This fine chemical synthesis reactor with uniform mixing can quantitatively feed different raw materials, and evenly mix the fine materials through compressed air and the stirring rod.

[0005] In the above-mentioned technology and existing chemical synthesis reactors, the mixing of chemicals in the reactor cavity is usually achieved by rotating the stirring blades. However, this traditional mixing method has the following significant defects: 1. Restriction on material flow: Traditional stirring methods rely on mechanical force to drive fluid movement, which cannot effectively overcome the flow resistance caused by viscosity and density differences of materials. The material flow pattern is single and cannot break through the static flow restriction, resulting in low mixing efficiency, affecting the reaction rate and product quality; 2. Limited mixing efficiency: The stirring blades can only generate shear force and turbulence in a local area, making it difficult to achieve uniform mixing of the entire reactor cavity, especially in high-viscosity or non-Newtonian fluids, where the mixing efficiency is significantly reduced; 3. Blind spot problem of stirring: The stirring blades cannot completely cover the inner wall and bottom area of ​​the reactor during rotation, causing the material to accumulate in the dead corner, forming a mixing blind spot, affecting the reaction uniformity and product quality. It takes a long time and continuous stirring to achieve comprehensive stirring and mixing of the materials in the reactor cavity, which consumes a lot of energy and time.

[0006] In summary, the existing chemical synthesis reactors simply rely on stirring blades to achieve mixing, which has problems such as material flow restriction, limited mixing efficiency, and stirring blind spots, resulting in low efficiency of compound synthesis in the reactor and high energy consumption in the synthesis process.

A discharge port is provided at the bottom end of the reactor body, and a support platform is provided on the side wall of the reactor body.

