Abstract
Description
Technical Field
[0001] This utility model relates to the field of polymerization reactor technology, specifically a K30 polymerization reactor. Background Technology
[0002] K30 refers to K30 type polyacrylamide, a type of high molecular weight polymer widely used in water treatment and papermaking. Its core characteristics are low molecular weight and high cationic charge density, which can quickly adsorb sludge particles to form large flocs. In municipal sewage sludge dewatering, industrial wastewater treatment and papermaking retention processes, it can significantly improve solid-liquid separation efficiency and paper strength.
[0003] In the existing technology, the K30 polymerization reactor is a special industrial equipment designed for the production of K30 type polyacrylamide. Its core structure includes the reactor body, stirring system, feed, discharge port and temperature control components. Its main function is to adapt to the polymerization process of K30 type polyacrylamide by precisely controlling the reaction environment and the mixing state of materials, so as to ensure that the monomer is efficiently polymerized into a polymer product that meets the performance requirements.
[0004] However, K30 polymerization reactors typically employ a cooling method combining heat exchange fins and a jacket. The heat exchange fins are prone to localized heat exchange imbalances due to uneven material flow, while the jacket relies on a single cold source for cooling. Even with their combined effect, it is difficult to stably control the reactor temperature, often resulting in significant heat fluctuations. Since K30 polyacrylamide polymerization requires a specific stable temperature environment, these fluctuations can lead to uneven polymer molecular weight distribution and substandard charge density, ultimately affecting product performance. Therefore, this invention proposes a K30 polymerization reactor to address these problems. Utility Model Content

The heat exchange plates are prone to local heat exchange imbalance due to uneven material flow, while the jacket relies on a single cold source to transfer cold energy. Even with the combined effect of the two, it is still difficult to stably control the temperature inside the reactor, and obvious heat fluctuations often occur. Since K30 polyacrylamide polymerization requires a specific stable temperature environment, such fluctuations will cause uneven polymer molecular weight distribution and substandard charge density, ultimately affecting the application performance of the product.

[0014] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0015] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a K30 polymerization reactor, including a reactor body 1, which serves as the core container for the polymerization reaction. A support 4 is fixedly connected to the outer wall of the reactor body 1, and the support 4 is symmetrically distributed circumferentially around the reactor body 1 to provide stable support for the entire polymerization reactor. A feed inlet 2 is located at the top right end of the reactor body 1, facilitating the precise injection of reactants and additives. A discharge outlet 3 is located at the bottom of the reactor body 1, used for the orderly discharge of products after polymerization. A water inlet 5 is located at the top left side of the reactor body 1, and a water outlet 6 is located on the front outer wall of the reactor body 1. The water inlet 5 and the water outlet 6 pass through the interior of the reactor body 1. The heat exchange channels are connected to form a circulation path for the cooling medium. A motor mounting bracket 7 is fixedly connected to the top of the vessel body 1. The motor mounting bracket 7 is a frame structure. A stirring motor 8 is fixedly installed on the top of the motor mounting bracket 7. A connecting rod 9 is fixedly connected to the output end of the stirring motor 8. The connecting rod 9 vertically penetrates the top of the vessel body 1 and extends into the interior of the vessel body 1. A stirring blade 10 is fixedly connected to the middle of the connecting rod 9. One end of the stirring blade 10 is fixedly connected to the outer wall of the connecting rod 9. A square blade is axially arranged at the other end of the stirring blade 10. This structure can enhance the radial and axial stirring intensity of the material and ensure that the reaction system is mixed evenly. Specifically, the reaction monomers and additives required for producing K30 polyacrylamide are slowly injected into the reactor 1, which serves as the core container for the polymerization reaction, through the feed inlet 2 at the top right end of the reactor 1. The structural design of the feed inlet 2 ensures precise material injection. Then, the stirring motor 8, fixed to the top of the motor mounting bracket 7, is started. Its output drives the connecting rod 9 to rotate. The connecting rod 9 vertically penetrates the top of the reactor 1 and extends into the interior of the reactor 1. As the connecting rod 9 rotates, the stirring blades 10, fixedly connected in its middle, rotate synchronously, ensuring thorough mixing of the reaction system within the reactor 1 to meet the requirements of K30. The polymerization reaction requires uniformity of materials. During the stirring process, cooling medium is introduced into the inlet 5 on the top left side of the reactor body 1. The cooling medium flows through the heat exchange channel inside the reactor body 1 and is finally discharged from the outlet 6 on the front outer wall of the reactor body 1. The cooling medium circulation path formed by the inlet 5 and the outlet 6 can adjust the temperature inside the reactor in real time to adapt to the stable reaction environment required for K30 polymerization. Throughout the operation, the support 4, which is fixedly connected to the outer wall of the reactor body 1 and symmetrically distributed along the circumference, continues to play a role in providing stable support for the entire polymerization reactor and preventing the equipment from shaking due to stirring or medium flow. After the K30 polymerization reaction is complete, the outlet 3 at the bottom of the reactor body 1 is opened so that the generated K30 polyacrylamide product can be discharged in an orderly manner through the outlet 3, completing a single polymerization operation.
