Description

Technical Field

[0001] The invention belongs to the technical field of chemical synthesis equipment, and in particular relates to a multifunctional chemical synthesis reactor. Background Art

[0002] Chemical synthesis reactors are sealed containers, often made of stainless steel, which can allow materials to undergo various chemical reactions under certain pressures and temperatures, such as reactions in organic, inorganic, polymer chemistry, and biomedicine. They are easy to operate, can precisely control temperature, efficiently stir, and are highly safe, making them widely used in scientific research and industrial production.

[0003] Related Art 1 (Announcement No. CN215312324U) discloses a fine chemical synthesis reactor for uniform mixing. The reactor comprises a reactor body, a top plate movably mounted on the top of the reactor body, a motor movably mounted on the top of the top plate, a first rotating shaft fixedly connected to the output shaft of the motor, the first rotating shaft extending into the reactor body at one end remote from the motor and fixedly mounted with a plurality of stirring blades, a first bevel gear fixedly mounted on the outer side of the first rotating shaft, and two second rotating shafts rotatably mounted on the bottom of the top plate, each of the two second rotating shafts being fixedly connected to a second bevel gear at one end thereof. This utility model has a reasonable structural design and is simple to operate. It can evenly mix the chemicals by reciprocating up and down agitation, effectively improving the stirring effect of the chemicals.

[0004] Related Art 2 (Announcement No. CN211246574U) discloses a fine chemical synthesis reactor with uniform mixing, comprising a reactor body, a motor, and a compressed air pipe. A feed hopper is fixed to the top of the reactor body, and a material distribution trough is provided in the feed hopper. The motor is bolted to the outside of the feed hopper. An air outlet is connected to the top edge of the reactor body. The motor is bolted to the outside of the reactor body. A mixing disk is connected to the inner shaft of the reactor body, and the mixing disk is located below the stirring rod. One end of the mixing disk is connected to the output end of the motor. A movable groove is provided on the top of the mixing disk. A gear disk is welded to the top of the movable ring, and a guide hole is reserved in the gear disk. A shield is welded to the top edge of the mixing disk, and the shield is located above the gear. 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 technologies and existing chemical synthesis reactors, mixing of chemicals within the reactor cavity is usually achieved by rotating agitating blades. However, this traditional mixing method has the following significant drawbacks:

[0006] 1. Restrictions on material flow: Traditional mixing methods rely on mechanical force to drive fluid movement, which cannot effectively overcome the flow resistance caused by differences in viscosity and density of materials. The material flow pattern is single and cannot break through static flow restrictions, resulting in low mixing efficiency, affecting reaction rate and product quality.

[0007] 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 throughout the reactor cavity. This is especially true for high-viscosity or non-Newtonian fluids, where the mixing efficiency is significantly reduced.

[0008] 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.

[0009] In summary, existing chemical synthesis reactors rely solely on stirring blades to achieve mixing, which has problems such as material flow restriction, limited mixing efficiency, and the existence of stirring blind spots. As a result, the efficiency of compound synthesis in the reactor is low and the energy consumption of the synthesis process is high. Summary of the Invention

The first inclined recessed portion, the vertical recessed portion, and the second inclined recessed portion form a recessed guide groove with inclined ends and a vertical middle portion.

[0030] Wherein, the second connecting tube is connected to the first connecting tube;

[0031] In addition, the flow-blocking columns are stacked in multiple groups, and the upper and lower groups of flow-blocking columns are staggered.

[0032] In the above technical solution, the bottom end of the second connecting tube is connected to the second auxiliary reaction unit;

[0036] In addition, a feed port is provided on the side wall of the reactor body, the end of the feed port extends into the reaction chamber, and the position of the feed port is always lower than the position of the pressure regulating plate. 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.