[0017] Compared with the prior art, the multifunctional chemical synthesis reactor of the present invention has the following beneficial effects: 1. In view of the problem that the existing chemical synthesis reactor relies on the traditional stirring method and mainly relies on mechanical force to drive the movement of fluid, which cannot effectively overcome the flow resistance caused by the viscosity and density differences of the materials, and the material flow pattern is single and cannot break through the static flow restriction, resulting in low mixing efficiency, affecting the reaction rate and product quality, the present invention sets a vacuum space in the reaction chamber structure of the reactor, and accurately changes the vacuum pressure environment of the chemical reaction area below the pressure regulating plate through the reciprocating lifting and lowering movement of the pressure regulating plate component. This process forms a regular contraction mechanism, so that the chemicals can be dynamically mixed under different pressure environments. Specifically, the present invention greatly enhances the mixing efficiency of the fluid through periodic vacuum pressure changes with the help of the regular contraction mechanism, and successfully breaks through the inherent limitations of the traditional static vacuum system on the material flow. Compared with the traditional method of relying solely on mechanical stirring to achieve fluid mixing, the vacuum pressure change of the present invention can penetrate deeply into the materials with viscosity or density differences, effectively prompting the materials to break through the constraints of static flow; Second, in view of the problem that the existing stirring blades can only generate shear force and turbulence in local areas, and it is difficult to achieve uniform mixing of the entire inner cavity of the reactor, especially in high-viscosity or non-Newtonian fluids, the mixing efficiency is significantly reduced. On the basis of providing a stirring paddle, the present invention combines regular vacuum pressure changes to achieve the dual synergistic effect of mechanical mixing of materials and mixing with vacuum pressure changes. Specifically, the present invention combines this vacuum pressure change mixing method with a rotating stirring paddle component to achieve the dual synergistic effect of mechanical mixing of materials and mixing with vacuum pressure changes. This dual effect not only significantly accelerates the reaction rate of chemical synthesis, but also can more finely and comprehensively guarantee the product quality after chemical synthesis, and realize the multifunctional application of chemical synthesis; 3. The existing stirring blades cannot completely cover the inner wall and bottom area of ​​the reactor during rotation, resulting in accumulation of materials in dead corners, forming mixing blind spots, affecting reaction uniformity and product quality. A long period of continuous stirring is required to achieve comprehensive stirring and mixing of materials in the reactor cavity, which consumes a lot of energy and time. The present invention can perform comprehensive mixing on the reaction area below the pressure regulating plate indiscriminately and in all directions, and drive the materials to fully flow and mix in the reaction area through periodic changes in vacuum pressure, successfully solving the problem of covering dead corners that is prone to occur in traditional mechanical stirring methods that rely solely on stirring blades, avoiding the adverse effects of material accumulation in mixing blind spots and mixing dead corners on reaction uniformity and mixing quality, significantly improving mixing efficiency, greatly shortening the overall time required for the reaction, reducing energy consumption caused by long-term stirring, and providing a more efficient production model for chemical synthesis; 4. In the traditional way, if two different mixing mechanisms of mechanical stirring and vacuum pressure change mixing are to be realized, it is usually necessary to configure multiple independent power systems, which invisibly increases the equipment cost and energy consumption. In the present invention, the power source used to drive the stirring paddle of the component to rotate circumferentially to realize mechanical stirring and mixing is the same power source as the power source used to drive the pressure regulating plate of the component to perform lifting and reciprocating motion to achieve vacuum pressure change mixing. That is, the present invention achieves dual effects through a single power source, reduces the complexity of the power system and the overall cost of the equipment, reduces energy consumption, improves energy utilization efficiency, and the unified driving force can accurately ensure the two mechanisms of mechanical stirring and vacuum pressure change mixing. The synchronization of the action timing, mechanical stirring and vacuum pressure change mixing complement each other in promoting the material mixing process. The synchronous action can make the material experience both the stirring effect of mechanical force and the flow and mixing effect brought by pressure change at the same time, avoiding the problem of inconsistent mixing timing caused by the difference in the start-up and operation time of different power sources, thereby achieving more efficient and uniform material mixing, which is helpful to improve the chemical reaction rate and the stability of product quality; in addition, due to the reduction of the power system, the number of parts that need to be maintained and repaired is correspondingly reduced, which reduces the probability of failure and the maintenance workload, improves the reliability and service life of the equipment, and further enhances the advantages of the present invention in practical applications; 5. In the present invention, a cylinder and a first slideway are arranged on the stirring shaft, and the lifting and reciprocating movement of the pressure regulating plate can be realized in cooperation with the first ball, and the circumferential rotation is converted into the lifting and reciprocating movement in the vertical direction, thereby achieving the purpose of vacuum pressure change mixing. At the same time, the bottom end of the stirring shaft is connected to the stirring paddle, which can ensure the normal application of the stirring paddle for mechanical stirring and mixing. The present invention combines the vacuum pressure change mixing method based on the lifting and reciprocating movement of the pressure regulating plate with the mechanical stirring and mixing method of the stirring paddle, and promotes the chemicals in the reactor to react fully and effectively from different levels and angles, providing a strong guarantee for improving the chemical reaction rate and product quality stability; 6. In the present invention, the vertical distance between the highest point of the inner cavity of the first slide and the lowest point thereof is smaller than the vertical distance between the highest point of the inner cavity of the second slide and the lowest point thereof, that is, the present invention is provided with two groups of different slides on the cylinder, and the first ball and the second ball are respectively provided at corresponding positions, and the first slide and the first ball cooperate to realize the relatively small lifting and reciprocating movement of the pressure regulating plate, so as to promote the small-scale change of the vacuum environment pressure below the pressure regulating plate, and the second slide and the second ball cooperate to realize the relatively large lifting and reciprocating movement of the pressure regulating plate, so as to promote the large-scale change of the vacuum environment pressure below the pressure regulating plate, that is, the present invention can flexibly adjust the lifting and lowering amplitude of the pressure regulating plate, and flexibly adjust the pressure change range of the vacuum environment according to the synthesis requirements of chemicals of different properties, and can provide highly adapted reaction conditions for chemical synthesis in a multifunctional and diversified manner, and effectively improve the efficiency of the synthesis reaction and the product quality; 7. The present invention has a functional module for adjusting the relative position of the first ball and the second ball. By rotating the component driving plate, one of the first ball and the second ball can be put into working state and the other can be switched to inactive state, ensuring that the two can be switched between the active state and the inactive state normally and stably, meeting the use requirements under different working conditions and improving the flexibility and adaptability of the equipment operation; 8. The present invention can realize the relative adjustment of the positions of the first ball and the second ball at one time through the linkage of the cylinder, the rotating shaft, the driving plate, the first slide groove and the second slide groove, that is, the present invention does not need to adopt the complicated operation of driving the first ball and the second ball to move separately in steps, which greatly simplifies the adjustment process, improves the adjustment efficiency, and enhances the continuity and stability of the equipment operation; 9. In the present invention, when the first ball is about to leave the first slide cavity, the second ball is just embedded in the second slide cavity, which means that in the process of adjusting the position of the first ball and the second ball, there is a transition state, that is, the first ball is still embedded in the first slide cavity, while the second ball has entered the second slide cavity, thereby ensuring that when the first ball and the second ball are selectively used, the connection between the pressure regulating plate and the cylinder is always stable, effectively avoiding the risk of the pressure regulating plate falling off from the cylinder, and ensuring the safety and stability of the equipment operation; 10. In the present invention, a top plate is arranged above the inner cavity of the reaction chamber. When the pressure regulating plate reciprocates in the vertical direction in the inner cavity of the reaction chamber to adjust the vacuum pressure change, it can still ensure that the space between the top plate and the reaction chamber maintains a vacuum state, which provides a reliable guarantee for the reaction of chemicals in a vacuum environment, avoids the interference of external factors on the chemical reaction, and is conducive to improving the efficiency of the chemical reaction and the purity of the product; 11. In the present invention, a bellows airbag and a sealing sleeve are specially added. The bellows airbag has the ability to expand and contract, and can closely follow the lifting and moving of the pressure regulating plate and move synchronously in the corresponding direction. The setting of the sealing sleeve not only ensures that the stirring shaft and the bellows airbag can be rotatably connected, but also ensures the sealing of the connection. Through this structural design, it is further ensured that the upper and lower parts of the pressure regulating plate can be maintained in a vacuum state. When the pressure regulating plate is lifted and moved, the pressure of the chemical reaction area below it can be accurately and effectively adjusted, which provides a solid and reliable technical support for the reaction of chemicals under a specific vacuum pressure environment, and effectively ensures the efficient progress of chemical reactions and the stability of product quality. 