[0002] Rod mills are widely used in industries such as cement and mining. Composite liners are an important part of rod mills. Due to the impact and grinding of grinding media and materials, the working conditions of composite liners are relatively harsh and they are easily damaged.

[0003] For example, the utility model with the application number 2021211009.6 discloses a bimetal composite liner for a rod mill with a high operating rate. In this bimetal composite liner for a rod mill with a high operating rate, by providing a protective layer on the top of the main board, it can play a protective role for the main board, increase the wear resistance of the main board, make the service life of the main board longer, and at the same time, reduce the probability of damage to the composite liner, avoid the low working efficiency caused by the damage of the composite liner, and make the working efficiency of the rod mill higher.

[0004] Similar to the above application, there are still deficiencies at present:

[0005] After this bimetal composite liner for a rod mill with a high operating rate is installed and fixed on the inner wall of the rod mill, during the high-speed operation of the rod mill, the liner will be separated from the rod mill, and the liner will become loose, etc., resulting in materials flowing out through the gap between the liner and the barrel wall of the rod mill, which requires regular maintenance by staff and is very troublesome to use.

[0006] Therefore, a bimetal composite liner for a rod mill with a high operating rate is designed to optimize the above problems. Content of the Utility Model

[0007] The main purpose of the utility model is to provide a bimetal composite liner for a rod mill with a high operating rate to solve the related technical problems mentioned in the above background technique.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0009] A bimetallic composite lining plate for a high - operating - rate rod mill, comprising a wear - resistant plate. Strip - shaped grooves are symmetrically formed at the top of the wear - resistant plate. Mounting openings are symmetrically formed at the inner bottom walls of the strip - shaped grooves. Limiting plates are movably installed inside the strip - shaped grooves.

Fixed plates are symmetrically installed at the bottom of the rod - mill barrel. An adjusting rod is rotatably installed between the fixed plates. Movable plates are symmetrically threadedly connected to the outer side of the adjusting rod. Rack teeth are evenly arranged on the sides of the movable plates away from each other.

[0010] Preferably: A first heat - conducting plate is fixed to the bottom of the wear - resistant plate. Evacuation holes are evenly formed at the top of the first heat - conducting plate. Heat - conducting tubes corresponding to the evacuation holes are evenly arranged at the bottom of the first heat - conducting plate. An isolation plate is fixed to the bottom of the first heat - conducting plate. Limiting holes corresponding to the heat - conducting tubes are evenly formed at the top of the isolation plate.

[0017] Through the combined use of the first heat conduction plate, evacuation holes, heat conduction tubes, isolation plates, limit holes and the second heat conduction plate, the friction between the rod-shaped medium, the material and the wear-resistant plate inside the rod mill barrel will generate heat. The heat is transferred to the first heat conduction plate through the wear-resistant plate, transferred into the heat conduction tube through the evacuation holes and then transferred to the second heat conduction plate through the heat conduction tube. Then, it is transferred from the second heat conduction plate to the outside of the rod mill barrel, which can quickly evacuate the heat inside the rod mill barrel and improve the protection effect of the bimetal composite lining plate of the high-operation-rate rod mill.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To make the technical solutions of the present invention clearer and more definite for those skilled in the art, the present invention will be further described in detail below in conjunction with the embodiments and the drawings, but the embodiments of the present invention are not limited thereto.

