Description

Technical Field

[0001] This invention belongs to the field of coupling agent preparation technology, and relates to a coupling agent preparation production line and process. Background Technology

[0002] Coupling agents, as an important chemical additive, are widely used in many fields such as plastics, rubber, coatings, and adhesives. They can improve the interfacial bonding performance between different materials, enhance the mechanical properties, heat resistance, and weather resistance of composite materials, and play a key role in improving product quality and performance. With the rapid development of related industries, the demand for coupling agents is constantly increasing, which also puts forward higher requirements for their production efficiency and product quality.

[0003] The existing production process of coupling agents typically involves multiple steps, including material storage, reaction, mixing, and granulation. Currently, although some coupling agent preparation production lines are in operation, these lines still have many shortcomings in actual operation.

[0004] In the material mixing stage, the existing mixers have limited mixing effect, making it difficult to ensure that the materials are fully and evenly mixed. The internal structure design of the mixer is unreasonable, and the mixing method and angle of the mixing spoon are limited, which makes it impossible to effectively shear, disperse and mix the materials. This results in unstable quality of the mixed materials, which in turn affects the performance of the coupling agent products. In addition, the discharge process of the mixer is also cumbersome, and the design of the discharge port is not reasonable, which easily leads to material residue and blockage, affecting production efficiency.

[0005] Sampling is an indispensable part of the coupling agent production process. Through sampling and testing, the mixing status of materials and product quality can be understood in a timely manner. However, existing sampling methods have many drawbacks. The sampling device is usually fixed in a certain position of the mixer, and the sampling position cannot be flexibly adjusted according to actual needs. It is difficult to obtain representative samples. Moreover, materials are prone to leakage during the sampling process, which not only wastes materials but may also pollute the production environment. After sampling, the residual materials in the sampling device are difficult to clean, which can easily breed bacteria and impurities, affecting the accuracy of subsequent sampling.

[0006] Therefore, we propose a coupling agent preparation production line and process to solve the problems mentioned above. Summary of the Invention

[0007] In view of this, the present invention addresses the problems that sampling devices are usually fixed in a certain position in the mixer, making it impossible to flexibly adjust the sampling position according to actual needs, making it difficult to obtain representative samples, and that material leakage is easy during the sampling process, which not only causes material waste but may also pollute the production environment. After sampling, the residual material in the sampling device is difficult to clean, which can easily breed bacteria and impurities, affecting the accuracy of subsequent sampling. The present invention provides a coupling agent preparation production line and process.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a coupling agent preparation production line, including a mixer for mixing materials;

[0009] The mixer includes a cylinder, and a sampling mechanism is provided on the cylinder;

[0010] The sampling mechanism includes a fixed cylinder that penetrates the outer wall of the cylinder, a sampling rod inserted into the fixed cylinder, a sampling groove being provided at the top of the sampling rod, and a blocking plate being provided at one end of the fixed cylinder for use with the sampling rod.

[0011] It also includes a vibration assembly mounted on a fixed cylinder;

[0012] During sampling, the sampling rod is inserted into the fixed cylinder and contacts the blocking plate away from the fixed cylinder, and the material enters the sampling tank.

[0013] After sampling, the sampling rod is pulled out, the plug plate resets and seals the fixed cylinder port, and the vibration component generates vibration to clean the material from the plug plate and the fixed cylinder port.

[0014] As a further improvement to the above technical solution:

[0015] The outer wall of the cylinder has a rectangular hole, and a slider is slidably arranged in the rectangular hole. The fixed cylinder is fixedly arranged inside the slider. Sealing plates are welded to the top and bottom of the slider, and a limiting component is provided on one side of the slider.

[0016] The limiting assembly includes a cam that is rotatably sleeved on the outer wall of the fixed cylinder via a bearing. A plug rod that slidably contacts the cam is disposed on one side of the slider. A second spring is sleeved on the outer wall of the plug rod, and the two ends of the second spring respectively contact one side of the slider and one end of the outer wall of the plug rod. At least three fixing blocks are fixedly disposed on the outer wall of the cylinder, and a plug hole that matches the plug rod is opened on one side of the fixing block.

[0017] The outer wall of the cam has a flat portion, which is used to limit the position of the insert rod and the cam.

