[0053] In order to solve the deficiencies in the prior art, please refer to Figure 1 to Figure 6 , this embodiment provides a dispersion device.

[0056] The lifting mechanism 130 is installed on the outer top wall of the dispersion tank 100 .

[0057] The adjusting column 200 is arranged in the dispersion tank 100 and along the height direction of the dispersion tank 100. The adjusting column 200 is spaced apart from the dispersion component 110. Both ends of the adjusting column 200 are spaced apart from the inner wall of the dispersion tank 100 and are fixedly connected to the inner wall of the dispersion tank 100 by a connecting rod 210.

[0058] The adjusting column 200 is a hollow structure and is made of a transparent material. The piston is slidably fitted in the adjusting column 200. The plug rod 600 is fixedly connected to the piston. The plug rod 600 is located on the side of the piston close to the top of the dispersion tank 100. The plug rod 600 extends along the axial direction of the adjusting column 200. The plug rod 600 penetrates the top of the adjusting column 200 and continues to extend through the top wall of the dispersion tank 100. The plug rod 600 extends outside the dispersion tank 100. The plug rod 600 cooperates with the lifting mechanism 130 and is driven by the lifting mechanism 130 to realize the upward and downward movement of the plug rod 600. Sliding sealing treatment is performed between the plug rod 600 and the adjusting column 200, and between the plug rod 600 and the dispersion tank 100.

[0059] The outer ring wall of the piston is provided with a groove 310, which is located in the middle of the piston along the axial direction of the adjusting column 200, and the groove 310 extends continuously in a ring shape along the circumference of the piston. The visual module 700 and the light source are installed in the groove 310, and the visual module 700 is arranged toward the side wall of the adjusting column 200, and is used to obtain image data of the dispersed system in the dispersion tank 100 through the side wall of the adjusting column 200. The light source is used to fill in the light for the visual module 700, so that the visual module 700 can smoothly obtain image data of the required brightness.

[0060] The visual module 700 is electrically connected to the processor. The processor is used to determine the dispersion effect of the dispersion system according to the image data obtained by the visual module 700, so as to determine whether the dispersion meets the standard. Optionally, the processor can optimize its ability to judge whether the dispersion meets the standard by performing machine learning on the image data of the qualified dispersion system, and is not limited thereto.

[0061] In this embodiment, the top wall of the regulating column 200 is provided with a first liquid inlet 220, which is matched with a first valve 221. The side wall at the top of the regulating column 200 is also provided with a first liquid outlet 230, which is matched with a second valve 231.

[0062] The bottom wall of the regulating column 200 is provided with a second liquid inlet 240, and the second liquid inlet 240 is matched with a third valve 241. The side wall at the bottom end of the regulating column 200 is also provided with a second liquid outlet 250, and the second liquid outlet 250 is matched with a fourth valve 251.

[0063] The adjusting column 200 further has a first drainage tube 260 and a second drainage tube 270 .

[0064] One end of the first drainage tube 260 is communicated with the first liquid outlet 230 , and the other end thereof extends to the bottom end of the regulating column 200 .

[0065] One end of the second drainage tube 270 is communicated with the second liquid outlet 250 , and the other end thereof extends to the top end of the regulating column 200 .

[0066] Along the flow direction of the dispersed system in the dispersion tank 100 , the first drainage pipe 260 and the second drainage pipe 270 are both located at the rear side of the adjustment column 200 .

[0067] Further, the piston includes: a first plug body 320, a second plug body 330, a third plug body 340, a rotating ring 350, a cleaning ring 360, a fixed column 370, a sliding column 400, a rotating arm 500, a matching wheel 510, an extension arm 530 and a transmission gear 540. The plug rod 600 is connected to the third plug body 340.

[0068] The first plug body 320 and the second plug body 330 are both annular and spaced apart along the axial direction of the adjusting column 200 . The second plug body 330 is located below the first plug body 320 .

