[0002] In industrial production, high-speed mixers are widely used in processes such as mixing, dispersing, and emulsifying various materials. As the core component of a high-speed mixer, the impeller's structure and performance directly affect the mixer's efficiency and mixing quality. Existing impellers for high-speed mixers have some shortcomings, such as uneven mixing leading to poor mixing results; high resistance during high-speed rotation resulting in excessive energy consumption; and poor wear resistance and short service life, increasing equipment maintenance costs. Therefore, it is necessary to develop an improved impeller for high-speed mixers to address these issues. Utility Model Content

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0021] Example:
[0022] Please see Figure 1-3 This utility model provides a technical solution: an impeller for a high-speed mixer, including an impeller shaft 1 and an impeller body 2 mounted on the impeller shaft 1. The impeller body 2 includes a plurality of blades 3, which are spirally distributed on the outer circumferential surface of the impeller shaft 1, and the edges of the blades 3 are provided with serrated structures 4.
[0023] The blades 3 are made of high-strength, wear-resistant materials, such as cemented carbide and ceramics, to improve their wear resistance. Multiple mounting grooves 5 are provided on the outer circumferential surface of the impeller shaft 1. One end of the blade 3 is fixedly mounted in the mounting groove 5 with bolts, facilitating blade installation and removal. A protective coating 6 is provided on the outer circumferential surface of the impeller body 2. The protective coating 6 is made of corrosion-resistant and high-temperature-resistant materials, such as polytetrafluoroethylene and epoxy resin, to protect the impeller body 2. Multiple guide grooves 7 are provided on the surface of the blades 3, extending along the length of the blades 3 to guide material flow. A connecting flange 8 is provided at one end of the impeller shaft 1, and the connecting flange 8 has multiple mounting holes 9 for connecting the impeller to the drive unit of the mixer.
[0024] Working principle: When using the impeller of this high-speed mixer, the impeller is connected to the drive device of the mixer through the connecting flange 8. The drive device drives the impeller shaft 1 to rotate at high speed, and the blades 3 on the impeller body 2 rotate at high speed accordingly. The spirally distributed blades 3 make the material form a spiral flow path for mixing. The serrated structure 4 on the edge of the blades 3 increases the friction with the material and breaks up agglomerates. The guide grooves 7 on the surface of the blades 3 guide the material flow and reduce resistance. The protective coating 6 protects the impeller body 2 from corrosion and high temperature.
[0025] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
