Example Embodiment

[0023] The present invention specifically implements the method process of ultrasonic monitoring pipeline conveying paste filling slurry concentration as follows:

[0024] (1) After entering the area where the paste filling slurry pipeline 6 is being transported in the mine, first find a pipeline location that is not blocked by obstacles and is convenient for monitoring and arranges measuring points; It is placed at the corresponding measuring points on both sides of the transportation pipeline 6, and is fastened with bolts 9. Connect the ultrasonic tester 2 and the sonic probe through the sonic test line 3, and connect the digital display 1 and the ultrasonic tester 2 through the sonic data line 10.

[0025] (2) When working, turn on the ultrasonic tester 2 and press the zero-adjustment button to adjust the zero. After the zero-adjustment, set the pipe distance to the outer diameter of the measured pipeline 6, and press the sampling button to collect the paste slurry being tra...

Abstract

The invention relates to an ultrasonic monitoring method for concentration of paste filling slurry conveyed in a pipeline. A system comprises a probe control system, a data transmission system, a data receiving system and a data acquisition system. An acoustic emitter 4 and an acoustic receiver 8 are arranged at two corresponding test points on two sides of a transportation pipeline 6 through retaining rings 5 and screwed and fixed with a bolt 9. Acoustic test data are transmitted to an ultrasonic tester 2 through an acoustic test line 3 and transmitted to a digital display 1 through an acoustic data line 10, and the concentration of the paste filling slurry in the pipeline is displayed on a screen of the digital display 1. The ultrasonic monitoring method has the advantages that a non-destructive testing technology is adopted, the operation is simple, convenient, safe and rapid, the concentration of the paste filling slurry in the pipeline can be monitored in real time, and the defect that the concentration of the paste filling slurry in the pipeline is deduced directly according to slurry preparation concentration while the influence of environment temperature on the concentration of the paste filling slurry in a transportation process in the mine pipeline is neglected in the traditional monitoring method is overcome.

Description

technical field [0001] The invention relates to a method for ultrasonically monitoring the concentration of paste filling material slurry in pipeline transportation. Background technique [0002] Mine paste filling slurry is an artificial composite slurry prepared by water, tailings or gangue matrix and cementitious materials in a certain proportion. It is transported to the mine filling area through pipelines for mine filling. With the improvement of national awareness of environmental protection and the imminent introduction of the "13th Five-Year Plan", green mining of mines has become more and more important, and mine filling is one of the most effective methods to control the surface subsidence in mining areas. How to do a good job of filling is particularly important. As an important part of mine filling, paste filling slurry transportation is very necessary to monitor its concentration during transportation. The traditional method is mainly to infer the slurry concen...
