Description

Technical Field

[0001] This utility model relates to the technical field of coal mill liner plates, and more specifically, to a composite double-liquid energy-saving liner plate. Background Technology

[0002] Composite dual-liquid energy-saving liners are advanced components specifically designed for internal protection and wear resistance in industrial equipment, widely used in coal mills. The core advantage of this liner lies in its dual-liquid composite material technology. This technology involves mixing two liquid materials with different properties under precisely controlled conditions, followed by curing into a composite material with superior physical and chemical properties. Through this advanced manufacturing process, composite dual-liquid energy-saving liners not only achieve high wear resistance, excellent impact resistance, and superior corrosion resistance, but also effectively reduce energy consumption during equipment operation, significantly extending equipment lifespan, thereby greatly reducing operating costs and maintenance frequency for enterprises.

[0003] However, in practical applications, existing liner systems have some unresolved issues. Traditional liner installation often requires significant time and manpower, and the connection between two liners cannot be completed quickly. This not only affects the assembly speed of the equipment but also limits the flexibility and efficiency of the production line to some extent. Secondly, there is the issue of installation stability: due to the insufficient strength of traditional fixing methods, the installed liners are prone to loosening or even falling off under strong impacts and vibrations. This not only increases the risk of equipment failure but also makes liner replacement and maintenance extremely cumbersome and time-consuming, thus affecting the smoothness and stability of the entire production process.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a composite double-liquid energy-saving liner to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A composite dual-liquid energy-saving liner includes a liner body, which is disposed inside a cylinder. There are multiple liner bodies. A first connecting plate is provided on one side of the liner body, and a second connecting plate is provided on the other side. A fixing mechanism is provided between the first connecting plate and the second connecting plate.

[0008] Furthermore, to ensure the stability of the liner connection, the fixing mechanism includes a groove inside the first connecting plate, a positioning block on one side of the second connecting plate that matches the groove, an installation groove on the first connecting plate and the positioning block, a magnetic buckle inside the installation groove, and through holes on the first and second connecting plates. A first bolt is installed inside the through hole and is threadedly connected to the cylinder.

[0009] Furthermore, to facilitate the disassembly and reuse of the magnetic buckle, the magnetic buckle is provided with a mounting hole, and a second bolt is installed inside the mounting hole.

[0010] Furthermore, in order to improve the overall impact resistance of the liner, the liner body includes a base layer, a buffer layer and a wear-resistant layer, with the buffer layer located outside the base layer and the wear-resistant layer located outside the buffer layer.

[0011] Furthermore, the wear-resistant layer is made of tungsten carbide composite material, and the buffer layer is made of polyurethane material.

[0012] Furthermore, the base layer is made of high-strength alloy steel.

[0013] Furthermore, to enhance the wear resistance of the liner, the outer side of the liner body is corrugated.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) By setting up a fixing mechanism, when the liner needs to be installed, the operator only needs to accurately place the positioning block into the pre-designed groove. With the strong attraction of the magnetic buckle, the liner body can be quickly fixed in the predetermined position. This process not only greatly simplifies the installation steps and saves installation time, but also facilitates the subsequent installation of the first bolt, ensuring the accuracy and convenience of the liner installation. In addition, by setting up the positioning block, we have also effectively increased the connection area between the two liner bodies. This design can not only enhance the contact and interlocking between the two liners, but also significantly improve the firmness and stability of the connection, preventing the liner from loosening or falling off due to vibration or impact during equipment operation.

[0016] (2) By setting a base layer, a buffer layer, and a wear-resistant layer, stress and impact energy can be effectively dispersed, reducing fatigue damage and fracture risk of the liner, thereby extending its service life. At the same time, the multi-layer material structure can also provide better overall stability and rigidity, preventing the liner from deforming or failing during use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] According to an embodiment of the present invention, a composite dual-liquid energy-saving liner is provided.

