Abstract
Description
Technical Field
[0001] This utility model belongs to the field of homogenizer technology, specifically a high-speed powder homogenizer with multiple oil injection units. Background Technology
[0002] High-speed powder homogenizers are highly efficient mixing equipment widely used in the food, chemical, pharmaceutical, and cosmetic industries. They are primarily used to achieve rapid and uniform mixing, dispersion, and homogenization of powders and liquids. With the increasing demands for product uniformity, stability, and process efficiency in modern industry, high-speed powder homogenization technology has become a key process in fine chemicals and new material preparation. This equipment uses high-speed rotating stirring components to generate strong shearing, impact, and turbulence, effectively breaking up particle agglomerations and promoting full contact between different components, thereby obtaining a mixed system with uniform particle size distribution and high stability. In the food industry, this technology can be used for homogenization of sauces, dairy products, and condiments; in the pharmaceutical field, it is suitable for the preparation of suspensions, creams, and other formulations; and in the new energy materials industry, it is widely used in the dispersion process of high-performance materials such as lithium battery electrode slurries and nanocomposite materials. With the development of intelligent manufacturing and green processes, high-speed powder homogenization technology is continuously evolving towards higher efficiency, more precise control, and greater energy conservation and environmental protection.
[0003] Existing technologies still have the following shortcomings: Traditional single-shaft mixing systems rely solely on the unidirectional flow field generated by a single rotating blade, making it difficult to avoid mixing dead zones and prone to stratification or agglomeration of high-viscosity materials. While ordinary planetary mixers can improve uniformity, their fixed-axis planetary carrier structure results in limited shear strength, making it difficult to achieve nanoscale dispersion. Furthermore, conventional equipment typically uses independently driven multiple sets of mixing blades, which not only has a complex mechanical structure and high energy consumption, but also lacks coordination between the mixing units, resulting in an energy conversion efficiency generally below 60%. For solid-liquid mixing systems, existing technologies also present process control challenges such as uneven liquid addition and excessively high local concentrations, severely affecting batch stability. These limitations are particularly pronounced in emerging fields such as new energy slurries and high-end pharmaceutical formulations. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a high-speed powder homogenizer with multiple oil injection units, which solves the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed powder homogenizer with multiple oil injection units, comprising: The main body shell is equipped with a sealing port, and a drive motor is installed on the sealing port. A delivery pump is fixedly connected to one side of the main body shell, and multiple fuel injectors are installed on the inner wall of the main body shell. The delivery pump and the fuel injectors are connected in communication. An internal gear ring is fixedly connected to the inner wall of the sealing port, and a main gear is rotatably connected to the bottom axial position of the sealing port. The output end of the drive motor passes through the top of the sealing port and is fixedly connected to the main gear on the same axis. A base plate is fixedly connected to the bottom of the main gear on the same axis.
[0006] As a further embodiment of this utility model: a main stirring shaft is coaxially fixedly connected to the bottom of the base plate.
[0007] As a further embodiment of this utility model, the main stirring shaft is provided with multiple sets of main stirring blades.
[0008] As a further embodiment of this utility model: an annular gasket is fixedly connected to the bottom of the internal toothed ring, and the annular gasket is flush with the base plate.
[0009] As a further embodiment of this utility model: three planetary gears are provided inside the sealed port, and the spacing between two adjacent planetary gears among the three planetary gears is the same.
[0010] As a further embodiment of this utility model: the planetary gear meshes with both the main gear and the internal gear ring, and the planetary gear is in contact with the annular washer and the base plate and is slidably connected to both of them.
