Abstract
Description
Technical Field
[0001] This application relates to the technical field of industrial equipment, and in particular to an apparatus for preparing carboxylated butadiene nitrile latex that prevents adhesion. Background Technology
[0002] Carboxylated nitrile butadiene latex is a special rubber latex copolymerized from butadiene, acrylonitrile, and carboxylic acid monomers. It possesses excellent oil resistance, abrasion resistance, and adhesion, and is widely used in seals, hoses, coatings, and other fields. However, during its preparation process (such as emulsion polymerization, stirring, and filtration), the latex, due to its high viscosity and chemical activity, easily adheres to the inner surfaces of equipment such as reaction vessels, pipes, and stirring devices, forming stubborn residues.
[0003] A search revealed Chinese patent publication number CN217568629U, which discloses a polymerization reactor, including a reactor body. The reactor body has a spare inlet at its top, connected to a steam branch pipe. The steam branch pipe is connected to a steam source and has a first valve connected to a DCS control system. The reactor body has a discharge pipe at its bottom, with a blocking valve located directly above the inlet of the discharge pipe. The diameter of the blocking valve is not less than the diameter of the inlet of the discharge pipe. The blocking valve is located inside the reactor body. A feed inlet is located between the blocking valve and the discharge pipe. The discharge pipe has a second valve connected to the DCS control system. This invention saves costs, reduces reactor cleaning costs, reduces material residue, and avoids the problem of high-pressure steam breaking down the material, leading to leakage and loss of extrusion pressure. It is suitable for polymerization reactors.
[0004] The aforementioned patent specification mentions that "the spare reactor port is connected to a steam branch pipe, which is connected to a steam source. The steam source is the main steam pipeline of the plant area, making full use of the steam generated in the plant area and saving costs; the steam branch pipe is equipped with a first valve, which is connected to the DCS control system; the bottom of the polymerization reactor body is equipped with a discharge pipe, and a blocking valve is located directly above the inlet end of the discharge pipe. The diameter of the blocking valve is not less than the diameter of the inlet end of the discharge pipe. The blocking valve is located inside the polymerization reactor body, and a feed inlet is located between the blocking valve and the discharge pipe. The discharge pipe is equipped with a second valve, which is connected to the DCS control system." However, some of these aspects cannot be changed to reduce the internal thickness. In response to the aforementioned related technologies, an anti-adhesion carboxylated nitrile latex preparation device is proposed to solve the above problems. Utility Model Content

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.
[0031] Example: Apparatus for preparing anti-adhesion carboxylated nitrile latex, refer to Figures 1 to 3 The system includes a supporting shell 1, a cleaning mechanism 2 fixedly connected to the outside of the supporting shell 1, and a multi-layer mechanism 3 fixedly connected to the outside of the supporting shell 1. The cleaning mechanism 2 includes a driving assembly 21 for driving, which is the power core of the cleaning mechanism 2. It consists of a rotating motor 211 and a connecting rotating column 212. A connecting rotating rod 22 is fixedly connected to the outside of the driving assembly 21. A connecting rotating ring 23 is fixedly connected to the outside of the connecting rotating rod 22. A connecting rotating rod 24 is rotatably connected to the outside of the connecting rotating ring 23. One end of the connecting rotating rod 22 is fixedly connected to the outside of the driving assembly 21, and the other end is rotatably connected to the inside of the supporting shell 1, so as to transmit the rotation of the driving assembly 21 to the connecting rotating ring 23.
[0032] A limiting block 25 is rotatably connected to the outer end of the connecting rotating rod 24, i.e., the end away from the connecting rotating ring 23. A supporting slide rail 28 is fixedly connected to the outer side of the limiting block 25. The limiting block 25 is fixedly connected to the connecting rotating rod 24 to restrict the movement of the connecting rotating rod 24 and prevent it from excessively deviating or shaking during the movement, thus ensuring the stability of the entire transmission structure. The outer side of the supporting slide rail 28 is slidably connected to the outer side of the drive assembly 21. A connecting sliding column 26 is fixedly connected to the drive end of the drive assembly 21. A connecting cleaning brush 27 is fixedly connected to the bottom of the connecting sliding column 26. The top of the connecting sliding column 26 is fixedly connected to the outer side of the connecting rotating column 212, and the bottom is fixedly connected to the connecting cleaning brush 27. The entire cleaning mechanism 2 plays the role of connecting and transmitting motion.
[0033] The drive assembly 21 includes a rotary motor 211, the drive end of the rotary motor 211 is fixedly connected to a connecting rotary column 212, the outside of the rotary motor 211 is slidably connected to the outside of the support slide rail 28, the outside of the connecting rotary column 212 is slidably connected to the outside of the support slide rail 28, the outside of the connecting rotary column 212 is fixedly connected to the outside of the connecting sliding column 26, and the outside of the connecting cleaning brush 27 is slidably connected to the bottom of the inner side of the support housing 1.
