Description

Technical Field

[0001] This utility model relates to the field of fine chemical technology, and in particular to a defoaming device for the reaction process of emulsifier production. Background Technology

[0002] In the emulsifier processing, foam generation is a key issue affecting production efficiency and product quality. Due to the surface activity of emulsifiers, stirring, high temperature or acid and alkaline environments can easily lead to the formation of stable foam in the system. This not only occupies equipment space and reduces mass transfer efficiency, but may also cause overflow or product contamination. Traditional defoaming technologies such as mechanical defoaming are energy-intensive and have unstable effects, while chemical defoamers are highly efficient but have toxicity or compatibility issues. For example, polyether defoamers have a low foam breaking rate, and silicone defoamers require complex emulsification processes and are prone to failure due to incomplete emulsification.

[0003] In the existing technology, during the high-speed stirring process of the emulsifier, the oil phase, water phase and functional components of the emulsifier are usually mixed at high speed by the stirrer to form a uniform emulsion. Traditional stirring is prone to forming local stable bubbles, especially in high viscosity systems, and the aggregation of bubbles can easily lead to uneven emulsification.

[0004] Therefore, a defoaming device for the reaction process in emulsifier production is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a defoaming device for the reaction process of emulsifier production, which can solve the problems of incomplete bubble rupture and uneven emulsification caused by bubble aggregation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a defoaming device for the reaction process of emulsifier production, comprising a stirring tank, a support fixedly connected to the bottom of the stirring tank, a flow diversion and guiding mechanism movably connected to the inner side of the stirring tank, and a mixing and defoaming mechanism movably connected to the inner side of the flow diversion and guiding mechanism;

[0007] The diversion and guiding mechanism includes a main shaft rotatably connected to the inside of the mixing tank. A first ring frame is movably connected to the top of the outer side of the main shaft, and a second ring frame is movably connected to the bottom of the outer side of the main shaft. A first linkage tooth is rotatably connected to the bottom of the first ring frame, and a second linkage tooth is rotatably connected to the top of the second ring frame. A guide rod is fixedly connected to one side of each of the first and second linkage teeth. A drive tooth is fixedly connected to the top and bottom of the outer side of the main shaft. The drive tooth meshes with the outer side of the first and second linkage teeth. A reciprocating drive assembly is movably connected to the top of the main shaft, and the reciprocating drive assembly is movably connected to the top of the mixing tank.

[0008] Preferably, the mixing and defoaming mechanism includes a support ring fixedly connected to the outside of the main shaft, the support ring being disposed at the bottom of the first ring frame and at the top of the second ring frame.

[0009] Preferably, a conical paddle is fixedly connected to the outer side of the support ring, a first telescopic column is fixedly connected to the front side of the conical paddle, a second telescopic column is fixedly connected to the rear side of the conical paddle, and a small-hole screen is fixedly connected to the opposite side of the first telescopic column and the second telescopic column.

[0010] Preferably, compression springs are fixedly connected to the inner sides of both the first and second telescopic columns.

[0011] Preferably, the reciprocating drive assembly includes a servo motor fixedly connected to the top of the mixing tank, the output end of the servo motor being fixedly connected to an incomplete tooth, and the outer side of the incomplete tooth being movably connected to a transmission tooth.

[0012] Preferably, the transmission gear is fixedly connected to the top of the main shaft, and a torsion spring is fixedly connected to the bottom of the transmission gear, and the torsion spring is fixedly connected to the top of the mixing tank.

[0013] Preferably, the top of the mixing tank is fixedly connected to a feeding port.

[0014] Preferably, a discharge port is fixedly connected to the bottom of the mixing tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application solves the problem of uneven emulsification caused by bubble aggregation in traditional stirring by setting a diversion and guiding mechanism, and improves the uniformity and quality of the emulsion. The servo motor drives the incomplete tooth to rotate. When it meshes with the transmission tooth, it drives the main shaft and guide rod to rotate in the forward direction. The texture on the outer side of the guide rod guides the liquid from the top and bottom ends to the center, forming a turbulent state. When the toothless surface of the incomplete tooth disengages, the torsion spring causes the transmission tooth and the main shaft to rotate rapidly, driving the guide rod to rotate in the reverse direction. Although the guiding direction is still from both ends to the center, the overall guiding direction is opposite, forming a countercurrent vortex. The countercurrent vortex generated by the alternating forward and reverse rotation can effectively break the local stable state that is easily formed in traditional stirring. Especially for high viscosity systems, it can strongly disperse the aggregated bubbles, allowing the oil phase, water phase and functional components to mix fully in disordered movement.