[0026] Example 1

[0027] like Figures 1-4As shown, the composite dual-liquid energy-saving liner according to an embodiment of the present invention includes a liner body 1, which is disposed inside a cylinder 2. There are multiple liner bodies 1. A first connecting plate 3 is provided on one side of the liner body 1, and a second connecting plate 4 is provided on the other side. A fixing mechanism 5 is provided between the first connecting plate 3 and the second connecting plate 4. The fixing mechanism 5 includes a groove 501 disposed inside the first connecting plate 3. A positioning block 502 is provided on one side of the second connecting plate 4, and the positioning block 502 matches the groove 501. The first connecting plate 3 and the positioning block 502... The upper part is provided with an installation groove 503, and a magnetic buckle 504 is provided inside the installation groove 503. The first connecting plate 3 and the second connecting plate 4 are provided with through holes 505, and a first bolt 506 is provided inside the through holes 505. The first bolt 506 is threadedly connected to the cylinder 2. The magnetic buckle 504 is provided with an installation hole 6, and a second bolt 7 is provided inside the installation hole 6. The magnetic buckle 504 is fixed by the second bolt 7. By providing the second bolt 7, it is easy to disassemble the magnetic buckle 504, so that the magnetic buckle 504 can be reused. The liner body 1 includes a base layer 1. 01. Buffer layer 102 and wear-resistant layer 103. Buffer layer 102 is located outside the base layer 101, and wear-resistant layer 103 is located outside the buffer layer 102. The material of wear-resistant layer 103 is tungsten carbide composite material. Tungsten carbide composite material has extremely high hardness and wear resistance, which can effectively resist particle wear and friction, extend the service life of the liner. In addition, tungsten carbide composite material usually has good high temperature resistance and corrosion resistance, and can maintain stable performance in harsh working environments. The material of buffer layer 102 is polyurethane. Polyurethane has good elasticity and buffering performance, which can effectively absorb impact energy and reduce impact damage to the liner. In addition, polyurethane has good adhesion to ceramic composite material and high-strength alloy steel, which can improve the overall stability and reliability of the liner. The material of base layer 101 is high-strength alloy steel. High-strength alloy steel has excellent strength and toughness, which can provide good support and protection, and prevent the liner from deforming or breaking during use. The outer side of the liner body 1 is provided with corrugations 8. By setting corrugations 8, the wear resistance of the liner body 1 can be effectively enhanced.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In practical applications, when two energy-saving liners need to be installed, the first connecting plate 3 on one side of one liner body 1 is placed above the second connecting plate 4 on the other liner body 1, so that the positioning block 502 is accurately placed into the pre-designed groove 501. With the strong attraction of the magnetic buckle 504, the liner body 1 can be quickly fixed in the predetermined position, and the two liners can be accurately connected. Then, by screwing the first bolt 506 into the cylinder 2, the firmness and stability of the connection between the two liners can be further strengthened, preventing the liners from loosening or falling off due to vibration or impact during equipment operation. When the liner wears down to a certain thickness and the remaining part can no longer play an energy-saving role, it can be recast using 45# steel at the bottom, high-chromium cast iron on the surface, and wear-resistant alloy pillars inlaid in the middle, and cast in two liquids simultaneously to reduce energy consumption.

[0030] In summary, by utilizing the above-mentioned technical solution of this utility model, and by setting the fixing mechanism 5, when the liner needs to be installed, the operator only needs to accurately place the positioning block 502 into the pre-designed groove 501. With the strong attraction of the magnetic buckle 504, the liner body 1 can be quickly fixed in the predetermined position. This process not only greatly simplifies the installation steps and saves installation time, but also facilitates the subsequent installation of the first bolt 506, ensuring the accuracy and convenience of the liner installation. In addition, by setting the positioning block 502, we have also effectively increased the connection area between the two liner bodies 1. This design not only enhances the contact and interlocking between the two liners, but also significantly improves the firmness and stability of the connection, preventing the liner from loosening or falling off due to vibration or impact during equipment operation. Furthermore, by setting the base layer 101, buffer layer 102, and wear-resistant layer 103, stress and impact energy can be effectively dispersed, reducing fatigue damage and fracture risk of the liner, thereby extending its service life. At the same time, the multi-layer material structure can also provide better overall stability and rigidity, preventing the liner from deforming or failing during use.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
