Device for increasing resistance and regulating pressure in filling slurry pipeline transportation

Abstract

The invention relates to a device for increasing the transportation resistance of slurry in a filling pipeline in a small time line high pressure head mine filling system, and discloses a device for increasing the resistance and regulating the pressure in filling slurry pipeline transportation. The problem that the local pressure in filling slurry pipeline transportation is too large is solved in a mode of increasing the resistance loss of the slurry in the pipeline. The input end and the output end of the device for increasing the resistance and regulating the pressure are both connected to the pipeline for transporting the filling slurry, and the horizontal height of the input end of the device for increasing the resistance and regulating the pressure is larger than that of the output end of the device for increasing the resistance and regulating the pressure. The device is simple in technological process and convenient to install, and the flow state of mortar in the pipeline is stable.

Description

technical field [0001] The invention relates to a device for increasing the conveying resistance of slurry in the filling pipeline in a mine filling system with a small double line high pressure head, and solves the problem of excessive local pressure in the pipeline of filling slurry by increasing the resistance loss of the slurry in the pipeline. Big question. Background technique [0002] With the gradual increase in the proportion of deep mining in mine mining, the vertical depth of filling pipelines increases during deep mining, resulting in smaller filling times and excessive pressure in local pipelines, which urgently need to be effectively resolved. The research and application experience of the method of increasing resistance and pressure regulation is insufficient. At present, methods such as decompression pool, variable-diameter pipe transportation, and return pipe transportation are widely used to decompress. However, these methods have complex management, need t...
