Interlocking ceramic patch wear-resistant elbow with tight connection

Abstract

The invention discloses a tightly-connected interlocking ceramic patch wear-resistant elbow, and particularly relates to the technical field of wear-resistant elbows, the wear-resistant elbow comprises a wear-resistant elbow body, the inner wall of the wear-resistant elbow body is in lap joint with the outer surfaces of a plurality of ceramic patches, and the opposite faces of every two corresponding ceramic patches are in lap joint with each other; wherein the inner walls of the eight ceramic patches are fixedly connected with thickening blocks. According to the wear-resistant elbow, the ceramic patches, the wear-resistant elbow, the limiting sliding blocks and the limiting sliding blocks are arranged, so that the wear-resistant elbow can be bonded and fixed through the liquid injection groove after the ceramic patches are placed, and the situation that the mounting efficiency of the ceramic patches is affected due to assembly and bonding of single patches is avoided; and two adjacent ceramic patches can be locked through the mounting concave surfaces and the mounting convex surfaces, so that the ceramic patches in the wear-resistant elbow can be fixed through the positioning rods, the positioning cylinders, the mounting concave surfaces and the mounting convex surfaces, the mounting difficulty of the ceramic patches is reduced, and meanwhile, the stability of the ceramic patches after mounting is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of wear-resistant elbows, and more particularly, to a wear-resistant elbow with interlocking ceramic patches tightly connected. Background technique [0002] The wear of industrial elbows has always been a factor affecting safe and civilized production. With the continuous development of science and technology, materials are also constantly innovating, and materials such as cast stone, cast steel, alloy, and centrifugally cast composite ceramics have appeared one after another. Among them, the pipeline lining alumina ceramics has become one of the most widely used wear-resistant materials due to its high wear resistance, high hardness, good oxidation resistance, good corrosion resistance and high resistance to high and low temperature, occupying the world's special ceramics. About 80% of the market share (wear-resistant materials). [0003] In foreign countries, industrial enterprises generally use ...

Problems solved by technology

[0008] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tightly connected interlocking ceramic patch wear-resistant elbow. The technical problem to be solved by the invention is: the existing wear-resistant elbow is assembled with multiple pieces of patches However, due to the fact that the elbow is in a bent state during actual attachment, some ceramic patches are often difficult to fully adhere to the inside of the elbow, resulting in a gap between the patch and the elbow, which in turn affects the actual shape of the elbow. Installation effect, at the same time, it is too time-consuming to attach a brick by laying bricks. Each piece of ceramic patch needs to be coated with adhesive, which requires a lot of energy from the staff and is not conducive to the assembly of wear-resistant elbows. For the protection of the bending part of the wear-resistant elbow, thickening is often used to increase the wearable thickness of the bending part of the wear-resistant elbow. The erosion of impurities in the liquid will still cause wear on the bending part of the wear-resistant elbow, which not only limits the service life of the pipeline, but also consumes resources and energy of the staff to replace the elbow