[0037] Compared with the prior art, the multifunctional chemical synthesis reactor of the present invention has the following beneficial effects:

[0038] First, in response to the problem that the existing chemical synthesis reactor uses traditional stirring methods and mainly relies 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. 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, which enables dynamic mixing of chemicals under different pressure environments. Specifically, the present invention uses this regular contraction mechanism to greatly enhance the mixing efficiency of the fluid through periodic vacuum pressure changes, successfully breaking through the inherent limitations of traditional static vacuum systems on 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 deeply penetrate into the interior of materials with viscosity or density differences, effectively prompting the materials to break through the constraints of static flow;

[0039] Second, in response to the problem that existing stirring blades can only generate shear force and turbulence in local areas, making it difficult to achieve uniform mixing of the entire reactor cavity, especially in high-viscosity or non-Newtonian fluids, the mixing efficiency is significantly reduced. The present invention, based on the provision of a stirring paddle, combines regular vacuum pressure changes to achieve a dual synergistic effect of mechanical mixing of materials and mixing by vacuum pressure changes. Specifically, the present invention combines this vacuum pressure change mixing method with a rotating stirring paddle component to achieve a dual synergistic effect of mechanical mixing of materials and mixing by 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 quality of the products after chemical synthesis, thereby realizing the multifunctional application of chemical synthesis;

[0040] 3. In view of the problem that the existing stirring blades cannot completely cover the inner wall and bottom area of ​​the reactor during rotation, resulting in the accumulation of materials in dead corners, forming mixing blind spots, affecting the reaction uniformity and product quality, and requiring 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, the present invention can indiscriminately and comprehensively mix the reaction area below the pressure regulating plate, 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 are 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;

[0041] 4. In traditional methods, if you want to achieve two different mixing mechanisms, mechanical stirring and vacuum pressure change mixing, you usually need to configure multiple independent power systems, which invisibly increases 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 achieve mechanical stirring and mixing is the same power source used to drive the pressure regulating plate of the component to move up and down to achieve vacuum pressure change mixing. That is, the present invention achieves dual effects through a single power source, reducing the complexity of the power system and the overall cost of the equipment, reducing energy consumption, and improving energy utilization efficiency. 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 allows the material to be subjected to both the stirring action of the mechanical force and the flow and mixing effect brought about by the pressure change at the same time, avoiding the problem of inconsistent mixing timing caused by differences in the start-up and operation time of different power sources, thereby achieving more efficient and uniform material mixing, which helps 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 components 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.

[0042] 5. In the present invention, a cylinder and a first slide are provided on the stirring shaft, which cooperate with the first ball to realize the lifting and reciprocating movement of the pressure regulating plate, converting the circumferential rotation 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 use 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, promoting the chemicals in the reactor to react fully and effectively from different levels and angles, and providing a strong guarantee for improving the chemical reaction rate and product quality stability.

[0043] 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. Through the cooperation of the first slide and the first ball, the pressure regulating plate can be lifted and reciprocated in a relatively small range, so as to promote the vacuum environment pressure below the pressure regulating plate to change in a small range. Through the cooperation of the second slide and the second ball, the pressure regulating plate can be lifted and reciprocated in a relatively large range, so as to promote the vacuum environment pressure below the pressure regulating plate to change in a large range. 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 adaptive reaction conditions for chemical synthesis in a multifunctional and diversified manner, thereby effectively improving the efficiency of the synthesis reaction and the quality of the product.

[0044] 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 drive plate, one of the first ball and the second ball can be put into the working state and the other can be switched to the inactive state, ensuring that the two can achieve normal and stable switching between the active state and the inactive state, meeting the use requirements under different working conditions and improving the flexibility and adaptability of the equipment operation;

[0045] 8. The present invention can achieve the relative adjustment of the positions of the first and second balls at one time through the linkage of the cylinder, the rotating shaft, the drive plate, the first chute, and the second chute. That is, the present invention does not require the complicated operation of driving the first and second balls to move in separate steps, which greatly simplifies the adjustment process, improves the adjustment efficiency, and enhances the consistency and stability of the equipment operation.

[0046] 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. This means that during the process of adjusting the positions of the first and second balls, there is a transition state, that is, while the first ball is still embedded in the first slide cavity, the second ball has also entered the second slide cavity. This ensures that when the first and second balls 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 the cylinder, and ensuring the safety and stability of the equipment operation.

[0047] 10. In the present invention, a top plate is provided above the inner cavity of the reaction chamber. When the pressure regulating plate reciprocates vertically in the inner cavity of the reaction chamber to adjust the vacuum pressure, the space between the top plate and the reaction chamber can still be maintained in a vacuum state, providing a reliable guarantee for the reaction of chemicals in a vacuum environment, avoiding interference with the chemical reaction by external factors, and facilitating improvement of the efficiency of the chemical reaction and the purity of the product.

