Description

Technical Field

[0001] This invention relates to the field of organic coating preparation and nanomaterial dispersion technology, and more specifically, to an ultrasonically enhanced dispersion device for nanofillers in organic coatings. Background Technology

[0002] With the development of functionalized organic coatings, inorganic nanofillers such as nano-silica, nano-titanium dioxide, nano-zinc oxide, and nano-clay are increasingly being introduced into coating systems to improve the coating's wear resistance, corrosion resistance, UV aging resistance, and additional functions such as self-cleaning and antibacterial properties. However, due to their large specific surface area and high surface energy, nanofillers are prone to agglomeration and clumping, making it difficult to form a stable and uniform dispersion in organic resin matrices.

[0003] In existing technologies, the dispersion of nanofillers typically employs mechanical methods such as high-speed shear stirring, bead milling, or sand milling, or is pre-dispersed using simple ultrasonic trough oscillation. These methods have the following drawbacks: Firstly, relying solely on mechanical shearing or ordinary ultrasound is insufficient to break up nanoparticle aggregates in a short time, resulting in low dispersion efficiency and requiring long grinding times and significant energy consumption. Secondly, prolonged high shearing and ultrasonic action can lead to a rapid increase in system temperature, easily causing changes in coating viscosity, solvent evaporation, and even resin degradation. Existing equipment generally lacks effective heat dissipation structures, making it difficult to stabilize product performance. Furthermore, many traditional dispersion devices only achieve single-unit operation: for example, independent stirring tanks, independent ultrasonic dispersers, and independent static mixers. Materials need to be transferred multiple times between different devices, resulting in long process flows, pipeline residues, secondary pollution, and operational complexity.

[0004] Therefore, we propose an ultrasonic-enhanced dispersion device for nanofillers in organic coatings to solve the above problems. Summary of the Invention

[0010] In a preferred embodiment, the ultrasonic vibrator includes a mounting ring coaxially mounted on the side wall of the throat, a fixing ring welded to the connection between the mounting ring and the throat, a conductor ring coaxially sleeved on the mounting ring, an amplitude transformer ring coaxially sleeved on the conductor ring, and multiple ultrasonic transducers mounted on the amplitude transformer ring.

[0011] In a preferred embodiment, the mechanical vibration component includes a rotating ring fixedly connected to the inner wall of the throat. The rotating ring has a rotating groove on its side wall, and multiple matching annular blocks are provided in the rotating groove. A first connecting rod is fixedly connected to the side wall of each of the multiple annular blocks. One end of the multiple first connecting rods is fixedly connected to the same connecting seat. A first impeller is installed on the side wall of the connecting seat. A first vertical rod is fixedly connected to the lower end of the connecting seat. An eccentric block is installed on the side wall of the first vertical rod.

[0012] In a preferred embodiment, the heat sink includes an annular groove on the side wall of the throat tube, in which multiple first strong magnetic blocks capable of rotating along the groove opening are provided.

A demister is installed on the side wall of the overflow cylinder, and multiple overflow ports are provided on the side wall of the overflow cylinder. An output pipe is installed at the output end of the output cylinder, and an exhaust pipe for venting is installed on the output cylinder.

[0015] The technical effects and advantages of this invention are as follows: 1. The device consists of a support frame, input component, conveying component, ultrasonic vibration component, mechanical vibration component, heat dissipation component, flow guiding and mixing component, and output component. The material undergoes feeding premixing, Venturi high shear, ultrasonic and mechanical composite dispersion, static flow guiding and mixing, and defoaming and venting in the same set of equipment in sequence. It avoids the transfer loss and process complexity caused by multiple equipment connected in series in traditional processes. It has a compact structure, small footprint, and is convenient for continuous industrial production.

[0016] 2. The feed dispersion seat, guide plate, and feed cylinder of the input component together constitute a tangential feed structure. The liquid material enters the feed cylinder tangentially, forming a strong swirling flow. The baffle, vertical cylinder, and baffle plate in the agitator form an internal and external circulation flow field of "outer ring swirling downward - vertical cylinder upward - top overflow and re-enter the outer ring". With the staggered arrangement of the bottom collection seat and the first connecting pipe, the residence time of the material in the feed cylinder is effectively extended, which significantly improves the premixing and de-agglomeration effect of the nanofiller before entering the Venturi high shear zone, laying the foundation for subsequent fine dispersion.

