Description

Technical Field

[0001] This utility model relates to the field of industrial wear-resistant materials technology, specifically to a wear-resistant liner that is easy to disassemble and install without welding. Background Technology

[0002] In the industrial sector, liners are an indispensable component of many mechanical devices. They are primarily used to protect the main structure of the equipment from wear, corrosion, and other damage, thereby improving the overall service life and operating efficiency of the equipment. Traditionally, liners are installed on equipment by welding or bolting, but these methods have revealed some significant problems in practical applications.

[0003] The installation of welded fixed liners requires specialized welding equipment and techniques, which not only increases installation costs but may also cause deformation or damage to the liners due to thermal stress generated during welding. Furthermore, when welded fixed liners need to be replaced, the disassembly process is often very complex, time-consuming, labor-intensive, and may cause additional damage to the equipment itself.

[0004] While bolted liners are relatively easy to install and remove, the bolted connections are prone to loosening, leading to liner detachment or failure, which in turn affects the normal operation of the equipment. Furthermore, bolted installation requires additional bolts and nuts, increasing material costs and installation complexity.

[0005] Traditional liners, especially single metal liners, while possessing high hardness and strength, have limited wear resistance and are prone to wear under long-term impact and friction from grinding media and materials. Utility Model Content

[0006] This invention provides a wear-resistant liner that is easy to disassemble and install without welding, in order to solve the problems existing in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] A wear-resistant liner that is easy to assemble and disassemble without welding includes a liner body, which comprises an alloy layer and a rubber layer. The bottom of the alloy layer is provided with a plurality of supporting ribs, and each of the supporting ribs is provided with a locking head. The top of the rubber layer is provided with a plurality of limiting grooves adapted to the supporting ribs and locking heads. The supporting ribs and locking heads are slidably connected to the limiting grooves. The two end faces of the rubber layer are provided with serrated grooves. The bottom of the rubber layer is provided with a plurality of mounting holes spaced apart, and each of the mounting holes is engaged with a fixing post.

[0009] Preferably, the top of the fixing post is a spherical head, and an arc-shaped protrusion I and an arc-shaped protrusion II are arranged sequentially below the spherical head on the outside of the fixing post. The mounting holes are all engaged with the spherical head, the arc-shaped protrusion I, and the arc-shaped protrusion II to achieve fixation.

[0010] Preferably, the external dimensions of the spherical head, arc-shaped protrusion I, and arc-shaped protrusion II increase sequentially.

[0011] Preferably, the top of the alloy layer is uniformly provided with several S-shaped corrugated grooves.

[0012] Preferably, the alloy layer is integrally formed and is cast from a chromium-manganese-molybdenum-nickel-silicon alloy after melting.

[0013] Preferably, the rubber layer is integrally molded from rubber material.

[0014] This utility model has the following beneficial effects:

[0015] (1) The liner of this utility model is made by combining an alloy layer and a rubber layer. After the alloy layer and the rubber layer are combined, they are installed by relying on the sawtooth groove. The liner is in close contact as a whole and is finally fixed by a fixing column. It has the characteristics of being weld-free, easy to disassemble and assemble, compact structure, high grinding efficiency, good wear resistance, high safety and long service life.

[0016] (2) The combination of the alloy layer and the rubber layer is stable and reliable, and has good wear resistance and impact resistance.

[0017] (3) The S-shaped corrugated groove increases the running height of mineral particles and grinding balls and increases their effective collision probability. Attached Figure Description

Detailed Implementation

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] A weld-free, easy-to-disassemble wear-resistant liner, as shown in the attached image. Figure 1-5 As shown, the device includes a liner body 1, which comprises an alloy layer 2 and a rubber layer 3. The alloy layer 2 has three supporting ribs 4 at its bottom. The number of supporting ribs 4 can be increased or decreased depending on the actual situation. Each of the three supporting ribs 4 has a locking head 5 at its bottom. The rubber layer 3 has three limiting grooves 6 at its top that are adapted to the supporting ribs 4 and locking heads 5. The supporting ribs 4 and locking heads 5 are slidably connected to the limiting grooves 6, thereby achieving a stable connection between the alloy layer 2 and the rubber layer 3. The rubber layer 3 has serrated grooves 7 on both ends. These serrated grooves 7 are used to lock and limit the end faces of two adjacent liner bodies 1 during installation. The rubber layer 3 has three mounting holes 8 spaced apart at its bottom. The number of mounting holes 8 can also be increased or decreased depending on the actual situation. Each of the three mounting holes 8 is engaged with a fixing post 9.

[0027] To ensure the stability and reliability of the liner body 1 during installation, as shown in the attached... Figure 4 As shown, the top of the fixing post 9 is set as a spherical head 10, and the outer side of the fixing post 9 is provided with arc-shaped protrusions I11 and II12 in sequence below the spherical head 10. The mounting holes 8 are all engaged with the spherical head 10, arc-shaped protrusions I11 and II12 to achieve fixation.

[0028] To ensure that the fixed column 9 can be gradually tightened into the mounting hole 8 during installation and to prevent it from falling off, as shown in the attached... Figure 4 As shown, the external dimensions of the spherical head 10, the arc-shaped protrusion I 11, and the arc-shaped protrusion II 12 increase sequentially.

[0029] To increase the running height of mineral particles and grinding balls and increase their effective collision probability, as shown in the attached... Figure 2 As shown, the top of the alloy layer 2 is uniformly arranged with several S-shaped corrugated grooves 13.

[0030] To ensure the strength and good wear resistance of alloy layer 2, as shown in the attached... Figure 2 As shown, the alloy layer 2 is integrally formed and is cast from a chromium-manganese-molybdenum-nickel-silicon alloy.

[0031] To ensure that rubber layer 3 has good elasticity and wear resistance, can buffer and absorb shock, and extend the service life of the liner, as shown in the attached... Figure 3 As shown, the rubber layer 3 is integrally molded from rubber material.

[0032] Working principle

[0033] As attached Figure 1-6 As shown, firstly, the rubber layer 3 is clamped to the fixing column 9 fixed to the inner wall of the ball mill through the mounting hole 8 at the bottom. Then, the alloy layer 2 is slid to the position limited by the limiting groove 6 through the supporting rib plate 4 and the locking head 5 to achieve the rapid installation of the liner body 1. The liner bodies 1 are locked together by the sawtooth groove 7 to prevent the liner bodies 1 from loosening and falling off during operation. At the same time, the installation gap of the liner body 1 is sealed by the sealing strip 14 made of the rubber layer 3 material. The sealing strip 14 abuts against the end face of the alloy layer 2. The sealing strip 14 not only prevents the slurry from seeping into the gap between the liner and the cylinder, but also makes the liner structure more compact and increases the stability of the connection between the liners.
