Description

Technical Field

[0001] This utility model relates to a low-acidity acrylate compound neutralization device, specifically a low-acidity acrylate compound neutralization device, belonging to the technical field of acrylate processing equipment. Background Technology

[0002] The low-acidity acrylate compounding and neutralization device is a specialized piece of equipment used in the later stages of acrylate product production to achieve precise neutralization and compounding. Its core function is to reduce the acidity of acrylate materials to the target range and complete the component adjustment to ensure the stability of the final product quality.

[0003] The existing low-acidity acrylate compounding and neutralization devices have fixed stirring forces, ranges, and directions. This makes it difficult to break up local agglomerates of materials and to allow the compound neutralizing agent to quickly penetrate into all areas of the materials. As a result, the mixing efficiency is low and the uniformity is insufficient, which may affect the stability of subsequent compounding and neutralization reactions and the quality of the products. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a low-acidity acrylate compound neutralization device to solve the above-mentioned problems, thereby addressing the issue that the existing stirring mechanism cannot meet the mixing requirements of the materials and compound neutralizing agent in the reactor.

[0005] This utility model is achieved through the following technical solution: a low-acidity acrylate compound neutralization device.

[0006] The system includes two neutralization reactors. A condenser is installed on the outside of each reactor, and a circulation pump is installed on the outside of each reactor. A first delivery pipe is fixedly connected to the top of one circulation pump, and the first delivery pipe is connected to the other reactor. A second delivery pipe is fixedly connected to the outside of the other circulation pump. A first connecting pipe is fixedly connected to the top of one reactor, and one end of the first connecting pipe is connected to the other reactor. The two reactors, together with the delivery pipe and connecting pipe, enable material to flow between the reactors. The circulation pump accelerates material circulation, and the condenser can control the temperature in a timely manner, thereby improving the stability and efficiency of the reaction.

[0007] Preferably, a motor is fixedly connected to the top of the neutralization reactor. The bottom end of the motor's power output shaft passes through the neutralization reactor and extends into the inner cavity of the neutralization reactor. A mounting plate is fixedly connected to the bottom end of the motor's power output shaft. A mounting plate is fixedly connected to the bottom of the mounting plate. The motor provides stable power for stirring. The mounting plate and the mounting plate form the basic frame of the stirring mechanism, ensuring that the subsequent stirring components are firmly installed and operate stably.

[0008] Preferably, the top of the mounting plate is rotatably connected to two driven gears, and the bottom of the driven gears is fixedly connected to a mounting rod. The bottom end of the mounting rod passes through the mounting plate and extends to the bottom of the mounting plate. Multiple mixing plates are fixedly connected to the outside of the mounting rod, and the mixing plates are evenly distributed. The two driven gears drive the mounting rod to rotate synchronously, and the evenly distributed mixing plates expand the mixing range and improve the mixing uniformity of the material and the neutralizing agent.

[0009] Preferably, a fixing plate is fixedly connected to the inner cavity of the neutralization reactor, and a fixing rod is fixedly connected to the top of the fixing plate. The top end of the fixing rod passes through the mounting plate and extends into the inner cavity of the mounting plate. A toothed ring is fixedly connected to the top end of the fixing rod. The toothed ring meshes with two driven gears. The meshing of the fixed toothed ring with the driven gears causes the stirring component to rotate on its own axis while revolving around the motor shaft, forming a compound stirring motion and further enhancing the mixing effect.

[0010] Preferably, a pipeline mixer is provided on the outside of the neutralization reactor. Both ends of the pipeline mixer are provided with second connecting pipes. One end of the second connecting pipe on one side is connected to the neutralization reactor, and one end of the second connecting pipe on the other side is connected to the circulating pump on one side. The pipeline mixer and the circulating pump work together to perform secondary mixing during the material circulation process, making up for the blind spots in the stirring inside the reactor and improving the overall mixing efficiency.

[0011] Preferably, a phase separator is provided on one side of the neutralization reactor on the other side. The phase separator is connected to the second conveying pipe. The phase separator can separate oil and water in the reacted material to achieve the initial separation of the target product and impurities, laying the foundation for subsequent purification processes.

[0012] Preferably, a third conveying pipe is fixedly connected to the top of the phase separator, and a fourth conveying pipe is fixedly connected to the other side of the top of the phase separator. The two conveying pipes respectively convey substances of different phase states after phase separation, so as to avoid material mixing and ensure the purity of the separated materials.

