Description

Technical Field

[0001] The present invention relates to the technical field of polymerization reaction devices, and particularly to a dynamic heating, stirring and mixing integrated reaction device. Background Art

[0002] A dynamic heating, stirring and mixing integrated reaction device generally refers to equipment used for synthesizing bio-based polyamides. Such equipment usually includes a reaction kettle, a heating device, a cooling system, a stirring device, a vacuum system, etc., which are used to control the temperature, pressure and reaction time of the polymerization reaction to achieve an efficient polymerization reaction. In the production process of bio-based polyamides, monomers derived from plants such as bio-based dicarboxylic acids and diamines are usually used for polymerization reaction to produce degradable or environmentally friendly polyamide materials.

[0003] The Chinese patent with the publication number CN106268580B discloses a reaction kettle, which includes a kettle body, a rotating shaft and a motor for driving the rotation of the rotating shaft. The edge rotator inside the reaction kettle can fully stir the substances that have not been fully reacted at the edge of the reaction kettle, making the unreacted substances in the reaction kettle react more fully and evenly, and facilitating cleaning after the reaction.

[0004] The Chinese patent with the publication number CN118217916B discloses a chemical reaction kettle, which includes a reaction kettle body; the reaction kettle body includes an outer kettle body; an inner kettle body is fixedly installed inside the outer kettle body, and there is an interlayer between the inner kettle body and the outer kettle body; this invention is mainly used to solve the problem that the materials in the middle of the kettle body are far from the interlayer, resulting in poor heat reception effect.

[0005] In the above-mentioned and similar prior arts, in large-scale production and processes that require long-term stable heating, there is usually a jacket or coil outside the reaction kettle, and heat is transferred to the materials inside the reaction kettle through a steam heating medium. However, due to the limited thermal conductivity of the hot wall, the heat transfer efficiency of the external heating method is relatively low, and the heating speed is slow. The heat needs to be transferred to the reactants through the reaction kettle wall, and local heating unevenness may occur. Especially when the design of the reaction kettle is imperfect or the flow of the heat medium is uneven, it is easy to lead to poor product quality, and there will also be a certain amount of energy loss, with poor thermal efficiency. Moreover, when the existing reaction kettle is used for the polymerization reaction of bio-based polyamide fibers, usually two raw materials are added to the reaction kettle at the same time for reaction, and the raw materials are difficult to be fully mixed, reducing the stirring efficiency.

[0006] Therefore, the present invention provides a dynamic heating, stirring and mixing integrated reaction device that can heat the raw materials on the inner side of the reaction kettle and inject the two raw materials separately. Summary of the Invention

An oil delivery mechanism 6 is arranged on the inner side of the top wall of the reaction kettle 1. The oil delivery mechanism 6 is assembled to transport and recover the hot oil heated by the heater 10 through the movable cylinder 64, the first partition 65 and the second partition 66; the oil delivery mechanism 6 includes a movable cylinder 64 rotatably arranged on the inner side of the top wall of the reaction kettle 1. The first partition 65 and the second partition 66 are rotatably installed inside the movable cylinder 64 through bearings. The oil delivery mechanism 6 further includes a fixed ring 61. The fixed ring 61 is fixedly installed on the inner side of the top wall of the reaction kettle 1. A connecting ring 62 is rotatably installed inside the fixed ring 61 through a bearing. First rolling grooves 63 are respectively opened on the sides of the fixed ring 61 and the connecting ring 62 close to each other. A plurality of rolling balls are placed inside the first rolling grooves 63. The inner side of the fixed ring 61 is fixedly connected to the outer side of the movable cylinder 64. A toothed ring 67 is fixedly installed on the inner side of the movable cylinder 64 near the top.

[0034] Specifically, the reaction kettle 1 can provide a rotating through - space for the rotating shaft 4, and the reaction kettle 1 can provide a stable support for the heater 10. The heater 10 can heat the hot oil and output the heated hot oil through the output pipe 11, and recycle it through the input pipe 12 for re - heating. The movable cylinder 64 can provide a stable support for the toothed ring 67. After the toothed ring 67 is acted on by an external force, it can drive the movable cylinder 64 to rotate. The movable cylinder 64 can provide a rotating support for the partition plate 1 65 and the partition plate 2 66 through bearings. The partition plate 1 65 and the partition plate 2 66 can rotate relative to the rotating shaft 4 through bearings, so that the rotating shaft 4 can rotate relative to the partition plate 1 65 and the partition plate 2 66. The reaction kettle 1 can provide a stable support for the fixed ring 61. The fixed ring 61 can provide a rotating support for the connecting ring 62 through a rolling groove and a rolling ball. The connecting ring 62 can provide a stable support for the movable cylinder 64, so that the movable cylinder 64 can rotate stably under the support of the fixed ring 61 through the connecting ring 62.

