Abstract
Description
Technical Field
[0001] This utility model relates to the field of tube mill technology, and in particular to a split-flow vortex baffle ring for tube mills. Background Technology
[0002] In current technologies, the baffle ring is typically a crucial component of tube mills. Its primary function is to control the residence time of material within the mill, preventing excessive material outflow and thus improving grinding efficiency. The diverting vortex baffle ring offers significant advantages in improving grinding efficiency, reducing energy consumption, and minimizing wear. Its optimized material and airflow distribution effectively enhances mill operating efficiency and reduces problems caused by material accumulation and poor airflow. Furthermore, its adjustable design and the application of wear-resistant materials further extend the baffle ring's service life and reduce maintenance costs.
[0003] However, existing technologies still have shortcomings, such as the following:
[0004] During the operation of a tube mill, frequent friction and collisions occur between the material and the retaining ring, leading to rapid wear on the retaining ring surface. This wear not only reduces the service life of the retaining ring but may also affect its sealing performance, causing material leakage or reduced grinding efficiency. Furthermore, once the retaining ring is worn, the replacement process is often complex, requiring disassembly of the entire unit or extensive bolting operations. This is not only time-consuming and labor-intensive but also leads to prolonged equipment downtime, impacting production efficiency. Utility Model Content
[0005] This invention provides a split-flow vortex baffle ring for tube mills to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A split-flow vortex baffle ring for a tube mill includes a fixed structure, a replacement structure sleeved on the top of the outer wall of the fixed structure, the fixed structure including a fixed base plate, a fixed protective groove opened on the top of the fixed base plate, a fixed installation groove opened on the bottom of the inner side of the fixed protective groove, and a fixed column fixedly connected to the top of the fixed base plate and on one side of the fixed protective groove.
[0008] Preferably, a triangular limiting post is fixedly connected to the middle of the top of the fixed post, and the model of the triangular limiting post is a column triangle.
[0009] Preferably, a mating groove is provided on the outer wall of the top of the fixed column and around the periphery of the triangular limiting column, and a threaded groove is provided in the middle of the top of the triangular limiting column.
[0010] Preferably, the replacement structure includes a replacement sleeve with rounded corners, a wear-resistant coating fixedly connected to one side of the outer wall of the replacement sleeve, and a docking frame fixedly connected to the bottom of the replacement sleeve.
[0011] Preferably, the top of the replacement sleeve has an anti-collision groove in the middle, which is used to protect the inner side from collisions.
[0012] Preferably, a threaded rod is threaded to the bottom of the inner side of the anti-collision groove, and a rotating handle is fixedly connected to the top of the threaded rod.
[0013] In summary, this technical solution has the following main advantages:
[0014] The fixed column and its top triangular limiting column provide accurate positioning and stable support for the installation of the replacement structure. The triangular model of the vertical column of the triangular limiting column can match the inner shape of the replacement sleeve, so that the replacement sleeve can be accurately fitted onto its outer wall, ensuring the stability and reliability of the replacement structure after installation and preventing the replacement sleeve from shaking or shifting during use;
[0015] The wear-resistant coating on the outer wall of the replacement sleeve can effectively improve its wear resistance. During the operation of the tube mill, friction and collision will occur between the material and the baffle ring. The wear-resistant coating can reduce the wear of the replacement sleeve itself caused by these frictions and collisions, thereby extending the service life of the replacement sleeve and reducing the maintenance cost and replacement frequency of the equipment.
[0016] When the replacement sleeve needs to be replaced due to wear or other reasons, simply rotate the handle to unscrew the threaded rod from the threaded groove, and the replacement sleeve can be removed from the triangular limit post. The operation is simple and convenient, and the replacement work can be completed quickly, reducing equipment downtime and improving production efficiency. Attached Figure Description
