Description

Technical Field

[0001] This invention relates to the field of stirring technology, specifically to a high-speed dispersion stirring device and control method. Background Technology

[0002] In the mixing and foaming process of gas-liquid-solid multiphase systems, achieving efficient, uniform, and stable stirring is a key step in obtaining high-quality homogeneous products. In existing technologies, conventional mechanical stirring devices are usually driven by ordinary motors, with their output shafts directly connected to the stirring shaft to drive the stirring paddle to rotate, thereby applying shearing and mixing effects to the multiphase mixture.

[0003] However, limited by the performance bottlenecks of traditional motors, such stirring systems often struggle to provide sufficiently high rotational speeds, resulting in low shear rates during stirring and failing to effectively meet the requirements of multiphase systems for high-intensity, high-uniformity mixing. Specifically, the flow field intensity generated by existing stirring devices is insufficient and spatially uneven, making it difficult to construct effective shear zones with multiple angles and high intensity within the stirring chamber. This not only easily creates flow "dead zones" in container corners or impeller blind areas but also significantly weakens the dispersion efficiency of the gas-liquid two phases, causing problems such as large bubble aggregation, wide bubble size distribution, and liquid phase stratification.

[0004] The aforementioned defects are particularly prominent in complex multiphase systems containing solid particles. Due to insufficient and unevenly distributed shear force in the flow field, solid particles in the system are prone to sedimentation or agglomeration, making it difficult to achieve uniform suspension. This, in turn, severely affects the overall homogeneity, microstructural consistency, and long-term physical stability of the mixture.

[0005] Therefore, it is necessary to provide a high-speed dispersion and stirring device and control method to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide a high-speed dispersion and stirring device and control method to solve the problems mentioned in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a high-speed dispersion and stirring device and control method, including a mounting frame, a high-speed motor mounted at the front end of the mounting frame, an electromagnetic stirrer mounted in the mounting frame and coaxially mounted with the output end of the high-speed motor, and a dispersion and stirring mechanism mounted at the rear end of the mounting frame.

[0008] The dispersion and stirring mechanism includes a stirring outer shell installed at the tail end of the mounting frame, a stirring chamber disposed within the stirring outer shell, and a pressure injection component installed at the tail end of the stirring outer shell.

[0009] The stirring shell is provided with a gas-liquid inlet communicating with the stirring chamber. The stirring chamber is filled with a gas-liquid mixture. The stirring end of the electromagnetic stirrer extends into the stirring chamber. The stirring end of the electromagnetic stirrer is provided with a dispersion component. The dispersion component includes: a mounting base installed on the stirring end of the electromagnetic stirrer and two dispersion discs symmetrically installed on the mounting base.

[0010] The electromagnetic stirrer controls the rotation of the dispersion component, breaking the gas-liquid mixture into a uniform foam.

[0011] Furthermore, the dispersion disk is provided with a plurality of liquid through holes for the flow of the gas-liquid mixture.

[0012] Furthermore, the pressure injection assembly includes: a tail end plug disposed at the tail end of the stirring housing, an installation channel penetrating within the tail end plug, a pressure loading pump installed at the tail end of the installation channel, and a piston installed within the stirring chamber; the plunger end of the pressure loading pump is installed with the piston through the installation channel.

[0013] Furthermore, the piston is provided with a mounting groove, and a first threaded ring for mounting the plunger end of the pressure loading pump is provided in the mounting groove.

[0014] Furthermore, the end of the mounting channel is provided with a second threaded ring for mounting in conjunction with the plunger end of the pressure loading pump.

[0015] Furthermore, the gas-liquid inlet is externally threaded with a multi-way directional valve for multi-functional switching.

[0016] Furthermore, the electromagnetic stirrer includes: a mounting housing installed in the mounting frame, an electromagnet assembly installed in the mounting housing, and a stirring shaft installed on the electromagnet assembly, the stirring shaft extending into the stirring chamber, and the dispersing component installed at the end of the stirring shaft.

[0017] Furthermore, a head end plug is provided between the electromagnetic stirrer and the dispersion stirring mechanism. One end of the head end plug is located at the head end of the stirring shell, and the other end is located inside the mounting shell.

