A uniform stirring device for an acrylic resin production reactor

Abstract

This utility model relates to the technical field of acrylic resin synthesis equipment, and discloses a uniform stirring device for an acrylic resin production reactor. The device includes a reactor body with multiple air ducts connecting its upper and lower sides in a circular array. Each air duct has a fan installed at its lower end and a filter screen installed at its upper end. An LED control panel is installed on the outside of the reactor body. This utility model uses the fan to blow air into the air ducts. When the temperature inside the reactor exceeds a certain range due to the heat generated by the acrylic resin polymerization reaction, the fan automatically starts. Outside cold air passes through the air ducts into the reactor body, and the high temperature of the reactor body is dissipated through heat conduction with the air ducts, thus preventing the internal temperature of the reactor body from becoming too high and ensuring the optimal chemical reaction temperature required for the polymerization reaction is controlled within a more precise range.

Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology for acrylic resin, and in particular to a uniform stirring device for reaction vessel production of acrylic resin. Background Technology

[0002] The synthesis of acrylic resins is mainly based on free radical polymerization. Through monomer selection, initiator use, and control of process conditions within the reactor, macromolecular polymerization is achieved. In fact, polymerization is a chemically exothermic reaction, and the exothermic reaction is difficult to control, which may lead to branching or cross-linking. In addition, the reaction temperature has a significant impact on the polymerization rate. Higher reaction temperatures can cause the initiator to decompose faster, thereby accelerating the polymerization reaction, but at the same time, it may also lead to increased branching, higher degree of cross-linking, and even the formation of insoluble particles. Lower reaction temperatures will prolong the induction period and result in low initial conversion rates. The temperature usually needs to be controlled within the range of 80℃-150℃. However, existing reactors used for the synthesis of acrylic resins generally suffer from insufficient temperature control precision.

[0003] For example, Chinese utility model patent CN220878818U discloses an acrylic resin reactor. Although the design has a heating wire on the outside of the reactor body and an insulation shell on the outside of the heating wire, which can heat the reactor body to the optimal reaction temperature required for the reaction, a large amount of heat is released during the polymerization reaction. This may cause the temperature inside the reactor body to be too high, resulting in side reactions and affecting the synthesis efficiency.

[0004] Based on this, a uniform stirring device for the reaction vessel in the production of acrylic resin is proposed to solve the above problems. Utility Model Content

[0005] To address the technical problem of temperature control during the synthesis of acrylic resin, this invention provides a uniform stirring device for the reaction vessel in the production of acrylic resin.

[0006] This utility model is achieved using the following technical solution: a uniform stirring device for an acrylic resin production reactor, comprising a reactor body, with multiple air ducts connecting the upper and lower sides of the reactor body, the multiple air ducts being arranged in a circumferential array, a fan installed at the lower end of each air duct, a filter screen installed at the upper end of each air duct, an LED industrial control panel installed on the outside of the reactor body, a temperature sensor installed on one side of the reactor body, the LED industrial control panel being electrically connected to the temperature sensor, the multiple fans being electrically connected to the LED industrial control panel, a uniform stirring mechanism provided on the upper side of the reactor body, an electric heating mechanism provided on one side of the reactor body, and a pressure relief valve installed on the upper side of the reactor body.

[0007] As a further improvement to the above solution, the uniform stirring mechanism includes a motor fixedly connected to the upper side of the reactor body, the output end of the motor extending downward and fixedly connected to a transmission rod, the lower end of the transmission rod being fixedly connected to a propeller blade, and a turbulence-inducing mechanism being provided on the outer side of the plurality of air ducts.

[0008] As a further improvement to the above solution, the turbulence mechanism includes a fixed cylinder that is fixedly connected to the outer side of multiple air ducts. Multiple connecting rods are fixedly connected to the upper side of the fixed cylinder. A turbulence plate is rotatably connected to the outer side of each connecting rod. A limit support mechanism is provided at the upper end of the multiple connecting rods.

[0009] As a further improvement to the above solution, the limiting support mechanism includes a limiting plate that is fixedly connected to the upper ends of the plurality of connecting rods, and the limiting plate is rotatably connected to the outer side of the transmission rod.

[0010] As a further improvement to the above solution, a feeding pipe is connected to the upper side of the reactor body, and a sealing cap is provided at the upper end of the feeding pipe. A discharge pipe is connected to the lower side of the reactor body.

