[0086] As described in the background art, the high shear mixing equipment in the prior art does not shear the materials sufficiently, thereby reducing the shearing effect on the materials, the mixing uniformity of the materials, and the shear mixing efficiency ratio of the materials.

[0087] The material may include a continuous phase solution and dispersed phase particles. The continuous phase solution may be composed of 99.49% (mass fraction, the same below) of deionized water, 0.50% of polyvinyl alcohol and 0.01% of sodium dodecyl sulfate. The dispersed phase particles may be polyacrylamide dry powder particles with a molecular weight of 3 million to 30 million, rich in amide groups, containing hydroxyl groups after hydrolysis, and soluble in water.

[0088] When evaluating emulsification properties, the Sauter mean diameter (d 32 ) and span are two key parameters. 32 It is the most commonly used average particle diameter, which means that the diameter is d 32 The hypothetical monodisperse droplet population has the same total volume and total surface area as the actual droplet population. On the other hand, span is a common parameter used to measure the range of droplet size distribution. The smaller its value, the better the uniformity of the emulsion. 32 The calculation formulas for and span are shown in formulas (1) and (2) respectively:

[0089]

[0090]

[0091] Here, m represents the number of intervals in the droplet size distribution, and n i and di represent the number and diameter of droplets in interval i, respectively, and d 10 d 50 and d 90 It is the droplet diameter when the cumulative distribution of droplet size is 10%, 50% and 90% respectively.

[0092] The reason for this problem is that the high shear mixing equipment in the prior art only has one shearing unit disposed inside. The material enters the shearing unit from the inlet, is sheared by one shearing unit, and is output through the output port connected to the shearing unit. Only one shearing unit is disposed, which easily leads to insufficient mixing and shearing of the material by the shearing unit, thereby reducing the uniformity and refinement of the mixing of the material, and thus requiring a longer shearing time to achieve a better mixing and shearing effect, thereby reducing the shearing and mixing efficiency of the high shear mixing equipment.

[0093] In response to the above technical problems, an embodiment of the present application provides a high shear mixing device, which uses a first shear unit, a second shear unit, and a third shear unit, so that the material can be mixed and sheared step by step through the first shear unit, the second shear unit, and the third shear unit, thereby increasing the number of shearing times of the material, thereby enabling the material to be fully sheared and mixed in the high shear mixing device.

[0094] Furthermore, by making the first shearing unit include a first shearing structure, the second shearing unit include a second shearing structure and a third shearing structure, and the third shearing structure being spaced apart on the outer peripheral side of the second shearing structure, the material can be sheared by two layers of shear structures in the second shearing unit, thereby improving the shearing efficiency of the second shearing unit and helping to further refine the particle size of the material before entering the third shearing unit, thereby further improving the shearing efficiency of the high shear mixing equipment.

[0095] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

The first housing segment 610, the second housing segment 620, and the third housing segment 630 are connected in a detachable manner, so that the first shearing unit 200, the second shearing unit 300, and the third shearing unit 400 can be disassembled and repaired separately.

[0103] In some examples, the first housing segment 610 and the second housing segment 620 can be detachably connected by bolts, and the second housing segment 620 and the third housing segment 630 can also be detachably connected by bolts.

[0105] By setting up the first shearing structure 210, the material can be preliminarily mixed and sheared by the first shearing structure 210 before entering the second shearing unit 300, thereby reducing the difficulty of shearing the material by the second shearing unit 300, thereby reducing the energy consumption of the high shear mixing equipment 10 and improving the mixing efficiency.

[0106] The second shearing unit 300 is connected to the first shearing unit 200, and the second shearing unit 300 may include a second shearing structure 310 and a third shearing structure 320.

The second shearing structure 310 is used for rotating shearing the material input by the first shearing unit 200, and the third shearing structure 320 is used for rotating shearing the material sheared by the second shearing structure 310.

[0107] By making the first shearing unit 200 include the first shearing structure 210, the second shearing unit 300 include the second shearing structure 310 and the third shearing structure 320, and the third shearing structure 320 is spaced apart on the outer peripheral side of the second shearing structure 310, the material can be sheared in the second shearing unit 300 by the two-layer shearing structure, which can improve the shearing efficiency of the second shearing unit 300, and help to further refine the particle size of the material before entering the third shearing unit 400, which can effectively reduce the number of times and time of operation of the equipment, help to reduce energy consumption and further improve the shearing efficiency of the high shear mixing device 10.

[0108] The third shearing unit 400 is connected to the second shearing unit 300 and is used to shear the material input by the second shearing unit 300 by rotation.

[0109] refer to Figure 2a , Figure 2b and Figure 3In some embodiments, the third shearing structure 320 and the second shearing structure 310 can be connected to each other. The third shearing unit 400 and the second shearing unit 300 can rotate simultaneously.

