Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cylindrical mixers, and in particular relates to a high wear-resistant liner device for cylindrical mixers to prevent material adhesion and wear. Background Technology
[0002] A cylindrical mixer is an industrial piece of equipment widely used in metallurgy, chemical industry, building materials and other industries. It is mainly used for mixing, pelletizing, granulating or wetting powdery and granular materials. Current cylindrical mixers primarily rely on the rotation of the drum itself and gravity to mix materials. During the mixing process, lightweight powders are prone to stratification, while viscous materials may clump together, making it difficult to disperse evenly. This results in uneven mixing, making it difficult to achieve the production objective, requiring multiple mixing operations, which is time-consuming, labor-intensive, and inefficient. Utility Model Content
[0003] To address the above problems, this utility model provides a highly wear-resistant liner device for preventing material adhesion and wear in a cylindrical mixer.
[0004] This utility model is implemented as follows: A high-wear-resistant liner device for preventing material adhesion and wear in a cylindrical mixer includes a cylindrical body with an inlet and an outlet at both ends. The cylindrical body is inclined so that the mixed material can move from the higher side to the lower outlet as the cylindrical body rotates. Multiple first liner mechanisms are inclinedly and continuously and uniformly fixedly laid on the inner wall of the cylindrical body near the inlet. The coverage width 'a' of the multiple first liner mechanisms is 1.5–2.5 m, serving as a first mixing zone to disperse and initially mix the material. Multiple second liner mechanisms are horizontally and continuously and uniformly fixedly laid on the inner wall of the cylindrical body on the side of the first liner mechanisms away from the inlet. The coverage width 'b' of the multiple second liner mechanisms is 2.5–3.5 m, serving as a second... In the second mixing zone, the material is further dispersed and mixed. Multiple third liner mechanisms are horizontally and continuously and uniformly fixedly laid on the inner wall of the cylinder on the side opposite to the first liner mechanism. This third mixing zone is mainly used for material mixing. Through the first, second, and third liner mechanisms, wear on the inner wall of the cylinder is prevented, extending the cylinder's service life. The material is also lifted, causing it to fall from a height, thus dispersing it evenly and achieving uniform mixing. Intermediate liner mechanisms are fixedly laid between the first, second, and third liner mechanisms, covering the inner wall of the cylinder to prevent wear and extend its service life.
[0005] A first baffle is fixedly installed at the diagonal of the upper part of the first liner mechanism, a second baffle is fixedly installed at the central axis of the upper part of the second liner mechanism, and a third baffle is fixedly installed at the central axis of the upper part of the third liner mechanism. The material is lifted up, causing it to fall from a height and disperse evenly. As the cylinder rotates, the material is mixed evenly. Slopes are fixedly installed on both sides of the first baffle, the second baffle, and the third baffle to prevent the material from sticking to the right-angle joints on both sides of the first, second, and third baffles, allowing the material lifted by the first, second, and third baffles to slide smoothly down the slopes into the cylinder.
[0006] Preferably, the first liner mechanism, the second liner mechanism, the third liner mechanism and the intermediate liner are symmetrically provided with through holes at their outer edges. A screw is welded to the inner wall of the cylinder. The screw is positioned corresponding to the through hole and passes through the through hole. A nut is fitted on the screw. Tightening the nut ensures a reliable connection between the first liner mechanism, the second liner mechanism, the third liner mechanism, the intermediate liner and the cylinder.
[0007] Preferably, the first liner mechanism, the second liner mechanism, the third liner mechanism and the intermediate liner are provided with grooves at the through hole. The grooves are connected to the through hole, and the nut is set in the groove. This avoids the nut from being worn by the movement of the material and also avoids the nut from obstructing the movement of the material.
[0008] Preferably, the height of the first, second, and third baffles is 100-130mm and the width is 100-130mm, which ensures both the lifting effect on the material and the stable and reliable quality.
[0009] Preferably, the height of the slope is 40-60mm and the width is 40-60mm.
[0010] Preferably, the first liner mechanism, the second liner mechanism, the third liner mechanism and the intermediate liner are made of wear-resistant ceramic, which improves the service life of the first liner mechanism, the second liner mechanism, the third liner mechanism and the intermediate liner.
[0011] Preferably, the first baffles, the second baffles, the second baffles and the third baffles are arranged continuously, which ensures both the lifting effect on the material and the aesthetically pleasing structure.
