Technical Field

[0001] This utility model relates to the field of wear-resistant lining technology, and in particular to a composite inlaid wear-resistant lining. Background Technology

[0002] Wet ball mills are key equipment for further pulverizing materials after they have been crushed. Ball mills are widely used in industries such as cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal ore beneficiation, and glass and ceramics production. Ball mill liners are used to protect the cylinder from direct impact and friction between the grinding media and materials. Different types of liners can also be used to adjust the movement of the grinding media to enhance the pulverizing effect of the grinding media on the materials, thereby improving the grinding efficiency of the mill, increasing output, and reducing metal consumption.

[0003] A search revealed an existing patent (publication number: CN221965526U) that discloses a composite inlaid wear-resistant liner, including a main mechanism, an auxiliary mechanism, and a reinforcing mechanism. When disassembling this composite inlaid wear-resistant liner, brute force is required to pull out the connecting column. This causes the return spring and trapezoidal block to be squeezed and deformed in the mounting hole. At the same time, the return spring and trapezoidal block will squeeze and damage the mounting hole, thus affecting the next installation and reducing the service life of the device.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0022] Please see Figure 1-6 This utility model provides a composite inlaid wear-resistant liner technical solution: including a base 100 and a wear-resistant liner 200. The upper side of the outer wall of the base 100 is symmetrically provided with countersunk holes 110. The interior of the base 100 is provided with a sliding groove 120 communicating with the countersunk holes 110. The lower side of the outer wall of the wear-resistant liner 200 is symmetrically fixedly installed with connecting posts 210. The connecting posts 210 are inserted into the countersunk holes 110. The connecting posts 210 are slidably provided with locking blocks 220 inside the connecting posts 210. The locking blocks 220 are inserted into the sliding groove 120. The wear-resistant liner 200 and the base 100 are fixedly connected by the insertion of the connecting posts 210 into the countersunk holes 110 and the insertion of the locking blocks 220 into the sliding groove 120.

[0023] The connecting column 210 has a sliding groove 221 inside. The snap-fit ​​block 220 is slidably connected to the inner wall of the sliding groove 221. The snap-fit ​​block 220 has an installation groove 230. The sliding groove 120 has an installation groove 240. A spring 250 is fixedly connected between the installation groove 240 and the installation groove 120. The spring 250 can squeeze the snap-fit ​​block 220 to slide into the sliding groove 120.

[0024] The base 100 has symmetrically arranged connecting grooves 400 inside, which communicate with the sliding groove 120. A rotating groove 410 is located in the middle of the base 100. A connecting block 411 is fixedly installed in the middle of the rotating groove 410. A screw 440 is rotatably connected to the connecting block 411. The front end of the outer wall of the screw 440 is rotatably connected to the front end of the inner wall of the rotating groove 410. The threads at the front and rear ends of the side wall of the screw 440 are in opposite directions. Threaded blocks 430 are symmetrically threaded onto the side wall of the screw 440. Each threaded block 430 has a connecting plate 420 fixedly connected to both sides of its outer wall, which is slidably connected to the connecting groove 400. The connecting plate 420 is located away from the screw. A sliding block 300 is fixedly connected to one end of the threaded block 430. A pressing block 310 is fixedly installed at the end of the sliding block 300 near the snap-fit ​​block 220. When the wear-resistant liner 200 needs to be disassembled, the threaded blocks 430 on both sides can be moved away from each other by rotating the screw 440, thereby moving the two pairs of connecting plates 420 away from each other. This, in turn, moves the sliding block 300 and the pressing block 310 closer to the pressing snap-fit ​​block 220, so that the snap-fit ​​block 220 is pressed back into the sliding groove 221. At this time, the snap-fit ​​block 220 is disengaged from the sliding groove 120, and the personnel can then pull the wear-resistant liner 200 to pull the connecting post 210 out of the countersunk hole 110. An internal hex nut 500 is fixedly connected to the rear end of the outer wall of the screw 440. The internal hex nut 500 is used to facilitate the personnel to turn the screw 440 using an external hex wrench.

[0025] like Figure 1 As shown, the wear-resistant liner 200 has protrusion blocks 600 evenly arranged and fixedly connected on the upper side of its outer wall. The protrusion blocks 600 can increase the strength of the wear-resistant liner 200 and improve its service life.

[0026] The working principle of this utility model is as follows: In use, the device achieves a fixed connection between the wear-resistant liner 200 and the base 100 by connecting the connecting column 210 to the countersunk hole 110 and by connecting the snap-fit ​​block 220 to the sliding groove 120. The spring 250 can press the snap-fit ​​block 220 into the sliding groove 120 for sliding insertion. When the wear-resistant liner 200 needs to be disassembled, the screw 440 can be rotated by rotating the internal hex nut 500. By rotating the screw 440, the threaded blocks 430 on the front and rear sides are moved away from each other, thereby driving the two pairs of connecting plates 420 to move away from each other. This, in turn, drives the sliding block 300 and the pressing block 310 to approach and press the snap-fit ​​block 220, so that the snap-fit ​​block 220 is pressed back into the sliding groove 221. At this time, the snap-fit ​​block 220 is disengaged from the sliding groove 120, and the personnel can pull the wear-resistant liner 200 to pull the connecting column 210 out of the countersunk hole 110.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
