Description

Technical Field

[0001] This utility model relates to the field of plastic additive production equipment, specifically to a reaction vessel for producing plastic additives. Background Technology

[0002] Plastic additives, also known as plastic auxiliaries, are compounds that must be added to polymers (synthetic resins) during the molding and processing process to improve their processing performance or compensate for the shortcomings of the resin itself. They play a vital role in the plastics industry, significantly enhancing the performance and usability of plastic products.

[0003] The reaction vessel used in the production of plastic additives is a key piece of equipment in the process. It is mainly used to complete various chemical reactions, such as polymerization, condensation, vulcanization, hydrocarbonation, and hydrogenation, to prepare the desired plastic additives. The reaction vessel mainly consists of a vessel body, lid, agitator, jacket, support and transmission device, and shaft sealing device. These components work together to ensure the smooth progress of the reaction process. Plastic additive production often involves materials with high viscosity and poor flowability, which traditional reaction vessels struggle to fully mix. Furthermore, plastic additives are composed of multiple components with significant differences in physical properties. Uneven mixing in the reaction vessel can cause denser components to settle at the bottom, resulting in incomplete reactions, reduced product purity, and negatively impacting the product's physical and chemical properties. Utility Model Content

[0004] To address the technical problem that existing traditional reactors are unable to uniformly stir the materials used in the production of plastic additives, resulting in incomplete reactions between materials, reduced product purity, and impact on the physical and chemical properties of the product, this utility model provides a reactor for the production of plastic additives.

[0005] The technical solution adopted by this utility model is as follows: it includes a support base, three sets of support legs are fixedly connected to the support base, a reaction vessel is placed on the support base, the lower part of the reaction vessel is set as a conical part, a platform is fixedly connected to the bottom of the conical part, an installation plate is fixedly connected to the reaction vessel, a feed pipe is fixedly installed on the reaction vessel, the feed pipe passes through the installation plate, a discharge hole is opened on the platform, a discharge pipe is fixedly connected to the bottom of the platform, a solenoid valve is fixedly installed on the discharge pipe, a rotating rod is rotatably installed on the platform, an auger blade is fixedly installed on the outside of the rotating rod, four sets of rotating shafts are rotatably installed on the installation plate, and a propeller-type stirring blade is fixedly installed at the bottom of each of the four sets of rotating shafts, and a drive mechanism is provided on the reaction vessel.

[0006] Furthermore, the drive mechanism includes a drive motor fixedly mounted on the reactor, a first gear fixedly connected to the outside of the rotating rod, and a second gear fixedly mounted on the top of the rotating shaft. The drive shaft of the drive motor is coaxially fixedly connected to the rotating rod, and the first gear meshes with the second gear.

[0007] By adopting the above technical solution, the rotation of the auger blades and the propulsion mixing blades is driven.

[0008] Furthermore, a material conveying cylinder is fixedly installed between the platform and the mounting plate. The material conveying cylinder is sleeved on the outside of the rotating rod. The bottom of the material conveying cylinder has a feed port, and the top of the material conveying cylinder has a discharge port.

[0009] By adopting the above technical solutions, the efficiency of auger blades in conveying and mixing materials can be improved.

[0010] Furthermore, an installation cavity is provided in the wall of the reactor, in which a coil is fixedly installed. An inlet pipe and an outlet pipe are fixedly installed on the outside of the reactor. One end of the coil is fixedly connected to the inlet pipe, and the other end of the coil is fixedly connected to the outlet pipe. The outlet pipe is located above the inlet pipe.

[0011] By adopting the above technical solution, the reactor can be maintained at a suitable reaction temperature.

[0012] Furthermore, a pressure relief cylinder is fixedly installed on the outside of the reactor, the pressure relief cylinder is connected to the inside of the reactor, the pressure relief cylinder has a pressure relief port, a sealing disc is slidably installed in the pressure relief cylinder, and a spring is fixedly installed between the sealing disc and the pressure relief cylinder.

[0013] By adopting the above technical solution, the internal pressure of the reactor can be kept stable.

[0014] Furthermore, a telescopic rod is fixedly connected inside the pressure relief cylinder, and the spring is sleeved on the outside of the telescopic rod.

[0015] By adopting the above technical solutions, the stability of the spring during use can be improved.