[0069] The third plug body 340 is cylindrical, and the outer diameter of the third plug body 340 is smaller than the inner diameters of the first plug body 320 and the second plug body 330. The first plug body 320 and the second plug body 330 are both arranged in an annular manner on the third plug body 340, and the first plug body 320, the second plug body 330 and the third plug body 340 are arranged coaxially.

[0070] The rotating ring 350 is sleeved on the third plug body 340 and is coaxially arranged with the third plug body 340. The first plug body 320 and the third plug body 340 and the second plug body 330 and the third plug body 340 are both rotatably matched with the rotating ring 350 and rotatably sealed. A groove 310 is formed between the first plug body 320 and the second plug body 330.

[0071] The fixing column 370 is parallel to and spaced from the third plug body 340 . The fixing column 370 is fixedly connected between the first plug body 320 and the second plug body 330 . The third plug body 340 and the fixing column 370 are fixedly connected via a fixing rod 371 .

[0072] The cleaning ring 360 is located in the groove 310 , and each rotating ring 350 is correspondingly provided with a cleaning ring 360 , and the cleaning ring 360 is coaxially fixedly connected to the rotating ring 350 . The outer ring wall of the cleaning ring 360 has an elastic cleaning layer 361 , and the elastic cleaning layer 361 extends continuously in a ring shape along the circumference of the cleaning ring 360 .

[0073] The elastic cleaning layer 361 of the cleaning ring 360 is in contact with the inner wall of the adjusting column 200, and is used to clean the inner wall of the adjusting column 200. Due to the existence of the fixing column 370, the elastic cleaning layer 361 is squeezed by the fixing column 370 at the fixing column 370, and the elastic cleaning layer 361 is elastically compressed by the fixing column 370 toward the side where the cleaning ring 360 is located. After passing through the fixing column 370, the elastic cleaning layer 361 elastically returns to its original position and is in contact with the inner wall of the adjusting column 200 again.

[0074] Among them, the elastic cleaning layer 361 and the fixed column 370 are both made of hygroscopic materials, and the fixed column 370 is a hard hygroscopic material. When selecting the materials of the elastic cleaning layer 361 and the fixed column 370, the elastic cleaning layer 361 and the fixed column 370 can absorb the liquid phase of the dispersed system in the dispersion tank 100. It can be flexibly selected according to actual conditions. Optionally, the fixed column 370 can also be composed of a hard non-hygroscopic column and a dilutable wrapping layer, but is not limited thereto.

[0075] The visual module 700 is installed on the third plug body 340 .

[0076] The third plug body 340 has an axial through hole, and the sliding column 400 is slidably fitted in the axial through hole with damping.

[0077] A rotating arm 500 is provided at both ends of the third plug body 340, one end of the rotating arm 500 is hinged to the edge of the end of the third plug body 340, and a rotating arm 500 is provided on the side of the first plug body 320 away from the second plug body 330 and on the side of the second plug body 330 away from the first plug body 320.

[0078] The matching wheel 510 is installed at the other end of the rotating arm 500 . The rotation axis of the rotating arm 500 is parallel to the rotation axis of the matching wheel 510 , and the rotation axes of the two are perpendicular to the axis of the adjusting column 200 .

[0079] The extension arm 530 is fixedly connected to one end of the rotating arm 500 away from the matching wheel 510 and extends along the length direction of the rotating arm 500 toward a side away from the matching wheel 510 , and the extension arm 530 extends toward the sliding post 400 .

[0080] A transmission gear 540 is installed on the side of the first plug body 320 away from the second plug body 330 and the side of the second plug body 330 away from the first plug body 320. The transmission gear 540 is in transmission cooperation with the rotating ring 350. The rotating ring 350 has an outer gear ring.

[0081] The mating wheel 510 is coaxially mated with a driving gear 520 .

[0082] Both ends of the sliding column 400 have a first flange 410 and a second flange 420, the first flange 410 and the second flange 420 are arranged at intervals, and the first flange 410 is located on a side of the second flange 420 away from the middle of the sliding column 400. The extension arm 530 extends between the first flange 410 and the second flange 420. Both ends of the axial through hole of the third plug body 340 have an expanded diameter section for making way for the first flange 410 and the second flange 420.

