Description

Technical Field

[0001] This utility model belongs to the technical field of ceramic wear-resistant plates, and in particular relates to a ceramic-rubber-steel three-in-one composite liner. Background Technology

[0002] Ceramic composite wear-resistant plates are high-performance wear-resistant materials made by combining high-hardness ceramic materials with a substrate through a special process. Their core advantage lies in combining the high wear resistance of ceramics with the toughness of the matrix, making them widely applicable in heavy-wear environments and significantly extending equipment lifespan. Wear-resistant ceramics, due to their high hardness, have been proven to be among the best wear-resistant materials and are widely used in industries such as mining, cement, power, building materials, and metallurgy. Based on their structure, they can be divided into two categories: integral ceramic wear-resistant plates and composite ceramic wear-resistant plates. Composite types typically use ceramic blocks / sheets embedded or bonded together. There are two main methods for ceramic-metal composite materials: the first method involves first machining round or square holes in a steel plate, then embedding cylindrical or square ceramic blocks into the holes and pouring in adhesive; the second method involves casting ceramic blocks into a metal liner through a casting process, fusing the ceramic blocks and metal liner into a single unit.

[0003] Currently, the first type of ceramic composite wear-resistant plate has the following disadvantages: its ceramic blocks are mostly cylindrical or cubic, usually bonded with polymer adhesives such as rubber, and its metal substrate is often made of ordinary steel plate with poor wear resistance; during long-term use, the adhesive and metal substrate in the gaps between the ceramic blocks are quickly worn away, causing the ceramic blocks to protrude and the bonding surface to decrease, which not only causes the wear-resistant ceramic blocks to fall off, but also increases the risk of brittle fracture.

[0004] In response to the aforementioned problem that the adhesive and metal substrate in the gaps between ceramic blocks are easily worn, causing the wear-resistant ceramic blocks to easily fall off, this utility model designs a ceramic-rubber-steel three-in-one composite liner. Utility Model Content

[0005] The purpose of this utility model is to provide a ceramic-rubber-steel three-in-one composite liner. By designing an interlocking groove structure between the ceramic blocks, the material is not easily washed into the adhesive and metal substrate inside the composite liner during long-term use, thereby ensuring the strong adhesion between the ceramic blocks and the adhesive and solving the problems mentioned above, such as the wear-resistant ceramic blocks falling off and being brittle.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a ceramic-rubber-steel three-in-one composite liner, comprising ceramic blocks and a steel plate structure. The ceramic blocks include ceramic block A and ceramic block B. Adjacent ceramic blocks A and B are provided with interlocking slot structures. The sides of ceramic blocks A and B are respectively provided with convex and concave surfaces, which interlock with each other. A rubber spacer is fixed to the interlocking points in the slot structure using an adhesive. The steel plate structure has uniformly spaced mounting grooves, and a rubber gasket is fixed between the mounting groove and the bottom of the ceramic block using an adhesive. Both the rubber spacer and the rubber gasket are made of highly elastic rubber. From a top-view perspective, the convex and concave surfaces of the slot structure in the ceramic block overlap, allowing material to pass through the composite liner of this utility model... When the plate is being scourted, the material cannot be directly scourted to the deep adhesive and metal substrate inside after being worn down by the scourting. In contrast, with traditional ceramic composite wear-resistant plates, the wear depth increases until it contacts the metal substrate after long-term wear of the adhesive, eventually leading to the detachment of the wear-resistant ceramic block or damage to the ceramic wear-resistant plate, or even wear through it. Because the impact speed and force of the material when impacting the composite liner are relatively large, the impact wear is significant. The groove structure, however, makes it difficult for the material to enter, and the material can only contact the adhesive inside the groove structure and the metal substrate at the bottom after being decelerated by impact on the surface of the composite liner. This greatly avoids internal scour wear. Therefore, it has the advantages of ensuring the strong adhesion between the ceramic block and the adhesive and extending the service life of the product.

[0008] As a preferred embodiment of this utility model, the upper side of the ceramic block A is provided with at least one layer of slot A; after the slot A is provided on the upper side of the ceramic block A, a convex surface is formed on the outer side of the slot A; the upper side of the ceramic block B is provided with at least one layer of slot B, and after the slot B is provided on the upper side of the ceramic block B, a concave surface is formed on the inner side of the slot B; the ceramic blocks A and B are first made into square structures, and their sides are then cut into slot A and slot B by a cutter or cutting tool.

[0009] As a preferred technical solution of this utility model, ceramic block A and ceramic block B are respectively provided with slot A and slot B before high-temperature sintering; ceramic block A and ceramic block B are first made into square structures, and their sides are then processed with slot A and slot B by a cutting tool before sintering; or ceramic block A and ceramic block B with slot A and slot B are made by hot pressing.

[0010] As a preferred technical solution of this utility model, the ceramic block A and the ceramic block B are respectively cut with slot A and slot B after high-temperature sintering; the ceramic block A and the ceramic block B are first made into square structures and then sintered; then their sides are cut off and polished by cutting equipment to obtain slot A and slot B.

[0011] As a preferred technical solution of this utility model, the ceramic block has a square structure; the ceramic block has clearance cuts at its corners; the purpose of the clearance cuts is to cut off the overlapping space between two adjacent ceramic blocks A and between two adjacent ceramic blocks B, so as to avoid the problem of installation failure due to positional conflict during production. The clearance cuts make room for them and ensure smooth production.