[0017] 2. This application solves the problem of insufficient refining ability and difficulty in dispersing bubbles in high-viscosity scenarios by setting up a mixing and defoaming mechanism. By using a hollow conical paddle with a compression channel from a large opening to a small opening, the liquid is forced to pass through the small-hole screens on both sides when the main shaft rotates, achieving a double refining process. In conjunction with the vibration of the small-hole screen driven by the first and second telescopic columns, the bubbles and agglomerated particles attached to the high-viscosity liquid can be strongly broken, preventing them from forming a stable structure due to viscous resistance. Even if the main shaft rotates in the opposite direction, the hollow cavity and inclined curved surface of the conical paddle can still push the liquid displacement through shear force, and can also maintain the mixing function, making the emulsion particle size distribution more uniform and significantly improving the emulsion stability.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A defoaming device for the reaction process of emulsifier production includes a mixing tank 1, a support 2 fixedly connected to the bottom of the mixing tank 1, a flow diversion and guiding mechanism 3 movably connected to the inner side of the mixing tank 1, and a mixing and defoaming mechanism 4 movably connected to the inner side of the flow diversion and guiding mechanism 3.

[0028] The diversion and guiding mechanism 3 includes a main shaft 31 rotatably connected to the inside of the mixing tank 1. A first ring frame 32 is movably connected to the top of the outer side of the main shaft 31, and a second ring frame 33 is movably connected to the bottom of the outer side of the main shaft 31. A first linkage tooth 34 is rotatably connected to the bottom of the first ring frame 32, and a second linkage tooth 35 is rotatably connected to the top of the second ring frame 33. A guide rod 36 is fixedly connected to the corresponding side of the first linkage tooth 34 and the second linkage tooth 35. A drive tooth 37 is fixedly connected to the top and bottom of the outer side of the main shaft 31. The drive tooth 37 meshes with the outer side of the first linkage tooth 34 and the second linkage tooth 35. A reciprocating drive assembly 38 is movably connected to the top of the main shaft 31. The reciprocating drive assembly 38 is movably connected to the top of the mixing tank 1.

[0029] In this embodiment: During the high-speed mixing of the emulsifier, the oil phase, water phase, and functional components are typically mixed at high speed into a uniform emulsion using a stirrer. The materials required for emulsification are first added to the mixing tank 1 through the top feeding port 5 and allowed to mix. Once the specified mixing ratio is reached, the main shaft 31 is driven to rotate reciprocally by the reciprocating drive assembly 38. When the main shaft 31 rotates, the two drive teeth 37 on its outer side mesh with the three sets of linkage teeth at the bottom of the first ring frame 32 and the three sets of linkage teeth at the top of the second ring frame 33, respectively. When the main shaft 31 drives the drive teeth 37 to rotate, it also links the first linkage tooth 34 and the second linkage tooth 35 on the outer side. This causes multiple guide rods 36 on opposite sides of the two sets of linkage teeth to rotate. The texture on the outer side of the guide rods 36 can guide the liquid, guiding it from the top and bottom ends of the mixing tank 1 towards the center. Liquid that is not guided will flow back to the top and bottom and be guided again, thus creating a turbulent state inside the mixing tank 1. When the main shaft 31 rotates in the opposite direction, although the texture of the guide rods 36 is the same, the guiding direction is still from the two ends to the center, but the overall guiding direction is opposite to that before. This can form a countercurrent vortex opposite to the original guiding direction, further guiding and mixing the liquid in the tank, making it in a near-disordered moving state.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 6 As shown, the mixing and defoaming mechanism 4 includes a support ring 41 fixedly connected to the outside of the main shaft 31. The support ring 41 is located at the bottom of the first ring frame 32 and at the top of the second ring frame 33.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 6 As shown, a conical paddle 42 is fixedly connected to the outer side of the support ring 41, a first telescopic column 43 is fixedly connected to the front side of the conical paddle 42, a second telescopic column 44 is fixedly connected to the rear side of the conical paddle 42, and a small hole screen 45 is fixedly connected to the opposite side of the first telescopic column 43 and the second telescopic column 44.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 6 As shown, compression springs 46 are fixedly connected to the inner sides of both the first telescopic column 43 and the second telescopic column 44.