[0016] Secondly, please refer to Figure 1 and Figure 4 The top of the inlet 5 is connected to an inlet pipe 11, which serves as the channel for transporting the cooling medium. A fixing block 14 is fixedly connected to the middle of the inlet pipe 11, and one end of the fixing block 14 is fixedly connected to the outer wall of the vessel body 1. Through the rigid connection with the vessel body 1, the inlet pipe 11 is provided with stable support, preventing the pipeline from shifting due to vibration during the transport of the cooling medium. The bottom of the inlet pipe 11 is connected to a circulation pump 12, which provides the power source for the circulation of the cooling medium, ensuring that the cooling medium is transported in the system at a stable flow rate. One end of the circulation pump 12 is connected to a return water pipe 13, which is used to return the cooled medium to the outlet. After heating, the cooling medium is discharged. A fixing block 2 15 is fixedly connected to the middle of the return water pipe 13. One end of the fixing block 2 15 is fixedly connected to the outer wall of the bracket 4. With the support strength of the bracket 4, the return water pipe 13 is limited and fixed, ensuring that the pipeline layout is neat. The bottom of the return water pipe 13 is connected to the front side of the outlet 6. The bottom of the inlet 5 is connected to the cooling coil 16. The cooling coil 16 is set to fit against the inner wall of the vessel body 1, which can maximize the contact area with the material in the vessel. The bottom of the inlet 5 is connected to one end of the cooling coil 16, and the other end of the cooling coil 16 is connected to the outlet 6, forming a complete cooling medium circulation loop. Specifically, the circulation pump 12, which is connected to the bottom of the inlet pipe 11, is started. The circulation pump 12 provides power for the circulation of the cooling medium, pushing the cooling medium to be transported along the inlet pipe 11. The fixing block 14, which is fixed in the middle of the inlet pipe 11, is fixed to the outer wall of the vessel body 1 at one end. It provides stable support for the pipeline through a rigid connection, preventing the pipeline from vibrating and shifting during the transport of the cooling medium. The cooling medium flows through the inlet pipe 11 to the inlet 5 on the top left side of the vessel body 1, and then enters the cooling coil 16, which is set against the inner wall of the vessel body 1, from the bottom of the inlet 5. The cooling coil 16 maximizes the contact between the cooling medium and the material inside the vessel. The cooling medium, which has a large surface area, efficiently exchanges heat during the K30 polymerization reaction, maintaining a stable temperature inside the reactor to meet the requirements of the K30 reaction. The cooling medium that has completed the heat exchange flows from the other end of the cooling coil 16 to the outlet 6 on the front outer wall of the reactor body 1, and then enters the return water pipe 13 connected to the front of the outlet 6. The fixing block 15 fixed in the middle of the return water pipe 13 is fixed at one end to the outer wall of the support 4. The support 4 provides support strength to limit and fix the pipeline, ensuring a neat layout. Finally, the cooling medium flows back through the return water pipe 13, forming a complete circulation loop with the circulation pump 12, continuously providing a stable cooling environment for the K30 polymerization reaction until the circulation pump 12 is turned off after the reaction is completed, stopping the delivery of the cooling medium.
[0017] During operation, the reaction monomers and additives required for the production of K30 polyacrylamide are slowly injected into the reactor body 1, which serves as the core container for the polymerization reaction, through the feed inlet 2 at the top right end of the reactor body 1. The structural design of the feed inlet 2 ensures precise material injection. Subsequently, the stirring motor 8, fixed to the top of the motor mounting bracket 7, is started. Its output end drives the connecting rod 9, which runs vertically through the top of the reactor body 1 and extends into the interior, to rotate. The stirring blades 10, fixed in the middle of the connecting rod 9, rotate synchronously, ensuring that the reaction system inside the reactor is fully mixed to meet the uniformity requirements of the K30 polymerization reaction. During this process, the supports 4, symmetrically distributed around the outer wall of the reactor body 1, continuously and stably support the equipment to prevent shaking due to stirring. At the same time, the circulation pump 12, connected to the bottom of the water inlet pipe 11, is started. It provides power for the circulation of cooling medium, pushing the cooling medium to be transported along the inlet pipe 11. The fixing block 14 in the middle of the inlet pipe 11 is rigidly supported by one end connected to the outer wall of the vessel body 1, preventing the pipeline from vibrating and shifting. The cooling medium enters the cooling coil 16 that is attached to the inner wall of the vessel body 1 through the inlet 5, maximizing the heat exchange area to maintain a stable temperature inside the vessel to meet the requirements of the K30 reaction. The cooling medium that has completed heat exchange flows from the other end of the cooling coil 16 to the outlet 6, and then enters the return pipe 13. The fixing block 15 in the middle of the return pipe 13 is limited and fixed by the support 4. Finally, the cooling medium flows back through the return pipe 13 to form a circulation. After the K30 polymerization reaction is completed, the outlet 3 at the bottom of the vessel body 1 is opened to discharge the product, and at the same time the circulation pump 12 is turned off to stop cooling.
