Description

Technical Field

[0001] The invention relates to the technical field of polymerization reaction devices, in particular 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 a device used to synthesize bio-based polyamides. This device generally includes a reactor, 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, plant-derived monomers such as bio-based dibasic acids and diamines are generally used for polymerization reactions to produce degradable or environmentally friendly polyamide materials.

[0003] A Chinese patent with announcement number CN106268580B discloses a reactor, including a reactor body, a rotating shaft and a motor for driving the rotating shaft to rotate. The edge rotor inside the reactor can fully stir the unreacted substances at the edge of the reactor, so that the unreacted substances in the reactor can react more fully and evenly, and are easy to clean after the reaction.

[0004] A Chinese patent with announcement number CN118217916B discloses a chemical reactor, including a reactor body; the reactor body includes an outer reactor body; an inner reactor body is fixedly installed inside the outer reactor body, and an interlayer is provided between the inner reactor body and the outer reactor body; the invention is mainly used to solve the problem that the material in the middle of the reactor body is far from the interlayer, resulting in poor heating effect.

[0005] In the above-mentioned and similar prior arts, in large-scale production and processes requiring long-term stable heating, there is usually a jacket or coil outside the reactor to transfer heat to the material in the reactor through steam heating medium. However, due to the limited thermal conductivity of the heat wall, the external heating method has a relatively low heat transfer efficiency and a slow heating speed. The heat needs to be transferred to the reactants through the reactor wall, which may cause local uneven heating. Especially when the reactor design is imperfect or the heat medium flows unevenly, it is easy to cause poor product quality. At the same time, there will be a certain amount of energy loss and poor thermal efficiency. In addition, when the existing reactor is used for bio-based polyamide fiber polymerization, two raw materials are usually added to the reactor at the same time for reaction, which makes it difficult to fully mix the raw materials, reducing the stirring efficiency.

[0006] Therefore, the present invention provides a dynamic heating, stirring and mixing integrated reaction device capable of heating raw materials inside a reaction kettle and injecting two raw materials separately. Summary of the invention

[0033] In this embodiment, multiple groups of end covers 15 are fixedly installed on the outer side of the rotating shaft 4, and each group has two end covers 15. Multiple bevel gears 17 are fixedly installed on the outer side of the rotating shaft 4. The multiple bevel gears 17 are respectively located between the two end covers 15 of each group. An annular plate 16 is rotatably installed on the outer side of the two end covers 15 of each group through bearings. The end cover 15 and the annular plate 16 cooperate to form a sealed space. One end of the circular tube 136 away from the oblate tube 131 is installed on the inner side of the annular plate 16 through a bearing.

[0035] In this embodiment, a feeding cylinder 19 is fixedly installed on the top of the reactor 1, and a feeding hole 20 is opened through the inside of the feeding cylinder 19, and a feeding hole 22 is opened inside the rotating shaft 4. A plurality of feed holes 21 and discharge holes 23 are opened in a circular array inside the rotating shaft 4, and the feed hole 21 is located at the top of the reactor 1, and the discharge hole 23 is located on the inner side of the sealed space formed by the middle end cover 15 and the annular plate 16. The feed hole 21 is communicated with the discharge hole 23 and the feed hole 22, and a plurality of through holes 24 are opened through the inside of a group of circular tubes 136 near the middle, and a plurality of one-way plugs 25 are elastically connected to the inner wall of the circular tube 136, and the one-way plugs 25 are respectively located on the inner side of the through holes 24.

[0036] Specifically, the reactor 1 can provide a stable support for the feeding barrel 19, the feeding barrel 19 can provide a stable support for the driving motor, the feeding barrel 19 can provide a through-opening space for the feeding hole 20, and the feeding barrel 19 can provide a placement space for external liquid. The output end of the driving motor is connected to the rotating shaft 4 on the inner side of the feeding barrel 19, and the rotating shaft 4 can provide a through-opening space for the feeding hole 21, the feeding hole 22 and the discharge hole 23, so that the liquid inside the feeding barrel 19 enters the inner side of the feeding hole 22 through the feeding hole 21, and flows out from the discharge hole 23 to the liquid formed near the middle group of end covers 15. Inside the sealed space, the liquid then flows into one end of the loop tube 136 in the sealed space and enters the inner side of the middle loop tube 136. The elastic connection is an elastic rope connection. When the loop tube 136 rotates, the raw material pushes the one-way plug 25 under the action of the centrifugal force of the loop tube 136 and the atmospheric pressure, and the one-way plug 25 releases the seal on the through hole 24, so that the raw material passes through the through hole 24 and flows into the inner side of the reactor 1. Under the centrifugal action of the rotation of the loop tube 136, the raw material is sprayed in the reactor 1, so that the raw material in the feeding cylinder 19 is fully mixed with the raw material in the original reactor 1, thereby improving the mixing effect.

