Description

Technical Field

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

[0002] In modern industrial production, silos are important equipment for storing and transporting various materials. During use, their internal linings are subjected to the impact, friction, and corrosion of materials over a long period of time, which can easily lead to wear and damage. This not only reduces the service life of the silo and increases equipment maintenance costs, but may also affect the continuity and stability of production.

[0003] Traditionally, steel is used to line silos.

[0004] However, the aforementioned existing technologies lack sufficient impact resistance, making them prone to cracking and detachment when subjected to large material impacts, thus affecting the use of the silo. Therefore, there is an urgent need for a wear-resistant liner for silos to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a wear-resistant liner for silos, which aims to solve the problem that the existing technology has insufficient impact resistance and is prone to cracking and falling off when subjected to large material impacts, thus affecting the use of the silo.

[0006] To achieve the above objectives, this utility model provides a wear-resistant liner for silos, comprising a base plate and a wear-resistant connecting assembly. The wear-resistant connecting assembly includes a connecting plate, an adhesive layer, multiple corrugated plates, a buffer layer, and a wear-resistant layer. The wear-resistant connecting assembly is disposed above the base plate. The adhesive layer is connected to the base plate and located above it. The connecting plate is fixedly connected to the adhesive layer and located above it. The multiple corrugated plates are respectively fixedly connected to the connecting plate and located on the inner sidewall of the connecting plate. The buffer layer is fixedly connected to the multiple corrugated plates and located above them. The wear-resistant layer is connected to the buffer layer and located above it.

[0007] The wear-resistant connecting component further includes a square frame, which is disposed on the outer wall of the wear-resistant layer.

[0008] The wear-resistant connecting component further includes a corrosion-resistant layer, which is disposed below the substrate.

[0009] The wear-resistant liner for the hopper also includes an installation assembly. The installation assembly is connected to the base plate. The installation assembly includes a connecting lug, a mounting base, and a locking bolt. The connecting lug is fixedly connected to the base plate and located on one side of the base plate. The mounting base is fixedly connected to the connecting lug and located above the connecting lug. The mounting base and the connecting lug each have a round hole, and the round hole is threadedly engaged with the locking bolt.

[0010] The mounting assembly further includes connecting ribs, which are fixedly connected to the base plate and the connecting ear plate, respectively.

[0011] This utility model discloses a wear-resistant liner for a silo. When material impacts the liner, it first contacts the uppermost wear-resistant layer. The wear-resistant layer, with its high hardness, resists friction and impact from the material, reducing surface wear. Next, the impact force is transmitted to the lower buffer layer. The buffer layer absorbs some of the impact energy through its elastic deformation. Simultaneously, multiple corrugated plates further disperse and buffer the impact force, reducing the impact on the underlying structure. The connecting plate then transmits the buffered force to the adhesive layer, which firmly connects the connecting plate to the base plate, ensuring that the force is evenly transmitted to the base plate. The base plate, as the foundation structure, provides stable support for the entire liner. Ultimately, the entire liner effectively resists the impact and wear of the material through the synergistic effect of all layers, ensuring the normal operation of the silo.

Detailed Implementation

[0017] Please see Figures 1 to 3 ,in, Figure 1This is a structural schematic diagram of the wear-resistant liner for a silo according to this utility model. Figure 2 This is a right view of the wear-resistant liner for a silo according to this utility model. Figure 3 This is the utility model Figure 2 A sectional view along line AA.

[0018] This utility model provides a wear-resistant liner for a silo, comprising a base plate 101, a wear-resistant connecting assembly, and an installation assembly. The wear-resistant connecting assembly includes a connecting plate 102, an adhesive layer 103, multiple corrugated plates 104, a buffer layer 105, a wear-resistant layer 107, a square frame 108, and a corrosion-resistant layer 109. The installation assembly includes a connecting lug 110, a mounting base 111, a locking bolt 112, and a connecting rib 113. The mounting base 111 and the connecting lug 110 each have a circular hole 106.

[0019] The wear-resistant connecting assembly is disposed above the substrate 101; the adhesive layer 103 is connected to the substrate 101 and located above the substrate 101; the connecting plate 102 is fixedly connected to the adhesive layer 103 and located above the adhesive layer 103; a plurality of corrugated plates 104 are respectively fixedly connected to the connecting plate 102 and are respectively located on the inner sidewall of the connecting plate 102; the buffer layer 105 is fixedly connected to the plurality of corrugated plates 104 and located above the plurality of corrugated plates 104; and the wear-resistant layer 107 is connected to the buffer layer 105 and located above the buffer layer 105.

