the utility model provides a ceramic wear-resisting layer's of inside lining ore pulp pipeline, includes the body, and the body both ends are equipped with the flange, be equipped with the polyurethane layer on the inner wall of flange, the inner wall of body is equipped with ceramic wear-resisting layer, and ceramic wear-resisting layer extends to polyurethane layer terminal surface and bonds with it.
Further, the ceramic wear-resistant layer is glued on the inner wall of the pipe body through AB glue.
Further, the polyurethane layer is bonded on the inner wall of the flange in a hot melt mode.
By adopting the technical scheme, compared with the prior art, the utility model has the following beneficial effects.
According to the utility model, a layer of polyurethane is bonded on the flange connection end face through hot melting, so that the sealing connection can be well realized, the situation of ceramic cracking during flange connection is avoided, meanwhile, the polyurethane has high hardness, but has certain elasticity, the sealing connection stability can be ensured, the wear resistance and ageing resistance of the polyurethane are excellent, and the use requirement of an ore pulp pipeline is fully ensured. The ceramic slurry pipeline has the advantages of simple structure, ingenious design, full advantages of wear resistance, long service life and durability of polyurethane seal, optimizes and improves the existing ceramic slurry pipeline, and is more beneficial to production and use.