[0013] Preferably, an aqueous phase transfer tank is provided on one side of the phase separator, and the aqueous phase transfer tank is connected to the third conveying pipe. A neutralized BA transfer tank is provided on one side of the aqueous phase transfer tank, and the neutralized BA transfer tank is connected to the fourth conveying pipe. A third connecting pipe is provided between the top of the aqueous phase transfer tank and the neutralized BA transfer tank. The dedicated transfer tanks store the aqueous phase and the neutralized BA product respectively to avoid cross-contamination. The third connecting pipe can realize emergency allocation or secondary treatment of materials between the two tanks, improving the operational flexibility of the device.

[0014] This invention provides a low-acidity acrylate compound neutralization device, which has the following beneficial effects: 1. This low-acidity acrylate compound neutralization device, through a multi-axis, multi-directional synchronous mixing mechanism, utilizes a composite motion mode of motor-driven mounting plate revolution and fixed gear ring meshing with driven gear rotation. This effectively breaks up the agglomeration of low-acidity acrylate raw materials. Multiple sets of evenly distributed mixing plates cover the entire reactor without dead zones, allowing the materials to quickly achieve molecular-level contact with the compound neutralizing agent. This design not only significantly shortens mixing time and effectively improves stirring efficiency, but also avoids localized neutralizing agent concentration imbalances, effectively reducing side reactions and ensuring that the final product's acidity, purity, and other key indicators consistently meet process requirements.

[0015] 2. This low-acidity acrylate compounding and neutralization device employs a dual-tank gradient reaction, circulation, reflux, buffer, and dilution mechanism. This mechanism uses differentiated reaction parameters set for each of the two tanks to create a stepped reaction process, gradually adjusting the acidity of the materials, reducing the intensity of individual reactions, and improving operational safety. Simultaneously, the circulation reflux system returns unreacted materials to the tanks for secondary reaction, reducing raw material waste; the buffer dilution function precisely controls the material concentration, preventing reaction runaway due to excessive concentration. Furthermore, the alternating operation of the two tanks balances equipment load, extends service life, ensures continuous and stable production, and reduces downtime for maintenance.

[0017] This invention provides a low-acidity acrylate compound neutralization device.

[0018] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The system includes two neutralization reactors 1. A condenser 101 is installed on the outside of the neutralization reactor 1. A circulation pump 102 is installed on the outside of the neutralization reactor 1. A first delivery pipe 103 is fixedly connected to the top of one circulation pump 102. The first delivery pipe 103 is connected to the other neutralization reactor 1. A second delivery pipe 104 is fixedly connected to the outside of the other circulation pump 102. A first connecting pipe 105 is fixedly connected to the top of one neutralization reactor 1. One end of the first connecting pipe 105 is connected to the other neutralization reactor 1.

[0019] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 A motor 2 is fixedly connected to the top of the neutralization reactor 1. The bottom end of the power output shaft of the motor 2 passes through the neutralization reactor 1 and extends into the inner cavity of the neutralization reactor 1. A mounting plate 201 is fixedly connected to the bottom end of the power output shaft of the motor 2. A mounting plate 202 is fixedly connected to the bottom of the mounting plate 201. Two driven gears 3 are rotatably connected to the top of the mounting plate 202. A mounting rod 301 is fixedly connected to the bottom of the driven gears 3. The bottom end of the mounting rod 301 passes through the mounting plate 202 and extends into the bottom of the mounting plate 202. Multiple mixing plates 302 are fixedly connected to the outer side of the mounting rod 301. The mixing plates 302 are evenly distributed. A fixing plate 4 is fixedly connected to the inner cavity of the neutralization reactor 1. A fixing rod 401 is fixedly connected to the top of the fixing plate 4. The top end of the fixing rod 401 passes through the mounting plate 202 and extends into the inner cavity of the mounting plate 201. A gear ring 402 is fixedly connected to the top end of the fixing rod 401. The gear ring 402 meshes with the two driven gears 3.

[0020] The mechanism uses motor 2 as its power source. The power output shaft of motor 2 drives the mounting plate 201 and the bottom mounting plate 202 to revolve around the central axis of the neutralization reactor 1. Simultaneously, a fixing rod 401 is fixed on the fixing plate 4 inside the neutralization reactor 1. The toothed ring 402 at the top of the fixing rod 401 meshes with two driven gears 3 at the top of the mounting plate 202. When the mounting plate 202 revolves with motor 2, the driven gears 3 rotate under the meshing action of the toothed ring 402, thereby driving the bottom mounting rod 301 and the uniformly distributed mixing plates 302 on the outside to rotate synchronously. Through the combined motion mode of revolution and rotation, the mixing plates 302 form a multi-directional intersecting stirring trajectory inside the reactor, realizing all-round shearing, tumbling and mixing of materials, effectively expanding the stirring range and improving the mixing uniformity.

