Description

Technical Field

[0001] The utility model relates to the technical field of lining plates, in particular to a ceramic composite lining plate. Background Art

[0002] After mining and crushing, solid ore usually needs to go through transportation, storage and other links before entering the grinding and beneficiation process. During this process, the ore will cause impact and wear on the conveying chute, ore bin, etc., and due to the large particle size of the ore, it causes great impact. In production practice, lining plates are usually installed on the chute and ore bin walls to protect the equipment from damage.

[0003] Lining materials can generally be divided into the following two categories: metal castings such as ductile iron and high chromium steel; and wear-resistant elastic materials such as rubber and polyurethane. However, under the above working conditions, metal liners are not wear-resistant, and wear-resistant elastic material liners are not impact-resistant, so their service life is very short. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a ceramic composite lining plate.

[0005] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a ceramic composite lining, including a lining body made of wear-resistant elastic material, the top surface of the lining body is a working surface that bears material wear, the bottom surface opposite to the working surface is a mounting surface connected to the machine body, an outer frame is embedded in the working surface, and a plurality of first ceramic blocks are embedded in the outer frame at intervals on the working surface, a buffer layer is provided on the mounting surface, a metal back plate is provided between the buffer layer and the mounting surface of the lining body, the lining body, the first ceramic block, the buffer layer, and the metal back plate are vulcanized into an integrated structure, and a plurality of second ceramic blocks are vulcanized into an integrated structure in the lining body between the metal back plate and the first ceramic block.

[0006] As a preferred technical solution, the lining body is in an arc shape, a cone shape or a flat plate shape.

[0007] As a preferred technical solution, the first ceramic block and the second ceramic block are both cylindrical, hexagonal, cube or cuboid.

[0008] As a preferred technical solution, the wear-resistant elastic material is rubber or polyurethane.

[0009] As a preferred technical solution, the buffer layer is rubber or polyurethane.

[0010] As a preferred technical solution, the thickness of the buffer layer is 5-7 mm.

[0011] As a preferred technical solution, the distance between two adjacent first ceramic blocks is 2-3 mm.

[0012] As a preferred technical solution, the distance between two adjacent second ceramic blocks is 2-3 mm.

[0013] As a preferred technical solution, the liner body is connected to the machine body through locking bolts, the metal back plate is provided with threaded holes for cooperating with the locking bolts, and the buffer layer is provided with installation through holes for the locking bolts to pass through.

[0014] The beneficial effects of the present application are as follows: 1. The present application sets a first ceramic block on the working surface to give full play to the high hardness and high wear resistance of ceramics, making the present application more impact-resistant. The lining body is made of wear-resistant elastic material, and the elasticity of the wear-resistant elastic material forms a buffer, overcoming the disadvantage that ceramics are not impact-resistant. The rigidity of the metal back plate is combined to maintain the shape, size and installation strength of the lining, thereby greatly improving the service life of the lining under high-impact conditions.

[0015] 2. The present application provides a plurality of second ceramic blocks in the lining body between the metal back plate and the first ceramic block, which further improves the strength of the lining and prolongs the service life.

[0016] 3. By setting the outer frame, the first ceramic block at the edge is protected and the service life is extended.

[0017] 4. The present application provides threaded holes on the metal back plate for installation and fixation of the liner. Compared with the existing method of providing installation through holes on the liner, the present application effectively avoids the problem of providing installation through holes on the liner body, which may weaken the overall strength of the liner.
