Description

Technical Field

[0001] This application relates to the field of material dispersion technology, and in particular to a circulating dispersion device. Background Technology

[0002] Dispersion equipment is a mechanical device that uses physical action to uniformly disperse solid particles, liquids, or gases into another medium. Its core function is to achieve efficient mixing and homogenization of materials through physical processes. The dispersion effect of materials or slurries often affects the stability of precision processes, the consistency of product quality, and the functionality of the final product.

[0003] However, in existing dispersion equipment, when processing materials containing solid particles, the particles tend to settle to the bottom of the dispersion container due to the difference in density between the solid particles and the liquid. This affects the dispersion of the material; the material near the stirring blades disperses well, while the particles that have settled to the bottom are difficult to disperse, resulting in uneven dispersion or even poor dispersion effect.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0039] See Figure 1 and Figure 2 As shown in the figure, an embodiment of this application provides a circulating dispersion device, including: a stirring device 1, a dispersion device 2, a power device 3, and a circulating pipeline 4.

[0040] The mixing device 1 is equipped with a mixing mechanism 11 for mixing the slurry. The mixing device 1 plays a basic mixing role in the slurry processing. Through mechanical mixing, it generates shear force and turbulence to initially mix the slurry. It can break up larger particles in the slurry and break the tendency of particles to settle, thereby reducing the possibility of slurry stratification to a certain extent and achieving initial dispersion of the slurry.

[0041] Dispersing device 2 is used to disperse slurry.

[0042] In an optional embodiment, the dispersion device 2 is provided with an ultrasonic component 21, which can generate a cavitation effect by utilizing the high-frequency vibration of ultrasonic waves, causing microbubbles to rupture under the action of ultrasonic waves, forming instantaneous high pressure and microjets, effectively breaking up nanoscale agglomerates.

[0043] In an optional embodiment, the ultrasonic component 21 uses an ultrasonic frequency of 20-40 kHz. Within this frequency range, the generation efficiency of the cavitation effect and the energy consumption requirements of the equipment can be better balanced, thereby ensuring the crushing effect while maintaining the stable operation of the system.

[0044] The dispersing device 2 and the stirring device 1 work together to achieve progressive particle refinement in the slurry. Specifically, the stirring device 1, as the primary processing unit, initially crushes and disperses the particles in the slurry, improving the particle agglomeration state to a certain extent. The dispersing device 2, as the secondary processing unit, further refines the slurry processed by the stirring device 1, reducing the particle size to a smaller level. This progressive refinement method allows for more precise control of the particle refinement degree, effectively avoiding problems such as insufficient or excessive particle refinement that may occur with a single processing method. It improves the uniformity of particle distribution in the slurry, thereby enhancing the overall quality and performance stability of the slurry.

[0045] The power unit 3 is used to provide power for the flow of slurry. In some embodiments of this application, the power unit 3 may include a centrifugal pump or a screw pump. The centrifugal pump or screw pump has a stable conveying capacity, which can ensure the continuous flow of slurry between the mixing device 1 and the dispersing device 2, effectively improving the continuity and efficiency of slurry processing.

[0046] Of course, the above content is only some examples of the power unit 3, and does not limit the specific implementation structure of the power unit 3.

[0047] The circulation pipe 4 is connected to the stirring device 1, the dispersing device 2, and the power device 3, respectively. A valve 41 is installed between any two of the stirring device 1, the dispersing device 2, and the power device 3; that is, valves 41 are installed on the connecting pipe sections of the stirring device 1 and the dispersing device 2, the stirring device 1 and the power device 3, and the dispersing device 2 and the power device 3. By controlling the opening and closing of the valves 41, a first slurry circulation loop can be formed between the stirring device 1 and the power device 3, and / or a second slurry circulation loop can be formed between the dispersing device 2 and the power device 3.

[0048] The first slurry circulation loop involves the slurry starting from the mixing device 1, being driven by the power unit 3, and returning to the closed circulation loop of the mixing device 1 via the circulation pipe 4. The second slurry circulation loop involves the slurry flowing out from the power unit 3, being driven by the power unit 3, being transported to the dispersing device 2 via the circulation pipe 4, being processed by the dispersing device 2, and then flowing back to the closed circulation loop of the power unit 3 via the circulation pipe 4.