[0033] In this embodiment, instead of using a traditional stirring roller, multiple conical paddles 42 supported by support rings 41 are installed at the center of the outer side of the main shaft 31. These conical paddles 42 are entirely hollow, with a large opening at one end and a small opening at the other. On both sides of the conical paddle 42, small-hole screens 45 supported by a first telescopic column 43 and a second telescopic column 44 are respectively provided. When the main shaft 31 rotates to one side, causing the end with the larger opening to rotate clockwise, the liquid is forced into the conical paddle 42 through the small-hole screens 45. It is then squeezed from the large opening towards the small opening, and after passing through the small opening... After passing through the orifice, the liquid can pass through the small-hole sieve 45 again, thereby achieving double refinement and squeeze diversion. Moreover, when the liquid comes into contact with the small-hole sieve 45, the first telescopic column 43 and the second telescopic column 44 between the small-hole sieve 45 and the conical paddle 42 will stretch and contract, which will allow the compression spring 46 inside them to accumulate elastic potential energy. Then the compression spring 46 rebounds, causing the small-hole sieve 45 on both sides to be in a state of vibration, thereby further improving the refinement effect. In addition, when the main shaft 31 rotates in the opposite direction, although the liquid cannot completely achieve the above effects, the conical paddle 42 still has the function of stirring and mixing.

[0034] Specifically, such as Figure 3 , Figure 4 As shown, the reciprocating drive assembly 38 includes a servo motor 38a fixedly connected to the top of the mixing tank 1. The output end of the servo motor 38a is fixedly connected to an incomplete tooth 38b, and the outer side of the incomplete tooth 38b is movably connected to a transmission tooth 38c.

[0035] Specifically, such as Figure 3 , Figure 4 As shown, the transmission gear 38c is fixedly connected to the top of the main shaft 31, and the bottom of the transmission gear 38c is fixedly connected to the torsion spring 38d, which is fixedly connected to the top of the mixing tank 1.

[0036] In this embodiment: by starting the servo motor 38a installed on the top of the mixing tank 1, the incomplete tooth 38b at the output end of the servo motor 38a starts to rotate. When the incomplete tooth 38b rotates, its toothed side will contact and mesh with the transmission tooth 38c on the top of the main shaft 31, causing the transmission tooth 38c to rotate to one side. Since the transmission tooth 38c is connected to the main shaft 31 at the center of the mixing tank 1, it will drive the main shaft 31 to rotate together through the transmission tooth 38c. When the incomplete tooth 38b rotates to the toothless side, it will disengage from the transmission tooth 38c. At this time, the transmission tooth 38c will tighten the torsion spring 38d between itself and the outer wall of the mixing tank 1 during the previous rotation. Therefore, after disengaging, the torsion spring 38d will rebound and drive the transmission tooth 38c and the main shaft 31 at its bottom to rotate rapidly in the opposite direction. At the same time, through the above linkage, the entire guide rod 36 will rotate in the opposite direction together.

[0037] Specifically, such as Figure 2 As shown, the top of the mixing tank 1 is fixedly connected to the feeding port 5.

[0038] Specifically, such as Figure 1 , Figure 2 As shown, a discharge port 6 is fixedly connected to the bottom of the mixing tank 1.

[0039] In this embodiment, feeding and receiving can be achieved through the feeding port 5 and the discharging port.