[0012] The beneficial effects of this utility model are as follows: Through the first liner mechanism, the second liner mechanism, and the third liner mechanism, the wear of the material on the inner wall of the cylinder is prevented, extending the service life of the cylinder. At the same time, the material can be lifted and dropped from a height, thereby dispersing the material evenly and achieving uniform mixing. The inner wall of the cylinder is covered by the intermediate liner, preventing the material from wearing on the inner wall of the cylinder and extending the service life of the cylinder. There is no need for multiple mixing operations, saving time and effort and improving work efficiency. Attached Figure Description

[0020] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.
[0021] like Figure 1-6The diagram illustrates a high-wear-resistant liner device for preventing material adhesion and wear in a cylindrical mixer. It includes a cylindrical body 1 with an inlet 2 and an outlet 3 at both ends. The cylindrical body 1 is inclined, allowing the mixed material to move from the higher side to the lower side of the outlet 3 as the body rotates. Multiple first liner mechanisms 4 are inclined, continuously, and uniformly fixedly laid on the inner wall of the cylindrical body 1 near the inlet 2. The coverage width 'a' of the multiple first liner mechanisms 4 is 2m, forming a first mixing zone for dispersing and preliminary mixing of the material. Multiple second liner mechanisms 5 are horizontally, continuously, and uniformly fixedly laid on the inner wall of the cylindrical body 1 on the side of the first liner mechanisms 4 facing away from the inlet 2. The coverage width 'b' of the multiple second liner mechanisms 5 is 3m, forming a second mixing zone for further dispersing and mixing of the material. Multiple second liner mechanisms 5 are horizontally, continuously, and uniformly laid on the inner wall of the cylindrical body 1 on the side of the second liner mechanisms 5 facing away from the first liner mechanisms 4. Multiple third liner mechanisms 6 are continuously and uniformly fixedly laid as a third mixing zone, mainly used for material mixing. Through the first liner mechanism 4, the second liner mechanism 5, and the third liner mechanism 6, the wear of the material on the inner wall of the cylinder 1 is prevented, extending the service life of the cylinder 1. At the same time, the material is lifted, so that the material falls from a height, thereby dispersing the material evenly and achieving uniform mixing. Intermediate liner mechanisms 7 are fixedly laid between the first liner mechanism 4, the second liner mechanism 5, and the third liner mechanism 6, covering the inner wall of the cylinder 1 to prevent wear of the material on the inner wall of the cylinder 1 and extend the service life of the cylinder 1. The first liner mechanism 4, the second liner mechanism 5, the third liner mechanism 6, and the intermediate liner mechanism 7 are made of wear-resistant ceramic, which improves the service life of the first liner mechanism 4, the second liner mechanism 5, the third liner mechanism 6, and the intermediate liner mechanism 7. A first baffle 8 is fixedly installed at the diagonal of the upper part of the first liner mechanism 4, a second baffle 9 is fixedly installed at the central axis of the upper part of the second liner mechanism 5, and a third baffle 10 is fixedly installed at the central axis of the upper part of the third liner mechanism 6. The material is lifted up, so that the material falls from a height and is evenly dispersed. As the cylinder 1 rotates, the material is evenly mixed. Slopes 11 are fixedly installed on both sides of the first baffle 8, both sides of the second baffle 9, and both sides of the third baffle 10 to prevent the material from sticking to the right-angle joints on both sides of the first baffle 8, the second baffle 9, and the third baffle 10, so that the material lifted by the first baffle 8, the second baffle 9, and the third baffle 10 can smoothly slide down the slopes 11 into the cylinder 1.
[0022] Symmetrical through holes 12 are provided on the outer edges of the first liner mechanism 4, the second liner mechanism 5, the third liner mechanism 6, and the intermediate liner 7. A screw 13 is welded to the inner wall of the cylinder 1. The screw 13 corresponds to the position of the through hole 12 and passes through the through hole 12. A nut 14 is fitted on the screw 13. The nut 14 is tightened and welded to the screw 13 to ensure a reliable connection between the first liner mechanism 4, the second liner mechanism 5, the third liner mechanism 6, the intermediate liner 7, and the cylinder 1. A groove 15 is provided on the first liner mechanism 4, the second liner mechanism 5, the third liner mechanism 6, and the intermediate liner 7 located at the through hole 12. The groove 15 communicates with the through hole 12. The nut 14 is placed in the groove 15, which avoids wear on the nut 14 caused by the movement of materials and also avoids the nut 14 obstructing the movement of materials.
[0023] The first baffle 8, the second baffle 9, and the third baffle 10 are all 120mm high and 120mm wide, ensuring both effective material lifting and stable, reliable quality. The slope 11 is 50mm high and 50mm wide.
[0024] The first baffle 8, the second baffle 9, the second baffle 9 and the third baffle 10 are continuously arranged, which not only ensures the lifting effect of the material, but also makes the structure aesthetically pleasing.
