unit 3 matching the reaction, so that the main base liquid and the reaction liquid react in the reactor 1.

[0037] In a possible implementation manner, a hollow chamber 421 and an annular chamber 422 are formed in the rotating rod 42. The telescopic adjustment cylinder 43 is fixedly arranged in the hollow chamber 421, and an output end of the telescopic adjustment cylinder 43 is fixed with a sliding rod 431. A flow isolation component 45 is fixedly arranged at the lowermost end of the sliding rod 431. One end of the annular chamber 422 is communicated with the main liquid inlet 2, and the other end of the annular chamber 422 is communicated with the flow channels 441.

[0038] By the above technical solution, when the flow isolation component 45 needs to rotate, the telescopic adjustment cylinder 43 controls the sliding rod 431 to extend, and the flow isolation component 45 moves away from the conical platform 44. Then, the servo motor 41 is started, and the flow isolation component 45 rotates. Then, the telescopic adjustment cylinder 43 contracts again, and the flow isolation component 45 fits with the conical platform 44, completing the opening and closing adjustment work of the flow channels 441 on the conical platform 44.

[0039] In a possible implementation manner, the flow isolation component 45 includes a soft cushion layer and a base layer. The soft cushion layer and the base layer have the same structure, and both include a rotating partition plate 451 fixed to the sliding rod 431. An installation hole 452 is provided at the center of the axis of the rotating partition plate 451. The rotating partition plate 451 is fixed to the sliding rod 431 through the installation hole 452. And through holes one 453, through holes two 454, through holes three 455, and through holes four 456 are evenly provided in the circumferential direction of the rotating partition plate 451. Through holes five 457, through holes six 458, and through holes seven 459 are evenly provided on the rotating partition plate 451 between the through holes one 453 and the through holes two 454. Through holes six 458 and through holes seven 459 are provided on the rotating partition plate 451 between the through holes two 454 and the through holes three 455. Through holes seven 459 are provided on the rotating partition plate 451 between the through holes three 455 and the through holes four 456. After the flow isolation component 45 rotates, under the contraction action of the telescopic adjusting cylinder 43, the soft cushion layer rises, and the rotating partition plate 451 can be attached to the lower surface of the conical platform 44, so as to block or open the flow channel 441.

[0040] In a possible implementation manner, the through holes one 453, the through holes two 454, the through holes three 455, and the through holes four 456 are all correspondingly arranged opposite to the outlet of the flow channel 441.

[0041] It should be noted that in the initial stage, the through holes one 453, the through holes two 454, the through holes three 455, and the through holes four 456 are all connected to the flow channel 441. Subsequently, the flow isolation component 45 can be selectively rotated according to actual needs, so as to adjust the opening or closing of each flow channel 441.

[0042] That is, in the initial stage, the through holes one 453, the through holes two 454, the through holes three 455, and the through holes four 456 are all connected to the flow channel 441. At this time, the main base liquid at the four outlets is initially mixed with the four reaction liquids in a counterflush manner; after the flow isolation component 45 rotates by 22.5°, the through holes five 457 are connected to the flow channel 441. At this time, the main base liquid at one outlet is initially mixed with one reaction liquid in a counterflush manner; after the flow isolation component 45 rotates by 45°, the through holes six 458 are connected to the flow channel 441. At this time, the main base liquid at two outlets is initially mixed with two reaction liquids in a counterflush manner; after the flow isolation component 45 rotates by 67.5°, the through holes seven 459 are connected to the flow channel 441. At this time, the main base liquid at three outlets is initially mixed with three reaction liquids in a counterflush manner, so that the reaction liquids at each outlet of the nozzle 52 can be initially mixed with the main base liquid at the outlet of each flow channel 441 in a counterflush manner.

[0043] In a possible implementation manner, the heating unit 3 includes a heating channel 31 fixedly arranged inside the reactor 1, and a plurality of flow blocking members 6 are installed on the heating channel 31. The flow blocking members 6 enable the liquid medicine after preliminary counter-jet mixing to perform secondary flow mixing.

[0044] It should be noted that the liquid medicine of preliminary counter-jet mixing is the mixture of the main base liquid and each reaction liquid, while the secondary flow mixing is for the flow mixing between the reaction liquids.