[0049] Of course, the above content is only an example of the first slurry circulation loop and the second slurry circulation loop, and does not impose any restrictions on the specific settings of the slurry circulation loop.

[0050] Specifically, when the two valves 41 between the dispersing device 2 and the power device 3 are closed, and the two valves 41 between the stirring device 1 and the power device 3 are opened, the first slurry circulation loop is opened; when the two valves 41 between the stirring device 1 and the power device 3 are closed, and the two valves 41 between the dispersing device 2 and the power device 3 are opened, the second slurry circulation loop is opened.

[0051] Through the cooperation of the circulation pipe 4 and valve 41, the opening, closing, and switching of the first and / or second slurry circulation loops can be realized. The first slurry circulation loop, composed of the stirring device 1 and the power device 3, effectively promotes the thorough mixing of the components in the slurry, prevents particle sedimentation, and performs preliminary crushing of any large particles present in the slurry. The second slurry circulation loop, composed of the dispersing device 2 and the power device 3, further refines the particle size and improves the dispersion uniformity of the slurry. For example, when processing high-viscosity slurries, the first slurry circulation loop can be activated first, utilizing its mixing and anti-settling functions to complete the basic mixing and wetting process of the slurry. Then, the process can be switched to the second slurry circulation loop, using ultrasonic waves for fine dispersion to further refine the slurry particles, thereby meeting the performance requirements of the slurry at different process stages.

[0052] For another example, if there are still many large particles in the slurry after being processed by the stirring device 1, the large particles in the slurry can be processed multiple times through the first slurry circulation loop until the size of the particles reaches the preset target, and then the second slurry circulation loop is opened to achieve fine dispersion processing of the slurry.

[0053] In an optional embodiment, such as Figure 1 As shown, the stirring device 1 includes an inner cavity 12 and an outer cavity 13.

[0054] A cooling layer 14 is formed between the inner cavity 12 and the outer cavity 13. The outer cavity 13 is provided with an inlet 131 and an outlet 132 that communicate with the cooling layer 14.

[0055] The cooling layer 14 is used to contain coolant, such as water or an ethylene glycol solution. During operation, the coolant enters the cooling layer 14 through the inlet 131 and flows out through the outlet 132, forming a circulating cooling loop. During this process, the coolant is in direct contact with the wall of the inner cavity 12, carrying away the heat generated in the inner cavity 12 through heat exchange, thereby maintaining a stable temperature in the inner cavity 12. This effectively controls the ambient temperature during slurry mixing, preventing slurry decomposition or performance changes due to localized overheating, and ensuring the stability of the mixing process and the quality of the slurry.

[0056] In some embodiments of this application, the liquid inlet 131 and liquid outlet 132 on the outer cavity 13 are located at the top and bottom of the cooling layer 14, respectively, forming a forward convection cooling circuit. In other embodiments of this application, the liquid inlet 131 and liquid outlet 132 on the outer cavity 13 are located at the bottom and top of the cooling layer 14, respectively, forming a reverse convection cooling circuit. The liquid inlet 131 is connected to an external coolant supply device, and the liquid outlet 132 is connected to a recycling system, forming a closed-loop cooling cycle.

[0057] In some embodiments of this application, the cooling layer 14 is a double-walled jacket structure, with its inner wall tightly fitted to the outer wall of the inner cavity 12, and the outer wall forming the inner sidewall of the outer cavity 13. The inner wall surface of the cooling layer 14 adopts a spiral or wave-like structure design to guide the coolant to form a spiral or wave flow, thereby enhancing the convective heat transfer effect.

[0058] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the circulating dispersion equipment is also equipped with a cooling device 5, which is connected to the power device 3, the dispersion device 2 and the stirring device 1 respectively.

[0059] Understandably, the cooling device 5 can cool the slurry, effectively control the slurry temperature, and to a certain extent avoid changes in the slurry properties due to excessively high temperatures during stirring or dispersion, such as excessively high viscosity or uneven composition, thereby ensuring product quality. Moreover, the cooled slurry can maintain a lower viscosity, reducing the problem of decreased working efficiency of the device due to overheating, improving the smoothness of the dispersion and stirring process, and reducing energy consumption. The cooling device 5 can also keep the slurry within a stable temperature range throughout the entire processing, which helps to maintain the consistency of the process and improve the stability and controllability of the production process.