[0083] The piston has a first sliding stop point and a second sliding stop point.

[0084] During the dispersion process, the dispersion assembly 110 continuously stirs the dispersion system in the dispersion tank 100. The lifting group is used to drive the plug rod 600 to reciprocate up and down, so that the piston reciprocates between the top and bottom ends of the adjustment column 200.

[0085] During the reciprocating motion, the visual module 700 can collect image data of the dispersion conditions at different depths in the dispersion system, thereby improving the accuracy of the dispersion condition judgment.

[0086] When the piston is located at the first sliding stop point, the piston is located at the top end of the adjusting column 200 , the top end of the sliding column 400 abuts against the top wall of the adjusting column 200 , and the sliding column 400 is pushed toward the bottom end of the adjusting column 200 .

[0087] At this time, the first flange 410 at the top of the sliding column 400 pushes the top extension arm 530 downward, the top rotating arm 500 rotates and moves away from the first plug body 320, the top matching wheel 510 is separated from the inner wall of the adjusting column 200, and the top driving gear 520 is separated from the top transmission gear 540.

[0088] The second flange 420 at the bottom of the sliding column 400 pushes the extension arm 530 at the bottom downward, the rotating arm 500 at the bottom rotates and approaches the second plug body 330, the matching wheel 510 at the bottom fits with the inner wall of the adjusting column 200, and the driving gear 520 at the bottom meshes with the transmission gear 540 at the bottom.

[0089] In this state, if Figure 4 As shown, when the plug rod 600 continues to drive the piston to move downward, the matching wheel 510, the rotating ring 350, and the cleaning ring 360 at the top of the piston will not rotate, and the matching wheel 510 at the bottom of the piston will "travel" along the inner wall of the adjustment column 200 and rotate, thereby driving the cleaning ring 360 to rotate through the driving gear 520, the transmission gear 540 and the rotating ring 350. In this way, the elastic cleaning layer 361 at the bottom of the piston can continuously clean the inner wall of the adjustment column 200 by rotating, and absorb the liquid phase that may pass through the inner wall of the second plug body 330 and the adjustment column 200, thereby ensuring the clarity of the visual field of the visual module 700. Since it is moving downward at this time, only the rotation of the cleaning ring 360 at the bottom of the piston can effectively ensure the clarity of the visual field of the visual module 700.

[0090] At the same time, the piston moves downward, the first valve 221 opens, the second valve 231 closes, the third valve 241 closes, and the fourth valve 251 opens. The dispersed system enters the regulating column 200 from the first liquid inlet 220, and the dispersed system entering the regulating column 200 is located above the piston. The dispersed system originally located below the piston in the regulating column 200 enters the second drainage tube 270 from the second liquid outlet 250, and is discharged from the top of the regulating column 200.

[0091] When the piston moves to the second sliding stop point, the piston is located at the bottom end of the adjusting column 200 , the bottom end of the sliding column 400 abuts against the bottom wall of the adjusting column 200 , and the sliding column 400 is pushed toward the top end of the adjusting column 200 .

[0092] At this time, the second flange 420 at the top of the sliding column 400 pushes the top extension arm 530 upward, the top rotating arm 500 rotates and approaches the first plug body 320, the top matching wheel 510 fits with the inner wall of the adjusting column 200, and the top driving gear 520 meshes with the top transmission gear 540.

[0093] The first flange 410 at the bottom of the sliding column 400 pushes the extension arm 530 at the bottom upward, the rotating arm 500 at the bottom rotates and moves away from the second plug body 330, the matching wheel 510 at the bottom is separated from the inner wall of the adjusting column 200, and the driving gear 520 at the bottom is separated from the transmission gear 540 at the bottom.

