Description

Technical Field

[0001] The invention relates to the technical field of industrial wear-resistant materials, and in particular to a wear-resistant lining plate which is free of welding and easy to disassemble and assemble. Background Art

[0002] In the industrial field, lining plates are an indispensable part of many mechanical equipment. They are mainly used to protect the main structure of the equipment from damage such as wear and corrosion, thereby improving the overall service life and working efficiency of the equipment. Traditional lining plates are usually installed on the equipment by welding or bolting, but these methods have exposed some obvious problems in practical applications.

[0003] The installation of welded linings requires professional welding equipment and operation techniques, which not only increases the installation cost, but also may cause deformation or damage to the lining due to the thermal stress generated during the welding process. In addition, when the welded lining needs to be replaced, the disassembly process is often very complicated, which is not only time-consuming and labor-intensive, but may also cause additional damage to the equipment itself.

[0004] Although bolt-fixed linings are relatively simple to install and remove, the bolted connection parts are prone to loosening, causing the lining to fall off or fail, thus affecting the normal operation of the equipment. At the same time, the bolt-fixing method also requires additional fasteners such as bolts and nuts, which increases material costs and installation complexity.

[0005] Traditional liners, especially single metal liners, have high hardness and strength, but they have limited wear resistance and are easily worn out under the impact and friction of grinding bodies and materials for a long time. Summary of the invention

[0008] Preferably, the top of the fixing column is set as a spherical head, and the outer side of the fixing column is sequentially provided with an arc-shaped protrusion I and an arc-shaped protrusion II below the spherical head, and the mounting holes are snap-fitted with the spherical head, arc-shaped protrusion I and arc-shaped protrusion II to achieve fixation.

[0009] Preferably, the outer dimensions of the spherical head, arc-shaped protrusion I, and arc-shaped protrusion II increase sequentially.

[0010] Preferably, a plurality of S-shaped corrugated grooves are evenly arranged on the top of the alloy layer.

[0011] Preferably, the alloy layer is integrally formed by casting after smelting the chromium-manganese-molybdenum-nickel-silicon alloy.

[0012] Preferably, the rubber layer is integrally formed by injection molding of rubber material.

DETAILED DESCRIPTION

[0018] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, 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.

[0019] A wear-resistant lining plate that is free of welding and easy to disassemble and assemble, as shown in the attached Figure 1-5 As shown, it includes a lining body 1, which includes an alloy layer 2 and a rubber layer 3. Three supporting ribs 4 are arranged at the bottom of the alloy layer 2, and the number of the supporting ribs 4 can be appropriately increased or decreased according to actual conditions. Locking heads 5 are arranged at the bottom of several of the supporting ribs 4, and a plurality of limiting slide grooves 6 matched with the supporting ribs 4 and the locking heads 5 are opened on the top of the rubber layer 3. The supporting ribs 4 and the locking heads 5 are slidably connected with the limiting slide grooves 6, so as to realize a firm connection between the alloy layer 2 and the rubber layer 3. Sawtooth grooves 7 are arranged at both end surfaces of the rubber layer 3, and the serrated grooves 7 are used for realizing the end surface clamping and limiting of two adjacent lining body 1 during installation. Three mounting holes 8 are spaced apart at the bottom of the rubber layer 3. Of course, the number of the mounting holes 8 can also be appropriately increased or decreased according to actual conditions. The three mounting holes 8 are all clamped with fixing columns 9.

[0020] In order to ensure the stability and reliability of the liner body 1 during installation, Figure 4 As shown, the top of the fixing column 9 is set as a spherical head 10, and the outer side of the fixing column 9 is located below the spherical head 10 and is provided with an arc-shaped protrusion Ⅰ11 and an arc-shaped protrusion Ⅱ12 in sequence, and the mounting holes 8 are all engaged with the spherical head 10, the arc-shaped protrusion Ⅰ11, and the arc-shaped protrusion Ⅱ12 to achieve fixation.

[0021] In order to gradually clamp the fixing column 9 in the mounting hole 8 during installation to prevent it from falling off, as shown in the attached Figure 4 As shown, the outer dimensions of the spherical head 10, the arc-shaped protrusion Ⅰ11, and the arc-shaped protrusion Ⅱ12 increase in sequence.

[0022] In order to increase the running height of mineral particles and grinding balls and increase their effective collision probability, Figure 2 As shown, a plurality of S-shaped corrugated grooves 13 are evenly arranged on the top of the alloy layer 2 .

[0023] In order to ensure the strength and good wear resistance of the alloy layer 2, as shown in the following Figure 2 As shown, the alloy layer 2 is integrally formed by smelting and casting the chromium-manganese-molybdenum-nickel-silicon alloy.

[0024] In order to make the rubber layer 3 have good elasticity and wear resistance, be able to buffer and reduce shock, and extend the service life of the lining, as shown in the following Figure 3As shown, the rubber layer 3 is integrally formed and is made of rubber material by injection molding.

[0025] Working principle: As attached Figure 1-6 As shown, first, the mounting hole 8 at the bottom of the rubber layer 3 is clamped with the fixing column 9 fixed on the inner wall of the ball mill, and then the alloy layer 2 is slid to the limited position of the limiting slide groove 6 through the supporting rib 4 and the locking head 5 to realize the rapid installation of the liner body 1. The liner bodies 1 are clamped and fixed by the serrated groove 7 to prevent the liner body 1 from loosening and falling off during operation. At the same time, the installation gap of the liner body 1 is sealed by a sealing strip 14 prepared from the raw material of the rubber layer 3, and the sealing strip 14 is in contact with the end face of the alloy layer 2. The sealing strip 14 can prevent the slurry from penetrating between the liner and the cylinder, and at the same time make the liner structure more compact, thereby increasing the stability of the connection between the liners.

[0026] The present invention is further described below with specific implementation cases: Example 1 The liner, which is assembled from an alloy layer made of Mn 0.7%, Si 0.3%, Ni 0.6%, Mo 0.4%, Cr 3.0%, W 0.1%, C 0.4%, S≤0.02%, P≤0.02% and the rest are Fe, a rubber layer made of natural rubber and an annular magnetic column made of neodymium magnet, is firmly bonded to the cylinder, and no slurry penetrates between the liner and the cylinder. The average power of the ball mill motor in working state is reduced to 1020kW / h, which greatly reduces power consumption and has significant energy-saving effect. The grinding capacity is increased by 20%, the environmental noise is reduced to 72dB, and the service life is extended by 2 months compared with ordinary rubber composite linings, which reduces the replacement frequency, saves time cost and has less wear.

The grinding capacity is increased by 23%, the environmental noise is reduced to 73dB, and the service life is extended by 2.2 months compared with ordinary rubber composite linings, which reduces the replacement frequency, saves time cost and has less wear.