[0012] As a preferred technical solution of this utility model, at least one layer of ceramic sheet is fixed to the two adjacent ceramic blocks at the clearance cut by an adhesive; the function of the ceramic sheet is to ensure that the material cannot directly penetrate the deep adhesive and metal substrate when impacted, but is blocked by the ceramic sheet to achieve a protective effect.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model has an interlocking slot structure between the ceramic blocks, which makes it difficult for materials to be washed into the adhesive and metal substrate inside the composite liner during long-term use. This has the advantages of ensuring the strong adhesion between the ceramic blocks and the adhesive, and extending the service life of the product.

[0015] 2. Through the design of the slot structure, this utility model ensures that when materials are flushed, they need to be decelerated by impact on the surface of the composite liner before being bent and then slightly contacting and rubbing the inner adhesive and metal substrate. This degree of wear is far lower than the wear rate of direct flushing. It has the advantages of ensuring the strong adhesion between the ceramic block and the adhesive, and extending the service life of the product.

[0016] 3. This utility model, through the action of ceramic sheets, prevents materials from directly penetrating the deep internal adhesive and metal substrate at the edges and corners during impact, thus providing the advantages of protection and reducing erosion wear.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0037] Example 1

[0038] Please see Figure 1-8As shown, this utility model is a ceramic-rubber-steel three-in-one composite liner, including a ceramic block 1 and a steel plate structure 2; the ceramic block 1 includes ceramic block A101 and ceramic block B102; adjacent ceramic blocks A101 and B102 are provided with interlocking slot structures 3; the sides of ceramic blocks A101 and B102 are respectively provided with convex surfaces 1011 and concave surfaces 1021, which interlock with each other, and the interlocking parts in the slot structure 3 are fixed with rubber partitions 4 by adhesive; the steel plate structure 2 is evenly provided with mounting grooves 201, and rubber gaskets 5 are fixed between the mounting grooves 201 and the bottom of the ceramic block 1 by adhesive; both the rubber partitions 4 and the rubber gaskets 5 are made of high-elasticity rubber; the slot structure 3 in the ceramic block 1, viewed from a top view, has convex surfaces 1011 and concave surfaces 1021 interlocking with each other. The presence of overlapping portions prevents material from being directly washed into the deep adhesive and metal substrate after being worn down by the composite liner of this invention. In contrast, traditional ceramic composite wear-resistant plates experience increasing wear depth after long-term adhesive wear, eventually reaching the metal substrate and leading to the detachment of the wear-resistant ceramic block, damage to the ceramic wear-resistant plate, or even wear through it. Furthermore, the impact speed and force of the material impacting the composite liner result in significant impact wear. The slot structure 3, however, prevents material from easily entering the liner and ensures that the material is decelerated after impacting the surface of the composite liner before contacting the adhesive inside the slot structure 3 and the metal substrate at its bottom. This greatly reduces internal erosion wear. Therefore, it offers advantages such as ensuring a strong bond between the ceramic block and the adhesive, and extending the product's service life.

[0039] Among them, such as Figure 2-4 As shown, the upper side of ceramic block A101 has at least one slot A301; after the slot A301 is formed on the upper side of ceramic block A101, a protruding convex surface 1011 is formed on the outer side of the slot A301; the upper side of ceramic block B102 has at least one slot B302; after the slot B302 is formed on the upper side of ceramic block B102, a concave surface 1021 is formed on the inner side of the slot B302; ceramic blocks A101 and B102 are first made into square structures, and their sides are then cut into slots A301 and B302 by a cutter or cutting tool.

[0040] Among them, such as Figure 2-4 As shown, ceramic blocks A101 and B102 are respectively provided with slots A301 and B302 before high-temperature sintering; ceramic blocks A101 and B102 are first made into square structures, and then slots A301 and B302 are processed on their sides by cutting tools before sintering; or ceramic blocks A101 and B102 with slots A301 and B302 are made by hot pressing.

[0041] Among them, such as Figure 2-4 As shown, ceramic blocks A101 and B102 are cut with slots A301 and B302 respectively after high-temperature sintering. Ceramic blocks A101 and B102 are first made into square structures and then sintered. Their sides are then cut off and polished by cutting equipment to obtain slots A301 and B302.

[0042] Example 2

[0043] A more preferred technical solution based on Embodiment 1 is as follows: Please refer to [link / reference]. Figure 9-12 As shown, ceramic block 1 has a square structure; ceramic block 1 has clearance cuts 103 at its corners; the purpose of clearance cuts 103 is to cut off the overlapping space between two adjacent ceramic blocks A101 and between two adjacent ceramic blocks B102, so as to avoid the problem of position conflict and inability to install during production. Clearance cuts 103 make room for them to ensure smooth production.

[0044] Among them, such as Figure 9 and Figure 12 As shown, at least one layer of ceramic sheet 6 is fixed to the two adjacent ceramic blocks 1 at the clearance cut 103 by an adhesive. The function of the ceramic sheet 6 is to ensure that the material cannot directly penetrate the inner deep adhesive and metal substrate when impacted, but is blocked by the ceramic sheet 6 to achieve a protective effect.

[0045] The outer dimensions of the upper part of ceramic block 1 are all larger than the outer dimensions of the lower part of ceramic block 1, so that the gap between the upper parts of ceramic block 1 is 1mm-10mm and the gap between the lower parts of ceramic block 1 is 5mm-20mm.

[0046] It is worth noting that in the above system embodiments, the various units are divided according to functional logic, but are not limited to the above division, as long as the corresponding functions can be achieved; in addition, the specific names of each functional unit are only for easy differentiation and are not used to limit the protection scope of this utility model.