[0018] The fixed cylinder has multiple mounting holes at one end, and a sliding rod is slidably installed in each mounting hole. A first spring is installed in each mounting hole, and the two ends of the first spring contact one side of the inner wall of the mounting hole and one end of the sliding rod, respectively. The blocking plate is welded to one end of the multiple sliding rods.

[0019] Both the fixed cylinder and the blocking plate have a tapered section on their adjacent sides. The tapered section has a groove, and a rubber ring is placed in the groove. The rubber ring is used to cover the end and to clean the surface material when the tapered sections move relative to each other.

[0020] The vibration assembly includes an extension strip welded to one side of a fixed block, and a striking block is rotatably arranged inside the extension strip via a rotating shaft. A torsion spring is sleeved on the outer wall of the rotating shaft, and the two ends of the torsion spring contact the inner wall of the extension strip and the top of the striking block, respectively.

[0021] The outer wall of the sampling rod is provided with multiple slots, and a limiting block is fixedly provided on one side of the cam;

[0022] When the sampling rod moves, it drives the striking block to strike the limiting block, generating vibration.

[0023] Multiple baffles are fixedly installed on the inner wall of the cylinder.

[0024] It also includes a second motor, the output end of which extends into the cylinder and is fixedly fitted with a connecting seat, and multiple inclined second stirring spoons are connected inside the connecting seat.

[0025] A coupling agent preparation process, using the above-mentioned coupling agent preparation production line, includes the following steps:

[0026] S1. Add polysulfide silane and polyether oligomer to the reactor, heat to 80±5℃ and stir to premix, heat to 110±2℃ and react for 2 hours, cool down and transfer to the storage tank for heat preservation.

[0027] S2. Add the materials and carbon black to the mixer, mix at low speed first and then at high speed;

[0028] S3. During the mixing process, sampling is performed by a sampling mechanism: the sliding slider is adjusted to adjust the position, the sampling rod is inserted to allow the material to enter the sampling slot, and the vibration component cleans up the residual material when the sampling rod is pulled out.

[0029] S4. After the sample is qualified, it is granulated by a granulator. The barrel temperature is controlled in stages and cooled.

[0030] The beneficial effects of this invention are as follows:

[0031] 1. The coupling agent preparation production line disclosed in this invention has a sampling mechanism installed through the outer wall of the cylinder. Material samples inside the cylinder can be easily obtained through the sampling groove of the sampling rod. A blocking plate at one end of the fixed cylinder seals the port after sampling, preventing material leakage and the entry of external impurities, thus ensuring sampling accuracy. Furthermore, the vibration component generates vibration during sampling, which can clean the blocking plate and the port of the fixed cylinder, preventing material residue from affecting subsequent sampling results. It also facilitates the insertion and removal of the sampling rod.

[0032] 2. The coupling agent preparation production line disclosed in this invention allows the fixed cylinder to slide on the cylinder body by opening a rectangular hole on the outer wall of the cylinder and setting a slider, thereby realizing flexible adjustment of the sampling position. The design of the limiting component can ensure that the fixed cylinder is firmly fixed after being adjusted to the appropriate position, ensuring the stability and reliability of sampling. It can meet the sampling needs of different production stages and different material positions, and provides strong support for production process monitoring and quality inspection.

[0033] 3. The coupling agent preparation production line disclosed in this invention has a cam, a plug rod, and a second spring in the limiting component that cooperate with each other. By rotating the cam and inserting the plug rod, the position of the fixed cylinder is precisely fixed. The flat part opened on the outer wall of the cam can cooperate with the plug rod to further enhance the limiting effect, prevent the fixed cylinder from shifting during the production process, and ensure the normal operation of the sampling mechanism.

[0034] 4. The coupling agent preparation production line disclosed in this invention has a plug plate connected to a fixed cylinder via a sliding rod, and the plug plate is tightly fitted to the port of the fixed cylinder by the elastic force of the first spring, ensuring good sealing performance. At the same time, the conical part and rubber ring set on the side close to each other between the fixed cylinder and the plug plate can not only further prevent material from sticking to the end, but also clean the material on the surface of the conical part under the action of the vibration component, thereby improving the service life and cleanliness of the equipment.

