Abstract
Description
Technical Field
[0001] This utility model relates to the field of surfactant production technology, and in particular to a surfactant mixing device that can defoam. Background Technology
[0002] In the production and processing of surfactants, it is often necessary to mix multiple raw materials in a certain proportion. Currently, the surfactant mixing devices available on the market usually consist of a mixing tank, a stirring mechanism, a feed inlet, and a discharge outlet. The stirring mechanism mixes the multiple raw materials in the mixing tank.
[0003] Surfactants themselves have a certain degree of surface activity. During the mixing process, due to the violent collision between raw materials and the friction with the stirring components, a large amount of foam is easily generated. These foams contain a large amount of air, resulting in a large number of air bubbles inside the mixed material. On the one hand, the presence of air bubbles will make the raw materials not mixed evenly, affecting the dispersion effect of each component, and thus leading to unstable performance of the final product. On the other hand, foam will occupy a certain space in the mixing tank, reducing the effective volume of the mixing tank and affecting production efficiency. Moreover, materials with a large amount of foam may also cause problems such as overflow and stratification during subsequent storage, transportation and use, bringing many inconveniences to production. In addition, the generation of foam will also increase the volume of the material, causing errors in the metering and transportation process, affecting the accuracy of production. Therefore, a surfactant mixing device with defoaming capability is proposed to solve the above problems. Utility Model Content
[0004] (a) Purpose of the utility model
[0005] To address the technical problems existing in the background art, this utility model proposes a defoaming surfactant mixing device. By setting up a stirring mechanism to stir and mix the surfactant, during the mixing process, when bubbles encounter bubble-piercing needles due to the flow of surfactant, the bubbles can be pierced and broken by the bubble-piercing needles, which has a good defoaming effect on some larger bubbles. When bubbles encounter defoaming nets, the defoaming nets will intercept the bubbles, causing them to break. This can break smaller bubbles that cannot be reached by bubble-piercing needles, thus improving the defoaming effect of the defoaming structure, reducing the impact of bubbles on the mixing process, and ensuring uniform mixing of raw materials.
[0006] (II) Technical Solution
[0007] This utility model provides a defoaming surfactant mixing device, including a mixing tank, an internal defoaming structure, an internal stirring mechanism, an air extraction mechanism, and a feeding mechanism.
[0008] The defoaming structure includes a bubble-piercing mechanism and a bubble-breaking mechanism, both of which are symmetrically distributed inside the mixing chamber.
[0009] The bubble-piercing mechanism includes two first mounting blocks installed on the inner side wall of the mixing chamber. A first vertical block is installed on one side of the two first mounting blocks opposite to each other. A plurality of round rods are installed on the side of the first vertical block away from the mixing chamber. A plurality of evenly distributed bubble-piercing needles are installed on the outer side of the round rods.
[0010] The defoaming mechanism includes two second mounting blocks installed on the inner wall of the mixing tank. A second vertical block is installed on one side of the two second mounting blocks opposite to each other. Multiple frames are installed on the side of the second vertical block away from the mixing tank. Defoaming nets are installed on the inner side of the frames.
[0011] Preferably, the stirring mechanism includes a drive motor mounted on the top of the mixing chamber, a rotating rod extending into the mixing chamber is mounted on the output shaft of the drive motor, and a plurality of evenly distributed stirring rods are mounted on the outer side of the rotating rod.

[0013] Preferably, the air extraction mechanism includes a vacuum pump installed on the top of the mixing chamber, the air extraction port of the vacuum pump is connected to a connecting pipe, the other end of the connecting pipe extends into the interior of the mixing chamber, and an electric valve is installed inside the connecting pipe.
[0014] Preferably, the feeding mechanism includes a feeding pipe connected to the top of the mixing tank, a sealing cover plate is installed on the top of the feeding pipe, and meshing threads are provided on the outer side of the feeding pipe and the inner side of the sealing cover plate.

[0016] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0017] This defoaming surfactant mixing device uses a stirring mechanism to mix the surfactant. During the mixing process, as the surfactant flows, bubbles encountering bubble-piercing needles are punctured and broken, effectively defoaming larger bubbles. When bubbles encounter a defoaming net, the net intercepts and breaks them, thus breaking smaller bubbles that the bubble-piercing needles cannot reach. Through the cooperation of the bubble-piercing needles and the defoaming net, both large and small bubbles in the surfactant can be thoroughly broken, improving the defoaming effect of the defoaming structure, reducing the impact of bubbles on the mixing process, and ensuring uniform mixing of raw materials.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] like Figure 1-5 As shown, the present invention proposes a surfactant mixing device that can defoam, including a mixing tank 1, an internal defoaming structure, a stirring mechanism 2, an air extraction mechanism 3, and a feeding mechanism 6.
