Description
Technical Field
The utility model relates to a complete mixed flow high shear mixer can be used to the reinforcing and mix, dispersion and dissolve speed.
Background
The high-shear mixer is a novel process intensification device, and the core part of the high-shear mixing head is composed of a rotor (100-. The high end line speed of the rotor (10-50m/s) and the narrow shear gap (0.1-2mm) between the stator and the rotor determine that the rotor has a strong shear rate and a large local energy dissipation rate, which can effectively promote energy and mass transfer, and thus are widely used for strengthening mixing, dissolving, emulsifying, homogenizing, depolymerizing and reacting processes.
Mixing, dispersing and dissolving operations are widely present in industrial processes, and the efficiency and effectiveness thereof often have a significant impact on the design and operating costs of the process, the quality of the product and the overall benefits. For typical external force-operated mixing, dispersing and dissolving operations carried out in a mixing kettle, the effectiveness and efficiency depend on several aspects: 1) different materials have stronger movement capability under the action of mixing equipment, and no flowing dead zone exists in the mixing kettle; 2) the fluid material has a larger turbulence degree so as to ensure that certain shearing stress and turbulent kinetic energy dissipation rate exist in the fluid; 3) the solid particles are present in a well-dispersed state and are not stacked. 4) The mixing equipment has certain crushing capacity to solid materials. The fully-mixed flow high-shear mixer has the advantages of high linear speed of the tail end of the rotor, strong driving force to fluid, and strong local shear rate and turbulent kinetic energy dissipation rate; and the special stator and rotor configuration design can form controllable strong multidirectional jet flow during working, so that the dead zone of fluid flowing in the mixing kettle is eliminated, and the mixing kettle is more suitable for strengthening the traditional dissolving, dispersing and mixing operation.
In the published patents, various mixers have been used for mixing, dissolving and dispersing operations. Patent CN209034175U discloses a high shear emulsifying machine which combines a common stirring blade with high shear coaxially to improve the circulation and dispersion state of the material. Patent CN202366705U discloses a rapid flow type dispersing mixer with three-blade propeller rotor, which is matched with a stator with round holes and rectangular inclined holes on the side surface to enhance the circulation and dispersion capability of the material and improve the mixing effect. Patent CN205760694U discloses a high shear dispersion emulsifier equipped with a stator with rectangular openings and a rotor in various forms. Patent CN202398316U discloses a rapid-flow high-efficiency dispersing mixer with four blades, which is cooperated with a coaxial counter-rotating impeller to enhance the dispersing effect of powder and liquid materials.
The technology of the patent can achieve better strengthening effect when used for mixing, dispersing and dissolving operations, but the rotor of the high-shear mixer in the patent is a straight blade or a vertical blade, and the pore canal of the opening on the side wall of the stator has no inclination angle; therefore, the material is pushed by the rotor to be discharged from the bottom wall opening or the side wall opening of the stator in a jet mode, the two jets are vertical in direction, the fluid in the area between the two jets lacks enough pushing force, the flowing capacity is weak, a stagnation area is easy to form, and the mixing and dispersing effects are not ideal. On the other hand, some patents adopt a form of coaxial combination of a high-shear mixer and a stirring paddle, so that although the driving force of material flow can be properly enhanced, the circulation capacity of the material is improved; however, the shearing of the fluid and the bottom wall of the stator is lacked, and meanwhile, a dead zone of up-and-down flow on the outer side surface of the stator caused by low rotating speed exists, so that the shearing, crushing and mixing capabilities of high shearing on materials cannot be exerted, the rotating speed of the rotor can only be increased to strengthen shearing, crushing and mixing, and the power consumption is overhigh.
Therefore, in view of the above two aspects, in order to improve the flow driving force to the material and enhance the material circulation capacity; the high shearing effect of the interaction of the stator and the rotor is ensured, and the shearing and crushing capability of the material is improved; and the flow shape structure of the optimized fluid flow is also adjusted, and a stagnation zone or a dead zone formed by the fluid flow is eliminated, so that the design of the fully-mixed high-shear mixer meeting the requirements is urgently needed.