[0035] 5. The coupling agent preparation production line disclosed in this invention has a striking block in the vibration component that engages with the slot of the sampling rod under the action of a torsion spring. During the movement of the sampling rod, the sampling rod is automatically struck, generating a vibration effect. At the same time, a limiting block set on one side of the cam engages with the striking block, further enhancing the striking force and frequency, improving the cleaning effect on the blockage plate and the material at the fixed cylinder port, and ensuring the normal operation of the sampling mechanism and the accuracy of the sampling results.

[0050] Example 1

[0051] like Figures 1-8 As shown, a coupling agent preparation production line includes a reaction vessel 1, a first storage tank 2, a second storage tank 3, a mixer 6, and a granulator 5. The reaction vessel 1 is used for the chemical reaction of materials. The first and second storage tanks 2 and 3 are used to store different materials and provide insulation. The mixer 6 is used to thoroughly mix the materials, and the granulator 5 granulates the mixed materials. The reaction vessel is made of 316L stainless steel, with an inner wall polished to Ra0.4μm, a volume of 2000L, and equipped with a jacketed heating / cooling system. The temperature control range is -10℃ to 200℃, with an accuracy of ±1℃. The first and second storage tanks 2 and 3 are symmetrically arranged, both using a φ1200mm×1800mm cylindrical structure. The granulator is an SWP-400 type plastic extrusion granulator.

[0052] Both the first storage tank 2 and the second storage tank 3 are equipped with welded supports 4 at their bottoms. The supports 4 are made of carbon steel with a welding height of 800mm, and their surfaces are coated with epoxy zinc-rich primer for corrosion protection, ensuring the stable placement of the storage tanks. A ladder 7 is provided on one side of each tank. The ladder 7 is made of carbon steel with a width of 600mm and a step spacing of 300mm, conforming to GB4053.1 standard. This facilitates access for operators to add materials or perform equipment maintenance.

[0053] The mixer 6 mainly includes a cylinder 61, a first support frame 62, a first motor 63, a rotating shaft 631, a first stirring spoon 632, a discharge assembly, a sampling mechanism 8, and a vibration assembly.

[0054] The cylinder 61 is the main working chamber of the mixer 6, and its top is connected to the first motor 63 via the first support frame 62. The output end of the first motor 63 is connected to the rotating shaft 631 by bolts, and the outer wall of the rotating shaft 631 is fixedly fitted with a first stirring spoon 632. When the first motor 63 is started, the rotating shaft 631 drives the first stirring spoon 632 to rotate, which fully stirs the material in the cylinder 61. The first stirring spoon 632 is used for mixing (low speed, paddle type).

[0055] A discharge chute 64 is fixedly provided at the bottom of the cylinder 61, with an inclination angle of 45°, and the discharge chute 64 is connected to the interior of the cylinder 61. A discharge port 613 is opened at the bottom of the cylinder 61, and a cover plate 65 is inserted inside the port. When discharge is required, simply pull out the cover plate 65, and the material can be discharged through the discharge port 613 and the discharge chute 64. The discharge chute 64 corresponds to the feed port of the granulator 5, and can directly discharge into the granulator 5 without further conveying.

[0056] To monitor the quality of materials during the mixing process in real time, the mixer 6 is also equipped with a sampling mechanism 8. The sampling mechanism 8 includes a fixed cylinder 82 that runs through the outer wall of the cylinder body 61, and a sampling rod 83 is inserted into the fixed cylinder 82. A sampling groove 86 is opened at the top of the sampling rod 83. The sampling groove 86 has a volume of 5-10 mL, accounting for 0.1%-0.2% of the total volume of the mixer, and the inner wall of the groove is coated with polytetrafluoroethylene for collecting material samples.

[0057] One end of the fixed cylinder 82 is equipped with a blocking plate 85 that cooperates with the sampling rod 83. Multiple mounting holes 821 are formed at one end of the fixed cylinder 82. A sliding rod 84 slides within each mounting hole 821, and a first spring 822 with an elastic coefficient of 5-10 N / mm is installed within each mounting hole 821. The two ends of the first spring 822 abut against one side of the inner wall of the mounting hole 821 and one end of the sliding rod 84, respectively. The blocking plate 85 is welded to one end of the sliding rods 84. Before sampling, the blocking plate 85 seals one end of the fixed cylinder 82 to prevent material leakage. During sampling, the sampling rod 83 is inserted into the fixed cylinder 82, moving away from the fixed cylinder 82 and contacting the blocking plate 85, allowing the material to enter the sampling groove 86. After sampling, the sampling rod 83 is pulled out, and the blocking plate 85 automatically resets under the action of the first spring 822, resealing one end of the fixed cylinder 82.

