Description

Technical Field

[0001] This utility model relates to the field of stirring device technology, specifically a new material stirring device. Background Technology

[0002] Materials refer to structural materials with excellent performance and functional materials with special properties that have recently been developed or are under development. Structural materials mainly utilize their mechanical properties such as strength, toughness, hardness, and elasticity, such as new ceramic materials and amorphous alloys. Functional materials mainly utilize their electrical, optical, acoustic, magnetic, and thermal functions and physical effects. In recent years, the new materials researched and developed in the world mainly include new metallic materials, fine ceramics, optical fibers, pitchblende, and activated carbon, etc.

[0003] A novel material mixing device, as disclosed in announcement number CN220696456U, includes a mixing tank, a drive mechanism, and a mixing mechanism. The mixing tank has a feed inlet at its top, and the drive mechanism is installed on top of the mixing tank. The mixing mechanism is located inside the mixing tank and connected to the drive mechanism. The mixing mechanism includes a mixing shaft, mixing rods, mixing teeth, and a mixing arc-shaped plate. One end of the mixing shaft is installed on the top surface of the mixing tank. Multiple mixing rods are arranged radially on the mixing shaft, and mixing arc-shaped plates are installed between the mixing rods. Mixing teeth are installed at the bottom of the mixing rods. The arc-shaped surface of the mixing arc-shaped plate can lift the new material in the central area to a certain height to the mixing tooth area of ​​the next layer. The mixing teeth are used for stirring, and the material is gradually lifted to the top for uniform mixing, resulting in a more uniform mixing effect and better mixing of the new material. Furthermore, existing mixing devices have the following disadvantages in use:

[0004] (1) Existing mixing devices do not have self-cleaning capabilities, which means that when the equipment is working, the residual new material will adhere to the inner wall of the mixing tank, resulting in uneven mixing of the material and affecting the quality of mixing the new material.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0032] The drive motor 1003 drives the stirring shaft 3 to rotate, causing the spiral teeth 4 and the stirring rod 5 to rotate. This causes the scraper 8 to scrape the interior of the mixing tank 1 laterally. The telescopic cylinder 1002 drives the telescopic rod 1010 to extend and retract, causing the stirring shaft 3 to move up and down. The moving stirring shaft 3 drives the annular frame 7 and the scraper 9 to scrape the inner wall of the mixing tank 1 longitudinally and reciprocally, dynamically scraping away adhering materials.

[0033] For specific usage, please refer to... Figures 1 to 4As shown, new material is poured into the mixing tank 1 through the feed pipe 2. The drive motor 1003 and the telescopic cylinder 1002 are simultaneously activated via the control panel located on the front of the mixing tank 1. The drive motor 1003 rotates, and the telescopic cylinder 1002 pushes the telescopic rod 1010 to reciprocate. The drive motor 1003 drives the mixing shaft 3 to rotate, causing the spiral teeth 4 and the mixing rod 5 to rotate. This causes the scraper 8 to laterally scrape the interior of the mixing tank 1. The telescopic cylinder 1002 drives the telescopic rod 1010 to extend and retract, causing the mixing shaft 3 to move up and down. The moving mixing shaft 3 drives the annular frame 7 and the scraper 9 to longitudinally scrape the inner wall of the mixing tank 1. The spiral teeth 4 push the new material to circulate axially up and down, preventing stratification. The mixing rod 5 performs radial shearing, breaking up agglomerates and improving uniformity. The lifting and rotating structure 10 drives the mixing shaft 3 to rotate up and down, allowing the new material to flow in three-dimensional space, avoiding stratification or dead zones caused by traditional fixed mixing, and improving mixing efficiency.