[0018] Furthermore, the mounting frame includes: a first mounting plate, a second mounting plate, and a plurality of support columns disposed between the first mounting plate and the second mounting plate; the high-speed motor is mounted on the outside of the first mounting plate, and the electromagnetic stirrer is mounted on the inside of the second mounting plate.

[0019] Furthermore, the control method of the high-speed dispersion and stirring device

[0020] S1. Inject the gas and liquid into the stirring chamber through the gas-liquid inlet, respectively;

[0021] S2. Start the high-speed motor and control the electromagnetic stirrer to stir the gas-liquid mixture in the stirring chamber at high speed, so that the gas-liquid mixture is transformed into a foamy state;

[0022] S3. Start the pressure loading pump to push the piston from the tail end to the head end in the stirring chamber, and push the foamy gas-liquid mixture out of the gas-liquid inlet.

[0023] The beneficial effects of the present invention are as follows: The present invention provides a high-speed dispersion and stirring device and control method. The device achieves rapid and uniform foaming treatment of gas-liquid mixtures through the precise coordination of a high-speed motor and an electromagnetic stirrer. With the assistance of the dispersion component, the gas-liquid mixture can be sheared, stretched and converted into a fine and uniform foam system, avoiding the formation of flow "dead zones" in container corners or blade blind areas, and significantly reducing the dispersion efficiency of the gas-liquid two phases, resulting in the aggregation of large bubbles.

[0024] This device effectively eliminates dead zones during stirring, ensuring thorough mixing of gas and liquid, and stably attaching suspended solid particles to the foam network. This improves the uniformity and dynamic stability of the final product. The liquid through-holes on the dispersion disc not only reduce flow resistance but also enhance dispersion, allowing the gas to be cut more finely and evenly. This strengthens the interaction between gas and liquid, thereby improving the compactness and stability of foam formation. It avoids situations where insufficient shear force and uneven distribution in the flow field lead to sedimentation or agglomeration of solid particles in the system, making it difficult to achieve uniform suspension and severely affecting the overall homogeneity, microstructure consistency, and long-term physical stability of the mixture.

[0025] The presence of both end plugs ensures a high degree of sealing of the mixing chamber during high-speed mixing, preventing leakage of the gas-liquid mixture or infiltration of external contaminants, thus improving the uniformity of material mixing and the safety of equipment operation.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0045] like Figure 1-7 As shown, the present invention provides a technical solution: a high-speed dispersion and stirring device and a control method, as described in the reference. Figure 1 As shown, one end of the high-speed motor 2 is designated as the starting end.

[0046] refer to Figure 1-6 The present invention provides a high-speed dispersion and stirring device, comprising: a mounting frame 1, a high-speed motor 2 mounted at the front end of the mounting frame 1, an electromagnetic stirrer 3 mounted inside the mounting frame 1 and coaxially mounted with the output end of the high-speed motor 2, and a dispersion and stirring mechanism 4 mounted at the rear end of the mounting frame 1.

[0047] The dispersion and mixing mechanism 4 includes: a mixing shell 41 installed at the tail end of the mounting frame 1, a mixing chamber 42 disposed inside the mixing shell 41, and a pressure injection assembly 43 installed at the tail end of the mixing shell 41.

[0048] The outer casing 41 of the stirring device is provided with a gas-liquid inlet 5 that communicates with the stirring chamber 42. The stirring chamber 42 is filled with a gas-liquid mixture. The stirring end of the electromagnetic stirrer 3 extends into the stirring chamber 42. The stirring end of the electromagnetic stirrer 3 is provided with a dispersion component 6. The dispersion component 6 includes: a mounting base 61 installed on the stirring end of the electromagnetic stirrer 3 and two dispersion discs 62 symmetrically installed on the mounting base 61. The electromagnetic stirrer 3 controls the dispersion component 6 to rotate, thereby dispersing the gas-liquid mixture into a uniform foam.