[0011] As a further embodiment of this utility model: a secondary stirring shaft is coaxially fixedly connected to the bottom of the planetary gear, and multiple sets of secondary stirring blades are provided on the secondary stirring shaft.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The triple meshing transmission system of main gear, planetary gear, and internal gear ring achieves the compound motion of the main and auxiliary stirring blades. This ensures overall material circulation at the macroscopic level and significantly improves mixing uniformity by forming a multi-dimensional high-shear zone through the planetary auxiliary blades. The unique synergistic effect of rotation and revolution ensures thorough mixing coverage, making it particularly suitable for high-viscosity materials and nanoscale dispersion requirements. The compact and reliable mechanical transmission structure achieves superior dispersion results in a shorter time compared to traditional stirring methods, while reducing energy consumption by more than 20% compared to a single stirring system. It has outstanding application value in fields with stringent mixing requirements, such as food, pharmaceuticals, and new energy. Attached Figure Description

[0015] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0016] like Figures 1-4 As shown, this utility model provides a technical solution: A high-speed powder homogenizer with multiple oil injection units, comprising: The main body shell 1 is equipped with a sealing port 2, and a drive motor 3 is installed on the sealing port 2. A delivery pump 4 is fixedly connected to one side of the main body shell 1. Multiple oil nozzles 5 are installed on the inner wall of the main body shell 1. The delivery pump 4 and the oil nozzles 5 are connected. The oil nozzles 5 can spray oil into the main body shell 1. During high-speed stirring, oil, water, solvent and other liquids are sprayed evenly to avoid local over-spraying or clumping. The delivery pump 4 can provide hydraulic pressure to the oil nozzles 5. An internal gear ring 6 is fixedly connected to the inner wall of the sealing port 2. A main gear 7 is rotatably connected to the bottom axial position of the sealing port 2. The output end of the drive motor 3 passes through the top of the sealing port 2 and is fixedly connected to the main gear 7 on the same axis. A base plate 8 is fixedly connected to the bottom of the main gear 7 on the same axis. A main stirring shaft 9 is coaxially fixedly connected to the bottom of the base plate 8. Multiple sets of main stirring blades 10 are mounted on the main stirring shaft 9. An annular gasket 11 is fixedly connected to the bottom of the internal gear ring 6, and the annular gasket 11 is flush with the base plate 8. Three planetary gears 12 are installed inside the sealing port 2. The spacing between adjacent planetary gears 12 is consistent. The planetary gears 12 mesh with both the main gear 7 and the internal gear ring 6. The planetary gears 12 are in contact with the annular gasket 11 and the base plate 8, and are slidably connected to both. A secondary stirring shaft 13 is coaxially fixedly connected to the bottom of the planetary gears 12, and a secondary stirring shaft 13 is provided with… Multiple sets of auxiliary stirring blades 14, when needed for material mixing, activate the drive motor 3. The drive motor 3 drives the main gear 7, main stirring shaft 9, and main stirring blades 10, which are coaxially fixed to its output end, to rotate. Simultaneously, since the planetary gear 12 meshes with both the main gear 7 and the internal gear ring 6, the planetary gear 12 rotates on its own axis and revolves around the main gear 7. The auxiliary stirring blades 14, in conjunction with the main stirring blades 10, enhance the mixing effect. This composite motion is transmitted to the auxiliary stirring blades 14 through the planetary carrier, causing them to form complex motion trajectories within the main shell 1. The main stirring blades 10 primarily generate macroscopic axial and radial flow, while the auxiliary stirring blades 14 generate local high-shear zones at different locations within the main shell 1 through planetary motion. The synergistic effect of both significantly improves both macroscopic mixing and microscopic dispersion of the material. This composite mixing method not only improves mixing efficiency but also ensures the uniformity of the material at various locations within the main shell 1, making it particularly suitable for processing high-viscosity, multiphase systems, or materials requiring high dispersion uniformity.
[0017] The working principle of this utility model is as follows: The fuel injector 5 can spray oil into the main body shell 1. During high-speed stirring, oil, water, solvent and other liquids are sprayed evenly to avoid local over-spraying or clumping. The delivery pump 4 can provide hydraulic pressure to the fuel injector 5. When material mixing is required, the drive motor 3 is started. The drive motor 3 drives the main gear 7, the main stirring shaft 9, and the main stirring blades 10, which are coaxially fixed to its output end, to rotate. Simultaneously, since the planetary gear 12 meshes with both the main gear 7 and the internal gear ring 6, the planetary gear 12 rotates on its own axis and revolves around the main gear 7. The auxiliary stirring blades 14, in conjunction with the main stirring blades 10, enhance the mixing effect. This composite motion is transmitted to the auxiliary stirring blades 14 through the planetary carrier, causing them to form complex motion trajectories within the main shell 1. The main stirring blades 10 primarily generate macroscopic axial and radial flow, while the auxiliary stirring blades 14 generate localized high-shear zones at different locations within the main shell 1 through planetary motion. The synergistic effect of both significantly improves both macroscopic mixing and microscopic dispersion of the material. This composite mixing method not only improves mixing efficiency but also ensures the uniformity of the material throughout the main shell 1, making it particularly suitable for processing high-viscosity, multiphase systems, or materials requiring high dispersion uniformity.
[0018] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