[0040] Working principle: In the high-speed mixing stage of the emulsifier, the oil phase, water phase, and functional components of the emulsifier are usually mixed at high speed by a stirrer to form a uniform emulsion. First, the required emulsifier is added into the mixing tank 1 through the feeding port 5 at the top of the mixing tank 1 for mixing. After the specified mixing ratio is reached, the servo motor 38a located at the top of the mixing tank 1 is activated first, causing the incomplete tooth 38b located at the output end of the servo motor 38a to rotate. When the incomplete tooth 38b rotates, its tooth surface contacts the transmission tooth 38c at the top of the main shaft 31, and thus meshes with the transmission tooth 38c, causing the transmission tooth 38c to rotate to one side. The transmission tooth 38c is connected to the main shaft 31 at the center of the mixing tank 1. The transmission gear 38c drives the main shaft 31 to rotate. When the main shaft 31 rotates, two drive teeth 37 are located on its outer side. These drive teeth 37 mesh with three sets of linkage teeth at the bottom of the first ring frame 32 and three sets of linkage teeth at the top of the second ring frame 33. The main shaft 31 drives the drive teeth 37, which in turn link the first linkage teeth 34 and the second linkage teeth 35 on their outer sides. This linkage causes multiple guide rods 36 on the opposite side of the first linkage teeth 34 and the second linkage teeth 35 to rotate. The textured outer surface of the guide rods 36 guides the liquid, directing it from both the top and bottom ends towards the center of the mixing tank 1. Unguided liquid is then further guided. The new guides continue to operate from the top and bottom of the mixing tank 1, creating a turbulent flow inside the tank. When the incomplete tooth 38b rotates to the toothless surface, it disengages from the drive tooth 38c. Since the drive tooth 38c tightens with the torsion spring 38d between itself and the outer wall of the mixing tank 1 during its previous rotation, after disengagement, the drive tooth 38c and its bottom main shaft 31 quickly rotate under the rotation of the torsion spring 38d, generating a reverse rotation. This, in conjunction with the aforementioned action, drives the overall guide rod 36 to rotate in the opposite direction. Although the guiding direction remains from both ends to the center due to the same texture, the overall guiding direction is reversed, thus creating a counter-current vortex opposite to the original guiding direction. The liquid inside the mixing tank 1 is further guided and mixed, resulting in a slightly disordered movement state. Instead of a traditional stirring roller, multiple conical paddles 42 supported by support rings 41 are installed at the center outside the main shaft 31. These conical paddles 42 are entirely hollow, with one end having a larger opening and the other a smaller opening. Small-hole screens 45, supported by a first telescopic column 43 and a second telescopic column 44, are installed on both sides of each paddle. When the main shaft 31 rotates to one side, connecting the larger opening clockwise, the liquid is forced through the small-hole screens 45 into the conical paddles 42, being squeezed from the larger opening to the smaller opening. After passing through the smaller opening, the liquid passes through the small-hole screens 45 again, achieving double refinement and squeeze diversion. Furthermore, when the liquid contacts the small-hole screens 45…Both the first telescopic column 43 and the second telescopic column 44 between the small-hole sieve 45 and the conical paddle 42 will stretch and contract, causing the internal compression spring 46 to accumulate elastic potential energy and rebound, so that the small-hole sieve 45 on both sides is in a state of vibration, thereby further optimizing the refining effect. Secondly, when the main shaft 31 rotates in the opposite direction, although the liquid cannot achieve the effect completely, the conical paddle 42 still has the function of stirring and mixing. In summary, the high-frequency switching of the bidirectional vortex fluid direction disrupts the surface tension balance of the bubbles, promotes bubble breakage, and forms disordered turbulence, preventing bubbles from accumulating locally. At the same time, the fluid shear force tears larger bubbles. Secondly, when the liquid passes through the small-hole sieve 45, the narrow channel generates high shear force, cutting large bubbles into microbubbles, reducing the bubble size for dissolution. Finally, the elastic deformation of the compression spring 46 causes the small-hole sieve 45 to vibrate at high frequency, further disrupting the stability of the bubble film, especially for bubbles that are difficult to break in viscous systems, thereby optimizing the process of efficient stirring in emulsifier production.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