[0017] 3. The Venturi structure causes high-speed flow and pressure drop of materials within the throat, generating strong shearing and turbulence. The mechanical vibration component, without an external motor, can generate periodic mechanical vibration in the throat solely through fluid kinetic energy. Superimposed on the high-speed shearing, it further breaks down particles and agglomerates. The ultrasonic vibration component efficiently couples the vibration of a standard ultrasonic vibrator to the throat wall, forming a stable ultrasonic cavitation field. Together with the mechanical vibration, it generates cavitation impact and micro-jet shearing on the nanofiller, resulting in a dispersion efficiency significantly higher than that of a single mechanical or ultrasonic method.

[0018] 4. The heat sink achieves magnetic coupling transmission of "inner fluid drive and outer fan passive rotation". The heat sink fan blades enhance the air flow around the heat sink outside the throat. With the heat conduction of the heat sink, it can remove the heat generated by the Venturi throat and ultrasonic area in time, effectively suppress the liquid temperature rise during dispersion, protect the stability of the heat-sensitive organic coating system, and extend the service life of the ultrasonic transducer.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figure 1 , Figure 2 and Figure 3An ultrasonically enhanced dispersion device for nanofillers in organic coatings includes a support 1, which includes a base 11. A first support seat 12 is fixedly connected to the upper end of the base 11. Multiple support rods 13 are fixedly connected to the first support seat 12. A fixing sleeve 14 is fixedly connected to the upper end of the multiple support rods 13. A second support seat 15 is fixedly connected to the fixing sleeve 14. It is particularly noteworthy that the support 1 is a support device for supporting other components in the device, further ensuring the stability of the device.

[0023] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 The input component 2 includes an input cylinder 21 installed in the fixed support 14 and the second bracket 15. The input end of the input cylinder 21 is fixedly connected to a feeding dispersion seat 22. It is particularly noteworthy that the feeding dispersion seat 22 is provided with a flow guide seat, which further ensures that the liquid is discharged from the flow guide seat and avoids the liquid from accumulating in the feeding dispersion seat 22. The output end of the feeding dispersion seat 22 is fixedly connected to a flow guide plate 23, and the output direction of the flow guide plate 23 is aligned with the side wall of the input cylinder 21. The input end of the feeding dispersion seat 22 is fixedly connected to a feeding pipe 24. The input cylinder 21 is provided with a stirring component 25, and the stirring component 25 is provided with a first connecting pipe 26. Reference Figure 7 The stirring component 25 includes multiple baffles 251 fixedly connected to the side wall of the input cylinder 21 and arranged in a ring array. Multiple first foot blocks 252 are fixedly connected to the inner bottom of the stirring component 21. The upper ends of the multiple first foot blocks 252 are fixedly connected to the same vertical cylinder 253. Multiple baffles 254 are fixedly connected to the inner bottom of the input cylinder 21. The multiple baffles 254 are arranged in a ring array on one side of the output end of the input cylinder 21. The output end of the input cylinder 21 is fixedly connected to a collection seat 255 for installing the first connecting pipe 26.

