Description

Technical Field

[0001] This invention relates to the field of emulsion synthesis technology, and more particularly to an emulsion synthesis reaction apparatus with a cooling mechanism. Background Technology

[0002] Emulsion polymerization is a polymerization method that uses water as the dispersion medium and emulsifiers to stably disperse olefin monomers into an emulsion state. It is an important process for producing various synthetic resins, synthetic rubbers, coatings, adhesives, and other products. Emulsion synthesis reactions are typically carried out in a reactor equipped with a stirrer. Precise temperature control is crucial to ensure stable polymerization and consistent product quality. Existing emulsion synthesis reactors generally include a reactor body, a stirring mechanism, a temperature control system (such as jackets and coils), and various auxiliary components. Since emulsion polymerization is an exothermic reaction, timely removal of the heat of reaction is critical to ensuring reaction safety and product quality.

[0003] However, whether it is the vessel wall jacket or the spiral coil, the cooling medium adopts a single series path flow mode. The cooling water temperature is low in the inlet section and the heat exchange driving force is large. When the cooling water flows through the middle and rear sections, the temperature will rise significantly due to continuous heat absorption, resulting in serious temperature unevenness between the upper and lower parts of the vessel. This will lead to different reaction rates in different areas of the vessel, so improvements are urgently needed. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an emulsion synthesis reaction device with a cooling mechanism, which aims to solve the technical problem that the cooling medium uses a single series flow path, resulting in heat absorption and temperature rise along the process, large temperature difference between the top and bottom of the reactor, and uneven reaction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An emulsion synthesis reaction apparatus with a cooling mechanism includes a support frame, a vessel body, and a vessel lid, and further includes: The cooling chamber is located inside the side wall of the vessel body; The right-side distributor is fixedly mounted on the outer wall of the vessel. The first annular cooling hood is provided in multiple ways. Multiple first annular cooling hoods are arranged in the cooling chamber. The first annular cooling hoods and the vessel body together form the first cooling chamber. There are multiple right-side infusion tubes. One end of each right-side infusion tube is connected to the inside of the right-side shunt, and the other end of each right-side infusion tube is connected to the first cooling chamber inside a first annular cooling hood. The left-side reflux valve is fixedly installed on the outer wall of the vessel. There are multiple left-side return pipes. One end of each left-side return pipe is connected to the inside of the left-side return device, and the other end of each left-side return pipe is connected to the first cooling chamber inside a first annular cooling hood. The left-side distributor is fixedly mounted on the outer wall of the vessel. Multiple second annular cooling hoods are provided, and multiple second annular cooling hoods are arranged in the cooling chamber. The second annular cooling hoods and the vessel body together form the second cooling chamber. There are multiple infusion tubes on the left side. One end of each of the multiple infusion tubes on the left side is connected to the inside of the left shunt, and the other end of each infusion tube on the left side is connected to the second cooling chamber inside a second annular cooling hood. The right-side reflux valve is fixedly installed on the outer wall of the vessel. There are multiple right-side return pipes. One end of each right-side return pipe is connected to the inside of the right-side return device, and the other end of each right-side return pipe is connected to the second cooling chamber inside a second annular cooling hood. A stirring mechanism, located on the lid of the vessel, is used to stir the raw materials; The reciprocating feeding mechanism is installed on the mixing mechanism.

[0006] Preferably, a plurality of first annular cooling covers are arranged at intervals along the vertical direction, a plurality of second annular cooling covers are arranged at intervals along the vertical direction, and the first annular cooling covers and the second annular cooling covers are alternately arranged in the vertical direction.

[0007] Preferably, the side wall of the vessel body is provided with a bottom water inlet and a top water outlet, and both the bottom water inlet and the top water outlet are connected to the cooling chamber.

[0008] Preferably, the right-side distributor has a right-side inlet, and the left-side return distributor has a left-side outlet.

[0009] Preferably, the left-side distributor has a left-side inlet, and the right-side return distributor has a right-side outlet.

[0010] Preferably, the stirring mechanism includes: The first motor is fixedly installed on the top of the kettle lid; The rotating roller is sealed and rotates on the lid of the vessel, with one end fixedly connected to the output end of the first motor. There are two agitators, which are symmetrically fixed on the rotating roller.

[0011] Preferably, the reciprocating feeding mechanism includes: Two guide rods are provided, with one end of each guide rod symmetrically fixed on the rotating roller; The push plate is slidably mounted on the guide rod. The lifting assembly is mounted on the rotating roller.

