Technical Field
[0001] The present invention relates to the technical field of isopropanol polyoxyethylene ether production, and specifically to an ultrasonic-assisted synthesis device and synthesis process for isopropanol polyoxyethylene ether production. Background Art
[0002] Isopropanol polyoxyethylene ether is an important non-ionic surfactant, which is prepared by the addition reaction of isopropanol and ethylene oxide under specific conditions. This compound combines some characteristics of isopropanol and the hydrophilicity of the polyoxyethylene chain segment. Its molecular structure contains a lipophilic isopropyl group and a hydrophilic polyoxyethylene group, making it have good emulsifying, dispersing, wetting, and solubilizing properties.

[0003] When producing isopropanol polyoxyethylene ether, ultrasonic-assisted technology is required.

[0013] A synthesis process of isopropanol polyoxyethylene ether includes the following steps: S1: First, set the reaction formula, and store isopropanol and ethylene oxide in the elliptical reaction kettle through the access end; S2: The stirring unit will start to work to make the reactants fully mixed in the reaction kettle; S3: The ultrasonic units will start working simultaneously. Under the assistance of ultrasonic waves, isopropanol and ethylene oxide will undergo an addition reaction to produce polyoxyethylene isopropyl ether. S4: The rotating mechanism will eliminate the bubbles generated by stirring to prevent the bubbles from affecting the propagation of ultrasonic waves and the cavitation effect. S5: Finally, by opening the control valve, the reaction product will be transported to the subsequent processing equipment through the discharge pipe.
[0014] The beneficial effects of the present invention are as follows: 1. In the present invention, by setting up the ultrasonic units, the servo motor will drive the rotation of the rotating shaft, and then drive the first support rod and the first sliding block to rotate along the ring, so that the ultrasonic transducer can rotate around the elliptical reaction kettle, thereby changing the propagation direction and angle of the ultrasonic waves.

This method can flexibly optimize the distribution of the low-pressure area and the high-pressure area according to different stages and requirements of the reaction.
[0015] 2. In the present invention, by setting up the reaction kettle unit, by designing the shape of the reaction kettle as an ellipse, the surface curvature of the ellipsoidal reaction kettle changes continuously, which can make the ultrasonic waves generate more complex reflection and scattering paths when propagating inside it. This helps to more evenly disperse the ultrasonic energy in the reaction kettle, thereby optimizing the distribution of the low-pressure area and the high-pressure area, reducing the energy concentration area, and making the cavitation effect occur more evenly in the entire reaction system.
[0016] 3. In the present invention, by setting up the stirring unit, before the servo motor drives the rotation of the rotating shaft, the telescopic rod will drive the cross plate into the cross notch, so that the second rotating shaft will also be driven to rotate, so that the stirring ring stirs the reactants to make the reaction sufficient. However, during the stirring process, the bubbles originally present in the reaction system or the bubbles generated during the reaction will affect the propagation of ultrasonic waves and the cavitation effect.
[0017] 4. In the present invention, by setting up the rotating mechanism, the electric rotating rod will make the support plate rotate. During the rotation process, the reactants will pass through the inclined groove, and the bubbles in the reactant system will be punctured by the puncturing rod. At the same time, the electromagnetic blocks on both sides will alternately generate magnetic forces and adsorb the magnetic blocks, so that the second sliding block will move along the sliding column and drive the scraping plate to brush the outer surface of the inclined groove to prevent the inclined groove from being blocked due to the accumulation of reactants.

A power supply board 10 is fixedly connected to the bottom of the wire 9. A controller 11 is fixedly connected to the outer surface of the power supply board 10; When the present invention works, first, isopropanol and ethylene oxide are stored in the elliptical reaction kettle 31 unit. Then, the ultrasonic unit 5 will start to work around the elliptical reaction kettle 31 unit and drive the stirring to agitate the reactants. Under the auxiliary action of ultrasonic waves, isopropanol and ethylene oxide undergo an addition reaction to produce isopropanol polyoxyethylene ether.
[0031] As Figures 3-4 shown, the ultrasonic unit 5 includes a support frame three 51. A servo motor 52 is fixedly connected to the top of the support frame three 51.

[0032] After pouring isopropanol and ethylene oxide into the elliptical reaction kettle 31, the servo motor 52 will drive the rotating shaft 53 to rotate, thereby driving the support rod one 54 and the sliding block one 55 to rotate along the ring 7, so that the ultrasonic transducer 56 can rotate around the elliptical reaction kettle 31, thereby changing the propagation direction and angle of ultrasonic waves. By changing the position and angle of the transducer, the propagation direction and coverage range of ultrasonic waves are dynamically adjusted.

