The development of heating and stirring technology has greatly improved the efficiency of material mixing and heating, resulting in a significant improvement in product quality, and it is widely used in various production processes.
[0003] Traditional technologies employ various methods to achieve material heating and mixing. One approach involves installing a heating jacket on the outer layer of the mixing tank, utilizing heat transfer principles to heat the material inside. Another method, to further improve the uniformity of material heating, a material pipe is installed on the mixing tank, with its two ends connecting to the inner cavity of the tank from the top and bottom respectively. A steam pipe is installed on the outer wall of the material pipe for auxiliary heating. The circulation of the material within the material pipe ensures more thorough heating.
[0004] However, during the mixing process, there may be unmelted material in the mixing tank. When this unmelted material flows into the material pipe, it can cause blockage. This not only affects the normal circulation of materials and the heating effect, but may also cause the entire heating and mixing system to malfunction, impacting production efficiency. Utility Model Content

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0027] This application discloses a filtration device for a heated mixing tank. The heated mixing tank has a discharge port 1 at its lower end and a material pipe 2. The inner cavity of the material pipe 2 is connected to the inner cavity of the heated mixing tank through the discharge port 1. The heated mixing tank includes a drive component 3 and a stirring shaft 4. The drive component 3 drives the stirring shaft 4 to rotate. A disturbance rod 41 is connected to the periphery of the stirring shaft 4, and the disturbance rod 41 extends along the length of the stirring shaft 4.
[0028] Reference Figure 1 and Figure 2 A filtration device for a heated mixing tank includes a filter cover 5 and a scraper 6. The filter cover 5 is disposed in the inner cavity of the heated mixing tank, and has a plurality of filter holes 51 extending through it. The filter cover 5 has a filter surface 52, and the filter surface 52 of the filter cover 5 protrudes into the inner cavity of the mixing tank to increase the filter surface area 52, reduce the probability of clogging, and improve the filtration efficiency.
[0029] The filter cover 5 is generally made of metal, such as stainless steel, which has good corrosion resistance and strength. Of course, engineering plastics, such as polyvinyl chloride (PVC), can also be used, as they are less expensive and lighter. The filter holes come in various shapes, such as round and square. Round filter holes are easier to manufacture, while square filter holes can improve filtration accuracy in certain situations. The filter holes are evenly distributed on the filter cover 5 so that the material can pass through it uniformly.
[0030] The filter surface 52 is an arc surface. Compared with the flat filter surface 52, the arc surface can better guide the material flow and reduce the accumulation of material on the filter surface 52. It can make the material disperse more smoothly in all directions during the filtration process and avoid blockage caused by excessive local pressure.
[0031] The scraper 6 is located at the lower end of the agitator 41. During the rotation of the stirring shaft 4, the scraper 6 scrapes across the filter surface 52. The scraper 6 includes several silicone brush strips. The silicone brush strips are soft and can effectively scrape away impurities on the filter surface 52 without damaging the filter cover 5. The silicone brush strips have good elasticity and can adapt to the shape of the filter surface 52 to ensure the scraping effect.
[0032] Specifically, the end of the disturbance rod 41 is connected to a connector 42, which has several insertion holes 421 extending through it. The insertion holes 421 extend along the length of the disturbance rod 41, and silicone brush strips are inserted into these holes. Each insertion hole 421 corresponds to a specific silicone brush strip. This connection method facilitates the installation and replacement of the silicone brush strips. If a silicone brush strip is damaged, it can be simply removed and replaced without replacing the entire scraper component 6.
[0033] Furthermore, the upper end of the silicone brush strip is provided with an abutment 62, which is used to abut against the upper surface of the connector 42. The abutment 62 can prevent the silicone brush strip from coming out of the insertion hole 421 during use, ensuring the stability of the scraper 6. The abutment 62 is generally a rubber pad with a certain degree of elasticity, which can fit tightly against the connector 42.
[0034] Material pipe 2 is detachably connected to the heating and mixing tank to facilitate cleaning and maintenance. When blockages or dirt accumulate inside material pipe 2, it can be easily disassembled for cleaning. The detachable connection can be achieved using a flange connection, which provides a secure and well-sealed connection, or a clamp connection, which is simple to install and disassemble.
[0035] The filter cover 5 is connected to the material pipe 2, forming a single unit with it, ensuring that the material is filtered before entering the material pipe 2. This connection method guarantees the effectiveness of filtration and prevents unfiltered material from directly entering the material pipe 2. The connection can be made by welding, resulting in a strong and reliable connection, or by bolting, which facilitates disassembly and maintenance.
[0036] The implementation principle of a filtration device for a heated mixing tank is as follows: During operation, the material is heated and stirred within the tank. A filter cover 5 is installed inside the tank, with its filter surface 52 protruding and extending to increase the filter surface area. Incompletely melted material is blocked by the filter cover 5, preventing it from entering the material pipe 2 and causing blockage. The drive unit 3 drives the stirring shaft 4 to rotate, and the agitator 41 rotates with the stirring shaft 4 to agitate the material, enhancing its flowability. During rotation, the silicone brush strip on the scraper 6 scrapes across the filter surface 52, promptly removing impurities and ensuring effective filtration. The material pipe 2 is detachably connected to the heated mixing tank for easy cleaning and maintenance. The filter cover 5 is connected to the material pipe 2 to ensure effective filtration. This entire filtration device effectively solves the problem of easy blockage of the material pipe 2 in existing technologies, improves the working efficiency and stability of the heated mixing tank, and reduces maintenance costs and time.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