[0060] In an optional embodiment, such as Figure 3 As shown, the cooling device 5 includes a cooling container 51 and a cooling pipe 52.

[0061] The cooling container 51 is used to contain the coolant, and the cooling pipe 52 is wound in the cooling container 51 and connected to the power unit 3, the dispersing device 2 and the stirring device 1 to cool the slurry.

[0062] The cooling pipe 52 is wound and arranged in the cooling container 51, which can increase the contact area with the coolant, improve the heat exchange efficiency, and reduce the temperature of the slurry more quickly. By effectively cooling the slurry, its stable physical properties can be maintained, preventing changes in slurry performance caused by excessive temperature. The cooling effect of the slurry can be precisely controlled to maintain the stability of the process.

[0063] The coolant can be water or ethylene glycol.

[0064] In an optional embodiment, such as Figure 4 As shown, the stirring mechanism 11 includes a motor 111, a stirring shaft 112, and multiple stirring components 113.

[0065] Multiple agitators 113 are arranged at one end of the agitator shaft 112 and are evenly distributed along the axial direction of the agitator shaft 112. The other end of the agitator shaft 112 is connected to the output end of the motor 111. The motor 111 is used to drive the agitator shaft 112 to rotate, thereby driving the multiple agitators 113 to rotate, so as to achieve agitation of the slurry.

[0066] Understandably, by distributing multiple agitators 113 along the axial direction, forces can be applied to the slurry more evenly during the mixing process, ensuring that the forces acting on different parts of the slurry within the mixing space are consistent. This contributes to the uniform distribution of the slurry and lays the foundation for better dispersion. Simultaneously, the presence of multiple agitators 113 divides the mixing space into multiple mixing zones. Each mixing zone can independently and efficiently mix the slurry, and the mixing effects between different zones synergistically accelerate the mixing process, effectively shortening the mixing time and improving overall production efficiency. Furthermore, the rotation of multiple agitators 113 disturbs the slurry, disrupting the settling tendency of particles and preventing particle settling to a certain extent. This maintains the stability and uniformity of the slurry, ensuring the smooth progress of subsequent processes.

[0067] In an optional embodiment, each agitator 113 includes a plurality of agitator blades 1311, which are uniformly arranged circumferentially along the agitator shaft 112.

[0068] Understandably, evenly distributing multiple stirring blades 1311 around the circumference of the stirring shaft 112 helps ensure uniform mixing of the slurry during the mixing process. Each stirring blade 1311 contacts different parts of the slurry, resulting in more uniform mixing and improved mixing efficiency. The distribution of multiple stirring blades 1311 around the circumference of the stirring shaft 112 allows them to act on multiple areas simultaneously, effectively increasing the surface area used for stirring the slurry, thereby accelerating the mixing process and improving work efficiency. The evenly distributed stirring blades 1311 also effectively avoid dead zones or blind spots during mixing, i.e., areas that the stirring element 113 cannot reach. Furthermore, the evenly distributed circumferential stirring blades 1311 can create a multi-directional flow field, breaking up liquid stratification. Multiple stirring blades 1311 push the slurry from different angles, causing the slurry to be evenly dispersed in both vertical and horizontal directions.

[0069] In an optional embodiment, such as Figure 1 As shown, a filter structure 15 is also provided at the connection between the stirring device 1 and the power device 3 and / or the dispersing device 2.

[0070] Specifically, in some embodiments of this application, the filter structure 15 is mesh-like. Of course, there is no limitation on the specific shape of the filter structure 15.

[0071] Understandably, the filter structure 15 effectively filters impurities or larger particles in the slurry, improving the purity of the slurry, which helps to improve mixing and dispersion, and ultimately enhances the final quality of the slurry. The interception of impurities by the filter structure 15 also helps reduce wear on the equipment, thus extending its service life.