12. The present invention realizes flexible and precise control of the connection state between the reaction chamber and the second connection chamber by setting the first connection chamber and the solenoid valve. In the actual operation process, when the first connection chamber is in a closed state, it can effectively block the connection between the reaction chamber and the second connection chamber of the external environment, ensuring that the inside of the reaction chamber maintains a closed vacuum environment. In this environment, the two functions of mechanical mixing and vacuum pressure change mixing possessed by the present invention can be stably operated, providing good conditions for the full mixing and reaction of chemicals; when the first connection chamber is in an open state, the reaction chamber and the second connection chamber are connected, and the fully mixed chemicals can flow smoothly downward and enter the subsequent process steps, thereby effectively integrating the reaction and subsequent processing processes, ensuring the stability of the reaction environment, and improving the consistency and efficiency of the production process, meeting the needs of different operating states in actual production; 13. The present invention arranges multiple groups of flow-blocking columns equidistantly around the inner cavity of the second connecting tube, which can impact and guide the chemicals falling from the top, promote the chemicals to enter the subsequent process in a dispersed manner, realize multi-angle impact and dispersion of the chemicals, and provide further mixing for the synthesis of the chemicals. That is, the present invention arranges multiple groups of flow-blocking columns, which can make the various components of the chemicals contact more fully, create more favorable conditions for the synthesis reaction of the chemicals, help improve the efficiency of the chemical reaction and the quality of the product, and effectively improve the performance of the entire synthesis process; 14. In the present invention, a vertical recess, a first inclined recess, and a second inclined recess are arranged in each group of flow-blocking columns. The above components provide multi-angle flow paths for chemicals during the falling process. In the process of continuously changing the flow direction, the chemicals achieve multi-angle collision and mixing in the inner cavity of the second connecting cylinder. Each change in direction increases the probability of collision between the chemicals and the surfaces of different components, as well as the opportunity for mutual contact between different components, thereby further improving the uniformity of chemical synthesis, effectively optimizing the reaction conditions of chemical synthesis, and helping to improve product quality and reaction efficiency; 15. In the present invention, the obstruction columns corresponding to the upper and lower groups are arranged in a staggered manner. When the chemical flows downward from the upper obstruction column to the lower obstruction column, this staggered layout can further force the chemical to change its direction of travel by virtue of its unique spatial structure. The change in the direction of travel of the chemical allows it to contact more reaction spaces and components at different positions during the flow process, thereby increasing the chances of mutual mixing and collision between the various components of the chemical, effectively promoting the uniformity of chemical synthesis, and providing an important guarantee for improving the efficiency of chemical reactions and product quality; 16. In the present invention, a spiral guide channel is provided to promote the formation of a spiral flow structure of chemicals in the spiral guide channel, forming a multi-level and multi-scale vortex structure, promoting the formation of a strong turbulent effect of chemicals in the spiral guide channel, ensuring that the chemical fluid generates complex shear force and pressure gradient during the rotation process, so as to achieve further mixing of chemicals in the spiral guide channel; 17. In the design framework of the present invention, the diameter of the connecting point between the spiral guide channel and the second connecting cylinder is larger than the diameter of the output end at the bottom of the spiral guide channel, so that the spiral guide channel presents a unique shape of being wide at the top and narrow at the bottom. After the chemical enters the lower spiral from the upper spiral of the spiral guide channel, its rotation radius decreases accordingly, which causes the chemical to gradually increase its speed in the inner cavity of the spiral guide channel. The high-speed moving chemical produces a strong impact on the inner wall of the spiral guide channel. During the impact process, the components inside the chemical are further dispersed and mixed, forming a more efficient mixing effect, which provides strong support for improving the reaction efficiency and product uniformity of chemical synthesis; 18. In the present invention, on the basis of adopting a spiral flow guide channel with a shape of being wide at the top and narrow at the bottom, a plurality of S-shaped flow guide components are arranged on the inner side wall of the spiral flow guide channel, and these flow guide components are symmetrically distributed on the inner side wall of the spiral flow guide channel. When the chemical fluid flows through the spiral flow guide channel, the S-shaped flow guide components can induce turbulence. At the same time, under the unique guiding effect of the flow guide components, the chemical fluid is forced to move along the arc-shaped side wall of the flow guide components. This moving mode causes the chemical fluids at the two corresponding groups of flow guide components to collide with each other, thereby further enhancing the mixing effect of the chemicals and improving the uniformity and efficiency of the chemical reaction. 19. Since the inner cavity of the spiral guide channel is set to a gradually changing shape with a width at the top and a narrowness at the bottom, the speed of the chemicals moving along the spiral guide channel gradually increases. Therefore, the chemicals at different positions in the spiral guide channel will collide with the guide components at different positions, and the collision speeds are different. This collision phenomenon with speed differences makes the chemicals produce a variety of mixing effects during the collision process. The irregular speed change provides a more complex and changeable fluid mechanics environment for the mixing of chemicals. Compared with the traditional regular flow, this irregular speed travel mode can promote more sufficient contact, friction and mixing between chemicals, thereby further improving the mixing uniformity of chemicals and creating favorable conditions for the efficient conduct of chemical reactions and the improvement of product quality. 20. The present invention integrates multiple functions such as mechanical mixing, vacuum pressure change mixing, flow resistance collision mixing, spiral mixing, and flow diversion mixing to achieve multiple mixing effects on chemicals. The above-mentioned multifunctional mixing method can achieve full, uniform, and high-quality mixing effects of chemicals from multiple dimensions and levels; In summary, the present invention aims at the limitations of traditional chemical synthesis reactors, adopts vacuum space and dynamic pressure change mechanism, realizes periodic vacuum pressure change through reciprocating lifting, effectively breaks through the static flow limitation of materials, deeply acts on materials with different viscosities and densities, solves the problems of uneven mixing and dead corners, combines mechanical stirring to achieve double synergistic mixing, significantly improves mixing efficiency and uniformity, accelerates the reaction process and ensures product quality; in terms of power system design, a single power source is used to drive two mixing mechanisms, which reduces costs and energy consumption, ensures the synchronization of the two action timings, reduces maintenance workload, and improves equipment reliability and service life; the component design and layout are sophisticated, realizing lifting and moving conversion, and flexible The pressure change range is adjusted to adapt to different synthesis needs, key components are guaranteed to be firmly connected, and a vacuum environment is maintained. Special components impact, divert, break up and mix chemicals, and use unique structures to cause chemicals to form complex flow structures and turbulence, further enhancing the mixing effect. By precisely controlling the connectivity state, the reaction and subsequent processing procedures are effectively integrated to improve production consistency and efficiency, providing a more efficient and stable solution for chemical synthesis. The use of mechanical mixing, vacuum pressure change mixing, choke collision mixing, spiral mixing, diversion mixing and other multifunctional mixing methods can achieve full, uniform and high-quality mixing of chemicals from multiple dimensions and levels.

