AI Technical Summary
Existing hydrogenated nitrile rubber hydrogenation reactors suffer from poor hydrogen dispersion in high-viscosity solutions, resulting in limited gas-liquid contact area, low mixing catalytic efficiency, long hydrogenation reaction time, uneven hydrogenation degree of the product, and impact on product performance stability.
The system employs a low-speed, high-torque rotating mechanism and a jet assembly working in tandem. The stirring assembly and jet assembly are driven by a drive motor. Hydrogen gas is distributed through a multi-stage rotating ventilation ring and an explosion-proof steel pipe before being ejected from a high-pressure nozzle, forming a large number of fine bubbles that are evenly dispersed. Combined with the macroscopic flow field disturbance of the stirring blades, this improves the gas-liquid contact area and catalytic efficiency.
It significantly improves the mixing uniformity of hydrogen and nitrile rubber solution and the catalytic reaction efficiency, shortens the hydrogenation reaction time, improves the uniformity of hydrogenation degree and batch consistency of products, and reduces equipment load and safety risks.

Abstract
Description
Technical Field
[0001] This invention relates to the field of polymer material production equipment technology, specifically to a polymer material production and processing apparatus. Background Technology
[0002] Hydrogenated nitrile butadiene rubber (NBR) hydrogenation reactors are specialized sealed pressure vessels that catalytically hydrogenate nitrile butadiene rubber (NBR) under high temperature and pressure conditions by introducing hydrogen into the solution. The core principle involves dissolving NBR into a gel solution using solvents such as chlorobenzene. Under the action of rhodium or palladium catalysts, the carbon-carbon double bonds on the butadiene segments are selectively hydrogenated to saturation, while the cyano groups of the acrylonitrile units remain unaffected. The reaction is typically carried out at 120-150°C and 6-12 MPa pressure for 6-10 hours, achieving a degree of hydrogenation exceeding 80%. The reactors are equipped with jacketed heating, magnetic stirring, PID temperature and pressure control, and safety devices such as rupture discs. The materials used are primarily 316L stainless steel or nickel-based alloys to ensure corrosion resistance and sealing safety. The hydrogenated NBR retains its oil resistance while significantly improving its heat resistance, ozone resistance, and chemical resistance, making it widely used in high-end applications such as automotive seals and oil well tools.
[0003] In existing technologies, although traditional hydrogenation reactors for hydrogenated nitrile butadiene rubber (NBR) have stirring functions, they generally employ a method of directly introducing hydrogen into the NBR solution and then relying on mechanical stirring to achieve gas-liquid mixing. Due to the high viscosity of the NBR solution, hydrogen dispersibility in the high-viscosity solution is extremely poor, making it difficult to form uniform and fine bubbles. The gas-liquid contact area is very limited, and the catalytic reaction mainly relies on occasional contact between the bubble surface and the catalyst. This results in significantly low mixing and catalytic efficiency. To achieve the target degree of hydrogenation, the reaction time often needs to be extended to 8–12 hours or even longer. This not only drastically reduces production efficiency but also exacerbates equipment load and safety risks due to prolonged high-temperature and high-pressure operation. Furthermore, uneven hydrogen distribution can easily lead to localized over- or under-hydrogenation, resulting in poor uniformity of hydrogenation and difficulty in ensuring batch consistency. Ultimately, this affects the stability of the mechanical properties and weather resistance of the hydrogenated NBR. Therefore, those skilled in the art provide a polymer material production and processing device to solve the problems mentioned in the background art. Summary of the Invention

Detailed Implementation
[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0025] Please see Figures 1-4 As shown, the present invention provides a technical solution: a polymer material production and processing apparatus, comprising a storage component 1 for storing nitrile rubber, a stirring component 2 for stirring the nitrile rubber located at the lower part of the storage component 1, a gas transmission component 3 for filling the nitrile rubber with hydrogen gas located at the upper center of the storage component 1, a plurality of jetting components 7 for uniformly filling the nitrile rubber with hydrogen gas located at the lower center of the storage component 1, a low-speed high-torque rotating mechanism 6 for driving the plurality of jetting components 7 to rotate uniformly within the nitrile rubber located at the center of the storage component 1, a positioning component 5 for stably installing the low-speed high-torque rotating mechanism 6 located at the upper end of the low-speed high-torque rotating mechanism 6, and a driving component 4 for driving the low-speed high-torque rotating mechanism 6 to operate located at the upper center of the storage component 1.