[0048] 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 lowering movement of the pressure regulating plate, moving synchronously in the corresponding direction. The provision 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 sides of the pressure regulating plate can be maintained in a vacuum state. When the pressure regulating plate is raised and lowered, the pressure in the chemical reaction area below it can be accurately and effectively adjusted, providing solid and reliable technical support for the reaction of chemicals in a specific vacuum pressure environment, effectively ensuring the efficient conduct of chemical reactions and the stability of product quality.

[0049] 12. The present invention realizes flexible and precise control of the communication state between the reaction chamber and the second connecting tube by providing a first connecting tube and a solenoid valve. In actual operation, when the first connecting tube is in a closed state, it can effectively block the communication between the reaction chamber and the second connecting tube of the external environment, ensuring that a closed vacuum environment is maintained inside the reaction chamber. Under this environment, the two functions of mechanical mixing and vacuum pressure change mixing possessed by the present invention can operate stably, providing good conditions for the full mixing and reaction of chemicals. When the first connecting tube is in an open state, the reaction chamber and the second connecting tube are connected, and the fully mixed chemicals can flow smoothly downward to enter the subsequent process steps, thereby effectively integrating the reaction and subsequent treatment 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.

[0050] 13. The present invention provides multiple groups of flow-blocking columns equidistantly arranged around the inner cavity of the second connecting cylinder. These columns can impact and guide the chemicals falling from the top, promoting their dispersed entry into subsequent processes. This achieves multi-angle impact and dispersion of the chemicals, providing further mixing for chemical synthesis. Specifically, the present invention, through the provision of multiple groups of flow-blocking columns, allows for more complete contact between the various components of the chemicals, creating more favorable conditions for the chemical synthesis reaction, helping to improve the efficiency of the chemical reaction and the quality of the product, effectively enhancing the performance of the entire synthesis process.

[0051] 14. In the present invention, each set of flow-blocking columns is provided with a vertical recess, a first inclined recess, and a second inclined recess. These components provide multi-angle flow paths for the chemicals during their fall. As the chemicals continuously change their flow direction, they collide and mix at multiple angles within 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 chance of contact between different components. This further improves the uniformity of chemical synthesis, effectively optimizes the reaction conditions for chemical synthesis, and contributes to improved product quality and reaction efficiency.

[0052] 15. In the present invention, the upper and lower groups of corresponding obstruction columns are staggered. When chemicals flow downward from the upper obstruction column to the lower obstruction column, this staggered layout can further force the chemicals to change their direction of travel due to its unique spatial structure. This change in direction of the chemicals allows them to contact more reaction spaces and components in different locations during the flow process, thereby increasing the chances of mixing and collision between the various chemical components, effectively promoting the uniformity of chemical synthesis, and providing an important guarantee for improving the efficiency of chemical reactions and product quality.

[0053] 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 forces and pressure gradients during the rotation process, thereby achieving further mixing of chemicals in the spiral guide channel;

[0054] 17. In the design architecture of the present invention, the diameter of the connection between the spiral guide channel and the second connecting tube is larger than the diameter of the output end at the bottom of the spiral guide channel, giving the spiral guide channel a unique shape: wide at the top and narrow at the bottom. As the chemical enters the lower spiral from the upper spiral of the spiral guide channel, its rotation radius decreases, causing the chemical to gradually increase its speed in the spiral guide channel cavity. The high-speed chemical produces a strong impact on the inner wall of the spiral guide channel. During this impact, the various components within the chemical are further dispersed and mixed, forming a more efficient mixing effect, providing strong support for improving the reaction efficiency and product uniformity of chemical synthesis.

[0055] 18. In the present invention, while adopting a spiral flow guide channel that is wide at the top and narrow at the bottom, several S-shaped flow guide members are provided on the inner sidewalls of the spiral flow guide channel. These flow guide members are symmetrically distributed along the inner sidewalls of the spiral flow guide channel. When the chemical fluid flows through the spiral flow guide channel, the S-shaped flow guide members can induce turbulence. At the same time, under the unique guiding effect of the flow guide members, the chemical fluid is forced to travel along the curved sidewalls of the flow guide members. This travel mode causes the chemical fluids at the two corresponding groups of flow guide members to collide with each other, thereby further enhancing the mixing effect of the chemicals and improving the uniformity and efficiency of the chemical reaction.