[0012] Preferably, the lifting assembly includes: The sealing lifting sleeve is slidably mounted on the rotating roller and is slidably connected to the kettle lid. The drive rod is fixedly mounted on the sealing lifting sleeve and slidably connected to the vessel lid; Two fixed frames are provided, and the two fixed frames are symmetrically fixedly installed on the sealing lifting sleeve; The conversion unit is mounted on a fixed frame.

[0013] Preferably, the conversion unit includes: The first fixing rod is fixedly installed on the fixing frame; The second fixing rod is located at the top of the push plate and its two ends are fixedly connected to the push plate.

[0014] Preferably, a drive guide groove is provided inside the lid, and one end of the drive rod extends into the drive guide groove. The drive guide groove is used to convert the rotational motion of the drive rod that rotates with the roller into axial reciprocating lifting motion.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. Through the coordination of the right-side distributor, the first annular cooling shroud, the first cooling chamber, the left-side reflux device, the left-side distributor, the second annular cooling shroud, the second cooling chamber, and the right-side reflux device, cooling water enters simultaneously from both sides and is distributed to each cooling chamber. Since the first annular cooling shroud and the second annular cooling shroud are alternately arranged in the vertical direction, the inlet and outlet of adjacent cooling chambers form a complementary temperature difference, eliminating the dead zone of temperature rise along the flow path of single-flow cooling and the problem of uneven temperature between the upper and lower parts of the vessel body, ensuring uniform cooling of the entire vessel wall, and avoiding different reaction rates in different areas due to differences in wall temperature.

[0016] 2. Through the cooperation between the stirring mechanism and the reciprocating pushing mechanism, the first motor drives the rotating roller to rotate, and the rotational motion is converted into the reciprocating lifting of the sealing lifting sleeve through the drive guide groove. The motion is then transmitted to the push plate through the fixed frame, the conversion plate and the second fixed rod, so that the push plate reciprocates along the guide rod while rotating. This forces the high-temperature material in the reactor core to the reactor wall and pushes the cooled material back to the center. This changes static heat conduction to forced convection heat transfer, opens up the heat transfer path blocked by the high-viscosity material, eliminates the temperature gradient between the cold wall and the hot reactor core, and avoids the overheating and degradation of the product in the reactor core.

[0031] Reference Figures 1 to 8 An embodiment of an emulsion synthesis reaction apparatus with a cooling mechanism according to the present invention will be further described.