[0026] This hydrogenated nitrile rubber hydrogenation reactor uses a drive motor 106 to simultaneously drive two systems: the stirring assembly 2 and the jetting assembly 7. The drive motor 106 drives the drive shaft 201 to rotate. The drive shaft 201 drives the stirring blades 204 to macroscopically stir the high-viscosity nitrile rubber solution. On the other hand, it transmits power to the drive bevel gear ring 404 through the fixed rod 401, the reinforcing sleeve 402, and the connecting rod 403. The drive bevel gear ring 404 meshes with the transmission helical gear 6016, and the power is transmitted to the worm gear 6012 through the second transmission shaft 6013, the transmission wheel 6014, the transmission belt 6015, and the first transmission shaft 6011. The worm gear 6012 and the worm... The helical gear of wheel 608 drives the hollow tube 607 and the jet assembly 7 to rotate at low speed and high torque. Hydrogen gas passes through the main intake pipe 302, the first rotating venting ring 301, the first explosion-proof steel pipe 303, the explosion-proof pipe 304, the second rotating venting ring 305, the second explosion-proof steel pipe 306, the third explosion-proof steel pipe 606, the third rotating venting ring 605, the fourth explosion-proof steel pipe 6010, and the explosion-proof bend 701, and is finally ejected from the high-pressure nozzle 702. Under the action of low speed and high torque rotation, the hydrogen gas is cut into a large number of micro bubbles and evenly dispersed in the high-viscosity liquid. This fundamentally and effectively solves the problems of small gas-liquid contact area, low mixing catalytic efficiency, and uneven hydrogenation in traditional methods.
[0027] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, the material storage assembly 1 includes several support legs 101. The upper ends of the support legs 101 are fixedly connected to a base 102. A discharge pipe 103 is fixedly sleeved on one side of the center of the drive shaft 201. A knife gate valve 104 is fixedly connected to the discharge port on one end of the discharge pipe 103. A barrel 105 is fixedly connected to the upper center of the base 102 near the edge. A drive motor 106 is fixedly connected to the upper center of the barrel 105. The rotating end of the drive motor 106 at the lower end passes through the upper end of the barrel 105 and leads to the interior of the barrel 105.
[0028] Support leg 101 provides stable ground support for the entire reactor. Base 102 serves as the basic support platform for material storage assembly 1. The barrel 105 is fixed to the upper center near the edge of the base 102 to form a sealed reaction chamber for containing nitrile rubber solution. Drive motor 106 is installed at the upper center of barrel 105, with its rotating end extending downward through barrel 105 into the interior, providing the core power source for stirring assembly 2 and subsequent transmission system. Feed pipe 103 is fixedly sleeved inside drive shaft 201 at the center near one side, forming an internal channel through drive shaft 201. Nitrile rubber raw material can enter the interior of barrel 105 through this pipe. Knife gate valve 104 is installed at the outlet of feed pipe 103, controlling the flow and interruption of raw material by opening and closing to achieve precise feeding. The material storage assembly 1 as a whole constitutes the main body of the reactor for material storage and pressure bearing, providing a sealed and controllable reaction environment for hydrogenation reaction.
[0029] As one implementation method in this embodiment, please refer to Figure 5 As shown, the stirring assembly 2 includes a drive shaft 201. The lower end of the drive shaft 201 is rotatably sleeved on the center of the lower inner wall of the base 102 via a bearing. The upper end of the drive shaft 201 is fixedly connected to the rotating end of the drive motor 106. Several positioning rings 203 are fixedly connected to the lower part of the outer center of the drive shaft 201. Several stirring blades 204 are fixedly connected to the outer side of the several positioning rings 203 in a ring-shaped arrangement at equal intervals.