A discharge port 8 is provided at the bottom end of the reactor body 1, and the finished chemicals after the reaction can be discharged to the outside through the opened discharge port 8. A support platform 9 is provided on the side wall of the reactor body 1. The support platform 9 ensures that there is enough space between the reactor body 1 and the ground, and at the same time provides effective guarantee for the subsequent discharge port 8 to discharge materials to the outside.

[0021] By reciprocating the lifting and lowering movement of the pressure regulating plate 4004, the vacuum pressure environment of the chemical reaction area below the pressure regulating plate 4004 is accurately changed. This process forms a regular contraction mechanism, which enables the chemicals to be dynamically mixed under different pressure environments. Specifically, the present invention, with the help of this regular contraction mechanism, greatly enhances the mixing efficiency of the fluid through periodic vacuum pressure changes, and successfully breaks through the inherent limitations of the traditional static vacuum system on the flow of materials. Compared with the traditional method of relying solely on mechanical stirring to achieve fluid mixing, the vacuum pressure change of the present invention can penetrate deeply into the interior of materials with viscosity or density differences, effectively prompting the materials to break through the constraints of static flow; in addition, the present invention combines this vacuum pressure change mixing method with the rotating stirring paddle 4031 component to achieve mechanical mixing of materials and vacuum. The dual synergistic effect of pressure change and mixing not only significantly accelerates the reaction rate of chemical synthesis, but also can more finely and comprehensively guarantee the product quality after chemical synthesis, thereby realizing the multifunctional application of chemical synthesis; in addition, the present invention can indiscriminately and comprehensively mix the reaction area below the pressure regulating plate 4004, and drive the materials to fully flow and mix in the reaction area through periodic vacuum pressure changes, thereby successfully solving the problem of dead angle coverage that is prone to occur in the traditional mechanical stirring method that relies solely on stirring blades, avoiding the adverse effects of material accumulation in mixing blind spots and mixing dead corners on reaction uniformity and mixing quality, significantly improving mixing efficiency, greatly shortening the overall time required for the reaction, and reducing the energy consumption caused by long-term stirring, thereby providing a more efficient production model for chemical synthesis.

[0022] Specifically, the specific working principle of the vacuum pressure change mixing method is mainly due to the fact that when the vacuum pressure in the reaction chamber 4001 changes periodically, a pressure difference will be generated in different areas. Under the action of the pressure difference, the fluid flows from a high pressure area to a low pressure area. For example, when the pressure in the reaction area below the pressure regulating plate 4004 decreases to form a relatively low pressure area, the material in the surrounding higher pressure area will flow to the low pressure area. This flow breaks the original relatively static or single flow state of the material and prompts the material to start mixing. In addition, the pressure change will cause the material itself to compress and expand. When the pressure increases, the material is compressed, the density increases, and the pressure When the pressure is reduced, the material expands and the density decreases. This change in density will cause the distribution of the material at different positions to change, causing materials with different densities or layers to interpenetrate and mix with each other. In addition, the periodic change in vacuum pressure provides additional energy and driving force for the molecules, intensifies the thermal motion of the molecules, accelerates the diffusion rate between molecules, and allows molecules of different components to penetrate and mix with each other more quickly, thereby improving the degree of mixing of the materials at the microscopic level. In summary, the present invention can assist the stirring paddle 4031 in accelerating the dynamic mixing of chemicals by regularly changing the vacuum pressure of the reaction environment in the inner cavity of the reaction chamber 4001.