[0110] In an exemplary embodiment, the third shear unit 400 may include a fourth shear structure 410, a fifth shear structure 420 and a sixth shear structure 430. The sixth shear structure 430 is disposed at intervals on the outer circumference of the fifth shear structure 420, and the fifth shear structure 420 is disposed at intervals on the outer circumference of the fourth shear structure 410.

[0113] In this way, by making the number of shearing structures in the third shearing unit 400 greater than the number of shearing structures in the second shearing unit 300, the third shearing unit 400 can shear and mix the material more fully, thereby further improving the shearing and mixing effects.

[0114] refer to Figure 2a and Figure 2b In some embodiments, the high shear mixing device 10 may further include a driving unit 800, which is connected to the first shear structure 210, the second shear structure 310 and the fourth shear structure 410.

[0117] In some embodiments, the number of the first rotor teeth 2111 may be 14, and the tooth thickness of the first rotor teeth 2111 may be 10 mm.

[0118] refer to Figure 2a , Figure 2b , Figure 3 and Figure 4 The first shearing unit 200 may further include a first passage 220.

[0126] In some embodiments, the plurality of second openings 3121 can be spaced and evenly arranged along the circumferential direction of the sidewall of the second stator slot 312. The second openings 3121 can be rectangular in shape, and the rectangular second openings 3121 provide a maximum area of ​​surface shearing, which is helpful for shearing and mixing medium solid particles or medium viscosity liquids, such as the liquid and particles sheared by the first shearing unit 200, at which time the viscosity and particle size are reduced.

[0127] The jet in the rectangular second opening 3121 can extend to the vicinity of the inner wall of the shell 600, and the jet intensity, jet zone shear rate and turbulent kinetic energy dissipation rate are greater, which is more conducive to shearing and stirring and mixing the material.

[0128] In some embodiments, the second openings 3121 may include 15 hole groups, and the 15 hole groups are spaced and evenly arranged along the sidewall of the second stator slot 312 , and each hole group includes 2 second openings 3121 .

[0129] In some embodiments, the length of the rectangular second opening 3121 may be greater than or equal to 14 mm and less than or equal to 16 mm. For example, the length of the second opening 3121 may be one of 14 mm, 14.4 mm, 15 mm, 15.3 mm, and 15.8 mm, or the length of the rectangular second opening 3121 may be any value between greater than or equal to 14 mm and less than or equal to 16 mm.

[0130] The width of the rectangular second opening 3121 can be greater than or equal to 3 mm and less than or equal to 3.5 mm. For example, the width of the second opening 3121 can be one of 3 mm, 3.1 mm and 3.3 mm, or the width of the rectangular second opening 3121 can be any value between greater than or equal to 3 mm and less than or equal to 3.5 mm.

[0131] refer to Figure 2a , Figure 2b and, Figure 3 and Figure 5 In some embodiments, the third shear structure 320 may include a third toothed rotor 321 and a third stator slot 322 , wherein the third toothed rotor 321 is spaced apart on the outer peripheral side of the second stator slot 312 , and the third stator slot 322 is spaced apart on the outer peripheral side of the third toothed rotor 321 .

The plurality of third rotor teeth 3211 are spaced apart along the circumference of the third toothed rotor 321. When the third toothed rotor 321 rotates, the material between the third toothed rotor 321 and the outer side wall of the second stator slot 312 can flow from the space between two adjacent third rotor teeth 3211 to between the third toothed rotor 321 and the inner side wall of the third stator slot 322, and be sheared and mixed.

[0133] In some embodiments, the number of the third rotor teeth 3211 is equal to the number of the second rotor teeth 3111. The thickness of the third rotor teeth 3211 is less than the thickness of the second rotor teeth 3111. The number of the second rotor teeth 3111 and the number of the third rotor teeth 3211 may both be 19.

[0134] refer to Figure 3 In some embodiments, the outer diameter of the third toothed rotor 321 is greater than the outer diameter of the first toothed rotor 211. Thus, by making the outer diameter of the third toothed rotor 321 greater than the outer diameter of the first toothed rotor 211, the contact area between the third toothed rotor 321 and the material can be greater than the contact area between the first toothed rotor 211 and the material, so that the third toothed rotor 321 can shear the material more fully, thereby improving the shearing effect of the second shearing unit 300 on the material.

[0135] In some embodiments, the sum of the number of the second rotor teeth 3111 and the number of the third rotor teeth 3211 may be 38, the tooth thickness of the second rotor teeth 3111 may be 7.5 mm, and the tooth thickness of the third rotor teeth 3211 may be 7 mm.