[0058] To ensure stable insertion and removal of the sampling rod 83, a fixed cylinder 82 is fixedly installed inside the slider 81. The slider 81 is slidably disposed within a rectangular hole 612 opened in the outer wall of the cylinder 61. Sealing plates 87 are welded to its top and bottom, and an elastic sealing ring is provided at the gap between the sealing plate 87 and the rectangular hole 612 for dynamic sealing of the rectangular hole 612. A limiting component is provided on one side of the slider 81 to fix the position of the fixed cylinder 82.

[0059] The limiting assembly includes a cam 14 rotatably mounted on the outer wall of the fixed cylinder 82 via a bearing, and a sliding rod 12 that abuts against the cam 14 is slidably mounted on one side of the slider 81. A second spring 13 is mounted on the outer wall of the sliding rod 12, and the two ends of the second spring 13 abut against one side of the slider 81 and one end of the outer wall of the sliding rod 12, respectively, via connecting seats. At least three fixing blocks 67 are fixedly mounted on the outer wall of the cylinder 61, and one side of each fixing block 67 has a hole adapted to the sliding rod 12. The head of the sliding rod 12 has a conical, spherical, or wedge-shaped guide structure.

[0060] When the position of the fixed cylinder 82 needs to be adjusted, simply rotate the cam 14 so that the flat part 16 of the cam 14 abuts against the insert rod 12. At this time, the insert rod 12 can be inserted into the insertion hole on one side of the fixed block 67 under the action of the cam 14, thus fixing the fixed cylinder 82. When the fixed cylinder 82 needs to be moved, rotate the cam 14 again so that the curved part of the cam 14 contacts the insert rod 12. At this time, the insert rod 12 is pulled out from the insertion hole under the action of the second spring 13, and the fixed cylinder 82 can be moved.

[0061] To generate vibration during sampling and clean the material at the ports of the blocking plate 85 and the fixed cylinder 82, the mixer 6 is also equipped with a vibration assembly. The vibration assembly includes an extension strip 671 welded to one side of the fixed block 67, and a striking block 672 rotatably mounted inside the extension strip 671 via a rotating shaft 673. A torsion spring 674 is fitted onto the outer wall of the rotating shaft 673, with its two ends contacting the inner wall of the extension strip 671 and the top of the striking block 672, respectively. The torque of the torsion spring 674 is 0.5-1.2 N·m.

[0062] The outer wall of the sampling rod 83 has multiple slots 17 that cooperate with the striking block 672. When the sampling rod 83 moves, the striking block 672 continuously strikes the slots 17 of the sampling rod 83 under the action of the torsion spring 674, generating vibration.

[0063] Example 2

[0064] Reference Figures 1-8 This invention provides a novel technical solution: a coupling agent preparation production line. A conical portion 9 is provided on the side of the fixed cylinder 82 and the blocking plate 85 that are close to each other. A groove 10 is formed on the conical portion 9, and a rubber ring 11 is provided within the groove 10. The rubber ring 11 is made of fluororubber (FKM) (chemically resistant, withstanding temperatures from -20℃ to 200℃). When the fixed cylinder 82 and the blocking plate 85 are close to each other, the two rubber rings 11 can abut against each other and move. During this movement, the rubber ring 11 can expand using the conical portion 9, thereby expanding and moving, and cleaning the outer surface of the conical portion 9. Conversely, when the fixed cylinder 82 and the blocking plate 85 are far apart, the rubber ring 11 can contract under elastic force and move on the conical portion 9 until it moves into the groove 10 and stops moving. At this time, the end of the rubber ring 11 protrudes from the ends of the fixed cylinder 82 and the blocking plate 85, reducing the amount of material falling into the ports of the fixed cylinder 82 and the blocking plate 85.

[0065] Meanwhile, a limiting block 15 is fixed on one side of the cam 14 to cooperate with the striking block 672. When the sampling rod 83 moves to a certain position, the striking block 672 contacts the limiting block 15, generating greater vibration and thoroughly cleaning the material at the port of the blocking plate 85 and the fixed cylinder 82.