[0034] The external sliding column 26 is slidably connected to the inner side of the supporting shell 1, the external fixed connection of the supporting slide rail 28 is fixedly connected to the inner side of the supporting shell 1, the external rotating rod 24 is rotatably connected to the inner side of the supporting shell 1, the external rotating rod 22 is rotatably connected to the inner side of the supporting shell 1, and the external rotating ring 23 is rotatably connected to the inner side of the supporting shell 1.
[0035] Specifically, the rotating motor 211, as the core of the drive component 21, drives the connecting rotating column 212 to rotate. Through the connecting rotating rod 1 22, the connecting rotating ring 23, and the connecting rotating rod 24, the limiting block 25 and the supporting slide rail 28 ensure stable movement. The transmission causes the rotating motor 211 to slide along the supporting slide rail 28, driving the connecting sliding column 26 and the connecting cleaning brush 27 to clean the bottom inside the supporting shell 1. This reduces the frequency and intensity of cleaning, and continuous and efficient cleaning can prevent latex residue from deteriorating and affecting product quality, ensure the continuity of the preparation process, improve production efficiency, reduce equipment maintenance costs, and extend the service life of the device.
[0036] Reference Figure 1 and Figure 4 The multi-layer structure 3 includes a waterproof layer 31, which is fixedly connected to the inner side of the supporting shell 1. Its main function is to prevent external moisture from penetrating into the supporting shell 1 and to avoid moisture interfering with the preparation process of carboxylated nitrile latex. A protective outer layer 32 is fixedly connected to the outside of the waterproof layer 31. The protective outer layer 32 is located outside the waterproof layer 31 and mainly plays a physical protection role. A support layer 33 is fixedly connected to the outside of the protective outer layer 32. The support layer 33 plays a key role in support and stability in the multi-layer structure 3. A high-temperature resistant layer 34 is fixedly connected to the outside of the support layer 33. In the preparation process of carboxylated nitrile latex, it is often necessary to react under certain temperature conditions, which may generate high temperatures or require heating treatment of the reaction system. A corrosion-resistant layer 35 is fixedly connected to the outside of the high-temperature resistant layer 34. Various chemical reagents may be used in the preparation process of carboxylated nitrile latex. These chemical reagents are highly corrosive and can easily cause corrosion damage to the inner wall of the device. The waterproof layer 31 is fixedly connected to the inside of the supporting shell 1. A connecting support column 4 is fixedly connected to the bottom of the supporting shell 1.
[0037] Specifically, the waterproof layer 31 is tightly attached to the inside of the supporting shell 1, isolating external moisture and maintaining a dry latex preparation environment; the protective outer layer 32 resists collisions and friction, protecting the internal structure; the supporting layer 33 provides stable mechanical support with high-strength materials; the high-temperature resistant layer 34 withstands the high temperature of the reaction, reducing heat loss and shell deformation; and the corrosion-resistant layer 35 resists reagent corrosion with its chemical stability. The synergistic effect of these layers can prevent moisture and impurities from interfering with the reaction, ensuring the purity and performance stability of the latex, reducing the risk of equipment damage due to external forces, high temperatures, and corrosion, reducing the frequency of maintenance and replacement, extending the life of the equipment, stabilizing the reaction environment, improving production efficiency, ensuring product quality, and reducing overall operating costs.
[0038] The implementation principle of this application embodiment is as follows: the operation of the rotating motor 211 drives the operation of the connecting rotating column 212, thereby driving the rotation of the connecting rotating rod 22, which in turn drives the rotation of the connecting rotating ring 23 and the connecting rotating rod 24. At the same time, the limiting block 25 provides support for the rotation of the connecting rotating rod 24, ensuring the normal rotation of the connecting rotating rod 24. This drives the rotating motor 211 to slide, thereby driving the sliding column 26 and the cleaning brush 27 to slide, thus achieving the effect of cleaning the bottom. Meanwhile, the supporting slide rail 28 provides support for the sliding of the rotating motor 211. At the same time, the ultrasonic anti-adhesion module is activated. When working together with the ultrasonic module, it can further reduce the thickness of the residual adhesive film. In addition, an internal circulating temperature control system is set to ensure heat transfer efficiency.
[0039] The waterproof layer 31 is attached to the inside of the supporting shell 1 to maintain a dry environment for latex preparation. The protective outer layer 32 resists mechanical damage such as external collisions and friction, and protects the internal structure. The supporting layer 33 is made of high-strength material to provide mechanical support for the multi-layer structure and ensure overall stability. The high-temperature resistant layer 34 withstands the high temperature of the reaction, prevents the shell from deforming and reduces heat loss. The corrosion-resistant layer 35 is located in the innermost layer and resists reagent corrosion with chemically stable materials. The synergistic effect of each layer ensures the stable operation of the carboxylated nitrile latex preparation device and improves the service life of the device and the quality of latex preparation.