[0011] As a further improvement to the above solution, the electric heating mechanism includes a heating wire installed inside the reactor body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a fan to blow air into the air duct. When the heat generated by the polymerization reaction of acrylic resin causes the temperature inside the reactor to exceed a certain range, the fan will automatically start. Cold air from the outside passes through the air duct and into the reactor. The high temperature of the reactor is discharged through heat conduction with the air duct, thereby avoiding excessively high internal temperature of the reactor and ensuring the optimal chemical reaction temperature required for the polymerization reaction, which is controlled within a more accurate range.

[0014] 2. This utility model uses the rotation of the propeller blades to push the solution at the bottom of the reactor body upward at high speed along the fixed cylinder, and then flow outward between multiple connecting rods. When it encounters the baffle, it pushes the baffle to rotate, thereby making the stirring more uniform during the polymerization reaction of acrylic resin, which is conducive to improving the chemical reaction rate between monomers.

[0024] Please combine Figure 2 As shown, in this embodiment, three air ducts 11 are connected between the upper and lower sides of the reactor body 1. In other embodiments, different numbers can be set according to the situation to adapt to different heat dissipation requirements.

[0025] The three air ducts 11 are arranged in a circular array. Each air duct 11 is equipped with a fan 13 at its lower end and a filter 7 at its upper end. The filter 7 prevents abnormal objects from entering the air duct 11.

[0027] Please combine Figure 1 As shown, a temperature sensor 9 is installed on one side of the reactor body 1. The temperature sensor 9 can monitor the chemical reaction temperature inside the reactor body 1 in real time and transmit it to the LED industrial control panel 4. The LED industrial control panel 4 can display the internal temperature.

[0028] Please combine Figure 2As shown, the LED industrial control panel 4 is electrically connected to the temperature sensor 9, and the three fans 13 are electrically connected to the LED industrial control panel 4. A uniform stirring mechanism is provided on the upper side of the reactor body 1, an electric heating mechanism is provided on one side of the reactor body 1, and a pressure relief valve 8 is installed on the upper side of the reactor body 1.

[0029] Please combine Figure 2 As shown, the uniform stirring mechanism includes a motor 6 fixedly connected to the upper side of the reactor body 1. The output end of the motor 6 extends downward and is fixedly connected to a transmission rod 10. The lower end of the transmission rod 10 is fixedly connected to a propeller blade 14. A turbulence mechanism is provided on the outside of multiple air ducts 11.

[0030] Please combine Figure 2 As shown, the turbulence mechanism includes a fixed cylinder 12 that is fixedly connected to the outside of multiple air ducts 11. It should be noted that the lowest side of the fixed cylinder 12 is kept at a certain distance from the bottom of the reactor body 1, so that when the propeller blade 14 is started, the liquid can flow upward along the bottom of the fixed cylinder 12.

[0031] Please combine Figure 4 As shown, a plurality of connecting rods 17 are fixedly connected to the upper side of the fixed cylinder 12. A baffle 16 is rotatably connected to the outer side of each connecting rod 17. A limit support mechanism is provided at the upper end of the plurality of connecting rods 17.

[0034] Please combine Figure 2 As shown, the electric heating mechanism includes a heating wire 3 installed inside the reactor body 1;

[0035] The implementation principle of the uniform stirring device for the reaction vessel in the embodiment of this application is as follows: The monomers and initiators required for synthesizing acrylic resin are added into the reaction vessel 1 through the feeding pipe 5. First, the heating wire 3 is started to raise the temperature of the reaction vessel 1 to 80 degrees Celsius, and the optimal chemical reaction temperature is gradually reached. When the polymerization reaction proceeds at high speed and releases a large amount of heat, the temperature sensor 9 detects that the temperature inside the reaction vessel 1 is too high. At this time, each blower 13 is started to introduce outside air into each air duct 11. The heat inside the reaction vessel 1 is absorbed by the air cooling method, thereby achieving the cooling effect. At the same time, the motor 6 is started to drive the transmission rod 10 to rotate, which drives the propeller blade 14 to rotate, pushing the internal solution from the bottom of the reaction vessel 1 upward along the fixed cylinder 12. After encountering the resistance of the limiting plate 15, it flows outward along the gap between multiple connecting rods 17 and pushes the baffle plate 16 to rotate, thereby achieving the function of uniform stirring.