[0094] In this state, if Figure 5 As shown, when the plug rod 600 continues to drive the piston to move upward, the matching wheel 510, the rotating ring 350, and the cleaning ring 360 at the bottom of the piston will not rotate, and the matching wheel 510 at the top of the piston will "travel" along the inner wall of the adjusting column 200 and rotate, thereby driving the cleaning ring 360 to rotate through the driving gear 520, the transmission gear 540 and the rotating ring 350. In this way, the elastic cleaning layer 361 at the top of the piston can continuously clean the inner wall of the adjusting column 200 by rotating, and absorb the liquid phase that may pass through the inner wall of the first plug body 320 and the adjusting column 200, thereby ensuring the clarity of the visual field of the visual module 700. Since it is moving upward at this time, only the rotation of the cleaning ring 360 at the top of the piston can effectively ensure the clarity of the visual field of the visual module 700.

[0095] At the same time, the piston moves upward, the first valve 221 is closed, the second valve 231 is opened, the third valve 241 is opened, and the fourth valve 251 is closed. The dispersed system enters the regulating column 200 from the second liquid inlet 240, and the dispersed system entering the regulating column 200 is located below the piston. The dispersed system originally located above the piston in the regulating column 200 enters the first drainage tube 260 from the first liquid outlet 230, and is discharged from the bottom end of the regulating column 200.

[0096] Through the above design, during the dispersion process, visual monitoring of the dispersion effect, promotion of mixing of the upper and lower dispersion systems, and clearing of the field of view of the visual module 700 are simultaneously completed, effectively ensuring the monitoring accuracy of the dispersion effect.

[0097] This embodiment also provides a process for preparing a high temperature resistant silicone polyether emulsion defoamer, which comprises the following steps:

[0098] S1, adding 20-45 parts by weight of pure water, 10-25 parts by weight of polyether ester polyol, and 15-20 parts by weight of block polyether into the dispersion tank 100 of the above-mentioned dispersion device, dispersing and emulsifying, and monitoring the emulsification progress through the processor of the dispersion device until fully emulsified;

[0099] S2, adding 3 to 7 parts by weight of an emulsifier and 2 to 5 parts by weight of a dispersant to the emulsified system of S1, and then dispersing and emulsifying, and after sufficient emulsification, adding 0.5 to 2 parts by weight of sodium hydroxide for esterification to obtain a first intermediate product;

[0100] S3, 10-12.5 parts by weight of pure water, 8-10 parts by weight of silicone grease, 0.3-0.6 parts by weight of hydroxyethyl cellulose ether, and 0.5-1 parts by weight of polyethylene oxide are dispersed and stirred;

[0101] S4, adding 1 to 3 parts by weight of triethanolamine and 2 to 5 parts by weight of polyacrylate to the system of S3 for thickening and fully dispersing to obtain a second intermediate product;

[0102] S5. The first intermediate product and the second intermediate product are mixed and emulsified, 0.3-0.5 parts by weight of a Kathon preservative is added, stirred, and allowed to stand to obtain a high temperature resistant silicone polyether emulsion defoamer.

[0103] The emulsifier is polyoxyethylene sorbitan monooleate, and the dispersant is any one of lauryl sulfate, sorbitol alkyl compound, polyacrylic acid derivative and polyoxyethylene alkylphenol ether.

[0104] This solution can effectively control the emulsification effect, so that the product quality of the high-temperature resistant silicone polyether emulsion defoamer finally obtained is more stable, the defective rate is effectively reduced, and the defoaming effect is improved.

[0105] In summary, the dispersing device provided in the embodiment of the present invention can accurately control the dispersing progress, effectively reduce the blindness in the dispersing operation process, and help to more accurately control the actual required dispersing time, which has positive significance for reducing time waste and improving production efficiency. The preparation process of the high temperature resistant silicone polyether emulsion defoamer provided in the embodiment of the present invention can accurately control the dispersing progress, effectively reduce the blindness in the dispersing operation process, effectively ensure the dispersing effect, and further improve the product performance of the high temperature resistant silicone polyether emulsion defoamer finally obtained.