[0023] Specifically, refer mainly to Figures 5 to 9 As shown, a cylinder 4008 is fixedly installed on the stirring shaft 4003. A first slideway 4009 and a second slideway 4010 are respectively provided on the cylinder 4008. Both the first slideway 4009 and the second slideway 4010 are inclined. A first ball 4017 is embedded in the inner cavity of the first slideway 4009, and a second ball 4020 is embedded in the inner cavity of the second slideway 4010. Among them, the positional relationship between the first ball 4017 and the second ball 4020 is divided into a first state and a second state. In the first state, the first ball 4017 is inserted into the inner cavity of the first slideway 4009, and the second ball 4020 is separated from the inner cavity of the second slideway 4010. At this time, by rotating the cylinder 4008, the first ball 4017 can be driven to drive the pressure regulating plate 4004 to perform reciprocating vertical movement. In the second state, the second ball 4020 is inserted into the inner cavity of the second slideway 4010, and the first ball 4017 is separated from the inner cavity of the first slideway 4009. At this time, by rotating the cylinder 4008, the second ball 4020 can be driven to drive the pressure regulating plate 4004 to perform reciprocating vertical movement. Specifically, the vertical distance from the highest point to the lowest point in the inner cavity of the first slideway 4009 is less than the vertical distance from the highest point to the lowest point in the inner cavity of the second slideway 4010. When the pressure regulating plate 4004 moves up and down, the vacuum pressure in the reaction space below it can be accurately adjusted. By controlling the moving amplitude of the pressure regulating plate 4004, precise control of the vacuum pressure in the reaction space can be achieved, providing a stable and suitable pressure environment for chemical reactions, and specifically improving the reaction efficiency and product quality. That is, in the present invention, two different slideways are provided on the cylinder 4008, and the first ball 4017 and the second ball 4020 are respectively arranged at corresponding positions. Through the cooperation of the first slideway 4009 and the first ball 4017, the pressure regulating plate 4004 can be driven to perform relatively small-amplitude reciprocating up and down movement, so as to cause a relatively small-amplitude change in the vacuum environment pressure below the pressure regulating plate 4004. Through the cooperation of the second slideway 4010 and the second ball 4020, the pressure regulating plate 4004 can be driven to perform relatively large-amplitude reciprocating up and down movement, so as to cause a relatively large-amplitude change in the vacuum environment pressure below the pressure regulating plate 4004. That is, the present invention can flexibly adjust the lifting amplitude of the pressure regulating plate 4004, flexibly adjust the pressure change range of the vacuum environment according to the synthesis requirements of different properties of chemical products, and can provide highly adaptable reaction conditions for chemical product synthesis in a multi-functional and diverse manner, effectively improving the efficiency of the synthesis reaction and the product quality.

[0025] Main references Figures 9 to 11 As shown, the first state and the second state are adjusted by an adjustment mechanism; the adjustment mechanism includes a blind groove 4005 opened on the upper surface of the pressure adjustment plate 4004, and also includes two support plates 4011 fixedly installed on the upper surface of the pressure adjustment plate 4004, and a limiting column 4012 is fixedly installed between the two support plates 4011. The limiting column 4012 is respectively slidably sleeved with a first movable frame 4013 and a second movable frame 4018. The side wall of the first movable frame 4013 is installed with a first mounting seat 4014, and the first mounting seat A first driving pin 4015 is vertically mounted in the seat 4014, a first connecting rod 4016 is mounted at the bottom of the first moving frame 4013, a second mounting seat 4021 is mounted on the side wall of the second moving frame 4018, a second connecting rod 4019 is mounted at the bottom of the second moving frame 4018, and a second driving pin 4022 is vertically mounted in the second mounting seat 4021; wherein, a first ball 4017 is rollably embedded in the end of the first connecting rod 4016, and a second ball 4020 is rollably embedded in the end of the second connecting rod 4019; Specifically, when the first moving frame 4013 and the second moving frame 4018 move toward each other, the first ball 4017 is separated from the inner cavity of the first slide 4009, and the second ball 4020 is inserted into the inner cavity of the second slide 4010, that is, the second ball 4020 is connected to the cylinder 4008, thereby realizing that the later vertical movement interval of the pressure regulating plate 4004 is the interval of the vertical distance opened by the second slide 4010; when the first moving frame 4013 and the second moving frame 4018 move away from each other, the first ball 4017 is inserted into the first slide 4 009 cavity, the second ball 4020 is urged to detach from the second slide 4010 cavity, that is, the connection between the first ball 4017 and the cylinder 4008 is realized, thereby realizing that the later vertical movement range of the pressure regulating plate 4004 is the interval of the vertical distance opened by the first slide 4009; that is, when the first ball 4017 or the second ball 4020 selectively forms a connection relationship with the cylinder 4008, the lifting and lowering amplitude of the pressure regulating plate 4004 can be flexibly adjusted, so as to flexibly adjust the pressure change range of the vacuum environment according to the synthesis requirements of chemicals of different properties.

[0026] Main references Fig.10 and Fig.11 As shown, the adjustment mechanism also includes a rotating shaft 4023 vertically mounted on the bottom end of the limiting column 4012, the bottom end of the rotating shaft 4023 is rotatably connected to a driving plate 4024 through a bearing, and the two ends of the driving plate 4024 are respectively provided with a first slide groove 4025 and a second slide groove 4026, and the adjustment mechanism also includes a support frame 4027 fixedly mounted on the upper surface of the pressure regulating plate 4004, a cylinder 4028 is mounted on the support frame 4027, and the output end of the cylinder 4028 is fixedly connected to the second driving pin 4022; wherein, the first driving pin 4015 is slidably embedded in the inner cavity of the first slide groove 4025, and the second driving pin 4022 is slidably embedded in the inner cavity of the second slide groove 4026; The second driving pin 4022 is driven to move along the inner cavity of the second slide groove 4026 by the opened cylinder 4028, so that the second mounting seat 4021 drives the second moving frame 4018 to move along the outer wall of the limiting column 4012. At the same time, since the driving plate 4024 is rotatably connected with the rotating shaft 4023, when the moving second driving pin 4022 moves, the driving plate 4024 is driven to rotate around the rotating shaft 4023, so as to drive the first driving pin 4015 to move along the first slide groove 4025, so as to drive the first mounting seat 4014 to drive the first moving frame 4013 to move along the limiting column 4012. The outer wall moves, that is, the first movable frame 4013 and the second movable frame 4018 move synchronously along the outer wall of the limiting column 4012, the moving first mounting seat 4014 prompts the first ball 4017 connected to the end of the first connecting rod 4016 to insert into or disengage from the inner cavity of the first slide 4009, and the moving second movable frame 4018 prompts the second ball 4020 connected to the end of the second connecting rod 4019 to disengage from or insert into the inner cavity of the second slide 4010, thereby adjusting one of the first ball 4017 or the second ball 4020 to a state of connection with the cylinder 4008.