[0028] In this invention, the surfactant can be placed into the mixing tank 1 through the feeding mechanism 6, and the mixing tank 1 can hold the surfactant. After holding, the surfactant can be stirred by the stirring mechanism 2. During the stirring process, bubbles will appear inside the surfactant. When the surfactant is stirred, the surfactant and bubbles will also rotate and flow. When the surfactant and bubbles rotate and flow, the defoaming structure can eliminate the bubbles inside the surfactant. At the same time, the air extraction mechanism 3 can reduce the air pressure inside the mixing tank 1, reduce the generation of bubbles, and also eliminate the air in the generated bubbles, causing the bubbles to burst.
[0029] By combining the defoaming structure with the vacuuming mechanism 3, the bubbles inside the surfactant can be fully eliminated, improving the defoaming effect, reducing the impact of foam on the mixing process, and ensuring uniform mixing of raw materials.
[0030] like Figure 1-2 As shown, in an optional embodiment, the defoaming structure includes a bubble-piercing mechanism 4 and a bubble-breaking mechanism 5, both of which are symmetrically distributed inside the mixing chamber 1.
[0031] When the surfactant and bubbles are rotating and flowing, the bubble-piercing mechanism 4 can puncture the bubbles, while the bubble-breaking mechanism 5 can intercept the generated bubbles, thus breaking them up.
[0032] like Figure 2-3 As shown, in an optional embodiment, the bubble-piercing mechanism 4 includes two first mounting blocks 41 installed on the inner wall of the mixing tank 1. A first vertical block 42 is installed on the opposite side of the two first mounting blocks 41. A plurality of round rods 43 are installed on the side of the first vertical block 42 away from the mixing tank 1. A plurality of evenly distributed bubble-piercing needles 44 are installed on the outer side of the round rods 43.
[0033] When the surfactant is stirred, it will rotate and flow. At this time, the surfactant will also drive the bubbles to rotate and flow. When the bubbles rotate and flow, they will hit the bubble-piercing needle 44 and be pierced by the bubble-piercing needle 44. This has a good defoaming effect on some larger bubbles.
[0034] like Figure 2 and Figure 4 As shown, in an optional embodiment, the foam breaking mechanism 5 includes two second mounting blocks 51 installed on the inner wall of the mixing tank 1. A second vertical block 52 is installed on the opposite side of the two second mounting blocks 51. A plurality of frames 53 are installed on the side of the second vertical block 52 away from the mixing tank 1. A defoaming net 54 is installed on the inner side of the frame 53.
[0035] When the surfactant also causes the bubbles to rotate and flow, the bubbles will be intercepted by the defoaming net 54. When the bubbles encounter the defoaming net 54, they will break. The defoaming net 54 can break some smaller bubbles that cannot be reached by the bubble needle 44.
[0036] Specifically, the combination of bubble-piercing needle 44 and defoaming net 54 can fully break up large or small bubbles in the surfactant, improve the defoaming effect of the defoaming structure, reduce the impact of bubbles on the mixing process, and ensure uniform mixing of raw materials.
[0037] like Figure 2As shown, in an optional embodiment, the stirring mechanism 2 includes a drive motor 21 mounted on the top of the mixing tank 1, a rotating rod 22 extending into the interior of the mixing tank 1 mounted on the output shaft of the drive motor 21, and a plurality of evenly distributed stirring rods 23 mounted on the outer side of the rotating rod 22.
[0038] After the surfactant is added into the mixing tank 1 through the feeding mechanism 6, the drive motor 21 is started. The output shaft of the drive motor 21 will drive the rotating rod 22 to rotate. The rotating rod 22 will drive multiple stirring rods 23 to rotate. The multiple stirring rods 23 can fully stir the surfactant, so that the surfactant can be fully mixed.
[0039] like Figure 2 As shown, in an optional embodiment, multiple round rods 43 correspond to multiple frames 53 respectively, and multiple stirring rods 23 are staggered with multiple round rods 43 and multiple frames 53 in the vertical direction.
[0040] The staggered distribution ensures that multiple stirring rods 23 can rotate stably, avoiding the situation where multiple stirring rods 23 are limited by the round rod 43 and the frame 53. At the same time, the multiple round rods 43 and the multiple frame 53 can further improve the efficiency of bubble elimination.