[0030] The lower end of the drive shaft 201 is rotatably connected to the center of the inner wall of the base 102 via a bearing, and the upper end is fixedly connected to the rotating end of the drive motor 106. When the drive motor 106 is running, it directly drives the drive shaft 201 to rotate around the central axis. The positioning ring 203 is fixed at the lower center of the outer side of the drive shaft 201. Several stirring blades 204 are arranged in a ring at equal intervals and fixed outside the positioning ring 203. When the drive shaft 201 rotates, the stirring blades 204 move in a circular motion in the nitrile rubber solution inside the barrel 105, generating a strong shearing and mixing effect on the high-viscosity rubber solution, preventing local deposition of the rubber solution, and providing macroscopic flow field disturbance for the hydrogen ejected by the subsequent jet assembly 7, so that the microbubbles can further diffuse in the stirring flow field, avoiding the aggregation and floating of bubbles, and significantly increasing the effective contact time and contact area between hydrogen and rubber solution.
[0031] As one implementation method in this embodiment, please refer to Figure 6 As shown, the gas transmission assembly 3 includes a first rotating vent ring 301, which is fixedly connected to the inner wall of the barrel 105 near the edge. The air inlet end of the first rotating vent ring 301 near one side is fixedly connected to a main air inlet pipe 302. The input end of the main air inlet pipe 302 passes through the inner wall of the barrel 105 and leads to the outside of the barrel 105. Multiple gas output ends near the lower part of the first rotating vent ring 301 are fixedly connected to first explosion-proof steel pipes 303. The output ends near the lower part of the multiple first explosion-proof steel pipes 303 are fixedly connected to connecting rods 403. The lower ends of multiple explosion-proof pipes 304 are fixedly connected to a second rotating vent ring 305. Multiple gas input ends near the upper part of the second rotating vent ring 305 are fixedly connected to the gas output ends of the multiple explosion-proof pipes 304. Multiple gas output ends near the lower part of the second rotating vent ring 305 are fixedly connected to second explosion-proof steel pipes 306.
[0032] The main inlet pipe 302 passes through the inner wall of the barrel 105 and leads to the outside, for connecting to a high-pressure hydrogen source. Its upper center inlet, located on one side, is fixedly connected to a first rotating vent ring 301. The first rotating vent ring 301 is installed on the inner wall of the barrel 105 near its edge and rotates synchronously with the rotating components inside the barrel 105, achieving sealed ventilation between the stationary pipe and the rotating components. After hydrogen enters the first rotating vent ring 301, it flows through multiple gas outlets at its lower end into multiple first explosion-proof steel pipes 303. The first explosion-proof steel pipes 303 extend downwards and connect to an explosion-proof pipe 304 via a connecting rod 403. The lower end of the explosion-proof pipe 304 is connected to the second rotating vent ring 305. Multiple gas inlets at the upper part of the second rotating vent ring 305 receive hydrogen from the explosion-proof pipe 304, and then flow into multiple second explosion-proof steel pipes 306 through multiple gas outlets at the lower part of the second rotating vent ring 305. The second explosion-proof steel pipes 306 extend downward to transport hydrogen to the third explosion-proof steel pipe 606 inside the low-speed high-torque rotating mechanism 6. The gas transmission component 3 achieves a multi-stage sealed transition of hydrogen from the stationary inlet pipe to the high-speed rotating jet system through two-stage rotating vent rings, ensuring that hydrogen does not leak during transmission. At the same time, the multi-path distribution ensures that hydrogen is evenly distributed to each jet component 7.
[0033] As one implementation method in this embodiment, please refer to Figure 4 As shown, the drive assembly 4 includes multiple fixing rods 401, which are fixedly connected to the upper outer center of the drive shaft 201. Each of the drive shafts 201 has a reinforcing sleeve 402 fixedly connected to its opposite ends. The reinforcing sleeves 402 are fixedly fitted onto the joints of the multiple first explosion-proof steel pipes 303 and the multiple explosion-proof pipes 304. Each of the reinforcing sleeves 402 has a connecting rod 403 fixedly connected to its opposite ends. The lower end of the connecting rod 403 on the side away from the reinforcing sleeve 402 is fixedly connected to a drive bevel gear ring 404.