[0024] More specifically, when material enters the feed pipe 24 through the external pump body, it directly impacts the guide seat. The guide seat is designed not only to buffer the impact force of the material but also to prevent liquid residue in the feed dispersion seat 22. The liquid can be discharged from the feed dispersion seat 22. With the assistance of the guide plate 23, the liquid material can enter the input cylinder 21 tangentially, forming a strong vortex. The swirling liquid flows downward along the tank wall, bypasses the bottom of the vertical cylinder 253 at the bottom of the tank, and enters the interior of the vertical cylinder 253 from the outer ring. The liquid then flows upward back up along the interior of the vertical cylinder 253, overflows from the top of the vertical cylinder 253, and is again tangentially guided into the outer ring. The reciprocating circulation between the inner and outer rings and the baffle plate 23... The turbulence effect of 54 creates a continuous three-dimensional circulation inside the tank, resulting in a strong stirring effect. It is particularly noteworthy that the diameter of the output end of the input cylinder 21 is smaller than the diameter of the vertical cylinder 253. The fluid coming from the bottom of the vertical cylinder 253 will first hit the baffle plate 254 and be thrown to the side, making it difficult to be directly sucked into the output end. The output end draws water from the side of the baffle plate 254, which is equivalent to taking a detour. At the same time, the arrangement of the collection seat 255 and the first connecting pipe 26 allows the liquid to flow around the collection seat 255 at the bottom before going down. This increases the path and reduces the direct flow, thereby increasing the time for the liquid to flow in the input cylinder 21. This further increases the time for the liquid to be stirred and mixed in the input cylinder 21, thereby improving the mixing effect of the liquid. Reference Figure 8 and Figure 9 The conveying component 3 includes a shrink tube 31 disposed below the fixed sleeve plate 14. The output end of the shrink tube 31 is fixedly connected to a throat 32, and the output end of the throat 32 is fixedly connected to an expansion tube 33. A stabilizing sleeve plate 34 is sleeved on the side wall of both the shrink tube 31 and the expansion tube 33. Multiple spring shock absorbers 35 are installed on both stabilizing sleeve plates 34. A bent support rod 36 connected to multiple support rods 13 is installed on each of the multiple spring shock absorbers 35. A first connecting hose 37 is fixedly connected to the input end of the shrink tube 31, and the first connecting hose 37 is connected to the first connecting tube 26 through a flange. A second connecting hose 38 is fixedly connected to the output end of the expansion tube 33. Reference Figure 9 and Figure 10 The ultrasonic vibrating element 4 includes a mounting ring 41 coaxially mounted on the side wall of the throat tube 32. A fixing ring 42 is welded at the connection between the mounting ring 41 and the throat tube 32. A conductor ring 43 is coaxially sleeved on the mounting ring 41. An amplitude-changing ring 44 is coaxially sleeved on the conductor ring 43. Multiple ultrasonic transducers 45 are mounted on the amplitude-changing ring 44.

[0025] Reference Figure 9 and Figure 10The mechanical vibration component 5 includes a rotating ring 51 fixedly connected to the inner wall of the throat tube 32. The rotating ring 51 has a rotating groove 52 on its side wall. Multiple matching annular blocks 53 are provided in the rotating groove 52. A first connecting rod 54 is fixedly connected to the side wall of each of the multiple annular blocks 53. One end of the multiple first connecting rods 54 is fixedly connected to the same connecting seat 55. A first impeller 56 is installed on the side wall of the connecting seat 55. A first vertical rod 57 is fixedly connected to the lower end of the connecting seat 55. An eccentric block 58 is installed on the side wall of the first vertical rod 57. Reference Figure 10 and Figure 11 The heat sink 6 includes an annular groove 61 on the side wall of the throat 32. The annular groove 61 contains multiple first strong magnetic blocks 62 that can rotate along the groove opening. The upper end of the connecting seat 55 is fixedly connected to a second vertical rod 63. Multiple second connecting rods 64 connected to the first strong magnetic blocks 62 are fixedly connected to the side wall of the second vertical rod 63. A second impeller 65 is installed on the second vertical rod 63. A stabilizing sleeve 66 is coaxially sleeved on the outer side wall of the throat 32. The stabilizing sleeve 66 contains multiple second strong magnetic blocks 67 that match the first strong magnetic blocks 62. The side walls of the multiple second strong magnetic blocks 67 are fixedly connected to the same heat dissipation fan blade 68. Multiple heat sinks 69 are coaxially fixedly connected to the outer side wall of the throat 32.