[0023] Embodiment 1

[0024] As Figures 1 - 3As shown in the figure, this embodiment provides a bimetallic composite lining for a high-operating-rate rod mill, which includes a wear-resistant plate 1. Strip-shaped grooves 2 are symmetrically opened at the top of the wear-resistant plate 1. Mounting openings 3 are symmetrically opened at the inner bottom walls of the strip-shaped grooves 2. Limiting plates 4 are movably installed inside the strip-shaped grooves 2. Mounting rods 5 are symmetrically fixed to the bottoms of the limiting plates 4, and the bottom ends of the mounting rods 5 all penetrate through the mounting openings 3 and extend to the bottom of the wear-resistant plate 1. External tooth rings 6 are threadedly installed on the outer sides of the mounting rods 5. A rod mill barrel 7 is arranged at the bottom of the wear-resistant plate 1. Fixed plates 8 are symmetrically installed at the bottom of the rod mill barrel 7. An adjusting rod 9 is rotatably installed between the fixed plates 8. Movable plates 10 are symmetrically threadedly connected to the outer side of the adjusting rod 9. Rack teeth 11 are evenly arranged on the sides of the movable plates 10 away from each other. A first heat-conducting plate 12 is fixed to the bottom of the wear-resistant plate 1. Evacuation holes 13 are evenly opened at the top of the first heat-conducting plate 12. Heat-conducting tubes 14 corresponding to the evacuation holes 13 are evenly arranged at the bottom of the first heat-conducting plate 12. An isolation plate 15 is fixed to the bottom of the first heat-conducting plate 12. Limiting holes 16 corresponding to the heat-conducting tubes 14 are evenly opened at the top of the isolation plate 15. A second heat-conducting plate 17 is fixed to the bottom of the isolation plate 15.

[0025] After the wear-resistant plate 1 is attached to the rod mill barrel 7, the mounting rods 5 are passed through the mounting openings 3 and extend out of the outside of the rod mill barrel 7, and the external tooth rings 6 are tightened upward until the external tooth rings 6 are closely attached to the outside of the rod mill barrel 7. The adjusting rod 9 is rotated so that the two movable plates 10 move towards both ends respectively until the rack teeth 11 on the movable plates 10 mesh with the outer sides of the external tooth rings 6, thereby limiting the external tooth rings 6 and preventing the self-rotation of the external tooth rings 6. At the same time, the limiting plates 4 are limited in the strip-shaped grooves 2 to prevent the self-rotation of the mounting rods 5 and prevent the loosening of the wear-resistant plate 1. The friction between the rod-shaped media, materials and the wear-resistant plate 1 inside the rod mill barrel 7 will generate heat. The heat is transferred to the first heat-conducting plate 12 through the wear-resistant plate 1, transferred into the heat-conducting tubes 14 through the evacuation holes 13 and transferred to the second heat-conducting plate 17 via the heat-conducting tubes 14, and then transferred to the outside of the rod mill barrel 7 by the second heat-conducting plate 17.

[0026] Embodiment 2

[0027] In this embodiment, as Figures 1 - 3 shown, a reinforcing pad is fixed to the bottom of the second heat-conducting plate 17, and cavities are evenly opened inside the protective pad.

[0028] The setting of the reinforcing pad and the cavities increases the protection effect on the second heat-conducting plate 17, improves the shock absorption and protection effect, and reduces the friction and collision noise.

[0029] In this embodiment, the limiting plates 4 are all square plates, and anti-slip layers are fixed to the bottoms of the limiting plates 4.

[0030] The square plates and the anti-slip layers increase the friction between the limiting plates 4 and the strip-shaped grooves 2, and improve the firmness between the limiting plates 4 and the wear-resistant plate 1.

[0031] In this embodiment, handles are fixed at both ends of the adjusting rod 9, and anti-slip patterns are provided on the outer sides of the handles.

[0032] The arrangement of the handles and the anti-slip patterns facilitates the rotation and use of the adjusting rod 9, making the operation more convenient and labor-saving.

[0033] In this embodiment, a reinforcement layer is provided on the top of the wear-resistant plate 1, and the reinforcement layer is an anti-corrosion coating.

[0034] The arrangement of the anti-corrosion coating for reinforcement increases the protection effect on the wear-resistant plate 1 and improves the corrosion resistance.

[0035] As mentioned above, the above are only further embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and concept of the present utility model, makes equivalent substitutions or changes, all belong to the protection scope of the present utility model.