[0020] In this embodiment, when material impacts the liner, it first contacts the uppermost wear-resistant layer 107. The wear-resistant layer 107, with its high hardness, resists the friction and impact of the material, reducing surface wear. Next, the impact force is transmitted to the lower buffer layer 105. The buffer layer 105 absorbs some of the impact energy through its elastic deformation. Simultaneously, multiple corrugated plates 104 further disperse and buffer the impact force, reducing the impact on the underlying structure. The connecting plate 102 then transmits the buffered force to the adhesive layer 103. The adhesive layer 103 firmly connects the connecting plate 102 to the substrate 101, ensuring that the force is evenly transmitted to the substrate 101. The substrate 101, as the basic structure, provides stable support for the entire liner. Ultimately, the entire liner effectively resists the impact and wear of the material through the synergistic effect of all layers, ensuring the normal operation of the silo.

[0021] The wear-resistant layer 107 is made of tungsten carbide alloy material. Tungsten carbide is a compound composed of tungsten and carbon. It is a black hexagonal crystal with a metallic luster and a hardness similar to diamond. It is a good conductor of electricity and heat and has stable chemical properties. It is insoluble in water, hydrochloric acid, and sulfuric acid, but readily soluble in a mixture of nitric acid and hydrofluoric acid. Pure tungsten carbide is brittle, and adding a small amount of metals such as titanium and cobalt can reduce its brittleness. In this liner, its extremely high hardness effectively resists the erosion and friction of materials, greatly improving the wear life of the liner and enabling it to maintain good wear resistance even under long-term material friction.

[0022] The buffer layer 105 is made of polyurethane elastomer, an important type of polyurethane synthetic material. It is usually made by addition polymerization of oligomeric polyols, small molecule chain extenders, and isocyanates, with the addition of a small amount of additives. It has the advantages of wide hardness range, high strength, and good wear resistance. It combines the extensibility and high wear resistance of traditional rubber with the high hardness, high strength, and lightweight characteristics of plastics. In this liner, its good elasticity and energy absorption characteristics can quickly absorb the impact energy when the material impacts the liner, playing a buffering role and effectively reducing the damage to the wear-resistant layer 107 and the substrate 101, thus improving the impact resistance of the liner. In addition, this material also has the characteristics of oil resistance, oxygen and ozone resistance, excellent vibration absorption performance, and good low-temperature performance.

[0023] The substrate 101 is made of high-strength alloy steel plate, which is smelted by adding appropriate amounts of alloying elements (such as chromium, nickel, molybdenum, manganese, etc.) to ordinary carbon steel. The addition of these alloying elements gives it high strength while maintaining good toughness, providing a stable support structure for the entire liner and ensuring that the liner is not easily deformed during installation and use.

[0024] The adhesive layer 103 uses polyurethane adhesive. Epoxy resin adhesive has excellent bonding strength, good chemical stability, and strong corrosion resistance, which can firmly connect the substrate 101 to the wear-resistant layer 107 above it, and maintain stable bonding performance in various environments. Polyurethane adhesive has good elasticity and flexibility, a wide bonding range, strong adhesion to a variety of materials, and can adapt to certain deformations, reducing peeling caused by uneven interlayer stress when the liner is impacted.

[0025] Furthermore, the square frame 108 is disposed on the outer side wall of the wear-resistant layer 107.

[0026] In this embodiment, the square frame 108 is used to protect the four sides of the wear-resistant layer 107 from gas corrosion and reduce the occurrence of delamination.

[0027] Furthermore, the corrosion-resistant layer 109 is disposed below the substrate 101.

[0028] In this embodiment, the corrosion-resistant layer 109 is made of a mixture of epoxy resin adhesive and nano-level anti-corrosion particles (such as nano zinc oxide and nano titanium dioxide). The epoxy resin adhesive has extremely strong bonding properties, which can tightly connect the substrate 101 to the inner wall of the silo, enhance the stability of the liner installation, and prevent the liner from loosening or shifting during material impact and vibration. The nano-level anti-corrosion particles have excellent anti-corrosion properties and can form a dense protective film on the bottom of the substrate 101, effectively blocking corrosive media (such as moisture, chemicals in dust, etc.) in the silo from contacting the substrate 101, avoiding corrosion of the bottom of the substrate 101, thereby extending the overall service life of the liner.

[0029] Furthermore, the mounting assembly is connected to the base plate 101, the connecting ear plate 110 is fixedly connected to the base plate 101 and located on one side of the base plate 101, the mounting base 111 is fixedly connected to the connecting ear plate 110 and located above the connecting ear plate 110, the mounting base 111 and the connecting ear plate 110 each have a round hole 106, and the round hole 106 is threadedly engaged with the locking bolt 112.

[0030] In this embodiment, the substrate 101 is placed on the inner wall of the hopper, and then the locking bolt 112 is tightened with the reserved hole to fix the connecting ear plate 110, which is convenient for the installer to operate and use.

[0031] Furthermore, the connecting rib 113 is fixedly connected to the base plate 101 and the connecting ear plate 110 respectively.

[0032] In this embodiment, the connecting rib 113 is used to enhance the connection between the connecting lug 110 and the base plate 101, avoid breakage at the connection point, and extend the service life of the connecting lug 110.

[0033] The above-disclosed embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