[0027] The specific process of the mixing reaction of chemicals in the coordinated reaction unit 4 is as follows: the chemicals to be reacted are put into the inner cavity of the reaction chamber 4001 through the feed port 7, and the stirring shaft 4003 and the stirring paddle 4031 are driven by the turned-on motor 3 to rotate circumferentially, so as to mechanically mix the chemicals in the inner cavity of the reaction chamber 4001 with the help of the rotation of the stirring paddle 4031; at the same time, the rotating stirring shaft 4003 drives the rotation of the cylinder 4008 to promote the synchronous rotation of the first slide 4009 and the second slide 4010, so as to promote the first ball 4017 or the second ball 4020 connected to the cylinder 4008 to move along the corresponding channel. There is a height difference, so the circumferentially rotating cylinder 4008 can prompt the first ball 4017 or the second ball 4020 connected thereto to reciprocate in the vertical direction. Under the limiting and guiding action of the slider 4006 and the guide groove 4007, the pressure regulating plate 4004 can reciprocate in the vertical direction in the reaction chamber 4001. Since the reaction chamber 4001 and the area below the pressure regulating plate 4004 are both vacuum spaces, the pressure regulating plate 4004 that moves up and down and reciprocates can achieve regular vacuum pressure changes in the reaction area of ​​the reactants below the pressure regulating plate 4004. Combined with the mechanical rotation and mixing of the stirring paddle 4031, the dual synergistic effect of mechanical mixing of materials and vacuum pressure change mixing is achieved, thereby accelerating the reaction rate of chemical synthesis.

[0028] Main references Fig. 9As shown, a corrugated airbag 4029 is installed in the middle of the bottom end of the pressure regulating plate 4004, and a sealing sleeve 4030 is installed in the middle of the bottom end of the corrugated airbag 4029. The stirring shaft 4003 penetrates the sealing sleeve 4030 in the vertical direction and is rotatably connected with the sealing sleeve 4030. The movement of the pressure regulating plate 4004 in the vertical direction will compress the corrugated airbag 4029. Sealing measures are provided here to effectively ensure that the connection between the pressure regulating plate 4004 and the corrugated airbag 4029 and the connection between the corrugated airbag 4029 and the sealing sleeve 4030 have good sealing properties. In the process of the corrugated airbag 4029 being compressed, this sealing performance will not be affected, thereby preventing external gas from entering or internal gas from leaking. In addition, the main reference Figure 4 As shown, a first connecting cylinder 4032 is installed in the middle of the bottom end of the reaction chamber 4001, and a solenoid valve 4033 is provided on the side wall of the first connecting cylinder 4032. After the chemicals react in the inner cavity of the reaction chamber 4001, the opened solenoid valve 4033 forms a discharge channel to enable the chemicals to flow to the next process.

[0029] Main references Figures 4 to 6 , Figure 12 to Figure 14 As shown, the bottom end of the first connecting tube 4032 is connected to the first auxiliary reaction unit 5; the first auxiliary reaction unit 5 includes a second connecting tube 5001, and a plurality of groups of flow blocking columns 5002 are arranged in the circumferential direction in the second connecting tube 5001, and each flow blocking column 5002 is respectively provided with a vertical recessed portion 5003, a first inclined recessed portion 5004 and a second inclined recessed portion 5005 on a side away from the inner side wall of the second connecting tube 5001, and the first inclined recessed portion 5004, the vertical recessed portion 5003 and the second inclined recessed portion 5005 form a recessed guide groove body with inclined ends and a vertical middle portion; wherein, the second connecting tube 500 1 is connected to the first connecting cylinder 4032, and the vertical recess 5003, the first inclined recess 5004, and the second inclined recess 5005 realize the diversification and irregularity of the new entry path of the chemical, providing a multi-angle flow path for the chemical in the falling process. In the process of continuously changing the flow direction, the chemical realizes multi-angle collision and mixing in the inner cavity of the second connecting cylinder 5001. Each change in direction increases the probability of collision between the chemical and the surface of different components, as well as the mutual contact between different components, thereby further improving the uniformity of chemical synthesis; in addition, mainly refer to Fig.14As shown, there are multiple groups of obstruction columns 5002 stacked up and down, and the upper and lower groups of obstruction columns 5002 are staggered; the chemicals enter the inner cavity of the second connecting tube 5001 downward through the first connecting tube 4032. Since there are multiple groups of obstruction columns 5002 circumferentially arranged in the inner cavity of the second connecting tube 5001, the chemicals are forced to change the direction of travel in the inner cavity of the second connecting tube 5001. The obstruction columns 5002 corresponding to the upper and lower groups are staggered. When the chemicals flow downward from the upper obstruction column 5002 to the lower obstruction column 5002, the chemicals are further forced to change their direction of travel, thereby impacting and guiding the chemicals falling from the top, prompting the chemicals to disperse into the subsequent process, thereby realizing multi-angle impact and dispersion of the chemicals.