[0056] 19. Because the inner cavity of the spiral flow channel is configured in a gradually changing shape, wide at the top and narrow at the bottom, the speed of the chemicals traveling along the spiral flow channel gradually increases. Therefore, the chemicals at different locations within the spiral flow channel will collide with the flow guide components at different locations, and the collision speeds vary. This collision phenomenon with different speeds produces diverse mixing effects for the chemicals during the collision process. The irregular speed changes provide a more complex and variable fluid dynamic environment for chemical mixing. Compared with traditional regular flow, this irregular speed movement can promote more complete contact, friction, and mixing between chemicals, thereby further improving the mixing uniformity of the chemicals and creating favorable conditions for efficient chemical reactions and improved product quality.

[0057] 20. The present invention integrates multiple functions such as mechanical mixing, vacuum pressure change mixing, flow resistance collision mixing, spiral mixing, and diversion mixing to achieve multiple mixing effects on chemicals. The above-mentioned multifunctional mixing method can achieve sufficient, uniform, and high-quality mixing effects of chemicals from multiple dimensions and levels;

[0058] 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 with mechanical stirring to achieve double synergistic mixing, significantly improves mixing efficiency and uniformity, accelerates the reaction process and ensures product quality; in the design of the power system, a single power source is used to drive two mixing mechanisms, which reduces cost and energy consumption, ensures the synchronization of the two action timings, reduces maintenance workload, and improves equipment reliability and service life; the design and layout of components are sophisticated, realizing lifting and moving conversion, and flexible The pressure change range is adjusted to adapt to different synthesis needs, key components are ensured to be firmly connected, and a vacuum environment is maintained. Special components impact, divert, break up and mix chemicals, and the unique structure is used to force 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, production consistency and efficiency are improved, providing a more efficient and stable solution for chemical synthesis. The use of multifunctional mixing methods such as mechanical mixing, vacuum pressure change mixing, flow control collision mixing, spiral mixing, and diversion mixing can achieve sufficient, uniform, and high-quality mixing of chemicals from multiple dimensions and levels.

When the motor 3 is turned on, the stirring shaft 4003 and the stirring paddle 4031 can be driven to rotate circumferentially to achieve mechanical mixing of the chemicals in the cavity of the reaction chamber 4001; in addition, a feed port 7 is provided on the side wall of the reactor body 1, and the feed port 7 can be connected to the existing pumping material system on the market to assist the chemicals to be more effectively fed through the feed port 7 Entering into the reaction bin 4001, the end of the feed port 7 extends into the reaction bin 4001, and the position of the feed port 7 is always lower than the position of the pressure regulating plate 4004. The chemicals to be reacted can be put into the inner cavity of the reaction bin 4001 through the feed port 7, and the lifting and lowering movement of the pressure regulating plate 4004 will not interfere with the feeding of the feed port 7. 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.

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 the material to the outside.

[0078] 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 mixing not only significantly accelerates the reaction rate of chemical synthesis, but also can more finely and comprehensively guarantee the quality of the products after chemical synthesis, and realize the multifunctional application of chemical synthesis; in addition, the present invention can perform comprehensive mixing on the reaction area below the pressure regulating plate 4004 indiscriminately and comprehensively, and drive the materials to fully flow and mix in the reaction area through periodic vacuum pressure changes, successfully solving the problem of dead corner 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, reducing energy consumption problems caused by long-term stirring, and providing a more efficient production model for chemical synthesis.

[0079] 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 regularly changes the vacuum pressure of the reaction environment in the inner cavity of the reaction chamber 4001, thereby assisting the stirring paddle 4031 in accelerating the dynamic mixing of chemicals.

When the pressure regulating plate 4004 is raised and lowered, the vacuum pressure in the reaction space below it can be accurately adjusted. By controlling the movement amplitude of the pressure regulating plate 4004, the vacuum pressure of the reaction space can be accurately controlled, thereby providing a stable and suitable pressure environment for the chemical reaction, and improving the reaction efficiency and product quality in a targeted manner.