[0041] like Figure 1 As shown, in an optional embodiment, the vacuum pump 3 includes a vacuum pump 31 mounted on the top of the mixing chamber 1. The vacuum pump 31 has a connecting pipe 32 at its exhaust port. The other end of the connecting pipe 32 extends into the interior of the mixing chamber 1. An electric valve is installed inside the connecting pipe 32.
[0042] During the stirring process of the surfactant, the inside of the mixing box 1 is first sealed by the feeding mechanism 6, then the electric valve is opened and the vacuum pump 31 is turned on. At this time, the vacuum pump 31 can extract the air in the mixing box 1, reduce the air pressure inside the mixing box 1, reduce the generation of bubbles, and at the same time eliminate the air in the generated bubbles, causing the foam to burst.
[0043] like Figure 1 and Figure 5 As shown, in an optional embodiment, the feeding mechanism 6 includes a feeding pipe 61 connected to the top of the mixing tank 1, a sealing cover plate 62 is installed on the top of the feeding pipe 61, and meshing threads 63 are provided on the outer side of the feeding pipe 61 and the inner side of the sealing cover plate 62.
[0044] When adding surfactant into the mixing tank 1, the sealing cover 62 needs to be rotated first, and the sealing cover 62 is disengaged from the feed pipe 61 by the meshing thread 63. At this time, the surfactant can be added into the mixing tank 1 through the feed pipe 61.
[0045] When the addition is complete and the vacuum pump 31 needs to be started, the sealing cover plate 62 needs to be rotated in the reverse direction. The sealing cover plate 62 is threaded to the top of the feed pipe 61 through the meshing thread 63. The top of the feed pipe 61 can be sealed by the sealing cover plate 62 to ensure the airtightness of the inside of the mixing box 1.
[0046] like Figure 1 As shown, in an optional embodiment, an observation window 7 is installed on the outside of the mixing box 1, a controller is provided on the outside of the mixing box 1, a discharge pipe 8 is connected to the bottom of the mixing box 1, a manual valve is provided inside the discharge pipe 8, and four evenly distributed bases 9 are installed on the bottom of the mixing box 1, with rubber anti-slip pads installed on the bottom of each of the four bases 9.
[0047] The mixing status of the surfactant and the amount of bubbles inside the mixing chamber 1 can be observed through the observation window 7. After the surfactant is mixed, the sealing cover 62 needs to be removed by thread to ensure that the air pressure inside the mixing chamber 1 is balanced with the external air pressure. At this time, the manual valve can be opened to discharge the mixed surfactant through the discharge pipe 8.
[0048] The mixing tank 1 can be supported by four bases 9, while the stability of the mixing tank 1 can be ensured by four rubber anti-slip pads.
[0049] The drive motor 21, vacuum pump 31, and electric valve are all electrically connected to the controller, which can control the drive motor 21, vacuum pump 31, and electric valve.
[0050] Working principle:
[0051] In use, this defoaming surfactant mixing device involves first rotating the sealing cover 62 to detach it from the feed pipe 61 via threads. Then, the surfactant can be added into the mixing chamber 1 through the feed pipe 61. After addition, the sealing cover 62 is threaded back onto the top of the feed pipe 61. Next, the drive motor 21, vacuum pump 31, and electric valve are activated. The drive motor 21 rotates multiple stirring rods 23, ensuring thorough mixing of the surfactant. During mixing, the surfactant also causes bubbles to rotate and flow. When these bubbles encounter bubble-piercing needles 44, they are punctured, effectively eliminating the foam. The bubbles generated during the mixing process are punctured. Simultaneously, the bubbles are intercepted by the defoaming net 54. When the bubbles encounter the defoaming net 54, they break. The defoaming net 54 can break smaller bubbles that the puncturing needle 44 cannot reach. Through the cooperation of the puncturing needle 44 and the defoaming net 54, both large and small bubbles in the surfactant can be fully broken, improving the defoaming effect of the defoaming structure, reducing the impact of bubbles on the mixing process, and ensuring uniform mixing of raw materials. In addition, the vacuum pump 31 can extract air from the mixing chamber 1 through the connecting pipe 32, reducing the internal air pressure of the mixing chamber 1, reducing the generation of bubbles, and also eliminating the air in the generated bubbles, causing the foam to break. After the mixing is completed, the drive motor 21, vacuum pump 31 and electric valve are turned off, and the sealing cover 62 is opened to ensure that the internal air pressure of the mixing chamber 1 is balanced with the external air pressure. At this time, the manual valve is opened, and the mixed surfactant can be discharged through the discharge pipe 8.
[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