[0032] An emulsion synthesis reaction apparatus with a cooling mechanism includes a support frame 1, a vessel body 2, and a vessel lid 3, and further includes: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 In a preferred embodiment, the cooling chamber 4 is formed inside the side wall of the vessel body 2. The side wall of the vessel body 2 is provided with a bottom water inlet 17 and a top water outlet 18. Both the bottom water inlet 17 and the top water outlet 18 are connected to the cooling chamber 4. It should be noted that the cooling chamber 4, the bottom water inlet 17 and the top water outlet 18 are used to introduce and discharge the cooling medium to provide auxiliary heat exchange for the first annular cooling shroud 6 and the second annular cooling shroud 12. The right-side distributor 5 is fixedly installed on the outer wall of the vessel body 2; the right-side distributor 5 is equipped with a right-side water inlet 19; it should be noted that the right-side water inlet 19 is used to receive externally supplied cooling water, and the right-side distributor 5 is used to evenly distribute the cooling water to each right-side delivery pipe 8. Multiple first annular cooling covers 6 are provided, and multiple first annular cooling covers 6 are arranged in the cooling chamber 4. The first annular cooling covers 6 and the vessel body 2 together form the first cooling chamber 7. There are multiple right-side infusion tubes 8. One end of each right-side infusion tube 8 is connected to the inside of the right-side shunt 5, and the other end of each right-side infusion tube 8 is connected to the first cooling chamber 7 inside a first annular cooling hood 6. The left reflux device 9 is fixedly installed on the outer wall of the vessel body 2, and the left reflux device 9 is provided with a left outlet 20; it should be noted that the left reflux device 9 is used to collect the cooling water after flowing through the first cooling chamber 7, and the left outlet 20 is used to discharge the cooling water from the external receiving box. Multiple left-side return pipes 10 are provided. One end of each left-side return pipe 10 is connected to the inside of the left-side return device 9, and the other end of each left-side return pipe 10 is connected to the first cooling cavity 7 inside a first annular cooling hood 6. The left-side distributor 11 is fixedly installed on the outer wall of the vessel body 2, and the left-side distributor 11 is provided with a left-side water inlet 21; Multiple second annular cooling covers 12 are provided, and multiple second annular cooling covers 12 are disposed in the cooling chamber 4. The second annular cooling covers 12 and the vessel body 2 together form a second cooling chamber 13. Multiple first annular cooling covers 6 are arranged at intervals in the vertical direction, and multiple second annular cooling covers 12 are arranged at intervals in the vertical direction, and the first annular cooling covers 6 and the second annular cooling covers 12 are alternately arranged in the vertical direction. There are multiple left-side infusion tubes 14. One end of each left-side infusion tube 14 is connected to the inside of the left-side shunt 11, and the other end of each left-side infusion tube 14 is connected to the second cooling chamber 13 inside a second annular cooling hood 12. The right-side reflux device 15 is fixedly installed on the outer wall of the vessel body 2, and the right-side reflux device 15 is provided with a right-side outlet 22; Multiple right-side return pipes 16 are provided. One end of each right-side return pipe 16 is connected to the inside of the right-side return device 15, and the other end of each right-side return pipe 16 is connected to the second cooling chamber 13 inside a second annular cooling hood 12. During operation, cooling water is simultaneously supplied from both the right inlet 19 and the left inlet 21 via an externally connected water supply assembly. The cooling water then enters the right distributor 5 and the left distributor 11 from the right inlet 19 and left inlet 21, respectively. The right distributor 5 evenly distributes the cooling water to multiple right-side delivery pipes 8, and then the cooling water simultaneously enters the first cooling chamber 7 of each of the first annular cooling hoods 6. After flowing through, it converges from the left return pipe 10 into the left return device 9 and is discharged through the left outlet 20. Similarly, the left distributor 11 evenly distributes the cooling water to multiple left-side delivery pipes 14, and then the cooling water simultaneously enters the second cooling chamber 13 of each of the second annular cooling hoods 12. After flowing through, it converges from the right return pipe 16 into the right return device 15. The water is discharged through the outlet 22 on the right side. Since the first annular cooling shroud 6 and the second annular cooling shroud 12 are alternately arranged in the vertical direction, the inlet and outlet of the adjacent cooling chambers complement each other in space. When the heat exchange capacity of the outlet side of any cooling chamber decreases due to the cooling water absorbing heat along the flow path, the corresponding side of the adjacent cooling chamber is exactly the low temperature water inlet end. This achieves mutual compensation of cooling intensity in the axial and circumferential directions, completely eliminating the inherent dead angle of temperature rise along the flow path of single-flow cooling and the serious uneven temperature between the upper and lower parts of the vessel body 2, ensuring that the entire vessel wall obtains a uniform cooling effect. Moreover, the bottom water inlet 17 at the bottom of the side wall of the vessel body 2 and the top water outlet 18 at the top form an additional overall convection around the jacket of the cooling chamber 4, further assisting in temperature uniformity.

[0033] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 In a preferred embodiment, a stirring mechanism is disposed on the vessel lid 3 for stirring the raw materials; the stirring mechanism includes: The first motor 23 is fixedly installed on the top of the kettle cover 3; The rotating roller 24 is sealed and rotatably mounted on the lid 3, and one end is fixedly connected to the output end of the first motor 23; There are two stirring paddles 25, which are symmetrically fixed on the rotating roller 24.

[0034] A drive guide groove 34 is provided inside the lid 3. One end of the drive rod 29 extends into the drive guide groove 34. It should be noted that the drive guide groove 34 has a contour with ups and downs, which is used to convert the rotational motion of the drive rod 29 that rotates with the roller 24 into axial reciprocating lifting motion.

[0035] A reciprocating feeding mechanism is mounted on the mixing mechanism. The reciprocating feeding mechanism includes: Two guide rods 26 are provided, and one end of each guide rod 26 is symmetrically fixed on the rotating roller 24. Push plate 27 is slidably mounted on guide rod 26; A lifting assembly, mounted on the rotating roller 24, includes: The sealing lifting sleeve 28 is slidably mounted on the rotating roller 24 and is slidably connected to the kettle cover 3. The drive rod 29 is fixedly mounted on the sealing lifting sleeve 28 and is slidably connected to the vessel lid 3; Two fixing brackets 30 are provided, and the two fixing brackets 30 are symmetrically fixed on the sealing lifting sleeve 28; The conversion unit is mounted on the mounting bracket 30 and includes: The first fixing rod 31 is fixedly mounted on the fixing frame 30; The second fixing rod 32 is located at the top of the push plate 27 and its two ends are fixedly connected to the push plate 27. The conversion plate 33 is rotatably mounted on the first fixed rod 31 and rotatably connected to the second fixed rod 32.