[0066] To further improve the mixing effect, the mixer 6 also includes a second stirring spoon 682 inside the cylinder 61. A second motor 68 is bolted to the second support frame 66, and the output end of the second motor 68 extends into the cylinder 61 and is fixedly fitted with a connecting seat 681. Multiple inclined second stirring spoons 682 are bolted into the connecting seat 681, with an inclination angle of 40°±5°, for dispersion (high speed, 45° inclined anchor type).

[0067] When the second motor 68 starts, the second stirring spoon 682 rotates under the drive of the second motor 68, performing secondary stirring of the material inside the cylinder 61. Because the second stirring spoon 682 is tilted, its stirring effect is more significant, ensuring that the material is fully mixed.

[0068] Add polysulfide silane and polyether oligomer to enamel reactor 1 at a mass ratio of 2:1 using a material pump. Turn on the stirring device (anchor-type stirring paddle, speed 60-80 rpm) and simultaneously heat the material to 80±5℃ using electric heating. Keep the material warm and stir for 30 minutes to ensure thorough premixing.

[0069] 0.4 MPa of saturated steam is introduced into the jacket of reactor 1, and the material is heated to 110 ± 2 °C at a heating rate of 2 °C / min.

[0070] Maintain the temperature and adjust the stirring speed to 120 rpm (propeller-type stirrer), and react for 2 hours.

[0071] After the reaction is complete, the material is cooled to below 60°C and transferred to a storage tank.

[0072] The storage tank is insulated with circulating water to maintain the material temperature at 50±2℃, and the storage time is ≤24 hours.

[0073] The insulated liquid material and carbon black are added to mixer 6 at a mass ratio of 1:1 for mixing.

[0074] First, mix at a low speed (40 rpm, 5 minutes) to impregnate the material with carbon black, then switch to high speed mixing (120 rpm, 10 minutes). During mixing, first start the second motor 68 to drive the second stirring spoon 682 to rotate, and finally start the first motor 63 to drive the first stirring spoon 632 to rotate.

[0075] During the mixing process, sampling is performed, and the slider 81 is pushed to move downward on the first support frame 62 until it reaches the lowest end. The cam 14 is rotated, and during the rotation of the cam 14, the insertion rod 12 can be driven to move outward and compress the second spring 13 until the insertion rod 12 is inserted into the insertion hole on one side of the fixing block 67. At this time, the position of the slider 81 can be fixed.

[0076] When the sampling rod 83 is inserted into the fixed cylinder 82, it can move outward against the blocking plate 85. During the outward movement of the blocking plate 85, the rubber ring 11 can contract under the elastic force and slide on the conical part 9, and can automatically move into the groove 10. At the same time, it drives the sliding rod 84 to move in the mounting hole 821 and stretches the first spring 822. Moreover, the striking block 672 can be inserted into the corresponding slot 17 under the force of the torsion spring 674 until the blocking plate 85 moves into place. At this time, the mixed material inside the cylinder 61 can fall into the sampling groove 86 until the sampling groove 86 is completely collected.

[0077] Pulling the sampling rod 83 outward can drive the striking block 672 to rotate using the slot 17 and compress the torsion spring 674. When the slot 17 moves away from the striking block 672, the striking block 672 can reset and rotate under the force of the torsion spring 674 and get stuck in the corresponding slot 17. During the reset and rotation, it can strike the limiting block 15, causing the sampling rod 83 to vibrate, which can shake off the material at the end of the fixed cylinder 82 and the end of the blocking plate 85. The blocking plate 85 can reset and move under the force of the first spring 822. When the two rubber rings 11 of the blocking plate 85 are released, they can push each other through mutual force, causing the rubber rings 11 to move on the conical part 9, which can further clean the material on the conical part 9 until the sampling rod 83 is separated from the fixed cylinder 82 and the material at the bottom is taken out.

[0078] The above method was used to sample the material in the middle and upper parts in sequence.

[0079] After the sample passes the test, it is directly granulated by granulator 5. The barrel temperature is controlled in stages: 30℃ in the feeding section, 60℃ in the compression section, and 80℃ in the die section. The granules are then cooled to room temperature.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