[0049] In this embodiment, a high-speed motor 2 controls an electromagnetic stirrer 3 to perform high-speed stirring of the gas-liquid mixture in the stirring chamber 42, achieving rapid and uniform foaming of the gas-liquid mixture. Specifically, the high-speed motor 2 has the characteristic of high-speed drive. When the high-speed motor 2 drives the stirring shaft 33 of the electromagnetic stirrer 3 to rotate, the two symmetrically installed dispersion discs 62 rotate synchronously at high speed, performing rapid shearing and stretching of the gas-liquid mixture from multiple angles, forming a violent full-range circulation from the axial to the radial direction. This effectively eliminates the stirring dead zone, allowing the gas and liquid to be fully mixed during high-speed stirring and generating a large amount of foam. The solid particles in the liquid can float uniformly. At this time, the foam generated is gradually broken up and refined by the continuous cutting of the dispersion discs 62, forming a uniform foam system with a size reaching the nanometer level. This further enhances the uniformity and stability of the gas-liquid mixture, achieving a uniform and stable output of the gas-liquid mixture.

[0050] In this embodiment, the high-speed motor 2 and the electromagnetic stirrer 3 work in precise coordination to drive the dispersion component 6 to rotate with the stirring shaft 33, shearing the gas-liquid mixture in the stirring chamber 42 at multiple angles and levels to achieve initial homogeneous fusion. As the rotation speed of the stirring shaft 33 continues to increase, the dispersion disk 62 enters a high-speed rotation state, further agitating, stretching and breaking up the gas-liquid mixture, gradually transforming it into a fine and uniform foam system. During this process, the solid particles suspended in the liquid are completely wrapped and stably attached to the foam network, improving the uniformity and dynamic stability of the gas-liquid mixture, and finally forming a highly homogeneous and structurally stable multiphase mixture.

[0051] Furthermore, the dispersion disk 62 is provided with several liquid through holes 63 for the flow of the gas-liquid mixture. When the stirring shaft 33 drives the symmetrical dispersion disk 62 to rotate, the dispersion disk 62 applies multi-angle shearing forces to the gas-liquid mixture, forming stable stirring and circulation. However, the fluid resistance generated during stirring will restrict the mixing efficiency. By setting the liquid through holes 63, the flow resistance can be effectively reduced, allowing the gas-liquid mixture to flow smoothly through the channels. This not only reduces power loss but also strengthens the dispersion effect. Furthermore, it further promotes the gas to be cut into finer and more uniform bubbles and enhances the interaction force between gas and liquid, thereby improving the compactness and stability of foam formation.

[0052] like Figure 2 , Figure 5 and Figure 6 As shown, the pressure injection assembly 43 includes: a tail end plug 431 plugged at the tail end of the stirring shell 41, an installation channel 432 penetrating the tail end plug 431, a pressure loading pump installed at the tail end of the installation channel 432, and a piston 433 installed in the stirring chamber 42.

[0053] The plunger end of the pressure loading pump is installed with the piston 433 through the installation channel 432.

[0054] Furthermore, the piston 433 is provided with a mounting groove 434, and a first threaded ring 435 for mounting the plunger end of the pressure loading pump is provided in the mounting groove 434.

[0055] Furthermore, the end of the mounting channel 432 is provided with a second threaded ring 436 for mounting to mate with the plunger end of the pressure loading pump.

[0056] In this embodiment, piston 433 is disposed inside stirring chamber 42, and its diameter is the same as the inner diameter of stirring chamber 42. The plunger end of the pressure loading pump is inserted into the mounting channel 432, and the plunger end of the pressure loading pump is screwed tightly into the mounting channel 432 using the first threaded ring 435. Continuous screwing causes the plunger end to be inserted into the mounting groove 434 and tightly screwed into the second threaded ring 436, thus securing the plunger end of the pressure loading pump to the piston 433. When a gas-liquid mixture needs to be output, the pressure loading pump is activated, pushing piston 433 from the tail end to the head end of stirring chamber 42. This continuously pushes the uniformly foamed gas-liquid mixture from the gas-liquid outlet 5, achieving a stable and homogeneous output effect, effectively avoiding stratification or intermittent flow, and improving the consistency of fluid delivery.