[0035] In this embodiment, an oil - conveying mechanism 13 is arranged at the bottom of the movable cylinder 64. The oil - conveying mechanism 13 is assembled to convey hot oil through an oval tube 131 and a rotating coiled tube 136 to uniformly heat and stir the inner side of the reaction kettle 1. The oil - conveying mechanism 13 includes two oval tubes 131, and one ends of the two oval tubes 131 are respectively fixedly installed on both sides of the movable cylinder 64. A plurality of groups of coiled tubes 136 are rotatably installed on the sides of the two oval tubes 131 close to each other through bearings and are arranged in sequence from top to bottom. The middle group of the coiled tubes 136 is not communicated with the oval tube 131, and the rest of the coiled tubes 136 are all communicated with the oval tube 131. The coiled tubes 136 and the stirring rods 5 are distributed alternately in an array.

[0036] Specifically, the oval tube 131 can reduce the resistance during rotation through the arc surfaces on both sides of itself. The movable cylinder 64 can provide a stable support for the oval tube 131. When the movable cylinder 64 rotates, it can drive the two oval tubes 131 to rotate simultaneously. The oval tube 131 can provide a rotating support for the coiled tube 136 through a bearing, so that the oval tube 131 can drive the coiled tube 136 to revolve. At the same time, the coiled tube 136 can independently rotate through a bearing. The two groups of coiled tubes 136 near the top and the bottom are communicated with the oval tube 131 for transporting hot oil, and the middle coiled tube 136 is not communicated with the oval tube 131 for feeding work, so that the subsequent added raw materials can be between the upper and lower heat sources. Under the agitation of the self - rotation of the coiled tube 136 itself, the subsequent added raw materials can be fully mixed with the initial raw materials and can be evenly heated at the same time.

[0037] In this embodiment, a plurality of support rods 2 are fixedly installed at the bottom of the reaction kettle 1. The top of the support rod 2 is fixedly installed with a support platform 3. One end of the rotating shaft 4 is fixedly connected to the driving motor at the top of the reaction kettle 1, and the other end of the rotating shaft 4 is rotatably installed on the top of the support platform 3 through a bearing. The ends of the two oval tubes 131 away from the movable cylinder 64 are fixedly installed with a rotating box 133. The rotating box 133 is rotatably installed on the outer side of the rotating shaft 4 through a bearing. An annular groove 134 is formed inside the rotating box 133. Oil through holes 135 are respectively formed on both sides of the rotating box 133. The oval tube 131 communicates with the annular groove 134 through the oil through holes 135. The bottom of the rotating box 133 is rotatably installed on the outer side of the support platform 3 through a bearing. Rolling grooves two 14 are respectively formed on the sides of the rotating box 133 and the support platform 3 close to each other. A plurality of rolling balls are placed inside the rolling grooves two 14.

[0038] Specifically, the reaction kettle 1 can provide stable support for the support platform 3 through the support rods 2. The support platform 3 can provide rotational support for one end of the rotating shaft 4 through the bearing. The support platform 3 can provide stable support for the rotating box 133 through the rolling grooves two 14 and the rolling balls. The rotating box 133 can provide rotational support for one end of the oval tube 131, making the rotation of the oval tube 131 more stable. At the same time, the rotating box 133 can provide a space for forming the annular groove 134 and the oil through holes 135. The annular groove 134 and the oil through holes 135 can provide a flow channel for the hot oil, facilitating the hot oil to flow from the oil through hole 135 on one side to the other side, thereby providing a recovery channel for the recovery of the hot oil.

[0039] In this embodiment, a first spur gear 7 is fixedly installed on the outer side of the rotating shaft 4, and the first spur gear 7 is located on the top of the first partition 65. Two support columns 8 are fixedly installed on the inner side of the top wall of the reaction kettle 1. The support columns 8 penetrate through the interiors of the first partition 65 and the second partition 66. A second spur gear 9 is fixedly installed on the outer side of the support columns 8, and the two second spur gears 9 are respectively meshed with the first spur gear 7 and the toothed ring 67.

[0040] Specifically, the rotating shaft 4 can provide stable support for the first spur gear 7. The reaction kettle 1 can provide stable support for the support columns 8. The support columns 8 can provide stable support for the first partition 65 and the second partition 66. At the same time, the support columns 8 can provide rotational support for the second spur gears 9, ensuring that the first spur gear 7 and the second spur gears 9 are fully meshed. The meshing of the first spur gear 7 and the second spur gears 9 results in opposite rotation directions. The meshing of the second spur gears 9 and the toothed ring 67 can ensure that the rotation direction of the toothed ring 67 is opposite to that of the rotating shaft 4, thereby realizing that the rotation direction of the movable cylinder 64 is opposite to that of the rotating shaft 4.

