[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The following is combined with Figure 1-6 To further explain this application,

[0025] The embodiment of the present application discloses a wear-resistant liner for a ball mill that is easy to replace. Figure 1 and Figure 6 A wear-resistant liner for a ball mill that is easy to replace includes a ball mill body 1. Both ends of the ball mill body 1 are provided with flange surfaces 10. The surface of the flange surface 10 is provided with a plurality of flange holes 3. The inner wall of the ball mill body 1 is provided with a liner fixing mechanism 2.

[0026] The liner fixing mechanism 2 includes a support frame 203, the number of which is several. One end of the support frame 203 is slidably connected to the surface of the flange surface 10 and is located on one side of the flange hole 3. The other end of the support frame 203 is provided with a wear-resistant liner body 201. The inner wall of the support frame 203 is threadedly connected to a first screw 202. The first screw 202 is threadedly connected to the inner wall of the wear-resistant liner body 201. The wear-resistant liner body 201 is arranged in an array in the inner cavity of the ball mill body 1. There are several wear lining bodies 201. A dovetail groove 205 is provided on one side of the wear lining body 201. A dovetail block 204 is fixedly installed on the other side of the wear lining body 201. The interior of the dovetail groove 205 is plug-connected with the surface of the dovetail block 204. A connecting groove 206 is provided on the front surface of the wear lining body 201. A connecting block 207 is provided on the rear surface of the wear lining body 201. The interior of the connecting groove 206 is plug-connected with the surface of the connecting block 207.

[0027] Reference Figure 5 The inner cavity of the ball mill body 1 is fixedly connected with a lower lining plate 8, and the inner wall of the lower lining plate 8 is fixedly connected with a shock-proof pad 9. The inner wall of the shock-proof pad 9 is slidably connected with the surface of the wear-resistant lining plate body 201. The shock-proof pad 9 located on the inner wall of the lower lining plate 8 reduces the impact on the ball mill body 1 during operation, thereby increasing the service life of the ball mill;

[0028] Reference Figure 1 The surface of the flange surface 10 is provided with a cover plate 5, and the inner wall of the cover plate 5 is connected to a second screw 4 by a thread. The number of the second screws 4 is several, and the cover plate 5 and the flange surface 10 are threadedly connected through the second screws 4 and the flange hole 3. The second screws 4 make the cover plate 5 and the flange surface 10 fit more closely, and can make the connection between the support frame 203 and the flange surface 10 more stable;

[0029] Reference Figure 2 A support block 6 is fixedly installed on one side of the support frame 203, and the support block 6 is movably connected to one side of the flange surface 10. A sealing ring 7 is fixedly connected to one side of the support block 6 and the support frame 203. The sealing ring 7 is provided to reduce the leakage of dust generated by the material when the ball mill is working, thereby reducing air pollution;

[0030] Reference Figure 3 The inner wall of the dovetail groove 205 is fixedly installed with an anti-collision pad 12, which is made of rubber. When the ball mill is working, the anti-collision pad 12 in the dovetail groove 205 reduces the collision between the wear-resistant liner body 201 and increases the service life of the wear-resistant liner body 201;

[0031] Reference Figure 6A sealing groove 11 is provided on the rear surface of the cover plate 5. The sealing groove 11 is a circular structure. The interior of the sealing groove 11 fits the surface of the sealing ring 7. The setting of the sealing groove 11 further enhances the sealing effect and prevents dust from escaping through the gap between the cover plate 5 and the flange surface 10 when the ball mill body 1 is working.

[0032] Reference Figure 3 and Figure 4 The wear-resistant liner body 201 is shaped like a convex structure, and the material of the wear-resistant liner body 201 is high chromium cast iron. The convex structure of the wear-resistant liner body 201 can effectively prevent the accumulation and jamming of materials inside the ball mill or related equipment. At the same time, the wear-resistant liner is made of high chromium cast iron, which has high wear resistance, toughness and strength, and also has good high temperature resistance and corrosion resistance.

[0033] Working principle: Before use, the staff needs to install the liner fixing mechanism 2 in the ball mill body 1. During installation, first install the shock-absorbing pad 9 on the inner wall of the lower liner 8, then install the lower liner 8 to the inner wall of the ball mill body 1, then drive the wear-resistant liner body 201 to drive the dovetail block 204 to insert into the dovetail groove 205, then insert the connecting block 207 at the front end of the wear-resistant liner body 201 into the connecting groove 206 at the rear end of another wear-resistant liner body 201 to achieve the connection of multiple wear-resistant liner bodies 201, then extend the wear-resistant liner body 201 to the inner wall of the ball mill body 1, and then install the wear-resistant liner on the outermost side. The support frame 203 is installed on the main body 201 by the first screw 202, and one end of the support frame 203 is slid to the surface of the flange surface 10 and located on one side of the flange hole 3, and then the cover plate 5, the support frame 203 and the flange surface 10 are connected by the second screw 4. When removing, unscrew the first screw 202, remove the support frame 203, the support block 6 and the sealing ring 7, and then pull out the dovetail block 204 on the side of the wear-resistant liner body 201 to be removed from the dovetail groove 205, and pull out the connecting block 207 located on the surface of the wear-resistant liner body 201 from the connecting groove 206, so as to achieve the purpose of removing the wear-resistant liner.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