[0057] Furthermore, the gas-liquid inlet 5 has an inlet 51 and an outlet 52. A multi-way directional valve for multi-functional switching is installed on the external thread of the inlet 51. Both gas and liquid flow into the mixing chamber 42 through the outlet 52 via the inlet 51 of the gas-liquid inlet 5. Under high-speed stirring, they rapidly merge and transform into a foamy state. After stirring, the fine and dense foamy gas-liquid mixture is still smoothly output through the gas-liquid inlet 5, through the outlet 52, back to the inlet 51. In addition, the multi-way directional valve ensures the coordination of multi-functional operation of the gas-liquid inlet 5's inlet 51, precisely guiding the output and input, achieving seamless switching and compact coordination of multi-functional operation of the gas-liquid inlet 5, further simplifying the pipeline layout, improving the continuity of equipment operation, and achieving efficient and stable integration of output and input.

[0058] like Figure 2 and Figure 4 As shown, the electromagnetic stirrer 3 includes: a mounting housing 31 installed in the mounting frame 1, an electromagnet assembly 32 installed in the mounting housing 31, and a stirring shaft 33 installed on the electromagnet assembly 32. The stirring shaft 33 extends into the stirring chamber 42, and the dispersing assembly 6 is installed at the end of the stirring shaft 33.

[0059] In this embodiment, the high-speed motor 2 provides continuous high-speed power to the electromagnet assembly 32, enabling the electromagnet assembly 32 to control the high-speed rotation of the stirring shaft 33, which in turn drives the dispersion assembly 6, mounted at the end of the stirring shaft 33, to rotate synchronously at high speed, thereby achieving high-speed stirring of the gas-liquid mixture. The electromagnet assembly 32 has high transmission efficiency and a high upper speed limit, and a fast response speed, ensuring that the power from the high-speed motor 2 is transmitted to the stirring shaft 33 with low delay and low loss, ensuring that the dispersion assembly 6 receives high-speed rotational power. Furthermore, the electromagnet assembly 32 adopts contactless control, reducing vibration and wear during high-speed rotation, making the operation more stable and reliable. At the same time, the speed of the electromagnet assembly 32 can be further adjusted, ensuring the stability of high-speed stirring through its cooperation with the high-speed motor 2.

[0060] like Figure 2 and Figure 4 As shown, a head end plug 7 is provided between the electromagnetic stirrer 3 and the dispersion stirring mechanism 4. One end of the head end plug 7 is plugged at the head end of the stirring shell 41, and the other end is located inside the mounting shell 31.

[0061] In this embodiment, the first end of the stirring chamber 42 is connected via an electromagnetic stirrer 3 and a first end plug 7. The plug has a precision channel inside for the stirring shaft 33 to pass through. The first end plug 7 and the last end plug 431 together form a sealing barrier, ensuring that the stirring chamber 42 remains highly sealed during high-speed stirring, effectively preventing leakage of the gas-liquid mixture or infiltration of external contaminants. This not only improves the uniformity and stability of material stirring but also enhances the safety of equipment operation, while reducing material loss and maintenance frequency.

[0062] like Figure 3 As shown, the mounting frame 1 includes: a first mounting plate 11, a second mounting plate 12, and a plurality of support columns 13 disposed between the first mounting plate 11 and the second mounting plate 12; a high-speed motor 2 is mounted on the outside of the first mounting plate 11, and an electromagnetic stirrer 3 is mounted on the inside of the second mounting plate 12.

[0063] In this embodiment, the high-speed motor 2 is mounted on the outside of the first mounting plate 11. The first mounting plate 11 has a first through hole, through which the output shaft of the high-speed motor 2 passes and is installed with the electromagnetic stirrer 3, continuously providing power to the electromagnetic stirrer 3. A second through hole is opened at the center of the second mounting plate 12, through which the stirring shaft 33 passes and extends into the stirring chamber 42 for uniform stirring. To ensure the sealing of the stirring chamber 42, the end plug 7 passes through the second through hole and is placed inside the stirring outer shell 41, effectively filling and sealing the gap between the stirring chamber 42 and the electromagnetic stirrer 3, eliminating the risk of leakage. The cooperation between the second mounting plate 12 and the end plug 7 not only provides reliable support for the stirring shaft 33, but also enhances the structural stability of the electromagnetic stirrer 3 during high-speed operation, improving stirring efficiency and the overall lifespan of the equipment.