[0041] In this embodiment, the first partition plate 65 and the second partition plate 66 divide the movable cylinder 64 into upper, middle, and lower chambers. The end of the output pipe 11 away from the heater 10 penetrates the inner side of the first partition plate 65 and communicates with the middle chamber. The end of the input pipe 12 away from the heater 10 penetrates the inside of the first partition plate 65 and the second partition plate 66 and communicates with the lower chamber. One end of an oval pipe 131 communicates with the lower chamber, and the top of the other oval pipe 131 is fixedly communicated with an oil delivery pipe 132. The end of the oil delivery pipe 132 away from the oval pipe 131 is fixedly installed on one side of the movable cylinder 64, and the oil delivery pipe 132 communicates with the middle chamber.

[0042] Specifically, the upper chamber formed by the first partition plate 65 and the second partition plate 66 can provide a moving space for the first spur gear 7 and the second spur gear 9. The middle chamber can provide a placement space for the hot oil in the input pipe 12, so that the hot oil flowing out of the heater 10 enters the middle chamber through the output pipe 11 and flows into the oil delivery pipe 132 from the middle chamber. The lower chamber can provide a placement space for the recycled hot oil, so that the hot oil flows into the lower chamber from the oval pipe 131 and flows back to the heater 10 through the input pipe 12 from the lower chamber, so that the outflow and return of the hot oil do not affect each other.

[0043] In this embodiment, multiple groups of end caps 15 are fixedly installed on the outer side of the rotating shaft 4. Each group has two end caps 15. A plurality of first bevel gears 17 are fixedly installed on the outer side of the rotating shaft 4. The plurality of first bevel gears 17 are respectively located between the two end caps 15 of each group. The outer sides of the two end caps 15 of each group are rotatably installed with an annular plate 16 through bearings. The end cap 15 and the annular plate 16 cooperate to form a sealed space. One end of the return pipe 136 away from the oval pipe 131 is installed through the inner side of the annular plate 16 through a bearing. A second bevel gear 18 is fixedly installed on the outer side of one end of the return pipe 136 located inside the annular plate 16, and the second bevel gear 18 meshes with the first bevel gear 17.

[0044] Specifically, the rotating shaft 4 can provide a stable support for the end cap 15. The end cap 15 can cooperate with the annular plate 16 through bearings to form a sealed space. The sealed spaces formed by the two groups of end caps 15 near the top and bottom can provide a placement space for the hot oil, so that the hot oil circulates for recycling. The sealed space formed by the group of end caps 15 near the middle can provide a placement space for the external liquid. The annular plate 16 can provide a rotating support for one end of the return pipe 136 through bearings. At the same time, the sealed space formed by the end cap 15 and the annular plate 16 can provide a meshing space for the meshing of the first bevel gear 17 and the second bevel gear 18.

[0045] In this embodiment, a feeding cylinder 19 is fixedly installed at the top of the reaction kettle 1. A feeding hole 20 is formed through the inside of the feeding cylinder 19. A feeding hole 22 is formed in the inside of the rotating shaft 4. A plurality of feeding holes 21 and discharging holes 23 are formed in a circumferential array inside the rotating shaft 4. The feeding hole 21 is located at the top of the reaction kettle 1, and the discharging hole 23 is located inside the sealed space formed by the middle end cap 15 and the annular plate 16. The feeding hole 21 and the discharging hole 23 communicate with the feeding hole 22. A plurality of through holes 24 are formed through the inside of the innermost set of return pipes 136. A plurality of one-way plugs 25 are elastically connected to the inner wall of the return pipe 136, and the one-way plugs 25 are respectively located inside the through holes 24.

[0046] Specifically, the reaction kettle 1 can provide stable support for the feeding cylinder 19. The feeding cylinder 19 can provide stable support for the driving motor. The feeding cylinder 19 can provide a space for the feeding hole 20 to be formed through. The feeding cylinder 19 can provide a placement space for the external liquid. The output end of the driving motor is in transmission connection with the rotating shaft 4 inside the feeding cylinder 19. The rotating shaft 4 can provide a space for the feeding hole 21, the feeding hole 22 and the discharging hole 23 to be formed through, so that the liquid inside the feeding cylinder 19 enters the inside of the feeding hole 22 through the feeding hole 21 and flows out from the discharging hole 23 to the inside of the sealed space formed by the middle end cap 15. Subsequently, the liquid flows into one end of the return pipe 136 inside the sealed space and enters the inside of the middle return pipe 136. The elastic connection is a connection by an elastic cord. When the return pipe 136 rotates, the raw materials are pushed open the one-way plugs 25 under the action of the centrifugal force of the return pipe 136 and the atmospheric pressure, releasing the sealing of the through holes 24 by the one-way plugs 25, so that the raw materials flow through the through holes 24 into the inside of the reaction kettle 1. Under the action of the self-rotation centrifugation of the return pipe 136, the raw materials are sprayed in the reaction kettle 1, so that the raw materials in the feeding cylinder 19 are fully mixed with the raw materials in the original reaction kettle 1, improving the mixing effect.

