Description

Technical Field

[0001] This utility model relates to the field of nitrile latex production technology, specifically to a continuous polymerization production device for nitrile latex. Background Technology

[0002] Nitrile latex is made by copolymerizing butadiene and acrylonitrile emulsions. Because the copolymer molecular chain contains nitrile groups, it has good oil resistance, solvent resistance and chemical resistance. It has good adhesion to polar materials such as fibers and leather, and good compatibility with polar polymers such as starch, casein, vinyl resin, phenolic resin and urea-formaldehyde resin.

[0003] Utility model patent CN217614608U discloses a polymerization device for producing carboxylated nitrile butadiene latex. This utility model is equipped with a first feeding channel and a second feeding channel. Liquid materials can be added to the polymerization tank through the second feeding channel. The number of first feeding channels is determined according to the actual material requirements. This allows powdered materials and solid materials to be added to the polymerization tank separately through different first feeding channels. This avoids reactions between solid and liquid materials or their adhesion in the channels, and also avoids reactions between different materials that could cause channel blockage. This avoids production stoppages for maintenance, improves production efficiency, reduces labor, and brings convenience during production.

[0004] However, this carboxylated nitrile latex production polymerization device is not convenient for preheating and premixing materials during feeding, requiring more heating time before entering the polymerization tank. In addition, it is not convenient to improve the dispersion, emulsification and reaction efficiency of materials, thus affecting production efficiency. Utility Model Content

[0026] In this embodiment, the C servo motor 1101 drives the premixing rod 1102 to rotate, which on the one hand allows the raw materials to be fully preheated, and on the other hand premixes the raw materials.

[0027] Specifically, the drive assembly 6 includes a B servo motor 601, an A gear 602, a drive chain 603, and a B gear 604. The B servo motor 601 is fixedly installed on one side of the top surface of the vessel wall cleaning frame 502. The A gear 602 is fixedly installed at the output end of the B servo motor 601. The drive chain 603 meshes with the surface of the A gear 602. The B gear 604 meshes with the inside of the drive chain 603 on the side away from the A gear 602.

[0028] In this embodiment, servo motor B 601 drives gear A 602 to rotate, and drive chain 603 drives gear B 604 to rotate, so that the two sets of stirring rods 7 follow the rotation, and cooperate with servo motor A 501 to achieve dual motion stirring, promoting the dispersion and emulsification of raw materials.

[0029] Specifically, the inner wall of the inner liner 3 of the vessel has an installation cavity, and an electric heating ring 12 is fixedly installed inside the installation cavity. A temperature controller A is electrically connected to one side of the electric heating ring 12, and the temperature controller A is fixedly installed on the surface of the outer shell 1 of the vessel.

[0030] In this embodiment, the heating ring 12 heats the inner liner 3 of the vessel, and temperature controller A is used to control the temperature of the heating ring 12.

[0031] Specifically, a temperature controller B is electrically connected to one side of the heating rod 9, and the temperature controller B is fixedly installed on the surface of the feeding waiting hopper 8.

[0038] In this embodiment, the rotating column is used to limit the B gear 604 while facilitating its rotation.

[0039] The working principle and usage process of this utility model are as follows: First, the raw materials are put into the feeding waiting hopper 8. After the electric heating rod 9 is powered on, the raw materials are preheated to increase their temperature before entering the reaction vessel and improve the subsequent reaction efficiency. The C servo motor 1101 drives the premixing rod 1102 to rotate, which on the one hand allows the raw materials to be fully preheated, and on the other hand premixes the raw materials.

[0040] Then the valve is opened, and the preheated and premixed material enters the inner liner 3 of the reactor. The electric heating ring 12 heats the material in the inner liner 3. The aluminum silicate fiber layer 2 is used for heat insulation, reducing heat loss and saving energy. The outer shell 1 of the reactor further provides protection to prevent leakage of the discharged material.

[0041] Servo motor A 501 drives the vessel wall cleaning rack 502 to rotate, scraping off the material adhering to the inner liner 3 of the vessel. At the same time, it can drive the drive assembly 6 to rotate around the inner wall of the vessel. Servo motor B 601 drives gear A 602 to rotate, and drive chain 603 drives gear B 604 to rotate, so that the two sets of stirring rods 7 follow the rotation. Together with servo motor A 501, they achieve dual-motion stirring, which promotes the dispersion and emulsification of raw materials, so that the raw materials can be more fully and evenly mixed and reacted. After the reaction is completed, the raw materials are discharged through the discharge pipe 14.

[0042] In summary, this continuous polymerization production device for nitrile latex involves feeding raw materials into the feeding hopper 8, preheating the raw materials by energizing the heating rod 9 to increase their temperature before entering the reactor, thereby improving subsequent reaction efficiency. Servo motor C 1101 drives the premixing rod 1102 to rotate, ensuring both sufficient preheating and premixing of the raw materials. The preheated and premixed material then enters the reactor inner liner 3, where the heating ring 12 heats the material. The aluminum silicate fiber layer 2 provides insulation, and the outer shell 1 further protects the material. Servo motor A 501 drives the reactor wall cleaning rack 502 to scrape away the material adhering to the inner liner 3, while simultaneously driving the drive assembly 6 to rotate around the inner wall. Servo motor B 601 drives gear A 602 to rotate, and the drive chain 603 drives gear B 604 to rotate, causing the two sets of stirring rods 7 to follow the rotation, achieving dual-motion stirring in conjunction with servo motor A 501, promoting the dispersion and emulsification of the raw materials.
