Description

Technical Field

[0001] The utility model relates to the field of wear-resistant lining plates, in particular to a composite wear-resistant lining plate with anti-sticking material and shedding. Background Art

[0002] Composite wear-resistant linings are widely used in raw material transportation and storage systems in metallurgy, cement, and power systems, such as raw material transportation pipelines, chutes, material storage bins, etc. Through rubber vulcanization, the base steel plate, rubber layer and ceramic block are bonded into a whole to form a composite lining with both impact resistance and wear resistance. The current composite wear-resistant linings have the following problems: First, the gap between the wear-resistant ceramic blocks is too large, which easily makes the wear-resistant ceramic blocks and the filling rubber uneven, causing the material to easily adhere to the ceramic blocks, affecting the use. In addition, the larger gap is filled with vulcanized rubber, which also reduces the overall life of the composite wear-resistant lining; second, the adhesion between the rubber and the ceramic in the composite wear-resistant lining is not strong, which easily causes the ceramic blocks to fall off due to impact, reducing the service life and affecting the use effect. Utility Model Content

[0003] Based on this, it is necessary to provide an anti-sticking material and a composite wear-resistant lining that can be detached to address the above-mentioned technical problems. By improving the structure of the ceramic block, the bonding force between the ceramic block and the rubber can be improved, thereby increasing the impact resistance of the composite wear-resistant lining and avoiding the detachment of the ceramic block.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a composite wear-resistant lining plate with anti-sticking material and shedding, comprising a basic steel plate layer, a rubber layer, and a ceramic layer, the ceramic layer comprising a plurality of ceramic blocks, the ceramic blocks comprising a first body and a second body, two opposite side surfaces of the first body are provided with continuous and uninterrupted first grooves, the first grooves are in the shape of a herringbone fold line, the number of the first grooves is multiple, the total projection length of the first grooves is 30mm-40mm, the width is 2-4mm, the depth is 1.5-3mm, and the two ends of the first grooves are arc-shaped; a second groove is connected between the first body and the second body, the first body and the second body are integrally formed by the second groove, the second groove is an arc-shaped groove that runs through all sides, the width of the second groove is 2-4mm, and the depth is 2-4mm; a third groove is provided on the bottom surface of the second body, the shape of the third groove is a long arc, and the number of the third grooves is multiple.

[0005] Preferably, the upward facing side of the ceramic block is a square with a side length of 30-50 mm.

[0006] Preferably, the thickness of the first body is 15-25 mm, and the thickness of the second body is 4-8 mm.

[0007] Preferably, the ceramic block has four first grooves, two on each of two opposite sides, and the distance between the two first grooves is 5-7 mm.

[0008] Preferably, the number of the third grooves of the ceramic block is 4-8.

[0009] Preferably, the ceramic blocks are evenly and staggeredly arranged on the rubber layer, and the gap between the ceramic blocks is 2-4 mm.

[0010] Preferably, when the ceramic blocks are arranged in an array, the smooth surface of one ceramic block and the surface of an adjacent ceramic block with the first groove are arranged opposite to each other, so that when two adjacent ceramic blocks are combined, at least one of them has a surface with the first groove.

[0011] Preferably, the thickness of the base steel plate layer is 6-8 mm, the side in contact with the rubber layer has a pattern, and the other side is smooth.

[0012] Preferably, four mounting bolts are welded to the smooth surface of the base steel plate layer, and the length of the mounting bolts is 40-60 mm.

[0013] Preferably, the thickness of the rubber layer is 6-12 mm, and through vulcanization, the rubber is filled between adjacent ceramic blocks to connect the base steel plate layer with the ceramic layer.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Continuous and uninterrupted first grooves are arranged on two opposite sides of the first body, and a third groove is arranged on the bottom surface of the second body. By improving the structure of the ceramic block, the bonding force between the ceramic block and the rubber is improved, thereby increasing the impact resistance of the composite wear-resistant lining and preventing the ceramic block from falling off.

[0016] 2. The ceramic blocks are evenly and staggeredly arranged on the rubber layer, and the gap between the ceramic blocks is 2-4mm. The smaller gap makes the wear-resistant ceramic blocks and the filling rubber smoother, which improves the overall life of the composite wear-resistant lining plate and reduces the adhesion of surface materials during use. When the ceramic blocks are arranged in an array, the smooth surface of a ceramic block and the surface of the adjacent ceramic block with the first groove are arranged relative to each other, so that when two adjacent ceramic blocks are combined, at least one of the surfaces has the first groove, which can improve the bonding force between the ceramic block and the rubber.

[0017] 3. The side of the base steel plate layer that contacts the rubber layer has a pattern. This arrangement can improve the bonding strength between the steel plate layer and the rubber, thereby increasing the service life of the composite wear-resistant lining.