[0136] refer to Figure 5 In some embodiments, a plurality of third openings 3221 are formed on the sidewall of the third stator slot 322, and the second shearing unit 300 may further include a second passage 330 communicating with the third openings 3221. The material in the third stator slot 322 is transported to the second passage 330 through the third openings 3221, and further transported to the third shearing unit 400 through the second passage 330.

[0137] In some embodiments, the shape of the third opening 3221 can be the same as that of the second opening 3121, the shape of the third opening 3221 can also be rectangular, the size of the third opening 3221 can be larger than the size of the second opening 3121, and the number of the third opening 3221 can also be greater than the number of the second opening 3121.

[0138] In some embodiments, the flow area of ​​the third opening 3221 is larger than that of the second opening 3121 , and the flow area of ​​the second opening 3121 is larger than that of the first opening 2121 , so as to improve the fluidity of the material in the second shearing unit 300 .

[0139] The second passage 330 is annular and is arranged on the outer peripheral side of the third stator slot 322. The third shearing unit 400 is provided with a second opening 450 connected to the second passage 330. The material flows through the second passage 330 to the second opening 450 on the third shearing unit 400 and flows into the fourth shearing structure 410 of the third shearing unit 400.

[0140] refer to Figure 2a , Figure 2b , Figure 3 and Figure 6In some embodiments, the fourth shear structure 410 may include a fourth toothed rotor 411 and a fourth stator slot 412, wherein the fourth toothed rotor 411 is disposed in the fourth stator slot 412.

[0141] A plurality of fourth rotor teeth 4111 are arranged at intervals along the circumference of the fourth toothed rotor 411. When the fourth toothed rotor 411 rotates, the material can flow from the range of the fourth toothed rotor 411 through the interval between two adjacent fourth rotor teeth 4111 to between the fourth toothed rotor 411 and the inner wall of the fourth stator slot 412, and the material is sheared and mixed.

[0142] The number of the fourth rotor teeth 4111 is greater than the number of the second rotor teeth 3111 , so that the number of cutting times of the material can be further increased, thereby improving the shearing effect of the third shearing unit 400 on the material.

[0143] refer to Figure 2a and Figure 2b , Figure 3 and Figure 6 In some embodiments, a plurality of fourth openings 4121 are formed on the side wall of the fourth stator slot 412 , and the material in the fourth stator slot 412 is transported to the fifth shearing structure 420 through the fourth openings 4121 .

[0144] In some embodiments, a plurality of fourth openings 4121 can be spaced and evenly arranged along the circumferential direction of the side wall of the fourth stator slot 412. The shape of the fourth opening 4121 can be square, and the number of the square fourth openings 4121 is greater than the number of the second openings 3121 and greater than the number of the third openings 3221. The flow area of ​​the square fourth openings 4121 is smaller than the flow area of ​​the second openings 3121, so that the side wall of the fourth stator slot 412 can have a larger opening area, so that the shear rate and turbulent kinetic energy dissipation rate near the shear head can be more evenly distributed and concentrated, which is suitable for preparing materials with smaller particle (or droplet, bubble) size, such as further shearing treatment of the material sheared by the second shearing unit 300.

[0145] Furthermore, the square fourth opening 4121 has a regular shape and good stability, making the overall structure more uniform and stable.

[0146] In some embodiments, the side length of the fourth square opening 4121 may be greater than or equal to 1.9 mm and less than or equal to 2.1 mm. For example, the side length of the fourth opening 4121 may be one of 1.9 mm, 2.0 mm, and 2.1 mm. The gap between the fourth tooth slot and the fourth toothed rotor 411 may be 1 mm. The number of the fourth openings 4121 may be 260.

[0147] refer to Figure 2a and Figure 2b , Figure 3 and Figure 6 In some embodiments, the fifth shear structure 420 may include a fifth toothed rotor 421 and a fifth stator slot 422 , wherein the fifth toothed rotor 421 is spaced apart on the outer peripheral side of the fourth stator slot 412 , and the fifth stator slot 422 is spaced apart on the outer peripheral side of the fifth toothed rotor 421 .

[0148] The fifth toothed rotor 421 is spaced apart from the side wall of the fifth stator slot 422 . The fifth toothed rotor 421 may include a plurality of fifth rotor teeth 4211 , and the number of the fifth rotor teeth 4211 is equal to the number of the fourth rotor teeth 4111 .

[0149] A plurality of fifth rotor teeth 4211 are arranged at intervals along the circumference of the fifth toothed rotor 421. When the fifth toothed rotor 421 rotates, the material can flow from the range of the fifth toothed rotor 421 through the interval between two adjacent fifth rotor teeth 4211 to between the fifth toothed rotor 421 and the inner wall of the fifth stator slot 422, and the material is sheared and mixed.