[0016] The beneficial effects of this utility model are as follows: by using a reaction vessel in conjunction with a drive motor, a conveying cylinder, a rotating rod, an auger blade, a first gear, a second gear, a rotating shaft, and a propulsion stirring blade, the auger blade conveys and stirs the bottom material upwards, while the propulsion stirring blade axially stirs the upward material discharged from the conveying cylinder and pushes it downwards. The downward material will be conveyed again by the auger blade, thus achieving the circulation and stirring of the material, avoiding the deposition of high-density material components inside the reaction vessel, allowing the materials to react fully, improving the purity of the plastic additives, and thus ensuring the physical and chemical properties of the plastic additives products.

[0017] By using the mounting cavity opened in the reactor wall, along with the inlet pipe, coil, and outlet pipe, different hot and cold liquids are circulated into the coil for heating or cooling, so that the materials in the reactor can react at a suitable temperature, thereby increasing the reaction rate and ensuring the stability and controllability of the reaction process.

[0018] By using a pressure relief cylinder, sealing plate, telescopic rod, and spring in conjunction with the reactor, when the pressure inside the reactor becomes too high during the reaction process, the internal pressure will be discharged to the outside through the pressure relief port on the pressure relief cylinder. This achieves automatic pressure relief of the reactor, eliminates the safety hazards caused by excessive internal pressure in the reactor during the production of plastic additives, and improves the practicality and safety of the reactor.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0029] To address the problems existing in the background art, this application proposes the following technical solution: A support base 1 is included, with three sets of support legs 2 fixedly connected to the bottom of the support base 1. A reaction vessel 3 is placed on the support base 1. The lower part of the reaction vessel 3 is configured as a conical section 4. A platform 5 is fixedly connected to the bottom of the conical section 4. An installation plate 6 is fixedly connected inside the reaction vessel 3. A feed pipe 7 is fixedly installed on the reaction vessel 3, penetrating the installation plate 6. A discharge hole 15 is opened on the platform 5. A discharge pipe 8 is fixedly connected to the bottom of the platform 5. A solenoid valve 9 is fixedly installed on the discharge pipe 8. A rotating rod 11 is rotatably installed on the platform 5. An auger blade 12 is fixedly installed on the outside of the rotating rod 11. Four sets of rotating shafts 17 are rotatably installed on the installation plate 6. Each of the four sets of rotating shafts 17 has a propeller-type stirring blade 18 fixedly installed at its bottom. A drive mechanism is provided on the reaction vessel.

[0030] The materials required for the production of plastic additives are added into the reactor 3 through the feed pipe 7. The drive mechanism drives the rotating rod 11 and the rotating shaft 17 to rotate. The rotating rod 11 drives the auger blade 12 to rotate. The auger blade 12 conveys the material in the middle of the bottom of the reactor 3 upward and stirs the material. The rotating shaft 17 drives the propeller-type stirring blade 18 to rotate. The propeller-type stirring blade 18 stirs the material axially and pushes the material downward. The downward material returns to the bottom of the auger blade 12 through the conical part 4 and is conveyed upward again, thus realizing the circulation and stirring of the material. This avoids the deposition of high-density material components at the bottom of the reactor 3, ensures the full reaction between the materials, improves the purity of the product, and thus ensures the physical and chemical properties of the plastic additive product. After the material has fully reacted, the solenoid valve 9 is opened, and the plastic additive product is discharged from the inside of the reactor 3 through the discharge hole 15 and the discharge pipe 8.

[0031] To further explain, the drive mechanism includes a drive motor 27 fixedly mounted on the reactor 3, a first gear 16 fixedly connected to the outside of the rotating rod 11, and a second gear 28 fixedly mounted on the top of the rotating shaft 17. The drive shaft of the drive motor 27 is coaxially fixedly connected to the rotating rod 11, and the first gear 16 meshes with the second gear 28.

[0032] The drive motor 27 drives the rotating rod 11 to rotate, the rotating rod 11 drives the auger blade 12 to rotate, the rotating rod 11 simultaneously drives the first gear 16 to rotate, the first gear 16 drives the second gear 28 to rotate, and the second gear 28 drives the propeller-type stirring blade 18 to rotate. Through the drive mechanism, a set of drive motors 27 simultaneously drives the auger blade 12 and the propeller-type stirring blade 18 to rotate, so that the material inside the reactor 3 is stirred evenly, while reducing the manufacturing cost of the reactor 3 and improving the practicality of the reactor 3.

[0033] Furthermore, a material conveying cylinder 10 is fixedly installed between the platform 5 and the mounting plate 6. The material conveying cylinder 10 is sleeved on the outside of the rotating rod 11. The bottom of the material conveying cylinder 10 has a feed inlet 13, and the top of the material conveying cylinder 10 has a discharge outlet 14.