[0030] Main references Fig.15 and Fig.16 As shown, the second auxiliary reaction unit 6 is connected to the bottom of the second connecting cylinder 5001; the second auxiliary reaction unit 6 includes a spiral guide channel 6001 connected to the bottom of the second connecting cylinder 5001, and the spiral guide channel 6001 is set in a spiral shape, which can promote the chemical to form a spiral flow structure in the spiral guide channel 6001, forming a multi-level and multi-scale vortex structure, and promoting the chemical to form a strong turbulent effect in the spiral guide channel 6001, ensuring that the chemical fluid generates complex shear force and pressure gradient during the rotation process, so as to achieve further mixing of the chemical in the spiral guide channel 6001, and the diameter of the connection between the spiral guide channel 6001 and the second connecting cylinder 5001 is larger than the diameter of the output end of the bottom end of the spiral guide channel 6001; In addition, the diameter of the connection between the spiral guide channel 6001 and the second connecting tube 5001 is larger than the diameter of the output end at the bottom of the spiral guide channel 6001, so that the spiral guide channel 6001 presents a unique shape of being wide at the top and narrow at the bottom. After the chemical enters the lower spiral from the upper spiral of the spiral guide channel 6001, its rotation radius decreases accordingly, causing the chemical to gradually increase its speed in the inner cavity of the spiral guide channel 6001. The high-speed chemical produces a strong impact on the inner wall of the spiral guide channel 6001. During the impact process, the components inside the chemical are further dispersed and mixed, forming a more efficient mixing effect, which provides strong support for improving the reaction efficiency and product uniformity of chemical synthesis. In addition, the second auxiliary reaction unit 6 further includes a plurality of flow guide components 6002, which are arranged at intervals along the inner wall of the spiral flow guide channel 6001, and the flow guide components 6002 are S-shaped, and every two flow guide components 6002 form a group and are symmetrically arranged on the inner wall of the spiral flow guide channel 6001. On the basis of adopting the spiral flow guide channel 6001 with a wide upper part and a narrow lower part, a plurality of S-shaped flow guide components 6002 are arranged on the inner wall of the spiral flow guide channel 6001, and these flow guide components 6002 are symmetrically distributed on the inner wall of the spiral flow guide channel 6001. When the chemical fluid flows through the spiral flow guide channel 6001, the S The shaped flow guide member 6002 can induce turbulence. At the same time, under the unique guiding effect of the flow guide member 6002, the chemical fluid is forced to move along the arc-shaped side wall of the flow guide member 6002. This moving mode causes the chemical fluids at the two corresponding groups of flow guide members 6002 to collide with each other, thereby further enhancing the mixing effect of the chemicals and improving the uniformity and efficiency of the chemical reaction. In addition, since the inner cavity of the spiral guide channel 6001 is set to a gradient shape that is wider at the top and narrower at the bottom, the speed of the chemicals moving along the spiral guide channel 6001 gradually increases. Therefore, the chemicals at different positions in the spiral guide channel 6001 will collide with the guide components 6002 at different positions, and the collision speeds are different. This collision phenomenon with speed differences makes the chemicals produce diverse mixing effects during the collision process, and the irregular speed changes provide a more complex and changeable fluid mechanics environment for the mixing of chemicals.

