Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a feeding mechanism for an air classifier. Background Technology

[0002] In numerous industrial production sectors, especially the powder processing industry, air classifiers play a crucial role. They can precisely separate mixed powders into products of different particle size classes based on particle size, shape, and density characteristics. Widely used in industries such as chemical, pharmaceutical, food, and mining, they are significant for improving product quality and meeting diverse production needs. The feeding mechanism, as a key component of the air classifier, directly affects the stability and effectiveness of the entire classification process.

[0003] However, traditional air classifier feeding mechanisms are inadequate in terms of material mixing uniformity. Most traditional feeding mechanisms lack effective mixing devices, resulting in insufficient mixing of materials before they enter the air classifier. This leads to uneven mixing and inconsistent distribution of particles of different sizes and properties. Furthermore, they cannot effectively break up larger or agglomerated materials, making it difficult for the air classifier to accurately separate particles according to their characteristics during the classification process. This results in decreased classification accuracy, a wide particle size distribution in the product, and an inability to meet the requirements of high-precision production. Therefore, this application provides a feeding mechanism for an air classifier to meet these requirements. Utility Model Content

The setting of scrapers and blades can effectively prevent the material from adhering to the inner wall of the feed tank, avoiding material accumulation and waste, while ensuring the smooth falling of the material and improving the feeding efficiency.

[0026] like Figure 1 and Figure 5As shown, an embodiment of this utility model provides a feeding mechanism for an air classifier, including a feeding tank 1. The bottom of the feeding tank 1 has a bucket-shaped structure and a discharge port 2 is provided at the bottom. A feeding pipe 3 is connected to the bottom of the feeding tank 1. One end of the feeding pipe 3 has a feeding interface 4 at its top. The feeding interface 4 is connected to the discharge port 2 of the feeding tank 1 through a flange. This connection method facilitates disassembly and installation, and makes it convenient for equipment maintenance and repair. An auger 25 is rotatably installed inside the feeding pipe 3. The auger 25 is distributed along the length of the feeding pipe 3. A first motor 6 is installed at one end of the feeding pipe 3 to drive the auger 25 to rotate. The feeding pipe 3 has a feeding port 5 for feeding material toward the air classifier. When the first motor 6 is started, it drives the auger 25 to rotate. The auger 25 can evenly transport the material entering the feeding pipe 3 to the feeding port 5. The feeding port 5 is arranged at the bottom of the feeding pipe 3 away from the feeding interface 4, so as to accurately feed the material into the air classifier.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, a horizontal plate 9 is fixed to the top of the feed tank 1. A shaft 10 is vertically inserted through the horizontal plate 9. Multiple pairs of stirring blades 13 are arranged on the side wall of the portion of the shaft 10 that extends into the feed tank 1. The multiple pairs of stirring blades 13 are staggered, which increases the stirring area and improves the stirring effect. A scraper 14 is provided at the end of each pair of stirring blades 13 away from the shaft 10. The scraper 14 is vertically distributed and contacts the inner side wall of the feed tank 1. A scraper blade 24 is provided on the side of the scraper 14 away from the stirring blades 13. The scraper blade 24 is curved in an arc shape to one side. The arrangement of the scraper 14 and scraper blade 24 can prevent the material from adhering to the inner side wall of the feed tank 1 and ensure the smooth falling of the material. A hammer 15 is connected to the bottom end of the shaft 10. During the rotation of the shaft 10, the hammer 15 can further crush and stir the material, making the material more uniform. A second motor 11 is provided at the top of the horizontal plate 9 to drive the shaft 10 to rotate.

[0028] like Figure 1 , Figure 2 and Figure 3As shown, the bottom of the second motor 11 is equipped with a support plate 17, and the top end of the shaft 10 is rotatably mounted on the support plate 17 and coaxially connected to the output shaft of the second motor 11. Thus, when the second motor 11 starts, it can drive the shaft 10 to rotate, thereby driving the stirring blade 13, scraper 14, scraper blade 24, and hammer 15 to rotate together. A hammering drive mechanism 12 is mounted on the horizontal plate 9 for synchronously driving the shaft 10 and the second motor 11 to reciprocate. The hammering drive mechanism 12 includes a third motor 23, a rotating arm 21, a slide rail 19, and a pulley 20. A connecting plate 18 is vertically fixed to one side of the bottom of the support plate 17, and the slide rail 19 is horizontally fixed to the bottom end of the connecting plate 18. The pulley 20 is slidably embedded in the slide rail 19. A fixed arm 22 is fixed on the horizontal plate 9, and the third motor 23 is fixedly mounted on the fixed arm 22. The rotating arm 21 is radially mounted on the output shaft of the third motor 23, and the other end of the rotating arm 21 is rotatably connected to the pulley 20. When the third motor 23 starts, it drives the rotating arm 21 to rotate. The rotating arm 21 drives the pulley 20 to slide back and forth along the slide rail 19, thereby realizing the synchronous reciprocating lifting and lowering of the shaft 10 and the second motor 11.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a sliding sleeve 16 is also fitted on the horizontal plate 9. The sliding sleeve 16 is slidably engaged with the shaft 10. The sliding sleeve 16 serves as a guide to ensure the stability of the shaft 10 during reciprocating lifting and lowering. A ring plate 7 is provided on the bottom side wall of the feed tank 1, and an assembly hole 8 is provided on the ring plate 7.

[0030] The working principle of the technical solution provided by this utility model is as follows: Working principle: When using the feeding mechanism for the air classifier, the material is first poured into the feed tank 1. The second motor 11 is started, driving the shaft 10 to rotate. The stirring blades 13 on the shaft 10 stir the material, ensuring uniform mixing. Simultaneously, the scraper 14 and scraper blades 24 scrape off material adhering to the inner wall of the feed tank 1, preventing material accumulation. The hammer 15 crushes the material during rotation, further improving its properties. The third motor 23 in the hammer drive mechanism 12 is started, driving the rotating arm 21 to rotate. The rotating arm 21 drives the pulley 20 to slide back and forth along the slide rail 19, causing the shaft 10 and the second motor 11 to move up and down synchronously. During the reciprocating movement of the shaft 10, the hammer 15 hammers the material, further crushing it and making it looser and more uniform.

[0031] Start the first motor 6, which drives the auger 25 to rotate. The auger 25 evenly conveys the material that has been stirred and crushed in the feed tank 1 to the feed pipe 3, and then feeds the material into the air classifier through the feed port 5 to complete the feeding process.

[0032] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