[0034] During the material mixing process, the material at the bottom of the reactor 3 enters the interior of the conveying cylinder 10 through the feed inlet 13. The auger blade 12 rotates to convey and mix the material inside the conveying cylinder 10 upwards. After the material rises to the top of the conveying cylinder 10, it is discharged into the interior of the reactor 3 through the discharge outlet 14. The propeller-type stirring blade 18 rotates to mix and push the material downwards, realizing the circulation and mixing of the material. The conveying cylinder 10 restricts the material inside, improving the conveying and mixing effect of the auger blade 12, thereby ensuring the uniform mixing effect of the material in the reactor 3.

[0035] Furthermore, the reactor 3 has an installation cavity 29 in its wall, in which a coil 19 is fixedly installed. An inlet pipe 20 and an outlet pipe 21 are fixedly installed on the outside of the reactor 3. One end of the coil 19 is fixedly connected to the inlet pipe 20, and the other end of the coil 19 is fixedly connected to the outlet pipe 21. The outlet pipe 21 is located above the inlet pipe 20.

[0036] The inlet pipe 20 is connected to an external liquid supply device (not shown in the attached drawing), and the outlet pipe 21 is connected to an external liquid collection device (not shown in the attached drawing). The liquid supply device delivers hot liquid to the inlet pipe 20. The hot liquid flowing in the coil 19 can increase the internal temperature of the reactor 3. The inlet pipe 20 delivers cold liquid. The cold liquid flowing in the coil 19 can decrease the internal temperature of the reactor 3. By circulating different hot and cold liquids into the coil 19 for heating or cooling, the materials in the reactor 3 can react at a suitable temperature, ensuring the stability and controllability of the reaction process, thereby improving the practicality of the reactor 3.

[0037] Furthermore, a pressure relief cylinder 22 is fixedly installed on the outside of the reactor 3. The pressure relief cylinder 22 is connected to the inside of the reactor 3. A pressure relief port 23 is opened on the pressure relief cylinder 22. A sealing disc 24 is slidably installed in the pressure relief cylinder. A spring 25 is fixedly installed between the sealing disc 24 and the pressure relief cylinder 22.

[0038] As the materials inside reactor 3 react, the pressure inside reactor 3 gradually increases. The increased pressure pushes the sealing disc 24 towards the pressure relief port 23. When the sealing disc 24 moves, the spring 25 is compressed and deformed. When the sealing disc 24 moves to the pressure relief port 23, the excessive pressure inside reactor 3 is discharged to the outside through the pressure relief port 23, thereby reducing the pressure inside reactor 3. After the pressure decreases, the compressed spring 25 pushes the sealing disc 24 to move away from the pressure relief port 23 in order to return to its initial state. The pressure relief port 23 no longer discharges pressure from reactor 3, thus realizing automatic pressure relief of reactor 3. At the same time, the structure is simple and eliminates the safety hazards caused by excessive internal pressure of reactor 3 during the production of plastic additives, thereby improving the practicality and safety of reactor 3.

[0039] Furthermore, a telescopic rod 26 is fixedly connected inside the pressure relief cylinder 22, and a spring 25 is sleeved on the outside of the telescopic rod 26.

[0040] The telescopic rod 26 guides and limits the spring 25, preventing the spring 25 from shifting during deformation, ensuring the spring 25 can work normally, and improving the stability of the pressure relief cylinder 22 during use.

[0041] The specific operation is as follows: The materials required for the production of plastic additives are added into the reactor 3 through the feed pipe 7. The drive motor 27 drives the rotating rod 11 to rotate, and the rotating rod 11 drives the auger blade 12 to rotate. The material at the bottom of the reactor 3 enters the conveying cylinder 10 through the feed port 13. The rotating auger blade 12 conveys and stirs the material inside the conveying cylinder 10 upwards. After the material rises to the top of the conveying cylinder 10, it is discharged into the reactor 3 through the discharge port 14. At the same time, the rotating rod 11 drives the first gear 16 to rotate, and the first gear 16 drives the second gear 28 to rotate. The second gear 28 drives... The rotating propeller-type agitator 18 agitates the material axially and pushes it downwards. The descending material returns to the platform 5 after passing through the cone section 4 and enters the conveying cylinder 10 again through the feed inlet 13, thus circulating and agitating the material. The liquid inlet pipe 20 is connected to the external liquid supply equipment, and the liquid outlet pipe 21 is connected to the external liquid collection equipment. Different hot and cold liquids are circulated into the coil 19 through the liquid inlet pipe 20 for heating or cooling, so that the material in the reactor 3 can react at a suitable temperature, ensuring the stability and controllability of the reaction process.
