Technical Field

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

[0002] With the rapid development of the new materials industry, the application scenarios of new materials such as composite materials, nanomaterials, and high-viscosity functional polymer materials are constantly expanding, which puts forward stringent requirements on the uniformity, dispersion and process stability of material mixing.

[0003] In the existing technology, the stirring mechanisms for new materials are mainly divided into paddle type, ribbon type, planetary type and other types. Although these mechanisms can meet the basic stirring requirements, when dealing with high viscosity materials, there is a common problem of material residue on the inner wall of the tank. Specifically, the existing stirring mechanisms lack a mechanism to scrape off the material attached to the inner wall of the tank and participate in the mixing, which will lead to a decrease in the uniformity of material mixing. Therefore, we need to propose a new material mixing and stirring mechanism. Utility Model Content

By setting an annular scraper that fits against the inner wall of the tank, and a stirring frame, positioning frame and lifting assembly that can drive it to rotate and move up and down, it achieves the effect of efficiently removing material residue from the inner wall and improving the uniformity of material mixing, thereby solving the problems mentioned in the background art.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A novel material mixing and stirring mechanism includes: a tank body 1, which has an annular scraper 2 inside. The outer wall of the annular scraper 2 is in contact with the inner wall of the tank body 1. The tank body 1 is integrally formed from SUS316L stainless steel. By setting the inner wall to be mirror polished (Ra≤0.4μm) and hard chrome plated (plating thickness 0.05mm), the effect of reducing material adhesion and improving the wear resistance of the tank body is achieved.

[0025] The stirring rack 3 is connected to the inner wall of the annular scraper 2. The top of the stirring rack 3 passes through the tank 1 and is connected to the first drive motor 4. The outer shell 5 is fixedly installed on the outside of the first drive motor 4. The stirring rack 3 is designed as a "Y"-shaped double-arm structure. The first drive motor 4 adopts an explosion-proof variable frequency motor (IE3 energy efficiency level, protection level IP66). By setting a vector control algorithm and encoder feedback (accuracy ±0.1°), a precise control effect of speed stability error ≤ ±0.5% is achieved when the load fluctuates by ±20%.

[0026] The positioning frame 6 is fixedly connected to the top of the tank 1, and the positioning frame 6 is equipped with a lifting component 7 for moving the outer shell 5, the stirring frame 3 and the annular scraper 2 up and down. By setting the lifting component 7, the height position of the outer shell 5, the stirring frame 3 and the annular scraper 2 can be flexibly adjusted to meet the requirements of different stirring stages for stirring position and scraping position.

[0027] The lifting assembly 7 includes a lead screw 701, a second drive motor 702, and a movable plate 703. The two ends of the lead screw 701 are rotatably connected to the inner top and inner bottom of the positioning frame 6, respectively, and the top end of the lead screw 701 passes through the positioning frame 6 and is connected to the second drive motor 702. A threaded sleeve 704 is fixedly embedded on the movable plate 703. The lead screw 701 is threadedly connected to the threaded sleeve 704. One side of the movable plate 703 is fixedly connected to the outer shell 5. By setting the threaded engagement of the lead screw 701 and the threaded sleeve 704 and driving the lead screw 701 to rotate by the second drive motor 702, the up and down movement of the movable plate 703 is precisely controlled, thereby achieving the effect of smooth lifting of the outer shell 5 and other components.

[0028] A guide groove 8 is provided on one inner wall of the positioning frame 6. A guide block 9 that matches the guide groove 8 is fixedly connected to one side of the movable plate 703. The guide block 9 is slidably connected inside the guide groove 8. By setting the guide groove 8 and the guide block 9 together, the movement direction of the movable plate 703 is restricted and guided, preventing the movable plate 703 from deviating during movement and ensuring the stability of the lifting process.

[0029] A sliding sleeve 10 is fixedly installed on the top of the tank 1. The inner wall of the sliding sleeve 10 is smooth, and the stirring rack 3 is inserted into the inside of the sliding sleeve 10. By setting the sliding sleeve 10 with a smooth inner wall, the friction between the stirring rack 3 and the tank 1 during the up-down movement and rotation is reduced, making the movement of the stirring rack 3 smoother and reducing energy loss.

[0030] The top of the mixing rack 3 is connected to the output shaft of the first drive motor 4 via a flange. By setting a flange to connect the top of the mixing rack 3 and the output shaft of the first drive motor 4, the installation, disassembly and maintenance of the two are facilitated, while ensuring the firmness and stability of the connection.

[0031] The vertical cross-section of the annular scraper 2 gradually increases from bottom to top. By setting the vertical cross-section of the annular scraper 2 to gradually increase from bottom to top, the material at different heights on the inner wall of the tank 1 can be scraped more comprehensively during the descent of the annular scraper 2, thereby improving the scraping efficiency and effect.

[0032] A feed pipe 11 is fixedly connected to the outer wall of the tank body 1, and a discharge pipe 12 is fixedly connected to the bottom of the tank body 1. A valve is connected to the discharge pipe 12. By setting the feed pipe 11 and the discharge pipe 12 with the valve, it is possible to facilitate the addition of materials and the discharge of the mixture after stirring. The discharge speed and start / stop can be controlled by the valve.

[0033] Working Principle: When new materials need to be mixed, they are first added to the tank 1 through the feed pipe 11. The first drive motor 4 is started, which drives the stirring frame 3 to rotate, and the stirring frame 3 mixes the materials in the tank 1. During the mixing process, if it is necessary to adjust the height of the stirring frame 3 and the annular scraper 2, the second drive motor 702 is started, which drives the lead screw 701 to rotate. The lead screw 701 is threadedly engaged with the screw sleeve 704, causing the movable plate 703 to move up and down under the guidance of the guide block 9 and the guide groove 8. The movable plate 703 drives the outer shell 5, the first drive motor 4, the stirring frame 3, and the annular scraper 2 to move up and down synchronously. The stirring frame 3 slides within the sliding sleeve 10 to ensure its stability. During the up and down movement, the outer wall of the annular scraper 2 adheres to the inner wall of the tank 1, scraping off the material adhering to the inner wall. After mixing is complete, open the valve on the discharge pipe 12 and discharge the mixed material from the discharge pipe 12. It is worth noting that the lifting component 7 can simultaneously drive the annular scraper 2 and the mixing frame 3 to move up and down, which is beneficial to further improve the uniformity of material mixing. The effect of controlling the annular scraper 2 and the mixing frame 3 to move up and down can be achieved by controlling the second drive motor 702 to rotate forward and backward.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
