Description

Technical Field

[0001] This utility model relates to the field of cement mill technology, specifically to an adaptive cylinder liner structure. Background Technology

[0002] Cement clinker production is a key step in the cement manufacturing process, mainly including raw meal preparation, clinker firing, and cooling.

[0003] Cement mills are key equipment for further pulverizing materials after they have been crushed. They are widely used in the cement production industry. In cement mills, liners are key components inside the mill. The main function of liners is to protect the mill cylinder from direct impact and wear from grinding media and materials, thereby improving grinding efficiency and increasing output.

[0004] In cement mills, the installation surface size of the cement mill liner is generally designed according to the diameter of the cylinder. Liners of different diameter cylinders generally cannot be borrowed from each other, resulting in relatively high production costs and inconvenience in use. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive cylindrical liner structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adaptive cylindrical liner structure includes a cement mill and a liner. The liner is installed on the inner circumferential wall of the cement mill. The liner includes a plate body. A first outer wall structure and a second outer wall structure are provided on the outer wall surface of the plate body near the inner wall of the cement mill. The second outer wall structure is symmetrically located on both sides of the first outer wall structure.

[0008] As a preferred embodiment of this utility model, the radius of the first outer wall structure is greater than the radius of the second outer wall structure.

[0009] As a preferred embodiment of this utility model, when the radius of the first outer wall structure matches the radius of the inner wall of the cement mill, the first outer wall structure and the inner wall structure of the cement mill are matched and fit together.

[0010] As a preferred embodiment of this utility model, when the radius of the second outer wall structure matches the radius of the inner wall of the cement mill, the second outer wall structure and the inner wall structure of the cement mill are matched and fit together.

[0011] As a preferred embodiment of this utility model, both the first outer wall structure and the second outer wall structure are arc-shaped structures.

[0012] As a preferred embodiment of this utility model, the liner plate has a plurality of mounting holes on its plate body, which are evenly distributed along the length direction of the plate body, for fixing the liner plate to the inner wall of the cement mill.

[0013] As a preferred embodiment of this utility model, the plate body of the liner is made of high-strength wear-resistant material, and the surfaces of the first outer wall structure and the second outer wall structure are both provided with wear-resistant coatings.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In response to the problems mentioned in the background art, this application designs a first outer wall structure and a second outer wall structure, so that the liner can adapt to cement mill cylinders of different diameters, reducing the problem of needing to customize the liner due to different cylinder diameters and significantly improving the versatility of the liner;

[0016] Because the liner can accommodate cylinders of various diameters, the need for customized production is reduced, thereby lowering manufacturing and inventory management costs.

[0017] The use of high-strength wear-resistant materials and wear-resistant coatings significantly improves the service life of the liners, reduces frequent replacements due to wear, and lowers maintenance costs.

[0018] By setting multiple mounting holes on the plate, the liner can be firmly fixed to the inner wall of the cement mill, reducing wear and damage caused by loose installation;

[0019] The arc-shaped outer wall design allows for a better fit to the mill cylinder, reducing the gap between the material and the liner, thereby improving grinding efficiency and output.

[0027] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0028] Please see Figure 1-5 This utility model provides a technical solution: an adaptive cylindrical liner structure, including a cement mill 1 and a liner 2. The liner 2 is installed on the inner circumferential wall of the cement mill 1. The liner 2 includes a plate body 21, and multiple mounting holes 22 are provided on the plate body 21. The mounting holes 22 are evenly distributed along the length direction of the plate body 21 for fixing the liner 2 to the inner wall of the cement mill 1. A first outer wall structure 211 and a second outer wall structure 212 are provided on the outer wall surface of the plate body 21 near the inner wall of the cement mill 1. The second outer wall structure 212 is symmetrically located on both sides of the first outer wall structure 211. Both the first outer wall structure 211 and the second outer wall structure 212 are arc-shaped structures. The radius of the first outer wall structure 211 is larger than the radius of the second outer wall structure 212. When the radius of the first outer wall structure 211 matches the radius of the inner wall of the cement mill 1 (see Appendix). Figure 4 At this point, the first outer wall structure 211 matches and fits the inner wall structure of the cement mill 1. When the radius of the second outer wall structure 212 matches the radius of the inner wall of the cement mill 1 (see Appendix) Figure 5 At this time, the second outer wall structure 212 is matched and fitted with the inner wall structure of the cement mill 1. The plate body 21 of the liner 2 is made of high-strength wear-resistant material, and the surfaces of the first outer wall structure 211 and the second outer wall structure 212 are both provided with wear-resistant coatings.

[0029] It should be noted that, in this embodiment, the liner 2 is installed on the inner circumferential wall of the cement mill 1, including a plate body 21. The outer wall surface of the plate body 21 near the inner wall of the cement mill 1 is provided with a first outer wall structure 211 and a second outer wall structure 212. The second outer wall structure 212 is symmetrically located on both sides of the first outer wall structure 211. The radius of the first outer wall structure 211 is larger than the radius of the second outer wall structure 212. Both the first outer wall structure 211 and the second outer wall structure 212 are arc-shaped structures, which can match and fit the inner wall of the cement mill 1 cylinder of different diameters.

[0030] The plate 21 is provided with a plurality of mounting holes 22, which are evenly distributed along the length of the plate 21, for fixing the liner 2 to the inner wall of the cement mill 1.

[0031] The plate 21 is made of high-strength wear-resistant material, and the surfaces of the first outer wall structure 211 and the second outer wall structure 212 are both provided with wear-resistant coatings to improve the service life and wear resistance of the liner.

[0032] This application optimizes the design of the liner plate to adapt to cement mill cylinders of different diameters, significantly improving the versatility and wear resistance of the liner plate 2, reducing manufacturing and maintenance costs, while improving grinding efficiency and installation stability. This adaptive cylinder liner plate structure has high application value and promotion prospects, and can effectively solve the limitations of traditional liner plate 2 in use.

[0033] The plate body 21 of the liner is made of high-strength wear-resistant alloy steel, which can withstand high-load impact and wear. The surfaces of the first outer wall structure 211 and the second outer wall structure 212 are coated with tungsten carbide (WC), which has extremely high hardness and wear resistance. The wear-resistant coating can significantly reduce the wear rate of the liner, extend its service life, significantly improve the wear resistance and service life of the liner, and reduce maintenance costs.

[0034] The working process of this utility model:

[0035] When in use, select a suitable outer wall structure (first outer wall structure 211 or second outer wall structure 212) according to the diameter of the cement mill 1 cylinder and fit it against the inner wall of the cylinder. Use the mounting hole 22 to fix the liner 2 on the inner wall of the cement mill 1 to ensure that the liner is tightly fitted to the inner wall of the cylinder. After the material enters the cement mill, the liner 2 protects the mill cylinder from direct impact and wear of the grinding media and materials through its arc structure and wear-resistant coating.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