[0036] During operation, the first motor 23 is started, driving the rotating roller 24, which is fixedly connected to its output end, to rotate. The rotating roller 24 drives the stirring paddle 25 and the guide rod 26 to rotate synchronously. The guide rod 26 drives the drive rod 29 to rotate via the push plate 27, the second fixed rod 32, the conversion plate 33, the first fixed rod 31, the fixed frame 30, and the sealing lifting sleeve 28. Because the drive guide groove 34 has an undulating trajectory in the circumferential direction, the drive rod 29 is forced to rise or fall by the trajectory of the drive guide groove 34 during rotation. The drive rod 29 then drives the sealing lifting sleeve 28 to slide and rise on the rotating roller 24. The sealing lifting sleeve 28 drives the fixed frame 30 to move down synchronously. The lifting motion is transmitted to the second fixed rod 32 through the first fixed rod 31 and the conversion plate 33. Since the height of the second fixed rod 32 is locked, the push plate 27 is driven to make regular reciprocating motion on the guide rod 26 through the second fixed rod 32. This pushes the high-temperature emulsion in the core area of ​​the vessel towards the cooling area of ​​the vessel wall, and pushes the emulsion near the wall surface back to the center area. This changes the heat transfer mode in the high-viscosity system in the later stage of the reaction from static heat conduction that depends on the thermal conductivity of the material to forced convection heat transfer that depends on macroscopic motion. This completely opens up the heat transfer path blocked by the high-viscosity material, eliminates the extreme temperature gradient between the cold wall surface and the hot core of the vessel, and effectively avoids the severe degradation of the product in the core of the vessel due to overheating.

[0037] Working principle: The first motor 23 is started, driving the rotating roller 24, which is fixedly connected to its output end, to rotate. The rotating roller 24 drives the stirring paddle 25 and guide rod 26 to rotate synchronously. The guide rod 26 drives the drive rod 29 to rotate via the push plate 27, the second fixed rod 32, the conversion plate 33, the first fixed rod 31, the fixed frame 30, and the sealing lifting sleeve 28. Because the drive guide groove 34 has an undulating trajectory in the circumferential direction, the drive rod 29 is forced to rise or fall by the trajectory of the drive guide groove 34 during rotation. The sealing lifting sleeve 28 slides and rises on the rotating roller 24, and the sealing lifting sleeve 28 drives the fixed frame 30 to move down synchronously. The fixed frame 30 transmits the lifting motion to the second fixed rod 32 through the first fixed rod 31 and the conversion plate 33. Since the height of the second fixed rod 32 is locked, the push plate 27 is driven to make regular reciprocating motion on the guide rod 26 through the second fixed rod 32, thereby pushing the high-temperature emulsion in the core area of ​​the vessel towards the cooling area of ​​the vessel wall, and pushing the emulsion near the wall that has cooled back to the center area; through the manual external water supply component, the cold Cooling water is simultaneously input from both the right inlet 19 and the left inlet 21. Cooling water enters the right distributor 5 and the left distributor 11 from the right inlet 19 and the left inlet 21, respectively. The right distributor 5 evenly distributes the cooling water to multiple right-side delivery pipes 8, and then the cooling water simultaneously enters the first cooling chamber 7 of each of the first annular cooling hoods 6. After flowing through, it converges from the left return pipe 10 into the left return device 9 and is discharged through the left outlet 20. Similarly, the left distributor 11 evenly distributes the cooling water to multiple left-side delivery pipes 14, and then the cooling water... Water simultaneously enters the second cooling chamber 13 of each of the second annular cooling hoods 12, flows through and merges into the right return pipe 16 into the right return device 15, and is discharged through the right outlet 22. Since the first annular cooling hood 6 and the second annular cooling hood 12 are alternately arranged in the vertical direction, the inlet and outlet of the adjacent cooling chambers are spatially complementary. When the heat exchange capacity of the outlet side of any cooling chamber decreases due to the cooling water absorbing heat along the way, the corresponding side of the adjacent cooling chamber is exactly the low temperature water inlet end, thereby achieving mutual compensation of cooling intensity in the axial and circumferential directions.