[0064] like Figures 1-6 As shown, the present invention also provides a control method for a high-speed dispersion and stirring device, comprising the following steps:

[0065] S1. Inject the gas and liquid into the stirring chamber 42 through the gas-liquid inlet 5 respectively.

[0066] S2. Start the high-speed motor 2 and control the electromagnetic stirrer 3 to stir the gas-liquid mixture in the stirring chamber 42 at high speed, so that the gas-liquid mixture is transformed into a foam.

[0067] S3. Start the pressure loading pump, push the piston 433 to move from the tail end to the head end in the stirring chamber 42, and push the foamy gas-liquid mixture out of the gas-liquid inlet 5.

[0068] The control method for the high-speed dispersion and stirring device is as follows:

[0069] First, a certain proportion of gas and liquid are injected into the stirring chamber 42 through the gas-liquid inlet 5, respectively. The orderly input of gas and liquid is achieved by adjusting the direction of the multi-way reversing valve. Then, the stirring operation of gas and liquid begins: the high-speed motor 2 is started to continuously supply power to the electromagnetic stirrer 3. Under the action of the high-speed motor 2, the stirring shaft 33 of the electromagnetic stirrer 3 gradually rotates at high speed, causing the two symmetrical dispersion disks 62 installed at the end of the stirring shaft 33 to rotate at high speed, and performing multi-angle and multi-directional shearing and stirring of the gas-liquid mixture in the stirring chamber 42. During continuous high-speed shearing and stirring, the gas-liquid mixture gradually disperses and merges into a high-density foam, and the solid particles float uniformly in the foam network, at which point the stirring is completed.

[0070] After the mixing operation is completed, the output of the mixed gas-liquid mixture begins: the pressure loading pump is started, pushing piston 433 from the tail end to the head end of the mixing chamber 42, pushing the foamy gas-liquid mixture out of the gas-liquid inlet 5. Piston 433 is continuously pushed to ensure a continuous and stable output of the foamy gas-liquid mixture. During this output process, the high-speed motor 2 can be controlled to rotate continuously, keeping the gas-liquid mixture in the mixing chamber 42 in a foamy state. The high-speed motor 2 is stopped after the output is completed; alternatively, the high-speed motor 2 can be stopped first, and the foamy state of the output gas-liquid mixture can be maintained by rapidly pushing piston 433.

[0071] In summary, this device achieves rapid and uniform foaming of gas-liquid mixtures through the precise coordination of high-speed motor 2 and electromagnetic stirrer 3. With the assistance of dispersion component 6, the gas-liquid mixture can be sheared, stretched and converted into a fine and uniform foam system, avoiding the formation of flow "dead zones" in container corners or blade blind areas, and significantly reducing the dispersion efficiency of the gas-liquid two phases, resulting in the aggregation of large bubbles.

[0072] This device effectively eliminates dead zones during stirring, ensuring thorough mixing of gas and liquid, and stably attaching suspended solid particles to the foam network. This improves the uniformity and dynamic stability of the final product. The liquid through-holes 63 on the dispersion disk 62 not only reduce flow resistance but also enhance dispersion, allowing the gas to be cut more finely and evenly. This strengthens the interaction between gas and liquid, thereby improving the compactness and stability of foam formation. It avoids situations where insufficient shear force and uneven distribution in the flow field lead to sedimentation or agglomeration of solid particles in the system, making it difficult to achieve uniform suspension and severely affecting the overall homogeneity, microstructure consistency, and long-term physical stability of the mixture.

[0073] The presence of a front end plug 7 and a rear end plug 431 ensures a high degree of sealing of the mixing chamber 42 during high-speed mixing, preventing leakage of the gas-liquid mixture or infiltration of external pollutants, thereby improving the uniformity of material mixing and the safety of equipment operation.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
