Paste filling material conveying state online monitoring system

Abstract

The invention relates to a pasty fluid filling material conveying state on-line monitoring system which is characterized in that the pasty fluid filling material conveying state on-line monitoring system comprises a batching bin, a main conveying pipeline and an on-line monitoring device, pasty fluid filling materials which are stirred evenly are stored in the batching bin, and a bypass of the on-line monitoring device is arranged on the main conveying pipeline. The main conveying pipeline and the on-line monitoring device are used for guiding the pasty fluid filler from the batching bin respectively, and the on-line monitoring device is used for collecting conveying parameters of the guided pasty fluid filler and then guiding the pasty fluid filler to the main conveying pipeline. The device can monitor the conveying resistance loss, the viscosity and the flow state of the paste filler on line, is connected with a main conveying pipeline in parallel, does not affect the operation of a main conveying system, can prevent pipe blockage accidents, is convenient to debug and maintain, and has great value in underground coal filling mining operation.

Description

technical field [0001] The invention relates to the field of on-line monitoring, in particular to an on-line monitoring system for the conveying state of paste filling materials. Background technique [0002] How to protect the surface environment of coal mining area is a major issue faced by the coal industry. At present, the backfill mining method has been widely used because it can effectively reduce the surface subsidence and deformation and improve the recovery rate. The backfill mining method is a method of feeding backfill material to the goaf as the mining face advances in the mining process to manage ground pressure, control the caving of surrounding rock and surface movement, and fill in the backfill body or the surface. The method of mining under its protection. [0003] Among them, the paste filling method is a method of transporting a good proportion of high-concentration paste-like filling materials to the mining face through pipelines for filling and mining....

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an online monitoring system for the conveying state of paste filling materials, which can monitor the conveying parameters such as the conveying resistance loss, viscosity and fluid state of the paste filling on the premise of not affecting the operation progress of the main conveying pipeline , through the observation of conveying resistance loss, viscosity and fluid state, predict whether the paste filler in the conveying pipeline may be blocked, so as to solve the problem that the paste filler is conveyed in a closed pipeline. If there is a problem in the link, it will lead to the deterioration of the conveying performance. If it cannot be found in time, the problem of pipe blockage will easily occur.