[0047] Working principle: When using the reactor 1, the staff first opens the reactor 1, injects a raw material into the inner side of the reactor 1, closes the reactor 1, and then starts the driving motor to drive the rotating shaft 4 to rotate. The rotating shaft 4 drives the stirring rod 5 to rotate for stirring. The rotating shaft 4 drives the spur gear one 7 on the outside to rotate forward, and the spur gear one 7 drives the two spur gears two 9 to rotate in the opposite direction through meshing. Through the meshing of the spur gears two 9, the toothed ring 67 is driven to rotate in the opposite direction, and the toothed ring 67 drives the movable cylinder 64 to rotate in the opposite direction under the support of the fixed ring 61 and the rolling balls. When the movable cylinder 64 rotates, the movable cylinder 64 drives the oval tubes 131 on both sides to rotate, making the oval tubes 131 rotate in the opposite direction. At the same time, the oval tubes 131 drive the return tubes 136 to rotate in the opposite direction, making the rotation direction of the stirring rod 5 opposite to that of the return tubes 136. The opposite rotation directions of the two are used to fully stir the inner side of the stirring kettle. When the return tubes 136 rotate driven by the oval tubes 131, the return tubes 136 achieve self-rotation through the meshing of the bevel gear two 18 and the bevel gear one 17. Thus, while the revolution direction of the return tubes 136 is opposite to the rotation direction of the stirring rod 5, they also perform self-rotation, improving the stirring efficiency;

[0048] Subsequently, the staff starts the heater 10, and the heater 10 heats the hot oil and outputs it from the output pipe 11. Under the action of the heater 10, the hot oil enters the inner side of the middle chamber between the partition one 65 and the partition two 66. Subsequently, the hot oil passes through the oil delivery pipe 132 and enters the inner side of the oval tube 131 near the front. Under the conveyance of this oval tube 131, it enters the inner sides of the top and bottom return tubes 136. The hot oil enters the sealed space formed by the end cap 15 through the oval tube 131 in the front, and then enters the inner side of the oval tube 131 in the back, making the hot oil flow upward from the oval tube 131 in the back into the inner side of the lower chamber formed by the bottom of the movable cylinder 64 and the partition two 66, and then flows back to the inner side of the heater 10 through the input pipe 12. The heater 10 circulates and heats the hot oil, so that when the hot oil flows inside the oval tubes 131 and the return tubes 136, it transfers heat to the oval tubes 131 and the return tubes 136, enabling the oval tubes 131 and the return tubes 136 to heat the inner side of the stirring kettle during the stirring process, facilitating uniform heating of the raw materials inside the stirring kettle, and thus providing the reaction efficiency;

[0049] Subsequently, the staff injects another raw material into the feeding cylinder 19 through the feeding hole 20, stores the raw material in the feeding cylinder 19. The raw material in the feeding cylinder 19 enters the inner side of the feeding hole 22 through the feeding hole 21, and under the conveying action of the feeding hole 22, passes through the discharging hole 23 and enters the inner side of the sealed space formed by the end cover 15 in the middle, so that the raw material inside the sealed space enters the inner sides of the two middle return pipes 136. When the return pipe 136 rotates, the raw material pushes open the one-way plug 25 under the action of the centrifugal force of the return pipe 136 and the atmospheric pressure, releases the sealing of the through hole 24 by the one-way plug 25, and enables the raw material to flow into the inner side of the reaction kettle 1 through the through hole 24. Under the action of the self-rotation centrifugation of the return pipe 136, the raw material is sprayed in the reaction kettle 1, so that the raw material in the feeding cylinder 19 is fully mixed with the raw material in the original reaction kettle 1, improving the mixing effect;

[0050] After the reaction is completed, the driving motor is turned off. At this time, the one-way plug 25 seals the through hole 24 under the action of the elastic component, preventing the raw material from flowing back into the middle return pipe 136. After all the reaction products have flowed out, the staff can inject cleaning water into the inner side of the feeding cylinder 19 through the feeding hole 20, start the driving motor to drive the return pipe 136 to rotate, and make the middle return pipe 136 spray the cleaning water onto the inner wall of the reaction kettle 1. This can not only clean the inner sides of the feeding cylinder 19, the feeding hole 22 and the return pipe 136, but also facilitate the cleaning of the inner wall of the reaction kettle 1, improving the cleaning effect.