[0034] Multiple fixing rods 401 are fixed to the upper outer center of the drive shaft 201 and rotate synchronously with the drive shaft 201. The ends of each fixing rod 401 that are far apart from each other are fixedly connected to a reinforcing sleeve 402. The reinforcing sleeve 402 is fixedly fitted at the joint of the first explosion-proof steel pipe 303 and the explosion-proof pipeline 304, which not only serves to reinforce the pipeline and prevent vibration, but also transmits the rotational power of the drive shaft 201 to the joint. The ends of each reinforcing sleeve 402 that are far apart from each other are fixedly connected to a connecting rod 403. The lower end of the connecting rod 403 is fixedly connected to a drive bevel gear ring 404. When the drive shaft 201 rotates, the fixed rod 401, the reinforcing sleeve 402, and the connecting rod 403 transmit torque in sequence, driving the bevel gear ring 404 to revolve around the central axis at the same speed as the drive shaft 201. The bevel teeth on the outer edge of the drive bevel gear ring 404 mesh with the transmission helical gear 6016, converting the revolution power into the rotation power of the transmission helical gear 6016, thereby starting the transmission chain of the entire low-speed high-torque rotating mechanism 6. The drive assembly 4 cleverly utilizes the main rotational power of the drive shaft 201 to provide driving force for the rotation of the jet assembly 7 through a purely mechanical transmission method, without the need for an additional power source, resulting in a compact structure and reliable transmission.
[0035] As one implementation method in this embodiment, please refer to Figure 4 As shown, the positioning component 5 includes a reinforcing ring 501, which is fixedly sleeved inside the barrel 105 at the upper center. Multiple reinforcing rods 502 are fixedly connected to the inner wall of the reinforcing ring 501 in a ring-shaped arrangement at equal intervals.
[0036] The reinforcing ring 501 is fixedly sleeved inside the barrel 105 at the upper center, serving as the top support and positioning reference for the low-speed, high-torque rotating mechanism 6. Multiple reinforcing rods 502 are arranged equidistantly in a ring and fixed to the inner wall of the reinforcing ring 501. The lower ends of the sides that are close to each other are fixedly connected to the base plate 601. The reinforcing ring 501 and the reinforcing rods 502 together form a rigid frame, which stably suspends the low-speed, high-torque rotating mechanism 6 at the center position inside the barrel 105, preventing it from radially deviating or axially moving during rotation. At the same time, the ring structure of the reinforcing ring 501 provides an installation base for the third rotating vent ring 605, making the air passage connection between the end of the gas transmission component 3 and the jet component 7 stable and reliable, and ensuring the concentricity and sealing of each vent ring under high-speed rotation.
[0037] As one implementation method in this embodiment, please refer to Figure 7As shown, the low-speed, high-torque rotating mechanism 6 includes a base plate 601. The base plate 601 is fixedly connected to the lower end of one side of multiple reinforcing rods 502 that are close to each other. First lugs 602 are fixedly connected to both ends of the center of one side of the base plate 601. An extension plate 603 is fixedly connected to the center of the other side of the base plate 601. Second lugs 604 are fixedly connected to both sides of the lower center of the first lugs 602. A third rotating vent ring 605 is fixedly connected to the lower center of the base plate 601 near the edge. Multiple air inlets on the upper part of the third rotating vent ring 605 are fixedly connected to third explosion-proof steel pipes 606. Multiple third explosion-proof steel pipes 606 are respectively fixedly sleeved inside the base plate 601 near the center and edge. A hollow tube 607 is rotatably sleeved through a bearing at the lower center of the base plate 601. A worm gear 608 is fixedly sleeved on the outside of the hollow tube 607. Multiple positioning holes 609 are arranged equidistantly in a ring at the center of the worm gear 608 near the edge. Multiple gas outlets at the lower center of the third rotary vent ring 605 near the edge are fixedly connected to fourth explosion-proof steel pipes 6010. Multiple fourth explosion-proof steel pipes 6010 are respectively fixedly sleeved inside the positioning holes 609. The inner center of the two first lugs 602 is rotatably sleeved with a first drive shaft 6011 through bearings. A worm gear 6012 is fixedly sleeved on one end of the outer side of the first drive shaft 6011. The worm gear 6012 and the worm wheel 608 are connected by helical gear transmission. The inner center of the two second drive shafts 6013 are rotatably sleeved with bearings. A drive wheel 6014 is fixedly sleeved on one end of the outer side of both the first drive shaft 6011 and the second drive shaft 6013. A drive belt 6015 is sleeved on the outer side of the two drive wheels 6014. A drive helical gear 6016 is fixedly connected to the end of the second drive shaft 6013 away from the drive belt 6015. The drive helical gear 6016 and the drive bevel gear ring 404 are connected by gear meshing transmission.
