Problems solved by technology

[0002] For a long time, the corner elbows of coal-fired thermal power plants in the electric power industry and related industrial and mining material transportation pipelines are hot-bent cast pipes or low-carbon steel pipes. Due to the rapid erosion and wear of materials, they fail in a short period of time, resulting in frequent replacement of elbows and shutdowns. Welding repairs, a lot of waste of manpower, material resources and funds, increase the number of shutdowns

Abstract

The invention discloses a material conveying pipeline.The material conveying pipeline comprises a steel pipe.A rubber pipe body is attached to the inner wall of the steel pipe.Multiple ceramic chips are embedded to the inner surface of the rubber pipe body and evenly arranged on the inner surface of the pipe body.The ceramic chips are cylinders, the diameter of the ceramic chips is 3 mm, the height of the ceramic chips is 3 mm, and the ceramic chips are zirconia ceramics. The material conveying pipeline has the advantages of a ceramic lining pipe and a rubber lining pipe, and the problems that the rubber lining pipe is not resistant to abrasion and the ceramic lining pipe is disengaged are solved at the same time; the service life of the material conveying pipeline is 8-10 times that of a common rubber pipe and 5-8 times that of steel lining ceramics or steel lining polytetrafluoroethylene.The rubber pipe body and the ceramic blocks are treated through a special process, are tightly jointed and are not prone to disengagement, and the material conveying pipeline is suitable for being used as a denitration pipeline.

Description

technical field [0001] The invention relates to an environmental protection equipment of a power plant, in particular to a material conveying pipeline. Background technique [0002] For a long time, the corner elbows of coal-fired thermal power plants in the electric power industry and related industrial and mining material transportation pipelines are hot-bent cast pipes or low-carbon steel pipes. Due to the rapid erosion and wear of materials, they fail in a short period of time, resulting in frequent replacement of elbows and shutdowns. Welding repairs waste a lot of manpower, material resources and funds, increasing the number of shutdowns. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a material conveying pipeline in which rubber and ceramic blocks are closely bonded together. The wearing surface of the wear-resistant ceramic block is called the working surface, and the ceramic block...