[0026] More specifically, when liquid material enters the contraction tube 31 from the first connecting hose 37, the liquid impacts the first impeller 56 and the second impeller 65. When the liquid impacts the first impeller 56, it is limited by the annular block 53, the rotating groove 52 and the first connecting rod 54, causing the first impeller 56 to rotate. This causes the connecting seat 55 to rotate, which in turn causes the first vertical rod 57 to rotate, and further causes the eccentric block 58 to rotate. When the eccentric block 58 rotates, it generates a periodic unbalanced force, causing the throat tube 32 to generate high-frequency mechanical vibration. The vibration is superimposed on the high-speed shearing of the throat tube 32 itself, further breaking down and dispersing the droplets / particles. When the liquid impacts the second impeller 65, the second impeller 65 rotates. This rotation causes the second vertical rod 63 to rotate, which in turn causes the second connecting rod 64 to rotate. This, in turn, causes the first strong magnetic block 62 to rotate within the annular groove 61. Because the first and second strong magnetic blocks 62 and 67 are magnetically attracted, the rotation of the first strong magnetic block 62 causes the second strong magnetic block 67 to rotate, thereby causing the cooling fan blades 68 to rotate. This further accelerates the rotation of the area around the heat sink 69. The air circulation is good, and the heat sink 69 can absorb the heat on the throat 32, further reducing the heat generated by the high-speed flow of the liquid, thus ensuring the quality of the liquid material. At the same time, it is particularly noteworthy that the stabilizing sleeve 66 has little impact on the magnetic attraction of the first strong magnetic block 62 and the second strong magnetic block 67, and the stabilizing sleeve 66 can increase the strength of the throat 32, further ensuring the normal operation of the throat 32. At the same time, the stabilizing sleeve 66 can limit the second strong magnetic block 67, further preventing the second strong magnetic block 67 from detaching, thus ensuring the normal use of the device.

[0027] The stabilizing sleeve 34, spring damper 35, and bending support rod 36 can effectively support the contraction tube 31, throat tube 32, and expansion tube 33. At the same time, a rubber damping pad can be provided between the spring damper 35 and the stabilizing sleeve 34. The rubber pad is used for mid-to-high frequency attenuation (high frequency structural vibration caused by ultrasound), and the spring damper can be used for low frequency vibration / mechanical eccentric vibration, thus ensuring the overall stability of the device.

[0028] When the ultrasonic transducer 45 is working, the vibration generated by the ultrasonic transducer 45 can be directly transmitted to the conductor ring 43 and the mounting ring 41. This allows the liquid material to be subjected to ultrasonic vibration as it passes through, thereby further shearing and dispersing the material and improving the mixing and dispersion effect of the material.

[0029] Reference Figure 9 The flow guiding and mixing component 7 includes a spiral guide vane 71 installed on the side wall of the expansion tube 33, an impact plate 72 fixedly connected to the inner side wall of the expansion tube 33, a plurality of serrated through holes 73 provided on the impact plate 72, a partition plate 74 fixedly connected to the side wall of the expansion tube 33, a plurality of output heads 75 installed at the output end of the partition plate 74, and the output directions of the plurality of output heads 75 are staggered.

[0030] Reference Figure 12 and Figure 13The output component 8 includes an output cylinder 81 fixedly installed on the first bracket 12. The input end of the output cylinder 81 is fixedly connected to a second connecting pipe 82 connected to a second connecting hose 38 via a flange. Multiple second foot blocks 83 are fixedly connected to the inner bottom of the output cylinder 81. The upper ends of the multiple second foot blocks 83 are fixedly connected to the same overflow cylinder 84, and the overflow cylinder 84 is located directly below the second connecting pipe 82. A demister screen 85 is installed on the side wall of the overflow cylinder 84. Multiple overflow ports 86 are provided on the side wall of the overflow cylinder 84. An output pipe 87 is installed at the output end of the output cylinder 81. An exhaust pipe 88 for exhausting air is installed on the output cylinder 81.