[0084] 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 to the cylinder 4008, thereby realizing that the vertical movement range of the pressure regulating plate 4004 in the later stage is the vertical distance range 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 inserted into the inner cavity of the first slide 4009, and the second ball 4020 is connected to the cylinder 4008. 009 cavity, at the same time, the second ball 4020 is prompted to disengage from the second slide 4010 cavity, that is, the connection between the first ball 4017 and the cylinder 4008 is realized, thereby realizing the later vertical movement range of the pressure regulating plate 4004, which 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 amplitude of the pressure regulating plate 4004 can be flexibly adjusted to flexibly adjust the pressure change range of the vacuum environment according to the synthesis requirements of chemicals of different properties.

[0085] Main references Figure 10 and Figure 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 via a bearing. The driving plate 4024 has a first slide groove 4025 and a second slide groove 4026 at both ends. The adjustment mechanism also includes a support frame 4027 fixedly mounted on the upper surface of the pressure adjustment plate 4004. A cylinder 4028 is mounted on the support frame 4027. The output end of the cylinder 4028 is fixedly connected to the second driving pin 4022. 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.

[0086] The second driving pin 4022 is driven by the opened cylinder 4028 to move along the inner cavity of the second slide groove 4026, so that the second mounting seat 4021 drives the second movable 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 to the rotating shaft 4023, when the 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 movable frame 4013 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, 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 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.

[0087] The specific process of the mixing reaction of chemicals in the collaborative 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 to it to move back and forth 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 move back and forth in the vertical direction in the reaction chamber 4001. Since the reaction chamber 4001 and the area below the pressure regulating plate 4004 are vacuum spaces, the pressure regulating plate 4004 that moves up and down and back and forth can achieve regular vacuum pressure changes in the reaction area of ​​the reactant 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.

[0088] Main references Figure 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 passes through the sealing sleeve 4030 in the vertical direction and is rotatably connected to 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 performance. During the compression process of the corrugated airbag 4029, this sealing performance will not be affected, thereby preventing external gas from entering or internal gas from leaking.

[0089] 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. The chemicals after the reaction in the inner cavity of the reaction chamber 4001 form a discharge channel through the opened solenoid valve 4033 to enable the chemicals to flow to the next process.

[0090] Main references Figures 4 to 6 、 Figures 12 to 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 circumferentially in the second connecting tube 5001. Each flow-blocking column 5002 is provided with a vertical recessed portion 5003, a first inclined recessed portion 5004, and a second inclined recessed portion 5005 on the side away from the inner side wall of the second connecting tube 5001. 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 chemical entry path, providing a multi-angle flow path for the chemicals during the falling process. As the chemicals continue to change their flow direction, they achieve 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 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. In addition, mainly refer to Figure 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 their direction of travel in the inner cavity of the second connecting tube 5001. The staggered arrangement of the obstruction columns 5002 corresponding to the upper and lower groups is adopted. 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, and realizing multi-angle impact and dispersion of the chemicals.

[0091] Main references Figure 15 and Figure 16 As shown, the bottom end of the second connecting cylinder 5001 is connected to the second auxiliary reaction unit 6; the second auxiliary reaction unit 6 includes a spiral guide channel 6001 connected to the bottom end of the second connecting cylinder 5001. The spiral guide channel 6001 is configured to be spiral, which can promote the formation of a spiral flow structure of chemicals in the spiral guide channel 6001, forming a multi-level and multi-scale vortex structure, and promoting the formation of a strong turbulent effect of chemicals 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 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 at the bottom end of the spiral guide channel 6001;

[0092] 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, giving the spiral guide channel 6001 a unique shape that is 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, 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 various components within the chemical are further dispersed and mixed, forming a more efficient mixing effect, providing strong support for improving the reaction efficiency and product uniformity of chemical synthesis.

[0093] In addition, the second auxiliary reaction unit 6 further includes a plurality of flow guide members 6002, which are arranged at intervals along the inner wall of the spiral flow guide channel 6001. The flow guide members 6002 are S-shaped, and each two flow guide members 6002 form a group and are symmetrically arranged on the inner wall of the spiral flow guide channel 6001. On the basis of adopting a spiral flow guide channel 6001 with a wide upper part and a narrow lower part, a plurality of S-shaped flow guide members 6002 are arranged on the inner wall of the spiral flow guide channel 6001, and these flow guide members 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, S The curved flow guide members 6002 can induce turbulence. Simultaneously, under the unique guiding effect of the flow guide members 6002, the chemical fluid is forced to travel along the curved sidewalls of the flow guide members 6002. This travel mode causes the chemical fluids at the two corresponding sets 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.