[0032] The working principle of a multifunctional chemical synthesis reactor in this embodiment is as follows: Before use, first adjust one of the first ball 4017 or the second ball 4020 to a state of connection with the cylinder 4008 according to the viscosity and density of the chemical to be synthesized: drive the second drive pin 4022 to move along the inner cavity of the second slide groove 4026 by opening the cylinder 4028, so that the second mounting seat 4021 drives the second moving frame 4018 to move along the outer wall of the limiting column 4012; at the same time, since the drive plate 4024 is rotatably connected to the rotating shaft 4023, the moving second drive pin 4022 drives the drive plate 4024 to rotate with the rotating shaft 4023 when moving. The first drive pin 4015 is driven to move along the first slide groove 4025, so as to prompt the first mounting seat 4014 to drive the first mobile frame 4013 to move along the outer wall of the limiting column 4012, that is, the first mobile frame 4013 and the second mobile frame 4018 are synchronously moved along the outer wall of the limiting column 4012, and the moving first mounting seat 4014 prompts the first ball 4017 connected to the end of the first connecting rod 4016 to insert into or detach from the inner cavity of the first slideway 4009, and the moving second mobile frame 4018 prompts the second ball 4020 connected to the end of the second connecting rod 4019 to move. 4010; specifically, when the first movable frame 4013 and the second movable frame 4018 move toward each other, the first ball 4017 is separated from the inner cavity of the first slide 4009, and the second ball 4020 is inserted into the inner cavity of the second slide 4010, that is, the second ball 4020 is connected with the cylinder 4008, thereby realizing that the later vertical movement interval of the pressure regulating plate 4004 is the interval of the vertical distance opened by the second slide 4010; when the first movable frame 4013 and the second movable frame 4018 move away from each other, the first ball 4017 is separated from the inner cavity of the first slide 4009, and the second ball 4020 is inserted into the inner cavity of the second slide 4010, that is, the second ball 4020 is connected with the cylinder 4008, thereby realizing that the vertical movement interval of the pressure regulating plate 4004 in the later stage is the interval of the vertical distance opened by the second slide 4010; When inserted into the inner cavity of the first slide 4009, the second ball 4020 is forced to detach from the inner cavity of the second slide 4010, that is, the connection between the first ball 4017 and the cylinder 4008 is realized, thereby realizing that the later vertical movement interval of the pressure regulating plate 4004 is the interval of the vertical distance opened by the first slide 4009; that is, when the first ball 4017 or the second ball 4020 selectively forms a connection relationship with the cylinder 4008, the lifting and lowering range of the pressure regulating plate 4004 can be flexibly adjusted, so as to flexibly adjust the pressure change interval of the vacuum environment according to the synthesis requirements of chemicals of different properties; After adjustment, the chemical to be reacted is put into the inner cavity of the reaction chamber 4001 through the feed port 7, and the stirring shaft 4003 and the stirring paddle 4031 are driven by the turned-on motor 3 to rotate circumferentially, so as to mechanically mix the chemicals in the inner cavity of the reaction chamber 4001 with the help of the rotation of the stirring paddle 4031; at the same time, the rotating stirring shaft 4003 drives the rotation of the cylinder 4008 to promote the synchronous rotation of the first slide 4009 and the second slide 4010, so as to promote the first ball 4017 or the second ball 4020 connected to the cylinder 4008 to move along the corresponding channel. Since there is a height difference between the opening of the first slide 4009 and the second slide 4010 on the cylinder 4008, the circumferential The rotating cylinder 4008 can cause the first ball 4017 or the second ball 4020 connected thereto to reciprocate in the vertical direction. Under the limiting and guiding action of the slider 4006 and the guide groove 4007, the pressure regulating plate 4004 can reciprocate in the vertical direction in the reaction chamber 4001. Since the reaction chamber 4001 and the area below the pressure regulating plate 4004 are both vacuum spaces, the pressure regulating plate 4004 that moves up and down and reciprocates can achieve regular vacuum pressure changes in the reaction area of ​​the reactants below the pressure regulating plate 4004. With the mechanical rotation and mixing of the stirring paddle 4031, the dual synergistic effect of mechanical mixing of materials and mixing with vacuum pressure changes can be achieved, thereby accelerating the reaction rate of chemical synthesis. After the chemical reacts in the inner cavity of the reaction chamber 4001, the opened electromagnetic valve 4033 forms a discharge channel, and the chemical enters the inner cavity of the second connecting cylinder 5001 downward through the first connecting cylinder 4032. Since the inner cavity of the second connecting cylinder 5001 is provided with multiple groups of flow blocking columns 5002 along the circumferential direction, the chemical is forced to change the direction of travel in the inner cavity of the second connecting cylinder 5001. The corresponding flow blocking columns 5002 of the upper and lower groups are staggered. When the chemical flows downward from the upper flow blocking column 5002 to the lower flow blocking column 5002, the chemical is further forced to change its direction of travel, thereby impacting and diverting the chemical falling from the top. The effect is to promote the dispersed entry of chemicals into the subsequent process, realize multi-angle impact and dispersion of chemicals, and realize the diversification and irregularity of the new entry path of chemicals through the vertical recessed portion 5003, the first inclined recessed portion 5004, and the second inclined recessed portion 5005, providing a multi-angle flow path for chemicals in the falling process. In the process of continuously changing the flow direction, the chemicals realize multi-angle impact and mixing in the inner cavity of the second connecting cylinder 5001. Each change in direction increases the probability of collision between the chemicals and the surfaces of different components, as well as the mutual contact opportunities between different components, thereby further improving the uniformity of chemical synthesis; The chemicals to be further mixed at the first auxiliary reaction unit 5 enter the inner cavity of the spiral guide channel 6001. Due to the unique spiral setting of the spiral guide channel 6001, the chemicals are prompted to form a spiral flow structure in the spiral guide channel 6001, forming a multi-level and multi-scale vortex structure, prompting the chemicals to form a strong turbulent effect in the spiral guide channel 6001, ensuring that the chemical fluid generates complex shear forces and pressure gradients during the rotation process, so as to achieve further mixing of the chemicals in the spiral guide channel 6001. The spiral guide channel 6001 presents a unique shape of being wide at the top and narrow at the bottom. After the chemicals enter the lower spiral from the upper spiral of the spiral guide channel 6001, their rotation radius decreases accordingly, prompting the speed of the chemicals in the inner cavity of the spiral guide channel 6001 to gradually increase. The high-speed chemicals have a strong impact on the inner wall of the spiral guide channel 6001. During the impact, the internal components of the chemicals are further dispersed and mixed. In addition, the inner wall of the spiral guide channel 6001 is provided with a number of S-shaped The spiral flow guide channel 6001 has an S-shaped flow guide member 6002, and these flow guide members 6002 are symmetrically distributed on the inner side wall of the spiral flow guide channel 6001. When the chemical fluid flows through the spiral flow guide channel 6001, the S-shaped flow guide member 6002 can cause turbulence. At the same time, under the unique guiding effect of the flow guide member 6002, the chemical fluid is forced to move along the arc-shaped side wall of the flow guide member 6002. This moving mode causes the chemical fluids at the two groups of flow guide members 6002 corresponding to each other to collide with each other, thereby further enhancing the mixing effect of the chemicals. Since the inner cavity of the spiral flow guide channel 6001 is set to a gradually changing shape with a width at the top and a narrowness at the bottom, the speed of the chemicals moving along the spiral flow guide channel 6001 gradually increases. Therefore, the chemicals at different positions in the spiral flow guide channel 6001 will collide with the flow guide members 6002 at different positions respectively, and the collision speeds are different. This collision phenomenon with speed differences causes the chemicals to produce diversified mixing effects during the collision process.