[0150] The number of the fifth rotor teeth 4211 is equal to the number of the fourth rotor teeth 4111 , so that the number of cutting times of the material can be further increased, thereby improving the shearing effect of the third shearing unit 400 on the material.

[0151] A plurality of fifth openings are formed on the side wall of the fifth stator slot 422, and the material in the fifth stator slot 422 is transported to the sixth shearing structure 430 through the fifth openings. The shape, number and size of the fifth openings are the same as those of the fourth openings 4121, and therefore, the specific information of the parameters such as the shape, number and size of the fifth openings will not be described in detail.

[0152] refer to Figure 2a and Figure 2b , Figure 3 and Figure 6 In some embodiments, the sixth shear structure 430 may include a sixth toothed rotor 431 and a sixth stator slot 432 , wherein the sixth toothed rotor 431 is spaced apart on the outer peripheral side of the fifth stator slot 422 , and the sixth stator slot 432 is spaced apart on the outer peripheral side of the sixth toothed rotor 431 .

[0153] The sixth toothed rotor 431 is spaced apart from the side wall of the sixth stator slot 432 . The sixth toothed rotor 431 may include a plurality of sixth rotor teeth 4311 . The number of the sixth rotor teeth 4311 is equal to the number of the fifth rotor teeth 4211 .

[0154] A plurality of sixth rotor teeth 4311 are arranged at intervals along the circumference of the sixth toothed rotor 431. When the sixth toothed rotor 431 rotates, the material can flow from the range of the sixth toothed rotor 431 through the interval between two adjacent sixth rotor teeth 4311 to between the sixth toothed rotor 431 and the inner wall of the sixth stator slot 432, and the material is sheared and mixed.

[0155] The number of the sixth rotor teeth 4311 is equal to the number of the fourth rotor teeth 4111 , so that the number of cutting times of the material can be further increased, thereby improving the shearing effect of the third shearing unit 400 on the material.

[0156] The side wall of the sixth stator slot 432 is provided with a plurality of sixth openings. The third shearing unit 400 may include a third passage 440 . The third passage 440 is connected to the discharge end 500 . The material output from the sixth openings is transported to the discharge end 500 through the third passage 440 .

[0157] It can be understood that the shape, quantity and size of the sixth opening are the same as those of the fifth opening. Therefore, the specific information of parameters such as the shape, quantity and size of the sixth opening will not be repeated.

[0158] The outer side of the sixth stator slot 432 has a third passage 440 which is in communication with the discharge end 500 .

[0159] refer to Figure 3 In some embodiments, the outer diameter of the sixth toothed rotor 431 is greater than the outer diameter of the third toothed rotor 321 .

[0160] In this way, by making the outer diameter of the sixth toothed rotor 431 larger than the outer diameter of the third toothed rotor 321, the contact area between the sixth toothed rotor 431 and the material can be made larger than the contact area between the third toothed rotor 321 and the material, so that the sixth toothed rotor 431 can shear the material more fully, thereby improving the shearing effect of the third shearing unit 400 on the material.

[0161] The flow area of ​​the sixth opening is greater than the flow area of ​​the third opening 3221. In some embodiments, the gap between the fourth toothed rotor 411 and the fourth stator slot 412 is equal to the gap between the fifth toothed rotor 421 and the fifth stator slot 422, and is equal to the gap between the sixth toothed rotor 431 and the sixth stator slot 432.

[0162] The tooth thickness of the sixth rotor tooth 4311 is smaller than the tooth thickness of the fifth rotor tooth 4211 , and the tooth thickness of the fifth rotor tooth 4211 is smaller than the tooth thickness of the fourth rotor tooth 4111 .

[0163] In other embodiments, the gap between the fourth toothed rotor 411 and the fourth stator slot 412 is smaller than the gap between the second toothed rotor 311 and the second stator slot 312, and the gap between the second toothed rotor 311 and the second stator slot 312 is smaller than the gap between the first toothed rotor 211 and the first stator slot 212. In this way, from the first shearing unit 200 to the third shearing unit 400, the tooth slot gap becomes smaller and smaller, and the smaller the gap through which the material passes, the less likely the material is to pass through, which can prevent the material from flowing back to the shearing unit of the previous level, thereby preventing the backflow.

[0164] In some embodiments, the sixth toothed rotor 431 , the fifth toothed rotor 421 and the fourth toothed rotor 411 are connected, the driving unit 800 is drivingly connected to the fourth toothed rotor 411 , and the driving unit 800 drives the fifth toothed rotor 421 and the sixth toothed rotor 431 to rotate by driving the fourth toothed rotor 411 .