[0072] In an optional embodiment, such as Figure 5 As shown, the ultrasonic component 21 includes an ultrasonic head 211, an amplitude modulator 212, and a transducer 213. The transducer 213 is connected to the amplitude modulator 212, and the amplitude modulator 212 is connected to the ultrasonic head 211. The ultrasonic head 211 is located inside the dispersion device 2 to perform ultrasonic vibration on the slurry entering the dispersion device 2.

[0073] The ultrasonic head 211 is the main component of the ultrasonic assembly 21, responsible for converting the ultrasonic energy generated by the transducer 213 into mechanical vibration and transmitting this vibration to the slurry, directly affecting the dispersion of particles or substances in the slurry. The amplitude modulator 212 is mainly used to control the amplitude of the ultrasonic head 211, making the ultrasonic energy output more stable and adjustable. The amplitude modulator 212 controls the amplitude of the ultrasonic wave by adjusting the current input. The transducer 213 is responsible for converting electrical energy into mechanical vibration, directly affecting the vibration frequency and power output of the ultrasonic wave.

[0074] The ultrasonic component 21 enables the circulating dispersion equipment to more uniformly disperse particles or substances in the slurry through ultrasonic vibration, preventing particle aggregation and sedimentation, thereby improving the stability and uniformity of the slurry. Ultrasonic dispersion can also accelerate the slurry processing, significantly reduce processing time, and improve production efficiency.

[0075] In an optional embodiment, such as Figure 1 As shown, the stirring device 1 is provided with a feed inlet 121 and a discharge outlet 122. A flow sensing mechanism (not shown in the figure) and an electric valve 123 are respectively provided at the feed inlet 121 and the discharge outlet 122.

[0076] Specifically, in some embodiments of this application, the flow sensing mechanism may be a flow meter, and the type of flow meter may be any one or more combinations of vortex flow meter, electromagnetic flow meter, ultrasonic flow meter or turbine flow meter.

[0077] Understandably, the flow sensor mechanism enables real-time flow monitoring, helping the slurry enter or leave the mixing device 1 at a predetermined rate. This avoids problems such as uneven mixing and insufficient blending caused by flow fluctuations, thereby ensuring efficient operation of the mixing process and the stability of the final product quality. The flow sensor mechanism and the electric valve 123 work together to form an intelligent flow control system. Based on the real-time flow information fed back by the flow sensor mechanism, the electric valve 123 can automatically adjust its opening to achieve precise regulation of the slurry flow, reducing the possibility of excessive or insufficient flow during feeding or discharging, and improving the automation level and operational reliability of the circulating dispersion equipment.

[0078] Furthermore, such as Figure 2 As shown, the side wall of the stirring device 1 is also provided with a visible liquid level window 16.

[0079] The level window 16 allows operators to observe the slurry level inside the mixing device 1 in real time, preventing the mixing effect from being affected or the equipment from malfunctioning due to excessively high or low liquid levels. Through the level window 16, operators can make real-time adjustments based on observed changes in the liquid level, which can, to some extent, prevent overflow caused by excessively high liquid levels or affect the normal operation of the mixing device 1 due to excessively low liquid levels, thus maintaining the stability of the production process.

[0080] The embodiments of this application have at least the following beneficial effects:

[0081] This application provides a circulating dispersion device that enhances control over the slurry dispersion step and significantly improves the uniformity of slurry dispersion. Specifically, the stirring device 1 can stir the slurry and perform preliminary treatment on the coarse particles of the slurry; the dispersion device 2 can disperse the slurry using ultrasonic waves, further reducing the particle size of the slurry; and through the control of the circulation pipe 4 and valve 41, the stirring device 1 and / or the dispersion device 2 can perform multiple cycles of stirring and dispersion of the slurry, reducing the possibility of uneven slurry dispersion; and by controlling the first slurry circulation loop and / or the second slurry circulation loop, one or a combination of the stirring device 1 and the dispersion device 2 can be used to specifically improve the dispersion state of the slurry.

[0083] Those skilled in the art will understand that the modules in the apparatus of the implementation scenario can be distributed within the apparatus of the implementation scenario as described, or they can be located in one or more apparatuses different from this implementation scenario, with corresponding changes.