[0021] Example 2, please refer to again. Figure 1 , Figure 2 , Figure 3 and Figure 4 A pipe mixer 5 is installed on the outside of the neutralization reactor 1. Both ends of the pipe mixer 5 are provided with second connecting pipes 501. One end of the second connecting pipe 501 on one side is connected to the neutralization reactor 1, and one end of the second connecting pipe 501 on the other side is connected to a circulating pump 102. A phase separator 6 is installed on one side of the neutralization reactor 1 on the other side. The phase separator 6 is connected to the second conveying pipe 104. A third conveying pipe 601 is fixedly connected to the top of the phase separator 6. A fourth conveying pipe 602 is fixedly connected to the other side of the top of the phase separator 6. A water phase transfer tank 7 is installed on one side of the phase separator 6. The water phase transfer tank 7 is connected to the third conveying pipe 601. A neutralization BA transfer tank 8 is installed on one side of the water phase transfer tank 7. The neutralization BA transfer tank 8 is connected to the fourth conveying pipe 602. A third connecting pipe 9 is installed between the tops of the water phase transfer tank 7 and the neutralization BA transfer tank 8.

[0022] Two neutralization reactors 1 are interconnected via a first connecting pipe 105 to allow for the exchange of top gaseous or light materials. Material transport between the reactors is achieved via a circulating pump 102 and a first conveying pipe 103, forming a dual-reactor linkage system. During the reaction, different reaction parameters, such as temperature and neutralizing agent concentration, can be set for the two reactors. The material circulates between the two reactors via the circulating pump 102, completing a gradient reaction. Simultaneously, the circulating pump 102 drives the material through a second connecting pipe 501 into a pipeline mixer 5, where secondary mixing and buffering dilution are completed during transport to prevent excessively high local concentrations. After the reaction, the material enters a phase separator 6 via another circulating pump 102 and a second conveying pipe 104, achieving phase separation. It then enters an aqueous phase transfer tank 7 and a neutralization BA transfer tank 8 via third and fourth conveying pipes 601 and 602, respectively. The two transfer tanks can be further mixed via a third connecting pipe 9, forming a closed-loop process from reaction to circulation to buffering to separation to mixing, ensuring a stable and controllable reaction.

[0023] Working Principle: Material Input and Initial Mixing: Low-acidity acrylate raw materials and composite neutralizing agents are respectively input into two neutralization reaction vessels 1. The top motor 2 is started, driving the mounting plate 201 and mounting disk 202 to revolve around the center of the vessel. Simultaneously, the driven gear 3 on the mounting disk 202 meshes with the gear ring 402 supported by the top fixing rod 401 of the fixing plate 4, driving the mounting rod 301 and the mixing plate 302 to rotate. Through the combined motion of revolution and rotation, the mixing plate 302 performs all-round shearing and turning of the materials in the vessel, achieving initial uniform mixing. Dual-vessel gradient reaction and circulation buffer: The two neutralization reaction vessels 1 are interconnected by the first connecting pipe 105. The circulation pump 102 on one side transports the material from one vessel to the other vessel through the first conveying pipe 103, forming a dual-vessel material circulation. Different parameters can be set for the two vessels, such as temperature and neutralizing agent addition. In the process of material circulation, a gradient neutralization reaction is completed to avoid violent single reactions. At the same time, the circulation pump 102 drives the material through the second connecting pipe 501 into the pipeline mixer 5, where secondary mixing and buffer dilution are completed during the transportation process to eliminate the problem of excessively high local concentrations. The condenser 101 outside the neutralization reactor 1 controls the temperature in real time to ensure a stable reaction environment. After the separation and transfer and blending reaction is completed, the circulation pump 102 on the other side sends the material through the second conveying pipe 104 into the phase separator 6. The phase separator 6 separates the material into oil and water. The separated aqueous phase enters the aqueous phase transfer tank 7 through the third conveying pipe 601, and the neutralized BA product enters the neutralized BA transfer tank 8 through the fourth conveying pipe 602. If secondary processing is required, the material can be blended through the third connecting pipe 9 at the top of the two transfer tanks, and finally the entire process of compound neutralization of low acidity acrylate is completed.
