Abstract

The invention discloses a mine mortar conveying pipeline, which comprises a conveying pipeline. The inner wall of the conveying pipeline is provided with a scour-resistant layer. The conveying pipeline is provided with a floating pressure dividing device with a hollow structure, and the floating pressure dividing device is fixedly and sealingly connected with the conveying pipeline. , and communicate with each other. The end of the floating pressure divider away from the delivery pipeline is a closed end. Inside the floating pressure divider, along the radial direction of the delivery pipeline, there are blocking parts, floating sealing parts and hydraulic oil in sequence from near to far. There is a leaking part under the floating sealing part. The problem of blockage and explosion of the conveying pipeline can be effectively solved by setting a floating partial pressure device. At the same time, the mining mortar conveying pipeline of the present invention has strong adaptability, and only needs to refit the existing conveying pipeline. The coated erosion-resistant layer can The wear resistance of the transportation pipeline is greatly improved, and the service life of the transportation pipeline is greatly extended, which saves the material cost and maintenance cost for the enterprise, and is worthy of large-scale promotion and application.

Description

technical field [0001] The invention relates to the field of mining mortar transportation equipment, in particular to a mining mortar transportation pipeline. Background technique [0002] In the existing mining mortar pipelines, the pipelines often fail prematurely due to wear and tear. Through the analysis of the causes of the wear of the pipelines, it is concluded that the metal pipelines fail mainly due to the erosion and wear of the mortar. If wear-resistant metals are used for As a transmission pipeline, obviously the cost will increase significantly, which will not be conducive to the income generation of the enterprise. At the same time, since the mortar is a semi-fluid with a certain amount of water, it will accumulate and deposit during transportation. If it is not treated in time, it will block the transportation pipeline, cause the transportation operation to stop, and sometimes a pipe burst accident will occur. In order to ensure the stable transportation of th...
