Description

Technical Field

[0001] This utility model relates to the technical field of vertical stirred mill liners, specifically a spiral groove wear-resistant composite liner for a vertical stirred mill. Background Technology

[0002] In the production application of vertical stirred mills, the liner plate, as a core wear-resistant component, directly affects the grinding efficiency and service life of the equipment due to its installation stability and the flatness of its inner wall.

[0003] Existing liners mostly adopt an integral structure or a multi-piece bolt splicing design, which easily leads to dents or protrusions on the inner wall after installation. The bolt heads of spliced ​​liners often protrude from the inner wall, or local dents are caused by the splicing gaps between liners. This can easily cause material jamming during the grinding process, which not only reduces the grinding uniformity but also aggravates abnormal wear between the liner and the material, shortens the equipment maintenance cycle, and increases the production cost of enterprises. Therefore, it is necessary to propose a spiral groove wear-resistant composite liner for vertical stirred mills. Utility Model Content

[0004] The purpose of this utility model is to provide a spiral groove wear-resistant composite liner for a vertical stirred mill, so as to solve the technical problems of reduced grinding uniformity and shortened equipment use and maintenance cycle caused by jamming due to foreign objects during the use of the liner.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A spiral groove wear-resistant composite liner for a vertical stirred mill includes a first liner and a second liner, which are fastened together by a snap-fit ​​assembly. Both the first and second liners have a receiving groove on their inner walls. A threaded hole is formed through the groove wall of the receiving groove, and a threaded rod is threaded into the threaded hole. One end of the threaded rod extends into the receiving groove and is fixedly connected to a clamping plate. A rectangular groove is formed on both the clamping plate and the threaded rod. A sealing plate is slidably connected within the receiving groove. A placement groove is formed on the sealing plate at a position corresponding to the clamping plate. A rectangular rod is fixedly connected within the placement groove, extending into the rectangular groove. A tension spring is fixedly connected between the rectangular rod and the rectangular groove.

[0007] As a preferred embodiment of this utility model, the buckle assembly includes a groove and a protrusion. The groove is formed on the first liner, and the protrusion is fixedly connected to the second liner and slidably connected in the groove.

[0008] As a preferred embodiment of this utility model, one end of the tension spring is fixedly connected to the bottom of the rectangular groove, and the other end of the tension spring is fixedly connected to the end of the rectangular rod located inside the rectangular groove.

[0009] As a preferred embodiment of this utility model, the clamping plate is sleeved in the placement groove.

[0010] As a preferred embodiment of this utility model, the outer wall of the sealing plate is arranged to overlap with the inner walls of the first liner and the second liner.

[0011] Compared with the prior art, the beneficial effects of the spiral groove wear-resistant composite liner for a vertical stirred mill of this utility model are as follows: the first and second liners are joined into a cylindrical shape by a snap-fit ​​assembly and inserted into the equipment. Then, the threaded holes and mounting screw holes are aligned, and the sealing plate is rotated to drive the threaded rod to connect and fix it. The clamping plate is pressed against the bottom of the receiving groove to complete the stable installation. After fixing, the sealing plate is released, and the tension spring will pull the rectangular rod to pull the sealing plate into the receiving groove, so that it completely overlaps with the inner wall of the liner without any depressions or protrusions. This avoids problems such as material jamming and reduced grinding efficiency caused by uneven inner walls, ensuring that the vertical stirred mill always maintains a stable operating state and significantly improving the equipment's performance and reliability.

[0021] See Figures 1-4 As shown in the figure, an embodiment of the present invention provides a spiral groove wear-resistant composite liner for a vertical stirred mill, comprising a first liner 1 and a second liner 2, which are fastened together by a snap-fit ​​assembly. Both the first liner 1 and the second liner 2 have a receiving groove 3 on their inner walls. A threaded hole 4 is provided through the groove wall of the receiving groove 3, and a threaded rod 5 is threaded into the threaded hole 4. One end of the threaded rod 5 extends into the receiving groove 3 and is fixedly connected to a clamping plate 6. A rectangular groove 7 is provided on both the clamping plate 6 and the threaded rod 5. A sealing plate 8 is slidably connected within the receiving groove 3. A placement groove 9 is provided on the sealing plate 8 at a position corresponding to the clamping plate 6. A rectangular rod 10 is fixedly connected within the placement groove 9, extending into the rectangular groove 7. A tension spring 11 is fixedly connected between the rectangular rod 10 and the rectangular groove 7.

[0022] The snap-fit ​​assembly includes a groove 12 and a protrusion 13. The groove 12 is formed on the first liner 1, and the protrusion 13 is fixedly connected to the second liner 2 and slidably connected in the groove 12.

[0023] One end of the tension spring 11 is fixedly connected to the bottom of the rectangular groove 7, and the other end of the tension spring 11 is fixedly connected to the end of the rectangular rod 10 located in the rectangular groove 7. The tension spring 11 will pull the rectangular rod 10 to move under the support of the rectangular groove 7. The clamping plate 6 is sleeved in the placement groove 9. The outer wall of the sealing plate 8 is set to overlap with the inner wall of the first liner 1 and the second liner 2, so that the inner walls of the first liner 1 and the second liner 2 will not be recessed or protruded after installation.

[0024] In use, first insert the protrusion 13 on the second liner 2 into the groove 12, then push the second liner 2 to move so that the first liner 1 and the second liner 2 together form a cylindrical liner, and insert the liner into the vertical mixing mill.

[0025] Align the threaded holes 4 on the first liner plate 1 and the second liner plate 2 with the mounting screw holes on the vertical mixing mill. Insert the threaded rod 5 into the threaded hole 4. Rotate the sealing plate 8. The sealing plate 8 drives the threaded rod 5 to rotate through the snap-fit ​​between the rectangular rod 10 and the rectangular groove 7. This makes the threaded rod 5 threadedly connected to the threaded hole 4 and the mounting screw hole, until the threaded rod 5 drives the clamping plate 6 to abut against the bottom of the receiving groove 3, thereby clamping and fixing the first liner plate 1 and the second liner plate 2 on the inner wall of the vertical mixing mill.

[0026] When the sealing plate 8 is released, the tension spring 11 will pull the rectangular rod 10 to move under the support of the rectangular groove 7. The rectangular rod 10 will pull the sealing plate 8 into the receiving groove 3 and make it overlap with the inner wall of the first liner 1 and the second liner 2, thereby avoiding obvious depressions or protrusions in the inner walls of the first liner 1 and the second liner 2, which would affect the use of the vertical mixing mill.

[0027] The foregoing has shown and described the basic principles of the present invention. The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the present invention without departing from the scope of the present invention should be included within the protection scope of the present invention.