[0038] The base plate 601 is fixed to the lower end of multiple reinforcing rods 502, serving as the core support plate of the entire rotating mechanism. The first lug 602 is fixed to the center of one side of the base plate 601 near both ends. The second lug 604 is fixed to the lower center of the first lug 602 near both sides. The first drive shaft 6011 is rotatably connected to the center of the two first lugs 602 via bearings, allowing it to rotate freely around its own axis. The extension plate 603 is fixed to the center of the other side of the base plate 601 to balance the centrifugal force during rotation. The third rotating vent ring 605 is fixed... At the lower center near the edge of the substrate 601, multiple air inlets at the upper part are connected to the gas passage inside the substrate 601 via a third explosion-proof steel pipe 606 to receive hydrogen from the gas transmission component 3. Multiple gas outlets at the lower center near the edge of the substrate 601 deliver hydrogen downwards via a fourth explosion-proof steel pipe 6010. A hollow tube 607 is rotatably sleeved inside the substrate 601 at the lower center via a bearing, and can rotate freely around its central axis. A worm gear 608 is fixedly sleeved on the outside of the hollow tube 607. The worm gear 608 has a central... Multiple positioning holes 609 are arranged in a ring at equal intervals near the edge. The lower end of the fourth explosion-proof steel pipe 6010 is fixedly sleeved inside the corresponding positioning hole 609, so that hydrogen gas enters the positioning hole 609 through the fourth explosion-proof steel pipe 6010 and then flows to the jet assembly 7. The transmission helical gear 6016 meshes with the drive bevel gear ring 404, driving the second transmission shaft 6013 to rotate. The transmission wheel 6014 at one end of the second transmission shaft 6013 is connected to the transmission wheel 6014 at one end of the first transmission shaft 6011 through the transmission belt 6015, thus transferring power. The power is transmitted to the first drive shaft 6011 via belt drive. The worm 6012 on the first drive shaft 6011 is helically engaged with the worm wheel 608. The rotation of the worm 6012 is converted into the low-speed, high-torque rotation of the hollow tube 607 through the transmission of the worm wheel 608 and the worm 6012. The transmission of the worm wheel 608 and the worm 6012 has a large reduction ratio and self-locking characteristics, which makes the hollow tube 607 rotate at a speed much lower than that of the drive shaft 201, but the output torque is greatly amplified, ensuring that the jet assembly 7 will not stop due to excessive resistance when rotating in high-viscosity adhesive.
[0039] As one implementation method in this embodiment, please refer to Figure 8 As shown, the jet assembly 7 includes an explosion-proof bend 701, which is fixedly connected to the lower air outlet of the fourth explosion-proof steel pipe 6010, and high-pressure nozzles 702 are fixedly connected to multiple air outlets at the lower part of the explosion-proof bend 701.