[0045] In a possible implementation manner, the flow blocking member 6 includes a flow blocking plate 61 fixedly arranged with the heating channel 31 respectively. A central hole 62 is opened at the center of the flow blocking plate 61, and a plurality of longitudinally distributed diversion holes 63 are opened in half of the area of the flow blocking plate 61. The central hole 62 is fixedly arranged with the guide seat 51.

[0046] Adopting the above technical solution, the flow blocking plate 61 with the diversion holes 63 opened is the opening area, and the flow blocking plate 61 without the diversion holes 63 opened is the non-opening area. The opening areas of the upper flow blocking plates 61 are correspondingly arranged with the non-opening areas of the lower flow blocking plates 61. The liquid medicine after preliminary counter-jet mixing falls at the uppermost flow blocking plate 61. At this time, the liquid medicine is on the flow blocking plate 61 and can fall into the non-opening area of the next flow blocking plate 61 from top to bottom along the diversion holes 63. Then the liquid medicine enters the diversion holes 63 in the opening area along the non-opening area of the flow blocking plate 61 and falls to the bottom of the reactor 1, enabling the liquid medicine to perform secondary flow mixing. Finally, the liquid medicine that has completed two mixings is pumped out from the liquid outlet 8.

[0047] Based on the above technical solution, the secondary flow mixing of the medicine in the diversion holes 63 of the flow blocking plate 61 increases the contact area between the reactants, thereby accelerating the chemical reaction between the reactants. Through the cooperation of the flow channel 441 and the flow isolation assembly 45, the start and stop of the supply of the main base liquid into the reactor 1 can be adjusted and switched, and the corresponding spray nozzles 52 at the corresponding positions can be selectively used, so that the main base liquid can be flexibly switched to be mixed with different medicaments, and multiple secondary liquid supply mechanisms can also be operated in parallel, facilitating multi-step synthesis reactions.

[0048] Working principle:

[0049] The operator first determines the start, stop and adjustment operations of the heating unit 3, and then supplies the main base liquid into the flow channel 441 through the main liquid inlet 2. The operator selectively starts the gears of the servo motor 41 according to the requirements, which are divided into the following four situations:

[0050] When the through hole five 457 is connected to the corresponding flow channel 441 and the other flow channels 441 are all closed, the spray nozzle 52 corresponding to the opened flow channel 441 is connected to the secondary liquid supply mechanism, and the pressure adjustment unit is started. The main base liquid at one outlet is preliminarily mixed with a reaction liquid in a counter-jet manner;

[0051] When the through hole six 458 communicates with the corresponding flow channel 441 and the other flow channels 441 are all closed, the injection nozzle 52 corresponding to the opened flow channel 441 communicates with the secondary liquid supply mechanism, and the pressure regulating unit is started, and the main base liquid at the two outlets and the two reaction liquids are subjected to a preliminary mixing in a counter-jet manner;

[0052] When the through hole seven 459 communicates with the corresponding flow channel 441 and the other flow channels 441 are closed, the injection nozzle 52 corresponding to the opened flow channel 441 communicates with the secondary liquid supply mechanism, and the pressure regulating unit is started, and the main base liquid at the three outlets and the three reaction liquids are subjected to a preliminary mixing in a counter-jet manner;

[0053] When the through hole one 453, the through hole two 454, the through hole three 455, and the through hole four 456 all communicate with the flow channel 441, the injection nozzles 52 all communicate with the secondary liquid supply mechanism, and the pressure regulating unit is started, and the main base liquid at the four outlets and the four reaction liquids are subjected to a preliminary mixing in a counter-jet manner;

[0054] The liquid medicine after the preliminary mixing falls to the baffle plate 61. At this time, the liquid medicine flows downward along the diversion holes 63 for secondary flow mixing, and the liquid medicine after the two-time mixing is pumped out from the liquid outlet 8.

[0055] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. The present application is not limited to the exact structures already described and illustrated in the drawings, and it cannot be considered that the specific implementation of the present application is only limited to these descriptions. For those of ordinary skill in the technical field to which the present application belongs, without departing from the concept of the present application, various changes and deformations made should be regarded as belonging to the protection scope of the present application.