[0031] Working principle: When material enters the feed pipe 24 through the external pump body, with the assistance of the guide plate 23, the liquid material can enter the input cylinder 21 tangentially, forming a strong swirling flow. The swirling liquid flows downward along the tank wall, bypasses the bottom of the vertical cylinder 253 at the bottom of the tank, and enters the interior of the vertical cylinder 253 from the outer ring. The liquid then flows upward back along the interior of the vertical cylinder 253, overflows from the top of the vertical cylinder 253, and is again guided tangentially into the outer ring. The reciprocating circulation between the inner and outer rings and the turbulence effect of the baffle plate 254 create a continuous three-dimensional circulation inside the tank, resulting in a strong stirring effect. It is particularly important to note that... The diameter of the output end of the input cylinder 21 is smaller than that of the vertical cylinder 253. The fluid coming from the bottom of the vertical cylinder 253 will first hit the baffle plate 254 and be thrown to the side, making it difficult to be directly sucked into the output end. The output end draws water from the side of the baffle plate 254, which is equivalent to taking a detour. At the same time, the arrangement of the collection seat 255 and the first connecting pipe 26 allows the liquid to flow to the area around the collection seat 255 at the bottom before going down. This increases the path and reduces the direct flow, thereby increasing the time for the liquid to flow in the input cylinder 21. This further increases the time for the liquid to be stirred and mixed in the input cylinder 21, thereby improving the mixing effect of the liquid.

[0032] When the liquid material enters the contraction tube 31 from the first connecting hose 37, the liquid impacts the first impeller 56 and the second impeller 65. When the liquid impacts the first impeller 56, it rotates due to the auxiliary limiting effect of the annular block 53, the rotating groove 52, and the first connecting rod 54. This causes the connecting seat 55 to rotate, which in turn causes the first vertical rod 57 to rotate, further causing the eccentric block 58 to rotate. When the eccentric block 58 rotates, it generates a periodic unbalanced force, causing the throat 32 to generate high-frequency mechanical vibration. This vibration, superimposed on the high-speed shearing of the throat 32 itself, further breaks down and disperses the droplets / particles. When the ultrasonic transducer 45 is working, the vibration generated by the ultrasonic transducer 45 can be directly transmitted to the conductor ring 43 and the mounting ring 41. This allows the liquid material to receive ultrasonic vibration as it passes through, further shearing and dispersing the material, thereby improving the mixing and dispersion of the material. The dispersion effect is achieved by high-speed shearing and turbulence rings creating fine eddies that break up droplet particles as the liquid flows through at high speed. Meanwhile, the first impeller 56 and eccentric block 58 generate periodic mechanical vibrations under pure fluid drive, causing localized strong vibrations in the throat section. The ultrasonic transducer 45 generates cavitation and micro-jet flow in the throat 32 region, further refining and dispersing the liquid. Simultaneously, when the second impeller 65 rotates, the second vertical rod 63 rotates, which in turn rotates the second connecting rod 64. This further causes the first strong magnetic block 62 to rotate within the annular groove 61. Due to the magnetic attraction between the first and second strong magnetic blocks 62 and 67, the rotation of the first strong magnetic block 62 causes the second strong magnetic block 67 to rotate, thereby rotating the cooling fan blades 68. This further accelerates airflow around the heat sink 69, which absorbs heat from the throat 32, further reducing the heat generated by the high-speed flow of the liquid and ensuring the quality of the liquid material. Then the liquid is output from the spiral guide vane 71. As the liquid flows along the height direction, it is forced to descend along the spiral path, forming a rotating and axial flow, which enhances mixing. The serrated through-hole 73 enables the liquid to form multiple fine jets. After the high-speed swirling jet hits the impact plate 72, the kinetic energy is converted into a radial jet and downward scouring. The serrated through-hole 73 then divides this jet into many small high-speed pulses, which greatly increases the near-field turbulence. This step is equivalent to the high-energy jet coming out of the throat 32 being broken into a high-speed drizzle, which quickly mixes with the liquid in the tank. It is particularly noteworthy that the output directions of the output head 75 are staggered, which allows the liquids to impact each other, further improving the mixing and dispersion effect.

[0033] Then the liquid will enter the second connecting pipe 82 from the second connecting hose 38, and then the liquid will enter the overflow cylinder 84. With the assistance of the demister 85, the foam generated by the liquid due to the impact can be eliminated. At the same time, the exhaust pipe 88 can discharge excess gas, and the liquid can be discharged from the overflow port 86, so that the treated liquid can be discharged more smoothly outside the device.