A control valve 36 is fixedly connected to one side of the bottom plate 35 away from the outlet pipe 37.
[0035] By designing the shape of the reactor as an ellipse, the surface curvature of the ellipsoidal reactor changes continuously, which can make the ultrasonic wave generate more complex reflection and scattering paths when propagating inside it. This helps the ultrasonic energy to be more evenly dispersed in the reactor, thereby optimizing the distribution of the low-pressure area and the high-pressure area, reducing the energy concentration area, and making the cavitation effect occur more evenly in the whole reaction system.
[0036] Isopropanol and ethylene oxide can be poured into the elliptical reactor 31 through the access end 34. After the reaction is completed, by opening the control valve 36, the reaction product can flow out through the outlet pipe 37.
[0037] The outer surface of the elliptical reactor 31 is fixedly connected to the top of the support frame one 2.
[0038] The specific working process is as follows: During operation, after pouring isopropanol and ethylene oxide into the elliptical reactor 31, the servo motor 52 will drive the rotation of the rotating shaft 53, and then drive the support rod one 54 and the sliding block one 55 to rotate along the ring 7, so that the ultrasonic transducer 56 can rotate around the elliptical reactor 31, thereby changing the propagation direction and angle of the ultrasonic wave. After the reaction is completed, by opening the control valve 36, the reaction product can flow out through the outlet pipe 37.
[0039] Embodiment Two, use Figures 1-9 The ultrasonic-assisted synthesis device and synthesis process for the production of isopropanol polyoxyethylene ether in one embodiment of the present invention will be described as follows.
[0040] As Figure 6 As shown in the figure, for the ultrasonic-assisted synthesis device and synthesis process for the production of isopropanol polyoxyethylene ether of the present invention, on the basis of Embodiment One, the stirring unit 4 includes a round tube 41. A rotating shaft two 42 is rotatably connected to the inner wall of the round tube 41. Support columns 43 are symmetrically arranged at both ends of the rotating shaft two 42. The outer surface of the support column 43 is fixedly connected to both ends of the rotating shaft two 42. A cross notch 44 is arranged on the outer surface of the support column 43 near one end of the cross plate 59. A stirring ring 45 is fixedly connected to the outer surface of the support column 43 away from one end of the cross plate 59. A rotating mechanism 46 is fixedly connected to the outer surface of the stirring ring 45.
[0041] Before the servo motor 52 drives the rotating shaft 53 to rotate, the telescopic rod 58 will drive the cross-shaped plate 59 into the cross-shaped notch 44, so that the second rotating shaft 42 will also be driven to rotate, so that the stirring ring 45 stirs the reactants to make the reaction sufficient.
[0042] The outer surface of the circular tube 41 is fixedly connected to the outer surface of the circular hole 32, and the shape of the cross-shaped notch 44 matches that of the cross-shaped plate 59.
[0043] As Figures 7-8 shown, the rotating mechanism 46 includes a support bar 461. An inner groove 462 is arranged on the outer surface of the support bar 461.

A poking rod 4611 is fixedly connected to the outer surface of the round rod 4610.
[0044] However, during the stirring process, the bubbles originally present in the reaction system or the bubbles generated during the reaction will affect the propagation of ultrasonic waves and the cavitation effect. When the stirring ring 45 is in a parallel state with the page, the servo motor 52 will stop working for a period of time, and at the same time, the electric rotating rod 463 will start to work, causing the support plate 464 to rotate. During the rotation process, the reactants will pass through the inclined groove 465, and the bubbles in the reactant system will be poked by the poking rod 4611.

[0046] At the same time, the electromagnetic blocks 8 on both sides will alternately generate magnetic forces and adsorb the magnetic block 468, so that the second sliding block 467 moves along the sliding column 466 and drives the scraping plate 469 to brush the outer surface of the inclined groove 465, preventing the inclined groove 465 from accumulating reactants and causing blockage.
[0047] Both ends of the support bar 461 are fixedly connected to the outer surface of the stirring ring 45, and the end of the scraping plate 469 away from the second sliding block 467 is slidably connected to the inner wall of the inclined groove 465.
[0048] A synthesis process of isopropanol polyoxyethylene ether includes the following steps: S1: First, set the reaction formula, and store isopropanol and ethylene oxide in the elliptical reaction kettle 31 through the access end 34; S2: The stirring unit 4 will start to work to fully mix the reactants in the reaction kettle; S3: The ultrasonic unit 5 will start working simultaneously. With the assistance of ultrasonic waves, isopropanol and ethylene oxide undergo an addition reaction to produce polyoxyethylene isopropyl ether. S4: The rotating mechanism 46 will eliminate the bubbles generated by stirring to avoid the influence of bubbles on the propagation and cavitation effect of ultrasonic waves. S5: Finally, by opening the control valve 36, the reaction product is transported to the subsequent processing equipment through the discharge pipe 37.
[0049] The specific working process is as follows: During operation, the telescopic rod 58 will drive the cross plate 59 into the cross notch 44, thereby driving the rotation of the second rotating shaft 42 as well, so that the stirring ring 45 stirs the reactants to make the reaction sufficient. When the stirring ring 45 is parallel to the liquid surface, the servo motor 52 will stop working for a period of time, and at the same time, the electric rotating rod 463 will start working to make the support plate 464 rotate. During the rotation, the reactants will pass through the inclined groove 465, and the bubbles in the reactant system will be punctured by the puncturing rod 4611. At the same time, the electromagnetic blocks 8 on both sides will alternately generate magnetic forces and adsorb the magnetic blocks 468, so that the second sliding block 467 moves along the sliding column 466 and drives the scraping plate 469 to brush the outer surface of the inclined groove 465.