[0094] 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 causes the chemicals to 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.

[0097] 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: 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 to the rotating shaft 4023, the moving second driving pin 4022 drives the driving plate 4024 to rotate with the rotating shaft 4023 when it moves. The shaft rotates to drive the first driving pin 4015 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 move synchronously 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 out of 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 be inserted into or out of the inner cavity of the first slideway 4009. 4010, and the second slide 4010 is opened. 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 vertical movement range of the pressure regulating plate 4004 in the later stage is the vertical distance range 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 range of the pressure regulating plate 4004 in the later stage is the vertical distance range opened by the second slide 4010; When the second ball 4020 is inserted into the inner cavity of the first slide 4009, it is forced to disengage from the inner cavity of the second slide 4010, that is, the first ball 4017 is connected to the cylinder 4008, thereby achieving the vertical movement range of the pressure regulating plate 4004 in the later stage, which is the vertical distance range 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 range 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;

[0098] After adjustment, the chemicals to be reacted are fed 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 to rotate circumferentially by the turned-on motor 3, 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 be reciprocated in the vertical direction within the reaction chamber 4001. Since the reaction chamber 4001 and the area below the pressure regulating plate 4004 are both vacuum spaces, the reciprocating movement of the pressure regulating plate 4004 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 the materials and vacuum pressure changes is achieved, thereby accelerating the reaction rate of chemical synthesis.

[0099] After the chemical reacts in the inner cavity of the reaction chamber 4001, the opened solenoid valve 4033 forms a discharge channel, and the chemical flows downward into the inner cavity of the second connecting cylinder 5001 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 its 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 vertical recess 5003, the first inclined recess 5004, and the second inclined recess 5005 diversify and irregularize the new entry paths of the chemicals, providing multi-angle flow paths for the chemicals during their fall. As the chemicals continuously change their flow direction, they collide and mix at multiple angles 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 chance of contact between different components, thereby further improving the uniformity of chemical synthesis.

[0100] The chemicals that are 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 has a unique shape that is 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 chemicals to gradually accelerate in the inner cavity of the spiral guide channel 6001. The high-speed chemicals produce a strong impact on the inner wall of the spiral guide channel 6001. During the impact, the various components inside the chemicals are further dispersed and mixed. In addition, the inner wall of the spiral guide channel 6001 is provided with several S-shaped The S-shaped flow guide members 6002 are symmetrically distributed along the inner sidewalls of the spiral flow guide channel 6001. When the chemical fluid flows through the spiral flow guide channel 6001, the S-shaped flow guide members 6002 can induce turbulence. At the same time, under the unique guiding effect of the flow guide members 6002, the chemical fluid is forced to travel along the curved sidewalls of the flow guide members 6002. This flow pattern causes the chemical fluids at the two corresponding sets of flow guide members 6002 to collide with each other, further enhancing the chemical mixing effect. Because the inner cavity of the spiral flow guide channel 6001 is configured with a gradually changing shape from wider at the top to narrower at the bottom, the speed of the chemical traveling along the spiral flow guide channel 6001 gradually increases. Therefore, the chemical at different positions within the spiral flow guide channel 6001 will collide with the flow guide members 6002 at different positions, and the collision speeds vary. This collision phenomenon with different speeds produces diverse mixing effects for the chemicals during the collision process.

[0101] Aiming at the limitations of traditional chemical synthesis reactors, the present invention 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 with mechanical stirring to achieve dual 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, reducing costs and energy consumption, ensuring synchronization of the two action timings, reducing maintenance workload, and improving equipment reliability and service life; the component design and layout are sophisticated, realizing lifting and moving conversion, and flexible adjustment The pressure change range is adjusted to adapt to different synthesis needs, ensuring the stable connection of key components and maintaining the vacuum environment. Special components impact, guide, break up and mix chemicals, and use the unique structure to force chemicals to form complex flow structures and turbulence, further enhancing the mixing effect; by precisely controlling the connectivity state, effectively integrating the reaction and subsequent processing procedures, improving production consistency and efficiency, and providing a more efficient and stable solution for chemical synthesis; using mechanical mixing, vacuum pressure change mixing, flow control collision mixing, spiral mixing, diversion mixing and other multifunctional mixing methods as one, it can achieve full, uniform and high-quality mixing effects of chemicals from multiple dimensions and levels.