[0037] Working principle: When the staff uses the reactor 1, they first open the reactor 1, inject a raw material into the inside of the reactor 1, close the reactor 1, and start the driving motor to drive the rotating shaft 4 to rotate, so that the rotating shaft 4 drives the stirring rod 5 to rotate for stirring, and the rotating shaft 4 drives the outer spur gear 1 7 to rotate forward, so that the spur gear 1 7 drives the two spur gears 2 9 to rotate in the opposite direction through the meshing action, and the gear ring 67 is driven to rotate in the opposite direction through the meshing action of the spur gear 2 9, so that the gear ring 67 drives the movable cylinder 64 to rotate in the opposite direction under the support of the fixed ring 61 and the ball, and when the movable cylinder 64 rotates, the movable cylinder 64 drives the oblate tubes 131 on both sides to rotate, so that the oblate tubes 131 rotate in the opposite direction, and at the same time the oblate tubes 131 drive the round tubes 136 to rotate in the opposite direction, so that the rotation direction of the stirring rod 5 is opposite to that of the round tubes 136, and the inside of the stirring kettle is fully stirred by the two opposite rotation directions, and when the round tubes 136 rotate driven by the oblate tubes 131, the round tubes 136 rotate by the meshing action of the bevel gear 2 18 and the bevel gear 1 17, so that the revolution direction of the round tubes 136 is opposite to the rotation direction of the stirring rod 5 and the round tubes 136 rotate at the same time, thereby improving the stirring efficiency; Then the staff starts the heater 10, so that the heater 10 heats the hot oil and then outputs it from the output pipe 11. The hot oil enters the inner side of the middle chamber between the partition 1 65 and the partition 2 66 under the action of the heater 10, and then the hot oil passes through the oil delivery pipe 132 and enters the inner side of the flat round tube 131 near the front, and enters the inner side of the top and bottom circular tubes 136 under the transportation of the flat round tube 131. The hot oil enters the sealed space formed by the end cover 15 through the flat round tube 131 on the front, and then enters the inner side of the flat round tube 131 on the back. The hot oil flows upward from the oblate tube 131 on the back side to the inner side of the lower chamber formed by the bottom of the movable cylinder 64 and the second partition plate 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 oblate tube 131 and the round tube 136, the heat is transferred to the oblate tube 131 and the round tube 136, so that the oblate tube 131 and the round tube 136 heat the inner side of the stirring tank during the stirring process, which facilitates the uniform heating of the raw materials inside the stirring tank, thereby improving the reaction efficiency; Then the staff injects another raw material into the adding barrel 19 through the adding hole 20, so that the raw material is stored in the adding barrel 19, and the raw material in the adding barrel 19 enters the inner side of the feeding hole 22 through the feeding hole 21, and enters the inner side of the sealed space formed by the end cover 15 through the discharging hole 23 under the conveying action of the feeding hole 22, so that the raw material inside the sealed space enters the inner side of the two middle return tubes 136, when the return tubes 136 rotate, the raw material pushes the one-way plug 25 open under the action of the centrifugal force of the return tube 136 and the atmospheric pressure, releases the sealing of the through hole 24 by the one-way plug 25, and makes the raw material pass through the through hole 24 and flow into the inner side of the reactor 1, and under the centrifugal action of the rotation of the return tube 136, the raw material is sprayed in the reactor 1, so that the raw material in the adding barrel 19 is fully mixed with the raw material in the original reactor 1, thereby improving the mixing effect; After the reaction is completed, the drive motor is turned off. At this time, the one-way plug 25 seals the through hole 24 under the action of the elastic component to prevent the raw materials from flowing back into the middle circular tube 136. After all the products after the reaction have flowed out, the staff can inject cleaning water into the inner side of the feeding tube 19 through the feeding hole 20, start the drive motor to drive the circular tube 136 to rotate, so that the middle circular tube 136 sprays the cleaning water onto the inner wall of the reactor 1, which can not only clean the inner side of the feeding tube 19, the feeding hole 22 and the circular tube 136, but also facilitate the cleaning of the inner wall of the reactor 1, thereby improving the cleaning effect.