[0040] The explosion-proof bend 701 is fixedly connected to the lower outlet end of the fourth explosion-proof steel pipe 6010, guiding and redirecting the hydrogen from the third rotating ventilation ring 605. Multiple outlet ends of the explosion-proof bend 701 are fixedly connected to high-pressure nozzles 702. When the low-speed high-torque rotating mechanism 6 drives the hollow tube 607 to rotate, the explosion-proof bend 701 and the high-pressure nozzles 702 move in a low-speed uniform circular motion at the lower center of the nitrile rubber solution. The high-pressure nozzles 702 spray hydrogen in the form of high-pressure micro-jet. Under the superposition of the rotational motion, the hydrogen is cut and dispersed into a large number of uniform micro-bubbles. The bubbles are fully diffused into the entire rubber solution system under the dual action of high-speed rotating centrifugal force and the macroscopic flow field of the stirring blade 204, which greatly increases the gas-liquid contact area between hydrogen and nitrile rubber solution, significantly increasing the contact probability between catalyst and hydrogen, thereby significantly shortening the hydrogenation reaction time and improving the hydrogenation uniformity.
[0041] Working Principle: When this reactor is in operation, the nitrile rubber solution is first injected into the tank 105 via the feed pipe 103 controlled by the gate valve 104. After the solution fills the storage assembly 1, the gate valve 104 is closed, and the drive motor 106 starts. The drive motor 106 drives the drive shaft 201 to rotate. On one hand, the drive shaft 201 drives several stirring blades 204 on the positioning ring 203 to perform circular motion in the rubber solution, macroscopically mixing and shearing the high-viscosity nitrile rubber, preventing local deposition of the rubber solution and providing a flow field basis for hydrogen diffusion. On the other hand, the drive shaft 201 drives the drive bevel gear ring 404 to rotate synchronously via the fixed rod 401, reinforcing sleeve 402, and connecting rod 403. The outer bevel teeth of the drive bevel gear ring 404 mesh with the transmission helical gear 6016, converting the revolution into the rotation of the transmission helical gear 6016. 16 drives the second drive shaft 6013 to rotate. The drive wheel 6014 at the end of the second drive shaft 6013 drives the drive wheel 6014 on the first drive shaft 6011 to rotate via the drive belt 6015. The first drive shaft 6011 drives the worm 6012 to rotate. The worm 6012 engages helically with the worm wheel 608 fixed on the outside of the hollow tube 607. Utilizing the large reduction ratio characteristic of the worm wheel 608 and worm 6012 transmission, high speed and low torque are converted into low speed and high torque, driving the hollow tube 607 to rotate at a uniform speed near the center of the barrel 105. At the same time, hydrogen gas enters through the main inlet pipe 302. The gas enters the first rotating venting ring 301, passes through the first explosion-proof steel pipe 303, explosion-proof pipe 304, second rotating venting ring 305, and second explosion-proof steel pipe 306, and is then transferred to the third explosion-proof steel pipe 606. It is then distributed through the third rotating venting ring 605 to multiple fourth explosion-proof steel pipes 6010, and finally sprayed into the adhesive through multiple high-pressure nozzles 702 via the explosion-proof bend 701. Because the jet assembly 7 rotates synchronously at low speed with the hollow pipe 607, the hydrogen gas sprayed from the high-pressure nozzles 702 is cut into a large number of microbubbles under the action of centrifugal force and evenly projected into various areas of the adhesive. Combined with the macroscopic flow field disturbance of the stirring blades 204... The dispersion uniformity of hydrogen in high-viscosity nitrile rubber and the gas-liquid contact area are several times higher than those of traditional direct stirring methods, significantly improving catalytic reaction efficiency and greatly shortening reaction time. The uniformity of hydrogenation and batch consistency are fundamentally guaranteed. The reinforcing ring 501 and reinforcing rod 502 of the positioning component 5 ensure that the rotating mechanism remains stable and concentric during high-speed operation. The two-stage rotating venting ring of the gas transmission component 3 realizes reliable sealing and venting between the stationary pipeline and the rotating component. The entire system can achieve synchronous drive of stirring and jet rotation without additional power source. It has a compact structure, short transmission chain, and low failure rate.
